 * Net_SmartIRC
 * This is a PHP class for communication with IRC networks,
 * which conforms to the RFC 2812 (IRC protocol).
 * It's an API that handles all IRC protocol messages.
 * This class is designed for creating IRC bots, chats and show irc related info on webpages.
 *
 * Documenation, a HOWTO and examples are in SmartIRC included.
 *
 * Here you will find a service bot which I am also developing
 * <http://cvs.meebey.net/atbs> and <http://cvs.meebey.net/phpbitch>
 * Latest versions of Net_SmartIRC you will find on the project homepage
 * or get it through PEAR since SmartIRC is an official PEAR package.
 * See <http://pear.php.net/Net_SmartIRC>.
 *
 * Official Project Homepage: <http://sf.net/projects/phpsmartirc>
