[Zope3-dev] How does Zope.Configuration work?

[Jeremy Hylton]

I wanted to better understand what all the directives in .zcml files
meant.  I assume they are connected to specific class / methods /
functions in the Zope package.  So when I write <zmi:factoryFromClass
...> this is in some way connected to some code in Zope.App.ZMI
package.

Assuming this model is correct, how does the implementation connect
directives to code?  I've been trying to read the xmlconfig code, but
I find it hard going.  I'm not too familiar with XML handling code and
there seems to be a lot of abstraction / indirection.  Could someone
offer some hints about what's going on?  I'd be happy to turn them
into some comments or a doc string for the benefit of future readers.
