Zope Toolkit
As a result of the development of Zope 3 / BlueBream, there are now many independent Python packages used and developed as a part of BlueBream, and although many of these are usable outside of BlueBream, many are not. The Zope Toolkit (ZTK) project was started to clarify which packages were usable outside BlueBream, and to improve the re-usability of the packages. Thus the Zope Toolkit is a base for the Zope frameworks. Zope 2.12 is the first release of a web framework that builds on Zope Toolkit, and Grok and BlueBream were set to have releases based on the ZTK during 2010.
