+If the \fIstash-agent-options\fR parameter is true for a given client,
+the server will record the relay agent information options sent during
+the client's initial DHCPREQUEST message when the client was in the
+SELECTING state and behave as if those options are included in all
+subsequent DHCPREQUEST messages sent in the RENEWING state.   This
+works around a problem with relay agent information options, which is
+that they usually not appear in DHCPREQUEST messages sent by the
+client in the RENEWING state, because such messages are unicast
+directly to the server and not sent through a relay agent.
