%description
Mosquitto is an open source (BSD licensed) message broker that
implements the MQ Telemetry Transport protocol version 3.1. MQTT
provides a lightweight method of carrying out messaging using a
publish/subscribe model. This makes it suitable for "machine to
machine" messaging such as with low power sensors or mobile devices
such as phones, embedded computers or micro-controllers like the
Arduino.

%description clients
This is two MQTT version 3 clients. The first can publish messages to
a broker, the second can subscribe to multiple topics on a broker.
