=head2 -bar, --foo - do a foo

This is the help for --foo, or -bar as the occasion demands

=head2 --tar - do a tar

This is the help for --tar

=head2 --foobar - do a foobar

This is the help for --foobar, which won't be executed
because of the '--' in the command line

=head2 --nosubs -- bump a counter

Nosub has -- supprise -- no associated sub
