[Catalog-sig] setuptools/distribute/easy_install/pkg_resource sorting algorithm

[M.-A. Lemburg]

I've run into a weird issue with easy_install, that I'm trying to solve:

If I place two files named

egenix_mxodbc_connect_client-2.0.2-py2.6.egg
egenix-mxodbc-connect-client-2.0.2.win32-py2.6.prebuilt.zip

into the same directory and let easy_install running on Linux
scan this, it considers the second file for Windows as best
match.

Is the algorithm used for determining the best match documented
somewhere ?

I've had a look at the implementation, but this left me rather
clueless.

I thought that setuptools would prefer the .egg file over
the prebuilt .zip file - binary files being easier to install
than "source" files.

Thanks,
