[Zope] how i can make zope run on the startup

hi guys, am usring redhat 7.2, each time i want to start zope i have to chmod o+t then run start script. how can i make Zope to run at the system startup? btw, i got ActivePython 2.1.3, then i install it through rpm, but when i type python -v, it gives me the old python, so i had to go to the zope bin directory each time i want the script of *.py to run correctly, any idea? thx v.much in advance -- Hytham Shehab
