"""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.
