BTW, for determining name of template you should use something
like:

   import os
   template = os.path.splitext(__file__)[0] + '.template'

   from mod_python import apache, psp
   def handler(req):
       req.content_type = 'text/html'
       tmpl = psp.PSP(req, filename=template)
       tmpl.run(vars = {'greet': 'world'})
       return " "

Accept that you may have put "./hello.template" for illustrative
purposes only, but thought I would mention this anyway so no one
else is confused when looking at this in the mailing list archive.
