        Parameters
        ----------
        fname : str
            The name of the file to execute.  The filename must have a
            .ipy or .ipynb extension.
        shell_futures : bool (False)
            If True, the code will share future statements with the interactive
            shell. It will both be affected by previous __future__ imports, and
            any __future__ imports in the code will affect the shell. If False,
            __future__ imports are not shared in either direction.
        raise_exceptions : bool (False)
            If True raise exceptions everywhere.  Meant for testing.
