%description
    Disque is ongoing experiment to build a distributed, in memory,
    message broker. Its goal is to capture the essence of the "Redis as
    a jobs queue" use case, which is usually implemented using blocking
    list operations, and move it into an ad-hoc, self-contained,
    scalable, and fault tolerant design, with simple to understand
    properties and guarantees, but still resembling Redis in terms of
    simplicity, performances, and implementation as a C non-blocking
    networked server.
