+.B /usr/games/zork
+.SH DESCRIPTION
+.I Dungeon
+is a computer fantasy simulation based on Adventure and on
+Dungeons & Dragons, originally written by Lebling, Blank,
+and Anderson of MIT.
+In it you explore a dungeon made up of
+various rooms, caves, rivers, and so on.
+The object of the game is to collect as much treasure as possible
+and stow it safely in the trophy case (and, of course, to stay alive.)
+.PP
+Figuring out the rules is part of the game, but if you are stuck,
+you should start off with \*(lqopen mailbox\*(rq, \*(lqtake leaflet\*(rq, and then
+\*(lqread leaflet\*(rq.
+Additional useful commands that are not documented include:
+.PP
+quit (to end the game)
+.PP
+!cmd (the usual shell escape convention)
+.PP

+.SH BUGS
+We don't have the source, only a pdp-11 binary that has been severely
+munged to get it to work on V7 Unix.
+(The original binary was for RSX-11, which was patched for V6,
+and then patched for V7.)
