How do I use dtml-with on the folder it is in? I have a folder with several documents in it, say like this: folderName DocumentA DocumentB and I want to display a summary of documents when the user visits folderName by putting this in folderName's index_html: <dtml-with self> <b><a href="<dtml-var id>"><dtml-var title</a></b> </dtml-with>
