# Short-Description:	mosquitto MQTT v3.1 message broker
# Description: 
#  This is a message broker that supports version 3.1 of the MQ Telemetry
#  Transport (MQTT) protocol.
#  
#  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.
