+    6. examples/udp is enabled.  This will allow two MRF24J40 nodes to
+       exchange UDP packets.  Basic instructions:

+       On the server node:
+
+         nsh> ifconfig wpan0
+         nsh> udpserver &
+
+       The ifconfig command will show the IP address of the server.  Then on
+       the client node use this IP address to start the client:
+
+         nsh> udpserver <server-ip> &
+
+       Where <server-ip> is the IP address of the server that you got above.
+       NOTE: There is no way to stop the UDP test once it has been started
+       other than by resetting the board.
