* 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 Projet Homepage: <http://sf.net/projects/phpsmartirc>
*
* Net_SmartIRC conforms to RFC 2812 (Internet Relay Chat: Client Protocol)
