+.SH NAME
+rogue \- Exploring The Dungeons of Doom
+.SH SYNOPSIS
+.B @PROGRAM@
+[ -s ]
+[
+.I save_file
+]
+[ -n
+.I playername
+]
+.SH DESCRIPTION
+.PP
+.I Rogue
+is a computer fantasy game with a new twist.  It is crt oriented and the
+object of the game is to survive the attacks of various monsters and get
+a lot of gold, rather than the puzzle solving orientation of most computer
+fantasy games.
+.PP
+To get started you really only need to know two commands.  The command
+.B ?
+will give you a list of the available commands and the command
+.B /
+will identify the things you see on the screen.
+.PP
+To win the game (as opposed to merely playing to beat other people's high
+scores) you must locate the Amulet of Yendor which is somewhere below
+the 20th level of the dungeon and get it out.  Nobody has achieved this
+yet and if somebody does, they will probably go down in history as a hero
+among heros.
+.PP
+When the game ends, either by your death, when you quit, or if you (by
+some miracle) manage to win,
+.I rogue
+will give you a list of the top-ten scorers.  The scoring is based entirely
+upon how much gold you get.  There is a 10% penalty for getting yourself
+killed.
+.PP
+For more detailed directions, read the document
+.I "A Guide to the Dungeons of Doom."
+.SH OPTIONS
+.PP
+If a
+.I save_file
+argument is given,
+.I rogue
+will attempt to load a previously saved game from that file.
+.PP
+With the
+.B -n
+option,
+.I rogue
+will load a game with the name
+.I playername
+from a location defined at compile time.  If no such game exists, it will 
+start one.
+.PP
+The
+.B -s
+option prints the top-ten scores list and exits.

+even after you eat food and sometimes you get a monster on the screen in
+reverse video which may or may not cause a core dump.
