+    longDescription = ''
+      dnstap implements an encoding format for DNS server events. It uses a
+      lightweight framing on top of event payloads encoded using Protocol
+      Buffers and is transport neutral.
+
+      dnstap can represent internal state inside a DNS server that is difficult
+      to obtain using techniques based on traditional packet capture or
+      unstructured textual format logging.
