It looks like Robert has beaten me to the punch on this email, too, but
just to throw a little water of my own on the fire, setuptools and
python eggs are controversial in some circles. (Not just ez_setup.py
that Robert pointed out.) Although I agree with you that they seem to
offer many really nice things, there have been recent raging discussions
on distutils-sig and debian-python.
One serious issue with eggs is that they are a package system outside
the control/knowledge of package managers such as debian's apt-get.
Since debian figured out package management a long time ago, and since
setuptools evolved independently of debian, largely for use outside of
debian, it's understandable that setuptools offers partially overlapping
and also portions of distinctly non-debian behavior. And it's also
understandable, but possibly avoidable and IMO definitely regrettable,
that some debian developers are actively and even vehemently resisting
I think eggs are great for, among other things, maintaining a personal
(non-root) cache of python packages in your personal directory, even in
a debian system. Also, since they do dependency checking of Python
packages based on what's in the packages, it means your Python
development can be with bleeding-edge stuff but still under the control
of a package manager.
And then there are OSs without package managers whatsoever, where I
suspect people may be even more enthusiastic... (At least I think they
