# Sets GOG_GAME_* variables for use with games that can be obtained from GOG.

|
# Additionally, some games are not available on all platforms. ebuilds are

# allowed to prefer a platform that works best with the host platform.
|
|
# However, GOG probably supplies only x86 binaries for Linux, Mac and Windows.
|
|
# It is up to the ebuild to enable and offer other alternate avenues to support
|
|
# a particular game.
