[Zope-dev] Accessing root object

[Loren Stafford]

I can't figure out the opposite angle on this. In __init__.py, my product
creates a root-level object named 'S' with Martijn's method below. Now
another module 'D'  needs to look up 'S' and get a reference to the object
so it can call one of its methods "S.next". But I don't see how to look up
'S'. I'm sure I'm just being dense. Can somebody help?
