What if setuptools isn't installed?

Question

I'm just learning the art of writing a setup.py file for my project. I see there's lots of talk about setuptools, which is supposed to be superior to distutils. There's one thing though that I fail to understand, and I didn't see it addressed in any tutorial I've read about this: What if setuptools isn't installed? I understand it's not part of the standard library, so how can you assume the person who wants to install your program will have it installed?

Answer 1

The standard way to distribute packages with setuptools includes an ez_setup.py script which will automatically download and install setuptools itself - on Windows I believe it will actually install an executable for easy_install. You can get this from the standard setuptools/easy_install distribution.
