			<<Created. When the responder gets a file-not-found, it checks to see if the file exists without its extension. This allows us to give the user a choice of editors for files we serve. You can start a page using Notepad and then upgrade to an outliner and the links don't break. It's also possible to completely omit the extension in a link.

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.
