path: root/README_Submodules

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