# Solaris 10 SMF-style services.

    Support for Sun's new Service Management Framework.

    Starting a service is effectively equivalent to enabling it, so there is
    only support for starting and stopping services, which also enables and
    disables them, respectively.

    By specifying `manifest => "/path/to/service.xml"`, the SMF manifest will
    be imported if it does not exist.
