[Zope] using ZPublisher.Client to add IOBtree

I am trying to use load_site to convert the unihan.txt into a zope object. I want to add many objects, so I think IOBtree is more suitable. How can I add a BtreeFolder (or IOBtreefolder) with ZPublisher.Client, The original load_site is Object.manage_addFolder(id="foldername") Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net
