Comment:
The .tar.xz includes all dependencies, which I probably used as a workaround to some git pulls during build failing because of deleted branches and the like.

It also sounded nice not having to hit the Internet after fetching the tarball, but that was never the case since some crates were brokenly outdated from the start.
