 You will need to fetch vendor modules for PHP blocks especially. If you really

+Test against different git versions
+:::::::::::::::::::::::::::::::::::
+
+A script ``test-git-version.sh`` is available in repository to test gitlib against
+many git versions.
+
+This script is not usable on Travis-CI, they would hate me for this. It creates
+a local cache to avoid fetching from Github and compiling if already compiled.
+
+Use it at your own risk, it's still under experiment.
