Long ago I rename zope.etree -> z3c.etree and zope.webdav -> z3c.dav to move
it out of the zope namespace. At the time I seemed to have copied instead of
moved the projects in subversion. I only released when Sidnei checked in
change to zope.etree. I have just removed them.
Aplogise to Sidnei again and to any one else you may have used / be using
them. Please use the released z3c.etree or z3c.dav packages instead.
