This is an irc bot written in Java using the PircBotX IRC library. It comes with some basic features (and commands) and can easily be extended with modules. Configuration (per network - yeah, qwoti supports multinetworking) is done in a simple JSON file. Commands can be accepted from both channel and private messages.
Loading and unloading modules happens at runtime using commands on any network the bot is connected to, no need to restart the bot and no interruption in service - only some .java files lying around in the /modules directory and extending the modules super class (AbstractModule).
