+      If you would like to access the bug list from another program 
+      it is often useful to have the list returned in something other
+      than HTML. By adding the ctype=type parameter into the bug list URL
+      you can specify several alternate formats. The supported formats
+      are: Comma Separated Values (ctype=csv), iCalendar (ctype=ics),
+      RDF Site Summary (RSS) 1.0 (ctype=rss), ECMAScript, also known
+      as JavaScript (ctype=js), and finally Resource Description Framework
+      RDF/XML (ctype=rdf).
