[Zconfig] (Newbie on zconfig) stuck extending zope.conf for my product

[Gilles Lenfant]

Hi,

I read in depth the PDF that ships with Zope 2.9 about zconfig and the 
small example that's in default "zope.conf", and the various source 
files in ZConfig and others places with a component.xml, but I'm still 
stuck extending the zope.conf using an "%import ..." to provide 
configuration data to a personal product.

Are there examples of simple products doing this somewhere ? Or a 
tutorial for such a use case ?

Many thanks in advance.
