+ Dealing with incompatible versions of packages. If someone wants to embed a copy of (say) mxDateTime in their own package, the only excuses are that they're afraid of overwriting the user's existing mxDateTime installation (if any), and/or of having some future installation of something else overwrite mxDateTime with an incompatible version. Those are bad problems, but package embedding is no solution. You have a much better approach to that already via the DateTime.__version__ string! "Something like that" needs to be formalized and imposed on all public packages.

Been there, tried that, bought the flame war. I made the mistake of kicking off the Distutils SIG back in Decemver with a proposal for a standard version numbering scheme for Python module distributions. See http://www.python.org/pipermail/distutils-sig/1998-December/000016.html for the kick-off of that "heated discussion". ;-) FWIW, if I was posting that message today, I would s/must/should/ and that's about it. And I would stress that these are "Proposed Recommended Guidelines" rather than "Things You Must Do or Distutils Will Slam the Door in Your Face", which is what it must have sounded like based on some of the responses. Folks: please don't reheat this flamewar on python-dev -- if you're interested in it, it will undoubtedly come up again on distutils-sig in due course!
