  NORMAL LOCKS:
 
  Key: <object>
 
  You pass a normal lock if you either are the named object or if you 
  carry the named object.  <object> may be the name or #number of a 
  thing, a playername prefixed by an asterisk (*<playername>), 'me', 
  or 'here'.
 
  Examples:
    > @lock treasure room = secret key
    > @lock private area = me
