[gentoo-portage-dev] [PATCH] test_compile_modules: skip files that require newer Python version

[Michał Górny]

Support skipping Python modules and scripts that require newer Python
version than currently used during compile tests. Add a metadata db that
can be used to store additional information about Python files, and
store the required language version there.
