[Zope] How to include packages in INSTANCE_HOME

[Max M]

Trying to set up my sites to run as "INSTANCE_HOME"

I have a few packages that is defined outside the Products directory, like:

"<ZOPE>/lib/python/mypackage"


I have tried putting these in my INSTANCE_HOME directory, but my 
products cannot find them. Isn't it possible to do it like that?

Do I really need to install those packages under my Zope install, or 
should I just put them in a special directory? or?
