"""Module that contains the command line app.

Why does this file exist, and why not put this in __main__?

You might be tempted to import things from __main__ later, but that will

cause problems: the code will get executed twice:

- When you run `python -m sqlparse` python will execute

``__main__.py`` as a script. That means there won't be any

``sqlparse.__main__`` in ``sys.modules``.

- When you import __main__ it will get executed again (as a module) because

there's no ``sqlparse.__main__`` in ``sys.modules``.
