##     @lock - limit use of objects

##     Usage:
##       @lock[/switch] <obj> [:type] [= <key>[,key2,key3,...]]    

##     Switches:
##       add    - add a lock (default) from object 
##       del    - remove a lock from object  
##       list   - view all locks on object (default)
##     type:
##       DefaultLock  - the default lock type (default)
##       UseLock      - prevents usage of objects' commands
##       EnterLock    - blocking objects from entering the object
      
##     Locks an object for everyone except those matching the keys.
##     The keys can be of the following types (and searched in this order):
##        - a user #dbref (#2, #45 etc)
##        - a Group name (Builder, Immortal etc, case sensitive)
##        - a Permission string (genperms.get, etc)
##        - a Function():return_value pair. (ex: alliance():Red). The
##            function() is called on the locked object (if it exists) and
##            if its return value matches the Key is passed. If no
##            return_value is given, matches against True.
##        - an Attribute:return_value pair (ex: key:yellow_key). The
##            Attribute is the name of an attribute defined on the locked
##            object. If this attribute has a value matching return_value,
##            the lock is passed. If no return_value is given, 
##            attributes will be searched, requiring a True
##            value.
        
##     If no keys at all are given, the object is locked for everyone.
##     When the lock blocks a user, you may customize which error is given by
##     storing error messages in an attribute. For DefaultLocks, UseLocks and
##     EnterLocks, these attributes are called lock_msg, use_lock_msg and
##     enter_lock_msg respectively.

##                                    its destination.
##                    Rooms:          controls whether the player sees a failure
##                                    message after the room description when
##                                    looking at the room.
##                    Players/Things: controls who may 'get' the object.

##      UseLock:      All but Exits:  controls who may use commands defined on
##                                    the locked object.

##      EnterLock:    Players/Things: controls who may enter/teleport into
##                                    the object.      
##      VisibleLock:  Players/Things: controls if the object is visible to
##                                    someone using the look command.

##     Fail messages echoed to the player are stored in the attributes 'lock_msg',
##     'use_lock_msg', 'enter_lock_msg' and 'visible_lock_msg' on the locked object
##     in question. If no such message is stored, a default will be used (or none at
