 * Name        : ns_ghost_id
 * Author      : Viper  <Viper@Absurd-IRC.net>
 * Date        : 25/05/2008
 * Last update : 25/05/2008
 * Version     : 1.0
 * -----------------------------------------------------------------------------
 * Tested      : Anope-1.7.21 + UnrealIRCd 3.2.6
 * -----------------------------------------------------------------------------
 * This module adds extra functionality to the NickServ GHOST command so that
 * if someone executes a ghost with password and is not already identified for
 * a nick, NickServ will automatically recognize him as owner of the ghosted
 * nickname after changing nick.
 *
 * Note that this will only work on networks with NSNickTracking enabled in the
 * services.conf!
 *
 * This module is published under GPLv2.
 * -----------------------------------------------------------------------------

 * Changelog:
 *
 *    1.0    Initial Release
