	  Qt is a cross-platform application and UI framework for
	  developers using C++.

	  The Qt MQTT module provides a standard compliant
	  implementation of the MQTT protocol specification. It
	  enables applications to act as telemetry displays and
	  devices to publish telemetry data.  The supported versions
	  are MQTT 3.1, MQTT 3.1.1, and MQTT 5.0.
