"""Findmodulefiles - Find out where modules are loaded from.
Run findmodulefiles() after running a program with "python -i". The
resulting file list can be given to mkfrozenresources or to a
(non-existent) freeze-like application.
findmodulefiles will create a file listing all modules and where they have
been imported from.
findunusedbuiltins takes a list of (modules, file) and prints all builtin modules
that are _not_ in the list. The list is created by opening the findmodulefiles
output, reading it and eval()ing that.
mkpycresource takes a list of (module, file) and creates a resourcefile with all those
modules and (optionally) a main module.
