"""Wrapper around Flake8 to enable multiprocessing on all operating systems.
As of Python 3.8, macOS's default "start method" for multiprocessing is `spawn`. Flake8
requires a "start method" of `fork`, and disables multiprocessing if it detects `spawn`
or some other "start method". This script enables the `fork` start method before passing
along any command-line arguments to `flake8`.
This has never caused me any problems, but note that they disabled this for a reason:
Flake8's plugin interface doesn't work with `spawn`, and the maintainer says that `fork`
is "pretty broken" on macOS.
