[mod_python] How to get mod_python's running version?

Depending on your configuration, the mod_python version number appears
in your server identification string (this is configured by the
ServerTokens directive in httpd.conf).

You can then get mod_python's version number by parsing the
SERVER_SOFTWARE environment variable obtained by :

req.add_common_vars()
req.subprocess_env.get('SERVER_SOFTWARE')

Have a look at the upcoming testhandler which output a bunch of
diagnostic information :

http://svn.apache.org/repos/asf/httpd/mod_python/trunk/lib/python/mod_python/testhandler.py
