+NOTE:  The string <release> should be replaced with
+       the appropriate release number of RTEMS.
+
+This file only discusses the installation of .tgz files.
+For more detailed information on the installation of RTEMS,
+refer to the Release Notes manual in the file 
+/pub/rtems/releases/<release>/doc/c_or_ada/relnotes.tgz on
+lancelot.gcs.redstone.army.mil.
+
+UNCOMPRESSING .tgz FILES
+===========================
+Many of the files found in this directory and its subdirectories 
+are gzip'ed, tar archive files.  These files have the ".tgz"
+extension.  They were compressed with gzip version 1.2.4.  
+
+Use a command sequence similar to the following to uncompress each
+file:
+
+   gzcat FILE.tgz | tar xvof -
+
+where FILE.tgz is the file to be installed.  This procedure will
+extract the files in the archive into the current directory.
+All of the .tgz files associated with this release RTEMS will
+place their contents in a subdirectory rtems-<release> in the current
+directory.
+
+If you are unsure of what is in an RTEMS archive file, then use
+the following command sequence to get a listing of the contents:
+
+   gzcat FILE.tgz | tar tvf -
+
+NOTES:  
+
+(1) The "-o" option to tar is included on the tar command line
+    so that the user extracting the tar archive will own the extracted
+    files.
+
+(2) gzcat is sometimes installed as zcat.  Be warned that on many
+    (most) UNIX machines, zcat is associated with compress (.Z files).
+
+(3) If you do not have gzip 1.2.4, it is available from numerous sites
+    including this one.  Other sites include prep.ai.mit.edu and
+    gatekeeper.dec.com.
+    
+(4) The GNU archive files included in this distribution are packaged
+    exactly like they are on official GNU ftp sites.  When extracting
+    GNU archives, they will not extract under a rtems-<version> 
+    directory.  They will extract themselves under a directory which
+    is the name and version of the tool in question.  For example,
+    gcc-2.5.8.tgz will extract its contents into the subdirectory 
+    gcc-2.5.8.

+Directory Overview
+==================
+
+This is the top level of the RTEMS directory structure.  The following 
+is a description of the files and directories in this directory:
+
+  INSTALL
+    Rudimentary installation instructions.  For more detailed
+    information please see the Release Notes.  The Postscript 
+    version of this manual can be found in the file
+    c_or_ada/doc/relnotes.tgz.
+
+  LICENSE
+    Required legalese.
+
+  README
+    This file.
+
+  c
+    This directory contains the source code for the C 
+    implementation of RTEMS as well as the test suites, sample 
+    applications, Board Support Packages, Device Drivers, and 
+    support libraries.
+
+  doc
+    This directory contains the PDL for the RTEMS executive.
+
+Ada versus C
+============
+
+There are two implementations of RTEMS in this source tree -- 
+in Ada and in C.  These two implementations are functionally
+and structurally equivalent.  The C implementation follows
+the packaging conventions and hiearchical nature of the Ada 
+implementation.  In addition, a style has been followed which 
+allows one to easily find the corresponding Ada and C 
+implementations.  
+
+File names in C and code placement was carefully designed to insure
+a close mapping to the Ada implementation.  The following file name 
+extensions are used:
+
+   .adb - Ada body
+   .ads - Ada specification
+   .adp - Ada body requiring preprocessing
+   .inc - include file for .adp files
+
+   .c   - C body (non-inlined routines)
+   .inl - C body (inlined routines)
+   .h   - C specification
+
+In the executive source, XYZ.c and XYZ.inl correspond directly to a 
+single XYZ.adb or XYZ.adp file.  A .h file corresponds directly to
+the .ads file.  There are only a handful of .inc files in the 
+Ada source and these are used to insure that the desired simple 
+inline textual expansion is performed.  This avoids scoping and
+calling convention side-effects in carefully constructed tests 
+which usually test context switch behavior.
+
+In addition, in Ada code and data name references are always fully
+qualified as PACKAGE.NAME.  In C, this convention is followed 
+by having the package name as part of the name itself and using a
+capital letter to indicate the presence of a "." level.  So we have
+PACKAGE.NAME in Ada and _Package_Name in C.  The leading "_" in C
+is used to avoid naming conflicts between RTEMS and user variables.
+By using these conventions, one can easily compare the C and Ada
+implementations.
+
+The most noticeable difference between the C and Ada83 code is 
+the inability to easily obtain a "typed pointer" in Ada83.  
+Using the "&" operator in C yields a pointer with a specific type.
+The 'Address attribute is the closest feature in Ada83.  This
+returns a System.Address and this must be coerced via Unchecked_Conversion
+into an access type of the desired type.  It is easy to view 
+System.Address as similar to a "void *" in C, but this is not the case.
+A "void *" can be assigned to any other pointer type without an
+explicit conversion.  
+
+The solution adopted to this problem was to provide two routines for
+each access type in the Ada implementation -- one to convert from
+System.Address to the access type and another to go the opposite
+direction.  This results in code which accomplishes the same thing
+as the corresponding C but it is easier to get lost in the clutter
+of the apparent subprogram invocations than the "less bulky"
+C equivalent.
+
+A related difference is the types which are only in Ada which are used 
+for pointers to arrays.  These types do not exist and are not needed 
+in the C implementation.

+RTEMS was developed by On-Line Applications Research (OAR) under
+contract to the U.S. Army Missile Command.  Other than the
+contributions listed in this document, all code and documentation
+was developed by OAR for the Army.
+
+The RTEMS project would like to thank those who have made
+contributions to the project.  Together we make RTEMS a
+much better product.
+
+The following persons/organizations have made contributions:
+
++ Dr. Mikhail (Misha) Savitski (mms@eiscathq.irf.se) of the EISCAT Scientific
+  Association submitted the BSP and other miscellaneous support for the
+  Motorola MVME162 (M68040LC CPU) VMEbus single board computer.
+
++ Division Inc. of Chapel Hill, NC for sponsoring On-Line Applications
+  Research to port RTEMS to the Hewlett-Packard PA-RISC architecture (V1.1)
+  and the addition of HP-UX as a development host. Tony Bennett
+  (tbennett@divnc.com) was assisted in this effort by Joel Sherrill
+  (jsherril@redstone.army.mil).  Tony also deserves a big pat on the
+  back for contributing significantly to the overall organization
+  of the development environment and directory structure.  RTEMS
+  is much easier to build because of Tony.
+
++ Greg Allen of Division Inc. of Chapel Hill, NC for 
+  porting RTEMS to HP-UX.  This port treats a UNIX computer as simply
+  another RTEMS target processor.  This port can be used to develop 
+  and test code which will ultimately run on the embedded platform.
+
++ Doug McBride (mcbride@rodin.colorado.edu) of the Colorado Space Grant
+  College at the University of Colorado at Boulder submitted the BSP
+  for the Motorola IDP board (M68EC040 CPU) single board computer.  The
+  BSP leverages heavily off of the existing RTEMS BSP framework, the
+  examples in the back of the IDP user's manual, and the libgloss example
+  support for the IDP board from the newlib/libgloss distribution.
+
+Finally, the RTEMS project would like to thank those who have contributed
+to the other free software efforts which RTEMS utilizes.  The primary RTEMS
+development environment is from the Free Software Foundation (the GNU
+project).  The "newlib" C library was put together by Cygnus and is
+a collaboration of the efforts of numerous individuals and organizations.
+
+We would like to see your name here.  BSPs and ports are always welcome.
+Useful libraries which support RTEMS applications are also an important
+part of providing a strong foundation for the development of real-time
+embedded applications and are welcome as submission.

+This is the list of outstanding problems in this release.
+
+1.  The m68000 support is not complete.  Someone with target hardware
+    needs to complete the missing gaps.  Look for ifdef's based on the
+    M68K_* macros defined in c/make/cpu/m68k.cfg.  Most of the code
+    is present but none of it is tested.  An attempt was made to insert
+    "#warnings" preprocessor directives in the appropriate places.
+    So these are a good starting spot.
+
+2.  The only i960 family member tested is the CA.  No support for the
+    floating point support found in other family members is present.
+    This also implies that RTEMS may "think" of something as generic
+    across the i960 family when in fact it is specific to the CA.
+
+3.  The __read() system call in all of the BSPs using single
+    character input/output needs to be smarter.  The following
+    issues need to be addressed:
+
+       + echoing of characters on input
+       + CR/NL echoing
+       + backspaces
+       + tabs
+
+4.  Solaris 2.3 port notes:
+
+       + Some of the tests run correctly when run interactively but
+         the screen and output do not match when the output is 
+         redirected to a file.
+
+       + sometimes a stray SIGALRM is reported as spfatal completes.
+
+5.  Some of the tests may execute correctly and not produce the exact
+    ordering of lines in the screen file.  This appears to be a combination
+    of a number of factors including buffering, processor speed, IO
+    device overhead, and clock interrupt rate.

+ *   Packhex is a hex-file compaction utility.  It attempts to concatenate
+ *   hex records to produce more size-efficient packaging.
+ *
+ *   Limitations: Input files must be correctly formatted.  This utility
+ *                is not robust enough to detect hex-record formatting
+ *                errors.

+ * unhex
+ *      convert a hex file to binary equivalent.  If more than one file name
+ *      is given, then the output will be logically concatenated together.
+ *      stdin and stdout are defaults. Verbose will enable checksum output.
+ *
+ *  Supported input formats are Intel hex, Motorola S records, and TI 'B'
+ *  records.
+ *
+ * Intel hex input format is
+ *      Byte
+ *       1          Colon :
+ *       2..3       Record length, eg: "20"
+ *       4..7       load address nibbles
+ *       8..9       record type: "00" (data) or "02" base addr
+ *       10..x      data bytes in ascii-hex

+Overview of newlib support (newlib is from CYGNUS)
+    Each task can have its own libc state including:
+        open stdio files
+        strtok
+        multi precision arithmetic state
+        etc.
+
+    This is implemented by a reentrancy data structure for each task.
+
+    When a task is "started" (in RTEMS sense) the reentrancy structure
+    is allocated.  Its address is stored in notepad[NOTEPAD_LAST].
+
+    When task is switched to, the value of global variable _impure_ptr
+    is changed to the value of the new tasks reentrancy structure.
+
+    When a task is deleted
+        atexit() processing (for that task) happens
+        task's stdio buffers are flushed
+
+    When exit(3) is called
+        calling task's atexit processing done
+        global libc state atexit processing done
+            (this will include any atexit routines installed by drivers)
+        executive is shutdown
+            causes a context switch back to bsp land
+
+
+NOTE:
+    libc extension are installed by bsp_libc_init()
+        iff we are using clock interrupts.
+        This hack is necessary to allow the tmtests to avoid
+        timing the extensions.
