[Zope] question regarding starting zope 2.7.0 as a non root user

[glams at itcilo.org]

Hi All

I've installed zope 2.7.0 (on SuSe 9.0) and succeeded in configuring 
rewrite rules and virtual host with apache 2
For the time being I'm starting it as root and setuid it as zope (using 
etc/zope.conf) 

I would like to start it directly as zope (I don't need to bind to 
port/1024) but it's not clear to me how to do it. With the previous 
version there was the -u switch that allowed you to specify which user to 
use. I search for some similar option, read the startup script and search 
the web but I'm not able to find it.

Any pointer to some documentation would appreciated

Thanks
