OPML="Outline Processor Markup Language"

*This is an XML format that allows you to export an outline, such as a list of RSS feeds. OPML importing and exporting gives a quick and easy way to move around a lot of RSS URL's in one fairly small package.

Some RSS feed reader applications, such as Bloglines, allow you to export all of the feeds you are reading as an OPML file.

An example Bloglines OPML file is attatched to this page (see "export" link above). This file can be imported to RSS Aggregators and feed readers, and web applications that support importing/exporting OPML.
