NAME
    Getopt::Long::Util - Utilities for Getopt::Long

VERSION
    This document describes version 0.78 of Getopt::Long::Util (from Perl
    distribution Getopt-Long-Util), released on 2014-12-09.

FUNCTIONS
  parse_getopt_long_opt_spec($str) => hash
    Parse Getopt::Long option specification. Will produce a hash with some
    keys: "opts" (array of option names, in the order specified in the opt
    spec), "type" (string, type name), "desttype" (either '', or '@' or
    '%'), "is_neg" (true for "--opt!"), "is_inc" (true for "--opt+"),
    "min_vals" (int, usually 0 or 1), "max_vals" (int, usually 0 or 1 except
    for option that requires multiple values),

    Will return undef if it can't parse $str.

    Examples:

     $res = parse_getopt_long_opt_spec('help|h|?'); # {opts=>['help', 'h', '?'], type=>undef}
     $res = parse_getopt_long_opt_spec('--foo=s');  # {opts=>['foo'], type=>'s', min_vals=>1, max_vals=>1}

  humanize_getopt_long_opt_spec($str) => str
    Convert Getopt::Long option specification like "help|h|?" or <--foo=s>
    or "debug!" into, respectively, "--help, -h, -?" or "--foo=s" or
    "--(no)debug". Will die if can't parse $str. The output is suitable for
    including in help/usage text.

SEE ALSO
    Getopt::Long

    Getopt::Long::Spec, which can also parse Getopt::Long spec into hash as
    well as transform back the hash to Getopt::Long spec. OO interface. I
    should've found this module first before writing my own
    "parse_getopt_long_opt_spec()". But at least currently
    "parse_getopt_long_opt_spec()" is at least about 30-100+% faster than
    Getopt::Long::Spec::Parser, has a much simpler implementation (a single
    regex match), and can handle valid Getopt::Long specs that
    Getopt::Long::Spec::Parser fails to parse, e.g. "foo|f=s@".
