    @brief Example of using the XBeeApi library to broadcast a message
-          This example has a minimum of error checking in order
-          to keep the code compact
+          This example has more error checking than
+          XBeeApiSimpleBroadcast example and should improve the changes
+          of detecting and diagnosing a problem.
