[Zope] from zclasses to zclasses...

first, thanx ender for pointing me in the right direction about excel to zclasses conversion now i have to convert quite a lot of zclasses from an old zope (which i definitely don't want to keep) to some new classes on a new zope on another machine how can i do that ? until now, i generated forms to create those classes, but i can't do that for *many* elements i know there must be a way, but right now, i'm in the dark... b
