French help text

[brouberol]

For now, it's tedious to learn the marcel command, as the marcel --aide output is the one generated by docker --help. To be fully useful, we need to have a translated output (at least for the commands).

We need to modify internal docker if we want to track its release, so this should be upstreamed rather than hardcoding informations that will be outdated in two months

We managed to make them integrate french names into the container name generation, but I don't see them adding random stuff in critical parts such as the help dialog anytime soon :/

I suggest having a function that will parse the docker [command] --help and replace any --flag by the expression --flag / --translated-flag. It should use the translations that are already defined, and thus should not require any complex maintenance.

Well, why not just set the locale for docker then and sed the output of it (s/[d|D]ocker/Marcel/g)?
