IRC Markamp;#39;s IRC API Library 一个php编写的IRC API库

<?php
/**
 * Mark's IRC API Library
 * 
 * Formats data for sending to an IRC network. This library does not handle
 * actual connecting to the IRC server or parsing the IRC servers output.
 * 
 * The raw_send method can be used to send data to the IRC in formats that are
 * either not standard, or not yet implemented here. I know there is a lot more
 * to implement, and I plan to do so as time goes on.
