DESCRIPTION

       Many  open-source games require game data which is licensed incompatibly with the Debian Free Software Guidelines.  game-data-packager is a
       tool designed to help you locally assemble Debian packages containing such game data from CD-ROMs, the Internet or elsewhere.

OPTIONS

       -i     attempt to install the generated Debian package via dpkg(1) and su(1)

       -d out-directory
	      writes the generated Debian package to the specified directory.

       -n     Do not attempt to install the generated Debian package. This option must be used in conjunction with -d.

       game   The game being packaged. Running game-data-packager without arguments will display a list of valid games. Running game-data-packager
	      with just the game and no further arguments will display a list of valid options for that game.

NAME

     dm -- dungeon master

SYNOPSIS

     ln -s dm game

DESCRIPTION

     dm is a program used to regulate game playing.  dm expects to be invoked with the name of a game that a user wishes to play.  This is done by
     creating symbolic links to dm, in the directory /usr/games for all of the regulated games.  The actual binaries for these games should be
     placed in a ``hidden'' directory, /usr/lib/games/dm, that may only be accessed by the dm program.	dm determines if the requested game is
     available and, if so, runs it.  The file /etc/dm.conf controls the conditions under which games may be run.

     The file /etc/nogames may be used to ``turn off'' game playing.  If the file exists, no game playing is allowed; the contents of the file
     will be displayed to any user requesting a game.

FILES

     /etc/dm.conf	   configuration file
     /etc/nogames	   turns off game playing
     /usr/lib/games/dm	   directory of ``real'' binaries
     /var/games/games.log  game logging file

SEE ALSO

     dm.conf(5)

HISTORY

     The dm command appeared in 4.3BSD-Tahoe.

SECURITY CONSIDERATIONS

     Two issues result from dm running the games setgid ``games''.  First, all games that allow users to run UNIX commands should carefully set
     both the real and effective group ids immediately before executing those commands.  Probably more important is that dm never be setgid any-
     thing but ``games'' so that compromising a game will result only in the user's ability to play games at will.  Secondly, games which previ-
     ously had no reason to run setgid and which accessed user files may have to be modified.
