USAGE="Run static code checkers (but not unit tests)

This script expects to be run from the repository's root directory so the tools
can find their configuration files.

USAGE:

OPTIONS:
    --help, -h: Show this help and exit

EXIT VALUES:
    - 0     Success
    - 1     Invalid option/argument
    - 2     Python syntax error
    - 4     Python format error (black, isort)
    - 8     Python linter error (mypy, pylint, django)
    - 16    JavaScript error (eslint)
