This is the Shareware doom-wad file for Doom. A doom-wad file is required for doom-engines such as prboom or chocolate-doom. You can use this package to sample the commercial game in conjunction with a package providing doom-engine.
If you own one of the commercial Doom games, you can use game-data-packager to register your commercial doom-wad file on your Debian system.
Finally, you can use the freedoom boom-wad package in conjunction with a boom-engine (e.g. prboom).
