-  # Rails::LogSubscriber is an object set to consume ActiveSupport::Notifications
-  # on initialization with solely purpose of logging. The log subscriber dispatches
-  # notifications to a regirested object based on its given namespace.
-  #
-  # An example would be Active Record log subscriber responsible for logging queries:
-  #
-  #   module ActiveRecord
-  #     class Railtie
-  #       class LogSubscriber < Rails::LogSubscriber
-  #         def sql(event)
-  #           "#{event.payload[:name]} (#{event.duration}) #{event.payload[:sql]}"
-  #         end
-  #       end
-  #     end
-  #   end
-  #
-  # It's finally registed as:
-  #
-  #   Rails::LogSubscriber.add :active_record, ActiveRecord::Railtie::LogSubscriber.new
-  #
-  # So whenever a "sql.active_record" notification arrive to Rails::LogSubscriber,
-  # it will properly dispatch the event (ActiveSupport::Notifications::Event) to
-  # the sql method.
-  #
-  # This is useful because it avoids spanning several log subscribers just for logging
-  # purposes(which slows down the main thread). Besides of providing a centralized
-  # facility on top of Rails.logger.
-  #
-  # Log subscriber also has some helpers to deal with logging and automatically flushes
-  # all logs when the request finishes (via action_dispatch.callback notification).
