python3-distutils-extra binary package in Ubuntu Focal amd64

 This package provides additional functions to Python's distutils and
 setuptools. It allows you to easily integrate gettext, icons and GNOME
 documentation into your build and installation process.
 .
 It also provides an "auto" module which provides a "do what I mean" automatic
 build system; if you stick to the conventions, you do not need to write
 setup.cfg, POTFILES.in, or MANIFEST.in, and setup.py just needs to have the
 package metadata (such as project name and version).
