        """Intercept when the :meth:`.Engine.execution_options`
        method is called.

        The :meth:`.Engine.execution_options` method produces a shallow
        copy of the :class:`.Engine` which stores the new options.  That new
        :class:`.Engine` is passed here.   A particular application of this
        method is to add a :meth:`.ConnectionEvents.engine_connect` event
        handler to the given :class:`.Engine` which will perform some per-
        :class:`.Connection` task specific to these execution options.

        :param conn: The newly copied :class:`.Engine` object

        :param opts: dictionary of options that were passed to the
         :meth:`.Connection.execution_options` method.
