Subject: [PATCH] Add an RSS conversion stylesheet for dilbert.com

Since June 18, 2013 dilbert.com strips are not accessible anymore
directly from the RSS feed, this message is displayed instead:

  Dilbert readers - Please visit Dilbert.com to read this feature. Due
  to changes with our feeds, we are now making this RSS feed a link to
  Dilbert.com.

How unhandy is that, was it because of a management decision?
Maybe a parody dilbert strip is needed about this issue...
