I'm working on a little add-on to Wakaba that needs to peek into Wakaba's databases and count how many posts were made by a certain user. Any chance anyone who groks Perl could explain how Wakaba encodes tripcodes? (Pseudocode would work.) I'm a PHP nerd; Perl baffles me. I see "sub process_tripcode" on line 572, but I can't understand what it's doing.

TIA.
