Here you're re-introducing '<', '>', '<=' and '>=' while you said [0]
that you where going to drop them.  I'm still not convinced of
allowing this between strings as it will likely lead to mistakes when
comparing "versions".  I'm still tempted by making "python_version" a
RationalVersion() so that you can use '<', '>', '<=' and '>=' safely,
not really convinced of writing something like:

  [setup:python_version == '2.2' or python_version == '2.3' or
   python_version == '2.4']

(Can you even split section headers over multiple lines in ini-files?)


As an asside, python 3 is dropping '<>' so maybe it would be
easier/less confusing to just not include it here?
