[Zope] module shared between products

[David Little]

I am developing a project which I have split into two products to avoid
having too many files in one place. I want to use a common base class in
each but I can't find out to do this while keeping all three product
directories together.

There is something about multiple product directories the archives:
" If you are prepared to edit Products/__init__.py add a line:
    __path__.append('yourpathhere') "

Is there a simpler way to do this?
