I have a PersistentList and PersistentDict library available for download over at zope.org. I had the tarball put the library in lib/python/ZODB, which is clearly wrong (must of had a brain cramp that day :).

Question -- where should it go?

It could install itself as if it were a Zope Product: lib/python/Products/PersistentListDict/(PersistentList.py, PersistentDict.py, readme.txt)

...

However... it's not really a Product. It's a Python class to be called from Python code. It doesn't participate in or have anything to do with the Zope product interface at all.

Andrew - Probably the best place is a package in the lib/python/Shared/ directory of the Zope installation. This is the place for packages that are not product-specific. For example, lib/python/Shared/DC contains packages from Digital Creations - you might want to put your stuff in lib/python/Shared/Foo/PersistentListDict (where "Foo" is your organization or some other contextual name to distinguish your packages).
