 =head1 DESCRIPTION
 
 This provides two different thread views for Buscador - traditional 
-'JWZ' style view and a rather funky looking 'lurker' style. They can be 
+'JWZ' style view, a rather funky looking 'lurker' style and a thread
+arc style cribbed from the IBM ReMail research project. They can be 
 accessed using 
 
 
     ${base}/mail/thread/<id>
     ${base}/mail/lurker/<id>
+    ${base}/mail/arc/<id>
 
-
 where C<id> can be the message-id of any message in the thread. neat, huh?
