Currently we freeze the 3 main import-related modules, as well as one module for testing.  Adding more modules or otherwise making any adjustments requires manually editing several files (frozen.c, Makefile.pre.in, ...).  Those files aren't particularly obvious and it's easy to miss one.  So it would be helpful to have a tool that generates the necessary lines in the relevant files, to avoid manual editing.

I'll be putting up a PR shortly.

bpo-45019: Add a tool to generate list of modules to include for frozen modules (gh-27980)
https://github.com/python/cpython/commit/044e8d866fdde3804bdb2282c7d23a8074de8f6f

Is this ready to close?

I'm just waiting for the buildbots to finish.

The PR 28319 seems to have introduced a new deprecation warning in tests :

I'll fix that.

If a directory is renamed anyway, maybe `deepfrozen_modules` is better? `deepfreeze_modules` looks like "modules that are part of deepfreeze tool itself". Also it rhymes with `frozen_modules`.
