The instructions in the README.txt and on zope.org are a little vague.. How, indeed, do I " build this extension using the included Setup file in the ZPatterns directory" I can see the Setup file but that is about it. I would be more than happy to write up some documentation (on Zope.org) if someone sends me the answer. RH Linux 6.2, Zope 2.2.2, Latest ZPatterns Thanks, J
