[Zope] dynamic dtml-tree

I found dtml-tree today, and it provides the exact UI I want to use. I even managed to make it work to display the contents of the current folder. I haven't yet seen any docs that describe how the dtml-tree works. The page that I will generate will be based on data from several SQL databases and consolidated by a Python Script. I need to know the structure of the data that dtml-tree expects and how to handle expansion requests. Any pointers, docs, discussions, or examples are greatly appreciated. -D -- Windows, hmmm, does it come with a GUI interface that works or just pretty blue screens?
