Shaun was kind enough to provide a Perl version of the code, which was good, since I'd have been hard-pressed to come up with one. It's a short piece of code, shorter than the AWK version, so it seemed like it ought to be fairly easy to pick it apart. In the end, I'm not sure I'd call it easy, but it was interesting, and I thought other non-Perl programmers might find it interesting too.
