+
+				   4/27
+				   ----
+doc/Makefile.in
+	- install {readline,history}.info out of the source directory if

+	- script from the bash distribution to do shared object and library

+				    ---
+shlib/Makefile.in
+	- made the suffix rule that creates xx.so from xx.c write the
+	  compiler output to `a.o', which is then mv'd to xx.so, because

+	  suffixes other than `.o' for `cc -c' (not even `a.out')
+
+				   9/15
+				   ----

+Makefile.in
+	- AR and ARFLAGS are now substituted by configure, used in recipes

+	- remove `*.exe' in clean target for MS-DOS
+
+Makefile.in
+	- make `readline' target depend on ./libreadline.a

+				   4/13
+				   ----
+doc/Makefile.in
+	- add variable, PSDVI, which is the desired resolution of the
+	  generated postscript files.  Set to 300 because I don't have
+	  any 600-dpi printers
+	- set LANGUAGE= before calling makeinfo, so messages are in English
+	- add rluserman.{info,dvi,ps,html} to appropriate variables
+	- add rules to create rluserman.{info,dvi,ps,html}
+	- install and uninstall rluserman.info, but don't update the directory
+	  file in $(infodir) yet
+
+MANIFEST
+	- add doc/rluserman.{texinfo,info,dvi,ps,html}
+
+				   4/30
+				   ----
+configure.in
+	- updated library version to 4.1
+
+				    5/3
+				    ---
+configure.in
+	- SHLIB_MAJOR and SHLIB_MINOR shared library version numbers are
+	  constructed from $LIBRARY_VERSION and substituted into Makefiles
+
+				    5/5
+				    ---
+support/shlib-install
+	- OSF/1 installs shared libraries like Solaris
+
+Makefile.in
+	- broke the header file install and uninstall into two new targets:
+	  install-headers and uninstall-headers
+	- install and uninstall depend on install-headers and uninstall-headers
+	  respectively
+	- changed install-shared and uninstall-shared targets to depend on
+	  install-headers and uninstall-headers, respectively, so users may
+	  choose to install only the shared libraries.  I'm not sure about
+	  the uninstall one yet -- maybe it should check whether or not
+	  the static libraries are installed and not remove the header files
+	  if they are
+
+				    9/3
+				    ---
+configure.in, config.h.in
+	- added test for memmove (for later use)
+	- changed version to 4.1-beta1

+				   9/21
+				   ----

+This document details the changes between this version, readline-6.2,
+and the previous version, readline-6.1.
+
+1.  Changes to Readline
+
+a.  Fixed a bug that caused the unconverted filename to be added to the list of
+    completions when the application specified filename conversion functions.
+
+b.  Fixed a bug that caused the wrong filename to be passed to opendir when the
+    application has specified a filename dequoting function.
+
+c.  Fixed a bug when repeating a character search in vi mode in the case where
+    there was no search to repeat.
+
+d.  When show-all-if-ambiguous is set, the completion routines no longer insert
+    a common match prefix that is shorter than the text being completed.
+
+e.  The full set of vi editing commands may now be used in callback mode.
+
+f.  Fixed a bug that caused readline to not update its idea of the terminal
+    dimensions while running in `no-echo' mode.
+
+h.  Fixed a bug that caused readline to dump core if an application called
+    rl_prep_terminal without setting rl_instream.
+
+i.  Fixed a bug that caused meta-prefixed characters bound to incremental
+    search forward or backward to not be recognized if they were typed
+    subsequently.
+
+j.  The incremental search code treats key sequences that map to the same
+    functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k.  Fixed a bug in menu-complete that caused it to misbehave with large
+    negative argument.
+
+l.  Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+    at the end of the line.
+
+m.  Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+    as if it were a negative argument.
+
+n.  Fixed a bug that caused directory names in words to be completed to not
+    be dequoted correctly.
+
+2.  New Features in Readline
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.1,
+and the previous version, readline-6.0.
+
+1.  Changes to Readline
+
+a.  The SIGWINCH signal handler now avoids calling the redisplay code if
+    one arrives while in the middle of redisplay.
+
+b.  Changes to the timeout code to make sure that timeout values greater
+    than one second are handled better.
+
+c.  Fixed a bug in the redisplay code that was triggered by a prompt
+    containing invisible characters exactly the width of the screen.
+
+d.  Fixed a bug in the redisplay code encountered when running in horizontal
+    scroll mode.
+
+e.  Fixed a bug that prevented menu completion from properly completing
+    filenames.
+
+f.  Fixed a redisplay bug caused by a multibyte character causing a line to
+    wrap.
+
+g.  Fixed a bug that caused key sequences of two characters to not be
+    recognized when a longer sequence identical in the first two characters
+    was bound.
+
+h.  Fixed a bug that caused history expansion to be attempted on $'...'
+    single-quoted strings.
+
+i.  Fixed a bug that caused incorrect redisplay when the prompt contained
+    multibyte characters in an `invisible' sequence bracketed by \[ and
+    \].
+
+j.  Fixed a bug that caused history expansion to short-circuit after
+    encountering a multibyte character.
+
+k.  Fixed a bug that caused applications using the callback interface to not
+    react to SIGINT (or other signals) until another character arrived.
+
+2.  New Features in Readline
+
+a.  New bindable function: menu-complete-backward.
+
+b.  In the vi insertion keymap, C-n is now bound to menu-complete by default,
+    and C-p to menu-complete-backward.
+
+c.  When in vi command mode, repeatedly hitting ESC now does nothing, even
+    when ESC introduces a bound key sequence.  This is closer to how
+    historical vi behaves.
+
+d.  New bindable function: skip-csi-sequence.  Can be used as a default to
+    consume key sequences generated by keys like Home and End without having
+    to bind all keys.
+
+e.  New application-settable function: rl_filename_rewrite_hook.  Can be used
+    to rewite or modify filenames read from the file system before they are
+    compared to the word to be completed.
+
+f.  New bindable variable: skip-completed-text, active when completing in the
+    middle of a word.  If enabled, it means that characters in the completion
+    that match characters in the remainder of the word are "skipped" rather
+    than inserted into the line.
+
+g.  The pre-readline-6.0 version of menu completion is available as
+    "old-menu-complete" for users who do not like the readline-6.0 version.
+
+h.  New bindable variable: echo-control-characters.  If enabled, and the
+    tty ECHOCTL bit is set, controls the echoing of characters corresponding
+    to keyboard-generated signals.
+
+i.  New bindable variable: enable-meta-key.  Controls whether or not readline
+    sends the smm/rmm sequences if the terminal indicates it has a meta key
+    that enables eight-bit characters.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.0,
+and the previous version, readline-5.2.
+
+1.  Changes to Readline
+
+a.  Fixed a number of redisplay errors in environments supporting multibyte 
+    characters.
+
+b.  Fixed bugs in vi command mode that caused motion commands to inappropriately
+    set the mark.
+
+c.  When using the arrow keys in vi insertion mode, readline allows movement
+    beyond the current end of the line (unlike command mode).
+
+d.  Fixed bugs that caused readline to loop when the terminal has been taken
+    away and reads return -1/EIO.
+
+e.  Fixed bugs in redisplay occurring when displaying prompts containing
+    invisible characters.
+
+f.  Fixed a bug that caused the completion append character to not be reset to
+    the default after an application-specified completion function changed it.
+
+g.  Fixed a problem that caused incorrect positioning of the cursor while in
+    emacs editing mode when moving forward at the end of a line while using
+    a locale supporting multibyte characters.
+
+h.  Fixed an off-by-one error that caused readline to drop every 511th
+    character of buffered input.
+
+i.  Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
+
+j.  Fixed redisplay bugs caused by multiline prompts with invisible characters
+    or no characters following the final newline.
+
+k.  Fixed redisplay bug caused by prompts consisting solely of invisible
+    characters.
+
+l.  Fixed a bug in the code that buffers characters received very quickly in
+    succession which caused characters to be dropped.
+
+m.  Fixed a bug that caused readline to reference uninitialized data structures
+    if it received a SIGWINCH before completing initialzation.
+
+n.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+    and therefore unrepeatable.
+
+o.  Fixed a bug that caused readline to disable echoing when it was being used
+    with an output file descriptor that was not a terminal.
+
+p.  Readline now blocks SIGINT while manipulating internal data structures
+    during redisplay.
+
+q.  Fixed a bug in redisplay that caused readline to segfault when pasting a
+    very long line (over 130,000 characters).
+
+r.  Fixed bugs in redisplay when using prompts with no visible printing
+    characters.
+
+s.  Fixed a bug that caused redisplay errors when using prompts with invisible
+    characters and numeric arguments to a command in a multibyte locale.
+
+t.  Fixed a bug that caused redisplay errors when using prompts with invisible
+    characters spanning more than two physical screen lines.
+
+2.  New Features in Readline
+
+a.  A new variable, rl_sort_completion_matches; allows applications to inhibit
+    match list sorting (but beware: some things don't work right if
+    applications do this).
+
+b.  A new variable, rl_completion_invoking_key; allows applications to discover
+    the key that invoked rl_complete or rl_menu_complete.
+
+c.  The functions rl_block_sigint and rl_release_sigint are now public and
+    available to calling applications who want to protect critical sections
+    (like redisplay).
+
+d.  The functions rl_save_state and rl_restore_state are now public and
+    available to calling applications; documented rest of readline's state
+    flag values.
+
+e.  A new user-settable variable, `history-size', allows setting the maximum
+    number of entries in the history list.
+
+f.  There is a new implementation of menu completion, with several improvements
+    over the old; the most notable improvement is a better `completions
+    browsing' mode.
+
+g.  The menu completion code now uses the rl_menu_completion_entry_function
+    variable, allowing applications to provide their own menu completion
+    generators.
+
+h.  There is support for replacing a prefix  of a pathname with a `...' when
+    displaying possible completions.  This is controllable by setting the
+    `completion-prefix-display-length' variable.  Matches with a common prefix
+    longer than this value have the common prefix replaced with `...'.
+
+i.  There is a new `revert-all-at-newline' variable.  If enabled, readline will
+    undo all outstanding changes to all history lines when `accept-line' is
+    executed.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.2,
+and the previous version, readline-5.1.
+
+1.  Changes to Readline
+
+a.  Fixed a problem that caused segmentation faults when using readline in
+    callback mode and typing consecutive DEL characters on an empty line.
+
+b.  Fixed several redisplay problems with multibyte characters, all having to
+    do with the different code paths and variable meanings between single-byte
+    and multibyte character redisplay.
+
+c.  Fixed a problem with key sequence translation when presented with the
+    sequence \M-\C-x.
+
+d.  Fixed a problem that prevented the `a' command in vi mode from being
+    undone and redone properly.
+
+e.  Fixed a problem that prevented empty inserts in vi mode from being undone
+    properly.
+
+f.  Fixed a problem that caused readline to initialize with an incorrect idea
+    of whether or not the terminal can autowrap.
+
+g.  Fixed output of key bindings (like bash `bind -p') to honor the setting of
+    convert-meta and use \e where appropriate.
+
+h.  Changed the default filename completion function to call the filename
+    dequoting function if the directory completion hook isn't set.  This means
+    that any directory completion hooks need to dequote the directory name,
+    since application-specific hooks need to know how the word was quoted,
+    even if no other changes are made.
+
+i.  Fixed a bug with creating the prompt for a non-interactive search string
+    when there are non-printing characters in the primary prompt.
+
+j.  Fixed a bug that caused prompts with invisible characters to be redrawn
+    multiple times in a multibyte locale.
+
+k.  Fixed a bug that could cause the key sequence scanning code to return the
+    wrong function.
+
+l.  Fixed a problem with the callback interface that caused it to fail when
+    using multi-character keyboard macros.
+
+m.  Fixed a bug that could cause a core dump when an edited history entry was
+    re-executed under certain conditions.
+
+n.  Fixed a bug that caused readline to reference freed memory when attmpting
+    to display a portion of the prompt.
+
+o.  Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
+    the prompt and input line multiple times.
+
+p.  Fixed history expansion to not be confused by here-string redirection.
+
+q.  Readline no longer treats read errors by converting them to newlines, as
+    it does with EOF.  This caused partial lines to be returned from readline().
+
+r.  Fixed a redisplay bug that occurred in multibyte-capable locales when the
+    prompt was one character longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Calling applications can now set the keyboard timeout to 0, allowing
+    poll-like behavior.
+
+b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
+    the default last-ditch startup file.
+
+c.  The history file reading functions now allow windows-like \r\n line
+    terminators.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.1,
+and the previous version, readline-5.0.
+
+1.  Changes to Readline
+
+a.  Fixed a bug that caused multiliine prompts to be wrapped and displayed
+    incorrectly.
+
+b.  Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
+    line correctly.
+
+c.  Fixed a problem in computing the number of invisible characters on the first
+    line of a prompt whose length exceeds the screen width.
+
+d.  Fixed vi-mode searching so that failure preserves the current line rather
+    than the last line in the history list.
+
+e.  Fixed the vi-mode `~' command (change-case) to have the correct behavior at
+    end-of-line when manipulating multibyte characters.
+
+f.  Fixed the vi-mode `r' command (change-char) to have the correct behavior at
+    end-of-line when manipulating multibyte characters.
+
+g.  Fixed multiple bugs in the redisplay of multibyte characters:  displaying
+    prompts longer than the screen width containing multibyte characters,
+
+h.  Fix the calculation of the number of physical characters in the prompt
+    string when it contains multibyte characters.
+
+i.  A non-zero value for the `rl_complete_suppress_append' variable now causes
+    no `/' to be appended to a directory name.
+
+j.  Fixed forward-word and backward-word to work when words contained
+    multibyte characters.
+
+k.  Fixed a bug in finding the delimiter of a `?' substring when performing
+    history expansion in a locale that supports multibyte characters.
+
+l.  Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m.  Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+    of the `convert-meta' variable.
+
+n.  Fixed saving and restoring primary prompt when prompting for incremental   
+    and non-incremental searches; search prompts now display multibyte
+    characters correctly.
+
+o.  Fixed a bug that caused keys originally bound to self-insert but shadowed
+    by a multi-character key sequence to not be inserted.
+
+p.  Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+    dereferenced if NULL (matching the documentation).
+
+q.  Extensive changes to readline to add enough state so that commands
+    requiring additional characters (searches, multi-key sequences, numeric
+    arguments, commands requiring an additional specifier character like
+    vi-mode change-char, etc.) work without synchronously waiting for
+    additional input.
+
+r.  Lots of changes so readline builds and runs on MinGW.
+
+s.  Readline no longer tries to modify the terminal settings when running in
+    callback mode.
+
+t.  The Readline display code no longer sets the location of the last invisible
+    character in the prompt if the \[\] sequence is empty.
+
+u.  The `change-case' command now correctly changes the case of multibyte
+    characters.
+
+v.  Changes to the shared library construction scripts to deal with Windows
+    DLL naming conventions for Cygwin.
+
+w.  Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
+    SIGWINCH.
+
+x.  Fixed the non-incremental search code in vi mode to dispose of any current
+    undo list when copying a line from the history into the current editing
+    buffer.
+
+y.  Fixed a bug that caused reversing the incremental search direction to
+    not work correctly.  
+    
+z.  Fixed the vi-mode `U' command to only undo up to the first time insert mode
+    was entered, as Posix specifies.
+
+aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
+    place.
+
+bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
+    with invisible characters in the prompt in a multibyte locale.
+
+cc. Fixed a bug that could cause the terminal special chars to be bound in the
+    wrong keymap in vi mode.
+
+2.  New Features in Readline
+
+a.  The key sequence sent by the keypad `delete' key is now automatically   
+    bound to delete-char.
+
+b.  A negative argument to menu-complete now cycles backward through the
+    completion list.
+
+c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
+    readline will bind the terminal special characters to their readline
+    equivalents when it's called (on by default).
+
+d.  New bindable command: vi-rubout.  Saves deleted text for possible  
+    reinsertion, as with any vi-mode `text modification' command; `X' is bound
+    to this in vi command mode.
+
+e.  If the rl_completion_query_items is set to a value < 0, readline never
+    asks the user whether or not to view the possible completions.
+
+f.  The `C-w' binding in incremental search now understands multibyte
+    characters.
+
+g.  New application-callable auxiliary function, rl_variable_value, returns 
+    a string corresponding to a readline variable's value.
+
+h.  When parsing inputrc files and variable binding commands, the parser
+    strips trailing whitespace from values assigned to boolean variables
+    before checking them.
+
+i.  A new external application-controllable variable that allows the LINES   
+    and COLUMNS environment variables to set the window size regardless of
+    what the kernel returns.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.0,
+and the previous version, readline-4.3.
+
+1.  Changes to Readline
+
+a.  Fixes to avoid core dumps because of null pointer references in the
+    multibyte character code.
+
+b.  Fix to avoid infinite recursion caused by certain key combinations.
+
+c.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
+
+d.  Readline no longer tries to read ahead more than one line of input, even
+    when more is available.
+
+e.  Fixed the code that adjusts the point to not mishandle null wide
+    characters.
+
+f.  Fixed a bug in the history expansion `g' modifier that caused it to skip
+    every other match.
+
+g.  Fixed a bug that caused the prompt to overwrite previous output when the
+    output doesn't contain a newline and the locale supports multibyte
+    characters.  This same change fixes the problem of readline redisplay
+    slowing down dramatically as the line gets longer in multibyte locales.
+
+h.  History traversal with arrow keys in vi insertion mode causes the cursor
+    to be placed at the end of the new line, like in emacs mode.
+
+i.  The locale initialization code does a better job of using the right
+    precedence and defaulting when checking the appropriate environment
+    variables.
+
+j.  Fixed the history word tokenizer to handle <( and >( better when used as
+    part of bash.
+
+k.  The overwrite mode code received several bug fixes to improve undo.
+
+l.  Many speedups to the multibyte character redisplay code.
+
+m.  The callback character reading interface should not hang waiting to read
+    keyboard input.
+
+n.  Fixed a bug with redoing vi-mode `s' command.
+
+o.  The code that initializes the terminal tracks changes made to the terminal
+    special characters with stty(1) (or equivalent), so that these changes
+    are reflected in the readline bindings.  New application-callable function
+    to make it work:  rl_tty_unset_default_bindings().
+
+p.  Fixed a bug that could cause garbage to be inserted in the buffer when
+    changing character case in vi mode when using a multibyte locale.
+
+q.  Fixed a bug in the redisplay code that caused problems on systems
+    supporting multibyte characters when moving between history lines when the
+    new line has more glyphs but fewer bytes.
+
+r.  Undo and redo now work better after exiting vi insertion mode.
+
+s.  Make sure system calls are restarted after a SIGWINCH is received using
+    SA_RESTART.
+
+t.  Improvements to the code that displays possible completions when using
+    multibyte characters.
+
+u.  Fixed a problem when parsing nested if statements in inputrc files.
+
+v.  The completer now takes multibyte characters into account when looking for
+    quoted substrings on which to perform completion.
+
+w.  The history search functions now perform better bounds checking on the
+    history list.
+
+x.  Change to history expansion functions to treat `^' as equivalent to word 
+    one, as the documention states.
+
+y.  Some changes to the display code to improve display and redisplay of
+    multibyte characters.
+
+z.  Changes to speed up the multibyte character redisplay code.
+
+aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
+    last character of a word if invoked while point was on the word's
+    next-to-last character.
+
+bb. Fixed a bug that could cause incorrect filename quoting when
+    case-insensitive completion was enabled and the word being completed
+    contained backslashes quoting word break characters.
+
+cc. Fixed a bug in redisplay triggered when the prompt string contains
+    invisible characters.
+
+dd. Fixed some display (and other) bugs encountered in multibyte locales
+    when a non-ascii character was the last character on a line.
+
+ee. Fixed some display bugs caused by multibyte characters in prompt strings.
+
+ff. Fixed a problem with history expansion caused by non-whitespace characters
+    used as history word delimiters.
+
+gg. Fixed a problem that could cause readline to refer to freed memory when
+    moving between history lines while doing searches.
+
+hh. Improvements to the code that expands and displays prompt strings
+    containing multibyte characters.
+
+ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
+    to the last `c'hange command for later use with `.'.
+
+jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work   
+    incorrectly.
+
+kk. Fixed a problem in vi-mode that caused the last text modification command
+    to not be remembered across different command lines.
+
+ll. Fixed problems with changing characters and changing case at the end of
+    the line.
+
+mm. Fixed a problem with readline saving the contents of the current line
+    before beginning a non-interactive search.
+
+nn. Fixed a problem with EOF detection when using rl_event_hook.
+
+oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+    arguments.
+
+2.  New Features in Readline
+
+a.  History expansion has a new `a' modifier equivalent to the `g' modifier
+    for compatibility with the BSD csh.
+
+b.  History expansion has a new `G' modifier equivalent to the BSD csh `g'
+    modifier, which performs a substitution once per word.
+
+c.  All non-incremental search operations may now undo the operation of
+    replacing the current line with the history line.
+
+d.  The text inserted by an `a' command in vi mode can be reinserted with
+    `.'.
+
+e.  New bindable variable, `show-all-if-unmodified'.  If set, the readline
+    completer will list possible completions immediately if there is more
+    than one completion and partial completion cannot be performed.
+
+f.  There is a new application-callable `free_history_entry()' function.
+
+g.  History list entries now contain timestamp information; the history file
+    functions know how to read and write timestamp information associated
+    with each entry.
+
+h.  Four new key binding functions have been added:
+
+	rl_bind_key_if_unbound()
+	rl_bind_key_if_unbound_in_map()
+	rl_bind_keyseq_if_unbound()
+	rl_bind_keyseq_if_unbound_in_map()
+
+i.  New application variable, rl_completion_quote_character, set to any
+    quote character readline finds before it calls the application completion
+    function.
+
+j.  New application variable, rl_completion_suppress_quote, settable by an   
+    application completion function.  If set to non-zero, readline does not
+    attempt to append a closing quote to a completed word.
+    
+k.  New application variable, rl_completion_found_quote, set to a non-zero
+    value if readline determines that the word to be completed is quoted.
+    Set before readline calls any application completion function.
+
+l.  New function hook, rl_completion_word_break_hook, called when readline
+    needs to break a line into words when completion is attempted.  Allows
+    the word break characters to vary based on position in the line.
+
+m.  New bindable command: unix-filename-rubout.  Does the same thing as
+    unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n.  When listing completions, directories have a `/' appended if the
+    `mark-directories' option has been enabled.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.3,
+and the previous version, readline-4.2a.
+
+1.  Changes to Readline
+
+a.  Fixed output of comment-begin character when listing variable values.
+
+b.  Added some default key bindings for common escape sequences produced by
+    HOME and END keys.
+
+c.  Fixed the mark handling code to be more emacs-compatible.
+
+d.  A bug was fixed in the code that prints possible completions to keep it
+    from printing empty strings in certain circumstances.
+
+e.  Change the key sequence printing code to print ESC as M\- if ESC is a
+    meta-prefix character -- it's easier for users to understand than \e.
+
+f.  Fixed unstifle_history() to return values that match the documentation.
+
+g.  Fixed the event loop (rl_event_hook) to handle the case where the input
+    file descriptor is invalidated.
+
+h.  Fixed the prompt display code to work better when the application has a
+    custom redisplay function.
+
+i.  Changes to make reading and writing the history file a little faster, and
+    to cope with huge history files without calling abort(3) from xmalloc.
+
+j.  The vi-mode `S' and `s' commands are now undone correctly.
+
+k.  Fixed a problem which caused the display to be messed up when the last
+    line of a multi-line prompt (possibly containing invisible characters)
+    was longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Support for key `subsequences':  allows, e.g., ESC and ESC-a to both
+    be bound to readline functions.  Now the arrow keys may be used in vi
+    insert mode.
+
+b.  When listing completions, and the number of lines displayed is more than
+    the screen length, readline uses an internal pager to display the results.
+    This is controlled by the `page-completions' variable (default on).
+
+c.  New code to handle editing and displaying multibyte characters.
+
+d.  The behavior introduced in bash-2.05a of deciding whether or not to
+    append a slash to a completed name that is a symlink to a directory has
+    been made optional, controlled by the `mark-symlinked-directories'
+    variable (default is the 2.05a behavior).
+
+e.  The `insert-comment' command now acts as a toggle if given a numeric
+    argument:  if the first characters on the line don't specify a
+    comment, insert one; if they do, delete the comment text
+
+f.  New application-settable completion variable:
+    rl_completion_mark_symlink_dirs, allows an application's completion
+    function to temporarily override the user's preference for appending
+    slashes to names which are symlinks to directories.
+
+g.  New function available to application completion functions:
+    rl_completion_mode, to tell how the completion function was invoked
+    and decide which argument to supply to rl_complete_internal (to list
+    completions, etc.).
+
+h.  Readline now has an overwrite mode, toggled by the `overwrite-mode'
+    bindable command, which could be bound to `Insert'.
+
+i.  New application-settable completion variable:
+    rl_completion_suppress_append, inhibits appending of
+    rl_completion_append_character to completed words.
+
+j.  New key bindings when reading an incremental search string:  ^W yanks
+    the currently-matched word out of the current line into the search
+    string; ^Y yanks the rest of the current line into the search string,
+    DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2a,
+and the previous version, readline-4.2.
+
+1.  Changes to Readline
+
+a.  More `const' and type casting fixes.
+
+b.  Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+    overflow problems.
+
+c.  The completion code no longer appends a `/' or ` ' to a match when
+    completing a symbolic link that resolves to a directory name, unless
+    the match does not add anything to the word being completed.  This
+    means that a tab will complete the word up to the full name, but not
+    add anything, and a subsequent tab will add a slash.
+
+d.  Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e.  Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f.  Fixed the tty code so that ^V works more than once.
+
+g.  Changed the use of __P((...)) for function prototypes to PARAMS((...))
+    because the use of __P in typedefs conflicted g++ and glibc.
+
+h.  The completion code now attempts to do a better job of preserving the
+    case of the word the user typed if ignoring case in completions.
+
+i.  Readline defaults to not echoing the input and lets the terminal
+    initialization code enable echoing if there is a controlling terminal.
+
+j.  The key binding code now processes only two hex digits after a `\x'
+    escape sequence, and the documentation was changed to note that the
+    octal and hex escape sequences result in an eight-bit value rather
+    than strict ASCII.
+
+k.  Fixed a few places where negative array subscripts could have occurred.
+    
+l.  Fixed the vi-mode code to use a better method to determine the bounds of
+    the array used to hold the marks, and to avoid out-of-bounds references.
+    
+m.  Fixed the defines in chardefs.h to work better when chars are signed.
+    
+n.  Fixed configure.in to use the new names for bash autoconf macros.
+    
+o.  Readline no longer attempts to define its own versions of some ctype
+    macros if they are implemented as functions in libc but not as macros in
+    <ctype.h>.
+
+p.  Fixed a problem where rl_backward could possibly set point to before
+    the beginning of the line.
+
+q.  Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+    include file problems.
+
+2.  New Features in Readline
+
+a.  Added extern declaration for rl_get_termcap to readline.h, making it a
+    public function (it was always there, just not in readline.h).
+
+b.  New #defines in readline.h:  RL_READLINE_VERSION, currently 0x0402,
+    RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c.  New readline variable:  rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d.  New bindable boolean readline variable:  match-hidden-files.  Controls
+    completion of files beginning with a `.' (on Unix).  Enabled by default.
+
+e.  The history expansion code now allows any character to terminate a
+    `:first-' modifier, like csh.
+
+f.  The incremental search code remembers the last search string and uses
+    it if ^R^R is typed without a search string.
+
+h.  New bindable variable `history-preserve-point'.  If set, the history
+    code attempts to place the user at the same location on each history
+    line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.2,
+and the previous version, readline-4.1.
+
+1.  Changes to Readline
+
+a.  When setting the terminal attributes on systems using `struct termio',
+    readline waits for output to drain before changing the attributes.
+
+b.  A fix was made to the history word tokenization code to avoid attempts to
+    dereference a null pointer.
+
+c.  Readline now defaults rl_terminal_name to $TERM if the calling application
+    has left it unset, and tries to initialize with the resultant value.
+
+d.  Instead of calling (*rl_getc_function)() directly to get input in certain
+    places, readline now calls rl_read_key() consistently.
+
+e.  Fixed a bug in the completion code that allowed a backslash to quote a
+    single quote inside a single-quoted string.
+
+f.  rl_prompt is no longer assigned directly from the argument to readline(),
+    but uses memory allocated by readline.  This allows constant strings to
+    be passed to readline without problems arising when the prompt processing
+    code wants to modify the string.
+
+g.  Fixed a bug that caused non-interactive history searches to return the
+    wrong line when performing multiple searches backward for the same string.
+
+h.  Many variables, function arguments, and function return values are now
+    declared `const' where appropriate, to improve behavior when linking with
+    C++ code.
+
+i.  The control character detection code now works better on systems where
+    `char' is unsigned by default.
+
+j.  The vi-mode numeric argument is now capped at 999999, just like emacs mode.
+
+k.  The Function, CPFunction, CPPFunction, and VFunction typedefs have been
+    replaced with a set of specific prototyped typedefs, though they are
+    still in the readline header files for backwards compatibility.
+
+m.  Nearly all of the (undocumented) internal global variables in the library
+    now have an _rl_ prefix -- there were a number that did not, like
+    screenheight, screenwidth, alphabetic, etc.
+
+n.  The ding() convenience function has been renamed to rl_ding(), though the
+    old function is still defined for backwards compatibility.
+
+o.  The completion convenience functions filename_completion_function,
+    username_completion_function, and completion_matches now have an rl_
+    prefix, though the old names are still defined for backwards compatibility.
+
+p.  The functions shared by readline and bash (linkage is satisfied from bash
+    when compiling with bash, and internally otherwise) now have an sh_ prefix.
+
+q.  Changed the shared library creation procedure on Linux and BSD/OS 4.x so
+    that the `soname' contains only the major version number rather than the
+    major and minor numbers.
+
+r.  Fixed a redisplay bug that occurred when the prompt spanned more than one
+    physical line and contained invisible characters.
+
+s.  Added a missing `includedir' variable to the Makefile.
+
+t.  When installing the shared libraries, make sure symbolic links are relative.
+
+u.  Added configure test so that it can set `${MAKE}' appropriately.
+
+v.  Fixed a bug in rl_forward that could cause the point to be set to before
+    the beginning of the line in vi mode.
+
+w.  Fixed a bug in the callback read-char interface to make it work when a
+    readline function pushes some input onto the input stream with
+    rl_execute_next (like the incremental search functions).
+
+x.  Fixed a file descriptor leak in the history file manipulation code that
+    was tripped when attempting to truncate a non-regular file (like
+    /dev/null).
+
+y.  Changes to make all of the exported readline functions declared in
+    readline.h have an rl_ prefix (rltty_set_default_bindings is now
+    rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
+
+z.  The formatted documentation included in the base readline distribution
+    is no longer removed on a `make distclean'.
+
+aa. Some changes were made to avoid gcc warnings with -Wall.
+
+bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
+    `set keymap EMACS' works.
+
+cc. The history file writing and truncation functions now return a useful
+    status on error.
+
+dd. Fixed a bug that could cause applications to dereference a NULL pointer
+    if a NULL second argument was passed to history_expand().
+
+ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
+    value, rl_read_key() now immediately returns '\n' (which is assumed to   
+    be bound to accept-line).
+
+2.  New Features in Readline
+
+a.  The blink timeout for paren matching is now settable by applications,
+    via the rl_set_paren_blink_timeout() function.
+
+b.  _rl_executing_macro has been renamed to rl_executing_macro, which means
+    it's now part of the public interface.
+
+c.  Readline has a new variable, rl_readline_state, which is a bitmap that
+    encapsulates the current state of the library; intended for use by
+    callbacks and hook functions.
+
+d.  rlfe has a new -l option to log input and output (-a appends to logfile),
+    a new -n option to set the readline application name, and -v and -h
+    options for version and help information.
+
+e.  rlfe can now perform filename completion for the inferior process if the
+    OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
+    inferior's current working directory.
+
+f.  A new file, rltypedefs.h, contains the new typedefs for function pointers
+    and is installed by `make install'.
+
+g.  New application-callable function rl_set_prompt(const char *prompt):
+    expands its prompt string argument and sets rl_prompt to the result.
+
+h.  New application-callable function rl_set_screen_size(int rows, int cols):
+    public method for applications to set readline's idea of the screen
+    dimensions.
+
+i.  The history example program (examples/histexamp.c) is now built as one
+    of the examples.
+
+j.  The documentation has been updated to cover nearly all of the public
+    functions and variables declared in readline.h.
+
+k.  New function, rl_get_screen_size (int *rows, int *columns), returns
+    readline's idea of the screen dimensions.
+
+l.  The timeout in rl_gather_tyi (readline keyboard input polling function)
+    is now settable via a function (rl_set_keyboard_input_timeout()).
+
+m.  Renamed the max_input_history variable to history_max_entries; the old
+    variable is maintained for backwards compatibility.
+
+n.  The list of characters that separate words for the history tokenizer is
+    now settable with a variable:  history_word_delimiters.  The default
+    value is as before.
+
+o.  There is a new history.3 manual page documenting the history library.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.1,
+and the previous version, readline-4.0.
+
+1.  Changes to Readline
+
+a.  Changed the HTML documents so that the table-of-contents is no longer
+    a separate file.
+
+b.  Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
+    OSF/1.
+
+c.  The shared library major and minor versions are now constructed
+    automatically by configure and substituted into the makefiles.
+
+d.  It's now possible to install the shared libraries separately from the
+    static libraries.
+
+e.  The history library tries to truncate the history file only if it is a
+    regular file.
+
+f.  A bug that caused _rl_dispatch to address negative array indices on
+    systems with signed chars was fixed.
+
+g.  rl-yank-nth-arg now leaves the history position the same as when it was
+    called.
+
+h.  Changes to the completion code to handle MS-DOS drive-letter:pathname
+    filenames.
+
+i.  Completion is now case-insensitive by default on MS-DOS.
+
+j.  Fixes to the history file manipulation code for MS-DOS.
+
+k.  Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
+
+l.  Some fixes were made to the redisplay code for better operation on MS-DOS.
+
+m.  The quoted-insert code will now insert tty special chars like ^C.
+
+n.  A bug was fixed that caused the display code to reference memory before
+    the start of the prompt string.
+
+o.  More support for __EMX__ (OS/2).
+
+p.  A bug was fixed in readline's signal handling that could cause infinite
+    recursion in signal handlers.
+
+q.  A bug was fixed that caused the point to be less than zero when rl_forward
+    was given a very large numeric argument.
+
+r.  The vi-mode code now gets characters via the application-settable value
+    of rl_getc_function rather than calling rl_getc directly.
+
+s.  The history file code now uses O_BINARY mode when reading and writing
+    the history file on cygwin32.
+
+t.  Fixed a bug in the redisplay code for lines with more than 256 line
+    breaks.
+
+u.  A bug was fixed which caused invisible character markers to not be
+    stripped from the prompt string if the terminal was in no-echo mode.
+    
+v.  Readline no longer tries to get the variables it needs for redisplay 
+    from the termcap entry if the calling application has specified its
+    own redisplay function.  Readline treats the terminal as `dumb' in
+    this case.
+
+w.  Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+    sequences is redrawn correctly.
+
+x.  Changes to the install and install-shared targets so that the libraries
+    and header files are installed separately.
+
+2.  New Features in Readline
+
+a.  A new Readline `user manual' is in doc/rluserman.texinfo.
+
+b.  Parentheses matching is now always compiled into readline, and enabled
+    or disabled when the value of the `blink-matching-paren' variable is
+    changed.
+
+c.  MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+d.  MS-DOS systems now use ~/_history as the default history file.
+
+e.  history-search-{forward,backward} now leave the point at the end of the
+    line when the string to search for is empty, like
+    {reverse,forward}-search-history.
+
+f.  history-search-{forward,backward} now leave the last history line found
+    in the readline buffer if the second or subsequent search fails.
+
+g.  New function for use by applications:  rl_on_new_line_with_prompt, used
+    when an application displays the prompt itself before calling readline().
+
+h.  New variable for use by applications:  rl_already_prompted.  An application
+    that displays the prompt itself before calling readline() must set this to
+    a non-zero value.
+
+i.  A new variable, rl_gnu_readline_p, always 1.  The intent is that an
+    application can verify whether or not it is linked with the `real'
+    readline library or some substitute.
+
+j.  Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
+    is included in the examples subdirectory, though it is not built
+    by default.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-4.0,
+and the previous version, readline-2.2.
+
+1.  Changes to Readline
+
+a.  The version number is now 4.0, to match the major and minor version
+    numbers on the shared readline and history libraries.  Future
+    releases will maintain the identical numbering.
+
+b.  Fixed a typo in the `make install' recipe that copied libreadline.a
+    to libhistory.old right after installing it.
+
+c.  The readline and history info files are now installed out of the source
+    directory if they are not found in the build directory.
+
+d.  The library no longer exports a function named `savestring' -- backwards
+    compatibility be damned.
+
+e.  There is no longer any #ifdef SHELL code in the source files.
+
+f.  Some changes were made to the key binding code to fix memory leaks and
+    better support Win32 systems.
+
+g.  Fixed a silly typo in the paren matching code -- it's microseconds, not
+    milliseconds.
+
+h.  The readline library should be compilable by C++ compilers.
+
+i.  The readline.h public header file now includes function prototypes for
+    all readline functions, and some changes were made to fix errors in the
+    source files uncovered by the use of prototypes.
+
+j.  The maximum numeric argument is now clamped at 1000000.
+
+k.  Fixes to rl_yank_last_arg to make it behave better.
+
+l.  Fixed a bug in the display code that caused core dumps if the prompt
+    string length exceeded 1024 characters.
+
+m.  The menu completion code was fixed to properly insert a single completion
+    if there is only one match.
+
+n.  A bug was fixed that caused the display code to improperly display tabs
+    after newlines.
+
+o.  A fix was made to the completion code in which a typo caused the wrong
+    value to be passed to the function that computed the longest common
+    prefix of the list of matches.
+
+p.  The completion code now checks the value of rl_filename_completion_desired,
+    which is set by application-supplied completion functions to indicate
+    that filename completion is being performed, to decide whether or not to
+    call an application-supplied `ignore completions' function.
+
+q.  Code was added to the history library to catch history substitutions
+    using `&' without a previous history substitution or search having been
+    performed.
+
+
+2.  New Features in Readline
+
+a.  There is a new script, support/shobj-conf, to do system-specific shared
+    object and library configuration.  It generates variables for configure
+    to substitute into makefiles.  The README file provides a detailed
+    explanation of the shared library creation process.
+
+b.  Shared libraries and objects are now built in the `shlib' subdirectory.
+    There is a shlib/Makefile.in to control the build process.  `make shared'
+    from the top-level directory is still the right way to build shared
+    versions of the libraries.
+
+c.  rlconf.h is now installed, so applications can find out which features
+    have been compiled into the installed readline and history libraries.
+
+d.  rlstdc.h is now an installed header file.
+
+e.  Many changes to the signal handling:
+        o Readline now catches SIGQUIT and cleans up the tty before returning;
+        o A new variable, rl_catch_signals, is available to application writers 
+          to indicate to readline whether or not it should install its own
+          signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+          SIGTTIN, and SIGTTOU;
+        o A new variable, rl_catch_sigwinch, is available to application
+          writers to indicate to readline whether or not it should install its
+          own signal handler for SIGWINCH, which will chain to the calling
+          applications's SIGWINCH handler, if one is installed;
+        o There is a new function, rl_free_line_state, for application signal
+          handlers to call to free up the state associated with the current
+          line after receiving a signal;
+        o There is a new function, rl_cleanup_after_signal, to clean up the
+          display and terminal state after receiving a signal;
+        o There is a new function, rl_reset_after_signal, to reinitialize the
+          terminal and display state after an application signal handler
+          returns and readline continues
+
+f.  There is a new function, rl_resize_terminal, to reset readline's idea of
+    the screen size after a SIGWINCH.
+
+g.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
+    previously private functions with a `_' prefix.  These functions are
+    used when an application wants to write a message to the `message area'
+    with rl_message and have the prompt restored correctly when the message
+    is erased.
+
+h.  New function hook: rl_pre_input_hook, called just before readline starts
+    reading input, after initialization.
+
+i.  New function hook: rl_display_matches_hook, called when readline would
+    display the list of completion matches.  The new function
+    rl_display_match_list is what readline uses internally, and is available
+    for use by application functions called via this hook.
+
+j.  New bindable function, delete-char-or-list, like tcsh.
+
+k.  A new variable, rl_erase_empty_line, which, if set by an application using
+    readline, will cause readline to erase, prompt and all, lines on which the
+    only thing typed was a newline.
+
+l.  There is a new script, support/shlib-install, to install and uninstall
+    the shared readline and history libraries.
+
+m.  A new bindable variable, `isearch-terminators', which is a string
+    containing the set of characters that should terminate an incremental
+    search without being executed as a command.
+
+n.  A new bindable function, forward-backward-delete-char.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-2.2,
+and the previous version, readline-2.1.
+
+1.  Changes to Readline
+
+a.  Added a missing `extern' to a declaration in readline.h that kept
+    readline from compiling cleanly on some systems.
+
+b.  The history file is now opened with mode 0600 when it is written for
+    better security.
+
+c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
+    is done better.
+
+d.  ^G now interrupts incremental searches correctly.
+
+e.  A bug that caused a core dump when the set of characters to be quoted
+    when completing words was empty was fixed.
+
+f.  Fixed a problem in the readline test program rltest.c that caused a core
+    dump.
+
+g.  The code that handles parser directives in inputrc files now displays
+    more error messages.
+
+h.  The history expansion code was fixed so that the appearance of the
+    history comment character at the beginning of a word inhibits history
+    expansion for that word and the rest of the input line.
+
+i.  The code that prints completion listings now behaves better if one or
+    more of the filenames contains non-printable characters.
+
+j.  The time delay when showing matching parentheses is now 0.5 seconds.
+
+
+2.  New Features in Readline
+
+a.  There is now an option for `iterative' yank-last-arg handline, so a user
+    can keep entering `M-.', yanking the last argument of successive history
+    lines.
+
+b.  New variable, `print-completions-horizontally', which causes completion
+    matches to be displayed across the screen (like `ls -x') rather than up
+    and down the screen (like `ls').
+
+c.  New variable, `completion-ignore-case', which causes filename completion
+    and matching to be performed case-insensitively.
+
+d.  There is a new bindable command, `magic-space', which causes history
+    expansion to be performed on the current readline buffer and a space to
+    be inserted into the result.
+
+e.  There is a new bindable command, `menu-complete', which enables tcsh-like
+    menu completion (successive executions of menu-complete insert a single
+    completion match, cycling through the list of possible completions).
+
+f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
+    systems, to insert the text from the Win32 clipboard into the editing
+    buffer.
+
+g.  The key sequence translation code now understands printf-style backslash
+    escape sequences, including \NNN octal escapes.  These escape sequences
+    may be used in key sequence definitions or macro values.
+
+h.  An `$include' inputrc file parser directive has been added.

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the

+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+Basic Installation
+==================
+
+These are installation instructions for Readline-6.2.
+
+The simplest way to compile readline is:
+
+  1. `cd' to the directory containing the readline source code and type
+     `./configure' to configure readline for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes some time.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile readline and build the static readline
+     and history libraries.  If supported, the shared readline and history
+     libraries will be built also.  See below for instructions on compiling
+     the other parts of the distribution.  Typing `make everything' will
+     cause the static and shared libraries (if supported) and the example
+     programs to be built.
+
+  3. Type `make install' to install the static readline and history
+     libraries, the readline include files, the documentation, and, if
+     supported, the shared readline and history libraries.
+
+  4. You can remove the created libraries and object files from the
+     build directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile readline for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the readline developers, and should be used with care.
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It
+uses those values to create a `Makefile' in the build directory,
+and Makefiles in the `doc', `shlib', and `examples'
+subdirectories.  It also creates a `config.h' file containing
+system-dependent definitions.  Finally, it creates a shell script
+`config.status' that you can run in the future to recreate the
+current configuration, a file `config.cache' that saves the
+results of its tests to speed up reconfiguring, and a file
+`config.log' containing compiler output (useful mainly for
+debugging `configure'). 
+
+If you need to do unusual things to compile readline, please try
+to figure out how `configure' could check whether to do them, and
+mail diffs or instructions to <bug-readline@gnu.org> so they can
+be considered for the next release.  If at some point
+`config.cache' contains results you don't want to keep, you may
+remove or edit it. 
+
+The file `configure.in' is used to create `configure' by a
+program called `autoconf'.  You only need `configure.in' if you
+want to change it or regenerate `configure' using a newer version
+of `autoconf'.  The readline `configure.in' requires autoconf
+version 2.50 or newer. 
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile readline for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile readline for one architecture at a
+time in the source code directory.  After you have installed
+readline for one architecture, use `make distclean' before
+reconfiguring for another architecture. 
+
+Installation Names
+==================
+
+By default, `make install' will install the readline libraries in
+`/usr/local/lib', the include files in
+`/usr/local/include/readline', the man pages in `/usr/local/man',
+and the info files in `/usr/local/info'.  You can specify an
+installation prefix other than `/usr/local' by giving `configure'
+the option `--prefix=PATH' or by supplying a value for the
+DESTDIR variable when running `make install'. 
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. 
+If you give `configure' the option `--exec-prefix=PATH', the
+readline Makefiles will use PATH as the prefix for installing the
+libraries.  Documentation and other data files will still use the
+regular prefix. 
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' can not figure out
+automatically, but need to determine by the type of host readline
+will run on.  Usually `configure' can figure that out, but if it
+prints a message saying it can not guess the host type, give it
+the `--host=TYPE' option.  TYPE can either be a short name for
+the system type, such as `sun4', or a canonical name with three
+fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2). 
+
+See the file `config.sub' for the possible values of each field.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: the readline `configure' looks for a site script, but not
+all `configure' scripts do.
+
+Operation Controls
+==================
+
+`configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.
+
+Optional Features
+=================
+
+The readline `configure' recognizes a single `--with-PACKAGE' option:
+
+`--with-curses'
+    This tells readline that it can find the termcap library functions
+    (tgetent, et al.) in the curses library, rather than a separate
+    termcap library.  Readline uses the termcap functions, but does not
+    link with the termcap or curses library itself, allowing applications
+    which link with readline the to choose an appropriate library.
+    This option tells readline to link the example programs with the
+    curses library rather than libtermcap.
+
+`configure' also recognizes two `--enable-FEATURE' options:
+
+`--enable-shared'
+    Build the shared libraries by default on supported platforms.  The
+    default is `yes'.
+
+`--enable-static'
+    Build the static libraries by default.  The default is `yes'.
+ 
+Shared Libraries
+================
+
+There is support for building shared versions of the readline and
+history libraries.  The configure script creates a Makefile in
+the `shlib' subdirectory, and typing `make shared' will cause
+shared versions of the readline and history libraries to be built
+on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
+		library.  The default is `lib'; Cygwin uses `cyg'.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_DLLVERSION The version number for shared libraries that determines API
+		compatibility between readline versions and the underlying
+		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
+		can be overridden at configuration time by defining DLLVERSION
+		in the environment.
+
+SHLIB_DOT	The character used to separate the name of the shared library
+		from the suffix and version information.  The default is `.';
+		systems like Cygwin which don't separate version information
+		from the library name should set this to the empty string.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.  If
+		shared libraries are not supported, this will be set to
+		`unsupported'.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared' or `make'.  The shared libraries will be created in the
+shlib subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'.

+This is a terse description of the new features added to readline-6.2 since
+the release of readline-6.1.
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.

+Introduction
+============
+
+This is the Gnu Readline library, version 6.2.
+
+The Readline library provides a set of functions for use by applications
+that allow users to edit command lines as they are typed in.  Both
+Emacs and vi editing modes are available.  The Readline library includes
+additional functions to maintain a list of previously-entered command
+lines, to recall and perhaps reedit those lines, and perform csh-like
+history expansion on previous commands.
+
+The history facilites are also placed into a separate library, the
+History library, as part of the build process.  The History library
+may be used without Readline in applications which desire its
+capabilities.
+
+The Readline library is free software, distributed under the terms of
+the [GNU] General Public License as published by the Free Software
+Foundation, version 3 of the License.  For more information, see the
+file COPYING.
+
+To build the library, try typing `./configure', then `make'.  The
+configuration process is automated, so no further intervention should
+be necessary.  Readline builds with `gcc' by default if it is
+available.  If you want to use `cc' instead, type
+
+        CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+        env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.
+
+The file rlconf.h contains C preprocessor defines that enable and disable
+certain Readline features.
+
+The special make target `everything' will build the static and shared
+libraries (if the target platform supports them) and the examples.
+
+Examples
+========
+
+There are several example programs that use Readline features in the
+examples directory.  The `rl' program is of particular interest.  It
+is a command-line interface to Readline, suitable for use in shell
+scripts in place of `read'.
+
+Shared Libraries
+================
+
+There is skeletal support for building shared versions of the
+Readline and History libraries.  The configure script creates
+a Makefile in the `shlib' subdirectory, and typing `make shared'
+will cause shared versions of the Readline and History libraries
+to be built on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
+		library.  The default is `lib'; Cygwin uses `cyg'.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_DLLVERSION The version number for shared libraries that determines API
+		compatibility between readline versions and the underlying
+		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
+		can be overridden at configuration time by defining DLLVERSION
+		in the environment.
+
+SHLIB_DOT	The character used to separate the name of the shared library
+		from the suffix and version information.  The default is `.';
+		systems like Cygwin which don't separate version information
+		from the library name should set this to the empty string.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared'.  The shared libraries will be created in the shlib
+subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'. 
+
+Documentation
+=============
+
+The documentation for the Readline and History libraries appears in
+the `doc' subdirectory.  There are three texinfo files and a
+Unix-style manual page describing the facilities available in the
+Readline library.  The texinfo files include both user and
+programmer's manuals.  HTML versions of the manuals appear in the
+`doc' subdirectory as well. 
+
+Reporting Bugs
+==============
+
+Bug reports for Readline should be sent to:
+
+        bug-readline@gnu.org
+
+When reporting a bug, please include the following information:
+
+        * the version number and release status of Readline (e.g., 4.2-release)
+        * the machine and OS that it is running on
+        * a list of the compilation flags or the contents of `config.h', if
+          appropriate
+        * a description of the bug
+        * a recipe for recreating the bug reliably
+        * a fix for the bug if you have one!
+
+If you would like to contact the Readline maintainer directly, send mail
+to bash-maintainers@gnu.org.
+
+Since Readline is developed along with bash, the bug-bash@gnu.org mailing
+list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
+Readline bug reports and fixes.

+Subject: Use of Readline
+Reply-to: rms@gnu.org
+
+I think Allbery's suggestion is a good one.  So please add this text
+in a suitable place.  Please don't put it in the GPL itself; that
+should be the same as the GPL everywhere else.  Putting it in the
+README and/or the documentation would be a good idea.
+
+
+======================================================================
+Our position on the use of Readline through a shared-library linking
+mechanism is that there is no legal difference between shared-library
+linking and static linking--either kind of linking combines various
+modules into a single larger work.  The conditions for using Readline
+in a larger work are stated in section 3 of the GNU GPL.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+@c hence no sectioning command or @node.

+Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@enumerate 0
+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+  Copyright (C)  @var{year}  @var{your name}.
+  Permission is granted to copy, distribute and/or modify this document
+  under the terms of the GNU Free Documentation License, Version 1.3
+  or any later version published by the Free Software Foundation;
+  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+  Texts.  A copy of the license is included in the section entitled ``GNU
+  Free Documentation License''.
+@end group

+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:
+
+@smallexample
+@group
+    with the Invariant Sections being @var{list their titles}, with
+    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+    being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+
+CCOOPPYYRRIIGGHHTT
+       The GNU History Library is Copyright (C) 1989-2011 by the Free Software
+       Foundation, Inc.
+
+DDEESSCCRRIIPPTTIIOONN
+       Many programs read input from the user a line at a time.  The GNU  His-
+       tory  library is able to keep track of those lines, associate arbitrary
+       data with each line, and utilize information  from  previous  lines  in
+       composing new ones.
+
+
+HHIISSTTOORRYY EEXXPPAANNSSIIOONN
+       The  history library supports a history expansion feature that is iden-
+       tical to the history expansion in bbaasshh..  This  section  describes  what
+       syntax features are available.
+
+       History expansions introduce words from the history list into the input
+       stream, making it easy to repeat commands, insert the  arguments  to  a
+       previous command into the current input line, or fix errors in previous
+       commands quickly.
+
+       History expansion is usually performed  immediately  after  a  complete
+       line  is read.  It takes place in two parts.  The first is to determine
+       which line from the history list to use during substitution.  The  sec-
+       ond  is  to select portions of that line for inclusion into the current
+       one.  The line selected from the history is the _e_v_e_n_t, and the portions
+       of  that  line  that  are  acted upon are _w_o_r_d_s.  Various _m_o_d_i_f_i_e_r_s are
+       available to manipulate the selected words.  The line  is  broken  into
+       words in the same fashion as bbaasshh does when reading input, so that sev-
+       eral words that would otherwise be separated are  considered  one  word

+       grams.
+
+   IInnttrroodduuccttiioonn ttoo HHiissttoorryy
+       The programmer using the History library has  available  functions  for
+       remembering  lines on a history list, associating arbitrary data with a
+       line, removing lines from the list, searching through the  list  for  a
+       line  containing  an arbitrary text string, and referencing any line in
+       the list directly.  In addition, a history _e_x_p_a_n_s_i_o_n function is avail-
+       able  which  provides  for a consistent user interface across different
+       programs.
+
+       The user using programs written with the History library has the  bene-
+       fit  of  a  consistent user interface with a set of well-known commands
+       for manipulating the text of previous lines and using that text in  new
+       commands.  The basic history manipulation commands are identical to the
+       history substitution provided by bbaasshh.
+
+       If the programmer desires, he  can  use  the  Readline  library,  which
+       includes some history manipulation by default, and has the added advan-
+       tage of command line editing.
+
+       Before declaring any functions  using  any  functionality  the  History
+       library  provides  in  other code, an application writer should include
+       the file  _<_r_e_a_d_l_i_n_e_/_h_i_s_t_o_r_y_._h_>  in  any  file  that  uses  the  History
+       library's  features.   It  supplies  extern declarations for all of the
+       library's public functions and variables, and declares all of the  pub-
+       lic data structures.
+
+
+   HHiissttoorryy SSttoorraaggee
+       The  history  list  is an array of history entries.  A history entry is
+       declared as follows:
+
+       _t_y_p_e_d_e_f _v_o_i_d _* hhiissttddaattaa__tt;;
+
+       typedef struct _hist_entry {
+         char *line;
+         char *timestamp;
+         histdata_t data;
+       } HIST_ENTRY;
+
+       The history list itself might therefore be declared as
+
+       _H_I_S_T___E_N_T_R_Y _*_* tthhee__hhiissttoorryy__lliisstt;;
+
+       The state of the History library is encapsulated into a  single  struc-
+       ture:
+
+       /*
+        * A structure used to pass around the current state of the history.
+        */
+       typedef struct _hist_state {
+         HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+         int offset;           /* The location pointer within this array. */
+         int length;           /* Number of elements within this array. */
+         int size;             /* Number of slots allocated to this array. */
+         int flags;
+       } HISTORY_STATE;
+
+       If  the flags member includes HHSS__SSTTIIFFLLEEDD, the history has been stifled.

+
+       _i_n_t hhiissttoorryy__bbaassee
+       The logical offset of the first entry in the history list.
+
+       _i_n_t hhiissttoorryy__lleennggtthh
+       The number of entries currently stored in the history list.
+
+       _i_n_t hhiissttoorryy__mmaaxx__eennttrriieess
+       The maximum number of history entries.  This must be changed using ssttii--

+
+       _i_n_t hhiissttoorryy__wwiittee__ttiimmeessttaammppss
+       If non-zero, timestamps are written to the history file, so they can be
+       preserved between sessions.  The default value is 0, meaning that time-
+       stamps are not saved.  The current timestamp format uses the  value  of
+       _h_i_s_t_o_r_y___c_o_m_m_e_n_t___c_h_a_r  to delimit timestamp entries in the history file.
+       If that variable does not have a value (the default),  timestamps  will
+       not be written.
+
+       _c_h_a_r hhiissttoorryy__eexxppaannssiioonn__cchhaarr
+       The character that introduces a history event.  The default is !!.  Set-
+       ting this to 0 inhibits history expansion.
+
+       _c_h_a_r hhiissttoorryy__ssuubbsstt__cchhaarr
+       The character that invokes word substitution if found at the start of a
+       line.  The default is ^^.
+
+       _c_h_a_r hhiissttoorryy__ccoommmmeenntt__cchhaarr
+       During  tokenization,  if this character is seen as the first character
+       of a word, then it and all subsequent characters up to  a  newline  are
+       ignored,  suppressing  history expansion for the remainder of the line.
+       This is disabled by default.
+
+       _c_h_a_r _* hhiissttoorryy__wwoorrdd__ddeelliimmiitteerrss
+       The  characters  that  separate  tokens  for  hhiissttoorryy__ttookkeenniizzee(()).   The
+       default value is "" \\tt\\nn(())<<>>;;&&||"".
+
+       _c_h_a_r _* hhiissttoorryy__nnoo__eexxppaanndd__cchhaarrss
+       The list of characters which inhibit history expansion if found immedi-
+       ately following hhiissttoorryy__eexxppaannssiioonn__cchhaarr.  The  default  is  space,  tab,
+       newline, \\rr, and ==.
+
+       _c_h_a_r _* hhiissttoorryy__sseeaarrcchh__ddeelliimmiitteerr__cchhaarrss
+       The  list  of  additional characters which can delimit a history search
+       string, in addition to space, tab, _: and _? in the case of  a  substring
+       search.  The default is empty.
+
+       _i_n_t hhiissttoorryy__qquuootteess__iinnhhiibbiitt__eexxppaannssiioonn
+       If non-zero, single-quoted words are not scanned for the history expan-
+       sion character.  The default value is 0.
+
+       _r_l___l_i_n_e_b_u_f___f_u_n_c___t _* hhiissttoorryy__iinnhhiibbiitt__eexxppaannssiioonn__ffuunnccttiioonn
+       This should be set to the address of a function that  takes  two  argu-
+       ments:  a  cchhaarr  **  (_s_t_r_i_n_g) and an iinntt index into that string (_i).  It
+       should return a non-zero value if the  history  expansion  starting  at
+       _s_t_r_i_n_g_[_i_]  should  not  be  performed;  zero if the expansion should be
+       done.  It is intended for use by applications like bbaasshh  that  use  the
+       history  expansion character for additional purposes.  By default, this
+       variable is set to NNUULLLL.

+.if t The GNU History Library is Copyright \(co 1989-2011 by the Free Software Foundation, Inc.
+.if n The GNU History Library is Copyright (C) 1989-2011 by the Free Software Foundation, Inc.
+.SH DESCRIPTION
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+.PP
+.SH "HISTORY EXPANSION"
+.PP
+The history library supports a history expansion feature that
+is identical to the history expansion in
+.BR bash.
+This section describes what syntax features are available.
+.PP
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+.PP
+History expansion is usually performed immediately after a complete line
+is read.
+It takes place in two parts.
+The first is to determine which line from the history list
+to use during substitution.
+The second is to select portions of that line for inclusion into
+the current one.
+The line selected from the history is the \fIevent\fP,
+and the portions of that line that are acted upon are \fIwords\fP.
+Various \fImodifiers\fP are available to manipulate the selected words.
+The line is broken into words in the same fashion as \fBbash\fP
+does when reading input,
+so that several words that would otherwise be separated 
+are considered one word when surrounded by quotes (see the
+description of \fBhistory_tokenize()\fP below).
+History expansions are introduced by the appearance of the
+history expansion character, which is \^\fB!\fP\^ by default.
+Only backslash (\^\fB\e\fP\^) and single quotes can quote
+the history expansion character.
+.SS Event Designators
+.PP
+An event designator is a reference to a command line entry in the
+history list.
+Unless the reference is absolute, events are relative to the current
+position in the history list.
+.PP
+.PD 0
+.TP
+.B !
+Start a history substitution, except when followed by a
+.BR blank ,
+newline, = or (.
+.TP
+.B !\fIn\fR
+Refer to command line
+.IR n .
+.TP
+.B !\-\fIn\fR
+Refer to the current command minus
+.IR n .
+.TP
+.B !!
+Refer to the previous command.  This is a synonym for `!\-1'.
+.TP
+.B !\fIstring\fR
+Refer to the most recent command
+preceding the current position in the history list
+starting with
+.IR string .
+.TP
+.B !?\fIstring\fR\fB[?]\fR
+Refer to the most recent command
+preceding the current postition in the history list
+containing
+.IR string .
+The trailing \fB?\fP may be omitted if
+.I string
+is followed immediately by a newline.
+.TP
+.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u
+Quick substitution.  Repeat the last command, replacing
+.I string1
+with
+.IR string2 .
+Equivalent to
+``!!:s/\fIstring1\fP/\fIstring2\fP/''
+(see \fBModifiers\fP below).
+.TP
+.B !#
+The entire command line typed so far.
+.PD
+.SS Word Designators
+.PP
+Word designators are used to select desired words from the event.
+A 
+.B :
+separates the event specification from the word designator.
+It may be omitted if the word designator begins with a
+.BR ^ ,
+.BR $ ,
+.BR * ,
+.BR \- ,
+or
+.BR % .
+Words are numbered from the beginning of the line,
+with the first word being denoted by 0 (zero).
+Words are inserted into the current line separated by single spaces.
+.PP
+.PD 0
+.TP
+.B 0 (zero)
+The zeroth word.  For the shell, this is the command
+word.
+.TP
+.I n
+The \fIn\fRth word.
+.TP
+.B ^
+The first argument.  That is, word 1.
+.TP
+.B $
+The last argument.
+.TP
+.B %
+The word matched by the most recent `?\fIstring\fR?' search.
+.TP
+.I x\fB\-\fPy
+A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'.
+.TP
+.B *
+All of the words but the zeroth.  This is a synonym
+for `\fI1\-$\fP'.  It is not an error to use
+.B *
+if there is just one
+word in the event; the empty string is returned in that case.
+.TP
+.B x*
+Abbreviates \fIx\-$\fP.
+.TP
+.B x\-
+Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word.
+.PD
+.PP
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+.SS Modifiers
+.PP
+After the optional word designator, there may appear a sequence of
+one or more of the following modifiers, each preceded by a `:'.
+.PP
+.PD 0
+.PP
+.TP
+.B h
+Remove a trailing file name component, leaving only the head.
+.TP
+.B t
+Remove all leading file name components, leaving the tail.
+.TP
+.B r
+Remove a trailing suffix of the form \fI.xxx\fP, leaving the
+basename.
+.TP
+.B e
+Remove all but the trailing suffix.
+.TP
+.B p
+Print the new command but do not execute it.
+.TP
+.B q
+Quote the substituted words, escaping further substitutions.
+.TP
+.B x
+Quote the substituted words as with
+.BR q ,
+but break into words at
+.B blanks
+and newlines.
+.TP
+.B s/\fIold\fP/\fInew\fP/
+Substitute
+.I new
+for the first occurrence of
+.I old
+in the event line.  Any delimiter can be used in place of /.  The
+final delimiter is optional if it is the last character of the
+event line.  The delimiter may be quoted in
+.I old
+and
+.I new
+with a single backslash.  If & appears in
+.IR new ,
+it is replaced by
+.IR old .
+A single backslash will quote the &.  If
+.I old
+is null, it is set to the last
+.I old
+substituted, or, if no previous history substitutions took place,
+the last
+.I string
+in a
+.B !?\fIstring\fR\fB[?]\fR
+search.
+.TP
+.B &
+Repeat the previous substitution.
+.TP
+.B g
+Cause changes to be applied over the entire event line.  This is
+used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR')
+or `\fB:&\fP'.  If used with
+`\fB:s\fP', any delimiter can be used
+in place of /, and the final delimiter is optional
+if it is the last character of the event line.
+An \fBa\fP may be used as a synonym for \fBg\fP.
+.TP
+.B G
+Apply the following `\fBs\fP' modifier once to each word in the event line.
+.PD
+.SH "PROGRAMMING WITH HISTORY FUNCTIONS"
+This section describes how to use the History library in other programs.
+.SS Introduction to History
+.PP
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history \fIexpansion\fP function
+is available which provides for a consistent user interface across
+different programs.
+.PP
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are
+identical to
+the history substitution provided by \fBbash\fP.
+.PP
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+.PP
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file
+.FN <readline/history.h>
+in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+.SS History Storage
+.PP
+The history list is an array of history entries.  A history entry is
+declared as follows:
+.PP
+.Vb "typedef void *" histdata_t;
+.PP
+.nf
+typedef struct _hist_entry {
+  char *line;
+  char *timestamp;
+  histdata_t data;
+} HIST_ENTRY;
+.fi
+.PP
+The history list itself might therefore be declared as
+.PP
+.Vb "HIST_ENTRY **" the_history_list;
+.PP
+The state of the History library is encapsulated into a single structure:
+.PP
+.nf
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state {
+  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+  int offset;           /* The location pointer within this array. */
+  int length;           /* Number of elements within this array. */
+  int size;             /* Number of slots allocated to this array. */
+  int flags;
+} HISTORY_STATE;
+.fi
+.PP
+If the flags member includes \fBHS_STIFLED\fP, the history has been
+stifled.
+.SH "History Functions"
+.PP
+This section describes the calling sequence for the various functions
+exported by the GNU History library.
+.SS Initializing History and State Management
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+.Fn1 void using_history void
+Begin a session in which the history functions might be used.  This
+initializes the interactive variables.
+
+.Fn1 "HISTORY_STATE *" history_get_history_state void
+Return a structure describing the current state of the input history.
+
+.Fn1 void history_set_history_state "HISTORY_STATE *state"
+Set the state of the history list according to \fIstate\fP.
+
+.SS History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+.Fn1 void add_history "const char *string"
+Place \fIstring\fP at the end of the history list.  The associated data
+field (if any) is set to \fBNULL\fP.
+
+.Fn1 void add_history_time "const char *string"
+Change the time stamp associated with the most recent history entry to
+\fIstring\fP.
+
+.Fn1 "HIST_ENTRY *" remove_history "int which"
+Remove history entry at offset \fIwhich\fP from the history.  The
+removed element is returned so you can free the line, data,
+and containing structure.
+
+.Fn1 "histdata_t" free_history_entry "HIST_ENTRY *histent"
+Free the history entry \fIhistent\fP and any history library private
+data associated with it.  Returns the application-specific data
+so the caller can dispose of it.
+
+.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data"
+Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP.
+This returns the old entry so the caller can dispose of any
+application-specific data.  In the case
+of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned.
+
+.Fn1 void clear_history "void"
+Clear the history list by deleting all the entries.
+
+.Fn1 void stifle_history "int max"
+Stifle the history list, remembering only the last \fImax\fP entries.
+
+.Fn1 int unstifle_history "void"
+Stop stifling the history.  This returns the previously-set
+maximum number of history entries (as set by \fBstifle_history()\fP).
+history was stifled.  The value is positive if the history was
+stifled, negative if it wasn't.
+
+.Fn1 int history_is_stifled "void"
+Returns non-zero if the history is stifled, zero if it is not.
+
+.SS Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+.Fn1 "HIST_ENTRY **" history_list "void"
+Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the
+current input history.  Element 0 of this list is the beginning of time.
+If there is no history, return \fBNULL\fP.
+
+.Fn1 int where_history "void"
+Returns the offset of the current history element.
+
+.Fn1 "HIST_ENTRY *" current_history "void"
+Return the history entry at the current position, as determined by
+\fBwhere_history()\fP.  If there is no entry there, return a \fBNULL\fP
+pointer.
+
+.Fn1 "HIST_ENTRY *" history_get "int offset"
+Return the history entry at position \fIoffset\fP, starting from
+\fBhistory_base\fP.
+If there is no entry there, or if \fIoffset\fP
+is greater than the history length, return a \fBNULL\fP pointer.
+
+.Fn1 "time_t" history_get_time "HIST_ENTRY *"
+Return the time stamp associated with the history entry passed as the argument.
+
+.Fn1 int history_total_bytes "void"
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+
+.SS Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+.Fn1 int history_set_pos "int pos"
+Set the current history offset to \fIpos\fP, an absolute index
+into the list.
+Returns 1 on success, 0 if \fIpos\fP is less than zero or greater
+than the number of history entries.
+
+.Fn1 "HIST_ENTRY *" previous_history "void"
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry.  If there is no previous entry, return
+a \fBNULL\fP pointer.
+
+.Fn1 "HIST_ENTRY *" next_history "void"
+Move the current history offset forward to the next history entry, and
+return the a pointer to that entry.  If there is no next entry, return
+a \fBNULL\fP pointer.
+
+.SS Searching the History List
+
+These functions allow searching of the history list for entries containing
+a specific string.  Searching may be performed both forward and backward
+from the current history position.  The search may be \fIanchored\fP,
+meaning that the string must match at the beginning of the history entry.
+
+.Fn2 int history_search "const char *string" "int direction"
+Search the history for \fIstring\fP, starting at the current history offset.
+If \fIdirection\fP is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If \fIstring\fP is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+\fIstring\fP was found.  Otherwise, nothing is changed, and a -1 is
+returned.
+
+.Fn2 int history_search_prefix "const char *string" "int direction"
+Search the history for \fIstring\fP, starting at the current history
+offset.  The search is anchored: matching lines must begin with
+\fIstring\fP.  If \fIdirection\fP is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If \fIstring\fP is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+
+.Fn3 int history_search_pos "const char *string" "int direction" "int pos"
+Search for \fIstring\fP in the history list, starting at \fIpos\fP, an
+absolute index into the list.  If \fIdirection\fP is negative, the search
+proceeds backward from \fIpos\fP, otherwise forward.  Returns the absolute
+index of the history element where \fIstring\fP was found, or -1 otherwise.
+
+.SS Managing the History File
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+.Fn1 int read_history "const char *filename"
+Add the contents of \fIfilename\fP to the history list, a line at a time.
+If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP.
+Returns 0 if successful, or \fBerrno\fP if not.
+
+.Fn3 int read_history_range "const char *filename" "int from" "int to"
+Read a range of lines from \fIfilename\fP, adding them to the history list.
+Start reading at line \fIfrom\fP and end at \fIto\fP.
+If \fIfrom\fP is zero, start at the beginning.  If \fIto\fP is less than
+\fIfrom\fP, then read until the end of the file.  If \fIfilename\fP is
+\fBNULL\fP, then read from \fI~/.history\fP.  Returns 0 if successful,
+or \fBerrno\fP if not.
+
+.Fn1 int write_history "const char *filename"
+Write the current history to \fIfilename\fP, overwriting \fIfilename\fP
+if necessary.
+If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP.
+Returns 0 on success, or \fBerrno\fP on a read or write error.
+
+
+.Fn2 int append_history "int nelements" "const char *filename"
+Append the last \fInelements\fP of the history list to \fIfilename\fP.
+If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP.
+Returns 0 on success, or \fBerrno\fP on a read or write error.
+
+.Fn2 int history_truncate_file "const char *filename" "int nlines"
+Truncate the history file \fIfilename\fP, leaving only the last
+\fInlines\fP lines.
+If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated.
+Returns 0 on success, or \fBerrno\fP on failure.
+
+.SS History Expansion
+
+These functions implement history expansion.
+
+.Fn2 int history_expand "char *string" "char **output"
+Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer
+to a string.  Returns:
+.RS
+.PD 0
+.TP
+0
+If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+.TP
+1
+if expansions did take place;
+.TP
+-1
+if there was an error in expansion;
+.TP
+2
+if the returned line should be displayed, but not executed,
+as with the \fB:p\fP modifier.
+.PD
+.RE
+If an error ocurred in expansion, then \fIoutput\fP contains a descriptive
+error message.
+
+.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar"
+Returns the text of the history event beginning at \fIstring\fP +
+\fI*cindex\fP.  \fI*cindex\fP is modified to point to after the event
+specifier.  At function entry, \fIcindex\fP points to the index into
+\fIstring\fP where the history event specification begins.  \fIqchar\fP
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+
+.Fn1 "char **" history_tokenize "const char *string"
+Return an array of tokens parsed out of \fIstring\fP, much as the
+shell might.
+The tokens are split on the characters in the
+\fBhistory_word_delimiters\fP variable,
+and shell quoting conventions are obeyed.
+
+.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string"
+Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP
+arguments present in \fIstring\fP.  Arguments are split using
+\fBhistory_tokenize()\fP.
+
+.SS History Variables
+
+This section describes the externally-visible variables exported by
+the GNU History Library.
+
+.Vb int history_base
+The logical offset of the first entry in the history list.
+
+.Vb int history_length
+The number of entries currently stored in the history list.
+
+.Vb int history_max_entries
+The maximum number of history entries.  This must be changed using
+\fBstifle_history()\fP.
+
+.Vb int history_wite_timestamps
+If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions.  The default value is 0, meaning that
+timestamps are not saved.
+The current timestamp format uses the value of \fIhistory_comment_char\fP
+to delimit timestamp entries in the history file.  If that variable does
+not have a value (the default), timestamps will not be written.
+
+.Vb char history_expansion_char
+The character that introduces a history event.  The default is \fB!\fP.
+Setting this to 0 inhibits history expansion.
+
+.Vb char history_subst_char
+The character that invokes word substitution if found at the start of
+a line.  The default is \fB^\fP.
+
+.Vb char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+
+.Vb "char *" history_word_delimiters
+The characters that separate tokens for \fBhistory_tokenize()\fP.
+The default value is \fB"\ \et\en()<>;&|"\fP.
+
+.Vb "char *" history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following \fBhistory_expansion_char\fP.  The default is space, tab, newline,
+\fB\er\fP, and \fB=\fP.
+
+.Vb "char *" history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, tab, \fI:\fP and \fI?\fP in the case of
+a substring search.  The default is empty.
+
+.Vb int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character.  The default value is 0.
+
+.Vb "rl_linebuf_func_t *" history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a \fBchar *\fP (\fIstring\fP)
+and an \fBint\fP index into that string (\fIi\fP).
+It should return a non-zero value if the history expansion starting at
+\fIstring[i]\fP should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like \fBbash\fP that use the history
+expansion character for additional purposes.
+By default, this variable is set to \fBNULL\fP.

+<H2> 1.1 History Expansion </H2>
+<!--docid::SEC2::-->
+<P>
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by <CODE>csh</CODE>.  This section
+describes the syntax used to manipulate the history information.
+</P><P>
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+</P><P>
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+<EM>event</EM>, and the portions of that line that are acted upon are
+called <EM>words</EM>.  Various <EM>modifiers</EM> are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is <SAMP>`!'</SAMP> by default.

+<!--docid::SEC7::-->
+<P>
+
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+</P><P>
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history <EM>expansion</EM> function
+is available which provides for a consistent user interface across
+different programs.
+</P><P>
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by <CODE>csh</CODE>.
+</P><P>
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+</P><P>
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file <CODE>&#60;readline/history.h&#62;</CODE> in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.

+PREAMBLE
+<P>
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document <EM>free</EM> in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+</P><P>
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+</P><P>
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+</P><P>
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+<P>
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The "Document", below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as "you".  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+</P><P>
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+</P><P>
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+</P><P>
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+</P><P>
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+</P><P>
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not "Transparent" is called "Opaque".
+</P><P>
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
+<FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification.  Examples
+of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
+<FONT SIZE="-1">JPG</FONT>.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
+<FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
+not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
+output purposes only.
+</P><P>
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+</P><P>
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+</P><P>
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+</P><P>
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+</P><P>
+
+<LI>
+VERBATIM COPYING
+<P>
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+</P><P>
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+</P><P>
+
+<LI>
+COPYING IN QUANTITY
+<P>
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+</P><P>
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+</P><P>
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+</P><P>
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+</P><P>
+
+<LI>
+MODIFICATIONS
+<P>
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+</P><P>
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+<P>
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+<P>
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+<P>
+
+<LI>
+Preserve all the copyright notices of the Document.
+<P>
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+<P>
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+<P>
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+<P>
+
+<LI>
+Include an unaltered copy of this License.
+<P>
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+<P>
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+<P>
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+<P>
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+<P>
+
+<LI>
+Delete any section Entitled "Endorsements".  Such a section
+may not be included in the Modified Version.
+<P>
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+<P>
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+<P>
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+</P><P>
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+</P><P>
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+</P><P>
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+</P><P>
+
+<LI>
+COMBINING DOCUMENTS
+<P>
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+</P><P>
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+</P><P>
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications".  You must delete all
+sections Entitled "Endorsements."
+</P><P>
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+<P>
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+</P><P>
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+</P><P>
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+<P>
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+</P><P>
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+</P><P>
+
+<LI>
+TRANSLATION
+<P>
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+</P><P>
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+</P><P>
+
+<LI>
+TERMINATION
+<P>
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+</P><P>
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+</P><P>
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+</P><P>
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+</P><P>
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+<P>
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+</P><P>
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.

+
+1.1 History Expansion
+=====================
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by `csh'.  This section describes the
+syntax used to manipulate the history information.
+
+   History expansions introduce words from the history list into the
+input stream, making it easy to repeat commands, insert the arguments
+to a previous command into the current input line, or fix errors in
+previous commands quickly.
+
+   History expansion takes place in two parts.  The first is to
+determine which line from the history list should be used during
+substitution.  The second is to select portions of that line for
+inclusion into the current one.  The line selected from the history is
+called the "event", and the portions of that line that are acted upon
+are called "words".  Various "modifiers" are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words surrounded by quotes are
+considered one word.  History expansions are introduced by the
+appearance of the history expansion character, which is `!' by default.
+
+* Menu:
+
+* Event Designators::	How to specify which history line to use.
+* Word Designators::	Specifying which words are of interest.
+* Modifiers::		Modifying the results of substitution.
+
+
+File: history.info,  Node: Event Designators,  Next: Word Designators,  Up: History Interaction
+
+1.1.1 Event Designators
+-----------------------
+
+An event designator is a reference to a command line entry in the
+history list.  Unless the reference is absolute, events are relative to
+the current position in the history list.  
+
+`!'
+     Start a history substitution, except when followed by a space, tab,
+     the end of the line, or `='.
+
+`!N'
+     Refer to command line N.
+
+`!-N'
+     Refer to the command N lines back.
+
+`!!'
+     Refer to the previous command.  This is a synonym for `!-1'.
+
+`!STRING'
+     Refer to the most recent command preceding the current position in
+     the history list starting with STRING.
+
+`!?STRING[?]'
+     Refer to the most recent command preceding the current position in
+     the history list containing STRING.  The trailing `?' may be
+     omitted if the STRING is followed immediately by a newline.
+
+`^STRING1^STRING2^'
+     Quick Substitution.  Repeat the last command, replacing STRING1
+     with STRING2.  Equivalent to `!!:s/STRING1/STRING2/'.
+
+`!#'
+     The entire command line typed so far.
+
+
+
+File: history.info,  Node: Word Designators,  Next: Modifiers,  Prev: Event Designators,  Up: History Interaction
+
+1.1.2 Word Designators
+----------------------
+
+Word designators are used to select desired words from the event.  A
+`:' separates the event specification from the word designator.  It may
+be omitted if the word designator begins with a `^', `$', `*', `-', or
+`%'.  Words are numbered from the beginning of the line, with the first
+word being denoted by 0 (zero).  Words are inserted into the current
+line separated by single spaces.
+
+   For example,
+
+`!!'
+     designates the preceding command.  When you type this, the
+     preceding command is repeated in toto.
+
+`!!:$'
+     designates the last argument of the preceding command.  This may be
+     shortened to `!$'.
+
+`!fi:2'
+     designates the second argument of the most recent command starting
+     with the letters `fi'.
+
+   Here are the word designators:
+
+`0 (zero)'
+     The `0'th word.  For many applications, this is the command word.
+
+`N'
+     The Nth word.
+
+`^'
+     The first argument; that is, word 1.
+
+`$'
+     The last argument.
+
+`%'
+     The word matched by the most recent `?STRING?' search.
+
+`X-Y'
+     A range of words; `-Y' abbreviates `0-Y'.
+
+`*'
+     All of the words, except the `0'th.  This is a synonym for `1-$'.
+     It is not an error to use `*' if there is just one word in the
+     event; the empty string is returned in that case.
+
+`X*'
+     Abbreviates `X-$'
+
+`X-'
+     Abbreviates `X-$' like `X*', but omits the last word.
+
+
+   If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+
+File: history.info,  Node: Modifiers,  Prev: Word Designators,  Up: History Interaction
+
+1.1.3 Modifiers
+---------------
+
+After the optional word designator, you can add a sequence of one or
+more of the following modifiers, each preceded by a `:'.
+
+`h'
+     Remove a trailing pathname component, leaving only the head.
+
+`t'
+     Remove all leading pathname components, leaving the tail.
+
+`r'
+     Remove a trailing suffix of the form `.SUFFIX', leaving the
+     basename.
+
+`e'
+     Remove all but the trailing suffix.
+
+`p'
+     Print the new command but do not execute it.
+
+`s/OLD/NEW/'
+     Substitute NEW for the first occurrence of OLD in the event line.
+     Any delimiter may be used in place of `/'.  The delimiter may be
+     quoted in OLD and NEW with a single backslash.  If `&' appears in
+     NEW, it is replaced by OLD.  A single backslash will quote the
+     `&'.  The final delimiter is optional if it is the last character
+     on the input line.
+
+`&'
+     Repeat the previous substitution.
+
+`g'
+`a'
+     Cause changes to be applied over the entire event line.  Used in
+     conjunction with `s', as in `gs/OLD/NEW/', or with `&'.
+
+`G'
+     Apply the following `s' modifier once to each word in the event.

+
+2.1 Introduction to History
+===========================
+
+Many programs read input from the user a line at a time.  The GNU
+History library is able to keep track of those lines, associate
+arbitrary data with each line, and utilize information from previous
+lines in composing new ones.
+
+   The programmer using the History library has available functions for
+remembering lines on a history list, associating arbitrary data with a
+line, removing lines from the list, searching through the list for a
+line containing an arbitrary text string, and referencing any line in
+the list directly.  In addition, a history "expansion" function is
+available which provides for a consistent user interface across
+different programs.
+
+   The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by `csh'.
+
+   If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+   Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file `<readline/history.h>' in any file that uses the History
+library's features.  It supplies extern declarations for all of the
+library's public functions and variables, and declares all of the
+public data structures.
+
+
+File: history.info,  Node: History Storage,  Next: History Functions,  Prev: Introduction to History,  Up: Programming with GNU History
+
+2.2 History Storage
+===================
+
+The history list is an array of history entries.  A history entry is
+declared as follows:
+
+     typedef void *histdata_t;
+
+     typedef struct _hist_entry {
+       char *line;
+       char *timestamp;
+       histdata_t data;
+     } HIST_ENTRY;
+
+   The history list itself might therefore be declared as
+
+     HIST_ENTRY **the_history_list;
+
+   The state of the History library is encapsulated into a single
+structure:
+
+     /*
+      * A structure used to pass around the current state of the history.
+      */
+     typedef struct _hist_state {
+       HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+       int offset;           /* The location pointer within this array. */
+       int length;           /* Number of elements within this array. */
+       int size;             /* Number of slots allocated to this array. */
+       int flags;
+     } HISTORY_STATE;
+
+   If the flags member includes `HS_STIFLED', the history has been
+stifled.

+2.3.1 Initializing History and State Management
+-----------------------------------------------
+
+This section describes functions used to initialize and manage the
+state of the History library when you want to use the history functions
+in your program.
+
+ -- Function: void using_history (void)
+     Begin a session in which the history functions might be used.  This
+     initializes the interactive variables.
+
+ -- Function: HISTORY_STATE * history_get_history_state (void)
+     Return a structure describing the current state of the input
+     history.
+
+ -- Function: void history_set_history_state (HISTORY_STATE *state)
+     Set the state of the history list according to STATE.
+
+
+File: history.info,  Node: History List Management,  Next: Information About the History List,  Prev: Initializing History and State Management,  Up: History Functions
+
+2.3.2 History List Management
+-----------------------------
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+ -- Function: void add_history (const char *string)
+     Place STRING at the end of the history list.  The associated data
+     field (if any) is set to `NULL'.
+
+ -- Function: void add_history_time (const char *string)
+     Change the time stamp associated with the most recent history
+     entry to STRING.
+
+ -- Function: HIST_ENTRY * remove_history (int which)
+     Remove history entry at offset WHICH from the history.  The
+     removed element is returned so you can free the line, data, and
+     containing structure.
+
+ -- Function: histdata_t free_history_entry (HIST_ENTRY *histent)
+     Free the history entry HISTENT and any history library private
+     data associated with it.  Returns the application-specific data so
+     the caller can dispose of it.
+
+ -- Function: HIST_ENTRY * replace_history_entry (int which, const char
+          *line, histdata_t data)
+     Make the history entry at offset WHICH have LINE and DATA.  This
+     returns the old entry so the caller can dispose of any
+     application-specific data.  In the case of an invalid WHICH, a
+     `NULL' pointer is returned.
+
+ -- Function: void clear_history (void)
+     Clear the history list by deleting all the entries.
+
+ -- Function: void stifle_history (int max)
+     Stifle the history list, remembering only the last MAX entries.
+
+ -- Function: int unstifle_history (void)
+     Stop stifling the history.  This returns the previously-set
+     maximum number of history entries (as set by `stifle_history()').
+     The value is positive if the history was stifled, negative if it
+     wasn't.
+
+ -- Function: int history_is_stifled (void)
+     Returns non-zero if the history is stifled, zero if it is not.
+
+
+File: history.info,  Node: Information About the History List,  Next: Moving Around the History List,  Prev: History List Management,  Up: History Functions
+
+2.3.3 Information About the History List
+----------------------------------------
+
+These functions return information about the entire history list or
+individual list entries.
+
+ -- Function: HIST_ENTRY ** history_list (void)
+     Return a `NULL' terminated array of `HIST_ENTRY *' which is the
+     current input history.  Element 0 of this list is the beginning of
+     time.  If there is no history, return `NULL'.
+
+ -- Function: int where_history (void)
+     Returns the offset of the current history element.
+
+ -- Function: HIST_ENTRY * current_history (void)
+     Return the history entry at the current position, as determined by
+     `where_history()'.  If there is no entry there, return a `NULL'
+     pointer.
+
+ -- Function: HIST_ENTRY * history_get (int offset)
+     Return the history entry at position OFFSET, starting from
+     `history_base' (*note History Variables::).  If there is no entry
+     there, or if OFFSET is greater than the history length, return a
+     `NULL' pointer.
+
+ -- Function: time_t history_get_time (HIST_ENTRY *entry)
+     Return the time stamp associated with the history entry ENTRY.
+
+ -- Function: int history_total_bytes (void)
+     Return the number of bytes that the primary history entries are
+     using.  This function returns the sum of the lengths of all the
+     lines in the history.
+
+
+File: history.info,  Node: Moving Around the History List,  Next: Searching the History List,  Prev: Information About the History List,  Up: History Functions
+
+2.3.4 Moving Around the History List
+------------------------------------
+
+These functions allow the current index into the history list to be set
+or changed.
+
+ -- Function: int history_set_pos (int pos)
+     Set the current history offset to POS, an absolute index into the
+     list.  Returns 1 on success, 0 if POS is less than zero or greater
+     than the number of history entries.
+
+ -- Function: HIST_ENTRY * previous_history (void)
+     Back up the current history offset to the previous history entry,
+     and return a pointer to that entry.  If there is no previous
+     entry, return a `NULL' pointer.
+
+ -- Function: HIST_ENTRY * next_history (void)
+     Move the current history offset forward to the next history entry,
+     and return the a pointer to that entry.  If there is no next
+     entry, return a `NULL' pointer.

+
+2.3.5 Searching the History List
+--------------------------------
+
+These functions allow searching of the history list for entries
+containing a specific string.  Searching may be performed both forward
+and backward from the current history position.  The search may be
+"anchored", meaning that the string must match at the beginning of the
+history entry.  
+
+ -- Function: int history_search (const char *string, int direction)
+     Search the history for STRING, starting at the current history
+     offset.  If DIRECTION is less than 0, then the search is through
+     previous entries, otherwise through subsequent entries.  If STRING
+     is found, then the current history index is set to that history
+     entry, and the value returned is the offset in the line of the
+     entry where STRING was found.  Otherwise, nothing is changed, and
+     a -1 is returned.
+
+ -- Function: int history_search_prefix (const char *string, int
+          direction)
+     Search the history for STRING, starting at the current history
+     offset.  The search is anchored: matching lines must begin with
+     STRING.  If DIRECTION is less than 0, then the search is through
+     previous entries, otherwise through subsequent entries.  If STRING
+     is found, then the current history index is set to that entry, and
+     the return value is 0.  Otherwise, nothing is changed, and a -1 is
+     returned.
+
+ -- Function: int history_search_pos (const char *string, int
+          direction, int pos)
+     Search for STRING in the history list, starting at POS, an
+     absolute index into the list.  If DIRECTION is negative, the search
+     proceeds backward from POS, otherwise forward.  Returns the
+     absolute index of the history element where STRING was found, or
+     -1 otherwise.

+
+2.3.6 Managing the History File
+-------------------------------
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+ -- Function: int read_history (const char *filename)
+     Add the contents of FILENAME to the history list, a line at a time.
+     If FILENAME is `NULL', then read from `~/.history'.  Returns 0 if
+     successful, or `errno' if not.
+
+ -- Function: int read_history_range (const char *filename, int from,
+          int to)
+     Read a range of lines from FILENAME, adding them to the history
+     list.  Start reading at line FROM and end at TO.  If FROM is zero,
+     start at the beginning.  If TO is less than FROM, then read until
+     the end of the file.  If FILENAME is `NULL', then read from
+     `~/.history'.  Returns 0 if successful, or `errno' if not.
+
+ -- Function: int write_history (const char *filename)
+     Write the current history to FILENAME, overwriting FILENAME if
+     necessary.  If FILENAME is `NULL', then write the history list to
+     `~/.history'.  Returns 0 on success, or `errno' on a read or write
+     error.
+
+ -- Function: int append_history (int nelements, const char *filename)
+     Append the last NELEMENTS of the history list to FILENAME.  If
+     FILENAME is `NULL', then append to `~/.history'.  Returns 0 on
+     success, or `errno' on a read or write error.
+
+ -- Function: int history_truncate_file (const char *filename, int
+          nlines)
+     Truncate the history file FILENAME, leaving only the last NLINES
+     lines.  If FILENAME is `NULL', then `~/.history' is truncated.
+     Returns 0 on success, or `errno' on failure.
+
+
+File: history.info,  Node: History Expansion,  Prev: Managing the History File,  Up: History Functions
+
+2.3.7 History Expansion
+-----------------------
+
+These functions implement history expansion.
+
+ -- Function: int history_expand (char *string, char **output)
+     Expand STRING, placing the result into OUTPUT, a pointer to a
+     string (*note History Interaction::).  Returns:
+    `0'
+          If no expansions took place (or, if the only change in the
+          text was the removal of escape characters preceding the
+          history expansion character);
+
+    `1'
+          if expansions did take place;
+
+    `-1'
+          if there was an error in expansion;
+
+    `2'
+          if the returned line should be displayed, but not executed,
+          as with the `:p' modifier (*note Modifiers::).
+
+     If an error ocurred in expansion, then OUTPUT contains a
+     descriptive error message.
+
+ -- Function: char * get_history_event (const char *string, int
+          *cindex, int qchar)
+     Returns the text of the history event beginning at STRING +
+     *CINDEX.  *CINDEX is modified to point to after the event
+     specifier.  At function entry, CINDEX points to the index into
+     STRING where the history event specification begins.  QCHAR is a
+     character that is allowed to end the event specification in
+     addition to the "normal" terminating characters.
+
+ -- Function: char ** history_tokenize (const char *string)
+     Return an array of tokens parsed out of STRING, much as the shell
+     might.  The tokens are split on the characters in the
+     HISTORY_WORD_DELIMITERS variable, and shell quoting conventions
+     are obeyed.
+
+ -- Function: char * history_arg_extract (int first, int last, const
+          char *string)
+     Extract a string segment consisting of the FIRST through LAST
+     arguments present in STRING.  Arguments are split using
+     `history_tokenize'.

+
+2.4 History Variables
+=====================
+
+This section describes the externally-visible variables exported by the
+GNU History Library.
+
+ -- Variable: int history_base
+     The logical offset of the first entry in the history list.
+
+ -- Variable: int history_length
+     The number of entries currently stored in the history list.
+
+ -- Variable: int history_max_entries
+     The maximum number of history entries.  This must be changed using
+     `stifle_history()'.
+
+ -- Variable: int history_write_timestamps
+     If non-zero, timestamps are written to the history file, so they
+     can be preserved between sessions.  The default value is 0,
+     meaning that timestamps are not saved.
+
+     The current timestamp format uses the value of HISTORY_COMMENT_CHAR
+     to delimit timestamp entries in the history file.  If that
+     variable does not have a value (the default), timestamps will not
+     be written.
+
+ -- Variable: char history_expansion_char
+     The character that introduces a history event.  The default is `!'.
+     Setting this to 0 inhibits history expansion.
+
+ -- Variable: char history_subst_char
+     The character that invokes word substitution if found at the start
+     of a line.  The default is `^'.
+
+ -- Variable: char history_comment_char
+     During tokenization, if this character is seen as the first
+     character of a word, then it and all subsequent characters up to a
+     newline are ignored, suppressing history expansion for the
+     remainder of the line.  This is disabled by default.
+
+ -- Variable: char * history_word_delimiters
+     The characters that separate tokens for `history_tokenize()'.  The
+     default value is `" \t\n()<>;&|"'.
+
+ -- Variable: char * history_search_delimiter_chars
+     The list of additional characters which can delimit a history
+     search string, in addition to space, TAB, `:' and `?' in the case
+     of a substring search.  The default is empty.
+
+ -- Variable: char * history_no_expand_chars
+     The list of characters which inhibit history expansion if found
+     immediately following HISTORY_EXPANSION_CHAR.  The default is
+     space, tab, newline, carriage return, and `='.
+
+ -- Variable: int history_quotes_inhibit_expansion
+     If non-zero, single-quoted words are not scanned for the history
+     expansion character.  The default value is 0.
+
+ -- Variable: rl_linebuf_func_t * history_inhibit_expansion_function
+     This should be set to the address of a function that takes two
+     arguments: a `char *' (STRING) and an `int' index into that string
+     (I).  It should return a non-zero value if the history expansion
+     starting at STRING[I] should not be performed; zero if the
+     expansion should be done.  It is intended for use by applications
+     like Bash that use the history expansion character for additional
+     purposes.  By default, this variable is set to `NULL'.

+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.
+     We recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it
+     can be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You
+     accept the license if you copy, modify or distribute the work in a
+     way requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in
+     the notice that says that the Document is released under this
+     License.  If a section does not fit the above definition of
+     Secondary then it is not allowed to be designated as Invariant.
+     The Document may contain zero Invariant Sections.  If the Document
+     does not identify any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images
+     composed of pixels) generic paint programs or (for drawings) some
+     widely available drawing editor, and that is suitable for input to
+     text formatters or for automatic translation to a variety of
+     formats suitable for input to text formatters.  A copy made in an
+     otherwise Transparent file format whose markup, or absence of
+     markup, has been arranged to thwart or discourage subsequent
+     modification by readers is not Transparent.  An image format is
+     not Transparent if used for any substantial amount of text.  A
+     copy that is not "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and
+     standard-conforming simple HTML, PostScript or PDF designed for
+     human modification.  Examples of transparent image formats include
+     PNG, XCF and JPG.  Opaque formats include proprietary formats that
+     can be read and edited only by proprietary word processors, SGML or
+     XML for which the DTD and/or processing tools are not generally
+     available, and the machine-generated HTML, PostScript or PDF
+     produced by some word processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow
+     the conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the
+     title equally prominent and visible.  You may add other material
+     on the covers in addition.  Copying with changes limited to the
+     covers, as long as they preserve the title of the Document and
+     satisfy these conditions, can be treated as verbatim copying in
+     other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a
+     machine-readable Transparent copy along with each Opaque copy, or
+     state in or with each Opaque copy a computer-network location from
+     which the general network-using public has access to download
+     using public-standard network protocols a complete Transparent
+     copy of the Document, free of added material.  If you use the
+     latter option, you must take reasonably prudent steps, when you
+     begin distribution of Opaque copies in quantity, to ensure that
+     this Transparent copy will remain thus accessible at the stated
+     location until at least one year after the last time you
+     distribute an Opaque copy (directly or through your agents or
+     retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of
+     copies, to give them a chance to provide you with an updated
+     version of the Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with
+     the Modified Version filling the role of the Document, thus
+     licensing distribution and modification of the Modified Version to
+     whoever possesses a copy of it.  In addition, you must do these
+     things in the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of
+          previous versions (which should, if there were any, be listed
+          in the History section of the Document).  You may use the
+          same title as a previous version if the original publisher of
+          that version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on
+          the Title Page.  If there is no section Entitled "History" in
+          the Document, create one stating the title, year, authors,
+          and publisher of the Document as given on its Title Page,
+          then add an item describing the Modified Version as stated in
+          the previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in
+          the "History" section.  You may omit a network location for a
+          work that was published at least four years before the
+          Document itself, or if the original publisher of the version
+          it refers to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the
+          section all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document,
+          unaltered in their text and in their titles.  Section numbers
+          or the equivalent are not considered part of the section
+          titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option
+     designate some or all of these sections as invariant.  To do this,
+     add their titles to the list of Invariant Sections in the Modified
+     Version's license notice.  These titles must be distinct from any
+     other section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end
+     of the list of Cover Texts in the Modified Version.  Only one
+     passage of Front-Cover Text and one of Back-Cover Text may be
+     added by (or through arrangements made by) any one entity.  If the
+     Document already includes a cover text for the same cover,
+     previously added by you or by arrangement made by the same entity
+     you are acting on behalf of, you may not add another; but you may
+     replace the old one, on explicit permission from the previous
+     publisher that added the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination
+     all of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the
+     documents in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow
+     this License in all other respects regarding verbatim copying of
+     that document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of
+     a storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly
+     and finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from
+     you under this License.  If your rights have been terminated and
+     not permanently reinstated, receipt of a copy of some or all of
+     the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     `http://www.gnu.org/copyleft/'.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If
+     the Document does not specify a version number of this License,
+     you may choose any version ever published (not as a draft) by the
+     Free Software Foundation.  If the Document specifies that a proxy
+     can decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@chapter Programming with GNU History
+
+This chapter describes how to interface programs that you write
+with the @sc{gnu} History Library.
+It should be considered a technical guide.
+For information on the interactive use of @sc{gnu} History, @pxref{Using
+History Interactively}.

+@node Introduction to History
+@section Introduction to History
+
+Many programs read input from the user a line at a time.  The @sc{gnu}
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history @dfn{expansion} function
+is available which provides for a consistent user interface across
+different programs.
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by @code{csh}.
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file @code{<readline/history.h>} in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries.  A history entry is
+declared as follows:
+
+@example
+typedef void *histdata_t;
+
+typedef struct _hist_entry @{
+  char *line;
+  char *timestamp;
+  histdata_t data;
+@} HIST_ENTRY;
+@end example
+
+The history list itself might therefore be declared as
+
+@example
+HIST_ENTRY **the_history_list;
+@end example
+
+The state of the History library is encapsulated into a single structure:
+
+@example
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state @{
+  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+  int offset;           /* The location pointer within this array. */
+  int length;           /* Number of elements within this array. */
+  int size;             /* Number of slots allocated to this array. */
+  int flags;
+@} HISTORY_STATE;
+@end example
+
+If the flags member includes @code{HS_STIFLED}, the history has been
+stifled.
+
+@node History Functions
+@section History Functions
+
+This section describes the calling sequence for the various functions
+exported by the @sc{gnu} History library.
+

+@node Initializing History and State Management
+@subsection Initializing History and State Management
+
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+@deftypefun void using_history (void)

+@deftypefun void history_set_history_state (HISTORY_STATE *state)
+Set the state of the history list according to @var{state}.
+@end deftypefun
+
+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (const char *string)
+Place @var{string} at the end of the history list.  The associated data
+field (if any) is set to @code{NULL}.
+@end deftypefun
+
+@deftypefun void add_history_time (const char *string)
+Change the time stamp associated with the most recent history entry to
+@var{string}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history.  The
+removed element is returned so you can free the line, data,
+and containing structure.
+@end deftypefun
+
+@deftypefun {histdata_t} free_history_entry (HIST_ENTRY *histent)
+Free the history entry @var{histent} and any history library private

+
+@deftypefun void clear_history (void)
+Clear the history list by deleting all the entries.
+@end deftypefun
+
+@deftypefun void stifle_history (int max)
+Stifle the history list, remembering only the last @var{max} entries.
+@end deftypefun
+
+@deftypefun int unstifle_history (void)
+Stop stifling the history.  This returns the previously-set
+maximum number of history entries (as set by @code{stifle_history()}).
+The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled (void)
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+
+@node Information About the History List
+@subsection Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list (void)
+Return a @code{NULL} terminated array of @code{HIST_ENTRY *} which is the
+current input history.  Element 0 of this list is the beginning of time.
+If there is no history, return @code{NULL}.
+@end deftypefun
+

+Returns the offset of the current history element.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} current_history (void)

+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}, starting from
+@code{history_base} (@pxref{History Variables}).
+If there is no entry there, or if @var{offset}

+@end deftypefun
+
+@deftypefun time_t history_get_time (HIST_ENTRY *entry)
+Return the time stamp associated with the history entry @var{entry}.
+@end deftypefun
+
+@deftypefun int history_total_bytes (void)
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+@end deftypefun
+
+@node Moving Around the History List
+@subsection Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+@deftypefun int history_set_pos (int pos)
+Set the current history offset to @var{pos}, an absolute index
+into the list.
+Returns 1 on success, 0 if @var{pos} is less than zero or greater
+than the number of history entries.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} previous_history (void)
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry.  If there is no previous entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} next_history (void)
+Move the current history offset forward to the next history entry, and

+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string.  Searching may be performed both forward and backward
+from the current history position.  The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (const char *string, int direction)
+Search the history for @var{string}, starting at the current history offset.
+If @var{direction} is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found.  Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (const char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset.  The search is anchored: matching lines must begin with
+@var{string}.  If @var{direction} is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+@end deftypefun
+
+@deftypefun int history_search_pos (const char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list.  If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward.  Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (const char *filename)
+Add the contents of @var{filename} to the history list, a line at a time.
+If @var{filename} is @code{NULL}, then read from @file{~/.history}.
+Returns 0 if successful, or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int read_history_range (const char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}.
+If @var{from} is zero, start at the beginning.  If @var{to} is less than
+@var{from}, then read until the end of the file.  If @var{filename} is
+@code{NULL}, then read from @file{~/.history}.  Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (const char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary.
+If @var{filename} is @code{NULL}, then write the history list to
+@file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, const char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+If @var{filename} is @code{NULL}, then append to @file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int history_truncate_file (const char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+If @var{filename} is @code{NULL}, then @file{~/.history} is truncated.
+Returns 0 on success, or @code{errno} on failure.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}).  Returns:
+@table @code
+@item 0
+If no expansions took place (or, if the only change in
+the text was the removal of escape characters preceding the history expansion
+character);
+@item 1
+if expansions did take place;
+@item -1
+if there was an error in expansion;
+@item 2
+if the returned line should be displayed, but not executed,
+as with the @code{:p} modifier (@pxref{Modifiers}).
+@end table
+
+If an error ocurred in expansion, then @var{output} contains a descriptive
+error message.
+@end deftypefun
+
+@deftypefun {char *} get_history_event (const char *string, int *cindex, int qchar)
+Returns the text of the history event beginning at @var{string} +
+@var{*cindex}.  @var{*cindex} is modified to point to after the event
+specifier.  At function entry, @var{cindex} points to the index into
+@var{string} where the history event specification begins.  @var{qchar}
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+@end deftypefun
+
+@deftypefun {char **} history_tokenize (const char *string)
+Return an array of tokens parsed out of @var{string}, much as the
+shell might.  The tokens are split on the characters in the
+@var{history_word_delimiters} variable,
+and shell quoting conventions are obeyed.
+@end deftypefun
+
+@deftypefun {char *} history_arg_extract (int first, int last, const char *string)
+Extract a string segment consisting of the @var{first} through @var{last}
+arguments present in @var{string}.  Arguments are split using
+@code{history_tokenize}.
+@end deftypefun
+
+@node History Variables
+@section History Variables
+
+This section describes the externally-visible variables exported by
+the @sc{gnu} History Library.

+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}.  The default is space, tab, newline,
+carriage return, and @samp{=}.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character.  The default value is 0.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string})
+and an @code{int} index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to @code{NULL}.

+@cindex command history
+@cindex history list
+
+When the @option{-o history} option to the @code{set} builtin
+is enabled (@pxref{The Set Builtin}),
+the shell provides access to the @dfn{command history},
+the list of commands previously typed.
+The value of the @env{HISTSIZE} shell variable is used as the
+number of commands to save in a history list.
+The text of the last @env{$HISTSIZE}
+commands (default 500) is saved.
+The shell stores each command in the history list prior to
+parameter and variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@env{HISTIGNORE} and @env{HISTCONTROL}.
+
+When the shell starts up, the history is initialized from the
+file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
+The file named by the value of @env{HISTFILE} is truncated, if
+necessary, to contain no more than the number of lines specified by
+the value of the @env{HISTFILESIZE} variable.
+When an interactive shell exits, the last
+@env{$HISTSIZE} lines are copied from the history list to the file
+named by @env{$HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @env{HISTFILE}
+is unset, or if the history file is unwritable, the history is
+not saved.  After saving the history, the history file is truncated
+to contain no more than @env{$HISTFILESIZE}
+lines.  If @env{HISTFILESIZE} is not set, no truncation is performed.
+
+If the @env{HISTTIMEFORMAT} is set, the time stamp information
+associated with each history entry is written to the history file,
+marked with the history comment character.
+When the history file is read, lines beginning with the history
+comment character followed immediately by a digit are interpreted
+as timestamps for the previous history line.
+
+The builtin command @code{fc} may be used to list or edit and re-execute
+a portion of the history list.
+The @code{history} builtin may be used to display or modify the history
+list and manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list (@pxref{Commands For History}).
+
+The shell allows control over which commands are saved on the history
+list.  The @env{HISTCONTROL} and @env{HISTIGNORE}
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The @code{cmdhist}
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The @code{lithist}
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.
+The @code{shopt} builtin is used to set these options.
+@xref{Bash Builtins}, for a description of @code{shopt}.
+
+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands which manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@btindex fc
+@example
+@code{fc [-e @var{ename}] [-lnr] [@var{first}] [@var{last}]}
+@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
+@end example
+
+Fix Command.  In the first form, a range of commands from @var{first} to
+@var{last} is selected from the history list.  Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).  If @var{last} is not specified it is set to
+@var{first}.  If @var{first} is not specified it is set to the previous
+command for editing and @minus{}16 for listing.  If the @option{-l} flag is
+given, the commands are listed on standard output.  The @option{-n} flag
+suppresses the command numbers when listing.  The @option{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @env{FCEDIT} variable if set, or the value of the
+@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).
+
+@item history
+@btindex history
+@example
+history [@var{n}]
+history -c
+history -d @var{offset}
+history [-anrw] [@var{filename}]
+history -ps @var{arg}
+@end example
+
+With no options, display the history list with line numbers.
+Lines prefixed with a @samp{*} have been modified.
+An argument of @var{n} lists only the last @var{n} lines.
+If the shell variable @env{HISTTIMEFORMAT} is set and not null,
+it is used as a format string for @var{strftime} to display
+the time stamp associated with each displayed history entry.
+No intervening blank is printed between the formatted time stamp
+and the history line.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -d @var{offset}
+Delete the history entry at position @var{offset}.
+@var{offset} should be specified as it appears when the history is
+displayed.
+
+@item -a
+Append the new
+history lines (history lines entered since the beginning of the
+current Bash session) to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -r
+Read the current history file and append its contents to
+the history list.
+
+@item -w
+Write out the current history to the history file.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@end table
+
+When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
+used, if @var{filename}
+is given, then it is used as the history file.  If not, then
+the value of the @env{HISTFILE} variable is used.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}.  This section
+describes the syntax used to manipulate the history information.
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+@dfn{event}, and the portions of that line that are acted upon are
+called @dfn{words}.  Various @dfn{modifiers} are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is @samp{!} by default.
+@ifset BashFeatures
+Only @samp{\} and @samp{'} may be used to escape the history expansion
+character.
+@end ifset
+
+@ifset BashFeatures
+Several shell options settable with the @code{shopt}
+builtin (@pxref{Bash Builtins}) may be used to tailor
+the behavior of history expansion.  If the
+@code{histverify} shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the @code{histreedit}
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The @option{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @option{-s} option to the @code{history} builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+
+The shell allows control of the various characters used by the
+history expansion mechanism with the @code{histchars} variable,
+as explained above (@pxref{Bash Variables}).  The shell uses
+the history comment character to mark history timestamps when
+writing the history file.

+@subsection Event Designators
+@cindex event designators
+
+An event designator is a reference to a command line entry in the

+Unless the reference is absolute, events are relative to the current
+position in the history list.
+@cindex history events
+
+@table @asis

+@end ifclear
+
+@item @code{!@var{n}}
+Refer to command line @var{n}.
+
+@item @code{!-@var{n}}
+Refer to the command @var{n} lines back.
+
+@item @code{!!}
+Refer to the previous command.  This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command
+preceding the current position in the history list
+starting with @var{string}.
+
+@item @code{!?@var{string}[?]}
+Refer to the most recent command
+preceding the current position in the history list
+containing @var{string}.
+The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution.  Repeat the last command, replacing @var{string1}
+with @var{string2}.  Equivalent to
+@code{!!:s/@var{string1}/@var{string2}/}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator.  It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}.  Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero).  Words are
+inserted into the current line separated by single spaces.
+
+@need 0.75
+For example,
+
+@table @code
+@item !!
+designates the preceding command.  When you type this, the preceding
+command is repeated in toto.
+
+@item !!:$
+designates the last argument of the preceding command.  This may be
+shortened to @code{!$}.
+
+@item !fi:2
+designates the second argument of the most recent command starting with
+the letters @code{fi}.
+@end table
+
+@need 0.75
+Here are the word designators:
+ 
+@table @code
+
+@item 0 (zero)
+The @code{0}th word.  For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The word matched by the most recent @samp{?@var{string}?} search.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th.  This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading pathname components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line.  Any delimiter may be used in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash.  If @samp{&} appears in @var{new},
+it is replaced by @var{old}.  A single backslash will quote
+the @samp{&}.  The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+@itemx a
+Cause changes to be applied over the entire event line.  Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.
+
+@item G
+Apply the following @samp{s} modifier once to each word in the event.

+       free it when  finished.   The  line  returned  has  the  final  newline
+       removed, so only the text of the line remains.
+
+       rreeaaddlliinnee  offers  editing  capabilities  while the user is entering the
+       line.  By default, the line editing commands are similar  to  those  of
+       emacs.  A vi-style line editing interface is also available.
+
+       This  manual  page describes only the most basic use of rreeaaddlliinnee.  Much
+       more functionality is available; see _T_h_e _G_N_U _R_e_a_d_l_i_n_e _L_i_b_r_a_r_y  and  _T_h_e
+       _G_N_U _H_i_s_t_o_r_y _L_i_b_r_a_r_y for additional information.
+
+RREETTUURRNN VVAALLUUEE
+       rreeaaddlliinnee  returns  the text of the line read.  A blank line returns the
+       empty string.  If EEOOFF is encountered while reading a line, and the line
+       is  empty,  NNUULLLL is returned.  If an EEOOFF is read with a non-empty line,
+       it is treated as a newline.
+
+NNOOTTAATTIIOONN
+       An Emacs-style notation is used to denote keystrokes.  Control keys are
+       denoted  by C-_k_e_y, e.g., C-n means Control-N.  Similarly, _m_e_t_a keys are
+       denoted by M-_k_e_y, so M-x means Meta-X.  (On keyboards  without  a  _m_e_t_a
+       key,  M-_x means ESC _x, i.e., press the Escape key then the _x key.  This
+       makes ESC the _m_e_t_a _p_r_e_f_i_x.  The combination M-C-_x means  ESC-Control-_x,
+       or  press the Escape key then hold the Control key while pressing the _x
+       key.)
+
+       Readline commands may be given numeric _a_r_g_u_m_e_n_t_s, which normally act as
+       a  repeat  count.   Sometimes,  however, it is the sign of the argument
+       that is significant.  Passing a negative argument  to  a  command  that
+       acts  in the forward direction (e.g., kkiillll--lliinnee) causes that command to
+       act in a backward direction.  Commands whose  behavior  with  arguments
+       deviates from this are noted.
+
+       When  a command is described as _k_i_l_l_i_n_g text, the text deleted is saved
+       for possible future retrieval (_y_a_n_k_i_n_g).  The killed text is saved in a
+       _k_i_l_l _r_i_n_g.  Consecutive kills cause the text to be accumulated into one
+       unit, which can be yanked all at once.  Commands which do not kill text
+       separate the chunks of text on the kill ring.
+
+IINNIITTIIAALLIIZZAATTIIOONN FFIILLEE
+       Readline  is  customized  by putting commands in an initialization file
+       (the _i_n_p_u_t_r_c file).  The name of this file is taken from the  value  of
+       the  IINNPPUUTTRRCC  environment  variable.   If  that  variable is unset, the
+       default is _~_/_._i_n_p_u_t_r_c.  If that file  does not exist or cannot be read,
+       the  ultimate  default  is _/_e_t_c_/_i_n_p_u_t_r_c.  When a program which uses the
+       readline library starts up, the init file is read, and the key bindings
+       and  variables  are set.  There are only a few basic constructs allowed
+       in the readline init file.  Blank lines are ignored.   Lines  beginning
+       with  a  ## are comments.  Lines beginning with a $$ indicate conditional
+       constructs.  Other lines denote key  bindings  and  variable  settings.
+       Each  program using this library may add its own commands and bindings.
+
+       For example, placing
+
+              M-Control-u: universal-argument
+       or
+              C-Meta-u: universal-argument
+
+       into the _i_n_p_u_t_r_c would make M-C-u execute the readline command  _u_n_i_v_e_r_-
+       _s_a_l_-_a_r_g_u_m_e_n_t.
+
+       The  following symbolic character names are recognized while processing
+       key bindings: _D_E_L, _E_S_C, _E_S_C_A_P_E,  _L_F_D,  _N_E_W_L_I_N_E,  _R_E_T,  _R_E_T_U_R_N,  _R_U_B_O_U_T,
+       _S_P_A_C_E, _S_P_C, and _T_A_B.
+
+       In  addition  to  command  names, readline allows keys to be bound to a
+       string that is inserted when the key is pressed (a _m_a_c_r_o).
+
+
+   KKeeyy BBiinnddiinnggss
+       The syntax for controlling key bindings in the _i_n_p_u_t_r_c file is  simple.
+       All  that is required is the name of the command or the text of a macro
+       and a key sequence to which it should be bound. The name may be  speci-
+       fied in one of two ways: as a symbolic key name, possibly with _M_e_t_a_- or
+       _C_o_n_t_r_o_l_- prefixes, or as a key sequence.  The name and key sequence are
+       separated  by a colon.  There can be no whitespace between the name and
+       the colon.
+
+       When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, _k_e_y_n_a_m_e is the name
+       of a key spelled out in English.  For example:
+
+              Control-u: universal-argument
+              Meta-Rubout: backward-kill-word
+              Control-o: "> output"
+
+       In  the above example, _C_-_u is bound to the function uunniivveerrssaall--aarrgguummeenntt,
+       _M_-_D_E_L is bound to the function bbaacckkwwaarrdd--kkiillll--wwoorrdd, and _C_-_o is bound  to
+       run  the macro expressed on the right hand side (that is, to insert the
+       text ``> output'' into the line).
+
+       In the second form, ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n_-_n_a_m_e  or  _m_a_c_r_o,  kkeeyysseeqq  differs
+       from  kkeeyynnaammee above in that strings denoting an entire key sequence may
+       be specified by placing the sequence within double  quotes.   Some  GNU
+       Emacs  style  key escapes can be used, as in the following example, but
+       the symbolic character names are not recognized.
+
+              "\C-u": universal-argument
+              "\C-x\C-r": re-read-init-file
+              "\e[11~": "Function Key 1"
+
+       In this example, _C_-_u is again bound to the function uunniivveerrssaall--aarrgguummeenntt.
+       _C_-_x  _C_-_r is bound to the function rree--rreeaadd--iinniitt--ffiillee, and _E_S_C _[ _1 _1 _~ is
+       bound to insert the text ``Function Key 1''.
+
+       The full set of GNU Emacs style escape sequences available when  speci-
+       fying key sequences is
+              \\CC--    control prefix
+              \\MM--    meta prefix
+              \\ee     an escape character
+              \\\\     backslash
+              \\""     literal ", a double quote
+              \\''     literal ', a single quote
+
+       In  addition  to  the GNU Emacs style escape sequences, a second set of
+       backslash escapes is available:
+              \\aa     alert (bell)
+              \\bb     backspace
+              \\dd     delete
+              \\ff     form feed
+              \\nn     newline
+              \\rr     carriage return
+              \\tt     horizontal tab
+              \\vv     vertical tab
+              \\_n_n_n   the eight-bit character whose value is  the  octal  value
+                     _n_n_n (one to three digits)
+              \\xx_H_H   the  eight-bit  character  whose value is the hexadecimal
+                     value _H_H (one or two hex digits)
+
+       When entering the text of a macro, single or double  quotes  should  be
+       used  to indicate a macro definition.  Unquoted text is assumed to be a
+       function name.  In the macro  body,  the  backslash  escapes  described
+       above  are  expanded.   Backslash will quote any other character in the
+       macro text, including " and '.
+
+       BBaasshh allows the current readline key bindings to be displayed or  modi-
+       fied  with  the bbiinndd builtin command.  The editing mode may be switched
+       during interactive use by using the --oo option to the sseett  builtin  com-
+       mand.   Other  programs  using this library provide similar mechanisms.
+       The _i_n_p_u_t_r_c file may be edited and re-read if a program does  not  pro-
+       vide any other means to incorporate new bindings.
+
+   VVaarriiaabblleess
+       Readline has variables that can be used to further customize its behav-
+       ior.  A variable may be set in the _i_n_p_u_t_r_c file with a statement of the
+       form
+
+              sseett _v_a_r_i_a_b_l_e_-_n_a_m_e _v_a_l_u_e
+
+       Except  where  noted,  readline variables can take the values OOnn or OOffff
+       (without regard to case).  Unrecognized  variable  names  are  ignored.
+       When  a variable value is read, empty or null values, "on" (case-insen-
+       sitive), and "1" are equivalent to OOnn.  All other values are equivalent
+       to OOffff.  The variables and their default values are:
+
+       bbeellll--ssttyyllee ((aauuddiibbllee))
+              Controls  what  happens when readline wants to ring the terminal
+              bell.  If set to nnoonnee, readline never rings the bell.  If set to
+              vviissiibbllee,  readline  uses a visible bell if one is available.  If
+              set to aauuddiibbllee, readline attempts to ring the terminal's bell.
+       bbiinndd--ttttyy--ssppeecciiaall--cchhaarrss ((OOnn))
+              If set to OOnn, readline attempts to bind the  control  characters
+              treated specially by the kernel's terminal driver to their read-
+              line equivalents.
+       ccoommmmeenntt--bbeeggiinn ((````##''''))
+              The string that is inserted in vvii mode when  the  iinnsseerrtt--ccoommmmeenntt
+              command is executed.  This command is bound to MM--## in emacs mode
+              and to ## in vi command mode.
+       ccoommpplleettiioonn--ddiissppllaayy--wwiiddtthh ((--11))
+              The number of screen columns used to  display  possible  matches
+              when  performing completion.  The value is ignored if it is less
+              than 0 or greater than the terminal screen width.  A value of  0
+              will  cause  matches  to be displayed one per line.  The default
+              value is -1.
+       ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff))
+              If set to OOnn, readline performs filename matching and completion
+              in a case-insensitive fashion.
+       ccoommpplleettiioonn--mmaapp--ccaassee ((OOffff))
+              If  set  to  OOnn, and ccoommpplleettiioonn--iiggnnoorree--ccaassee is enabled, readline
+              treats hyphens (_-) and underscores (__) as equivalent  when  per-
+              forming case-insensitive filename matching and completion.
+       ccoommpplleettiioonn--pprreeffiixx--ddiissppllaayy--lleennggtthh ((00))
+              The  length in characters of the common prefix of a list of pos-
+              sible completions that is displayed without modification.   When
+              set  to  a  value greater than zero, common prefixes longer than
+              this value are replaced with an ellipsis when displaying  possi-
+              ble completions.
+       ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000))
+              This  determines when the user is queried about viewing the num-
+              ber of possible completions generated  by  the  ppoossssiibbllee--ccoommppllee--
+              ttiioonnss  command.  It may be set to any integer value greater than
+              or equal to zero.  If the  number  of  possible  completions  is
+              greater than or equal to the value of this variable, the user is
+              asked whether or not he wishes to view them; otherwise they  are
+              simply listed on the terminal.  A negative value causes readline
+              to never ask.
+       ccoonnvveerrtt--mmeettaa ((OOnn))
+              If set to OOnn, readline will convert characters with  the  eighth
+              bit set to an ASCII key sequence by stripping the eighth bit and
+              prefixing it with an escape character (in effect,  using  escape
+              as the _m_e_t_a _p_r_e_f_i_x).
+       ddiissaabbllee--ccoommpplleettiioonn ((OOffff))
+              If set to OOnn, readline will inhibit word completion.  Completion
+              characters will be inserted into the line as if  they  had  been
+              mapped to sseellff--iinnsseerrtt.
+       eeddiittiinngg--mmooddee ((eemmaaccss))
+              Controls whether readline begins with a set of key bindings sim-
+              ilar to _E_m_a_c_s or _v_i.  eeddiittiinngg--mmooddee can be set to either eemmaaccss or
+              vvii.
+       eecchhoo--ccoonnttrrooll--cchhaarraacctteerrss ((OOnn))
+              When  set to OOnn, on operating systems that indicate they support
+              it, readline echoes a character corresponding to a signal gener-
+              ated from the keyboard.
+       eennaabbllee--kkeeyyppaadd ((OOffff))
+              When set to OOnn, readline will try to enable the application key-
+              pad when it is called.  Some systems need  this  to  enable  the
+              arrow keys.
+       eennaabbllee--mmeettaa--kkeeyy ((OOnn))
+              When  set  to  OOnn, readline will try to enable any meta modifier
+              key the terminal claims to support when it is called.   On  many
+              terminals, the meta key is used to send eight-bit characters.
+       eexxppaanndd--ttiillddee ((OOffff))
+              If  set  to  OOnn,  tilde  expansion  is  performed  when readline
+              attempts word completion.
+       hhiissttoorryy--pprreesseerrvvee--ppooiinntt ((OOffff))
+              If set to OOnn, the history code attempts to place  point  at  the
+              same  location on each history line retrieved with pprreevviioouuss--hhiiss--
+              ttoorryy or nneexxtt--hhiissttoorryy.
+       hhiissttoorryy--ssiizzee ((00))
+              Set the maximum number of history entries saved in  the  history
+              list.  If set to zero, the number of entries in the history list
+              is not limited.
+       hhoorriizzoonnttaall--ssccrroollll--mmooddee ((OOffff))
+              When set to OOnn, makes readline use a single  line  for  display,
+              scrolling the input horizontally on a single screen line when it
+              becomes longer than the screen width rather than wrapping  to  a
+              new line.
+       iinnppuutt--mmeettaa ((OOffff))
+              If  set to OOnn, readline will enable eight-bit input (that is, it
+              will not clear the eighth  bit  in  the  characters  it  reads),
+              regardless of what the terminal claims it can support.  The name
+              mmeettaa--ffllaagg is a synonym for this variable.
+       iisseeaarrcchh--tteerrmmiinnaattoorrss ((````CC--[[ CC--JJ''''))
+              The string of characters that should  terminate  an  incremental
+              search  without  subsequently  executing the character as a com-
+              mand.  If this variable has not been given a value, the  charac-
+              ters _E_S_C and _C_-_J will terminate an incremental search.
+       kkeeyymmaapp ((eemmaaccss))
+              Set  the current readline keymap.  The set of legal keymap names
+              is _e_m_a_c_s_, _e_m_a_c_s_-_s_t_a_n_d_a_r_d_, _e_m_a_c_s_-_m_e_t_a_, _e_m_a_c_s_-_c_t_l_x_,  _v_i_,  _v_i_-_m_o_v_e_,
+              _v_i_-_c_o_m_m_a_n_d,  and  _v_i_-_i_n_s_e_r_t.   _v_i  is  equivalent to _v_i_-_c_o_m_m_a_n_d;
+              _e_m_a_c_s is equivalent to _e_m_a_c_s_-_s_t_a_n_d_a_r_d.   The  default  value  is
+              _e_m_a_c_s.   The  value  of  eeddiittiinngg--mmooddee  also  affects the default
+              keymap.
+       mmaarrkk--ddiirreeccttoorriieess ((OOnn))
+              If set to OOnn, completed directory names have a slash appended.
+       mmaarrkk--mmooddiiffiieedd--lliinneess ((OOffff))
+              If set to OOnn, history lines that have  been  modified  are  dis-

+       mmaarrkk--ssyymmlliinnkkeedd--ddiirreeccttoorriieess ((OOffff))
+              If set to OOnn, completed names which are symbolic links to direc-
+              tories  have  a  slash  appended  (subject  to  the   value   of
+              mmaarrkk--ddiirreeccttoorriieess).
+       mmaattcchh--hhiiddddeenn--ffiilleess ((OOnn))
+              This  variable,  when  set to OOnn, causes readline to match files
+              whose names begin with a  `.'  (hidden  files)  when  performing
+              filename  completion.   If  set  to OOffff, the leading `.' must be
+              supplied by the user in the filename to be completed.
+       mmeennuu--ccoommpplleettee--ddiissppllaayy--pprreeffiixx ((OOffff))
+              If set to OOnn, menu completion displays the common prefix of  the

+              through the list.
+       oouuttppuutt--mmeettaa ((OOffff))
+              If set to OOnn, readline will display characters with  the  eighth
+              bit set directly rather than as a meta-prefixed escape sequence.
+       ppaaggee--ccoommpplleettiioonnss ((OOnn))
+              If set to OOnn, readline uses an internal _m_o_r_e-like pager to  dis-
+              play a screenful of possible completions at a time.
+       pprriinntt--ccoommpplleettiioonnss--hhoorriizzoonnttaallllyy ((OOffff))
+              If  set  to  OOnn,  readline will display completions with matches
+              sorted horizontally in alphabetical order, rather than down  the
+              screen.
+       rreevveerrtt--aallll--aatt--nneewwlliinnee ((OOffff))
+              If  set  to  OOnn, readline will undo all changes to history lines
+              before returning when aacccceepptt--lliinnee is executed.  By default, his-

+              This  alters the default behavior of the completion functions in
+              a fashion similar to sshhooww--aallll--iiff--aammbbiigguuoouuss.  If set to OOnn, words
+              which  have more than one possible completion without any possi-
+              ble partial completion (the possible completions don't  share  a
+              common  prefix)  cause  the  matches  to  be  listed immediately
+              instead of ringing the bell.
+       sskkiipp--ccoommpplleetteedd--tteexxtt ((OOffff))
+              If set to OOnn, this alters the default completion  behavior  when
+              inserting  a  single match into the line.  It's only active when
+              performing completion in the middle  of  a  word.   If  enabled,
+              readline  does  not  insert  characters from the completion that
+              match characters after point in the  word  being  completed,  so
+              portions of the word following the cursor are not duplicated.
+       vviissiibbllee--ssttaattss ((OOffff))
+              If  set to OOnn, a character denoting a file's type as reported by
+              _s_t_a_t(2) is appended to the filename when listing  possible  com-
+              pletions.
+
+   CCoonnddiittiioonnaall CCoonnssttrruuccttss
+       Readline  implements  a  facility  similar in spirit to the conditional
+       compilation features of the C preprocessor which  allows  key  bindings
+       and  variable  settings  to be performed as the result of tests.  There
+       are four parser directives used.
+
+       $$iiff    The $$iiff construct allows bindings to be made based on the  edit-
+              ing  mode,  the  terminal  being  used, or the application using
+              readline.  The text of the test extends to the end of the  line;
+              no characters are required to isolate it.
+
+              mmooddee   The  mmooddee==  form  of  the  $$iiff  directive is used to test
+                     whether readline is in emacs or vi  mode.   This  may  be
+                     used  in  conjunction  with  the  sseett kkeeyymmaapp command, for
+                     instance, to  set  bindings  in  the  _e_m_a_c_s_-_s_t_a_n_d_a_r_d  and
+                     _e_m_a_c_s_-_c_t_l_x  keymaps  only  if readline is starting out in
+                     emacs mode.
+
+              tteerrmm   The tteerrmm== form may be used to  include  terminal-specific
+                     key bindings, perhaps to bind the key sequences output by
+                     the terminal's function keys.  The word on the right side
+                     of  the == is tested against the full name of the terminal
+                     and the portion of the terminal name before the first  --.
+                     This  allows  _s_u_n  to  match  both  _s_u_n  and _s_u_n_-_c_m_d, for
+                     instance.
+
+              aapppplliiccaattiioonn
+                     The aapppplliiccaattiioonn construct is used to include application-
+                     specific  settings.   Each  program  using  the  readline
+                     library sets the _a_p_p_l_i_c_a_t_i_o_n _n_a_m_e, and an  initialization
+                     file can test for a particular value.  This could be used
+                     to bind key sequences to functions useful for a  specific
+                     program.   For instance, the following command adds a key
+                     sequence that quotes the  current  or  previous  word  in
+                     bbaasshh:
+
+                     $$iiff Bash
+                     # Quote the current or previous word
+                     "\C-xq": "\eb\"\ef\""
+                     $$eennddiiff
+
+       $$eennddiiff This command, as seen in the previous example, terminates an $$iiff
+              command.
+
+       $$eellssee  Commands in this branch of the $$iiff directive are executed if the
+              test fails.
+
+       $$iinncclluuddee
+              This  directive takes a single filename as an argument and reads
+              commands and bindings from that file.  For example, the  follow-
+              ing directive would read _/_e_t_c_/_i_n_p_u_t_r_c:
+
+              $$iinncclluuddee  _/_e_t_c_/_i_n_p_u_t_r_c
+
+SSEEAARRCCHHIINNGG
+       Readline  provides  commands  for searching through the command history
+       for lines containing a specified string.  There are two  search  modes:
+       _i_n_c_r_e_m_e_n_t_a_l and _n_o_n_-_i_n_c_r_e_m_e_n_t_a_l.
+
+       Incremental  searches  begin  before  the  user has finished typing the
+       search string.  As each character of the search string is typed,  read-
+       line displays the next entry from the history matching the string typed
+       so far.  An incremental search requires  only  as  many  characters  as
+       needed  to  find  the desired history entry.  To search backward in the
+       history for a particular string, type CC--rr.  Typing CC--ss searches forward
+       through  the  history.   The  characters  present  in  the value of the
+       iisseeaarrcchh--tteerrmmiinnaattoorrss variable  are  used  to  terminate  an  incremental
+       search.   If that variable has not been assigned a value the _E_s_c_a_p_e and
+       CC--JJ characters will terminate an incremental search.  CC--GG will abort an
+       incremental  search  and restore the original line.  When the search is
+       terminated, the history entry containing the search string becomes  the
+       current line.
+
+       To  find other matching entries in the history list, type CC--ss or CC--rr as
+       appropriate.  This will search backward or forward in the  history  for
+       the  next  line matching the search string typed so far.  Any other key
+       sequence bound to a readline command will terminate the search and exe-
+       cute  that  command.  For instance, a newline will terminate the search
+       and accept the line, thereby executing the  command  from  the  history
+       list.  A movement command will terminate the search, make the last line
+       found the current line, and begin editing.
+
+       Non-incremental searches read the entire search string before  starting
+       to  search  for matching history lines.  The search string may be typed
+       by the user or be part of the contents of the current line.

+              Insert the first argument to the previous command  (usually  the
+              second word on the previous line) at point.  With an argument _n,
+              insert the _nth word from the previous command (the words in  the
+              previous  command  begin  with  word  0).   A  negative argument
+              inserts the _nth word from the end of the previous command.  Once
+              the  argument _n is computed, the argument is extracted as if the
+              "!_n" history expansion had been specified.

+              move  back through the history list, inserting the last word (or
+              the word specified by the argument to the first  call)  of  each
+              line in turn.  Any numeric argument supplied to these successive
+              calls determines the direction to move through the  history.   A
+              negative  argument  switches  the  direction through the history
+              (back or forward).  The history expansion facilities are used to
+              extract  the last argument, as if the "!$" history expansion had

+       ddiiggiitt--aarrgguummeenntt ((MM--00,, MM--11,, ......,, MM----))
+              Add this digit to the argument already accumulating, or start  a
+              new argument.  M-- starts a negative argument.
+       uunniivveerrssaall--aarrgguummeenntt
+              This  is another way to specify an argument.  If this command is
+              followed by one or more digits, optionally with a leading  minus
+              sign,  those digits define the argument.  If the command is fol-
+              lowed by digits, executing  uunniivveerrssaall--aarrgguummeenntt  again  ends  the
+              numeric  argument, but is otherwise ignored.  As a special case,
+              if this command is immediately followed by a character  that  is
+              neither  a  digit or minus sign, the argument count for the next
+              command is multiplied by four.  The argument count is  initially
+              one,  so  executing this function the first time makes the argu-
+              ment count four, a second time makes the argument count sixteen,
+              and so on.
+
+   CCoommpplleettiinngg
+       ccoommpplleettee ((TTAABB))
+              Attempt  to  perform  completion  on the text before point.  The
+              actual completion performed is application-specific.  BBaasshh,  for
+              instance,  attempts  completion  treating the text as a variable
+              (if the text begins with $$), username (if the text  begins  with
+              ~~),  hostname (if the text begins with @@), or command (including
+              aliases and functions) in turn.  If none  of  these  produces  a
+              match,  filename  completion  is  attempted.   GGddbb, on the other
+              hand, allows completion of program functions and variables,  and
+              only attempts filename completion under certain circumstances.
+       ppoossssiibbllee--ccoommpplleettiioonnss ((MM--??))
+              List  the  possible  completions of the text before point.  When
+              displaying completions, readline sets the number of columns used
+              for  display to the value of ccoommpplleettiioonn--ddiissppllaayy--wwiiddtthh, the value
+              of the environment variable CCOOLLUUMMNNSS, or  the  screen  width,  in
+              that order.
+       iinnsseerrtt--ccoommpplleettiioonnss ((MM--**))
+              Insert  all completions of the text before point that would have
+              been generated by ppoossssiibbllee--ccoommpplleettiioonnss.
+       mmeennuu--ccoommpplleettee
+              Similar to ccoommpplleettee, but replaces the word to be completed  with
+              a  single match from the list of possible completions.  Repeated
+              execution of mmeennuu--ccoommpplleettee steps through the  list  of  possible
+              completions,  inserting  each  match in turn.  At the end of the
+              list of completions, the bell is rung (subject to the setting of
+              bbeellll--ssttyyllee) and the original text is restored.  An argument of _n
+              moves _n positions forward in the list  of  matches;  a  negative
+              argument  may  be  used to move backward through the list.  This
+              command is intended to be  bound  to  TTAABB,  but  is  unbound  by
+              default.
+       mmeennuu--ccoommpplleettee--bbaacckkwwaarrdd
+              Identical  to mmeennuu--ccoommpplleettee, but moves backward through the list
+              of possible completions, as if mmeennuu--ccoommpplleettee had  been  given  a
+              negative argument.  This command is unbound by default.
+       ddeelleettee--cchhaarr--oorr--lliisstt
+              Deletes  the  character under the cursor if not at the beginning
+              or end of the line (like ddeelleettee--cchhaarr).  If at  the  end  of  the

+              as the mark.
+       cchhaarraacctteerr--sseeaarrcchh ((CC--]]))
+              A character is read and point is moved to the next occurrence of

+              rences.
+       cchhaarraacctteerr--sseeaarrcchh--bbaacckkwwaarrdd ((MM--CC--]]))
+              A  character  is  read and point is moved to the previous occur-

+       sskkiipp--ccssii--sseeqquueennccee
+              Read  enough  characters to consume a multi-key sequence such as
+              those defined for keys like Home and End.  Such sequences  begin
+              with a Control Sequence Indicator (CSI), usually ESC-[.  If this
+              sequence is bound to "\[", keys producing  such  sequences  will
+              have  no  effect  unless explicitly bound to a readline command,
+              instead of inserting stray characters into the  editing  buffer.
+              This is unbound by default, but usually bound to ESC-[.
+       iinnsseerrtt--ccoommmmeenntt ((MM--##))
+              Without  a  numeric  argument,  the  value  of the readline ccoomm--
+              mmeenntt--bbeeggiinn variable is inserted at the beginning of the  current
+              line.  If a numeric argument is supplied, this command acts as a
+              toggle:  if the characters at the beginning of the line  do  not
+              match  the value of ccoommmmeenntt--bbeeggiinn, the value is inserted, other-
+              wise the characters in ccoommmmeenntt--bbeeggiinn are deleted from the begin-
+              ning  of the line.  In either case, the line is accepted as if a
+              newline had been typed.   The  default  value  of  ccoommmmeenntt--bbeeggiinn
+              makes  the  current line a shell comment.  If a numeric argument
+              causes the comment character to be removed,  the  line  will  be
+              executed by the shell.

+DDEEFFAAUULLTT KKEEYY BBIINNDDIINNGGSS
+       The following is a list of the default emacs and vi bindings.   Charac-
+       ters  with  the  eighth  bit  set are written as M-<character>, and are
+       referred to as _m_e_t_a_f_i_e_d characters.  The printable ASCII characters not
+       mentioned  in  the  list  of  emacs  standard bindings are bound to the
+       sseellff--iinnsseerrtt function, which just inserts the given character  into  the
+       input line.  In vi insertion mode, all characters not specifically men-
+       tioned are bound to sseellff--iinnsseerrtt.  Characters assigned to signal genera-
+       tion by _s_t_t_y(1) or the terminal driver, such as C-Z or C-C, retain that
+       function.  Upper and lower case metafied characters are  bound  to  the
+       same  function in the emacs mode meta keymap.  The remaining characters
+       are unbound, which causes readline to ring the  bell  (subject  to  the
+       setting of the bbeellll--ssttyyllee variable).

+.if t Readline is Copyright \(co 1989\-2011 Free Software Foundation, Inc.
+.SH DESCRIPTION
+.LP
+.B readline
+will read a line from the terminal
+and return it, using
+.B prompt
+as a prompt.  If 
+.B prompt
+is \fBNULL\fP or the empty string, no prompt is issued.
+The line returned is allocated with
+.IR malloc (3);
+the caller must free it when finished.  The line returned
+has the final newline removed, so only the text of the line
+remains.
+.LP
+.B readline
+offers editing capabilities while the user is entering the
+line.
+By default, the line editing commands
+are similar to those of emacs.
+A vi\-style line editing interface is also available.
+.LP
+This manual page describes only the most basic use of \fBreadline\fP.
+Much more functionality is available; see
+\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP
+for additional information.
+.SH RETURN VALUE
+.LP
+.B readline
+returns the text of the line read.  A blank line
+returns the empty string.  If
+.B EOF
+is encountered while reading a line, and the line is empty,
+.B NULL
+is returned.  If an
+.B EOF
+is read with a non\-empty line, it is
+treated as a newline.
+.SH NOTATION
+.LP
+An Emacs-style notation is used to denote
+keystrokes.  Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
+means Control\-N.  Similarly, 
+.I meta
+keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X.  (On keyboards
+without a 
+.I meta
+key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
+then the
+.I x
+key.  This makes ESC the \fImeta prefix\fP.
+The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
+or press the Escape key
+then hold the Control key while pressing the
+.I x
+key.)
+.PP
+Readline commands may be given numeric
+.IR arguments ,
+which normally act as a repeat count.  Sometimes, however, it is the
+sign of the argument that is significant.  Passing a negative argument
+to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
+causes that command to act in a backward direction.  Commands whose
+behavior with arguments deviates from this are noted.
+.PP
+When a command is described as \fIkilling\fP text, the text
+deleted is saved for possible future retrieval
+(\fIyanking\fP).  The killed text is saved in a
+\fIkill ring\fP.  Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once. 
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+.SH INITIALIZATION FILE
+.LP
+Readline is customized by putting commands in an initialization
+file (the \fIinputrc\fP file).
+The name of this file is taken from the value of the
+.B INPUTRC
+environment variable.  If that variable is unset, the default is
+.IR ~/.inputrc .
+If that file  does not exist or cannot be read, the ultimate default is
+.IR /etc/inputrc .
+When a program which uses the readline library starts up, the
+init file is read, and the key bindings and variables are set.
+There are only a few basic constructs allowed in the
+readline init file.  Blank lines are ignored.
+Lines beginning with a \fB#\fP are comments.
+Lines beginning with a \fB$\fP indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+Each program using this library may add its own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+.sp
+into the 
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized while
+processing key bindings:
+.IR DEL ,
+.IR ESC ,
+.IR ESCAPE ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR RUBOUT ,
+.IR SPACE ,
+.IR SPC ,
+and
+.IR TAB .
+.PP
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a \fImacro\fP).
+.PP
+.SS Key Bindings
+.PP
+The syntax for controlling key bindings in the
+.I inputrc
+file is simple.  All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound. The name may be specified in one of two ways:
+as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
+prefixes, or as a key sequence.
+The name and key sequence are separated by a colon.  There can be no
+whitespace between the name and the colon.
+.PP
+When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
+.I keyname
+is the name of a key spelled out in English.  For example:
+.sp
+.RS
+Control\-u: universal\-argument
+.br
+Meta\-Rubout: backward\-kill\-word
+.br
+Control\-o: "> output"
+.RE
+.LP
+In the above example,
+.I C\-u
+is bound to the function
+.BR universal\-argument ,
+.I M-DEL
+is bound to the function
+.BR backward\-kill\-word ,
+and
+.I C\-o
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+.if t \f(CW> output\fP
+.if n ``> output''
+into the line).
+.PP
+In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.B keyseq
+differs from
+.B keyname
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes.  Some GNU Emacs style key escapes can be
+used, as in the following example, but the symbolic character names
+are not recognized.
+.sp
+.RS
+"\eC\-u": universal\-argument
+.br
+"\eC\-x\eC\-r": re\-read\-init\-file
+.br
+"\ee[11~": "Function Key 1"
+.RE
+.PP
+In this example,
+.I C-u
+is again bound to the function
+.BR universal\-argument .
+.I "C-x C-r"
+is bound to the function
+.BR re\-read\-init\-file ,
+and 
+.I "ESC [ 1 1 ~"
+is bound to insert the text
+.if t \f(CWFunction Key 1\fP.
+.if n ``Function Key 1''.
+.PP
+The full set of GNU Emacs style escape sequences available when specifying
+key sequences is
+.RS
+.PD 0
+.TP
+.B \eC\-
+control prefix
+.TP
+.B \eM\-
+meta prefix
+.TP
+.B \ee
+an escape character
+.TP
+.B \e\e
+backslash
+.TP
+.B \e"
+literal ", a double quote
+.TP
+.B \e'
+literal ', a single quote
+.RE
+.PD
+.PP
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+.RS
+.PD 0
+.TP
+.B \ea
+alert (bell)
+.TP
+.B \eb
+backspace
+.TP
+.B \ed
+delete
+.TP
+.B \ef
+form feed
+.TP
+.B \en
+newline
+.TP
+.B \er
+carriage return
+.TP
+.B \et
+horizontal tab
+.TP
+.B \ev
+vertical tab
+.TP
+.B \e\fInnn\fP
+the eight-bit character whose value is the octal value \fInnn\fP
+(one to three digits)
+.TP
+.B \ex\fIHH\fP
+the eight-bit character whose value is the hexadecimal value \fIHH\fP
+(one or two hex digits)
+.RE
+.PD
+.PP
+When entering the text of a macro, single or double quotes should
+be used to indicate a macro definition.  Unquoted text
+is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including " and '.
+.PP
+.B Bash
+allows the current readline key bindings to be displayed or modified
+with the
+.B bind
+builtin command.  The editing mode may be switched during interactive
+use by using the
+.B \-o
+option to the
+.B set
+builtin command.  Other programs using this library provide
+similar mechanisms.  The
+.I inputrc
+file may be edited and re-read if a program does not provide
+any other means to incorporate new bindings.
+.SS Variables
+.PP
+Readline has variables that can be used to further customize its
+behavior.  A variable may be set in the
+.I inputrc
+file with a statement of the form
+.RS
+.PP
+\fBset\fP \fIvariable\-name\fP \fIvalue\fP
+.RE
+.PP
+Except where noted, readline variables can take the values
+.B On
+or
+.B Off
+(without regard to case).
+Unrecognized variable names are ignored.
+When a variable value is read, empty or null values, "on" (case-insensitive),
+and "1" are equivalent to \fBOn\fP.  All other values are equivalent to
+\fBOff\fP.
+The variables and their default values are:
+.PP
+.PD 0
+.TP
+.B bell\-style (audible)
+Controls what happens when readline wants to ring the terminal bell.
+If set to \fBnone\fP, readline never rings the bell.  If set to
+\fBvisible\fP, readline uses a visible bell if one is available.
+If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
+.TP
+.B bind\-tty\-special\-chars (On)
+If set to \fBOn\fP, readline attempts to bind the control characters  
+treated specially by the kernel's terminal driver to their readline
+equivalents.
+.TP
+.B comment\-begin (``#'')
+The string that is inserted in \fBvi\fP mode when the
+.B insert\-comment
+command is executed.
+This command is bound to
+.B M\-#
+in emacs mode and to
+.B #
+in vi command mode.
+.TP
+.B completion\-display\-width (-1)
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+.TP 
+.B completion\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.TP
+.B completion\-map\-case (Off)
+If set to \fBOn\fP, and \fBcompletion\-ignore\-case\fP is enabled, readline
+treats hyphens (\fI\-\fP) and underscores (\fI_\fP) as equivalent when
+performing case\-insensitive filename matching and completion.
+.TP
+.B completion\-prefix\-display\-length (0)
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+.TP
+.B completion\-query\-items (100)
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the \fBpossible\-completions\fP command.
+It may be set to any integer value greater than or equal to
+zero.  If the number of possible completions is greater than
+or equal to the value of this variable, the user is asked whether
+or not he wishes to view them; otherwise they are simply listed
+on the terminal.  A negative value causes readline to never ask.
+.TP
+.B convert\-meta (On)
+If set to \fBOn\fP, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prefixing it with an
+escape character (in effect, using escape as the \fImeta prefix\fP).
+.TP
+.B disable\-completion (Off)
+If set to \fBOn\fP, readline will inhibit word completion.  Completion 
+characters will be inserted into the line as if they had been
+mapped to \fBself-insert\fP.
+.TP
+.B editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to \fIEmacs\fP or \fIvi\fP.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.TP
+.B echo\-control\-characters (On)
+When set to \fBOn\fP, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.
+.TP
+.B enable\-keypad (Off)
+When set to \fBOn\fP, readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.
+.TP
+.B enable\-meta\-key (On)
+When set to \fBOn\fP, readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+.TP
+.B expand\-tilde (Off)
+If set to \fBOn\fP, tilde expansion is performed when readline
+attempts word completion.
+.TP
+.B history\-preserve\-point (Off)
+If set to \fBOn\fP, the history code attempts to place point at the 
+same location on each history line retrieved with \fBprevious-history\fP 
+or \fBnext-history\fP.
+.TP
+.B history\-size (0)
+Set the maximum number of history entries saved in the history list.  If
+set to zero, the number of entries in the history list is not limited.
+.TP
+.B horizontal\-scroll\-mode (Off)
+When set to \fBOn\fP, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+.TP
+.B input\-meta (Off)
+If set to \fBOn\fP, readline will enable eight-bit input (that is,
+it will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The name
+.B meta\-flag
+is a synonym for this variable.
+.TP
+.B isearch\-terminators (``C\-[ C\-J'')
+The string of characters that should terminate an incremental
+search without subsequently executing the character as a command.
+If this variable has not been given a value, the characters
+\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
+.TP
+.B keymap (emacs)
+Set the current readline keymap.  The set of legal keymap names is
+\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+vi-command\fP, and
+.IR vi-insert .
+\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
+equivalent to \fIemacs-standard\fP.  The default value is
+.IR emacs .
+The value of
+.B editing\-mode
+also affects the default keymap.
+.TP
+.B mark\-directories (On)
+If set to \fBOn\fP, completed directory names have a slash
+appended.
+.TP
+.B mark\-modified\-lines (Off)
+If set to \fBOn\fP, history lines that have been modified are displayed
+with a preceding asterisk (\fB*\fP).
+.TP
+.B mark\-symlinked\-directories (Off)
+If set to \fBOn\fP, completed names which are symbolic links to directories
+have a slash appended (subject to the value of
+\fBmark\-directories\fP).
+.TP
+.B match\-hidden\-files (On)
+This variable, when set to \fBOn\fP, causes readline to match files whose 
+names begin with a `.' (hidden files) when performing filename     
+completion.
+If set to \fBOff\fP, the leading `.' must be
+supplied by the user in the filename to be completed.
+.TP
+.B menu\-complete\-display\-prefix (Off)
+If set to \fBOn\fP, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.
+.TP
+.B output\-meta (Off)
+If set to \fBOn\fP, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+.TP
+.B page\-completions (On)
+If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager
+to display a screenful of possible completions at a time.
+.TP
+.B print\-completions\-horizontally (Off)
+If set to \fBOn\fP, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+.TP
+.B revert\-all\-at\-newline (Off)
+If set to \fBOn\fP, readline will undo all changes to history lines
+before returning when \fBaccept\-line\fP is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to \fBreadline\fP.
+.TP
+.B show\-all\-if\-ambiguous (Off)
+This alters the default behavior of the completion functions.  If
+set to
+.BR On ,
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+.TP
+.B show\-all\-if\-unmodified (Off)
+This alters the default behavior of the completion functions in
+a fashion similar to \fBshow\-all\-if\-ambiguous\fP.
+If set to
+.BR On , 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share 
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+.TP
+.B skip\-completed\-text (Off)
+If set to \fBOn\fP, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+.TP
+.B visible\-stats (Off)
+If set to \fBOn\fP, a character denoting a file's type as reported  
+by \fIstat\fP(2) is appended to the filename when listing possible
+completions.
+.PD
+.SS Conditional Constructs
+.PP
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+.IP \fB$if\fP
+The 
+.B $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$if\fP directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the \fBset keymap\fP command, for instance, to set bindings in
+the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
+readline is starting out in emacs mode.
+.IP \fBterm\fP
+The \fBterm=\fP form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+.B =
+is tested against the full name of the terminal and the portion
+of the terminal name before the first \fB\-\fP.  This allows
+.I sun
+to match both
+.I sun
+and
+.IR sun\-cmd ,
+for instance.
+.IP \fBapplication\fP
+The \fBapplication\fP construct is used to include
+application-specific settings.  Each program using the readline
+library sets the \fIapplication name\fP, and an initialization
+file can test for a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in \fBbash\fP:
+.sp 1
+.RS
+.nf
+\fB$if\fP Bash
+# Quote the current or previous word
+"\eC-xq": "\eeb\e"\eef\e""
+\fB$endif\fP
+.fi
+.RE
+.RE
+.IP \fB$endif\fP
+This command, as seen in the previous example, terminates an
+\fB$if\fP command.
+.IP \fB$else\fP
+Commands in this branch of the \fB$if\fP directive are executed if
+the test fails.
+.IP \fB$include\fP
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.  For example, the following directive
+would read \fI/etc/inputrc\fP:
+.sp 1
+.RS
+.nf
+\fB$include\fP \^ \fI/etc/inputrc\fP
+.fi 
+.RE
+.SH SEARCHING
+.PP
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:
+.I incremental
+and
+.IR non-incremental .
+.PP
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+\fBC\-r\fP.  Typing \fBC\-s\fP searches forward through the history.
+The characters present in the value of the \fBisearch-terminators\fP
+variable are used to terminate an incremental search.
+If that variable has not been assigned a value the \fIEscape\fP and
+\fBC\-J\fP characters will terminate an incremental search.
+\fBC\-G\fP will abort an incremental search and restore the original
+line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+.PP
+To find other matching entries in the history list, type \fBC\-s\fP or
+\fBC\-r\fP as appropriate.
+This will search backward or forward in the history for the next
+line matching the search string typed so far.
+Any other key sequence bound to a readline command will terminate
+the search and execute that command.
+For instance, a newline will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+.PP
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+.SH EDITING COMMANDS
+.PP
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.
+.PP
+In the following descriptions, \fIpoint\fP refers to the current cursor
+position, and \fImark\fP refers to a cursor position saved by the
+\fBset\-mark\fP command.
+The text between the point and mark is referred to as the \fIregion\fP.
+.SS Commands for Moving
+.PP
+.PD 0

+Refresh the current line.
+.PD
+.SS Commands for Manipulating the History
+.PP
+.PD 0
+.TP
+.B accept\-line (Newline, Return)
+Accept the line regardless of where the cursor is.
+If this line is
+non-empty, it may be added to the history list for future recall with
+\fBadd_history()\fP.
+If the line is a modified history line, the history line is restored to its original state.
+.TP
+.B previous\-history (C\-p)
+Fetch the previous command from the history list, moving back in
+the list.
+.TP
+.B next\-history (C\-n)
+Fetch the next command from the history list, moving forward in the
+list.
+.TP
+.B beginning\-of\-history (M\-<)
+Move to the first line in the history.
+.TP
+.B end\-of\-history (M\->)
+Move to the end of the input history, i.e., the line currently being
+entered.
+.TP
+.B reverse\-search\-history (C\-r)
+Search backward starting at the current line and moving `up' through
+the history as necessary.  This is an incremental search.
+.TP
+.B forward\-search\-history (C\-s)
+Search forward starting at the current line and moving `down' through
+the history as necessary.  This is an incremental search.
+.TP
+.B non\-incremental\-reverse\-search\-history (M\-p)
+Search backward through the history starting at the current line
+using a non-incremental search for a string supplied by the user.
+.TP
+.B non\-incremental\-forward\-search\-history (M\-n)
+Search forward through the history using a non-incremental search
+for a string supplied by the user.
+.TP
+.B history\-search\-forward
+Search forward through the history for the string of characters
+between the start of the current line and the current cursor
+position (the \fIpoint\fP).
+This is a non-incremental search.
+.TP
+.B history\-search\-backward
+Search backward through the history for the string of characters
+between the start of the current line and the point.
+This is a non-incremental search.
+.TP
+.B yank\-nth\-arg (M\-C\-y)
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument
+.IR n ,
+insert the \fIn\fPth word from the previous command (the words
+in the previous command begin with word 0).  A negative argument
+inserts the \fIn\fPth word from the end of the previous command.
+Once the argument \fIn\fP is computed, the argument is extracted
+as if the "!\fIn\fP" history expansion had been specified.
+.TP
+.B
+yank\-last\-arg (M\-.\^, M\-_\^)
+Insert the last argument to the previous command (the last word of
+the previous history entry).
+With a numeric argument, behave exactly like \fByank\-nth\-arg\fP.
+Successive calls to \fByank\-last\-arg\fP move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history.  A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,
+as if the "!$" history expansion had been specified.
+.PD
+.SS Commands for Changing Text
+.PP
+.PD 0
+.TP
+.B delete\-char (C\-d)
+Delete the character at point.  If point is at the
+beginning of the line, there are no characters in the line, and
+the last character typed was not bound to \fBdelete\-char\fP, then return
+.SM
+.BR EOF .
+.TP
+.B backward\-delete\-char (Rubout)
+Delete the character behind the cursor.  When given a numeric argument,
+save the deleted text on the kill ring.
+.TP
+.B forward\-backward\-delete\-char   
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.
+.TP
+.B quoted\-insert (C\-q, C\-v)
+Add the next character that you type to the line verbatim.  This is
+how to insert characters like \fBC\-q\fP, for example.
+.TP
+.B tab\-insert (M-TAB)
+Insert a tab character.
+.TP
+.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...)
+Insert the character typed.
+.TP
+.B transpose\-chars (C\-t)
+Drag the character before point forward over the character at point,
+moving point forward as well.
+If point is at the end of the line, then this transposes
+the two characters before point.
+Negative arguments have no effect.
+.TP
+.B transpose\-words (M\-t)
+Drag the word before point past the word after point,
+moving point over that word as well.
+If point is at the end of the line, this transposes
+the last two words on the line.
+.TP
+.B upcase\-word (M\-u)
+Uppercase the current (or following) word.  With a negative argument,
+uppercase the previous word, but do not move point.
+.TP
+.B downcase\-word (M\-l)
+Lowercase the current (or following) word.  With a negative argument,
+lowercase the previous word, but do not move point.
+.TP
+.B capitalize\-word (M\-c)
+Capitalize the current (or following) word.  With a negative argument,
+capitalize the previous word, but do not move point.
+.TP
+.B overwrite\-mode
+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+\fBemacs\fP mode; \fBvi\fP mode does overwrite differently.
+Each call to \fIreadline()\fP starts in insert mode.
+In overwrite mode, characters bound to \fBself\-insert\fP replace   
+the text at point rather than pushing the text to the right.
+Characters bound to \fBbackward\-delete\-char\fP replace the character
+before point with a space.  By default, this command is unbound.
+.PD
+.SS Killing and Yanking
+.PP
+.PD 0
+.TP
+.B kill\-line (C\-k)
+Kill the text from point to the end of the line.
+.TP
+.B backward\-kill\-line (C\-x Rubout)
+Kill backward to the beginning of the line.
+.TP
+.B unix\-line\-discard (C\-u)
+Kill backward from point to the beginning of the line.
+The killed text is saved on the kill-ring.
+.\" There is no real difference between this and backward-kill-line
+.TP
+.B kill\-whole\-line
+Kill all characters on the current line, no matter where point is.
+.TP
+.B kill\-word  (M\-d)
+Kill from point the end of the current word, or if between
+words, to the end of the next word.  Word boundaries are the same as
+those used by \fBforward\-word\fP.
+.TP
+.B backward\-kill\-word (M\-Rubout)
+Kill the word behind point.
+Word boundaries are the same as those used by \fBbackward\-word\fP.
+.TP
+.B unix\-word\-rubout (C\-w)
+Kill the word behind point, using white space as a word boundary.
+The killed text is saved on the kill-ring.
+.TP
+.B unix\-filename\-rubout
+Kill the word behind point, using white space and the slash character
+as the word boundaries.
+The killed text is saved on the kill-ring.
+.TP
+.B delete\-horizontal\-space (M\-\e)
+Delete all spaces and tabs around point.
+.TP
+.B kill\-region
+Kill the text between the point and \fImark\fP (saved cursor position).
+This text is referred to as the \fIregion\fP.
+.TP
+.B copy\-region\-as\-kill
+Copy the text in the region to the kill buffer.
+.TP
+.B copy\-backward\-word
+Copy the word before point to the kill buffer.
+The word boundaries are the same as \fBbackward\-word\fP.
+.TP
+.B copy\-forward\-word
+Copy the word following point to the kill buffer.
+The word boundaries are the same as \fBforward\-word\fP.
+.TP
+.B yank (C\-y)
+Yank the top of the kill ring into the buffer at point.
+.TP
+.B yank\-pop (M\-y)
+Rotate the kill ring, and yank the new top.  Only works following
+.B yank
+or
+.BR yank\-pop .
+.PD
+.SS Numeric Arguments
+.PP
+.PD 0
+.TP
+.B digit\-argument (M\-0, M\-1, ..., M\-\-)
+Add this digit to the argument already accumulating, or start a new
+argument.  M\-\- starts a negative argument.
+.TP
+.B universal\-argument
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing
+.B universal\-argument
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+.PD
+.SS Completing
+.PP
+.PD 0
+.TP
+.B complete (TAB)
+Attempt to perform completion on the text before point.
+The actual completion performed is application-specific.
+.BR Bash ,
+for instance, attempts completion treating the text as a variable
+(if the text begins with \fB$\fP), username (if the text begins with
+\fB~\fP), hostname (if the text begins with \fB@\fP), or
+command (including aliases and functions) in turn.  If none
+of these produces a match, filename completion is attempted.
+.BR Gdb ,
+on the other hand,
+allows completion of program functions and variables, and
+only attempts filename completion under certain circumstances.
+.TP
+.B possible\-completions (M\-?)
+List the possible completions of the text before point.
+When displaying completions, readline sets the number of columns used
+for display to the value of \fBcompletion-display-width\fP, the value of
+the environment variable
+.SM
+.BR COLUMNS ,
+or the screen width, in that order.
+.TP
+.B insert\-completions (M\-*)
+Insert all completions of the text before point
+that would have been generated by
+\fBpossible\-completions\fP.
+.TP
+.B menu\-complete
+Similar to \fBcomplete\fP, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of \fBmenu\-complete\fP steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung
+(subject to the setting of \fBbell\-style\fP)
+and the original text is restored.
+An argument of \fIn\fP moves \fIn\fP positions forward in the list
+of matches; a negative argument may be used to move backward 
+through the list.
+This command is intended to be bound to \fBTAB\fP, but is unbound
+by default.
+.TP
+.B menu\-complete\-backward
+Identical to \fBmenu\-complete\fP, but moves backward through the list
+of possible completions, as if \fBmenu\-complete\fP had been given a
+negative argument.  This command is unbound by default.
+.TP
+.B delete\-char\-or\-list
+Deletes the character under the cursor if not at the beginning or
+end of the line (like \fBdelete-char\fP).
+If at the end of the line, behaves identically to
+\fBpossible-completions\fP.
+.PD
+.SS Keyboard Macros
+.PP
+.PD 0
+.TP
+.B start\-kbd\-macro (C\-x (\^)
+Begin saving the characters typed into the current keyboard macro.
+.TP
+.B end\-kbd\-macro (C\-x )\^)
+Stop saving the characters typed into the current keyboard macro
+and store the definition.
+.TP
+.B call\-last\-kbd\-macro (C\-x e)
+Re-execute the last keyboard macro defined, by making the characters
+in the macro appear as if typed at the keyboard.
+.PD
+.SS Miscellaneous
+.PP
+.PD 0
+.TP
+.B re\-read\-init\-file (C\-x C\-r)
+Read in the contents of the \fIinputrc\fP file, and incorporate
+any bindings or variable assignments found there.
+.TP
+.B abort (C\-g)
+Abort the current editing command and
+ring the terminal's bell (subject to the setting of
+.BR bell\-style ).
+.TP
+.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...)
+If the metafied character \fIx\fP is lowercase, run the command
+that is bound to the corresponding uppercase character.
+.TP
+.B prefix\-meta (ESC)
+Metafy the next character typed.
+.SM
+.B ESC
+.B f
+is equivalent to
+.BR Meta\-f .
+.TP
+.B undo (C\-_, C\-x C\-u)
+Incremental undo, separately remembered for each line.
+.TP
+.B revert\-line (M\-r)
+Undo all changes made to this line.  This is like executing the
+.B undo
+command enough times to return the line to its initial state.
+.TP
+.B tilde\-expand (M\-&)
+Perform tilde expansion on the current word.
+.TP
+.B set\-mark (C\-@, M\-<space>)
+Set the mark to the point.  If a
+numeric argument is supplied, the mark is set to that position.
+.TP
+.B exchange\-point\-and\-mark (C\-x C\-x)
+Swap the point with the mark.  The current cursor position is set to
+the saved position, and the old cursor position is saved as the mark.
+.TP
+.B character\-search (C\-])
+A character is read and point is moved to the next occurrence of that
+character.  A negative count searches for previous occurrences.
+.TP
+.B character\-search\-backward (M\-C\-])
+A character is read and point is moved to the previous occurrence of that
+character.  A negative count searches for subsequent occurrences.
+.TP
+.B skip\-csi\-sequence
+Read enough characters to consume a multi-key sequence such as those
+defined for keys like Home and End.  Such sequences begin with a
+Control Sequence Indicator (CSI), usually ESC\-[.  If this sequence is
+bound to "\e[", keys producing such sequences will have no effect
+unless explicitly bound to a readline command, instead of inserting
+stray characters into the editing buffer.  This is unbound by default,
+but usually bound to ESC\-[.
+.TP
+.B insert\-comment (M\-#)
+Without a numeric argument, the value of the readline
+.B comment\-begin
+variable is inserted at the beginning of the current line.
+If a numeric argument is supplied, this command acts as a toggle:  if
+the characters at the beginning of the line do not match the value   
+of \fBcomment\-begin\fP, the value is inserted, otherwise             
+the characters in \fBcomment-begin\fP are deleted from the beginning of
+the line.
+In either case, the line is accepted as if a newline had been typed.
+The default value of
+.B comment\-begin
+makes the current line a shell comment.
+If a numeric argument causes the comment character to be removed, the line
+will be executed by the shell.
+.TP
+.B dump\-functions
+Print all of the functions and their key bindings to the
+readline output stream.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-variables
+Print all of the settable variables and their values to the
+readline output stream.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B dump\-macros
+Print all of the readline key sequences bound to macros and the
+strings they output.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an \fIinputrc\fP file.
+.TP
+.B emacs\-editing\-mode (C\-e)
+When in
+.B vi
+command mode, this causes a switch to
+.B emacs
+editing mode.
+.TP
+.B vi\-editing\-mode (M\-C\-j)
+When in
+.B emacs

+.SH DEFAULT KEY BINDINGS
+.LP
+The following is a list of the default emacs and vi bindings.
+Characters with the eighth bit set are written as M\-<character>, and
+are referred to as
+.I metafied
+characters.
+The printable ASCII characters not mentioned in the list of emacs
+standard bindings are bound to the
+.B self\-insert
+function, which just inserts the given character into the input line.
+In vi insertion mode, all characters not specifically mentioned are
+bound to
+.BR self\-insert .
+Characters assigned to signal generation by
+.IR stty (1)
+or the terminal driver, such as C-Z or C-C,
+retain that function.
+Upper and lower case metafied characters are bound to the same function in
+the emacs mode meta keymap.
+The remaining characters are unbound, which causes readline
+to ring the bell (subject to the setting of the
+.B bell\-style
+variable).

+
+The following paragraphs describe the notation used to represent
+keystrokes.
+</P><P>
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+</P><P>
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
+</P><P>
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
+</P><P>
+
+In addition, several keys have their own names.  Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="readline.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<!--docid::SEC3::-->
+<P>
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+</P><P>
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with <KBD>C-f</KBD>.
+</P><P>
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the bare

+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
+<KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly

+<EM>Killing</EM> text means to delete the text from the line, but to save

+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)

+Any number of consecutive kills save all of the killed text together, so

+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing

+<H3> 1.2.4 Readline Arguments </H3>
+<!--docid::SEC7::-->
+<P>
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+<!--docid::SEC9::-->
+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.  If that
+file does not exist or cannot be read, the ultimate default is
+<TT>`/etc/inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+<DT><CODE>completion-display-width</CODE>
+<DD><A NAME="IDX8"></A>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal

+replaced with an ellipsis when displaying possible completions.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX12"></A>
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.

+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
+<P>

+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>echo-control-characters</CODE>

+<P>
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX29"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the

+<P>
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX30"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager

+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the <SAMP>`e'</SAMP> in <SAMP>`Makefile'</SAMP> will result in <SAMP>`Makefile'</SAMP>
+rather than <SAMP>`Makefilefile'</SAMP>, assuming there is a single possible

+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is

+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+</P><P>

+<P>
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+With an argument <VAR>n</VAR>,
+insert the <VAR>n</VAR>th word from the previous command (the words
+in the previous command begin with word 0).  A negative argument
+inserts the <VAR>n</VAR>th word from the end of the previous command.

+With a numeric argument, behave exactly like <CODE>yank-nth-arg</CODE>.
+Successive calls to <CODE>yank-last-arg</CODE> move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines
+the direction to move through the history.  A negative argument switches
+the direction through the history (back or forward).
+The history expansion facilities are used to extract the last argument,

+Negative arguments have no effect.
+<P>
+
+<A NAME="IDX92"></A>
+<DT><CODE>transpose-words (M-t)</CODE>
+<DD><A NAME="IDX93"></A>
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+<P>
+
+<A NAME="IDX94"></A>
+<DT><CODE>upcase-word (M-u)</CODE>
+<DD><A NAME="IDX95"></A>

+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+<CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
+Each call to <CODE>readline()</CODE> starts in insert mode.
+<P>
+
+In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
+the text at point rather than pushing the text to the right.
+Characters bound to <CODE>backward-delete-char</CODE> replace the character
+before point with a space.

+<H2> 2.1 Basic Behavior </H2>
+<!--docid::SEC24::-->
+<P>
+
+Many programs provide a command line interface, such as <CODE>mail</CODE>,
+<CODE>ftp</CODE>, and <CODE>sh</CODE>.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+<CODE>gets()</CODE> or <CODE>fgets()</CODE>.
+</P><P>
+
+<A NAME="IDX190"></A>
+<A NAME="IDX191"></A>
+</P><P>
+
+The function <CODE>readline()</CODE> prints a prompt <VAR>prompt</VAR>
+and then reads and returns a single line of text from the user.
+If <VAR>prompt</VAR> is <CODE>NULL</CODE> or the empty string, no prompt is displayed.
+The line <CODE>readline</CODE> returns is allocated with <CODE>malloc()</CODE>;
+the caller should <CODE>free()</CODE> the line when it has finished with it.
+The declaration for <CODE>readline</CODE> in ANSI C is
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *readline (const char *<VAR>prompt</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+So, one might say
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>char *line = readline ("Enter a line: ");</CODE>
+</pre></td></tr></table>in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+</P><P>
+
+If <CODE>readline</CODE> encounters an <CODE>EOF</CODE> while reading the line, and the
+line is empty at that point, then <CODE>(char *)NULL</CODE> is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+</P><P>
+
+If you want the user to be able to get at the line later, (with
+<KBD>C-p</KBD> for example), you must call <CODE>add_history()</CODE> to save the
+line away in a <EM>history</EM> list of such lines.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>add_history (line)</CODE>;
+</pre></td></tr></table></P><P>
+
+For full details on the GNU History Library, see the associated manual.
+</P><P>
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard <CODE>gets()</CODE> library
+function, and has the advantage of no static buffer to overflow:
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    {
+      free (line_read);
+      line_read = (char *)NULL;
+    }
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read &#38;&#38; *line_read)
+    add_history (line_read);
+
+  return (line_read);
+}
+</pre></td></tr></table></P><P>
+
+This function gives the user the default behaviour of <KBD>TAB</KBD>
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the <KBD>TAB</KBD> key
+with <CODE>rl_bind_key()</CODE>.
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int rl_bind_key (int <VAR>key</VAR>, rl_command_func_t *<VAR>function</VAR>);</CODE>
+</pre></td></tr></table></P><P>
+
+<CODE>rl_bind_key()</CODE> takes two arguments: <VAR>key</VAR> is the character that
+you want to bind, and <VAR>function</VAR> is the address of the function to
+call when <VAR>key</VAR> is pressed.  Binding <KBD>TAB</KBD> to <CODE>rl_insert()</CODE>
+makes <KBD>TAB</KBD> insert itself.
+<CODE>rl_bind_key()</CODE> returns non-zero if <VAR>key</VAR> is not a valid
+ASCII character code (between 0 and 255).
+</P><P>
+
+Thus, to disable the default <KBD>TAB</KBD> behavior, the following suffices:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>rl_bind_key ('\t', rl_insert);</CODE>
+</pre></td></tr></table></P><P>
+
+This code should be executed once at the start of your program; you
+might write a function called <CODE>initialize_readline()</CODE> which
+performs this and other desired initializations, such as installing
+custom completers (see section <A HREF="readline.html#SEC44">2.6 Custom Completers</A>).

+<!--docid::SEC25::-->
+<P>
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+</P><P>
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file <CODE>&#60;readline/readline.h&#62;</CODE>
+in any file that uses Readline's features.  Since some of the definitions
+in <CODE>readline.h</CODE> use the <CODE>stdio</CODE> library, the file
+<CODE>&#60;stdio.h&#62;</CODE> should be included before <CODE>readline.h</CODE>.
+</P><P>
+
+<CODE>readline.h</CODE> defines a C preprocessor variable that should
+be treated as an integer, <CODE>RL_READLINE_VERSION</CODE>, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x<VAR>MMmm</VAR>.  <VAR>MM</VAR> is the two-digit major
+version number; <VAR>mm</VAR> is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+<CODE>RL_READLINE_VERSION</CODE> would be <CODE>0x0402</CODE>.

+<H3> 2.2.2 Writing a New Function </H3>
+<!--docid::SEC27::-->
+<P>
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+</P><P>
+
+The calling sequence for a command <CODE>foo</CODE> looks like
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre><CODE>int foo (int count, int key)</CODE>
+</pre></td></tr></table></P><P>
+
+where <VAR>count</VAR> is the numeric argument (or 1 if defaulted) and
+<VAR>key</VAR> is the key that invoked this function.
+</P><P>
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+</P><P>
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.

+<!--docid::SEC30::-->
+<P>
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>Meta-Rubout:	backward-kill-word
+</pre></td></tr></table></P><P>
+
+This binds the keystroke <KBD>Meta-Rubout</KBD> to the function
+<EM>descriptively</EM> named <CODE>backward-kill-word</CODE>.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:

+<DL>
+<DT><U>Function:</U> int <B>rl_add_defun</B> <I>(const char *name, rl_command_func_t *function, int key)</I>

+the function that gets called.  If <VAR>key</VAR> is not -1, then bind it to
+<VAR>function</VAR> using <CODE>rl_bind_key()</CODE>.
+</DL>
+</P><P>
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.

+If your function simply inserts text once, or deletes text once, and

+</P><P>
+
+If you do multiple insertions or multiple deletions, or any combination

+This is done with <CODE>rl_begin_undo_group()</CODE> and
+<CODE>rl_end_undo_group()</CODE>.

+<H2> 2.5 Readline Signal Handling </H2>
+<!--docid::SEC43::-->
+<P>
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+</P><P>
+
+Readline contains an internal signal handler that is installed for a
+number of signals (<CODE>SIGINT</CODE>, <CODE>SIGQUIT</CODE>, <CODE>SIGTERM</CODE>,
+<CODE>SIGALRM</CODE>, <CODE>SIGTSTP</CODE>, <CODE>SIGTTIN</CODE>, and <CODE>SIGTTOU</CODE>).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+<CODE>readline()</CODE> was called, reset the signal handling to what it was
+before <CODE>readline()</CODE> was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a <CODE>SIGINT</CODE> is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of <CODE>rl_free_line_state()</CODE> below).
+</P><P>
+
+There is an additional Readline signal handler, for <CODE>SIGWINCH</CODE>, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an <CODE>xterm</CODE>).  The Readline <CODE>SIGWINCH</CODE>
+handler updates Readline's internal screen size information, and then calls
+any <CODE>SIGWINCH</CODE> signal handler the calling application has installed. 
+Readline calls the application's <CODE>SIGWINCH</CODE> signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a <CODE>longjmp</CODE> back to a main processing loop), it <EM>must</EM>
+call <CODE>rl_cleanup_after_signal()</CODE> (described below), to restore the
+terminal state. 
+</P><P>
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling <CODE>readline()</CODE>, not in
+a signal handler, so Readline's internal signal state is not corrupted.

+<H3> 2.6.1 How Completing Works </H3>
+<!--docid::SEC45::-->
+<P>
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+</P><P>
+
+There are three major functions used to perform completion:
+</P><P>
+
+<OL>
+<LI>
+The user-interface function <CODE>rl_complete()</CODE>.  This function is
+called with the same arguments as other bindable Readline functions:
+<VAR>count</VAR> and <VAR>invoking_key</VAR>.
+It isolates the word to be completed and calls
+<CODE>rl_completion_matches()</CODE> to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+<P>
+
+<LI>
+The internal function <CODE>rl_completion_matches()</CODE> uses an
+application-supplied <EM>generator</EM> function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+<CODE>rl_completion_entry_function</CODE>.
+<P>
+
+<LI>
+The generator function is called repeatedly from
+<CODE>rl_completion_matches()</CODE>, returning a string each time.  The
+arguments to the generator function are <VAR>text</VAR> and <VAR>state</VAR>.
+<VAR>text</VAR> is the partial word to be completed.  <VAR>state</VAR> is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+<CODE>(char *)NULL</CODE> to inform <CODE>rl_completion_matches()</CODE> that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when <VAR>state</VAR> is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with <CODE>malloc()</CODE>; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+<EM>application-specific completion function</EM>.

+them to the partial word to be completed.  The function should
+perform any necesary application or system-specific conversion on

+PREAMBLE
+<P>
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document <EM>free</EM> in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+</P><P>
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+</P><P>
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+</P><P>
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+<P>
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The "Document", below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as "you".  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+</P><P>
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+</P><P>
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+</P><P>
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+</P><P>
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+</P><P>
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not "Transparent" is called "Opaque".
+</P><P>
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
+<FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification.  Examples
+of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
+<FONT SIZE="-1">JPG</FONT>.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
+<FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
+not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
+output purposes only.
+</P><P>
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+</P><P>
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+</P><P>
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+</P><P>
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+</P><P>
+
+<LI>
+VERBATIM COPYING
+<P>
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+</P><P>
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+</P><P>
+
+<LI>
+COPYING IN QUANTITY
+<P>
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+</P><P>
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+</P><P>
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+</P><P>
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+</P><P>
+
+<LI>
+MODIFICATIONS
+<P>
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+</P><P>
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+<P>
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+<P>
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+<P>
+
+<LI>
+Preserve all the copyright notices of the Document.
+<P>
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+<P>
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+<P>
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+<P>
+
+<LI>
+Include an unaltered copy of this License.
+<P>
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+<P>
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+<P>
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+<P>
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+<P>
+
+<LI>
+Delete any section Entitled "Endorsements".  Such a section
+may not be included in the Modified Version.
+<P>
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+<P>
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+<P>
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+</P><P>
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+</P><P>
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+</P><P>
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+</P><P>
+
+<LI>
+COMBINING DOCUMENTS
+<P>
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+</P><P>
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+</P><P>
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications".  You must delete all
+sections Entitled "Endorsements."
+</P><P>
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+<P>
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+</P><P>
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+</P><P>
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+<P>
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+</P><P>
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+</P><P>
+
+<LI>
+TRANSLATION
+<P>
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+</P><P>
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+</P><P>
+
+<LI>
+TERMINATION
+<P>
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+</P><P>
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+</P><P>
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+</P><P>
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+</P><P>
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+<P>
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+</P><P>
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+</P><P>
+
+<LI>
+RELICENSING
+<P>
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+</P><P>
+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+</P><P>
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+</P><P>
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.

+
+The operator of an MMC Site may republish an MMC contained in the site

+<!--docid::SEC50::-->
+<P>
+
+To use this License in a document you have written, include a copy of

+
+1.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text `C-k' is read as `Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text `M-k' is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text `M-C-k' is read as `Meta-Control-k' and describes the
+character produced by "metafying" `C-k'.
+
+   In addition, several keys have their own names.  Specifically,
+<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
+when seen in this text, or in an init file (*note Readline Init File::).
+If your keyboard lacks a <LFD> key, typing <C-j> will produce the
+desired character.  The <RET> key may be labeled <Return> or <Enter> on
+some keyboards.

+
+1.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.
+

+* Readline Bare Essentials::	The least you need to know about Readline.
+* Readline Movement Commands::	Moving about the input line.
+* Readline Killing Commands::	How to delete text, and how to get it back!

+
+1.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error
+until you have typed several other characters.  In that case, you can
+type `C-b' to move the cursor to the left, and then correct your
+mistake.  Afterwards, you can move the cursor to the right with `C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are `pushed over' to make room
+for the text that you have inserted.  Likewise, when you delete text
+behind the cursor, characters to the right of the cursor are `pulled
+back' to fill in the blank space created by the removal of the text.  A
+list of the bare essentials for editing the text of an input line
+follows.
+
+`C-b'
+     Move back one character.
+
+`C-f'
+     Move forward one character.
+
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+
+`C-d'
+     Delete the character underneath the cursor.
+
+Printing characters
+     Insert the character into the line at the cursor.
+
+`C-_' or `C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like `C-d', rather than the
+character to the left of the cursor.)

+
+1.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to `C-b', `C-f', `C-d', and
+<DEL>.  Here are some commands for moving more rapidly about the line.
+
+`C-a'
+     Move to the start of the line.
+
+`C-e'
+     Move to the end of the line.
+
+`M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+
+`M-b'
+     Move backward a word.
+
+`C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how `C-f' moves forward a character, while `M-f' moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.

+1.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into
+the line.  (`Cut' and `paste' are more recent jargon for `kill' and
+`yank'.)
+
+   If the description for a command says that it `kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.  
+
+   Here is the list of commands for killing text.
+
+`C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+`M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by `M-f'.
+
+`M-<DEL>'
+     Kill from the cursor the start of the current word, or, if between
+     words, to the start of the previous word.  Word boundaries are the
+     same as those used by `M-b'.
+
+`C-w'
+     Kill from the cursor to the previous whitespace.  This is
+     different than `M-<DEL>' because the word boundaries differ.
+
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+`C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+`M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `C-y' or `M-y'.

+
+1.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type `M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first `digit' typed is a minus
+sign (`-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give
+the `C-d' command an argument of 10, you could type `M-1 0 C-d', which
+will delete the next ten characters on the input line.

+
+File: readline.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+1.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.  There are two search modes:
+"incremental" and "non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters
+as needed to find the desired history entry.  To search backward in the
+history for a particular string, type `C-r'.  Typing `C-s' searches
+forward through the history.  The characters present in the value of
+the `isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+`C-J' characters will terminate an incremental search.  `C-g' will
+abort an incremental search and restore the original line.  When the
+search is terminated, the history entry containing the search string
+becomes the current line.
+
+   To find other matching entries in the history list, type `C-r' or
+`C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate the
+search and execute that command.  For instance, a <RET> will terminate
+the search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two
+`C-r's are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+1.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory.  The name of this file is taken from the value of the
+environment variable `INPUTRC'.  If that variable is unset, the default
+is `~/.inputrc'.  If that file does not exist or cannot be read, the
+ultimate default is `/etc/inputrc'.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the `C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+1.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init
+file.  Blank lines are ignored.  Lines beginning with a `#' are
+comments.  Lines beginning with a `$' indicate conditional constructs
+(*note Conditional Init Constructs::).  Other lines denote variable
+settings and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the `set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like
+     key binding to use `vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.  Unrecognized variable names are ignored.
+
+     Boolean variables (those that can be set to on or off) are set to
+     on if the value is null or empty, ON (case-insensitive), or 1.
+     Any other value results in the variable being set to off.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+    `bell-style'
+          Controls what happens when Readline wants to ring the
+          terminal bell.  If set to `none', Readline never rings the
+          bell.  If set to `visible', Readline uses a visible bell if
+          one is available.  If set to `audible' (the default),
+          Readline attempts to ring the terminal's bell.
+
+    `bind-tty-special-chars'
+          If set to `on', Readline attempts to bind the control
+          characters treated specially by the kernel's terminal driver
+          to their Readline equivalents.
+
+    `comment-begin'
+          The string to insert at the beginning of the line when the
+          `insert-comment' command is executed.  The default value is
+          `"#"'.
+
+    `completion-display-width'
+          The number of screen columns used to display possible matches
+          when performing completion.  The value is ignored if it is
+          less than 0 or greater than the terminal screen width.  A
+          value of 0 will cause matches to be displayed one per line.
+          The default value is -1.
+
+    `completion-ignore-case'
+          If set to `on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is `off'.
+
+    `completion-map-case'
+          If set to `on', and COMPLETION-IGNORE-CASE is enabled,
+          Readline treats hyphens (`-') and underscores (`_') as
+          equivalent when performing case-insensitive filename matching
+          and completion.
+
+    `completion-prefix-display-length'
+          The length in characters of the common prefix of a list of
+          possible completions that is displayed without modification.
+          When set to a value greater than zero, common prefixes longer
+          than this value are replaced with an ellipsis when displaying
+          possible completions.
+
+    `completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether the list of possibilities should be
+          displayed.  If the number of possible completions is greater
+          than this value, Readline will ask the user whether or not he
+          wishes to view them; otherwise, they are simply listed.  This
+          variable must be set to an integer value greater than or
+          equal to 0.  A negative value means Readline should never ask.
+          The default limit is `100'.
+
+    `convert-meta'
+          If set to `on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is `on'.
+
+    `disable-completion'
+          If set to `On', Readline will inhibit word completion.
+          Completion  characters will be inserted into the line as if
+          they had been mapped to `self-insert'.  The default is `off'.
+
+    `editing-mode'
+          The `editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either `emacs' or `vi'.
+
+    `echo-control-characters'
+          When set to `on', on operating systems that indicate they
+          support it, readline echoes a character corresponding to a
+          signal generated from the keyboard.  The default is `on'.
+
+    `enable-keypad'
+          When set to `on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is `off'.
+
+    `enable-meta-key'
+          When set to `on', Readline will try to enable any meta
+          modifier key the terminal claims to support when it is
+          called.  On many terminals, the meta key is used to send
+          eight-bit characters.  The default is `on'.
+
+    `expand-tilde'
+          If set to `on', tilde expansion is performed when Readline
+          attempts word completion.  The default is `off'.
+
+    `history-preserve-point'
+          If set to `on', the history code attempts to place the point
+          (the current cursor position) at the same location on each
+          history line retrieved with `previous-history' or
+          `next-history'.  The default is `off'.
+
+    `history-size'
+          Set the maximum number of history entries saved in the
+          history list.  If set to zero, the number of entries in the
+          history list is not limited.
+
+    `horizontal-scroll-mode'
+          This variable can be set to either `on' or `off'.  Setting it
+          to `on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  By default, this variable is set to `off'.
+
+    `input-meta'
+          If set to `on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is `off'.  The name `meta-flag' is a synonym
+          for this variable.
+
+    `isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and `C-J' will terminate
+          an incremental search.
+
+    `keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Acceptable `keymap' names are `emacs',
+          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move',
+          `vi-command', and `vi-insert'.  `vi' is equivalent to
+          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
+          default value is `emacs'.  The value of the `editing-mode'
+          variable also affects the default keymap.
+
+    `mark-directories'
+          If set to `on', completed directory names have a slash
+          appended.  The default is `on'.
+
+    `mark-modified-lines'
+          This variable, when set to `on', causes Readline to display an
+          asterisk (`*') at the start of history lines which have been
+          modified.  This variable is `off' by default.
+
+    `mark-symlinked-directories'
+          If set to `on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          `mark-directories').  The default is `off'.
+
+    `match-hidden-files'
+          This variable, when set to `on', causes Readline to match
+          files whose names begin with a `.' (hidden files) when
+          performing filename completion.  If set to `off', the leading
+          `.' must be supplied by the user in the filename to be
+          completed.  This variable is `on' by default.
+
+    `menu-complete-display-prefix'
+          If set to `on', menu completion displays the common prefix of
+          the list of possible completions (which may be empty) before
+          cycling through the list.  The default is `off'.
+
+    `output-meta'
+          If set to `on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is `off'.
+
+    `page-completions'
+          If set to `on', Readline uses an internal `more'-like pager
+          to display a screenful of possible completions at a time.
+          This variable is `on' by default.
+
+    `print-completions-horizontally'
+          If set to `on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is `off'.
+
+    `revert-all-at-newline'
+          If set to `on', Readline will undo all changes to history
+          lines before returning when `accept-line' is executed.  By
+          default, history lines may be modified and retain individual
+          undo lists across calls to `readline'.  The default is `off'.
+
+    `show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to `on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is `off'.
+
+    `show-all-if-unmodified'
+          This alters the default behavior of the completion functions
+          in a fashion similar to SHOW-ALL-IF-AMBIGUOUS.  If set to
+          `on', words which have more than one possible completion
+          without any possible partial completion (the possible
+          completions don't share a common prefix) cause the matches to
+          be listed immediately instead of ringing the bell.  The
+          default value is `off'.
+
+    `skip-completed-text'
+          If set to `on', this alters the default completion behavior
+          when inserting a single match into the line.  It's only
+          active when performing completion in the middle of a word.
+          If enabled, readline does not insert characters from the
+          completion that match characters after point in the word
+          being completed, so portions of the word following the cursor
+          are not duplicated.  For instance, if this is enabled,
+          attempting completion when the cursor is after the `e' in
+          `Makefile' will result in `Makefile' rather than
+          `Makefilefile', assuming there is a single possible
+          completion.  The default value is `off'.
+
+    `visible-stats'
+          If set to `on', a character denoting a file's type is
+          appended to the filename when listing possible completions.
+          The default is `off'.
+
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is
+     simple.  First you need to find the name of the command that you
+     want to change.  The following sections contain tables of the
+     command name, the default keybinding, if any, and a short
+     description of what the command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  There can be no space
+     between the key name and the colon - that will be interpreted as
+     part of the key name.  The name of the key can be expressed in
+     different ways, depending on what you find most comfortable.
+
+     In addition to command names, readline allows keys to be bound to
+     a string that is inserted when the key is pressed (a MACRO).
+
+    KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the above example, `C-u' is bound to the function
+          `universal-argument', `M-DEL' is bound to the function
+          `backward-kill-word', and `C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          `> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+    "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, `C-u' is again bound to the function
+          `universal-argument' (just as it was in the first example),
+          `C-x C-r' is bound to the function `re-read-init-file', and
+          `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function
+          Key 1'.
+
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+    `\C-'
+          control prefix
+
+    `\M-'
+          meta prefix
+
+    `\e'
+          an escape character
+
+    `\\'
+          backslash
+
+    `\"'
+          <">, a double quotation mark
+
+    `\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+    `\a'
+          alert (bell)
+
+    `\b'
+          backspace
+
+    `\d'
+          delete
+
+    `\f'
+          form feed
+
+    `\n'
+          newline
+
+    `\r'
+          carriage return
+
+    `\t'
+          horizontal tab
+
+    `\v'
+          vertical tab
+
+    `\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+
+    `\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including `"' and `''.  For example,
+     the following binding will make `C-x \' insert a single `\' into
+     the line:
+          "\C-x\\": "\\"

+1.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings
+and variable settings to be performed as the result of tests.  There
+are four parser directives used.
+
+`$if'
+     The `$if' construct allows bindings to be made based on the
+     editing mode, the terminal being used, or the application using
+     Readline.  The text of the test extends to the end of the line; no
+     characters are required to isolate it.
+
+    `mode'
+          The `mode=' form of the `$if' directive is used to test
+          whether Readline is in `emacs' or `vi' mode.  This may be
+          used in conjunction with the `set keymap' command, for
+          instance, to set bindings in the `emacs-standard' and
+          `emacs-ctlx' keymaps only if Readline is starting out in
+          `emacs' mode.
+
+    `term'
+          The `term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          `=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first `-'.  This
+          allows `sun' to match both `sun' and `sun-cmd', for instance.
+
+    `application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+`$endif'
+     This command, as seen in the previous example, terminates an `$if'
+     command.
+
+`$else'
+     Commands in this branch of the `$if' directive are executed if the
+     test fails.
+
+`$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from `/etc/inputrc':
+          $include /etc/inputrc

+
+File: readline.info,  Node: Commands For History,  Next: Commands For Text,  Prev: Commands For Moving,  Up: Bindable Readline Commands
+
+1.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+`accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, it may be added to the history list for future recall
+     with `add_history()'.  If this line is a modified history line,
+     the history line is restored to its original state.
+
+`previous-history (C-p)'
+     Move `back' through the history list, fetching the previous
+     command.
+
+`next-history (C-n)'
+     Move `forward' through the history list, fetching the next command.
+
+`beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+`end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+`reverse-search-history (C-r)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary.  This is an incremental search.
+
+`forward-search-history (C-s)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary.  This is an incremental
+     search.
+
+`non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.  Once the
+     argument N is computed, the argument is extracted as if the `!N'
+     history expansion had been specified.
+
+`yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With a numeric argument, behave exactly
+     like `yank-nth-arg'.  Successive calls to `yank-last-arg' move
+     back through the history list, inserting the last word (or the
+     word specified by the argument to the first call) of each line in
+     turn.  Any numeric argument supplied to these successive calls
+     determines the direction to move through the history.  A negative
+     argument switches the direction through the history (back or
+     forward).  The history expansion facilities are used to extract
+     the last argument, as if the `!$' history expansion had been
+     specified.
+

+
+1.4.3 Commands For Changing Text
+--------------------------------
+
+`delete-char (C-d)'
+     Delete the character at point.  If point is at the beginning of
+     the line, there are no characters in the line, and the last
+     character typed was not bound to `delete-char', then return EOF.
+
+`backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+`forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+`quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like `C-q', for example.
+
+`tab-insert (M-<TAB>)'
+     Insert a tab character.
+
+`self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+`transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+`transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+`upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+`downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+`capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+`overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     `emacs' mode; `vi' mode does overwrite differently.  Each call to
+     `readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to `self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to `backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.
+
+
+
+File: readline.info,  Node: Commands For Killing,  Next: Numeric Arguments,  Prev: Commands For Text,  Up: Bindable Readline Commands
+
+1.4.4 Killing And Yanking
+-------------------------
+
+`kill-line (C-k)'
+     Kill the text from point to the end of the line.
+
+`backward-kill-line (C-x Rubout)'
+     Kill backward to the beginning of the line.
+
+`unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+`kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+`kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as `forward-word'.
+
+`backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     `backward-word'.
+
+`unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+`unix-filename-rubout ()'
+     Kill the word behind point, using white space and the slash
+     character as the word boundaries.  The killed text is saved on the
+     kill-ring.
+
+`delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+`kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+`copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+`copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word
+     boundaries are the same as `backward-word'.  By default, this
+     command is unbound.
+
+`copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as `forward-word'.  By default, this
+     command is unbound.
+
+`yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+`yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `yank' or `yank-pop'.
+
+
+File: readline.info,  Node: Numeric Arguments,  Next: Commands For Completion,  Prev: Commands For Killing,  Up: Bindable Readline Commands
+
+1.4.5 Specifying Numeric Arguments
+----------------------------------
+
+`digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  `M--' starts a negative argument.
+
+`universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is
+     followed by digits, executing `universal-argument' again ends the
+     numeric argument, but is otherwise ignored.  As a special case, if
+     this command is immediately followed by a character that is
+     neither a digit or minus sign, the argument count for the next
+     command is multiplied by four.  The argument count is initially
+     one, so executing this function the first time makes the argument
+     count four, a second time makes the argument count sixteen, and so
+     on.  By default, this is not bound to a key.

+
+1.4.6 Letting Readline Type For You
+-----------------------------------
+
+`complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The
+     actual completion performed is application-specific.  The default
+     is filename completion.
+
+`possible-completions (M-?)'
+     List the possible completions of the text before point.  When
+     displaying completions, Readline sets the number of columns used
+     for display to the value of `completion-display-width', the value
+     of the environment variable `COLUMNS', or the screen width, in
+     that order.
+
+`insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by `possible-completions'.
+
+`menu-complete ()'
+     Similar to `complete', but replaces the word to be completed with
+     a single match from the list of possible completions.  Repeated
+     execution of `menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     `bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+`menu-complete-backward ()'
+     Identical to `menu-complete', but moves backward through the list
+     of possible completions, as if `menu-complete' had been given a
+     negative argument.
+
+`delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like `delete-char').  If at the end of the line,
+     behaves identically to `possible-completions'.  This command is
+     unbound by default.

+
+1.4.7 Keyboard Macros
+---------------------
+
+`start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+`end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+`call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+

+
+1.4.8 Some Miscellaneous Commands
+---------------------------------
+
+`re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+`abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of `bell-style').
+
+`do-uppercase-version (M-a, M-b, M-X, ...)'
+     If the metafied character X is lowercase, run the command that is
+     bound to the corresponding uppercase character.
+
+`prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing `<ESC> f' is equivalent to typing `M-f'.
+
+`undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+`revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     `undo' command enough times to get back to the beginning.
+
+`tilde-expand (M-~)'
+     Perform tilde expansion on the current word.
+
+`set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+`exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+`character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative count searches for previous
+     occurrences.
+
+`character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative count searches for subsequent
+     occurrences.
+
+`skip-csi-sequence ()'
+     Read enough characters to consume a multi-key sequence such as
+     those defined for keys like Home and End.  Such sequences begin
+     with a Control Sequence Indicator (CSI), usually ESC-[.  If this
+     sequence is bound to "\e[", keys producing such sequences will
+     have no effect unless explicitly bound to a readline command,
+     instead of inserting stray characters into the editing buffer.
+     This is unbound by default, but usually bound to ESC-[.
+
+`insert-comment (M-#)'
+     Without a numeric argument, the value of the `comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle:  if
+     the characters at the beginning of the line do not match the value
+     of `comment-begin', the value is inserted, otherwise the
+     characters in `comment-begin' are deleted from the beginning of
+     the line.  In either case, the line is accepted as if a newline
+     had been typed.
+
+`dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+`dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`emacs-editing-mode (C-e)'
+     When in `vi' command mode, this causes a switch to `emacs' editing
+     mode.
+
+`vi-editing-mode (M-C-j)'
+     When in `emacs' editing mode, this causes a switch to `vi' editing
+     mode.

+
+1.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of `vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline `vi' mode behaves as specified in the POSIX standard.
+
+   In order to switch interactively between `emacs' and `vi' editing
+modes, use the command `M-C-j' (bound to emacs-editing-mode when in
+`vi' mode and to vi-editing-mode in `emacs' mode).  The Readline
+default is `emacs' mode.
+
+   When you enter a line in `vi' mode, you are already placed in
+`insertion' mode, as if you had typed an `i'.  Pressing <ESC> switches
+you into `command' mode, where you can edit the text of the line with
+the standard `vi' movement keys, move to previous history lines with
+`k' and subsequent lines with `j', and so forth.

+
+2.1 Basic Behavior
+==================
+
+Many programs provide a command line interface, such as `mail', `ftp',
+and `sh'.  For such programs, the default behaviour of Readline is
+sufficient.  This section describes how to use Readline in the simplest
+way possible, perhaps to replace calls in your code to `gets()' or
+`fgets()'.
+
+   The function `readline()' prints a prompt PROMPT and then reads and
+returns a single line of text from the user.  If PROMPT is `NULL' or
+the empty string, no prompt is displayed.  The line `readline' returns
+is allocated with `malloc()'; the caller should `free()' the line when
+it has finished with it.  The declaration for `readline' in ANSI C is
+
+     `char *readline (const char *PROMPT);'
+
+So, one might say
+     `char *line = readline ("Enter a line: ");'
+   in order to read a line of text from the user.  The line returned
+has the final newline removed, so only the text remains.
+
+   If `readline' encounters an `EOF' while reading the line, and the
+line is empty at that point, then `(char *)NULL' is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+   If you want the user to be able to get at the line later, (with
+<C-p> for example), you must call `add_history()' to save the line away
+in a "history" list of such lines.
+
+     `add_history (line)';
+
+For full details on the GNU History Library, see the associated manual.
+
+   It is preferable to avoid saving empty lines on the history list,
+since users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard `gets()' library
+function, and has the advantage of no static buffer to overflow:
+
+     /* A static variable for holding the line. */
+     static char *line_read = (char *)NULL;
+
+     /* Read a string, and return a pointer to it.
+        Returns NULL on EOF. */
+     char *
+     rl_gets ()
+     {
+       /* If the buffer has already been allocated,
+          return the memory to the free pool. */
+       if (line_read)
+         {
+           free (line_read);
+           line_read = (char *)NULL;
+         }
+
+       /* Get a line from the user. */
+       line_read = readline ("");
+
+       /* If the line has any text in it,
+          save it on the history. */
+       if (line_read && *line_read)
+         add_history (line_read);
+
+       return (line_read);
+     }
+
+   This function gives the user the default behaviour of <TAB>
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the <TAB> key with
+`rl_bind_key()'.
+
+     `int rl_bind_key (int KEY, rl_command_func_t *FUNCTION);'
+
+   `rl_bind_key()' takes two arguments: KEY is the character that you
+want to bind, and FUNCTION is the address of the function to call when
+KEY is pressed.  Binding <TAB> to `rl_insert()' makes <TAB> insert
+itself.  `rl_bind_key()' returns non-zero if KEY is not a valid ASCII
+character code (between 0 and 255).
+
+   Thus, to disable the default <TAB> behavior, the following suffices:
+     `rl_bind_key ('\t', rl_insert);'
+
+   This code should be executed once at the start of your program; you
+might write a function called `initialize_readline()' which performs
+this and other desired initializations, such as installing custom
+completers (*note Custom Completers::).

+

+
+2.2 Custom Functions
+====================
+
+Readline provides many functions for manipulating the text of the line,
+but it isn't possible to anticipate the needs of all programs.  This
+section describes the various functions and variables defined within
+the Readline library which allow a user program to add customized
+functionality to Readline.
+
+   Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an application
+writer should include the file `<readline/readline.h>' in any file that
+uses Readline's features.  Since some of the definitions in
+`readline.h' use the `stdio' library, the file `<stdio.h>' should be
+included before `readline.h'.
+
+   `readline.h' defines a C preprocessor variable that should be
+treated as an integer, `RL_READLINE_VERSION', which may be used to
+conditionally compile application code depending on the installed
+Readline version.  The value is a hexadecimal encoding of the major and
+minor version numbers of the library, of the form 0xMMMM.  MM is the
+two-digit major version number; MM is the two-digit minor version
+number.  For Readline 4.2, for example, the value of
+`RL_READLINE_VERSION' would be `0x0402'.

+File: readline.info,  Node: Readline Typedefs,  Next: Function Writing,  Up: Custom Functions
+
+2.2.1 Readline Typedefs
+-----------------------
+
+For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+   The reason for declaring these new types is to make it easier to
+write code describing pointers to C functions with appropriately
+prototyped arguments and return values.
+
+   For instance, say we want to declare a variable FUNC as a pointer to
+a function which takes two `int' arguments and returns an `int' (this
+is the type of all of the Readline bindable functions).  Instead of the
+classic C declaration
+
+   `int (*func)();'
+
+or the ANSI-C style declaration
+
+   `int (*func)(int, int);'
+
+we may write
+
+   `rl_command_func_t *func;'
+
+   The full list of function pointer types available is
+
+`typedef int rl_command_func_t (int, int);'
+
+`typedef char *rl_compentry_func_t (const char *, int);'
+
+`typedef char **rl_completion_func_t (const char *, int, int);'
+
+`typedef char *rl_quote_func_t (char *, int, char *);'
+
+`typedef char *rl_dequote_func_t (char *, int);'
+
+`typedef int rl_compignore_func_t (char **);'
+
+`typedef void rl_compdisp_func_t (char **, int, int);'
+
+`typedef int rl_hook_func_t (void);'
+
+`typedef int rl_getc_func_t (FILE *);'
+
+`typedef int rl_linebuf_func_t (char *, int);'
+
+`typedef int rl_intfunc_t (int);'
+
+`#define rl_ivoidfunc_t rl_hook_func_t'
+
+`typedef int rl_icpfunc_t (char *);'
+
+`typedef int rl_icppfunc_t (char **);'
+
+`typedef void rl_voidfunc_t (void);'
+
+`typedef void rl_vintfunc_t (int);'
+
+`typedef void rl_vcpfunc_t (char *);'
+
+`typedef void rl_vcppfunc_t (char **);'

+
+2.2.2 Writing a New Function
+----------------------------
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+   The calling sequence for a command `foo' looks like
+
+     `int foo (int count, int key)'
+
+where COUNT is the numeric argument (or 1 if defaulted) and KEY is the
+key that invoked this function.
+
+   It is completely up to the function as to what should be done with
+the numeric argument.  Some functions use it as a repeat count, some as
+a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a function uses the numeric argument as a
+repeat count, it should be able to do something useful with both
+negative and positive arguments.  At the very least, it should be aware
+that it can be passed a negative argument.
+
+   A command function should return 0 if its action completes
+successfully, and a non-zero value if some error occurs.  This is the
+convention obeyed by all of the builtin Readline bindable command
+functions.
+

+
+2.3 Readline Variables
+======================
+
+These variables are available to function writers.
+
+ -- Variable: char * rl_line_buffer
+     This is the line gathered so far.  You are welcome to modify the
+     contents of the line, but see *note Allowing Undoing::.  The
+     function `rl_extend_line_buffer' is available to increase the
+     memory allocated to `rl_line_buffer'.
+
+ -- Variable: int rl_point
+     The offset of the current cursor position in `rl_line_buffer' (the
+     _point_).
+
+ -- Variable: int rl_end
+     The number of characters present in `rl_line_buffer'.  When
+     `rl_point' is at the end of the line, `rl_point' and `rl_end' are
+     equal.
+
+ -- Variable: int rl_mark
+     The MARK (saved position) in the current line.  If set, the mark
+     and point define a _region_.
+
+ -- Variable: int rl_done
+     Setting this to a non-zero value causes Readline to return the
+     current line immediately.
+
+ -- Variable: int rl_num_chars_to_read
+     Setting this to a positive value before calling `readline()' causes
+     Readline to return after accepting that many characters, rather
+     than reading up to a character bound to `accept-line'.
+
+ -- Variable: int rl_pending_input
+     Setting this to a value makes it the next keystroke read.  This is
+     a way to stuff a single character into the input stream.
+
+ -- Variable: int rl_dispatching
+     Set to a non-zero value if a function is being called from a key
+     binding; zero otherwise.  Application functions can test this to
+     discover whether they were called directly or by Readline's
+     dispatching mechanism.
+
+ -- Variable: int rl_erase_empty_line
+     Setting this to a non-zero value causes Readline to completely
+     erase the current line, including any prompt, any time a newline
+     is typed as the only character on an otherwise-empty line.  The
+     cursor is moved to the beginning of the newly-blank line.
+
+ -- Variable: char * rl_prompt
+     The prompt Readline uses.  This is set from the argument to
+     `readline()', and should not be assigned to directly.  The
+     `rl_set_prompt()' function (*note Redisplay::) may be used to
+     modify the prompt string after calling `readline()'.
+
+ -- Variable: char * rl_display_prompt
+     The string displayed as the prompt.  This is usually identical to
+     RL_PROMPT, but may be changed temporarily by functions that use
+     the prompt string as a message area, such as incremental search.
+
+ -- Variable: int rl_already_prompted
+     If an application wishes to display the prompt itself, rather than
+     have Readline do it the first time `readline()' is called, it
+     should set this variable to a non-zero value after displaying the
+     prompt.  The prompt must also be passed as the argument to
+     `readline()' so the redisplay functions can update the display
+     properly.  The calling application is responsible for managing the
+     value; Readline never sets it.
+
+ -- Variable: const char * rl_library_version
+     The version number of this revision of the library.
+
+ -- Variable: int rl_readline_version
+     An integer encoding the current version of the library.  The
+     encoding is of the form 0xMMMM, where MM is the two-digit major
+     version number, and MM is the two-digit minor version number.  For
+     example, for Readline-4.2, `rl_readline_version' would have the
+     value 0x0402.
+
+ -- Variable: int rl_gnu_readline_p
+     Always set to 1, denoting that this is GNU readline rather than
+     some emulation.
+
+ -- Variable: const char * rl_terminal_name
+     The terminal type, used for initialization.  If not set by the
+     application, Readline sets this to the value of the `TERM'
+     environment variable the first time it is called.
+
+ -- Variable: const char * rl_readline_name
+     This variable is set to a unique name by each application using
+     Readline.  The value allows conditional parsing of the inputrc file
+     (*note Conditional Init Constructs::).
+
+ -- Variable: FILE * rl_instream
+     The stdio stream from which Readline reads input.  If `NULL',
+     Readline defaults to STDIN.
+
+ -- Variable: FILE * rl_outstream
+     The stdio stream to which Readline performs output.  If `NULL',
+     Readline defaults to STDOUT.
+
+ -- Variable: int rl_prefer_env_winsize
+     If non-zero, Readline gives values found in the `LINES' and
+     `COLUMNS' environment variables greater precedence than values
+     fetched from the kernel when computing the screen dimensions.
+
+ -- Variable: rl_command_func_t * rl_last_func
+     The address of the last command function Readline executed.  May
+     be used to test whether or not a function is being executed twice
+     in succession, for example.
+
+ -- Variable: rl_hook_func_t * rl_startup_hook
+     If non-zero, this is the address of a function to call just before
+     `readline' prints the first prompt.
+
+ -- Variable: rl_hook_func_t * rl_pre_input_hook
+     If non-zero, this is the address of a function to call after the
+     first prompt has been printed and just before `readline' starts
+     reading input characters.
+
+ -- Variable: rl_hook_func_t * rl_event_hook
+     If non-zero, this is the address of a function to call periodically
+     when Readline is waiting for terminal input.  By default, this
+     will be called at most ten times a second if there is no keyboard
+     input.
+
+ -- Variable: rl_getc_func_t * rl_getc_function
+     If non-zero, Readline will call indirectly through this pointer to
+     get a character from the input stream.  By default, it is set to
+     `rl_getc', the default Readline character input function (*note
+     Character Input::).
+
+ -- Variable: rl_voidfunc_t * rl_redisplay_function
+     If non-zero, Readline will call indirectly through this pointer to
+     update the display with the current contents of the editing buffer.
+     By default, it is set to `rl_redisplay', the default Readline
+     redisplay function (*note Redisplay::).
+
+ -- Variable: rl_vintfunc_t * rl_prep_term_function
+     If non-zero, Readline will call indirectly through this pointer to
+     initialize the terminal.  The function takes a single argument, an
+     `int' flag that says whether or not to use eight-bit characters.
+     By default, this is set to `rl_prep_terminal' (*note Terminal
+     Management::).
+
+ -- Variable: rl_voidfunc_t * rl_deprep_term_function
+     If non-zero, Readline will call indirectly through this pointer to
+     reset the terminal.  This function should undo the effects of
+     `rl_prep_term_function'.  By default, this is set to
+     `rl_deprep_terminal' (*note Terminal Management::).
+
+ -- Variable: Keymap rl_executing_keymap
+     This variable is set to the keymap (*note Keymaps::) in which the
+     currently executing readline function was found.
+
+ -- Variable: Keymap rl_binding_keymap
+     This variable is set to the keymap (*note Keymaps::) in which the
+     last key binding occurred.
+
+ -- Variable: char * rl_executing_macro
+     This variable is set to the text of any currently-executing macro.
+
+ -- Variable: int rl_readline_state
+     A variable with bit values that encapsulate the current Readline
+     state.  A bit is set with the `RL_SETSTATE' macro, and unset with
+     the `RL_UNSETSTATE' macro.  Use the `RL_ISSTATE' macro to test
+     whether a particular state bit is set.  Current state bits include:
+
+    `RL_STATE_NONE'
+          Readline has not yet been called, nor has it begun to
+          intialize.
+
+    `RL_STATE_INITIALIZING'
+          Readline is initializing its internal data structures.
+
+    `RL_STATE_INITIALIZED'
+          Readline has completed its initialization.
+
+    `RL_STATE_TERMPREPPED'
+          Readline has modified the terminal modes to do its own input
+          and redisplay.
+
+    `RL_STATE_READCMD'
+          Readline is reading a command from the keyboard.
+
+    `RL_STATE_METANEXT'
+          Readline is reading more input after reading the meta-prefix
+          character.
+
+    `RL_STATE_DISPATCHING'
+          Readline is dispatching to a command.
+
+    `RL_STATE_MOREINPUT'
+          Readline is reading more input while executing an editing
+          command.
+
+    `RL_STATE_ISEARCH'
+          Readline is performing an incremental history search.
+
+    `RL_STATE_NSEARCH'
+          Readline is performing a non-incremental history search.
+
+    `RL_STATE_SEARCH'
+          Readline is searching backward or forward through the history
+          for a string.
+
+    `RL_STATE_NUMERICARG'
+          Readline is reading a numeric argument.
+
+    `RL_STATE_MACROINPUT'
+          Readline is currently getting its input from a
+          previously-defined keyboard macro.
+
+    `RL_STATE_MACRODEF'
+          Readline is currently reading characters defining a keyboard
+          macro.
+
+    `RL_STATE_OVERWRITE'
+          Readline is in overwrite mode.
+
+    `RL_STATE_COMPLETING'
+          Readline is performing word completion.
+
+    `RL_STATE_SIGHANDLER'
+          Readline is currently executing the readline signal handler.
+
+    `RL_STATE_UNDOING'
+          Readline is performing an undo.
+
+    `RL_STATE_INPUTPENDING'
+          Readline has input pending due to a call to
+          `rl_execute_next()'.
+
+    `RL_STATE_TTYCSAVED'
+          Readline has saved the values of the terminal's special
+          characters.
+
+    `RL_STATE_CALLBACK'
+          Readline is currently using the alternate (callback) interface
+          (*note Alternate Interface::).
+
+    `RL_STATE_VIMOTION'
+          Readline is reading the argument to a vi-mode "motion"
+          command.

+
+    `RL_STATE_VICMDONCE'
+          Readline has entered vi command (movement) mode at least one
+          time during the current call to `readline()'.
+
+    `RL_STATE_DONE'
+          Readline has read a key sequence bound to `accept-line' and
+          is about to return the line to the caller.
+
+
+ -- Variable: int rl_explicit_arg
+     Set to a non-zero value if an explicit numeric argument was
+     specified by the user.  Only valid in a bindable command function.
+
+ -- Variable: int rl_numeric_arg
+     Set to the value of any numeric argument explicitly specified by
+     the user before executing the current Readline function.  Only
+     valid in a bindable command function.

+     Set to a value denoting Readline's current editing mode.  A value
+     of 1 means Readline is currently in emacs mode; 0 means that vi
+     mode is active.

+
+2.4.1 Naming a Function
+-----------------------
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+     Meta-Rubout:	backward-kill-word
+
+   This binds the keystroke <Meta-Rubout> to the function
+_descriptively_ named `backward-kill-word'.  You, as the programmer,
+should bind the functions you write to descriptive names as well.
+Readline provides a function for doing that:
+
+ -- Function: int rl_add_defun (const char *name, rl_command_func_t
+          *function, int key)
+     Add NAME to the list of named functions.  Make FUNCTION be the
+     function that gets called.  If KEY is not -1, then bind it to
+     FUNCTION using `rl_bind_key()'.
+
+   Using this function alone is sufficient for most applications.  It
+is the recommended way to add a few functions to the default functions
+that Readline has built in.  If you need to do something other than
+adding a function to Readline, you may need to use the underlying
+functions described below.
+
+
+File: readline.info,  Node: Keymaps,  Next: Binding Keys,  Prev: Function Naming,  Up: Readline Convenience Functions
+
+2.4.2 Selecting a Keymap
+------------------------
+
+Key bindings take place on a "keymap".  The keymap is the association
+between the keys that the user types and the functions that get run.
+You can make your own keymaps, copy existing keymaps, and tell Readline
+which keymap to use.
+
+ -- Function: Keymap rl_make_bare_keymap (void)
+     Returns a new, empty keymap.  The space for the keymap is
+     allocated with `malloc()'; the caller should free it by calling
+     `rl_free_keymap()' when done.
+
+ -- Function: Keymap rl_copy_keymap (Keymap map)
+     Return a new keymap which is a copy of MAP.
+
+ -- Function: Keymap rl_make_keymap (void)
+     Return a new keymap with the printing characters bound to
+     rl_insert, the lowercase Meta characters bound to run their
+     equivalents, and the Meta digits bound to produce numeric
+     arguments.
+
+ -- Function: void rl_discard_keymap (Keymap keymap)
+     Free the storage associated with the data in KEYMAP.  The caller
+     should free KEYMAP.
+
+ -- Function: void rl_free_keymap (Keymap keymap)
+     Free all storage associated with KEYMAP.  This calls
+     `rl_discard_keymap' to free subordindate keymaps and macros.
+
+   Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+ -- Function: Keymap rl_get_keymap (void)
+     Returns the currently active keymap.
+
+ -- Function: void rl_set_keymap (Keymap keymap)
+     Makes KEYMAP the currently active keymap.
+
+ -- Function: Keymap rl_get_keymap_by_name (const char *name)
+     Return the keymap matching NAME.  NAME is one which would be
+     supplied in a `set keymap' inputrc line (*note Readline Init
+     File::).
+
+ -- Function: char * rl_get_keymap_name (Keymap keymap)
+     Return the name matching KEYMAP.  NAME is one which would be
+     supplied in a `set keymap' inputrc line (*note Readline Init
+     File::).
+
+
+File: readline.info,  Node: Binding Keys,  Next: Associating Function Names and Bindings,  Prev: Keymaps,  Up: Readline Convenience Functions
+
+2.4.3 Binding Keys
+------------------
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: `emacs_standard_keymap',
+`emacs_meta_keymap', `emacs_ctlx_keymap', `vi_movement_keymap', and
+`vi_insertion_keymap'.  `emacs_standard_keymap' is the default, and the
+examples in this manual assume that.
+
+   Since `readline()' installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to `readline()' will be overridden.  An
+alternate mechanism is to install custom key bindings in an
+initialization function assigned to the `rl_startup_hook' variable
+(*note Readline Variables::).
+
+   These functions manage key bindings.
+
+ -- Function: int rl_bind_key (int key, rl_command_func_t *function)
+     Binds KEY to FUNCTION in the currently active keymap.  Returns
+     non-zero in the case of an invalid KEY.
+
+ -- Function: int rl_bind_key_in_map (int key, rl_command_func_t
+          *function, Keymap map)
+     Bind KEY to FUNCTION in MAP.  Returns non-zero in the case of an
+     invalid KEY.
+
+ -- Function: int rl_bind_key_if_unbound (int key, rl_command_func_t
+          *function)
+     Binds KEY to FUNCTION if it is not already bound in the currently
+     active keymap.  Returns non-zero in the case of an invalid KEY or
+     if KEY is already bound.
+
+ -- Function: int rl_bind_key_if_unbound_in_map (int key,
+          rl_command_func_t *function, Keymap map)
+     Binds KEY to FUNCTION if it is not already bound in MAP.  Returns
+     non-zero in the case of an invalid KEY or if KEY is already bound.
+
+ -- Function: int rl_unbind_key (int key)
+     Bind KEY to the null function in the currently active keymap.
+     Returns non-zero in case of error.
+
+ -- Function: int rl_unbind_key_in_map (int key, Keymap map)
+     Bind KEY to the null function in MAP.  Returns non-zero in case of
+     error.
+
+ -- Function: int rl_unbind_function_in_map (rl_command_func_t
+          *function, Keymap map)
+     Unbind all keys that execute FUNCTION in MAP.
+
+ -- Function: int rl_unbind_command_in_map (const char *command, Keymap
+          map)
+     Unbind all keys that are bound to COMMAND in MAP.
+
+ -- Function: int rl_bind_keyseq (const char *keyseq, rl_command_func_t
+          *function)
+     Bind the key sequence represented by the string KEYSEQ to the
+     function FUNCTION, beginning in the current keymap.  This makes
+     new keymaps as necessary.  The return value is non-zero if KEYSEQ
+     is invalid.
+
+ -- Function: int rl_bind_keyseq_in_map (const char *keyseq,
+          rl_command_func_t *function, Keymap map)
+     Bind the key sequence represented by the string KEYSEQ to the
+     function FUNCTION.  This makes new keymaps as necessary.  Initial
+     bindings are performed in MAP.  The return value is non-zero if
+     KEYSEQ is invalid.
+
+ -- Function: int rl_set_key (const char *keyseq, rl_command_func_t
+          *function, Keymap map)
+     Equivalent to `rl_bind_keyseq_in_map'.
+
+ -- Function: int rl_bind_keyseq_if_unbound (const char *keyseq,
+          rl_command_func_t *function)
+     Binds KEYSEQ to FUNCTION if it is not already bound in the
+     currently active keymap.  Returns non-zero in the case of an
+     invalid KEYSEQ or if KEYSEQ is already bound.
+
+ -- Function: int rl_bind_keyseq_if_unbound_in_map (const char *keyseq,
+          rl_command_func_t *function, Keymap map)
+     Binds KEYSEQ to FUNCTION if it is not already bound in MAP.
+     Returns non-zero in the case of an invalid KEYSEQ or if KEYSEQ is
+     already bound.
+
+ -- Function: int rl_generic_bind (int type, const char *keyseq, char
+          *data, Keymap map)
+     Bind the key sequence represented by the string KEYSEQ to the
+     arbitrary pointer DATA.  TYPE says what kind of data is pointed to
+     by DATA; this can be a function (`ISFUNC'), a macro (`ISMACR'), or
+     a keymap (`ISKMAP').  This makes new keymaps as necessary.  The
+     initial keymap in which to do bindings is MAP.
+
+ -- Function: int rl_parse_and_bind (char *line)
+     Parse LINE as if it had been read from the `inputrc' file and
+     perform any key bindings and variable assignments found (*note
+     Readline Init File::).
+
+ -- Function: int rl_read_init_file (const char *filename)
+     Read keybindings and variable assignments from FILENAME (*note
+     Readline Init File::).

+2.4.4 Associating Function Names and Bindings
+---------------------------------------------
+
+These functions allow you to find out what keys invoke named functions
+and the functions invoked by a particular key sequence.  You may also
+associate a new function name with an arbitrary function.
+
+ -- Function: rl_command_func_t * rl_named_function (const char *name)
+     Return the function with name NAME.
+
+ -- Function: rl_command_func_t * rl_function_of_keyseq (const char
+          *keyseq, Keymap map, int *type)
+     Return the function invoked by KEYSEQ in keymap MAP.  If MAP is
+     `NULL', the current keymap is used.  If TYPE is not `NULL', the
+     type of the object is returned in the `int' variable it points to
+     (one of `ISFUNC', `ISKMAP', or `ISMACR').
+
+ -- Function: char ** rl_invoking_keyseqs (rl_command_func_t *function)
+     Return an array of strings representing the key sequences used to
+     invoke FUNCTION in the current keymap.
+
+ -- Function: char ** rl_invoking_keyseqs_in_map (rl_command_func_t
+          *function, Keymap map)
+     Return an array of strings representing the key sequences used to
+     invoke FUNCTION in the keymap MAP.
+
+ -- Function: void rl_function_dumper (int readable)
+     Print the readline function names and the key sequences currently
+     bound to them to `rl_outstream'.  If READABLE is non-zero, the
+     list is formatted in such a way that it can be made part of an
+     `inputrc' file and re-read.
+
+ -- Function: void rl_list_funmap_names (void)
+     Print the names of all bindable Readline functions to
+     `rl_outstream'.
+
+ -- Function: const char ** rl_funmap_names (void)
+     Return a NULL terminated array of known function names.  The array
+     is sorted.  The array itself is allocated, but not the strings
+     inside.  You should free the array, but not the pointers, using
+     `free' or `rl_free' when you are done.
+
+ -- Function: int rl_add_funmap_entry (const char *name,
+          rl_command_func_t *function)
+     Add NAME to the list of bindable Readline command names, and make
+     FUNCTION the function to be called when NAME is invoked.

+
+2.4.5 Allowing Undoing
+----------------------
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try something if
+you know you can undo it.
+
+   If your function simply inserts text once, or deletes text once, and
+uses `rl_insert_text()' or `rl_delete_text()' to do it, then undoing is
+already done for you automatically.
+
+   If you do multiple insertions or multiple deletions, or any
+combination of these operations, you should group them together into
+one operation.  This is done with `rl_begin_undo_group()' and
+`rl_end_undo_group()'.
+
+   The types of events that can be undone are:
+
+     enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
+
+   Notice that `UNDO_DELETE' means to insert some text, and
+`UNDO_INSERT' means to delete some text.  That is, the undo code tells
+what to undo, not how to undo it.  `UNDO_BEGIN' and `UNDO_END' are tags
+added by `rl_begin_undo_group()' and `rl_end_undo_group()'.
+
+ -- Function: int rl_begin_undo_group (void)
+     Begins saving undo information in a group construct.  The undo
+     information usually comes from calls to `rl_insert_text()' and
+     `rl_delete_text()', but could be the result of calls to
+     `rl_add_undo()'.
+
+ -- Function: int rl_end_undo_group (void)
+     Closes the current undo group started with `rl_begin_undo_group
+     ()'.  There should be one call to `rl_end_undo_group()' for each
+     call to `rl_begin_undo_group()'.
+
+ -- Function: void rl_add_undo (enum undo_code what, int start, int
+          end, char *text)
+     Remember how to undo an event (according to WHAT).  The affected
+     text runs from START to END, and encompasses TEXT.
+
+ -- Function: void rl_free_undo_list (void)
+     Free the existing undo list.
+
+ -- Function: int rl_do_undo (void)
+     Undo the first thing on the undo list.  Returns `0' if there was
+     nothing to undo, non-zero if something was undone.
+
+   Finally, if you neither insert nor delete text, but directly modify
+the existing text (e.g., change its case), call `rl_modifying()' once,
+just before you modify the text.  You must supply the indices of the
+text range that you are going to modify.
+
+ -- Function: int rl_modifying (int start, int end)
+     Tell Readline to save the text between START and END as a single
+     undo unit.  It is assumed that you will subsequently modify that
+     text.

+
+2.4.6 Redisplay
+---------------
+
+ -- Function: void rl_redisplay (void)
+     Change what's displayed on the screen to reflect the current
+     contents of `rl_line_buffer'.
+
+ -- Function: int rl_forced_update_display (void)
+     Force the line to be updated and redisplayed, whether or not
+     Readline thinks the screen display is correct.
+
+ -- Function: int rl_on_new_line (void)
+     Tell the update functions that we have moved onto a new (empty)
+     line, usually after ouputting a newline.
+
+ -- Function: int rl_on_new_line_with_prompt (void)
+     Tell the update functions that we have moved onto a new line, with
+     RL_PROMPT already displayed.  This could be used by applications
+     that want to output the prompt string themselves, but still need
+     Readline to know the prompt string length for redisplay.  It
+     should be used after setting RL_ALREADY_PROMPTED.
+
+ -- Function: int rl_reset_line_state (void)
+     Reset the display state to a clean state and redisplay the current
+     line starting on a new line.
+
+ -- Function: int rl_crlf (void)
+     Move the cursor to the start of the next screen line.
+
+ -- Function: int rl_show_char (int c)
+     Display character C on `rl_outstream'.  If Readline has not been
+     set to display meta characters directly, this will convert meta
+     characters to a meta-prefixed key sequence.  This is intended for
+     use by applications which wish to do their own redisplay.
+
+ -- Function: int rl_message (const char *, ...)
+     The arguments are a format string as would be supplied to `printf',
+     possibly containing conversion specifications such as `%d', and
+     any additional arguments necessary to satisfy the conversion
+     specifications.  The resulting string is displayed in the "echo
+     area".  The echo area is also used to display numeric arguments
+     and search strings.  You should call `rl_save_prompt' to save the
+     prompt information before calling this function.
+
+ -- Function: int rl_clear_message (void)
+     Clear the message in the echo area.  If the prompt was saved with
+     a call to `rl_save_prompt' before the last call to `rl_message',
+     call `rl_restore_prompt' before calling this function.
+
+ -- Function: void rl_save_prompt (void)
+     Save the local Readline prompt display state in preparation for
+     displaying a new message in the message area with `rl_message()'.
+
+ -- Function: void rl_restore_prompt (void)
+     Restore the local Readline prompt display state saved by the most
+     recent call to `rl_save_prompt'.  if `rl_save_prompt' was called
+     to save the prompt before a call to `rl_message', this function
+     should be called before the corresponding call to
+     `rl_clear_message'.
+
+ -- Function: int rl_expand_prompt (char *prompt)
+     Expand any special character sequences in PROMPT and set up the
+     local Readline prompt redisplay variables.  This function is
+     called by `readline()'.  It may also be called to expand the
+     primary prompt if the `rl_on_new_line_with_prompt()' function or
+     `rl_already_prompted' variable is used.  It returns the number of
+     visible characters on the last line of the (possibly multi-line)
+     prompt.  Applications may indicate that the prompt contains
+     characters that take up no physical screen space when displayed by
+     bracketing a sequence of such characters with the special markers
+     `RL_PROMPT_START_IGNORE' and `RL_PROMPT_END_IGNORE' (declared in
+     `readline.h'.  This may be used to embed terminal-specific escape
+     sequences in prompts.
+
+ -- Function: int rl_set_prompt (const char *prompt)
+     Make Readline use PROMPT for subsequent redisplay.  This calls
+     `rl_expand_prompt()' to expand the prompt and sets `rl_prompt' to
+     the result.

+
+2.4.7 Modifying Text
+--------------------
+
+ -- Function: int rl_insert_text (const char *text)
+     Insert TEXT into the line at the current cursor position.  Returns
+     the number of characters inserted.
+
+ -- Function: int rl_delete_text (int start, int end)
+     Delete the text between START and END in the current line.
+     Returns the number of characters deleted.
+
+ -- Function: char * rl_copy_text (int start, int end)
+     Return a copy of the text between START and END in the current
+     line.
+
+ -- Function: int rl_kill_text (int start, int end)
+     Copy the text between START and END in the current line to the
+     kill ring, appending or prepending to the last kill if the last
+     command was a kill command.  The text is deleted.  If START is
+     less than END, the text is appended, otherwise prepended.  If the
+     last command was not a kill, a new kill ring slot is used.
+
+ -- Function: int rl_push_macro_input (char *macro)
+     Cause MACRO to be inserted into the line, as if it had been invoked
+     by a key bound to a macro.  Not especially useful; use
+     `rl_insert_text()' instead.
+
+
+File: readline.info,  Node: Character Input,  Next: Terminal Management,  Prev: Modifying Text,  Up: Readline Convenience Functions
+
+2.4.8 Character Input
+---------------------
+
+ -- Function: int rl_read_key (void)
+     Return the next character available from Readline's current input
+     stream.  This handles input inserted into the input stream via
+     RL_PENDING_INPUT (*note Readline Variables::) and
+     `rl_stuff_char()', macros, and characters read from the keyboard.
+     While waiting for input, this function will call any function
+     assigned to the `rl_event_hook' variable.
+
+ -- Function: int rl_getc (FILE *stream)
+     Return the next character available from STREAM, which is assumed
+     to be the keyboard.
+
+ -- Function: int rl_stuff_char (int c)
+     Insert C into the Readline input stream.  It will be "read" before
+     Readline attempts to read characters from the terminal with
+     `rl_read_key()'.  Up to 512 characters may be pushed back.
+     `rl_stuff_char' returns 1 if the character was successfully
+     inserted; 0 otherwise.
+
+ -- Function: int rl_execute_next (int c)
+     Make C be the next command to be executed when `rl_read_key()' is
+     called.  This sets RL_PENDING_INPUT.
+
+ -- Function: int rl_clear_pending_input (void)
+     Unset RL_PENDING_INPUT, effectively negating the effect of any
+     previous call to `rl_execute_next()'.  This works only if the
+     pending input has not already been read with `rl_read_key()'.
+
+ -- Function: int rl_set_keyboard_input_timeout (int u)
+     While waiting for keyboard input in `rl_read_key()', Readline will
+     wait for U microseconds for input before calling any function
+     assigned to `rl_event_hook'.  U must be greater than or equal to
+     zero (a zero-length timeout is equivalent to a poll).  The default
+     waiting period is one-tenth of a second.  Returns the old timeout
+     value.

+2.4.9 Terminal Management
+-------------------------
+
+ -- Function: void rl_prep_terminal (int meta_flag)
+     Modify the terminal settings for Readline's use, so `readline()'
+     can read a single character at a time from the keyboard.  The
+     META_FLAG argument should be non-zero if Readline should read
+     eight-bit input.
+
+ -- Function: void rl_deprep_terminal (void)
+     Undo the effects of `rl_prep_terminal()', leaving the terminal in
+     the state in which it was before the most recent call to
+     `rl_prep_terminal()'.
+
+ -- Function: void rl_tty_set_default_bindings (Keymap kmap)
+     Read the operating system's terminal editing characters (as would
+     be displayed by `stty') to their Readline equivalents.  The
+     bindings are performed in KMAP.
+
+ -- Function: void rl_tty_unset_default_bindings (Keymap kmap)
+     Reset the bindings manipulated by `rl_tty_set_default_bindings' so
+     that the terminal editing characters are bound to `rl_insert'.
+     The bindings are performed in KMAP.
+
+ -- Function: int rl_reset_terminal (const char *terminal_name)
+     Reinitialize Readline's idea of the terminal settings using
+     TERMINAL_NAME as the terminal type (e.g., `vt100').  If
+     TERMINAL_NAME is `NULL', the value of the `TERM' environment
+     variable is used.

+2.4.10 Utility Functions
+------------------------
+
+ -- Function: int rl_save_state (struct readline_state *sp)
+     Save a snapshot of Readline's internal state to SP.  The contents
+     of the READLINE_STATE structure are documented in `readline.h'.
+     The caller is responsible for allocating the structure.
+
+ -- Function: int rl_restore_state (struct readline_state *sp)
+     Restore Readline's internal state to that stored in SP, which must
+     have been saved by a call to `rl_save_state'.  The contents of the
+     READLINE_STATE structure are documented in `readline.h'.  The
+     caller is responsible for freeing the structure.
+
+ -- Function: void rl_free (void *mem)
+     Deallocate the memory pointed to by MEM.  MEM must have been
+     allocated by `malloc'.
+
+ -- Function: void rl_replace_line (const char *text, int clear_undo)
+     Replace the contents of `rl_line_buffer' with TEXT.  The point and
+     mark are preserved, if possible.  If CLEAR_UNDO is non-zero, the
+     undo list associated with the current line is cleared.
+
+ -- Function: void rl_extend_line_buffer (int len)
+     Ensure that `rl_line_buffer' has enough space to hold LEN
+     characters, possibly reallocating it if necessary.
+
+ -- Function: int rl_initialize (void)
+     Initialize or re-initialize Readline's internal state.  It's not
+     strictly necessary to call this; `readline()' calls it before
+     reading any input.
+
+ -- Function: int rl_ding (void)
+     Ring the terminal bell, obeying the setting of `bell-style'.

+
+ -- Function: void rl_display_match_list (char **matches, int len, int
+          max)
+     A convenience function for displaying a list of strings in

+     of strings, in argv format, such as a list of completion matches.
+     `len' is the number of strings in `matches', and `max' is the
+     length of the longest string in `matches'.  This function uses the
+     setting of `print-completions-horizontally' to select how the
+     matches are displayed (*note Readline Init File Syntax::).  When
+     displaying completions, this function sets the number of columns
+     used for display to the value of `completion-display-width', the
+     value of the environment variable `COLUMNS', or the screen width,
+     in that order.
+
+   The following are implemented as macros, defined in `chardefs.h'.
+Applications should refrain from using them.
+
+ -- Function: int _rl_uppercase_p (int c)
+     Return 1 if C is an uppercase alphabetic character.
+
+ -- Function: int _rl_lowercase_p (int c)

+     If C is an uppercase alphabetic character, return the corresponding
+     lowercase character.
+
+ -- Function: int _rl_digit_value (int c)
+     If C is a number, return the value it represents.

+------------------------------
+
+ -- Function: int rl_macro_bind (const char *keyseq, const char *macro,
+          Keymap map)
+     Bind the key sequence KEYSEQ to invoke the macro MACRO.  The
+     binding is performed in MAP.  When KEYSEQ is invoked, the MACRO
+     will be inserted into the line.  This function is deprecated; use
+     `rl_generic_bind()' instead.
+
+ -- Function: void rl_macro_dumper (int readable)
+     Print the key sequences bound to macros and their values, using
+     the current keymap, to `rl_outstream'.  If READABLE is non-zero,
+     the list is formatted in such a way that it can be made part of an
+     `inputrc' file and re-read.
+
+ -- Function: int rl_variable_bind (const char *variable, const char
+          *value)
+     Make the Readline variable VARIABLE have VALUE.  This behaves as
+     if the readline command `set VARIABLE VALUE' had been executed in
+     an `inputrc' file (*note Readline Init File Syntax::).
+
+ -- Function: char * rl_variable_value (const char *variable)
+     Return a string representing the value of the Readline variable
+     VARIABLE.  For boolean variables, this string is either `on' or
+     `off'.
+
+ -- Function: void rl_variable_dumper (int readable)
+     Print the readline variable names and their current values to
+     `rl_outstream'.  If READABLE is non-zero, the list is formatted in

+     re-read.
+
+ -- Function: int rl_set_paren_blink_timeout (int u)
+     Set the time interval (in microseconds) that Readline waits when
+     showing a balancing character when `blink-matching-paren' has been
+     enabled.
+
+ -- Function: char * rl_get_termcap (const char *cap)
+     Retrieve the string value of the termcap capability CAP.  Readline
+     fetches the termcap entry for the current terminal name and uses
+     those capabilities to move around the screen line and perform other
+     terminal-specific operations, like erasing a line.  Readline does
+     not use all of a terminal's capabilities, and this function will
+     return values for only those capabilities Readline uses.

+
+2.4.12 Alternate Interface
+--------------------------
+
+An alternate interface is available to plain `readline()'.  Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to `select()' on
+various file descriptors.  To accomodate this need, readline can also
+be invoked as a `callback' function from an event loop.  There are
+functions available to make this easy.
+
+ -- Function: void rl_callback_handler_install (const char *prompt,
+          rl_vcpfunc_t *lhandler)
+     Set up the terminal for readline I/O and display the initial
+     expanded value of PROMPT.  Save the value of LHANDLER to use as a
+     function to call when a complete line of input has been entered.
+     The function takes the text of the line as an argument.
+
+ -- Function: void rl_callback_read_char (void)
+     Whenever an application determines that keyboard input is
+     available, it should call `rl_callback_read_char()', which will
+     read the next character from the current input source.  If that
+     character completes the line, `rl_callback_read_char' will invoke
+     the LHANDLER function saved by `rl_callback_handler_install' to
+     process the line.  Before calling the LHANDLER function, the
+     terminal settings are reset to the values they had before calling
+     `rl_callback_handler_install'.  If the LHANDLER function returns,
+     the terminal settings are modified for Readline's use again.
+     `EOF' is  indicated by calling LHANDLER with a `NULL' line.
+
+ -- Function: void rl_callback_handler_remove (void)
+     Restore the terminal to its initial state and remove the line
+     handler.  This may be called from within a callback as well as
+     independently.  If the LHANDLER installed by
+     `rl_callback_handler_install' does not exit the program, either
+     this function or the function referred to by the value of
+     `rl_deprep_term_function' should be called before the program
+     exits to reset the terminal settings.

+
+2.5 Readline Signal Handling
+============================
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his
+terminal, or a network connection being broken.  There is a class of
+signals that can be sent to the process currently reading input from
+the keyboard.  Since Readline changes the terminal attributes when it
+is called, it needs to perform special processing when such a signal is
+received in order to restore the terminal to a sane state, or provide
+application writers with functions to do so manually.
+
+   Readline contains an internal signal handler that is installed for a
+number of signals (`SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM',
+`SIGTSTP', `SIGTTIN', and `SIGTTOU').  When one of these signals is
+received, the signal handler will reset the terminal attributes to
+those that were in effect before `readline()' was called, reset the
+signal handling to what it was before `readline()' was called, and
+resend the signal to the calling application.  If and when the calling
+application's signal handler returns, Readline will reinitialize the
+terminal and continue to accept input.  When a `SIGINT' is received,
+the Readline signal handler performs some additional work, which will
+cause any partially-entered line to be aborted (see the description of
+`rl_free_line_state()' below).
+
+   There is an additional Readline signal handler, for `SIGWINCH', which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an `xterm').  The Readline `SIGWINCH'
+handler updates Readline's internal screen size information, and then
+calls any `SIGWINCH' signal handler the calling application has
+installed.  Readline calls the application's `SIGWINCH' signal handler
+without resetting the terminal to its original state.  If the
+application's signal handler does more than update its idea of the
+terminal size and return (for example, a `longjmp' back to a main
+processing loop), it _must_ call `rl_cleanup_after_signal()' (described
+below), to restore the terminal state.
+
+   Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling `readline()', not in a
+signal handler, so Readline's internal signal state is not corrupted.
+
+ -- Variable: int rl_catch_signals
+     If this variable is non-zero, Readline will install signal
+     handlers for `SIGINT', `SIGQUIT', `SIGTERM', `SIGALRM', `SIGTSTP',
+     `SIGTTIN', and `SIGTTOU'.
+
+     The default value of `rl_catch_signals' is 1.
+
+ -- Variable: int rl_catch_sigwinch
+     If this variable is non-zero, Readline will install a signal
+     handler for `SIGWINCH'.
+
+     The default value of `rl_catch_sigwinch' is 1.
+
+   If an application does not wish to have Readline catch any signals,
+or to handle signals other than those Readline catches (`SIGHUP', for
+example), Readline provides convenience functions to do the necessary
+terminal and internal state cleanup upon receipt of a signal.
+
+ -- Function: void rl_cleanup_after_signal (void)
+     This function will reset the state of the terminal to what it was
+     before `readline()' was called, and remove the Readline signal
+     handlers for all signals, depending on the values of
+     `rl_catch_signals' and `rl_catch_sigwinch'.
+
+ -- Function: void rl_free_line_state (void)
+     This will free any partial state associated with the current input
+     line (undo information, any partial history entry, any
+     partially-entered keyboard macro, and any partially-entered
+     numeric argument).  This should be called before
+     `rl_cleanup_after_signal()'.  The Readline signal handler for
+     `SIGINT' calls this to abort the current input line.
+
+ -- Function: void rl_reset_after_signal (void)
+     This will reinitialize the terminal and reinstall any Readline
+     signal handlers, depending on the values of `rl_catch_signals' and
+     `rl_catch_sigwinch'.
+
+   If an application does not wish Readline to catch `SIGWINCH', it may
+call `rl_resize_terminal()' or `rl_set_screen_size()' to force Readline
+to update its idea of the terminal size when a `SIGWINCH' is received.
+
+ -- Function: void rl_echo_signal_char (int sig)
+     If an application wishes to install its own signal handlers, but
+     still have readline display characters that generate signals,
+     calling this function with SIG set to `SIGINT', `SIGQUIT', or
+     `SIGTSTP' will display the character generating that signal.
+
+ -- Function: void rl_resize_terminal (void)
+     Update Readline's internal screen size by reading values from the
+     kernel.
+
+ -- Function: void rl_set_screen_size (int rows, int cols)
+     Set Readline's idea of the terminal size to ROWS rows and COLS
+     columns.  If either ROWS or COLUMNS is less than or equal to 0,
+     Readline's idea of that terminal dimension is unchanged.
+
+   If an application does not want to install a `SIGWINCH' handler, but
+is still interested in the screen dimensions, Readline's idea of the
+screen size may be queried.
+
+ -- Function: void rl_get_screen_size (int *rows, int *cols)
+     Return Readline's idea of the terminal's size in the variables
+     pointed to by the arguments.
+
+ -- Function: void rl_reset_screen_size (void)
+     Cause Readline to reobtain the screen size and recalculate its
+     dimensions.
+
+   The following functions install and remove Readline's signal
+handlers.
+
+ -- Function: int rl_set_signals (void)
+     Install Readline's signal handler for `SIGINT', `SIGQUIT',
+     `SIGTERM', `SIGALRM', `SIGTSTP', `SIGTTIN', `SIGTTOU', and
+     `SIGWINCH', depending on the values of `rl_catch_signals' and
+     `rl_catch_sigwinch'.
+
+ -- Function: int rl_clear_signals (void)
+     Remove all of the Readline signal handlers installed by
+     `rl_set_signals()'.

+2.6 Custom Completers
+=====================
+
+Typically, a program that reads commands from the user has a way of
+disambiguating commands and data.  If your program is one of these, then
+it can provide completion for commands, data, or both.  The following
+sections describe how your program and Readline cooperate to provide
+this service.
+
+* Menu:
+
+* How Completing Works::	The logic used to do completion.
+* Completion Functions::	Functions provided by Readline.
+* Completion Variables::	Variables which control completion.
+* A Short Completion Example::	An example of writing completer subroutines.
+
+
+File: readline.info,  Node: How Completing Works,  Next: Completion Functions,  Up: Custom Completers
+
+2.6.1 How Completing Works
+--------------------------
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately expand a
+partial word without knowing all of the possible words which make sense
+in that context.  The Readline library provides the user interface to
+completion, and two of the most common completion functions:  filename
+and username.  For completing other types of text, you must write your
+own completion function.  This section describes exactly what such
+functions must do, and provides an example.
+
+   There are three major functions used to perform completion:
+
+  1. The user-interface function `rl_complete()'.  This function is
+     called with the same arguments as other bindable Readline
+     functions: COUNT and INVOKING_KEY.  It isolates the word to be
+     completed and calls `rl_completion_matches()' to generate a list
+     of possible completions.  It then either lists the possible
+     completions, inserts the possible completions, or actually
+     performs the completion, depending on which behavior is desired.
+
+  2. The internal function `rl_completion_matches()' uses an
+     application-supplied "generator" function to generate the list of
+     possible matches, and then returns the array of these matches.
+     The caller should place the address of its generator function in
+     `rl_completion_entry_function'.
+
+  3. The generator function is called repeatedly from
+     `rl_completion_matches()', returning a string each time.  The
+     arguments to the generator function are TEXT and STATE.  TEXT is
+     the partial word to be completed.  STATE is zero the first time
+     the function is called, allowing the generator to perform any
+     necessary initialization, and a positive non-zero integer for each
+     subsequent call.  The generator function returns `(char *)NULL' to
+     inform `rl_completion_matches()' that there are no more
+     possibilities left.  Usually the generator function computes the
+     list of possible completions when STATE is zero, and returns them
+     one at a time on subsequent calls.  Each string the generator
+     function returns as a match must be allocated with `malloc()';
+     Readline frees the strings when it has finished with them.  Such a
+     generator function is referred to as an "application-specific
+     completion function".
+
+
+ -- Function: int rl_complete (int ignore, int invoking_key)
+     Complete the word at or before point.  You have supplied the
+     function that does the initial simple matching selection algorithm
+     (see `rl_completion_matches()').  The default is to do filename
+     completion.
+
+ -- Variable: rl_compentry_func_t * rl_completion_entry_function
+     This is a pointer to the generator function for
+     `rl_completion_matches()'.  If the value of
+     `rl_completion_entry_function' is `NULL' then the default filename
+     generator function, `rl_filename_completion_function()', is used.
+     An "application-specific completion function" is a function whose
+     address is assigned to `rl_completion_entry_function' and whose
+     return values are used to  generate possible completions.
+

+
+2.6.2 Completion Functions
+--------------------------
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+ -- Function: int rl_complete_internal (int what_to_do)
+     Complete the word at or before point.  WHAT_TO_DO says what to do
+     with the completion.  A value of `?' means list the possible
+     completions.  `TAB' means do standard completion.  `*' means
+     insert all of the possible completions.  `!' means to display all
+     of the possible completions, if there is more than one, as well as
+     performing partial completion.  `@' is similar to `!', but
+     possible completions are not listed if the possible completions
+     share a common prefix.
+
+ -- Function: int rl_complete (int ignore, int invoking_key)
+     Complete the word at or before point.  You have supplied the
+     function that does the initial simple matching selection algorithm
+     (see `rl_completion_matches()' and `rl_completion_entry_function').
+     The default is to do filename completion.  This calls
+     `rl_complete_internal()' with an argument depending on
+     INVOKING_KEY.
+
+ -- Function: int rl_possible_completions (int count, int invoking_key)
+     List the possible completions.  See description of `rl_complete
+     ()'.  This calls `rl_complete_internal()' with an argument of `?'.
+
+ -- Function: int rl_insert_completions (int count, int invoking_key)
+     Insert the list of possible completions into the line, deleting the
+     partially-completed word.  See description of `rl_complete()'.
+     This calls `rl_complete_internal()' with an argument of `*'.
+
+ -- Function: int rl_completion_mode (rl_command_func_t *cfunc)
+     Returns the apppriate value to pass to `rl_complete_internal()'
+     depending on whether CFUNC was called twice in succession and the
+     values of the `show-all-if-ambiguous' and `show-all-if-unmodified'
+     variables.  Application-specific completion functions may use this
+     function to present the same interface as `rl_complete()'.
+
+ -- Function: char ** rl_completion_matches (const char *text,
+          rl_compentry_func_t *entry_func)
+     Returns an array of strings which is a list of completions for
+     TEXT.  If there are no completions, returns `NULL'.  The first
+     entry in the returned array is the substitution for TEXT.  The
+     remaining entries are the possible completions.  The array is
+     terminated with a `NULL' pointer.
+
+     ENTRY_FUNC is a function of two args, and returns a `char *'.  The
+     first argument is TEXT.  The second is a state argument; it is
+     zero on the first call, and non-zero on subsequent calls.
+     ENTRY_FUNC returns a `NULL'  pointer to the caller when there are
+     no more matches.
+
+ -- Function: char * rl_filename_completion_function (const char *text,
+          int state)
+     A generator function for filename completion in the general case.
+     TEXT is a partial filename.  The Bash source is a useful reference
+     for writing application-specific completion functions (the Bash
+     completion functions call this and other Readline functions).
+
+ -- Function: char * rl_username_completion_function (const char *text,
+          int state)
+     A completion generator for usernames.  TEXT contains a partial
+     username preceded by a random character (usually `~').  As with all
+     completion generators, STATE is zero on the first call and non-zero
+     for subsequent calls.

+
+2.6.3 Completion Variables
+--------------------------
+
+ -- Variable: rl_compentry_func_t * rl_completion_entry_function
+     A pointer to the generator function for `rl_completion_matches()'.
+     `NULL' means to use `rl_filename_completion_function()', the
+     default filename completer.
+
+ -- Variable: rl_completion_func_t * rl_attempted_completion_function
+     A pointer to an alternative function to create matches.  The
+     function is called with TEXT, START, and END.  START and END are
+     indices in `rl_line_buffer' defining the boundaries of TEXT, which
+     is a character string.  If this function exists and returns
+     `NULL', or if this variable is set to `NULL', then `rl_complete()'
+     will call the value of `rl_completion_entry_function' to generate
+     matches, otherwise the array of strings returned will be used.  If
+     this function sets the `rl_attempted_completion_over' variable to
+     a non-zero value, Readline will not perform its default completion
+     even if this function returns no matches.
+
+ -- Variable: rl_quote_func_t * rl_filename_quoting_function
+     A pointer to a function that will quote a filename in an
+     application-specific fashion.  This is called if filename
+     completion is being attempted and one of the characters in
+     `rl_filename_quote_characters' appears in a completed filename.
+     The function is called with TEXT, MATCH_TYPE, and QUOTE_POINTER.
+     The TEXT is the filename to be quoted.  The MATCH_TYPE is either
+     `SINGLE_MATCH', if there is only one completion match, or
+     `MULT_MATCH'.  Some functions use this to decide whether or not to
+     insert a closing quote character.  The QUOTE_POINTER is a pointer
+     to any opening quote character the user typed.  Some functions
+     choose to reset this character.
+
+ -- Variable: rl_dequote_func_t * rl_filename_dequoting_function
+     A pointer to a function that will remove application-specific
+     quoting characters from a filename before completion is attempted,
+     so those characters do not interfere with matching the text
+     against names in the filesystem.  It is called with TEXT, the text
+     of the word to be dequoted, and QUOTE_CHAR, which is the quoting
+     character that delimits the filename (usually `'' or `"').  If
+     QUOTE_CHAR is zero, the filename was not in an embedded string.
+
+ -- Variable: rl_linebuf_func_t * rl_char_is_quoted_p
+     A pointer to a function to call that determines whether or not a
+     specific character in the line buffer is quoted, according to
+     whatever quoting mechanism the program calling Readline uses.  The
+     function is called with two arguments: TEXT, the text of the line,
+     and INDEX, the index of the character in the line.  It is used to
+     decide whether a character found in
+     `rl_completer_word_break_characters' should be used to break words
+     for the completer.
+
+ -- Variable: rl_compignore_func_t * rl_ignore_some_completions_function
+     This function, if defined, is called by the completer when real
+     filename completion is done, after all the matching names have
+     been generated.  It is passed a `NULL' terminated array of matches.
+     The first element (`matches[0]') is the maximal substring common
+     to all matches. This function can re-arrange the list of matches
+     as required, but each element deleted from the array must be freed.
+
+ -- Variable: rl_icppfunc_t * rl_directory_completion_hook
+     This function, if defined, is allowed to modify the directory
+     portion of filenames Readline completes.  It could be used to
+     expand symbolic links or shell variables in pathnames.  It is
+     called with the address of a string (the current directory name)
+     as an argument, and may modify that string.  If the string is
+     replaced with a new string, the old value should be freed.  Any
+     modified directory name should have a trailing slash.  The
+     modified value will be used as part of the completion, replacing
+     the directory portion of the pathname the user typed.  At the
+     least, even if no other expansion is performed, this function
+     should remove any quote characters from the directory name,
+     because its result will be passed directly to `opendir()'.  The
+     directory completion hook returns an integer that should be
+     non-zero if the function modifies its directory argument.  The
+     function should not modify the directory argument if it returns 0.
+
+ -- Variable: rl_dequote_func_t * rl_filename_rewrite_hook
+     If non-zero, this is the address of a function called when reading
+     directory entries from the filesystem for completion and comparing
+     them to the partial word to be completed.  The function should
+     perform any necesary application or system-specific conversion on
+     the filename, such as converting between character sets or
+     converting from a filesystem format to a character input format.
+     The function takes two arguments: FNAME, the filename to be
+     converted, and FNLEN, its length in bytes.  It must either return
+     its first argument (if no conversion takes place) or the converted
+     filename in newly-allocated memory.  The converted form is used to
+     compare against the word to be completed, and, if it matches, is
+     added to the list of matches.  Readline will free the allocated
+     string.
+
+ -- Variable: rl_compdisp_func_t * rl_completion_display_matches_hook
+     If non-zero, then this is the address of a function to call when
+     completing a word would normally display the list of possible
+     matches.  This function is called in lieu of Readline displaying
+     the list.  It takes three arguments: (`char **'MATCHES, `int'
+     NUM_MATCHES, `int' MAX_LENGTH) where MATCHES is the array of
+     matching strings, NUM_MATCHES is the number of strings in that
+     array, and MAX_LENGTH is the length of the longest string in that
+     array.  Readline provides a convenience function,
+     `rl_display_match_list', that takes care of doing the display to
+     Readline's output stream.  That function may be called from this
+     hook.
+
+ -- Variable: const char * rl_basic_word_break_characters
+     The basic list of characters that signal a break between words for
+     the completer routine.  The default value of this variable is the
+     characters which break words for completion in Bash: `"
+     \t\n\"\\'`@$><=;|&{("'.
+
+ -- Variable: const char * rl_basic_quote_characters
+     A list of quote characters which can cause a word break.
+
+ -- Variable: const char * rl_completer_word_break_characters
+     The list of characters that signal a break between words for
+     `rl_complete_internal()'.  The default list is the value of
+     `rl_basic_word_break_characters'.
+
+ -- Variable: rl_cpvfunc_t * rl_completion_word_break_hook
+     If non-zero, this is the address of a function to call when
+     Readline is deciding where to separate words for word completion.
+     It should return a character string like
+     `rl_completer_word_break_characters' to be used to perform the
+     current completion.  The function may choose to set
+     `rl_completer_word_break_characters' itself.  If the function
+     returns `NULL', `rl_completer_word_break_characters' is used.
+
+ -- Variable: const char * rl_completer_quote_characters
+     A list of characters which can be used to quote a substring of the
+     line.  Completion occurs on the entire substring, and within the
+     substring `rl_completer_word_break_characters' are treated as any
+     other character, unless they also appear within this list.
+
+ -- Variable: const char * rl_filename_quote_characters
+     A list of characters that cause a filename to be quoted by the
+     completer when they appear in a completed filename.  The default
+     is the null string.
+
+ -- Variable: const char * rl_special_prefixes
+     The list of characters that are word break characters, but should
+     be left in TEXT when it is passed to the completion function.
+     Programs can use this to help determine what kind of completing to
+     do.  For instance, Bash sets this variable to "$@" so that it can
+     complete shell variables and hostnames.
+
+ -- Variable: int rl_completion_query_items
+     Up to this many items will be displayed in response to a
+     possible-completions call.  After that, readline asks the user if
+     she is sure she wants to see them all.  The default value is 100.
+     A negative value indicates that Readline should never ask the user.
+
+ -- Variable: int rl_completion_append_character
+     When a single completion alternative matches at the end of the
+     command line, this character is appended to the inserted
+     completion text.  The default is a space character (` ').  Setting
+     this to the null character (`\0') prevents anything being appended
+     automatically.  This can be changed in application-specific
+     completion functions to provide the "most sensible word separator
+     character" according to an application-specific command line
+     syntax specification.
+
+ -- Variable: int rl_completion_suppress_append
+     If non-zero, RL_COMPLETION_APPEND_CHARACTER is not appended to
+     matches at the end of the command line, as described above.  It is
+     set to 0 before any application-specific completion function is
+     called, and may only be changed within such a function.
+
+ -- Variable: int rl_completion_quote_character
+     When Readline is completing quoted text, as delimited by one of the
+     characters in RL_COMPLETER_QUOTE_CHARACTERS, it sets this variable
+     to the quoting character found.  This is set before any
+     application-specific completion function is called.
+
+ -- Variable: int rl_completion_suppress_quote
+     If non-zero, Readline does not append a matching quote character
+     when performing completion on a quoted string.  It is set to 0
+     before any application-specific completion function is called, and
+     may only be changed within such a function.
+
+ -- Variable: int rl_completion_found_quote
+     When Readline is completing quoted text, it sets this variable to
+     a non-zero value if the word being completed contains or is
+     delimited by any quoting characters, including backslashes.  This
+     is set before any application-specific completion function is
+     called.
+
+ -- Variable: int rl_completion_mark_symlink_dirs
+     If non-zero, a slash will be appended to completed filenames that
+     are symbolic links to directory names, subject to the value of the
+     user-settable MARK-DIRECTORIES variable.  This variable exists so
+     that application-specific completion functions can override the
+     user's global preference (set via the MARK-SYMLINKED-DIRECTORIES
+     Readline variable) if appropriate.  This variable is set to the
+     user's preference before any application-specific completion
+     function is called, so unless that function modifies the value,
+     the user's preferences are honored.
+
+ -- Variable: int rl_ignore_completion_duplicates
+     If non-zero, then duplicates in the matches are removed.  The
+     default is 1.
+
+ -- Variable: int rl_filename_completion_desired
+     Non-zero means that the results of the matches are to be treated as
+     filenames.  This is _always_ zero when completion is attempted,
+     and can only be changed within an application-specific completion
+     function.  If it is set to a non-zero value by such a function,
+     directory names have a slash appended and Readline attempts to
+     quote completed filenames if they contain any characters in
+     `rl_filename_quote_characters' and `rl_filename_quoting_desired'
+     is set to a non-zero value.
+
+ -- Variable: int rl_filename_quoting_desired
+     Non-zero means that the results of the matches are to be quoted
+     using double quotes (or an application-specific quoting mechanism)
+     if the completed filename contains any characters in
+     `rl_filename_quote_chars'.  This is _always_ non-zero when
+     completion is attempted, and can only be changed within an
+     application-specific completion function.  The quoting is effected
+     via a call to the function pointed to by
+     `rl_filename_quoting_function'.
+
+ -- Variable: int rl_attempted_completion_over
+     If an application-specific completion function assigned to
+     `rl_attempted_completion_function' sets this variable to a non-zero
+     value, Readline will not perform its default filename completion
+     even if the application's completion function returns no matches.
+     It should be set only by an application's completion function.
+
+ -- Variable: int rl_sort_completion_matches
+     If an application sets this variable to 0, Readline will not sort
+     the list of completions (which implies that it cannot remove any
+     duplicate completions).  The default value is 1, which means that
+     Readline will sort the completions and, depending on the value of
+     `rl_ignore_completion_duplicates', will attempt to remove duplicate
+     matches.
+
+ -- Variable: int rl_completion_type
+     Set to a character describing the type of completion Readline is
+     currently attempting; see the description of
+     `rl_complete_internal()' (*note Completion Functions::) for the
+     list of characters.  This is set to the appropriate value before
+     any application-specific completion function is called, allowing
+     such functions to present the same interface as `rl_complete()'.
+
+ -- Variable: int rl_completion_invoking_key
+     Set to the final character in the key sequence that invoked one of
+     the completion functions that call `rl_complete_internal()'.  This
+     is set to the appropriate value before any application-specific
+     completion function is called.
+
+ -- Variable: int rl_inhibit_completion
+     If this variable is non-zero, completion is inhibited.  The
+     completion character will be inserted as any other bound to
+     `self-insert'.

+*****************************************
+
+                     Version 1.3, 3 November 2008
+
+     Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+     `http://fsf.org/'
+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.
+     We recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it
+     can be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You
+     accept the license if you copy, modify or distribute the work in a
+     way requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in
+     the notice that says that the Document is released under this
+     License.  If a section does not fit the above definition of
+     Secondary then it is not allowed to be designated as Invariant.
+     The Document may contain zero Invariant Sections.  If the Document
+     does not identify any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images
+     composed of pixels) generic paint programs or (for drawings) some
+     widely available drawing editor, and that is suitable for input to
+     text formatters or for automatic translation to a variety of
+     formats suitable for input to text formatters.  A copy made in an
+     otherwise Transparent file format whose markup, or absence of
+     markup, has been arranged to thwart or discourage subsequent
+     modification by readers is not Transparent.  An image format is
+     not Transparent if used for any substantial amount of text.  A
+     copy that is not "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and
+     standard-conforming simple HTML, PostScript or PDF designed for
+     human modification.  Examples of transparent image formats include
+     PNG, XCF and JPG.  Opaque formats include proprietary formats that
+     can be read and edited only by proprietary word processors, SGML or
+     XML for which the DTD and/or processing tools are not generally
+     available, and the machine-generated HTML, PostScript or PDF
+     produced by some word processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow
+     the conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the
+     title equally prominent and visible.  You may add other material
+     on the covers in addition.  Copying with changes limited to the
+     covers, as long as they preserve the title of the Document and
+     satisfy these conditions, can be treated as verbatim copying in
+     other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a
+     machine-readable Transparent copy along with each Opaque copy, or
+     state in or with each Opaque copy a computer-network location from
+     which the general network-using public has access to download
+     using public-standard network protocols a complete Transparent
+     copy of the Document, free of added material.  If you use the
+     latter option, you must take reasonably prudent steps, when you
+     begin distribution of Opaque copies in quantity, to ensure that
+     this Transparent copy will remain thus accessible at the stated
+     location until at least one year after the last time you
+     distribute an Opaque copy (directly or through your agents or
+     retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of
+     copies, to give them a chance to provide you with an updated
+     version of the Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with
+     the Modified Version filling the role of the Document, thus
+     licensing distribution and modification of the Modified Version to
+     whoever possesses a copy of it.  In addition, you must do these
+     things in the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of
+          previous versions (which should, if there were any, be listed
+          in the History section of the Document).  You may use the
+          same title as a previous version if the original publisher of
+          that version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on
+          the Title Page.  If there is no section Entitled "History" in
+          the Document, create one stating the title, year, authors,
+          and publisher of the Document as given on its Title Page,
+          then add an item describing the Modified Version as stated in
+          the previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in
+          the "History" section.  You may omit a network location for a
+          work that was published at least four years before the
+          Document itself, or if the original publisher of the version
+          it refers to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the
+          section all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document,
+          unaltered in their text and in their titles.  Section numbers
+          or the equivalent are not considered part of the section
+          titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option
+     designate some or all of these sections as invariant.  To do this,
+     add their titles to the list of Invariant Sections in the Modified
+     Version's license notice.  These titles must be distinct from any
+     other section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end
+     of the list of Cover Texts in the Modified Version.  Only one
+     passage of Front-Cover Text and one of Back-Cover Text may be
+     added by (or through arrangements made by) any one entity.  If the
+     Document already includes a cover text for the same cover,
+     previously added by you or by arrangement made by the same entity
+     you are acting on behalf of, you may not add another; but you may
+     replace the old one, on explicit permission from the previous
+     publisher that added the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination
+     all of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the
+     documents in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow
+     this License in all other respects regarding verbatim copying of
+     that document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of
+     a storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly
+     and finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from
+     you under this License.  If your rights have been terminated and
+     not permanently reinstated, receipt of a copy of some or all of
+     the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     `http://www.gnu.org/copyleft/'.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If
+     the Document does not specify a version number of this License,
+     you may choose any version ever published (not as a draft) by the
+     Free Software Foundation.  If the Document specifies that a proxy
+     can decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the @sc{gnu} Readline Library and
+other programs.  If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.

+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+@code{gets()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{EOF} while reading the line, and the
+line is empty at that point, then @code{(char *)NULL} is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+If you want the user to be able to get at the line later, (with
+@key{C-p} for example), you must call @code{add_history()} to save the
+line away in a @dfn{history} list of such lines.
+
+@example
+@code{add_history (line)};
+@end example
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    @{
+      free (line_read);
+      line_read = (char *)NULL;
+    @}
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read && *line_read)
+    add_history (line_read);
+
+  return (line_read);
+@}
+@end example
+
+This function gives the user the default behaviour of @key{TAB}
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the @key{TAB} key
+with @code{rl_bind_key()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features.  Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}.  @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}.

+@end menu
+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);
+
+@item typedef char *rl_quote_func_t (char *, int, char *);
+
+@item typedef char *rl_dequote_func_t (char *, int);
+
+@item typedef int rl_compignore_func_t (char **);
+
+@item typedef void rl_compdisp_func_t (char **, int, int);
+
+@item typedef int rl_hook_func_t (void);
+
+@item typedef int rl_getc_func_t (FILE *);
+
+@item typedef int rl_linebuf_func_t (char *, int);
+
+@item typedef int rl_intfunc_t (int);
+@item #define rl_ivoidfunc_t rl_hook_func_t
+@item typedef int rl_icpfunc_t (char *);

+@end table
+
+@node Function Writing
+@subsection Writing a New Function
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far.  You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.  The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}.  When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line.  If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read.  This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise.  Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line.  The cursor is moved to
+the beginning of the newly-blank line.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to
+@code{readline()}, and should not be assigned to directly.
+The @code{rl_set_prompt()} function (@pxref{Redisplay}) may
+be used to modify the prompt string after calling @code{readline()}.
+@end deftypevar
+
+@deftypevar {char *} rl_display_prompt
+The string displayed as the prompt.  This is usually identical to
+@var{rl_prompt}, but may be changed temporarily by functions that
+use the prompt string as a message area, such as incremental search.
+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.
+The calling application is responsible for managing the value; Readline
+never sets it.
+@end deftypevar
+
+@deftypevar {const char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar int rl_readline_version
+An integer encoding the current version of the library.  The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.
+For example, for Readline-4.2, @code{rl_readline_version} would have the
+value 0x0402.
+@end deftypevar
+
+@deftypevar {int} rl_gnu_readline_p
+Always set to 1, denoting that this is @sc{gnu} readline rather than some
+emulation.
+@end deftypevar
+
+@deftypevar {const char *} rl_terminal_name
+The terminal type, used for initialization.  If not set by the application,
+Readline sets this to the value of the @env{TERM} environment variable
+the first time it is called.
+@end deftypevar
+
+@deftypevar {const char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+If @code{NULL}, Readline defaults to @var{stdin}.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar int rl_prefer_env_winsize
+If non-zero, Readline gives values found in the @env{LINES} and
+@env{COLUMNS} environment variables greater precedence than values fetched
+from the kernel when computing the screen dimensions.
+@end deftypevar
+
+@deftypevar {rl_command_func_t *} rl_last_func
+The address of the last command function Readline executed.  May be used to
+test whether or not a function is being executed twice in succession, for
+example.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_pre_input_hook
+If non-zero, this is the address of a function to call after
+the first prompt has been printed and just before @code{readline}
+starts reading input characters.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when Readline is waiting for terminal input.
+By default, this will be called at most ten times a second if there
+is no keyboard input.
+@end deftypevar
+
+@deftypevar {rl_getc_func_t *} rl_getc_function
+If non-zero, Readline will call indirectly through this pointer
+to get a character from the input stream.  By default, it is set to
+@code{rl_getc}, the default Readline character input function
+(@pxref{Character Input}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_redisplay_function
+If non-zero, Readline will call indirectly through this pointer
+to update the display with the current contents of the editing buffer.
+By default, it is set to @code{rl_redisplay}, the default Readline
+redisplay function (@pxref{Redisplay}).
+@end deftypevar
+
+@deftypevar {rl_vintfunc_t *} rl_prep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to initialize the terminal.  The function takes a single argument, an
+@code{int} flag that says whether or not to use eight-bit characters.
+By default, this is set to @code{rl_prep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_deprep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to reset the terminal.  This function should undo the effects of
+@code{rl_prep_term_function}.
+By default, this is set to @code{rl_deprep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {Keymap} rl_executing_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+currently executing readline function was found.
+@end deftypevar 
+
+@deftypevar {Keymap} rl_binding_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+last key binding occurred.
+@end deftypevar 
+
+@deftypevar {char *} rl_executing_macro
+This variable is set to the text of any currently-executing macro.
+@end deftypevar
+
+@deftypevar {int} rl_readline_state
+A variable with bit values that encapsulate the current Readline state.
+A bit is set with the @code{RL_SETSTATE} macro, and unset with the
+@code{RL_UNSETSTATE} macro.  Use the @code{RL_ISSTATE} macro to test
+whether a particular state bit is set.  Current state bits include:

+
+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+@example
+Meta-Rubout:	backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+Add @var{name} to the list of named functions.  Make @var{function} be
+the function that gets called.  If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}.  The keymap is the
+association between the keys that the user types and the functions that
+get run.  You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap (void)

+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.

+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+Begins saving undo information in a group construct.  The undo
+information usually comes from calls to @code{rl_insert_text()} and
+@code{rl_delete_text()}, but could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}.  There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}).  The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list.  Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying()}
+once, just before you modify the text.  You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a
+single undo unit.  It is assumed that you will subsequently modify
+that text.

+@node Alternate Interface
+@subsection Alternate Interface
+
+An alternate interface is available to plain @code{readline()}.  Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to @code{select()}
+on various file descriptors.  To accomodate this need, readline can
+also be invoked as a `callback' function from an event loop.  There
+are functions available to make this easy.
+
+@deftypefun void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler)
+Set up the terminal for readline I/O and display the initial
+expanded value of @var{prompt}.  Save the value of @var{lhandler} to
+use as a function to call when a complete line of input has been entered.
+The function takes the text of the line as an argument.
+@end deftypefun
+
+@deftypefun void rl_callback_read_char (void)
+Whenever an application determines that keyboard input is available, it
+should call @code{rl_callback_read_char()}, which will read the next
+character from the current input source.
+If that character completes the line, @code{rl_callback_read_char} will
+invoke the @var{lhandler} function saved by @code{rl_callback_handler_install}
+to process the line.
+Before calling the @var{lhandler} function, the terminal settings are
+reset to the values they had before calling
+@code{rl_callback_handler_install}.
+If the @var{lhandler} function returns,
+the terminal settings are modified for Readline's use again.
+@code{EOF} is  indicated by calling @var{lhandler} with a
+@code{NULL} line.
+@end deftypefun
+
+@deftypefun void rl_callback_handler_remove (void)
+Restore the terminal to its initial state and remove the line handler.
+This may be called from within a callback as well as independently.
+If the @var{lhandler} installed by @code{rl_callback_handler_install}
+does not exit the program, either this function or the function referred

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state. 
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar
+
+@deftypevar int rl_catch_sigwinch
+If this variable is non-zero, Readline will install a signal handler for
+@code{SIGWINCH}.
+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar
+
+If an application does not wish to have Readline catch any signals, or
+to handle signals other than those Readline catches (@code{SIGHUP},
+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun void rl_cleanup_after_signal (void)
+This function will reset the state of the terminal to what it was before
+@code{readline()} was called, and remove the Readline signal handlers for
+all signals, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+@deftypefun void rl_free_line_state (void)
+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered
+keyboard macro, and any partially-entered numeric argument).  This
+should be called before @code{rl_cleanup_after_signal()}.  The
+Readline signal handler for @code{SIGINT} calls this to abort the
+current input line.
+@end deftypefun
+
+@deftypefun void rl_reset_after_signal (void)
+This will reinitialize the terminal and reinstall any Readline signal
+handlers, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+If an application does not wish Readline to catch @code{SIGWINCH}, it may
+call @code{rl_resize_terminal()} or @code{rl_set_screen_size()} to force
+Readline to update its idea of the terminal size when a @code{SIGWINCH}
+is received.
+
+@deftypefun void rl_echo_signal_char (int sig)
+If an application wishes to install its own signal handlers, but still
+have readline display characters that generate signals, calling this
+function with @var{sig} set to @code{SIGINT}, @code{SIGQUIT}, or
+@code{SIGTSTP} will display the character generating that signal.
+@end deftypefun

+@deftypefun void rl_resize_terminal (void)
+Update Readline's internal screen size by reading values from the kernel.
+@end deftypefun
+

+Set Readline's idea of the terminal size to @var{rows} rows and
+@var{cols} columns.  If either @var{rows} or @var{columns} is less than
+or equal to 0, Readline's idea of that terminal dimension is unchanged.
+@end deftypefun
+
+If an application does not want to install a @code{SIGWINCH} handler, but
+is still interested in the screen dimensions, Readline's idea of the screen
+size may be queried.
+
+@deftypefun void rl_get_screen_size (int *rows, int *cols)
+Return Readline's idea of the terminal's size in the

+
+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}.  This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time.  The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed.  @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+@dfn{application-specific completion function}.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()}).  The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.
+An @dfn{application-specific completion function} is a function whose
+address is assigned to @code{rl_completion_entry_function} and whose
+return values are used to  generate possible completions.
+@end deftypevar
+
+@node Completion Functions
+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point.  @var{what_to_do} says what to do
+with the completion.  A value of @samp{?} means list the possible
+completions.  @samp{TAB} means do standard completion.  @samp{*} means
+insert all of the possible completions.  @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.  @samp{@@} is similar to @samp{!}, but
+possible completions are not listed if the possible completions share
+a common prefix.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion.  This calls @code{rl_complete_internal()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key)
+List the possible completions.  See description of @code{rl_complete
+()}.  This calls @code{rl_complete_internal()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key)
+Insert the list of possible completions into the line, deleting the
+partially-completed word.  See description of @code{rl_complete()}.
+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the apppriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the values of the @code{show-all-if-ambiguous} and
+@code{show-all-if-unmodified} variables.
+Application-specific completion functions may use this function to present
+the same interface as @code{rl_complete()}.
+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for
+@var{text}.  If there are no completions, returns @code{NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions.  The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{char *}.  The first argument is @var{text}.  The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing application-specific
+completion functions (the Bash completion functions call this and other
+Readline functions).
+@end deftypefun
+
+@deftypefun {char *} rl_username_completion_function (const char *text, int state)
+A completion generator for usernames.  @var{text} contains a partial
+username preceded by a random character (usually @samp{~}).  As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()},
+the default filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion.  This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename.  The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
+is the filename to be quoted.  The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}.  Some functions use this to decide whether or not to
+insert a closing quote character.  The @var{quote_pointer} is a pointer
+to any opening quote character the user typed.  Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem.  It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}).  If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses.  The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line.  It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.
+It could be used to expand symbolic links or shell variables in pathnames.
+It is called with the address of a string (the current directory name) as an
+argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be used as part of the completion, replacing
+the directory portion of the pathname the user typed.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+The directory completion hook returns an integer that should be non-zero if
+the function modifies its directory argument.
+The function should not modify the directory argument if it returns 0.
+@end deftypevar
+
+@ignore
+@deftypevar extern rl_icppfunc_t *rl_directory_rewrite_hook;
+If non-zero, this is the address of a function to call when completing
+a directory name.  This function takes the address of the directory name
+to be modified as an argument.  Unlike @code{rl_directory_completion_hook},
+it only modifies the directory name used in @code{opendir}, not what is
+displayed when the possible completions are printed or inserted.  It is
+called before rl_directory_completion_hook.
+
+I'm not happy with how this works yet, so it's undocumented.
+@end deftypevar
+@end ignore
+
+@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook
+If non-zero, this is the address of a function called when reading
+directory entries from the filesystem for completion and comparing
+them to the partial word to be completed.  The function should
+perform any necesary application or system-specific conversion on
+the filename, such as converting between character sets or converting
+from a filesystem format to a character input format.
+The function takes two arguments: @var{fname}, the filename to be converted,
+and @var{fnlen}, its length in bytes.
+It must either return its first argument (if no conversion takes place)
+or the converted filename in newly-allocated memory.  The converted
+form is used to compare against the word to be completed, and, if it
+matches, is added to the list of matches.  Readline will free the
+allocated string.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.  That
+function may be called from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters

+If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion.  It should return
+a character string like @code{rl_completer_word_break_characters} to be
+used to perform the current completion.  The function may choose to set
+@code{rl_completer_word_break_characters} itself.  If the function
+returns @code{NULL}, @code{rl_completer_word_break_characters} is used.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename.  The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call.  After that, readline asks the user if she is sure
+she wants to see them all.  The default value is 100.  A negative value 
+indicates that Readline should never ask the user.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text.  The
+default is a space character (@samp{ }).  Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_quote_character
+When Readline is completing quoted text, as delimited by one of the
+characters in @var{rl_completer_quote_characters}, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_quote
+If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_found_quote
+When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames.  This is @emph{always} zero when completion is attempted,
+and can only be changed
+within an application-specific completion function.  If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in @code{rl_filename_quote_characters} and
+@code{rl_filename_quoting_desired} is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_sort_completion_matches
+If an application sets this variable to 0, Readline will not sort the
+list of completions (which implies that it cannot remove any duplicate
+completions).  The default value is 1, which means that Readline will
+sort the completions and, depending on the value of
+@code{rl_ignore_completion_duplicates}, will attempt to remove duplicate
+matches.
+@end deftypevar
+
+@deftypevar int rl_completion_type
+Set to a character describing the type of completion Readline is currently
+attempting; see the description of @code{rl_complete_internal()}
+(@pxref{Completion Functions}) for the list of characters.
+This is set to the appropriate value before any application-specific
+completion function is called, allowing such functions to present
+the same interface as @code{rl_complete()}.
+@end deftypevar
+
+@deftypevar int rl_completion_invoking_key
+Set to the final character in the key sequence that invoked one of the
+completion functions that call @code{rl_complete_internal()}.  This is
+set to the appropriate value before any application-specific completion
+function is called.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibited.  The completion
+character will be inserted as any other bound to @code{self-insert}.
+@end deftypevar

+@chapter Command Line Editing
+
+This chapter describes the basic features of the @sc{gnu}
+command line editing interface.
+@ifset BashFeatures
+Command line editing is provided by the Readline library, which is
+used by several different programs, including Bash.
+Command line editing is enabled by default when using an interactive shell,
+unless the @option{--noediting} option is supplied at shell invocation.
+Line editing is also used when using the @option{-e} option to the
+@code{read} builtin command (@pxref{Bash Builtins}).
+By default, the line editing commands are similar to those of Emacs.
+A vi-style line editing interface is also available.
+Line editing can be enabled at any time using the @option{-o emacs} or
+@option{-o vi} options to the @code{set} builtin command
+(@pxref{The Set Builtin}), or disabled using the @option{+o emacs} or 
+@option{+o vi} options to @code{set}.

+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @kbd{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @kbd{M-k} is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the @key{k}
+key is pressed.
+The Meta key is labeled @key{ALT} on many keyboards.
+On keyboards with two keys labeled @key{ALT} (usually to either side of
+the space bar), the @key{ALT} on the left side is generally set to
+work as a Meta key.
+The @key{ALT} key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+If you do not have a Meta or @key{ALT} key, or another key working as
+a Meta key, the identical keystroke can be generated by typing @key{ESC}
+@emph{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @kbd{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @kbd{C-k}.
+
+In addition, several keys have their own names.  Specifically,
+@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all
+stand for themselves when seen in this text, or in an init file
+(@pxref{Readline Init File}).
+If your keyboard lacks a @key{LFD} key, typing @key{C-j} will
+produce the desired character.
+The @key{RET} key may be labeled @key{Return} or @key{Enter} on
+some keyboards.
+
+@node Readline Interaction
+@section Readline Interaction
+@cindex interaction, readline
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press @key{RET}.  You do not have to be at the
+end of the line to press @key{RET}; the entire line is accepted
+regardless of the location of the cursor within the line.

+@node Readline Bare Essentials
+@subsection Readline Bare Essentials
+@cindex notation, readline
+@cindex command editing
+@cindex editing command lines
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type @kbd{C-b} to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with @kbd{C-f}.
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @kbd{C-b}
+Move back one character.
+@item @kbd{C-f}
+Move forward one character.
+@item @key{DEL} or @key{Backspace}
+Delete the character to the left of the cursor.
+@item @kbd{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @kbd{C-_} or @kbd{C-x C-u}
+Undo the last editing command.  You can undo all the way back to an
+empty line.
+@end table
+
+@noindent
+(Depending on your configuration, the @key{Backspace} key be set to
+delete the character to the left of the cursor and the @key{DEL} key set
+to delete the character underneath the cursor, like @kbd{C-d}, rather
+than the character to the left of the cursor.)
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to @kbd{C-b}, @kbd{C-f},
+@kbd{C-d}, and @key{DEL}.  Here are some commands for moving more rapidly
+about the line.
+
+@table @kbd
+@item C-a
+Move to the start of the line.
+@item C-e
+Move to the end of the line.
+@item M-f
+Move forward a word, where a word is composed of letters and digits.
+@item M-b
+Move backward a word.
+@item C-l
+Clear the screen, reprinting the current line at the top.
+@end table
+
+Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+@node Readline Killing Commands
+@subsection Readline Killing Commands
+
+@cindex killing text
+@cindex yanking text
+
+@dfn{Killing} text means to delete the text from the line, but to save
+it away for later use, usually by @dfn{yanking} (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+When you use a kill command, the text is saved in a @dfn{kill-ring}.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+@cindex kill ring
+
+Here is the list of commands for killing text.
+
+@table @kbd
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item M-d
+Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by @kbd{M-f}.
+
+@item M-@key{DEL}
+Kill from the cursor the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by @kbd{M-b}.
+
+@item C-w
+Kill from the cursor to the previous whitespace.  This is different than
+@kbd{M-@key{DEL}} because the word boundaries differ.
+
+@end table
+
+Here is how to @dfn{yank} the text back into the line.  Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+@table @kbd
+@item C-y
+Yank the most recently killed text back into the buffer at the cursor.
+
+@item M-y
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is @kbd{C-y} or @kbd{M-y}.
+@end table
+
+@node Readline Arguments
+@subsection Readline Arguments
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the @i{sign} of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type @samp{M-- C-k}.
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (@samp{-}), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d},
+which will delete the next ten characters on the input line.
+
+@node Searching
+@subsection Searching for Commands in the History
+
+Readline provides commands for searching through the command history
+@ifset BashFeatures
+(@pxref{Bash History Facilities})
+@end ifset
+for lines containing a specified string.
+There are two search modes:  @dfn{incremental} and @dfn{non-incremental}.
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+@kbd{C-r}.  Typing @kbd{C-s} searches forward through the history.
+The characters present in the value of the @code{isearch-terminators} variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the @key{ESC} and
+@kbd{C-J} characters will terminate an incremental search.
+@kbd{C-g} will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+To find other matching entries in the history list, type @kbd{C-r} or
+@kbd{C-s} as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a @key{RET} will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+Readline remembers the last incremental search string.  If two
+@kbd{C-r}s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+
+@node Readline Init File
+@section Readline Init File
+@cindex initialization file, readline
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an @dfn{inputrc} file, conventionally in his home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @env{INPUTRC}.  If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @env{INPUTRC}.  If
+@end ifclear
+that variable is unset, the default is @file{~/.inputrc}.  If that
+file does not exist or cannot be read, the ultimate default is
+@file{/etc/inputrc}.
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+In addition, the @code{C-x C-r} command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+

+@end menu
+
+@node Readline Init File Syntax
+@subsection Readline Init File Syntax
+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a @samp{#} are comments.
+Lines beginning with a @samp{$} indicate conditional
+constructs (@pxref{Conditional Init Constructs}).  Other lines
+denote variable settings and key bindings.
+
+@table @asis
+@item Variable Settings
+You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the @code{set} command within the init file.
+The syntax is simple:
+
+@example
+set @var{variable} @var{value}
+@end example
+
+@noindent
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+@code{vi} line editing commands:
+
+@example
+set editing-mode vi
+@end example
+
+Variable names and values, where appropriate, are recognized without regard
+to case.  Unrecognized variable names are ignored.
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, @var{on} (case-insensitive), or 1.  Any other
+value results in the variable being set to off.
+
+@ifset BashFeatures
+The @w{@code{bind -V}} command lists the current Readline variable names
+and values.  @xref{Bash Builtins}.
+@end ifset
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@cindex variables, readline
+@table @code
+
+@item bell-style
+@vindex bell-style
+Controls what happens when Readline wants to ring the terminal bell.
+If set to @samp{none}, Readline never rings the bell.  If set to
+@samp{visible}, Readline uses a visible bell if one is available.
+If set to @samp{audible} (the default), Readline attempts to ring
+the terminal's bell.
+
+@item bind-tty-special-chars
+@vindex bind-tty-special-chars
+If set to @samp{on}, Readline attempts to bind the control characters  
+treated specially by the kernel's terminal driver to their Readline
+equivalents.
+
+@item comment-begin
+@vindex comment-begin
+The string to insert at the beginning of the line when the
+@code{insert-comment} command is executed.  The default value
+is @code{"#"}.
+
+@item completion-display-width
+@vindex completion-display-width
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+
+@item completion-ignore-case
+@vindex completion-ignore-case
+If set to @samp{on}, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is @samp{off}.
+
+@item completion-map-case
+@vindex completion-map-case
+If set to @samp{on}, and @var{completion-ignore-case} is enabled, Readline
+treats hyphens (@samp{-}) and underscores (@samp{_}) as equivalent when
+performing case-insensitive filename matching and completion.
+
+@item completion-prefix-display-length
+@vindex completion-prefix-display-length
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+
+@item completion-query-items
+@vindex completion-query-items
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is @code{100}.
+
+@item convert-meta
+@vindex convert-meta
+If set to @samp{on}, Readline will convert characters with the
+eighth bit set to an @sc{ascii} key sequence by stripping the eighth
+bit and prefixing an @key{ESC} character, converting them to a
+meta-prefixed key sequence.  The default value is @samp{on}.
+
+@item disable-completion
+@vindex disable-completion
+If set to @samp{On}, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to @code{self-insert}.  The default is @samp{off}.
+
+@item editing-mode
+@vindex editing-mode
+The @code{editing-mode} variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either @samp{emacs} or @samp{vi}.
+
+@item echo-control-characters
+When set to @samp{on}, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.  The default is @samp{on}.
+
+@item enable-keypad
+@vindex enable-keypad
+When set to @samp{on}, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is @samp{off}.
+
+@item enable-meta-key
+When set to @samp{on}, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+The default is @samp{on}.
+
+@item expand-tilde
+@vindex expand-tilde
+If set to @samp{on}, tilde expansion is performed when Readline
+attempts word completion.  The default is @samp{off}.
+
+@item history-preserve-point
+@vindex history-preserve-point
+If set to @samp{on}, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with @code{previous-history}
+or @code{next-history}.  The default is @samp{off}.
+
+@item history-size
+@vindex history-size
+Set the maximum number of history entries saved in the history list.  If
+set to zero, the number of entries in the history list is not limited.
+
+@item horizontal-scroll-mode
+@vindex horizontal-scroll-mode
+This variable can be set to either @samp{on} or @samp{off}.  Setting it
+to @samp{on} means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to @samp{off}.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is @samp{off}.  The name @code{meta-flag} is a
+synonym for this variable.
+
+@item isearch-terminators
+@vindex isearch-terminators
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (@pxref{Searching}).
+If this variable has not been given a value, the characters @key{ESC} and
+@kbd{C-J} will terminate an incremental search.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-move},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command}; @code{emacs} is
+equivalent to @code{emacs-standard}.  The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended.  The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item mark-symlinked-directories
+@vindex mark-symlinked-directories
+If set to @samp{on}, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+@code{mark-directories}).
+The default is @samp{off}.
+
+@item match-hidden-files
+@vindex match-hidden-files
+This variable, when set to @samp{on}, causes Readline to match files whose
+names begin with a @samp{.} (hidden files) when performing filename
+completion.
+If set to @samp{off}, the leading @samp{.} must be
+supplied by the user in the filename to be completed.
+This variable is @samp{on} by default.
+
+@item menu-complete-display-prefix
+@vindex menu-complete-display-prefix
+If set to @samp{on}, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.  The default is @samp{off}.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is @samp{off}.
+
+@item page-completions
+@vindex page-completions
+If set to @samp{on}, Readline uses an internal @code{more}-like pager
+to display a screenful of possible completions at a time.
+This variable is @samp{on} by default.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item revert-all-at-newline
+@vindex revert-all-at-newline
+If set to @samp{on}, Readline will undo all changes to history lines
+before returning when @code{accept-line} is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to @code{readline}.  The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions.  If
+set to @samp{on}, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item show-all-if-unmodified
+@vindex show-all-if-unmodified
+This alters the default behavior of the completion functions in
+a fashion similar to @var{show-all-if-ambiguous}.
+If set to @samp{on}, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is @samp{off}.
+
+@item skip-completed-text
+@vindex skip-completed-text
+If set to @samp{on}, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the @samp{e} in @samp{Makefile} will result in @samp{Makefile}
+rather than @samp{Makefilefile}, assuming there is a single possible
+completion.
+The default value is @samp{off}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a @var{macro}).
+
+@ifset BashFeatures
+The @w{@code{bind -p}} command displays Readline function names and
+bindings in a format that can put directly into an initialization file.
+@xref{Bash Builtins}.
+@end ifset
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English.  For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the above example, @kbd{C-u} is bound to the function
+@code{universal-argument},
+@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and
+@kbd{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+@var{DEL},
+@var{ESC},
+@var{ESCAPE},
+@var{LFD},
+@var{NEWLINE},
+@var{RET},
+@var{RETURN},
+@var{RUBOUT},
+@var{SPACE},
+@var{SPC},
+and
+@var{TAB}.
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes.  Some @sc{gnu} Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+

+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+
+@table @code
+@item $if
+The @code{$if} construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}.  This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item application
+The @var{application} construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the @var{application name}, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+@end example
+@end table
+
+@item $endif
+This command, as seen in the previous example, terminates an
+@code{$if} command.
+
+@item $else
+Commands in this branch of the @code{$if} directive are executed if
+the test fails.
+
+@item $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from @file{/etc/inputrc}:
+@example
+$include /etc/inputrc
+@end example
+@end table
+
+@node Sample Init File
+@subsection Sample Init File

+Here is an example of an @var{inputrc} file.  This illustrates key
+binding, variable assignment, and conditional syntax.

+being entered.
+
+@item reverse-search-history (C-r)
+Search backward starting at the current line and moving `up' through
+the history as necessary.  This is an incremental search.
+
+@item forward-search-history (C-s)
+Search forward starting at the current line and moving `down' through

+the second word on the previous line) at point.
+With an argument @var{n},
+insert the @var{n}th word from the previous command (the words
+in the previous command begin with word 0).  A negative argument

+Once the argument @var{n} is computed, the argument is extracted
+as if the @samp{!@var{n}} history expansion had been specified.
+
+@item yank-last-arg (M-. or M-_)
+Insert last argument to the previous command (the last word of the
+previous history entry).
+With a numeric argument, behave exactly like @code{yank-nth-arg}.
+Successive calls to @code{yank-last-arg} move back through the history
+list, inserting the last word (or the word specified by the argument to
+the first call) of each line in turn.
+Any numeric argument supplied to these successive calls determines

+@node Commands For Text
+@subsection Commands For Changing Text
+
+@ftable @code
+@item delete-char (C-d)
+Delete the character at point.  If point is at the

+the last character typed was not bound to @code{delete-char}, then
+return @sc{eof}.
+
+@item backward-delete-char (Rubout)
+Delete the character behind the cursor.  A numeric argument means
+to kill the characters instead of deleting them.
+
+@item forward-backward-delete-char ()
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.  By default, this is not bound to a key.
+
+@item quoted-insert (C-q or C-v)
+Add the next character typed to the line verbatim.  This is
+how to insert key sequences like @kbd{C-q}, for example.
+
+@ifclear BashFeatures
+@item tab-insert (M-@key{TAB})
+Insert a tab character.
+@end ifclear
+
+@item self-insert (a, b, A, 1, !, @dots{})
+Insert yourself.
+
+@item transpose-chars (C-t)
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well.  If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+@item transpose-words (M-t)
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+@item upcase-word (M-u)
+Uppercase the current (or following) word.  With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+@item downcase-word (M-l)
+Lowercase the current (or following) word.  With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+@item capitalize-word (M-c)
+Capitalize the current (or following) word.  With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+@item overwrite-mode ()
+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+@code{emacs} mode; @code{vi} mode does overwrite differently.
+Each call to @code{readline()} starts in insert mode.
+
+In overwrite mode, characters bound to @code{self-insert} replace

+
+@item delete-horizontal-space ()
+Delete all spaces and tabs around point.  By default, this is unbound.
+
+@item kill-region ()
+Kill the text in the current region.
+By default, this command is unbound.

+
+@item universal-argument ()
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the

+@item possible-completions (M-?)
+List the possible completions of the text before point.

+for display to the value of @code{completion-display-width}, the value of
+the environment variable @env{COLUMNS}, or the screen width, in that order.
+
+@item insert-completions (M-*)
+Insert all completions of the text before point that would have
+been generated by @code{possible-completions}.
+
+@item menu-complete ()
+Similar to @code{complete}, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of @code{menu-complete} steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung
+(subject to the setting of @code{bell-style})
+and the original text is restored.
+An argument of @var{n} moves @var{n} positions forward in the list
+of matches; a negative argument may be used to move backward
+through the list.
+This command is intended to be bound to @key{TAB}, but is unbound

+@ifset BashFeatures
+@node Programmable Completion
+@section Programmable Completion
+@cindex programmable completion
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a @var{compspec}) has been defined
+using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
+the programmable completion facilities are invoked. 
+
+First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is the empty string (completion attempted at the
+beginning of an empty line), any compspec defined with
+the @option{-E} option to @code{complete} is used.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+If those searches do not result in a compspec, any compspec defined with
+the @option{-D} option to @code{complete} is used as the default.
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (@pxref{Commands For Completion}) is performed.
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the @option{-f} or @option{-d} option is used for filename or
+directory name completion, the shell variable @env{FIGNORE} is
+used to filter the matches.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+
+Any completions specified by a filename expansion pattern to the
+@option{-G} option are generated next.
+The words generated by the pattern need not match the word being completed.
+The @env{GLOBIGNORE} shell variable is not used to filter the matches,
+but the @env{FIGNORE} shell variable is used.
+
+Next, the string specified as the argument to the @option{-W} option
+is considered.
+The string is first split using the characters in the @env{IFS}
+special variable as delimiters.
+Shell quoting is honored.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above (@pxref{Shell Expansions}).
+The results are split using the rules described above
+(@pxref{Word Splitting}).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+
+After these matches have been generated, any shell function or command
+specified with the @option{-F} and @option{-C} options is invoked.
+When the command or function is invoked, the @env{COMP_LINE},
+@env{COMP_POINT}, @env{COMP_KEY}, and @env{COMP_TYPE} variables are
+assigned values as described above (@pxref{Bash Variables}).
+If a shell function is being invoked, the @env{COMP_WORDS} and
+@env{COMP_CWORD} variables are also set.
+When the function or command is invoked, the first argument is the
+name of the command whose arguments are being completed, the
+second argument is the word being completed, and the third argument
+is the word preceding the word being completed on the current command line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+Any function specified with @option{-F} is invoked first.
+The function may use any of the shell facilities, including the
+@code{compgen} and @code{compopt} builtins described below
+(@pxref{Programmable Completion Builtins}), to generate the matches.
+It must put the possible completions in the @env{COMPREPLY} array
+variable.
+
+Next, any command specified with the @option{-C} option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+
+After all of the possible completions are generated, any filter
+specified with the @option{-X} option is applied to the list.
+The filter is a pattern as used for pathname expansion; a @samp{&}
+in the pattern is replaced with the text of the word being completed.
+A literal @samp{&} may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading @samp{!} negates the pattern; in this case any completion
+not matching the pattern will be removed.
+
+Finally, any prefix and suffix specified with the @option{-P} and @option{-S}
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+
+If the previously-applied actions do not generate any matches, and the
+@option{-o dirnames} option was supplied to @code{complete} when the
+compspec was defined, directory name completion is attempted. 
+
+If the @option{-o plusdirs} option was supplied to @code{complete} when
+the compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the @option{-o bashdefault} option was supplied to @code{complete} when
+the compspec was defined, the default Bash completions are attempted
+if the compspec generates no matches.
+If the @option{-o default} option was supplied to @code{complete} when the
+compspec was defined, Readline's default completion will be performed
+if the compspec (and, if attempted, the default Bash completions)
+generate no matches.
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the @var{mark-directories} Readline variable, regardless
+of the setting of the @var{mark-symlinked-directories} Readline variable.
+
+There is some support for dynamically modifying completions.  This is
+most useful when used in combination with a default completion specified
+with @option{-D}.  It's possible for shell functions executed as completion
+handlers to indicate that completion should be retried by returning an
+exit status of 124.  If a shell function returns 124, and changes
+the compspec associated with the command on which completion is being
+attempted (supplied as the first argument when the function is executed),
+programmable completion restarts from the beginning, with an
+attempt to find a new compspec for that command.  This allows a set of
+completions to be built dynamically as completion is attempted, rather than
+being loaded all at once.
+
+For instance, assuming that there is a library of compspecs, each kept in a
+file corresponding to the name of the command, the following default
+completion function would load completions dynamically:
+
+@example
+_completion_loader()
+@{
+	. "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124
+@}
+complete -D -F _completion_loader
+@end example
+
+@node Programmable Completion Builtins

+Two builtin commands are available to manipulate the programmable completion
+facilities.
+
+@table @code
+@item compgen
+@btindex compgen
+@example
+@code{compgen [@var{option}] [@var{word}]}
+@end example
+
+Generate possible completion matches for @var{word} according to
+the @var{option}s, which may be any option accepted by the
+@code{complete}
+builtin with the exception of @option{-p} and @option{-r}, and write
+the matches to the standard output.
+When using the @option{-F} or @option{-C} options, the various shell variables
+set by the programmable completion facilities, while available, will not
+have useful values.
+
+The matches will be generated in the same way as if the programmable
+completion code had generated them directly from a completion specification
+with the same flags.
+If @var{word} is specified, only those completions matching @var{word}
+will be displayed.
+
+The return value is true unless an invalid option is supplied, or no
+matches were generated.

+@end example
+
+Specify how arguments to each @var{name} should be completed.
+If the @option{-p} option is supplied, or if no options are supplied, existing
+completion specifications are printed in a way that allows them to be
+reused as input.
+The @option{-r} option removes a completion specification for
+each @var{name}, or, if no @var{name}s are supplied, all
+completion specifications.
+The @option{-D} option indicates that the remaining options and actions should
+apply to the ``default'' command completion; that is, completion attempted
+on a command for which no completion has previously been defined.
+The @option{-E} option indicates that the remaining options and actions should
+apply to ``empty'' command completion; that is, completion attempted on a 
+blank line.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}).  The
+@option{-D} option takes precedence over @option{-E}.
+
+Other options, if specified, have the following meanings.
+The arguments to the @option{-G}, @option{-W}, and @option{-X} options
+(and, if necessary, the @option{-P} and @option{-S} options)
+should be quoted to protect them from expansion before the
+@code{complete} builtin is invoked.
+
+
+@table @code

+Perform directory name completion if the compspec generates no matches.
+
+@item filenames
+Tell Readline that the compspec generates filenames, so it can perform any
+filename-specific processing (like adding a slash to directory names
+quoting special characters, or suppressing trailing spaces).
+This option is intended to be used with shell functions specified
+with @option{-F}.
+
+@item nospace
+Tell Readline not to append a space (the default) to words completed at
+the end of the line.

+
+The following paragraphs describe the notation used to represent
+keystrokes.
+</P><P>
+
+The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
+produced when the <KBD>k</KBD> key is pressed while the Control key
+is depressed.
+</P><P>
+
+The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
+key is pressed.
+The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
+On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
+the space bar), the <KBD>ALT</KBD> on the left side is generally set to
+work as a Meta key.
+The <KBD>ALT</KBD> key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+</P><P>
+
+If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
+a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
+<EM>first</EM>, and then typing <KBD>k</KBD>.
+Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
+</P><P>
+
+The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
+character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
+</P><P>
+
+In addition, several keys have their own names.  Specifically,
+<KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
+stand for themselves when seen in this text, or in an init file
+(see section <A HREF="rluserman.html#SEC9">1.3 Readline Init File</A>).
+If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
+produce the desired character.
+The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
+some keyboards.

+<!--docid::SEC3::-->
+<P>
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
+end of the line to press <KBD>RET</KBD>; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+</P><P>
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with <KBD>C-f</KBD>.
+</P><P>
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the bare

+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
+<KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly

+<EM>Killing</EM> text means to delete the text from the line, but to save

+it back into the line.

+<!--docid::SEC7::-->
+<P>
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the <I>sign</I> of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
+</P><P>
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
+which will delete the next ten characters on the input line.

+<H3> 1.2.5 Searching for Commands in the History </H3>
+<!--docid::SEC8::-->
+<P>
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
+</P><P>
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+<KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
+The characters present in the value of the <CODE>isearch-terminators</CODE> variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the <KBD>ESC</KBD> and
+<KBD>C-J</KBD> characters will terminate an incremental search.
+<KBD>C-g</KBD> will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+</P><P>
+
+To find other matching entries in the history list, type <KBD>C-r</KBD> or
+<KBD>C-s</KBD> as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a <KBD>RET</KBD> will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+</P><P>
+
+Readline remembers the last incremental search string.  If two
+<KBD>C-r</KBD>s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+</P><P>
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+<H2> 1.3 Readline Init File </H2>
+<!--docid::SEC9::-->
+<P>
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an <EM>inputrc</EM> file, conventionally in his home directory.
+The name of this
+file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
+that variable is unset, the default is <TT>`~/.inputrc'</TT>.  If that
+file does not exist or cannot be read, the ultimate default is
+<TT>`/etc/inputrc'</TT>.
+</P><P>
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+</P><P>
+
+In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+<!--docid::SEC10::-->
+<P>
+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a <SAMP>`#'</SAMP> are comments.
+Lines beginning with a <SAMP>`$'</SAMP> indicate conditional
+constructs (see section <A HREF="rluserman.html#SEC11">1.3.2 Conditional Init Constructs</A>).  Other lines
+denote variable settings and key bindings.

+
+<DL COMPACT>
+<DT>Variable Settings
+<DD>You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the <CODE>set</CODE> command within the init file.
+The syntax is simple:
+<P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR>
+</pre></td></tr></table></P><P>
+
+Here, for example, is how to

+<CODE>vi</CODE> line editing commands:
+</P><P>
+
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>set editing-mode vi

+
+Variable names and values, where appropriate, are recognized without regard
+to case.  Unrecognized variable names are ignored.
+</P><P>
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, <VAR>on</VAR> (case-insensitive), or 1.  Any other
+value results in the variable being set to off.
+</P><P>
+
+A great deal of run-time behavior is changeable with the following
+variables.
+</P><P>
+
+<A NAME="IDX4"></A>
+<DL COMPACT>
+
+<DT><CODE>bell-style</CODE>
+<DD><A NAME="IDX5"></A>
+Controls what happens when Readline wants to ring the terminal bell.
+If set to <SAMP>`none'</SAMP>, Readline never rings the bell.  If set to
+<SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available.
+If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring
+the terminal's bell.
+<P>
+
+<DT><CODE>bind-tty-special-chars</CODE>
+<DD><A NAME="IDX6"></A>
+If set to <SAMP>`on'</SAMP>, Readline attempts to bind the control characters  
+treated specially by the kernel's terminal driver to their Readline
+equivalents.
+<P>
+
+<DT><CODE>comment-begin</CODE>
+<DD><A NAME="IDX7"></A>
+The string to insert at the beginning of the line when the
+<CODE>insert-comment</CODE> command is executed.  The default value
+is <CODE>"#"</CODE>.
+<P>
+
+<DT><CODE>completion-display-width</CODE>
+<DD><A NAME="IDX8"></A>
+The number of screen columns used to display possible matches
+when performing completion.
+The value is ignored if it is less than 0 or greater than the terminal
+screen width.
+A value of 0 will cause matches to be displayed one per line.
+The default value is -1.
+<P>
+
+<DT><CODE>completion-ignore-case</CODE>
+<DD><A NAME="IDX9"></A>
+If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>completion-map-case</CODE>
+<DD><A NAME="IDX10"></A>
+If set to <SAMP>`on'</SAMP>, and <VAR>completion-ignore-case</VAR> is enabled, Readline
+treats hyphens (<SAMP>`-'</SAMP>) and underscores (<SAMP>`_'</SAMP>) as equivalent when
+performing case-insensitive filename matching and completion.
+<P>
+
+<DT><CODE>completion-prefix-display-length</CODE>
+<DD><A NAME="IDX11"></A>
+The length in characters of the common prefix of a list of possible
+completions that is displayed without modification.  When set to a
+value greater than zero, common prefixes longer than this value are
+replaced with an ellipsis when displaying possible completions.
+<P>
+
+<DT><CODE>completion-query-items</CODE>
+<DD><A NAME="IDX12"></A>
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is <CODE>100</CODE>.
+<P>
+
+<DT><CODE>convert-meta</CODE>
+<DD><A NAME="IDX13"></A>
+If set to <SAMP>`on'</SAMP>, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prefixing an <KBD>ESC</KBD> character, converting them to a
+meta-prefixed key sequence.  The default value is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>disable-completion</CODE>
+<DD><A NAME="IDX14"></A>
+If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to <CODE>self-insert</CODE>.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>editing-mode</CODE>
+<DD><A NAME="IDX15"></A>
+The <CODE>editing-mode</CODE> variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>.
+<P>
+
+<DT><CODE>echo-control-characters</CODE>
+<DD>When set to <SAMP>`on'</SAMP>, on operating systems that indicate they support it,
+readline echoes a character corresponding to a signal generated from the
+keyboard.  The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>enable-keypad</CODE>
+<DD><A NAME="IDX16"></A>
+When set to <SAMP>`on'</SAMP>, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>enable-meta-key</CODE>
+<DD>When set to <SAMP>`on'</SAMP>, Readline will try to enable any meta modifier
+key the terminal claims to support when it is called.  On many terminals,
+the meta key is used to send eight-bit characters.
+The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>expand-tilde</CODE>
+<DD><A NAME="IDX17"></A>
+If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline
+attempts word completion.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>history-preserve-point</CODE>
+<DD><A NAME="IDX18"></A>
+If set to <SAMP>`on'</SAMP>, the history code attempts to place the point (the
+current cursor position) at the
+same location on each history line retrieved with <CODE>previous-history</CODE>
+or <CODE>next-history</CODE>.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>history-size</CODE>
+<DD><A NAME="IDX19"></A>
+Set the maximum number of history entries saved in the history list.  If
+set to zero, the number of entries in the history list is not limited.
+<P>
+
+<DT><CODE>horizontal-scroll-mode</CODE>
+<DD><A NAME="IDX20"></A>
+This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
+to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>input-meta</CODE>
+<DD><A NAME="IDX21"></A>
+<A NAME="IDX22"></A>
+If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is <SAMP>`off'</SAMP>.  The name <CODE>meta-flag</CODE> is a
+synonym for this variable.
+<P>
+
+<DT><CODE>isearch-terminators</CODE>
+<DD><A NAME="IDX23"></A>
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">1.2.5 Searching for Commands in the History</A>).
+If this variable has not been given a value, the characters <KBD>ESC</KBD> and
+<KBD>C-J</KBD> will terminate an incremental search.
+<P>
+
+<DT><CODE>keymap</CODE>
+<DD><A NAME="IDX24"></A>
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable <CODE>keymap</CODE> names are
+<CODE>emacs</CODE>,
+<CODE>emacs-standard</CODE>,
+<CODE>emacs-meta</CODE>,
+<CODE>emacs-ctlx</CODE>,
+<CODE>vi</CODE>,
+<CODE>vi-move</CODE>,
+<CODE>vi-command</CODE>, and
+<CODE>vi-insert</CODE>.
+<CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
+equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.
+The value of the <CODE>editing-mode</CODE> variable also affects the
+default keymap.
+<P>
+
+<DT><CODE>mark-directories</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash
+appended.  The default is <SAMP>`on'</SAMP>.
+<P>
+
+<DT><CODE>mark-modified-lines</CODE>
+<DD><A NAME="IDX25"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an
+asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified.
+This variable is <SAMP>`off'</SAMP> by default.
+<P>
+
+<DT><CODE>mark-symlinked-directories</CODE>
+<DD><A NAME="IDX26"></A>
+If set to <SAMP>`on'</SAMP>, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+<CODE>mark-directories</CODE>).
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>match-hidden-files</CODE>
+<DD><A NAME="IDX27"></A>
+This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
+names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
+completion.
+If set to <SAMP>`off'</SAMP>, the leading <SAMP>`.'</SAMP> must be
+supplied by the user in the filename to be completed.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>menu-complete-display-prefix</CODE>
+<DD><A NAME="IDX28"></A>
+If set to <SAMP>`on'</SAMP>, menu completion displays the common prefix of the
+list of possible completions (which may be empty) before cycling through
+the list.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>output-meta</CODE>
+<DD><A NAME="IDX29"></A>
+If set to <SAMP>`on'</SAMP>, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>page-completions</CODE>
+<DD><A NAME="IDX30"></A>
+If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
+to display a screenful of possible completions at a time.
+This variable is <SAMP>`on'</SAMP> by default.
+<P>
+
+<DT><CODE>print-completions-horizontally</CODE>
+<DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>revert-all-at-newline</CODE>
+<DD><A NAME="IDX31"></A>
+If set to <SAMP>`on'</SAMP>, Readline will undo all changes to history lines
+before returning when <CODE>accept-line</CODE> is executed.  By default,
+history lines may be modified and retain individual undo lists across
+calls to <CODE>readline</CODE>.  The default is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>show-all-if-ambiguous</CODE>
+<DD><A NAME="IDX32"></A>
+This alters the default behavior of the completion functions.  If
+set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>show-all-if-unmodified</CODE>
+<DD><A NAME="IDX33"></A>
+This alters the default behavior of the completion functions in
+a fashion similar to <VAR>show-all-if-ambiguous</VAR>.
+If set to <SAMP>`on'</SAMP>, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>skip-completed-text</CODE>
+<DD><A NAME="IDX34"></A>
+If set to <SAMP>`on'</SAMP>, this alters the default completion behavior when
+inserting a single match into the line.  It's only active when
+performing completion in the middle of a word.  If enabled, readline
+does not insert characters from the completion that match characters
+after point in the word being completed, so portions of the word
+following the cursor are not duplicated.
+For instance, if this is enabled, attempting completion when the cursor
+is after the <SAMP>`e'</SAMP> in <SAMP>`Makefile'</SAMP> will result in <SAMP>`Makefile'</SAMP>
+rather than <SAMP>`Makefilefile'</SAMP>, assuming there is a single possible
+completion.
+The default value is <SAMP>`off'</SAMP>.
+<P>
+
+<DT><CODE>visible-stats</CODE>
+<DD><A NAME="IDX35"></A>
+If set to <SAMP>`on'</SAMP>, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is <SAMP>`off'</SAMP>.
+<P>

+</DL>
+<P>
+
+<DT>Key Bindings
+<DD>The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+<P>
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.
+There can be no space between the key name and the colon -- that will be
+interpreted as part of the key name.
+The name of the key can be expressed in different ways, depending on
+what you find most comfortable.

+
+<DL COMPACT>
+<DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>

+<H3> 1.3.2 Conditional Init Constructs </H3>
+<!--docid::SEC11::-->
+<P>
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+</P><P>
+
+<DL COMPACT>
+<DT><CODE>$if</CODE>
+<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+<P>
+
+<DL COMPACT>
+<DT><CODE>mode</CODE>
+<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
+whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
+This may be used in conjunction
+with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
+the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
+Readline is starting out in <CODE>emacs</CODE> mode.
+<P>
+
+<DT><CODE>term</CODE>
+<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+<SAMP>`='</SAMP> is tested against both the full name of the terminal and
+the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
+allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
+for instance.
+<P>
+
+<DT><CODE>application</CODE>
+<DD>The <VAR>application</VAR> construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the <VAR>application name</VAR>, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+</pre></td></tr></table></DL>
+<P>
+
+<DT><CODE>$endif</CODE>
+<DD>This command, as seen in the previous example, terminates an
+<CODE>$if</CODE> command.
+<P>
+
+<DT><CODE>$else</CODE>
+<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
+the test fails.
+<P>
+
+<DT><CODE>$include</CODE>
+<DD>This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
+<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
+</pre></td></tr></table></DL>

+<H2> 1.5 Readline vi Mode </H2>
+<!--docid::SEC22::-->
+<P>
+
+While the Readline library does not have a full set of <CODE>vi</CODE>
+editing functions, it does contain enough to allow simple editing
+of the line.  The Readline <CODE>vi</CODE> mode behaves as specified in
+the POSIX standard.
+</P><P>
+
+In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
+editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
+when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
+The Readline default is <CODE>emacs</CODE> mode.
+</P><P>
+
+When you enter a line in <CODE>vi</CODE> mode, you are already placed in
+`insertion' mode, as if you had typed an <SAMP>`i'</SAMP>.  Pressing <KBD>ESC</KBD>
+switches you into `command' mode, where you can edit the text of the
+line with the standard <CODE>vi</CODE> movement keys, move to previous
+history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and
+so forth.

+<LI>
+PREAMBLE
+<P>
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document <EM>free</EM> in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+</P><P>
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+</P><P>
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+</P><P>
+
+<LI>
+APPLICABILITY AND DEFINITIONS
+<P>
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The "Document", below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as "you".  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+</P><P>
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+</P><P>
+
+A "Secondary Section" is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+</P><P>
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+</P><P>
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+</P><P>
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not "Transparent" is called "Opaque".
+</P><P>
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input
+format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available
+<FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification.  Examples
+of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and
+<FONT SIZE="-1">JPG</FONT>.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or
+<FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are
+not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>,
+PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for
+output purposes only.
+</P><P>
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+</P><P>
+
+The "publisher" means any person or entity that distributes copies
+of the Document to the public.
+</P><P>
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+</P><P>
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+</P><P>
+
+<LI>
+VERBATIM COPYING
+<P>
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+</P><P>
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+</P><P>
+
+<LI>
+COPYING IN QUANTITY
+<P>
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+</P><P>
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+</P><P>
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+</P><P>
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+</P><P>
+
+<LI>
+MODIFICATIONS
+<P>
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+</P><P>
+
+<OL>
+<LI>
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+<P>
+
+<LI>
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+<P>
+
+<LI>
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+<P>
+
+<LI>
+Preserve all the copyright notices of the Document.
+<P>
+
+<LI>
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+<P>
+
+<LI>
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+<P>
+
+<LI>
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+<P>
+
+<LI>
+Include an unaltered copy of this License.
+<P>
+
+<LI>
+Preserve the section Entitled "History", Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page.  If
+there is no section Entitled "History" in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+<P>
+
+<LI>
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the "History" section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+<P>
+
+<LI>
+For any section Entitled "Acknowledgements" or "Dedications", Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+<P>
+
+<LI>
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+<P>
+
+<LI>
+Delete any section Entitled "Endorsements".  Such a section
+may not be included in the Modified Version.
+<P>
+
+<LI>
+Do not retitle any existing section to be Entitled "Endorsements" or
+to conflict in title with any Invariant Section.
+<P>
+
+<LI>
+Preserve any Warranty Disclaimers.
+</OL>
+<P>
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+</P><P>
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+</P><P>
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+</P><P>
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+</P><P>
+
+<LI>
+COMBINING DOCUMENTS
+<P>
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+</P><P>
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+</P><P>
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications".  You must delete all
+sections Entitled "Endorsements."
+</P><P>
+
+<LI>
+COLLECTIONS OF DOCUMENTS
+<P>
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+</P><P>
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+</P><P>
+
+<LI>
+AGGREGATION WITH INDEPENDENT WORKS
+<P>
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+</P><P>
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+</P><P>
+
+<LI>
+TRANSLATION
+<P>
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+</P><P>
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+</P><P>
+
+<LI>
+TERMINATION
+<P>
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+</P><P>
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+</P><P>
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+</P><P>
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+</P><P>
+
+<LI>
+FUTURE REVISIONS OF THIS LICENSE
+<P>
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time.  Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.  See
+<A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>.
+</P><P>
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation.  If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.  If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+</P><P>
+
+<LI>
+RELICENSING
+<P>
+
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works.  A
+public wiki that anybody can edit is an example of such a server.  A
+"Massive Multiauthor Collaboration" (or "MMC") contained in the

+
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+</P><P>
+
+"Incorporate" means to publish or republish a Document, in whole or
+in part, as part of another Document.
+</P><P>
+
+An MMC is "eligible for relicensing" if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,

+
+1.1 Introduction to Line Editing
+================================
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+   The text `C-k' is read as `Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+   The text `M-k' is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed.  The Meta key is labeled <ALT> on many keyboards.  On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key.  The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+   If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+_first_, and then typing <k>.  Either process is known as "metafying"
+the <k> key.
+
+   The text `M-C-k' is read as `Meta-Control-k' and describes the
+character produced by "metafying" `C-k'.
+
+   In addition, several keys have their own names.  Specifically,
+<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
+when seen in this text, or in an init file (*note Readline Init File::).
+If your keyboard lacks a <LFD> key, typing <C-j> will produce the
+desired character.  The <RET> key may be labeled <Return> or <Enter> on
+some keyboards.

+
+1.2 Readline Interaction
+========================
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press <RET>.  You do not have to be at the end of
+the line to press <RET>; the entire line is accepted regardless of the
+location of the cursor within the line.

+* Readline Killing Commands::	How to delete text, and how to get it back!

+* Searching::			Searching through previous lines.

+
+1.2.1 Readline Bare Essentials
+------------------------------
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your erase
+character to back up and delete the mistyped character.
+
+   Sometimes you may mistype a character, and not notice the error
+until you have typed several other characters.  In that case, you can
+type `C-b' to move the cursor to the left, and then correct your
+mistake.  Afterwards, you can move the cursor to the right with `C-f'.
+
+   When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are `pushed over' to make room
+for the text that you have inserted.  Likewise, when you delete text
+behind the cursor, characters to the right of the cursor are `pulled
+back' to fill in the blank space created by the removal of the text.  A
+list of the bare essentials for editing the text of an input line
+follows.
+
+`C-b'
+     Move back one character.
+
+`C-f'
+     Move forward one character.
+
+<DEL> or <Backspace>
+     Delete the character to the left of the cursor.
+
+`C-d'
+     Delete the character underneath the cursor.
+
+Printing characters
+     Insert the character into the line at the cursor.
+
+`C-_' or `C-x C-u'
+     Undo the last editing command.  You can undo all the way back to an
+     empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like `C-d', rather than the
+character to the left of the cursor.)

+
+1.2.2 Readline Movement Commands
+--------------------------------
+
+The above table describes the most basic keystrokes that you need in
+order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to `C-b', `C-f', `C-d', and
+<DEL>.  Here are some commands for moving more rapidly about the line.
+
+`C-a'
+     Move to the start of the line.
+
+`C-e'
+     Move to the end of the line.
+
+`M-f'
+     Move forward a word, where a word is composed of letters and
+     digits.
+
+`M-b'
+     Move backward a word.
+
+`C-l'
+     Clear the screen, reprinting the current line at the top.
+
+   Notice how `C-f' moves forward a character, while `M-f' moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+

+
+1.2.3 Readline Killing Commands
+-------------------------------
+
+"Killing" text means to delete the text from the line, but to save it
+away for later use, usually by "yanking" (re-inserting) it back into
+the line.  (`Cut' and `paste' are more recent jargon for `kill' and
+`yank'.)
+
+   If the description for a command says that it `kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+   When you use a kill command, the text is saved in a "kill-ring".
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.  
+
+   Here is the list of commands for killing text.
+
+`C-k'
+     Kill the text from the current cursor position to the end of the
+     line.
+
+`M-d'
+     Kill from the cursor to the end of the current word, or, if between
+     words, to the end of the next word.  Word boundaries are the same
+     as those used by `M-f'.
+
+`M-<DEL>'
+     Kill from the cursor the start of the current word, or, if between
+     words, to the start of the previous word.  Word boundaries are the
+     same as those used by `M-b'.
+
+`C-w'
+     Kill from the cursor to the previous whitespace.  This is
+     different than `M-<DEL>' because the word boundaries differ.
+
+
+   Here is how to "yank" the text back into the line.  Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+`C-y'
+     Yank the most recently killed text back into the buffer at the
+     cursor.
+
+`M-y'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `C-y' or `M-y'.
+
+
+File: rluserman.info,  Node: Readline Arguments,  Next: Searching,  Prev: Readline Killing Commands,  Up: Readline Interaction
+
+1.2.4 Readline Arguments
+------------------------
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type `M-- C-k'.
+
+   The general way to pass numeric arguments to a command is to type
+meta digits before the command.  If the first `digit' typed is a minus
+sign (`-'), then the sign of the argument will be negative.  Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command.  For example, to give
+the `C-d' command an argument of 10, you could type `M-1 0 C-d', which
+will delete the next ten characters on the input line.
+
+
+File: rluserman.info,  Node: Searching,  Prev: Readline Arguments,  Up: Readline Interaction
+
+1.2.5 Searching for Commands in the History
+-------------------------------------------
+
+Readline provides commands for searching through the command history
+for lines containing a specified string.  There are two search modes:
+"incremental" and "non-incremental".
+
+   Incremental searches begin before the user has finished typing the
+search string.  As each character of the search string is typed,
+Readline displays the next entry from the history matching the string
+typed so far.  An incremental search requires only as many characters
+as needed to find the desired history entry.  To search backward in the
+history for a particular string, type `C-r'.  Typing `C-s' searches
+forward through the history.  The characters present in the value of
+the `isearch-terminators' variable are used to terminate an incremental
+search.  If that variable has not been assigned a value, the <ESC> and
+`C-J' characters will terminate an incremental search.  `C-g' will
+abort an incremental search and restore the original line.  When the
+search is terminated, the history entry containing the search string
+becomes the current line.
+
+   To find other matching entries in the history list, type `C-r' or
+`C-s' as appropriate.  This will search backward or forward in the
+history for the next entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate the
+search and execute that command.  For instance, a <RET> will terminate
+the search and accept the line, thereby executing the command from the
+history list.  A movement command will terminate the search, make the
+last line found the current line, and begin editing.
+
+   Readline remembers the last incremental search string.  If two
+`C-r's are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+   Non-incremental searches read the entire search string before
+starting to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.

+
+1.3 Readline Init File
+======================
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.  Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory.  The name of this file is taken from the value of the
+environment variable `INPUTRC'.  If that variable is unset, the default
+is `~/.inputrc'.  If that file does not exist or cannot be read, the
+ultimate default is `/etc/inputrc'.
+
+   When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+   In addition, the `C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+* Menu:
+
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+
+* Conditional Init Constructs::	Conditional key bindings in the inputrc file.
+
+* Sample Init File::		An example inputrc file.
+
+
+File: rluserman.info,  Node: Readline Init File Syntax,  Next: Conditional Init Constructs,  Up: Readline Init File
+
+1.3.1 Readline Init File Syntax
+-------------------------------
+
+There are only a few basic constructs allowed in the Readline init
+file.  Blank lines are ignored.  Lines beginning with a `#' are
+comments.  Lines beginning with a `$' indicate conditional constructs
+(*note Conditional Init Constructs::).  Other lines denote variable
+settings and key bindings.
+
+Variable Settings
+     You can modify the run-time behavior of Readline by altering the
+     values of variables in Readline using the `set' command within the
+     init file.  The syntax is simple:
+
+          set VARIABLE VALUE
+
+     Here, for example, is how to change from the default Emacs-like
+     key binding to use `vi' line editing commands:
+
+          set editing-mode vi
+
+     Variable names and values, where appropriate, are recognized
+     without regard to case.  Unrecognized variable names are ignored.
+
+     Boolean variables (those that can be set to on or off) are set to
+     on if the value is null or empty, ON (case-insensitive), or 1.
+     Any other value results in the variable being set to off.
+
+     A great deal of run-time behavior is changeable with the following
+     variables.
+
+    `bell-style'
+          Controls what happens when Readline wants to ring the
+          terminal bell.  If set to `none', Readline never rings the
+          bell.  If set to `visible', Readline uses a visible bell if
+          one is available.  If set to `audible' (the default),
+          Readline attempts to ring the terminal's bell.
+
+    `bind-tty-special-chars'
+          If set to `on', Readline attempts to bind the control
+          characters treated specially by the kernel's terminal driver
+          to their Readline equivalents.
+
+    `comment-begin'
+          The string to insert at the beginning of the line when the
+          `insert-comment' command is executed.  The default value is
+          `"#"'.
+
+    `completion-display-width'
+          The number of screen columns used to display possible matches
+          when performing completion.  The value is ignored if it is
+          less than 0 or greater than the terminal screen width.  A
+          value of 0 will cause matches to be displayed one per line.
+          The default value is -1.
+
+    `completion-ignore-case'
+          If set to `on', Readline performs filename matching and
+          completion in a case-insensitive fashion.  The default value
+          is `off'.
+
+    `completion-map-case'
+          If set to `on', and COMPLETION-IGNORE-CASE is enabled,
+          Readline treats hyphens (`-') and underscores (`_') as
+          equivalent when performing case-insensitive filename matching
+          and completion.
+
+    `completion-prefix-display-length'
+          The length in characters of the common prefix of a list of
+          possible completions that is displayed without modification.
+          When set to a value greater than zero, common prefixes longer
+          than this value are replaced with an ellipsis when displaying
+          possible completions.
+
+    `completion-query-items'
+          The number of possible completions that determines when the
+          user is asked whether the list of possibilities should be
+          displayed.  If the number of possible completions is greater
+          than this value, Readline will ask the user whether or not he
+          wishes to view them; otherwise, they are simply listed.  This
+          variable must be set to an integer value greater than or
+          equal to 0.  A negative value means Readline should never ask.
+          The default limit is `100'.
+
+    `convert-meta'
+          If set to `on', Readline will convert characters with the
+          eighth bit set to an ASCII key sequence by stripping the
+          eighth bit and prefixing an <ESC> character, converting them
+          to a meta-prefixed key sequence.  The default value is `on'.
+
+    `disable-completion'
+          If set to `On', Readline will inhibit word completion.
+          Completion  characters will be inserted into the line as if
+          they had been mapped to `self-insert'.  The default is `off'.
+
+    `editing-mode'
+          The `editing-mode' variable controls which default set of key
+          bindings is used.  By default, Readline starts up in Emacs
+          editing mode, where the keystrokes are most similar to Emacs.
+          This variable can be set to either `emacs' or `vi'.
+
+    `echo-control-characters'
+          When set to `on', on operating systems that indicate they
+          support it, readline echoes a character corresponding to a
+          signal generated from the keyboard.  The default is `on'.
+
+    `enable-keypad'
+          When set to `on', Readline will try to enable the application
+          keypad when it is called.  Some systems need this to enable
+          the arrow keys.  The default is `off'.
+
+    `enable-meta-key'
+          When set to `on', Readline will try to enable any meta
+          modifier key the terminal claims to support when it is
+          called.  On many terminals, the meta key is used to send
+          eight-bit characters.  The default is `on'.
+
+    `expand-tilde'
+          If set to `on', tilde expansion is performed when Readline
+          attempts word completion.  The default is `off'.
+
+    `history-preserve-point'
+          If set to `on', the history code attempts to place the point
+          (the current cursor position) at the same location on each
+          history line retrieved with `previous-history' or
+          `next-history'.  The default is `off'.
+
+    `history-size'
+          Set the maximum number of history entries saved in the
+          history list.  If set to zero, the number of entries in the
+          history list is not limited.
+
+    `horizontal-scroll-mode'
+          This variable can be set to either `on' or `off'.  Setting it
+          to `on' means that the text of the lines being edited will
+          scroll horizontally on a single screen line when they are
+          longer than the width of the screen, instead of wrapping onto
+          a new screen line.  By default, this variable is set to `off'.
+
+    `input-meta'
+          If set to `on', Readline will enable eight-bit input (it will
+          not clear the eighth bit in the characters it reads),
+          regardless of what the terminal claims it can support.  The
+          default value is `off'.  The name `meta-flag' is a synonym
+          for this variable.
+
+    `isearch-terminators'
+          The string of characters that should terminate an incremental
+          search without subsequently executing the character as a
+          command (*note Searching::).  If this variable has not been
+          given a value, the characters <ESC> and `C-J' will terminate
+          an incremental search.
+
+    `keymap'
+          Sets Readline's idea of the current keymap for key binding
+          commands.  Acceptable `keymap' names are `emacs',
+          `emacs-standard', `emacs-meta', `emacs-ctlx', `vi', `vi-move',
+          `vi-command', and `vi-insert'.  `vi' is equivalent to
+          `vi-command'; `emacs' is equivalent to `emacs-standard'.  The
+          default value is `emacs'.  The value of the `editing-mode'
+          variable also affects the default keymap.
+
+    `mark-directories'
+          If set to `on', completed directory names have a slash
+          appended.  The default is `on'.
+
+    `mark-modified-lines'
+          This variable, when set to `on', causes Readline to display an
+          asterisk (`*') at the start of history lines which have been
+          modified.  This variable is `off' by default.
+
+    `mark-symlinked-directories'
+          If set to `on', completed names which are symbolic links to
+          directories have a slash appended (subject to the value of
+          `mark-directories').  The default is `off'.
+
+    `match-hidden-files'
+          This variable, when set to `on', causes Readline to match
+          files whose names begin with a `.' (hidden files) when
+          performing filename completion.  If set to `off', the leading
+          `.' must be supplied by the user in the filename to be
+          completed.  This variable is `on' by default.
+
+    `menu-complete-display-prefix'
+          If set to `on', menu completion displays the common prefix of
+          the list of possible completions (which may be empty) before
+          cycling through the list.  The default is `off'.
+
+    `output-meta'
+          If set to `on', Readline will display characters with the
+          eighth bit set directly rather than as a meta-prefixed escape
+          sequence.  The default is `off'.
+
+    `page-completions'
+          If set to `on', Readline uses an internal `more'-like pager
+          to display a screenful of possible completions at a time.
+          This variable is `on' by default.
+
+    `print-completions-horizontally'
+          If set to `on', Readline will display completions with matches
+          sorted horizontally in alphabetical order, rather than down
+          the screen.  The default is `off'.
+
+    `revert-all-at-newline'
+          If set to `on', Readline will undo all changes to history
+          lines before returning when `accept-line' is executed.  By
+          default, history lines may be modified and retain individual
+          undo lists across calls to `readline'.  The default is `off'.
+
+    `show-all-if-ambiguous'
+          This alters the default behavior of the completion functions.
+          If set to `on', words which have more than one possible
+          completion cause the matches to be listed immediately instead
+          of ringing the bell.  The default value is `off'.
+
+    `show-all-if-unmodified'
+          This alters the default behavior of the completion functions
+          in a fashion similar to SHOW-ALL-IF-AMBIGUOUS.  If set to
+          `on', words which have more than one possible completion
+          without any possible partial completion (the possible
+          completions don't share a common prefix) cause the matches to
+          be listed immediately instead of ringing the bell.  The
+          default value is `off'.
+
+    `skip-completed-text'
+          If set to `on', this alters the default completion behavior
+          when inserting a single match into the line.  It's only
+          active when performing completion in the middle of a word.
+          If enabled, readline does not insert characters from the
+          completion that match characters after point in the word
+          being completed, so portions of the word following the cursor
+          are not duplicated.  For instance, if this is enabled,
+          attempting completion when the cursor is after the `e' in
+          `Makefile' will result in `Makefile' rather than
+          `Makefilefile', assuming there is a single possible
+          completion.  The default value is `off'.
+
+    `visible-stats'
+          If set to `on', a character denoting a file's type is
+          appended to the filename when listing possible completions.
+          The default is `off'.
+
+
+Key Bindings
+     The syntax for controlling key bindings in the init file is
+     simple.  First you need to find the name of the command that you
+     want to change.  The following sections contain tables of the
+     command name, the default keybinding, if any, and a short
+     description of what the command does.
+
+     Once you know the name of the command, simply place on a line in
+     the init file the name of the key you wish to bind the command to,
+     a colon, and then the name of the command.  There can be no space
+     between the key name and the colon - that will be interpreted as
+     part of the key name.  The name of the key can be expressed in
+     different ways, depending on what you find most comfortable.
+
+     In addition to command names, readline allows keys to be bound to
+     a string that is inserted when the key is pressed (a MACRO).
+
+    KEYNAME: FUNCTION-NAME or MACRO
+          KEYNAME is the name of a key spelled out in English.  For
+          example:
+               Control-u: universal-argument
+               Meta-Rubout: backward-kill-word
+               Control-o: "> output"
+
+          In the above example, `C-u' is bound to the function
+          `universal-argument', `M-DEL' is bound to the function
+          `backward-kill-word', and `C-o' is bound to run the macro
+          expressed on the right hand side (that is, to insert the text
+          `> output' into the line).
+
+          A number of symbolic character names are recognized while
+          processing this key binding syntax: DEL, ESC, ESCAPE, LFD,
+          NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.
+
+    "KEYSEQ": FUNCTION-NAME or MACRO
+          KEYSEQ differs from KEYNAME above in that strings denoting an
+          entire key sequence can be specified, by placing the key
+          sequence in double quotes.  Some GNU Emacs style key escapes
+          can be used, as in the following example, but the special
+          character names are not recognized.
+
+               "\C-u": universal-argument
+               "\C-x\C-r": re-read-init-file
+               "\e[11~": "Function Key 1"
+
+          In the above example, `C-u' is again bound to the function
+          `universal-argument' (just as it was in the first example),
+          `C-x C-r' is bound to the function `re-read-init-file', and
+          `<ESC> <[> <1> <1> <~>' is bound to insert the text `Function
+          Key 1'.
+
+
+     The following GNU Emacs style escape sequences are available when
+     specifying key sequences:
+
+    `\C-'
+          control prefix
+
+    `\M-'
+          meta prefix
+
+    `\e'
+          an escape character
+
+    `\\'
+          backslash
+
+    `\"'
+          <">, a double quotation mark
+
+    `\''
+          <'>, a single quote or apostrophe
+
+     In addition to the GNU Emacs style escape sequences, a second set
+     of backslash escapes is available:
+
+    `\a'
+          alert (bell)
+
+    `\b'
+          backspace
+
+    `\d'
+          delete
+
+    `\f'
+          form feed
+
+    `\n'
+          newline
+
+    `\r'
+          carriage return
+
+    `\t'
+          horizontal tab
+
+    `\v'
+          vertical tab
+
+    `\NNN'
+          the eight-bit character whose value is the octal value NNN
+          (one to three digits)
+
+    `\xHH'
+          the eight-bit character whose value is the hexadecimal value
+          HH (one or two hex digits)
+
+     When entering the text of a macro, single or double quotes must be
+     used to indicate a macro definition.  Unquoted text is assumed to
+     be a function name.  In the macro body, the backslash escapes
+     described above are expanded.  Backslash will quote any other
+     character in the macro text, including `"' and `''.  For example,
+     the following binding will make `C-x \' insert a single `\' into
+     the line:
+          "\C-x\\": "\\"

+
+1.3.2 Conditional Init Constructs
+---------------------------------
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings
+and variable settings to be performed as the result of tests.  There
+are four parser directives used.
+
+`$if'
+     The `$if' construct allows bindings to be made based on the
+     editing mode, the terminal being used, or the application using
+     Readline.  The text of the test extends to the end of the line; no
+     characters are required to isolate it.
+
+    `mode'
+          The `mode=' form of the `$if' directive is used to test
+          whether Readline is in `emacs' or `vi' mode.  This may be
+          used in conjunction with the `set keymap' command, for
+          instance, to set bindings in the `emacs-standard' and
+          `emacs-ctlx' keymaps only if Readline is starting out in
+          `emacs' mode.
+
+    `term'
+          The `term=' form may be used to include terminal-specific key
+          bindings, perhaps to bind the key sequences output by the
+          terminal's function keys.  The word on the right side of the
+          `=' is tested against both the full name of the terminal and
+          the portion of the terminal name before the first `-'.  This
+          allows `sun' to match both `sun' and `sun-cmd', for instance.
+
+    `application'
+          The APPLICATION construct is used to include
+          application-specific settings.  Each program using the
+          Readline library sets the APPLICATION NAME, and you can test
+          for a particular value.  This could be used to bind key
+          sequences to functions useful for a specific program.  For
+          instance, the following command adds a key sequence that
+          quotes the current or previous word in Bash:
+               $if Bash
+               # Quote the current or previous word
+               "\C-xq": "\eb\"\ef\""
+               $endif
+
+`$endif'
+     This command, as seen in the previous example, terminates an `$if'
+     command.
+
+`$else'
+     Commands in this branch of the `$if' directive are executed if the
+     test fails.
+
+`$include'
+     This directive takes a single filename as an argument and reads
+     commands and bindings from that file.  For example, the following
+     directive reads from `/etc/inputrc':
+          $include /etc/inputrc
+

+Here is an example of an INPUTRC file.  This illustrates key binding,
+variable assignment, and conditional syntax.

+   This section describes Readline commands that may be bound to key
+sequences.  Command names without an accompanying key sequence are
+unbound by default.
+
+   In the following descriptions, "point" refers to the current cursor
+position, and "mark" refers to a cursor position saved by the
+`set-mark' command.  The text between the point and mark is referred to
+as the "region".

+
+1.4.1 Commands For Moving
+-------------------------
+
+`beginning-of-line (C-a)'
+     Move to the start of the current line.
+
+`end-of-line (C-e)'
+     Move to the end of the line.
+
+`forward-char (C-f)'

+     letters and digits.
+
+`backward-word (M-b)'
+     Move back to the start of the current or previous word.  Words are
+     composed of letters and digits.
+
+`clear-screen (C-l)'
+     Clear the screen and redraw the current line, leaving the current
+     line at the top of the screen.
+
+`redraw-current-line ()'
+     Refresh the current line.  By default, this is unbound.

+
+1.4.2 Commands For Manipulating The History
+-------------------------------------------
+
+`accept-line (Newline or Return)'
+     Accept the line regardless of where the cursor is.  If this line is
+     non-empty, it may be added to the history list for future recall
+     with `add_history()'.  If this line is a modified history line,
+     the history line is restored to its original state.
+
+`previous-history (C-p)'
+     Move `back' through the history list, fetching the previous
+     command.
+
+`next-history (C-n)'
+     Move `forward' through the history list, fetching the next command.
+
+`beginning-of-history (M-<)'
+     Move to the first line in the history.
+
+`end-of-history (M->)'
+     Move to the end of the input history, i.e., the line currently
+     being entered.
+
+`reverse-search-history (C-r)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary.  This is an incremental search.
+
+`forward-search-history (C-s)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary.  This is an incremental
+     search.
+
+`non-incremental-reverse-search-history (M-p)'
+     Search backward starting at the current line and moving `up'
+     through the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`non-incremental-forward-search-history (M-n)'
+     Search forward starting at the current line and moving `down'
+     through the the history as necessary using a non-incremental search
+     for a string supplied by the user.
+
+`history-search-forward ()'
+     Search forward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`history-search-backward ()'
+     Search backward through the history for the string of characters
+     between the start of the current line and the point.  This is a
+     non-incremental search.  By default, this command is unbound.
+
+`yank-nth-arg (M-C-y)'
+     Insert the first argument to the previous command (usually the
+     second word on the previous line) at point.  With an argument N,
+     insert the Nth word from the previous command (the words in the
+     previous command begin with word 0).  A negative argument inserts
+     the Nth word from the end of the previous command.  Once the
+     argument N is computed, the argument is extracted as if the `!N'
+     history expansion had been specified.
+
+`yank-last-arg (M-. or M-_)'
+     Insert last argument to the previous command (the last word of the
+     previous history entry).  With a numeric argument, behave exactly
+     like `yank-nth-arg'.  Successive calls to `yank-last-arg' move
+     back through the history list, inserting the last word (or the
+     word specified by the argument to the first call) of each line in
+     turn.  Any numeric argument supplied to these successive calls
+     determines the direction to move through the history.  A negative
+     argument switches the direction through the history (back or
+     forward).  The history expansion facilities are used to extract
+     the last argument, as if the `!$' history expansion had been
+     specified.

+
+1.4.3 Commands For Changing Text
+--------------------------------
+
+`delete-char (C-d)'
+     Delete the character at point.  If point is at the beginning of
+     the line, there are no characters in the line, and the last
+     character typed was not bound to `delete-char', then return EOF.
+
+`backward-delete-char (Rubout)'
+     Delete the character behind the cursor.  A numeric argument means
+     to kill the characters instead of deleting them.
+
+`forward-backward-delete-char ()'
+     Delete the character under the cursor, unless the cursor is at the
+     end of the line, in which case the character behind the cursor is
+     deleted.  By default, this is not bound to a key.
+
+`quoted-insert (C-q or C-v)'
+     Add the next character typed to the line verbatim.  This is how to
+     insert key sequences like `C-q', for example.
+
+`tab-insert (M-<TAB>)'
+     Insert a tab character.
+
+`self-insert (a, b, A, 1, !, ...)'
+     Insert yourself.
+
+`transpose-chars (C-t)'
+     Drag the character before the cursor forward over the character at
+     the cursor, moving the cursor forward as well.  If the insertion
+     point is at the end of the line, then this transposes the last two
+     characters of the line.  Negative arguments have no effect.
+
+`transpose-words (M-t)'
+     Drag the word before point past the word after point, moving point
+     past that word as well.  If the insertion point is at the end of
+     the line, this transposes the last two words on the line.
+
+`upcase-word (M-u)'
+     Uppercase the current (or following) word.  With a negative
+     argument, uppercase the previous word, but do not move the cursor.
+
+`downcase-word (M-l)'
+     Lowercase the current (or following) word.  With a negative
+     argument, lowercase the previous word, but do not move the cursor.
+
+`capitalize-word (M-c)'
+     Capitalize the current (or following) word.  With a negative
+     argument, capitalize the previous word, but do not move the cursor.
+
+`overwrite-mode ()'
+     Toggle overwrite mode.  With an explicit positive numeric argument,
+     switches to overwrite mode.  With an explicit non-positive numeric
+     argument, switches to insert mode.  This command affects only
+     `emacs' mode; `vi' mode does overwrite differently.  Each call to
+     `readline()' starts in insert mode.
+
+     In overwrite mode, characters bound to `self-insert' replace the
+     text at point rather than pushing the text to the right.
+     Characters bound to `backward-delete-char' replace the character
+     before point with a space.
+
+     By default, this command is unbound.
+
+
+
+File: rluserman.info,  Node: Commands For Killing,  Next: Numeric Arguments,  Prev: Commands For Text,  Up: Bindable Readline Commands
+
+1.4.4 Killing And Yanking
+-------------------------
+
+`kill-line (C-k)'
+     Kill the text from point to the end of the line.
+
+`backward-kill-line (C-x Rubout)'
+     Kill backward to the beginning of the line.
+
+`unix-line-discard (C-u)'
+     Kill backward from the cursor to the beginning of the current line.
+
+`kill-whole-line ()'
+     Kill all characters on the current line, no matter where point is.
+     By default, this is unbound.
+
+`kill-word (M-d)'
+     Kill from point to the end of the current word, or if between
+     words, to the end of the next word.  Word boundaries are the same
+     as `forward-word'.
+
+`backward-kill-word (M-<DEL>)'
+     Kill the word behind point.  Word boundaries are the same as
+     `backward-word'.
+
+`unix-word-rubout (C-w)'
+     Kill the word behind point, using white space as a word boundary.
+     The killed text is saved on the kill-ring.
+
+`unix-filename-rubout ()'
+     Kill the word behind point, using white space and the slash
+     character as the word boundaries.  The killed text is saved on the
+     kill-ring.
+
+`delete-horizontal-space ()'
+     Delete all spaces and tabs around point.  By default, this is
+     unbound.
+
+`kill-region ()'
+     Kill the text in the current region.  By default, this command is
+     unbound.
+
+`copy-region-as-kill ()'
+     Copy the text in the region to the kill buffer, so it can be yanked
+     right away.  By default, this command is unbound.
+
+`copy-backward-word ()'
+     Copy the word before point to the kill buffer.  The word
+     boundaries are the same as `backward-word'.  By default, this
+     command is unbound.
+
+`copy-forward-word ()'
+     Copy the word following point to the kill buffer.  The word
+     boundaries are the same as `forward-word'.  By default, this
+     command is unbound.
+
+`yank (C-y)'
+     Yank the top of the kill ring into the buffer at point.
+
+`yank-pop (M-y)'
+     Rotate the kill-ring, and yank the new top.  You can only do this
+     if the prior command is `yank' or `yank-pop'.
+
+
+File: rluserman.info,  Node: Numeric Arguments,  Next: Commands For Completion,  Prev: Commands For Killing,  Up: Bindable Readline Commands
+
+1.4.5 Specifying Numeric Arguments
+----------------------------------
+
+`digit-argument (M-0, M-1, ... M--)'
+     Add this digit to the argument already accumulating, or start a new
+     argument.  `M--' starts a negative argument.
+
+`universal-argument ()'
+     This is another way to specify an argument.  If this command is
+     followed by one or more digits, optionally with a leading minus
+     sign, those digits define the argument.  If the command is
+     followed by digits, executing `universal-argument' again ends the
+     numeric argument, but is otherwise ignored.  As a special case, if
+     this command is immediately followed by a character that is
+     neither a digit or minus sign, the argument count for the next
+     command is multiplied by four.  The argument count is initially
+     one, so executing this function the first time makes the argument
+     count four, a second time makes the argument count sixteen, and so
+     on.  By default, this is not bound to a key.
+

+
+1.4.6 Letting Readline Type For You
+-----------------------------------
+
+`complete (<TAB>)'
+     Attempt to perform completion on the text before point.  The
+     actual completion performed is application-specific.  The default
+     is filename completion.
+
+`possible-completions (M-?)'
+     List the possible completions of the text before point.  When
+     displaying completions, Readline sets the number of columns used
+     for display to the value of `completion-display-width', the value
+     of the environment variable `COLUMNS', or the screen width, in
+     that order.
+
+`insert-completions (M-*)'
+     Insert all completions of the text before point that would have
+     been generated by `possible-completions'.
+
+`menu-complete ()'
+     Similar to `complete', but replaces the word to be completed with
+     a single match from the list of possible completions.  Repeated
+     execution of `menu-complete' steps through the list of possible
+     completions, inserting each match in turn.  At the end of the list
+     of completions, the bell is rung (subject to the setting of
+     `bell-style') and the original text is restored.  An argument of N
+     moves N positions forward in the list of matches; a negative
+     argument may be used to move backward through the list.  This
+     command is intended to be bound to <TAB>, but is unbound by
+     default.
+
+`menu-complete-backward ()'
+     Identical to `menu-complete', but moves backward through the list
+     of possible completions, as if `menu-complete' had been given a
+     negative argument.
+
+`delete-char-or-list ()'
+     Deletes the character under the cursor if not at the beginning or
+     end of the line (like `delete-char').  If at the end of the line,
+     behaves identically to `possible-completions'.  This command is
+     unbound by default.
+
+

+File: rluserman.info,  Node: Keyboard Macros,  Next: Miscellaneous Commands,  Prev: Commands For Completion,  Up: Bindable Readline Commands
+
+1.4.7 Keyboard Macros
+---------------------
+
+`start-kbd-macro (C-x ()'
+     Begin saving the characters typed into the current keyboard macro.
+
+`end-kbd-macro (C-x ))'
+     Stop saving the characters typed into the current keyboard macro
+     and save the definition.
+
+`call-last-kbd-macro (C-x e)'
+     Re-execute the last keyboard macro defined, by making the
+     characters in the macro appear as if typed at the keyboard.
+
+
+
+File: rluserman.info,  Node: Miscellaneous Commands,  Prev: Keyboard Macros,  Up: Bindable Readline Commands
+
+1.4.8 Some Miscellaneous Commands
+---------------------------------
+
+`re-read-init-file (C-x C-r)'
+     Read in the contents of the INPUTRC file, and incorporate any
+     bindings or variable assignments found there.
+
+`abort (C-g)'
+     Abort the current editing command and ring the terminal's bell
+     (subject to the setting of `bell-style').
+
+`do-uppercase-version (M-a, M-b, M-X, ...)'
+     If the metafied character X is lowercase, run the command that is
+     bound to the corresponding uppercase character.
+
+`prefix-meta (<ESC>)'
+     Metafy the next character typed.  This is for keyboards without a
+     meta key.  Typing `<ESC> f' is equivalent to typing `M-f'.
+
+`undo (C-_ or C-x C-u)'
+     Incremental undo, separately remembered for each line.
+
+`revert-line (M-r)'
+     Undo all changes made to this line.  This is like executing the
+     `undo' command enough times to get back to the beginning.
+
+`tilde-expand (M-~)'
+     Perform tilde expansion on the current word.
+
+`set-mark (C-@)'
+     Set the mark to the point.  If a numeric argument is supplied, the
+     mark is set to that position.
+
+`exchange-point-and-mark (C-x C-x)'
+     Swap the point with the mark.  The current cursor position is set
+     to the saved position, and the old cursor position is saved as the
+     mark.
+
+`character-search (C-])'
+     A character is read and point is moved to the next occurrence of
+     that character.  A negative count searches for previous
+     occurrences.
+
+`character-search-backward (M-C-])'
+     A character is read and point is moved to the previous occurrence
+     of that character.  A negative count searches for subsequent
+     occurrences.
+
+`skip-csi-sequence ()'
+     Read enough characters to consume a multi-key sequence such as
+     those defined for keys like Home and End.  Such sequences begin
+     with a Control Sequence Indicator (CSI), usually ESC-[.  If this
+     sequence is bound to "\e[", keys producing such sequences will
+     have no effect unless explicitly bound to a readline command,
+     instead of inserting stray characters into the editing buffer.
+     This is unbound by default, but usually bound to ESC-[.
+
+`insert-comment (M-#)'
+     Without a numeric argument, the value of the `comment-begin'
+     variable is inserted at the beginning of the current line.  If a
+     numeric argument is supplied, this command acts as a toggle:  if
+     the characters at the beginning of the line do not match the value
+     of `comment-begin', the value is inserted, otherwise the
+     characters in `comment-begin' are deleted from the beginning of
+     the line.  In either case, the line is accepted as if a newline
+     had been typed.
+
+`dump-functions ()'
+     Print all of the functions and their key bindings to the Readline
+     output stream.  If a numeric argument is supplied, the output is
+     formatted in such a way that it can be made part of an INPUTRC
+     file.  This command is unbound by default.
+
+`dump-variables ()'
+     Print all of the settable variables and their values to the
+     Readline output stream.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`dump-macros ()'
+     Print all of the Readline key sequences bound to macros and the
+     strings they output.  If a numeric argument is supplied, the
+     output is formatted in such a way that it can be made part of an
+     INPUTRC file.  This command is unbound by default.
+
+`emacs-editing-mode (C-e)'
+     When in `vi' command mode, this causes a switch to `emacs' editing
+     mode.
+
+`vi-editing-mode (M-C-j)'
+     When in `emacs' editing mode, this causes a switch to `vi' editing
+     mode.
+
+
+
+File: rluserman.info,  Node: Readline vi Mode,  Prev: Bindable Readline Commands,  Up: Command Line Editing
+
+1.5 Readline vi Mode
+====================
+
+While the Readline library does not have a full set of `vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline `vi' mode behaves as specified in the POSIX standard.
+
+   In order to switch interactively between `emacs' and `vi' editing
+modes, use the command `M-C-j' (bound to emacs-editing-mode when in
+`vi' mode and to vi-editing-mode in `emacs' mode).  The Readline
+default is `emacs' mode.
+
+   When you enter a line in `vi' mode, you are already placed in
+`insertion' mode, as if you had typed an `i'.  Pressing <ESC> switches
+you into `command' mode, where you can edit the text of the line with
+the standard `vi' movement keys, move to previous history lines with
+`k' and subsequent lines with `j', and so forth.

+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.
+     We recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it
+     can be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You
+     accept the license if you copy, modify or distribute the work in a
+     way requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in
+     the notice that says that the Document is released under this
+     License.  If a section does not fit the above definition of
+     Secondary then it is not allowed to be designated as Invariant.
+     The Document may contain zero Invariant Sections.  If the Document
+     does not identify any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images
+     composed of pixels) generic paint programs or (for drawings) some
+     widely available drawing editor, and that is suitable for input to
+     text formatters or for automatic translation to a variety of
+     formats suitable for input to text formatters.  A copy made in an
+     otherwise Transparent file format whose markup, or absence of
+     markup, has been arranged to thwart or discourage subsequent
+     modification by readers is not Transparent.  An image format is
+     not Transparent if used for any substantial amount of text.  A
+     copy that is not "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and
+     standard-conforming simple HTML, PostScript or PDF designed for
+     human modification.  Examples of transparent image formats include
+     PNG, XCF and JPG.  Opaque formats include proprietary formats that
+     can be read and edited only by proprietary word processors, SGML or
+     XML for which the DTD and/or processing tools are not generally
+     available, and the machine-generated HTML, PostScript or PDF
+     produced by some word processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow
+     the conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the
+     title equally prominent and visible.  You may add other material
+     on the covers in addition.  Copying with changes limited to the
+     covers, as long as they preserve the title of the Document and
+     satisfy these conditions, can be treated as verbatim copying in
+     other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a
+     machine-readable Transparent copy along with each Opaque copy, or
+     state in or with each Opaque copy a computer-network location from
+     which the general network-using public has access to download
+     using public-standard network protocols a complete Transparent
+     copy of the Document, free of added material.  If you use the
+     latter option, you must take reasonably prudent steps, when you
+     begin distribution of Opaque copies in quantity, to ensure that
+     this Transparent copy will remain thus accessible at the stated
+     location until at least one year after the last time you
+     distribute an Opaque copy (directly or through your agents or
+     retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of
+     copies, to give them a chance to provide you with an updated
+     version of the Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with
+     the Modified Version filling the role of the Document, thus
+     licensing distribution and modification of the Modified Version to
+     whoever possesses a copy of it.  In addition, you must do these
+     things in the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of
+          previous versions (which should, if there were any, be listed
+          in the History section of the Document).  You may use the
+          same title as a previous version if the original publisher of
+          that version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on
+          the Title Page.  If there is no section Entitled "History" in
+          the Document, create one stating the title, year, authors,
+          and publisher of the Document as given on its Title Page,
+          then add an item describing the Modified Version as stated in
+          the previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in
+          the "History" section.  You may omit a network location for a
+          work that was published at least four years before the
+          Document itself, or if the original publisher of the version
+          it refers to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the
+          section all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document,
+          unaltered in their text and in their titles.  Section numbers
+          or the equivalent are not considered part of the section
+          titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option
+     designate some or all of these sections as invariant.  To do this,
+     add their titles to the list of Invariant Sections in the Modified
+     Version's license notice.  These titles must be distinct from any
+     other section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end
+     of the list of Cover Texts in the Modified Version.  Only one
+     passage of Front-Cover Text and one of Back-Cover Text may be
+     added by (or through arrangements made by) any one entity.  If the
+     Document already includes a cover text for the same cover,
+     previously added by you or by arrangement made by the same entity
+     you are acting on behalf of, you may not add another; but you may
+     replace the old one, on explicit permission from the previous
+     publisher that added the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination
+     all of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the
+     documents in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow
+     this License in all other respects regarding verbatim copying of
+     that document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of
+     a storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly
+     and finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from
+     you under this License.  If your rights have been terminated and
+     not permanently reinstated, receipt of a copy of some or all of
+     the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     `http://www.gnu.org/copyleft/'.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If
+     the Document does not specify a version number of this License,
+     you may choose any version ever published (not as a draft) by the
+     Free Software Foundation.  If the Document specifies that a proxy
+     can decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+usage="Usage: $program [OPTION]... FILE...
+
+Run each Texinfo or LaTeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language (LaTeX or Texinfo).
+
+Makeinfo is used to perform Texinfo macro expansion before running TeX
+when needed.
+
+Operation modes:
+  -b, --batch         no interaction
+  -c, --clean         remove all auxiliary files
+  -D, --debug         turn on shell debugging (set -x)
+  -h, --help          display this help and exit successfully
+  -o, --output=OFILE  leave output in OFILE (implies --clean);
+                      Only one input FILE may be specified in this case
+  -q, --quiet         no output unless errors (implies --batch)
+  -s, --silent        same as --quiet
+  -v, --version       display version information and exit successfully
+  -V, --verbose       report on what is done
+
+TeX tuning:
+  -@                   use @input instead of \input; for preloaded Texinfo
+  -e, -E, --expand     force macro expansion using makeinfo
+  -I DIR               search DIR for Texinfo files
+  -l, --language=LANG  specify the LANG of FILE (LaTeX or Texinfo)
+  -p, --pdf            use pdftex or pdflatex for processing
+  -t, --texinfo=CMD    insert CMD after @setfilename in copy of input file
+                       multiple values accumulate
+
+The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
+TEX (or PDFTEX), and TEXINDEX environment variables are used to run
+those commands, if they are set.

+#     some global string/hash/array variables
+# 2.) For larger changes, reimplement one of the T2H_DEFAULT_<fnc>* routines,
+#     give them another name, and assign them to the respective
+#     $T2H_<fnc> variable.
+
+# As a general interface, the hashes T2H_HREF, T2H_NAME, T2H_NODE hold 
+# href, html-name, node-name of
+# This     -- current section (resp. html page)

+# Contents -- Table of contents
+# Overview -- Short table of contents
+# Index    -- Index page
+# About    -- page which explain "navigation buttons"
+# First    -- first node 
+# Last     -- last node
+#
+# Whether or not the following hash values are set, depends on the context 
+# (all values are w.r.t. 'This' section)

+% As a special exception, when this file is read by TeX when processing
+% a Texinfo source document, you may use the result without
+% restriction.  (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+%   ftp://tug.org/tex/texinfo.tex
+%     (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo@gnu.org.  Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem.  Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+To: chet@po.cwru.edu
+Subject: new readline example
+Message-ID: <14094.12094.527305.199695@mrclean.Stanford.EDU>
+
+Chet,
+
+I've been using readline 4.0. Specifically, I've been using the perl
+version Term::ReadLine::Gnu. It works great.
+
+Anyway, I've been playing around the alternate interface and I wanted
+to contribute a little C program, callback.c, to you that you could
+use as an example of the alternate interface in the /examples
+directory of the readline distribution.
+
+My example shows how, using the alternate interface, you can
+interactively change the prompt (which is very nice imo). Also, I
+point out that you must roll your own terminal setting when using the
+alternate interface because readline depreps (using your parlance) the
+terminal while in the user callback. I try to demostrate what I mean
+with an example. I've included the program below.
+
+To compile, I just put the program in the examples directory and made
+the appropriate changes to the EXECUTABLES and OBJECTS line and added
+an additional target 'callback'.
+
+I compiled on my Sun Solaris2.6 box using Sun's cc.
+
+Let me know what you think.
+

+/* This little examples demonstrates the alternate interface to using readline.
+ * In the alternate interface, the user maintains control over program flow and
+ * only calls readline when STDIN is readable. Using the alternate interface,
+ * you can do anything else while still using readline (like talking to a
+ * network or another program) without blocking.
+ *
+ * Specifically, this program highlights two importants features of the
+ * alternate interface. The first is the ability to interactively change the
+ * prompt, which can't be done using the regular interface since rl_prompt is
+ * read-only.
+ * 
+ * The second feature really highlights a subtle point when using the alternate
+ * interface. That is, readline will not alter the terminal when inside your
+ * callback handler. So let's so, your callback executes a user command that
+ * takes a non-trivial amount of time to complete (seconds). While your
+ * executing the command, the user continues to type keystrokes and expects them
+ * to be re-echoed on the new prompt when it returns. Unfortunately, the default
+ * terminal configuration doesn't do this. After the prompt returns, the user
+ * must hit one additional keystroke and then will see all of his previous
+ * keystrokes. To illustrate this, compile and run this program. Type "sleep" at
+ * the prompt and then type "bar" before the prompt returns (you have 3
+ * seconds). Notice how "bar" is re-echoed on the prompt after the prompt
+ * returns? This is what you expect to happen. Now comment out the 4 lines below
+ * the line that says COMMENT LINE BELOW. Recompile and rerun the program and do
+ * the same thing. When the prompt returns, you should not see "bar". Now type
+ * "f", see how "barf" magically appears? This behavior is un-expected and not
+ * desired.

+Subject: fgets(stdin) --> readline() redirector
+To: chet@po.cwru.edu
+
+Hi Chet,
+
+Here is something you may find useful enough to include in the readline
+distribution.  It is a shared library that redirects calls to fgets(stdin)
+to readline() via LD_PRELOAD, and it supports a custom prompt and list of
+command names.  Many people have asked me for this file, so I thought I'd
+pass it your way in hope of just including it with readline to begin with.
+
+Best Regards,
+
+-Harold

+  FILE NAME:    fgets.c                  TARGET:   libfgets.so
+  AUTHOR:       Harold Levy              VERSION:  1.0
+                hlevy@synopsys.com
+  
+  ABSTRACT:  Customize fgets() behavior via LD_PRELOAD in the following ways:
+  
+    -- If fgets(stdin) is called, redirect to GNU readline() to obtain
+       command-line editing, file-name completion, history, etc.
+  
+    -- A list of commands for command-name completion can be configured by
+       setting the environment-variable FGETS_COMMAND_FILE to a file containing
+       the list of commands to be used.
+  
+    -- Command-line editing with readline() works best when the prompt string
+       is known; you can set this with the FGETS_PROMPT environment variable.
+  
+    -- There special strings that libfgets will interpret as internal commands:
+  
+           _fgets_reset_    reset the command list
+  
+           _fgets_dump_     dump status
+  
+           _fgets_debug_    toggle debug messages
+
+  HOW TO BUILD:  Here are examples of how to build libfgets.so on various
+  platforms; you will have to add -I and -L flags to configure access to
+  the readline header and library files.
+
+  (32-bit builds with gcc)
+  AIX:   gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap
+  HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline
+  Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline
+  SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline
+
+  (64-bit builds without gcc)
+  SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \
+           -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline
+  
+  HOW TO USE:  Different operating systems have different levels of support
+  for the LD_PRELOAD concept.  The generic method for 32-bit platforms is to
+  put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths)
+  in the LD_PRELOAD environment variable, and to put their parent directories
+  in the LD_LIBRARY_PATH environment variable.  Unfortunately there is no
+  generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have
+  to build both 32-bit and 64-bit libfgets and libreadline libraries, and
+  use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and
+  library_path configurations (a mix of 32-bit and 64-bit calls are made under
+  64-bit SunOS).
+  
+  EXAMPLE WRAPPER:  Here is an example shell script wrapper around the
+  program "foo" that uses fgets() for command-line input:
+
+      #!/bin/csh
+      #### replace this with the libtermcap.so directory:
+      set dir1 = "/usr/lib"
+      #### replace this with the libfgets.so directory:
+      set dir2 = "/usr/fgets"
+      #### replace this with the libreadline.so directory:
+      set dir3 = "/usr/local/lib"
+      set lib1 = "${dir1}/libtermcap.so"
+      set lib2 = "${dir2}/libfgets.so"
+      set lib3 = "${dir3}/libreadline.so"
+      if ( "${?LD_PRELOAD}" ) then
+        setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}"
+      else
+        setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}"
+      endif
+      if ( "${?LD_LIBRARY_PATH}" ) then
+        setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}"
+      else
+        setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}"
+      endif
+      setenv FGETS_COMMAND_FILE "${dir2}/foo.commands"
+      setenv FGETS_PROMPT       "foo> "
+      exec "foo" $*

+rlfe (ReadLine Front-End) is a "universal wrapper" around readline.
+You specify an interactive program to run (typically a shell), and
+readline is used to edit input lines.
+
+There are other such front-ends; what distinguishes this one is that
+it monitors the state of the inferior pty, and if the inferior program
+switches its terminal to raw mode, then rlfe passes your characters
+through directly.  This basically means you can run your entire
+session (including bash and terminal-mode emacs) under rlfe.
+
+FEATURES
+
+* Can use all readline commands (and history) in commands that
+read input lines in "canonical mode" - even 'cat'!
+
+* Automatically switches between "readline-editing mode" and "raw mode"
+depending on the terminal mode.  If the inferior program invokes
+readline itself, it will do its own line editing.  (The inferior
+readline will not know about rlfe, and it will have its own history.)
+You can even run programs like 'emavs -nw' and 'vi' under rlfe.
+The goal is you could leave rlfe always on without even knowing
+about it.  (We're not quite there, but it works tolerably well.)
+
+* The input line (after any prompt) is changed to bold-face.
+
+INSTALL
+
+The usual: ./configure && make && make install
+
+Note so far rlfe has only been tested on GNU Linux (Fedora Core 2)
+and Mac OS X (10.3).
+
+This assumes readline header files and libraries are in the default
+places.  If not, you can create a link named readline pointing to the
+readline sources.  To link with libreadline.a and libhistory.a
+you can copy or link them, or add LDFLAGS='-/path/to/readline' to
+the make command-line.
+
+USAGE
+
+Just run it.  That by default runs bash.  You can run some other
+command by giving it as command-line arguments.
+
+There are a few tweaks:  -h allows you to name the history file,
+and -s allows you to specify its size.  It default to "emacs" mode,
+but if the the environment variable EDITOR is set to "vi" that
+mode is chosen.
+
+ISSUES
+
+* The mode switching depends on the terminal mode set by the inferior
+program.  Thus ssh/telnet/screen-type programs will typically be in
+raw mode, so rlfe won't be much use, even if remote programs run in
+canonical mode.  The work-around is to run rlfe on the remote end.
+
+* Echo supression and prompt recognition are somewhat fragile.
+(A protocol so that the o/s tty code can reliably communicate its
+state to rlfe could solve this problem, and the previous one.)
+
+* See the intro to rlfe.c for more notes.
+
+* Assumes a VT100-compatible terminal, though that could be generalized
+if anybody cares.
+
+* Requires ncurses.
+
+* It would be useful to integrate rlfe's logic in a terminal emulator.
+That would make it easier to reposition the edit position with a mouse,
+integrate cut-and-paste with the system clipboard, and more robustly
+handle escape sequence and multi-byte characters more robustly.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

+  --with-pty-mode=mode    default mode for ptys
+  --with-pty-group=group  default group for ptys
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+/* PROBLEMS/TODO:
+ *
+ * Only tested under GNU/Linux and Mac OS 10.x;  needs to be ported.
+ *
+ * Switching between line-editing-mode vs raw-char-mode depending on
+ * what tcgetattr returns is inherently not robust, plus it doesn't
+ * work when ssh/telnetting in.  A better solution is possible if the
+ * tty system can send in-line escape sequences indicating the current
+ * mode, echo'd input, etc.  That would also allow a user preference
+ * to set different colors for prompt, input, stdout, and stderr.
+ *
+ * When running mc -c under the Linux console, mc does not recognize
+ * mouse clicks, which mc does when not running under rlfe.
+ *
+ * Pasting selected text containing tabs is like hitting the tab character,
+ * which invokes readline completion.  We don't want this.  I don't know
+ * if this is fixable without integrating rlfe into a terminal emulator.
+ *
+ * Echo suppression is a kludge, but can only be avoided with better kernel
+ * support: We need a tty mode to disable "real" echoing, while still
+ * letting the inferior think its tty driver to doing echoing.
+ * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
+ *
+ * The latest readline may have some hooks we can use to avoid having
+ * to back up the prompt. (See HAVE_ALREADY_PROMPTED.)
+ *
+ * Desirable readline feature:  When in cooked no-echo mode (e.g. password),
+ * echo characters are they are types with '*', but remove them when done.
+ *
+ * Asynchronous output while we're editing an input line should be
+ * inserted in the output view *before* the input line, so that the
+ * lines being edited (with the prompt) float at the end of the input.
+ *
+ * A "page mode" option to emulate more/less behavior:  At each page of
+ * output, pause for a user command.  This required parsing the output
+ * to keep track of line lengths.  It also requires remembering the
+ * output, if we want an option to scroll back, which suggests that
+ * this should be integrated with a terminal emulator like xterm.

+ * This is an implementation of wcwidth() and wcswidth() (defined in
+ * IEEE Std 1002.1-2001) for Unicode.
+ *
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
+ *
+ * In fixed-width output devices, Latin characters all occupy a single
+ * "cell" position of equal width, whereas ideographic CJK characters
+ * occupy two such cells. Interoperability between terminal-line
+ * applications and (teletype-style) character terminals using the
+ * UTF-8 encoding requires agreement on which character should advance
+ * the cursor by how many cell positions. No established formal
+ * standards exist at present on which Unicode character shall occupy
+ * how many cell positions on character terminals. These routines are
+ * a first attempt of defining such behavior based on simple rules
+ * applied to data provided by the Unicode Consortium.
+ *
+ * For some graphical characters, the Unicode standard explicitly
+ * defines a character-cell width via the definition of the East Asian
+ * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
+ * In all these cases, there is no ambiguity about which width a
+ * terminal shall use. For characters in the East Asian Ambiguous (A)
+ * class, the width choice depends purely on a preference of backward
+ * compatibility with either historic CJK or Western practice.
+ * Choosing single-width for these characters is easy to justify as
+ * the appropriate long-term solution, as the CJK practice of
+ * displaying these characters as double-width comes from historic
+ * implementation simplicity (8-bit encoded characters were displayed
+ * single-width and 16-bit ones double-width, even for Greek,
+ * Cyrillic, etc.) and not any typographic considerations.
+ *
+ * Much less clear is the choice of width for the Not East Asian
+ * (Neutral) class. Existing practice does not dictate a width for any
+ * of these characters. It would nevertheless make sense
+ * typographically to allocate two character cells to characters such
+ * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
+ * represented adequately with a single-width glyph. The following
+ * routines at present merely assign a single-cell width to all
+ * neutral characters, in the interest of simplicity. This is not
+ * entirely satisfactory and should be reconsidered before
+ * establishing a formal standard in this area. At the moment, the
+ * decision which Not East Asian (Neutral) characters should be
+ * represented by double-width glyphs cannot yet be answered by
+ * applying a simple rule from the Unicode database content. Setting
+ * up a proper standard for the behavior of UTF-8 character terminals
+ * will require a careful analysis not only of each Unicode character,
+ * but also of each presentation form, something the author of these
+ * routines has avoided to do so far.
