NetHack
     
         /net'hak/ (Unix) A dungeon game similar to {rogue} but
        more elaborate, distributed in {C} source over {Usenet} and
        very popular at {Unix} sites and on {PC}-class machines
        (nethack is probably the most widely distributed of the
        {freeware} dungeon games).  The earliest versions, written by
        Jay Fenlason and later considerably enhanced by Andries
        Brouwer, were simply called "hack".  The name changed when
        maintenance was taken over by a group of hackers originally
        organised by Mike Stephenson.
     
        Version: NetHack 3.2 (Apr 1996?).
