If you have a version string that isn't rational (i.e. NormalizedVersion
doesn't like it) then you might be able to get an equivalent (or close)
rational version from this function.
This does a number of simple normalizations to the given string, based
on observation of versions currently in use on PyPI. Given a dump of
those version during PyCon 2009, 4287 of them:
- 2312 (53.93%) match NormalizedVersion without change
with the automatic suggestion
- 3474 (81.04%) match when using this suggestion method
@param s {str} An irrational version string.
@returns A rational version string, or None, if couldn't determine one.
