Abracadabra, PropertyTools, Mailboxer - they moved to
[http://www.iungo.org/products]. I can't praise them enough. In my
opinion Maik wrote the stuff exactly in the way Zope2 was ment to be
used. I like it a lot, use them all the time.
Skins - a varation of the SkinnedFolder
<http://www.dieter.handshake.de/pyprojects/zope/#bct_sec_3.7>, as seen
in CMF. It gives you a transparent folder for skins, and also
DirectoryViews, meaning that you can put your templates into the
filesystem, managed by svn.
I got my version from zwarehouse
<http://www.zwarehouse.org/wiki/ZwarehouseDependencies>, and modified it
slightly so that it treats metadata correctly - Skins.tgz .
