I'm fairly certain you will find that distutils does not support eggs or .egg-info at all. It does write PKG-INFO 1.1. bdist_wheel (a setuptools plugin which does support eggs) has always just upgraded that metadata to version 1.2+ to express setuptools features. Since distutils doesn't support setuptools features you might not need to edit PKG-INFO at all, just generate the manifest (RECORD) correctly. I still think it makes more sense to just download distribute and wheel when you want to build one, but to each his own... if you need to create packages for pypi without being able to install things from it, knock yourself out.
