You could take the opportunity to rewrite this section to use context
manager to handle the file object:
with open(...) as f

I think it would be best to use autoloadpath and modconfpath for the
automatic creation of such files, but use all known variants of these
paths for the package splitting. If the module makefile creates the
files in one of the places the package splitter should find them without
requireing the customization of the recipe.
