-- description:
--
-- This package is an Ada implementation of getopt() as specified by the
-- document "The Single UNIX Specification, Version 2", Copyright 1997 The
-- Open Group
--
-- This describes the items involveed using example
--
--
-- curopt
-- |
-- V
-- "-f foo -dbc -k"
-- ^
-- |
-- optind
--
-- optind is position (index) that tells which command line argument is
-- being processed now.
-- curopt tells which optchar is being processed within one command line
-- argument. This is needed only if more that one optchar are stuck
-- togother in one argument with no space, as in -df where both d and f
-- are valid optchar and d takes no optarg.
--
-- Compiler used: GCC 4.5.2 targeting i386-rtems4.10
-- Platform: Fedora 14/x86_64
