+.Nm dm.conf
+.Nd \&dm configuration file
+.Sh DESCRIPTION
+The
+.Xr dm.conf
+file
+is the configuration file for the
+.Xr \&dm 8
+program.
+It consists of lines beginning with one of three keywords, ``badtty'',
+``game'', and ``time''.  All other lines are ignored.
+.Pp
+Any tty listed after the keyword ``badtty'' may not have games played on
+it.
+Entries consist of two white-space separated fields: the string
+``badtty'' and the ttyname as returned by
+.Xr ttyname 3 .
+For example,
+to keep the uucp dialout, ``tty19'', from being used for games, the
+entry would be:
+.Bd -literal -offset indent
+badtty	/dev/tty19
+.Ed
+.Pp
+Any day/hour combination listed after the keyword ``time'' will disallow
+games during those hours.  Entries consist of four white-space separated
+fields: the string ``time'', the unabbreviated day of the week and the
+beginning and ending time of a period of the day when games may not be
+played.  The time fields are in a 0 based, 24-hour clock.  For example,
+the following entry allows games playing before 8AM and after 5PM on
+Mondays.
+.Bd -literal -offset indent
+time		Monday	8	17
+.Ed
+.Pp
+Any game listed after the keyword ``game'' will set parameters for a specific
+game.  Entries consist of five white-space separated fields: the keyword
+``game'', the name of a game, the highest system load average at which the
+game may be played, the maximum users allowed if the game is to be played,
+and the priority at which the game is to be run.  Any of these fields may
+start with a non-numeric character, resulting in no game limitation or
+priority based on that field.  The game "default" controls the settings for
+any game not otherwise listed, and must be the last ``game'' entry in the
+file.  Priorities may not be negative.  For example, the following entries
+limits the game ``hack'' to running only when the system has 10 or less
+users and a load average of 5 or less; all other games may be run any time
+the system has 15 or less users.
