Thanks very much @revolunet !

To clarify: Inria will only maintain this module as a best-effort service, which is coherent with the move to codegouvfr. @EmileRolley is the writer of this module and hence, its natural maintainer, but of course we cannot expect anything from him if he's not paid by Inria or DINUM :) In the absence of an official maintainer, I can still read PRs and approve them, but on a best-effort basis.

Ok, lets try to contribute here ;)
