+  This is a sample program to illustrate the use of the MQTT Client library
+  on the mbed platform.  The Client class requires two classes which mediate
+  access to system interfaces for networking and timing.  As long as these two
+  classes provide the required public programming interfaces, it does not matter
+  what facilities they use underneath. In this program, they use the mbed
+  system libraries.
