"""A setuptools based setup module.

See:
https://packaging.python.org/en/latest/distributing.html
https://github.com/pypa/sampleproject

Extra supported commands are:
* gen_tl, to generate the classes required for Telethon to run
* clean_tl, to clean these generated classes
* pypi, to generate sdist, bdist_wheel, and push to PyPi
