Source code for scraper_lib.cli

"""Console entry point for ScraperLib.

Every documented way of starting the CLI lands here:

* ``scraper --url ...``             -- the ``console_scripts`` entry point
* ``python -m scraper_lib ...``     -- via :mod:`scraper_lib.__main__`
* ``python -m scraper_lib.cli ...`` -- via the ``__main__`` guard below

The flags themselves are defined once, in
:meth:`scraper_lib.ScraperLib.build_arg_parser`, which is also what
``docs/cli.rst`` renders. There is no second copy to drift.
