1 To add a submodule "mirrored" from gitolite:
2 - It must be accessible from anywhere without authentication (in .gitmodules) ->
3 git://git.immae.eu/github/*
4 - But it should be accessible via gitolite:github/* in the "work" dir, since
5 otherwise it would never be refreshed by gitolite (.git/modules/modules/*/config)
