d2to1 (the ‘d’ is for ‘distutils’) allows using distutils2-like setup.cfg files for a package’s metadata with a distribute/setuptools setup.py script. It works by providing a distutils2-formatted setup.cfg file containing all of a package’s metadata, and a very minimal setup.py which will slurp its arguments from the setup.cfg.

Note: distutils2 has been merged into the CPython standard library, where it is now known as ‘packaging’. This project was started before that change was finalized. So all references to distutils2 should also be assumed to refer to packaging.
