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.

This package provides d2to1 on the Python 2 module path. It is complemented by python3-d2to1.
