/**
 * OPCommand.cc
 *
 * 20/12/2000 - Greg Sikorski <gte@atomicrevs.demon.co.uk>
 * Initial Version.
 *
 * 28/12/2000 - Greg Sikorski <gte@atomicrevs.demon.co.uk>
 * Added multilingual support.
 *
 * 01/01/2001 - Greg Sikorski <gte@atomicrevs.demon.co.uk>
 * Woo! First change of 2001. :)
 * Added duplicate checking to avoid people doing:
 * /msg e op #coder-com Gte Gte Gte Gte Gte Gte Gte {etc}
 * And flooding the target with notices.
 *
 * 2001-03-21 - Perry Lorier <isomer@coders.net>
 * added 'on chan' to the message
 *
 * OP's one or more users on a channel the user as access on.
