While I agree with Phillip on this one, I do know what you're saying.
I've wondered that about some of the packages I'm putting into eggs.

I'm pretty certain this situation will arise where a project
maintainer won't go for a setuptools dependency. Here's one way to
deal with it:

Let's say the project's code is in the package:


What if you toss pkg_resources into pythonfoobar. Then, in all of the
modules you touch, you just do:

from pythonfoobar import pkg_resources

Then, once the package maintainer comes to his or her senses and
realizes that the world is A Better Place With Eggs (tm), there are
two simple ways to introduce the setuptools dependency:

1) project wide search and replace
2) in pythonfoobar/__init__ just import pkg_resources  (this is
assuming you're not using the fancy setuptools namespaces... not many
projects need that, though.)

Ideally, people will go along with setuptools. But, at least this
workaround won't break people's systems.
