Owner-Groups exist to allow players to share control of
   areas and/or objects.

Owner-Groups are made by taking a normal Group and CHOWNing something to it.
   (The owner-group will become STICKY automatically)

The members of an owner-group control EVERYTHING the group owns.
LOCK your owner-group so only the players you trust can use it!

An owner-group must be LINK_OK if you want to give its members
   permission to CHOWN more items to it.

Owner-Groups can NOT be recycled.

To change an owner-group back into a normal group, you must:
    @TOAD it, specifing a player to inherit all of its possessions, or,
    @PURGE it, which recycles everything it owns.
