=head1 NAME

Automake::Getopt - GCS conforming parser for command line options

=head1 SYNOPSIS

use Automake::Getopt;

=head1 DESCRIPTION

Export a function C<parse_options>, performing parsing of command
line options in conformance to the GNU Coding standards.

use vars qw (@ISA @EXPORT);
@ISA = qw (Exporter);
@EXPORT= qw/getopt/;

=item C<parse_options (%option)>

Wrapper around C<Getopt::Long>, trying to conform to the GNU
Coding Standards for error messages.
