Easiest way to display a pdf, ps or dvi file from python in linux.

Question

I have created an application with python and wxpython.

I would like to display a help file in pdf, ps or dvi format in GNU/Linux.

Could use the distribution pdf viewer, but not so easy when you don't know which they have.

Any ideas on how to solve this?
