[erlang-questions] overriding code in another application
Sat Feb 13 14:50:26 CET 2016
This is more or less what I do, except that each version is compiled as a
separate application. This makes it easy to build with rebar. I suppose
that I don't really have to start those applications, just make the code
available in the code path. Thanks!
