Are you sure you were using mod_python before and not just a CGI script
written in Python? They are different things and you do not need
mod_python to write CGI scripts. In CGI scripts you don't need the
functions as script are executed in total each time. Thus, the fact
you didn't have functions before suggests to me you weren't truly
using mod_python before.

Can you post a small but complete self contained example of what you
were using before.

This code is poorly written. You should NOT assign a "req" object to
a global variable because if you ever upgrade to Apache 2.0 and use
a multithread Apache MPM then multiple requests could be executing in
index() at the same time and they will interfere with each other. You
should pass the "req" object to other functions if they need to access

It should be sufficient to use "propman.py" even if you were to use
mod_python.publisher as it will fallback to calling "index()".

If you have control over this box, I would highly recommend you upgrade
to Apache 2.2 and mod_python 3.2.8.
