[Distutils] on storing vcs version infos in sdists

hi,

whats a good place to store version information from a vcs in a sdist, without needing to drop them into python files.

i wrote a simple module that gets me version meta-data from hg repos/archives, using the same algorithms hg is using for its own version number generation.

The nit in that is that i have to store it in a python file. I'd much rather put it somewhere else in case of sdists, but i have no idea where/how i should put it to fit with the setuptools/distribute standards.
