Command Line Interface
======================
The command line interface of Flake8 is modeled as an application via
:class:`~flake8.main.cli.Application`. When a user runs ``flake8`` at their
command line, :func:`~flake8.main.cli.main` is run which handles
management of the application.
User input is parsed *twice* to accomodate logging and verbosity options
passed by the user as early as possible.
This is so as much logging can be produced as possible.
The default flake8 options are registered by
:func:`~flake8.main.options.register_default_options`. Trying to register
these options in plugins will result in errors.
