Well actually its not so hard as it seems. And products are more
easy to handle then external methods (initializing is more clear).
All you need to create a folder with a good name for your project
in the instance or common Products folder (depending on your
zope.conf ) then copy
then you edit this file to your likings based on both the documentation
(yes I know this is a bit sparse) and the hints given in that file.
Not you can define your own classes and functions in this file as
well. For better structure you are encouraged to create actual
module files in that directory instead of writing everything
into __init__.py once your create more then just a toolset.
