We do this in an ugly, pragmatic way.
Start the system with all modules available, run the test suite, then
Now you have a list of exactly what's needed. I then basically paste
that into a Makefile.
Works well for us because our system is small and test suite is large.
I realise that it won't work in general.
apply(), M:F, spawn() and hot loading make the problem impossible for
"sufficiently nasty" code. Your post has made me wonder how good the
information from xref and dialyzer (which came out after I started
doing this) would be for a real-world system. I'll try it out on ours
and report back.
