I don't know what's out there for Python, but that reminds me a bit
of the Erlang tool "rebar": https://github.com/rebar/rebar

I half remember that there was a later alternative to rebar that had
similarities and maybe improvements.  

Anyway, these might be worth looking at if you're thinking of developing
a Python tool.
