%description
    NATS is an open source, lightweight, high-performance cloud native
    infrastructure messaging system. It implements a highly scalable and
    elegant publish-subscribe (pub/sub) model. The performant nature of
    NATS make it an ideal base for building modern, reliable, scalable
    cloud native distributed systems. This is the high performance
    server for NATS.
