-  This is a sample program to illustrate the use of the MQTT Client library

-  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 Linux
-  system libraries.
