I’m sure there must be an easy and/or idiomatic way to do this, but I haven’t managed to find it.

If I have an umbrella application with several applications inside it, is it possible to define an overall version number somewhere and have it picked up by the individual apps, the umbrella app (now that exdoc seems to require a version for that too) and by distillery for releases? I’m currently having to bump versions in three separate mix.exs files, plus rel/config.exs, every time I want to make a release, which is tedious and error prone.

I think I can use set version: current_version(:some_app_name) to configure the release version, so that’s one off the list, but any hints to combine the individual app versions would be appreciated.
