+
+Change a hold request's priority or cancel it.
+
+C<$rank> specifies the effect of the change. If C<$rank>
+is 'W' or 'n', nothing happens. This corresponds to leaving a
+request alone when changing its priority in the holds queue
+for a bib.
+
+If C<$rank> is 'del', the hold request is cancelled.
+
+If C<$rank> is an integer greater than zero, the priority of
+the request is set to that value. Since priority != 0 means
+that the item is not waiting on the hold shelf, setting the
+priority to a non-zero value also sets the request's found
+status and waiting date to NULL.
+
+The optional C<$itemnumber> parameter is used only when
+C<$rank> is a non-zero integer; if supplied, the itemnumber
+of the hold request is set accordingly; if omitted, the itemnumber
+is cleared.
+
+FIXME: Note that the forgoing can have the effect of causing
+item-level hold requests to turn into title-level requests. This
+will be fixed once reserves has separate columns for requested
+itemnumber and supplying itemnumber.
