Setuptools integration

Upon installation, Flake8 enables a setuptools command that checks Python files declared by your project.

Running python setup.py flake8 on the command line will check the files listed in your py_modules and packages. If any warning is found, the command will exit with an error code:

$ python setup.py flake8

Also, to allow users to be able to use the command without having to install flake8 themselves, add flake8 to the setup_requires of your setup() like so:

setup(
    name="project",
    packages=["project"],

    setup_requires=[
        "flake8"
    ]
)
