Yes? And then you draw some sort of conclusion of this that totally escapes me. >> Why do I need setup.py? > > To define the core entry points, basically.

OK.

They won't work.

But I've also pointed out that I don't understand why they would be needed. For all other packages it's recommended that only source distributions are done unless you have c-extensions. Why is setuptools an exception? > or SVN-based manifest building (for making sdists). Well, we can survive without that, as far as I can see. -- Lennart Regebro: Python, Zope, Plone, Grok http://regebro.wordpress.com/ +33 661 58 14 64 _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
