    Write a warning to a file.  The default implementation calls

    resulting string to *file*, which defaults to ``sys.stderr``.  You may replace

-   ``warnings.showwarning``.

    *line* is a line of source code to be included in the warning
    message; if *line* is not supplied, :func:`showwarning` will
    try to read the line specified by *filename* and *lineno*.
