The OPML Auto-discovery Bookmarklet scans the header of a Web page, and displays a list of OPML outline files in a box in the top-left corner of the browser. For completeness' sake any RSS feeds are listed too. The bookmarklet lists each of these files as Grazr hyperlinks: when you click on any of these a Grazr window is opened in a new tab, displaying the contents of the OPML file or the RSS feed. Note that if a "title" attribute is provided, the bookmarklet will take that. Otherwise the url to the file is used to populate the box.
