-=head1 NAME
-
-MooseX::Getopt::Basic - role to implement the basic functionality of
-L<MooseX::Getopt> without GLD.
-
=head1 SYNOPSIS
## In your class
This is like L<MooseX::Getopt> and can be used instead except that it
doesn't make use of L<Getopt::Long::Descriptive> (or "GLD" for short).
-=head1 METHODS

-=item B<new_with_options>
+=method new_with_options
-See L<MooseX::Getopt> .
+See L<MooseX::Getopt/new_with_options>.
-=item B<meta>
+=method process_argv
-This returns the role meta object.
