ozBot is a general-purpose IRC bot with lots of addon modules. It ships with a module for Bugzilla that lets you perform queries against your Bugzilla and also can announce bug changes. On irc.mozilla.org
we no longer use bzbo
t, because this module can do most of what he used to do, but if all you want is bug change announcements, MozBot? might be overkill. Note: The tarballs of MozBot? on the FTP server as of this writing are VERY outdated, and do not contain a working Bugzilla module. You must check MozBot? out of the Mozilla CVS repository to get a working Bugzilla module.
