The two major components needed to play Doom are a Doom engine and an IWAD. This dependency is expressed in the Debian package system using the
doom-wad virtual packages. Virtual packages are names which can be "provided" by real packages.
This flexible approach allows for different combinations of engine and IWAD, whilst preventing an engine without a IWAD from being installed.

Doom is a game, and according to the Filesystem Hierarchy Standard, the binaries belong in
/usr/games and the manual pages in section 6. The same applies for doom utilities.
Doom engines and tools should provide a debian menu and file themselves in the Games section. Prboom suggests "Games/Arcade".
The Debian alternatives system (also adopted by Red Hat) allows multiple packages to provide the same files and for the system administrator to choose which package provides the files at a given time.
The doom IWADs are registered with the alternatives system. The canonical locations are:
/usr/share/games/doom/doom1.wad 4 /usr/share/games/doom/doom.wad /usr/share/games/doom/udoom.wad /usr/share/games/doom/doom2.wad /usr/share/games/doom/doom2f.wad /usr/share/games/doom/tnt.wad /usr/share/games/doom/plutonia.wad
Tools (and engines) which require an IWAD should check for the existence of these files.
Id Software IWAD files carry an alternatives priority of 25; the freedoom alternatives use 50. Therefore, the Id IWADs will override the freedoom ones if both are present (unless the system administrator intervenes).
