Sirs, where do I find the PYTHONPATH env variable? I would like to be able to import povray whose executable code is in /home/xyz/pov/povray-3.5 I was thinking, $ set env PYTHONPATH .:/home/xyz/pov/povray-3.5 would do it. However I don't know where the variable is stored or how to check it before and after. BTW $env does not show the variabe. TIA Re-v
