I liked Mark Pilgrim's _Dive into Python_.  I don't remember if it goes
into details about how Python modules work.

Yes, but only if you could make sure that your package or module was
imported during Zope 3 startup.

Grok uses a similar scheme, as far as I understand: you declare your
adapters and utilites in Python code, and then a single ZCML directive
in the grok: namespace loads your package and registers everything.

Does Grok have a website?  Google doesn't give me anything more useful
than these blog posts:
