There seemed to be agreement that classifiers for the different
implementations was useful.

M-A Lemburg suggested adding versions *as well*. Jean-Paul Calderone and I
thought it was unnecessary as Jython and IronPython are now using CPython
version numbers and different versions of all the implementations tend to
target a specific Python language version - for which we already have

M-A Lemburg disliked the the "Implementation" part of the classifier (he
was only -0 on it though). I think it is useful/necessary to have it to
disambiguate these implementations from other Python-like-languages (like
Cython and Shedskin) that can be used to write Python extensions. (As a
matter of correctness all of these implementations provide "the Python
programming language" and strive very hard indeed not to be distinct
programming languages...)

Nobody else weighed in on that particular topic.

All the best,

Michael Foord
