#
# This program is a Perl package running on Perl 4.036 or later.
# The package provides routines to process command line options like
# as GNU getopt_long().
#
# Version:
#     2.0.2
#
# Interface:
#
#   &getopt_initialize(LIST)
#     Set a list of command line options and initialize internal data
#     for &getopt_long.
#     You must call the routine before calling &getopt_long.
#     Format of each element in the LIST is:
#
#         `CANONICAL-OPTION-NAME [ALIAS-OPTION-NAME...] ARGUMENT-FLAG'
#
#     CANONICAL-OPTION-NAME, ALIAS-OPTION-NAME and ARGUMENT-FLAG fields
#     are separated by spaces or tabs.
#
#     CANONICAL-OPTION-NAME and ALIAS-OPTION-NAME must be either a single
#     character option including preceding `-' (e.g. `-v'), or a long
#     name option including preceding `--' (e.g. `--version').  Whether
#     CANONICAL-OPTION-NAME is single character option or long name
#     option is not significant.
#
#     ARGUMENT-FLAG must be `no-argument', `required-argument' or 
#     `optional-argument'.  If it is set to `required-argument', the
#     option always takes an argument.  If set to `optional-argument',
#     an argument to the option is optional.
#
#     You can put a special element `+' or `-' at the first element in
#     LIST.  See `Details about Option Processing:' for details.
#     If succeeded to initialize, 1 is returned.  Otherwise 0 is
#     returned.
#
#   &getopt_long
#     Get a option name, and if exists, its argument of the leftmost
#     option in @ARGV.
#
#     An option name and its argument are returned as a list with two
#     elements; the first element is CANONICAL-OPTION-NAME of the option,
#     and second is its argument.
#     Upon return, the option and its argument are removed from @ARGV.
#     When you have already got all options in @ARGV, an empty list is
#     returned.  In this case, only non-option elements are left in
#     @ARGV.
#
#     When an error occurs, an error message is output to standard
#     error, and the option name in a returned list is set to `?'.
#
# Example:
#
#     &getopt_intialize('--help -h no-argument', '--version -v no-argument')
#         || die;
#
#     while (($name, $arg) = &getopt_long) {
#         die "For help, type \`$0 --help\'\n" if ($name eq '?');
#         $opts{$name} = $arg;
#     }
#
# Details about Option Processing:
#
#   * There are three processing modes:
#     1. PERMUTE
#        It permutes the contents of ARGV as it scans, so that all the
#        non-option ARGV-elements are at the end.  This mode is default.
#     2. REQUIRE_ORDER
#        It stops option processing when the first non-option is seen.
#        This mode is chosen if the environment variable POSIXLY_CORRECT
#        is defined, or the first element in the option list is `+'.
#     3. RETURN_IN_ORDER
#        It describes each non-option ARGV-element as if it were the
#        argument of an option with an empty name.
#        This mode is chosen if the first element in the option list is
#        `-'.
#
#   * An argument starting with `-' and not exactly `-', is a single
#     character option.
#     If the option takes an argument, it must be specified at just
#     behind the option name (e.g. `-f/tmp/file'), or at the next
#     ARGV-element of the option name (e.g. `-f /tmp/file').
#     If the option doesn't have an argument, other single character
#     options can be followed within an ARGV-element.  For example,
#     `-l -g -d' is identical to `-lgd'.
#     
#   * An argument starting with `--' and not exactly `--', is a long
#     name option.
#     If the option has an argument, it can be specified at behind the
#     option name preceded by `=' (e.g. `--option=argument'), or at the
#     next ARGV-element of the option name (e.g. `--option argument').
#     Long name options can be abbreviated as long as the abbreviation
#     is unique.
#
#   * The special argument `--' forces an end of option processing.
