I strongly recommend that you separate out the parser into its own, reusable module, if you expect other people to pick it up. The fact that it's entwined monolithically with other junk (like a hand-rolled CGI handler) is going to be a major stumbling block for many people who might otherwise be interested in it.

If you need help modularizing your code, there's some tutorials on the topic here at PerlMonks; and of course you can always ask in the CB or post a SOPW.
