[Zope] Inporting HTML-ish sites

I'm about to import into Zope (possibly Zope-CMF) a largish site currently prototyped in HTML. The import will be one-way (we'll never move back to HTML) so we can make whatever changes are needed/wanted in the site representation. Has anyone written a smart import package that does anything more than copy upload files to DTML-documents (or their template equivalent) and map directories into folders. I did a cursory search and found nothing of this ilk. I have seen reverences to a "sitecopy" product but did not find it. Thanks. -dra
