  +dir <location>
  
  The turbolift (and rooms outside the turbolift) are 'directory rooms'. An
  IC directory is posted at each location. Appropriate location fields are
  [pretty(u(#420/FIELDS))].
  
  This directory gives a list of 'player owned rooms', IE, housing and shops.
  Please note that it does /not/ list empty or unowned shops.
