GOZERBOT is a channel bot that aids conversation in IRC channels and Jabber conference rooms. It's mainly used to serve RSS feeds and to have custom commands made for the channel. More then just a channel bot, GOZERBOT aims to provide a platform for the user to program his own bot and make it into something useful. This is done with a plugin structure that makes it easy to program your own. There are over 100 plugins already written and ready for use.
