=head1 DESCRIPTION

Worse is better, baby.

This started at around 12 lines with a couple of regexen, and you could
probably get most of it down to a one-liner without much trouble. I decided to
add a couple of extra options instead.

=head1 BUGS

Are you kidding? I'd be shocked if this worked anywhere besides my laptop.
