[Zope] webdav

Hello, The question is how do I disable webdav in Zope 2.7.0 In Zope 2.6 series there was z2.py which no longer exists and I keep getting error that -W option is unrecognized. I want nothing to do with webdav and I want to disable it completly, it's bugging me :) As I already write here I haven't found a document which would describe how to use custom_zodb.py file correctly. I want to increase some connection number so, I created a custom_zodb.py I found @ zope book. after that I can't see Database information from ZMI/Control_Panel. Vahur
