%description
    NSQ is a realtime distributed messaging platform designed to operate
    at scale, handling billions of messages per day. It promotes
    distributed and decentralized topologies without single points of
    failure, enabling fault tolerance and high availability coupled with
    a reliable message delivery guarantee.
