Sorry, putting the code up slipped my mind. The code is now on the perlmonk site. (At http://theorbtwo.perlmonk.org/perlmonkscb/perlmonkscb.txt, to be exact, but it's linked to from index.html. The code is very ugly, but it does mostly work. I'll probably be rewriting it almost completly in the nearish future.)
Update: Fixed URL.
