True. As a note how to solve his specific question, he can use the products
section in zope.conf generated by buildout:

(this is pseudo-buildout)

zope.conf = ...
    <product-config joachim>
    my-path ${buildout:directory}/parts/foo

Then in your code, you can retreive this data using:

    import zope.app.appsetup.product
