The spec file for each per-module package I just created is generated through a little and nasty script which converts spec files generated by setuptools to ones complying with Fedora standards. (The script is too nasty to open its source.) A better solution is to hack setuptools, and/or distutils, itself to generate standard-complying spec files directly. But this may take some time.
I've attached a script called zopespec. zopespec works similarly to (and probably could be merged with) rpmdev-newspec. You run it and give it a package name. This can be zope.copy, zope-copy or zope-copy.spec.
Given the name "zope-copy", zopespec looks up the latest version from pypi.python.org, downloads it and extracts a bunch of metadata. This metadata gets substituted into the spec that is created. It should be generally speaking functional, but of course the generated spec needs to be reviewed by a human. Let me know if you have any thoughts.
