Thanks for the positive feedback. Fred Drake worked very hard on this. One thing we did right was to leverage distutils ability to build binary releases. I'm also encouraged by work done at the recent PyCon sprints that someday we'll even have a packaging system, for Python that will allow us to make installation of packages much easier too.
FWIW, my original reason for trying Gentoo Linux was to evaluate its packaging system, Portage, which is written in Python. I intended to grab ideas and incorporate them into a new packaging system, but Portage turned out to be so good that I switched to Gentoo and stopped designing my own system. Portage also leverages distutils and can produce/consume binary packages.
Have you thought about porting Portage, or something like it, for use as a general Python package management system?
BTW, I'll give you an escape hatch. ;-) Portage is licensed under the GPL, which probably excludes it from the Python standard library.
Too bad. It's possible that is surmountable somehow.
I'm sure Fred is doing excellent work, but I'm having trouble seeing why
we need zpkgtools. Is it not sufficient to just "python setup.py
install" all of Zope 3?
I hope so. What zpkgtools does is to:
- Build our setup.py script (which we name install.py) for us based on meta data. In that sense, it is a setup.py-development tool.
- Allow us more flexibility in deciding what a release is by allowing us to specify what to include in a release and make sure other things are included to make sure we distribute what we need.
Also, by providing dependincies as meta-data files, we:
- We are making design-level commitments about interdependencies, and
- We are taking a step towards being able to have an automated package system that will someday allow releases and updates to be smaller, more automated, and easier to keep up to date.

checkouts and Twisted, even though I actually use less than 10% of the code installed. In fact, my co-workers are about to put such a system into production. The unused code causes no problems that I've detected.
Note that we plan to make the checkout setup.py zpkgtools-based evenually, so we don't have to maintain it.
I want to be very selective about what we put in a release. I only want to release packages that we are willing to provide support for. There are lots of packages in the repository that we haven't made such a commitment for. zpkgtools gives us the ability to control what we include.
