                      6: # that logs your cvs commits as well as a diff of the changes made.

                     12: # Also, make sure your apache server has an AddType for rss like:
                     13: #

                     17: # P.P.S. Parts of this are stolen from commit2rss.rb and the XML::RSS examples.
