Yup, that sounds better.

Actually,  both of these directories have historically worked in much
the same way as the Products package does.

A software home may have (actually currently must have) an "import"
directory.  Zope currently slurps various TTW "examples" from a zexp
file in the software home import directory.  I'd really like to dump
this dependency, but it would take a bit of work.

The Extensions directory... errr.. this should probably not be in a
software home anymore.  I can't think of anything that would break were
it to not be there anymore (besides products that depend on the physical
layout of the software home, which shouldn't exist).

Personally, I think we should just hardcode '/home/fred/zope/import'
into the core as the import directory and be done with it. ;-)
