Bug#775082: game-data-packager: move quake, quake2 to Python/YAML

[Simon McVittie]

Package: game-data-packager
Version: 39
Severity: wishlist
Control: block -1 by 775078 775079

I think my experiment with declarative game data has been a success
and I would like to use it for all the games. quake and quake2 need
a couple more features first, though.

Ideally, I would also like q2rogue and q2xatrix to become part of
quake2, but that requires either uploading Yamagi's game-code modules
to non-free (preferred, if the license is distributable, because they're
source code that we can patch) or doing a lot of custom code in
lib/game_data_packager/games/quake2.py.
