I volunteer to help with this, but I am not sure I am ready to do Grok
work at this level yet, but I will be eventually.

I believe it's very important that this relationship between the
grokkers and the ZCML directives they replace is explicit in the Grok
documentation, for three reasons:
- to make it easier for Zope 3 hackers to understand what Grok is doing
- to serve as a stepping stone for Grok users to graduate into deeper
Zope 3 development
- to help everyone do work which integrates lower-level Zope 3
programming with Grok.

Now that Martian is integrated, how does that affect the plan you
outlined in your message?
