[Zope] Is HTTP_MANAGE EnvVar only in Plone? and -w mapping

[Michael Dexter]

I partially figured it out (trying to reduce Plone down to Zope), it 
seems HTTP_MANAGE plays a trick with the accessRule.py External 
Method to set the Plone default location, which I am trying to 
cleanly nuke.

That said, if using -w to have Zope listen on multiple ports, does 
each port get "mapped" to a location/URL in Zope/ZODB?

Thanks,

Michael.
