Hi, I implemented the blue print https://blueprints.launchpad.net/zope.app.generations/+spec/zope.generations I extracted the parts of zope.app.generations which are ZMI independent into a new zope.generations package. Anyone who wants to review what I have done? (Although I already released the new packages as 3.7.0) Yours sincerely, -- Michael Howitz · mh@gocept.com · software developer gocept gmbh & co. kg · forsterstraße 29 · 06112 halle (saale) · germany http://gocept.com · tel +49 345 1229889 8 · fax +49 345 1229889 1 Zope and Plone consulting and development
