Dm is the `dungeon master', a program that allows you to control when
|
||||
users can play games. (Note that this does not control any private
|
||||
copies of games they may have). I do not claim that this program is
|
||||
actually useful, but it is included in bsd-games since it is in
|
||||
NetBSD.
|
||||
|
||||
Add -DLOG to the DEFS in the Makefile if you want logging of games
|
||||
playing.
