mosquitto-clients - 2.0.20-1 main

This is two MQTT version 5.0/3.1.1/3.1 command line clients. mosquitto_pub can
be used to publish messages to a broker and mosquitto_sub can be used to
subscribe to a topic to receive messages.
.
MQTT provides a method of carrying out messaging using a publish/subscribe
model. It is lightweight, both in terms of bandwidth usage and ease of
implementation. This makes it particularly useful at the edge of the network
where a sensor or other simple device may be implemented using an arduino for
example.
