[Zope] System rc Script

[Ben Ocean]

Hi;
I'd like to install Jim Cain's system rc script 
http://www.zope.org/Members/jec/startstop_howto_html but I crashed my MTA 
by screwing something up. I'm hoping someone out there can help me with a 
few config questions specific to this program:

**In the zope script...
What do these numbers represent?
    chkconfig: 345 90 10

I have a file called *zope.conf* but not in the /etc/ directory. I assume I 
just change the path and that it's the same file, correct?
    /etc/zope.conf

**In the zstart/zstop script...
What is this file? I have no such file.
    ZOPE_BASE=/opt/Zope

I don't have this file. Do I change the path to something else?
    INSTANCE_BASE=/home/httpd/zope

What IS this???
    PS="ps wax"

Since I have 2 pythons, should I change this to python2.1 to conform with 
the latest Zope distro?
    PYTHON=/usr/local/bin/python

**In the env script...
I have no user *www* Should I use root?
    ZOPE_USER=www

I don't have such a file in this path. What should I do?
    ZOPE_BASE=/usr/local/Zope

**In the instances script...
What do these numbers mean?
    zope0 8022 2 0
    site3 8023 2 1

Thanks for any help,
BenO
