/* Rewritten to use the listmode utility by Om, December 2005 */

// The +e channel mode takes a nick!ident@host, glob patterns allowed,
// and if a user matches an entry on the +e list then they can join the channel, overriding any (+b) bans set on them
// Now supports CIDR and IP addresses -- Brain
