[erlang-questions] erlang.mk, relx, multiple apps, directory structure

[t x]

Hi,

  Can someone please point me to a git hub repo that:

  1) uses erlang.mk + relx

  2) has multiple apps

  3) is an example of directory structure I should copy?

Thanks!

Problem: I'm starting to need to refactor my code, and I want to know
what an idiomatic multiple-app directory structure looks like.
