     <title>Red Hat Bugzilla</title>
-    <para>
-      Red Hat Bugzilla is probably the most popular Bugzilla variant
-      on the planet. One of the major benefits of Red Hat Bugzilla is
-      the ability to work with Oracle, MySQL, and PostGreSQL databases
-      serving as the back-end, instead of just MySQL.  Dave Lawrence
-      has worked very hard to keep Red Hat Bugzilla up-to-date, and
-      many people prefer the snappier-looking page layout of Red Hat
-      Bugzilla to the default Mozilla-standard formatting.
