/*
 * NEW: listen {}
 * OLD: P:Line
 * This defines a port for the ircd to bind to, to
 * allow users/servers to connect to the server.
 * Syntax is as follows:
 * listen (ip number):(port number)
 * {
 *   options {
 *     (options here);
 *   };
 * };
 * or for a plain
 * listen: listen (ip):(port);
 *
 * NOTICE: for ipv6 ips (3ffe:b80:2:51d::2 etc), use listen [ip]:port;
 *
 * That works also.
