| 2 | +Run findmodulefiles() after running a program with "python -i". The |
| 3 | +resulting file list can be given to mkfrozenresources or to a |
| 4 | +(non-existent) freeze-like application. |
| 5 | +
|
| 6 | +findmodulefiles will create a file listing all modules and where they have |
| 7 | +been imported from. |
| 8 | +
|
| 9 | +findunusedbuiltins takes a list of (modules, file) and prints all builtin modules |
| 10 | +that are _not_ in the list. The list is created by opening the findmodulefiles |
| 11 | +output, reading it and eval()ing that. |
| 12 | +
|
| 13 | +mkpycresource takes a list of (module, file) and creates a resourcefile with all those |
| 14 | +modules and (optionally) a main module. |
