                      5: # This script (when setup properly) will magically create an RSS 2.0 compliant feed
                      6: # that logs your cvs commits as well as a diff of the changes made.
                      7: #
                      8: # Run this from your CVSROOT/loginfo like:
                      9: #
                     10: #	/path/to/cvs2rss.pl %{sVv}
                     11: #
                     12: # Also, make sure your apache server has an AddType for rss like:
                     13: #
                     14: # 	AddType application/rss+xml .rss
                     15: #
                     16: # P.S. The "other" cvs2rss.pl isn't really cvs2rss, it is more like cvs2xml, boo!
                     17: # P.P.S. Parts of this are stolen from commit2rss.rb and the XML::RSS examples.
