Binary package “chocolate-strife” in ubuntu xenial

Strife engine closely-compatible with Vanilla Strife

 Chocolate Doom aims to accurately reproduce the original DOS version of
 Doom and other games based on the Doom engine in a form that can be
 run on modern computers. Unlike most modern Doom engines, Chocolate Doom
 is not derived from the Boom source port and does not inherit its
 features (or bugs).
 Chocolate Strife is an accurate and complete recreation of Rogue
 Entertainment's "Strife: Quest for the Sigil". It was created through more
 than two years of reverse engineering effort with the blessings of the
 original programmers of the game.
 Chocolate Strife requires game data to play. Commercial game data can be
 packaged using "game-data-packager".
