Note that at the moment, this is building and testing a "test" repo.
This test repo is not the same one that you use by following our docs.
Once this new code is better tested, we'll switch over (existing users
will not have to do anything to use this new repo).
Even though the overviewer repo is hosted on github, this new CI stuff
is useful for mirrors of overviewer hosted on gitlab.
To support package builds for a few distributions, a set of dockerfiles
have been created.
