+This test checks whether zones configured with "type mirror;" behave as
+expected.
+
+ns1 is an authoritative-only server. It only serves the root zone, which is
+mirrored by ns3.
+
+ns2 is an authoritative-only server. It serves a number of zones, some of which
+are delegated to it by ns1 and used in recursive resolution tests aimed at ns3
+while others are only served so that ns3 has a primary server to mirror zones
+from during various tests of the mirror zone implementation.
+
+ns3 is a recursive resolver. It has a number of mirror zones configured. This
+is the only server whose behavior is being examined by this system test.
