|   | """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. | ||
