[Zope] Product seeking products: how?

[Terry Hancock]

Hi all,

I need to create a plugin architecture for a product I'm
developing, since I want to encourage third-party
contributions, and define a clean way for them to work
together.

Given that Zope already has a nice plugin architecture,
AKA Products, it seems like the most logical solution is
to use that.  

Thus, my plugins would just be Zope products which
implement a certain interface.

But it is unclear to me how best to go about finding
them. It seems like the most plug-n-play way for this
to work would be for my product to collect all the
plugins when Zope restarts -- but there are some
problems, such as how to run code after all the other
products have loaded.

Is there any example code I should be looking at
to do this (i.e. other products that behave like this)?

Thanks,
Terry
