IRC is a protocol for text exchanges with multiple recipients with publish/subscribe capabilities. A basic program that interacts with an IRC server is easy to make, but becomes more difficult with additional functionality. The task involves a few domains: sockets, parsing, and a multi-way mapping object for the state.
