    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.
   18: #
   19: # Version 1.0 - 08.24.04 RSS Compliant, no cvs diff capability yet..
   20: # Version 1.1 - 08.31.04 Adding CVS Diff capability
   21: # Edit by Guy Albertelli, -- corrected the packaging of Entities
   22: #                          - commits now <pre>ed
   23: #                          - removed html rants
