module Sprockets
  # Internal: Used for lazy loading processors.

  # Libraries should not use lazily loaded processors. They are only needed
  # internally by Sprockets since it has optionally dependencies such as
  # CoffeeScript that may not be available in the gem environment.

    #
    # See ProcessorUtils.autoload_processor for constructor method.

    # mod  - Parent Module of processor class/module
    # name - Symbol name of processor class/module
