Source code is located in "files" section of SF in form of tarballs.
    No VCS is used. The actual repo is dummy and not required at all (F-Droid buildserver
    still requires some repo, though). The source code is split into two parts, the
    library tarball and the game tarball. Each one is downloaded and their checksums
    are compared. The build process should not change across new versions and the
    build section can be copied over, with updated links to library and wesnoth tarballs
    as well their checksums (first four lines in init section). The wesnoth tarball
    contains prebuilt libs, but we're removing them and building again from source.
