docutils 0.17 released

Release Notes

* Installing with ``setup.py`` now requires setuptools_.
  Alternatively, install with pip_.

  the free selection of reader, parser, and writer components.

* New, experimental wrapper to integrate the
  `recommonmark`__ Markdown parser for use with Docutils.

  __ https://pypi.org/project/recommonmark/

* HTML5 writer:

  - Use the new semantic tags <main>, <section>, <header>,
    <footer>, <aside>, <figure>, and <figcaption>.
    See ``minimal.css`` and ``plain.css`` for styling rule examples.

    Change the `initial_header_level`_ setting's default to "2", as browsers
    use the `same style for <h1> and <h2> when nested in a section`__.

  - Use HTML text-level tags <small>, <s>, <q>, <dfn>, <var>, <samp>, <kbd>,
    <i>, <b>, <u>, <mark>, and <bdi> if a matching class value
    is found in `inline` and `literal` elements.
    Use <ins> and <del> if a matching class value
    is found in `inline`, `literal`, or `container` elements.

  - New optional style ``responsive.css``, adapts to different screen
    sizes.

  - New option embed_images_.
