  module Dumpers

    # The dumper is a specific Logger::Backend.
    #
    # It react to method calls by writting in the output.
    # The output must be acceded like that:
    #
    #   * Using the print method
    #   * Using the puts method
    #   * Using the << method
    #
    # If you really need to access to the real outputs use each_output.
    #
    # You can safely call flush in your methods because this method take care
    # of closed and unflushable outputs.
