 * Asynchronous: IRC is an asynchronous protocol and so should be a library that implements it. Coroutines are used to process events from the server asynchronously.
 * Modularised and extensible: Features on top of RFC1459 are implemented as separate modules for a user to pick and choose, and write their own. Broad features are written to be as extensible as possible.
 * Liberally licensed: The 3-clause BSD license ensures you can use it everywhere.
