Mozbot is an Perl IRC bot developed by the Mozilla Project. I had been in the market for a modular Perl IRC bot for a while, since people wanted a lot out of foxxbot, and I could only provide so much in the old architecture.
There has been some good and some bad. I've had to tighten up the syntax a lot, since the old foxxbot would better handle input that was somewhat ambiguous. This has caused some problems, and made the 'production' version of foxxbot's rolling code much more ambiguous that I'd like it to be. Oh well, got to please the masses.
I ported the old foxxbot's dice rolling code to MozBot, and have it posted here. And I plan to continue posting modules I write to that location. If you feel inclined, please feel free to mail me a patch.
