         Create summary page for 'queue' APIs
             The former queue(3) page was rather unwieldy, as it attempted to
-	    describe too many APIs. After splitting that content out into a
-	    number of smaller pages ( circleq.3, list.3, slist.3, stailq.3,
-	    and tailq.3) move the much-reduced queue(3) page, which is now
