 	Show contents of specified routing tables, that is routes, their metrics
 	and (in case the <cf/all/ switch is given) all their attributes.
 
 	<p>You can specify a <m/prefix/ if you want to print routes for a
 	specific network. If you use <cf>for <m/prefix or IP/</cf>, you'll get
 	the entry which will be used for forwarding of packets to the given
-	destination. By default, all routes for each network are printed with
+	destination. Finally, if you use <cf>in <m/prefix/</cf>, you get all
+	prefixes covered by the given prefix.
+	By default, all routes for each network are printed with
 	the selected one at the top, unless <cf/primary/ is given in which case
 	only the selected route is shown.
