Hah, sure. In the meantime my way works *now* and with the existing 
tools. :-)

(But only actually true for the way I make it available from pypi - the 
rest of the technique is not "playing games", right?)

Yes, I would prefer to have a single project name with different 
distributions for Python 2 and 3 (and I looked into it) - but with the 
current tools the only way to achieve that is to put both versions into 
a single distribution. This prevents you from versioning them separately 
and is a pain to do anyway if the different versions are in different repos.

The current tools are a real pain for versioning anyway. If your pypi 
page even *links* to a page that offers an alpha or beta (in development 
version) for download then both pip and easy_install will fetch that, in 
preference to the most recent version on pypi. So yes, I agree there is 
room for improvement in the current tools. Hopefully distutils2 will fix 
that. ;-)

All the best,

Michael Foord
