Isn't a better approach to abstract out the fixed file refs and pass
in docroot as a reference?

  def handler(http):
     docroot = http.document_root()
     do_some_call(docroot)
     .
     .
     .

Then you can set docroot in the apache config, eg:

  <VirtualHost *>
        ServerName rssagg.tapsellferrier.co.uk
        DocumentRoot /home/nferrier/projects/rssagg
        CustomLog /var/log/apache2/access.log tf_combined

        PythonPath "sys.path+['/home/nferrier/projects/rssagg']"
        PythonDebug On
        PythonEnablePdb Off

        .
        .
        .

  </VirtualHost>


Anyway, that's what I do.
