[erlang-questions] [ANN] erlang.mk build tool

Well I'm sure if you create a base Makefile (without erlang.mk) that 
exports DEPS_DIR and then call $(MAKE) on all folders in /apps (which 
would themselves contain Makefiles that use erlang.mk), it would work 
just fine. You can still keep only one erlang.mk in your repos and use 
include ../../erlang.mk instead for example.

But know that this folder structure is a rebar thing and not standard 
(just like /deps you'll say, but that one is insanely useful regardless 
of the project structure otherwise).
