// Description: This class creates an IRC socket and allows
// The main "script" to interact with any IRC server.
//
// Requirements: a PHP4/PHP5 compiled with --with-sockets.
//
// You are free to use this class whenever and wherever
// you want; however, a small credit (link or something else)
// Are generally accepted :)
