		<<03/29/01; 4:33:39 AM by JES

		<<04/07/01; 7:23:05 PM by JES

This listing is for code that runs in the OPML Editor environment. I created these listings because I wanted the search engines to index it, so that when I want to look up something in my codebase I don't have to use the much slower search functionality in my object database. Dave Winer.
