%description
    Skipper is an HTTP router and reverse proxy for service composition.
    It's designed to handle >300k HTTP route definitions with detailed
    lookup conditions, and flexible augmentation of the request flow
    with filters. It can be used out of the box or extended with custom
    lookup, filter logic and configuration sources.
