[Zope] Upload Zip files

I am trying to use ZipFolder (http://zope.org/Members/snej/ZipFolder) to upload and unpack a zip file. It seems to work fine when used from the ZMI but I would like to use it outside of the ZMI. I managed to find the dhtml files used in the ZMI but I am having trouble adapting them. Any place where this is working outside of the ZMI? Samples? Other strategies?
