--- Comment #4 from Michael Cronenworth mike@cchtml.com --- I'm not saying you are required to use the stable release, but I would recommend it if you are going to include this game in stable Fedora releases.
In any case, what we need is the git commit hash, or the checkout date, to reliably get the same source tarball that you created.
