This is a plugin for the supybot IRC bot that supports querying Bugzilla installations, showing details about bugs, and reading bugmails sent from Bugzilla to show updates in an IRC channel. It supports working with multiple Bugzilla installations and can work across many channels and networks.
The main bot using this plugin is "bugbot" on irc.mozilla.org and FreeNode IRC (though he is called "buggbot" on FreeNode).
Getting the Plugin
I don't really do releases of the code, but the code is kept in bzr and should always be stable enough to check out and use yourself, like this:
bzr co bzr://bzr.everythingsolved.com/supybot/Bugzilla
Then just place the "Bugzilla" directory in your bot's "plugins" directory, and tell the bot load Bugzilla. You can read the README.txt that comes with the plugin for more details on getting started.
You can update to the latest version or the plugin by changing to the Bugzilla plugin's directory and doing bzr up.
