    # This module makes it possible to use `app/presenters` with
    # Grape Entities. It instantiates model presenter and passes
    # options defined in the API endpoint to the presenter itself.

    #   present object, with: Entities::Something,
    #                   current_user: current_user,
    #                   another_option: 'my options'
    #
    # Example above will make `current_user` and `another_option`
    # values available in the subclass of `Gitlab::View::Presenter`
    # thorough a separate method in the presenter.
    #
    # The model class needs to have `::Presentable` module mixed in
    # if you want to use `API::Helpers::Presentable`.
