    # == Sucker Punch adapter for Active Job
    #
    # Sucker Punch is a single-process Ruby asynchronous processing library.
    # It's girl_friday and DSL sugar on top of Celluloid. With Celluloid's
    # actor pattern, we can do asynchronous processing within a single process.
    # This reduces costs of hosting on a service like Heroku along with the
    # memory footprint of having to maintain additional jobs if hosting on
    # a dedicated server. All queues can run within a single Rails/Sinatra
    # process.
    #
    # Read more about Sucker Punch {here}[https://github.com/brandonhilkert/sucker_punch].
    #
    # To use Sucker Punch set the queue_adapter config to +:sucker_punch+.

    #   Rails.application.config.active_job.queue_adapter = :sucker_punch
