11/24/2014: I wasn't happy with direction of development towards using an SQLite DB for configuration. The next update will include a new JSON configuration file which can be dynamically modified by the bot's admins over IRC. Still working out some of the kinks & this should prepare for the first stable. Also in the works is the quotes plugin which also includes a PHP class to help you interact with the database outside of the bot (on a website for example).
ClassyBot sure is one classy IRC bot! ClassyBot is built using my IRCBot class available at https://GitHub.com/xnite/PHPIRCBotClass
The current GitHub master repository is for development purposes therefore may contain code that does not function as it should. If you are okay with this, feel free to pull from the current master branch, otherwise please see the stable releases.
