"""
    Pygments Markdown Lexer – A Markdown lexer for Pygments to
    highlight Markdown code snippets.

    This setuptools script follows the DRY principle and tries to
    minimize repetition of project metadata by loading it from other
    places (like the package's `__init__.py`). Incidently, this makes
    the script almost identical between different projects.

    It is also importable (by using the usual `if __name__ == '__main__'`
    idiom), and exposes the project's setup data in a `project` dict.
    This allows other tools to exploit the data assembling code contained
    in here, and again supports the DRY principle. The `rituals` package
    uses that to provide Invoke tasks that work for any project, based on
    its project metadata.
