    Build Wheel archives for your requirements and dependencies.

    Wheel is a built-package format, and offers the advantage of not
    recompiling your software during every install. For more details, see the
    wheel docs: https://wheel.readthedocs.io/en/latest/

    Requirements: setuptools>=0.8, and wheel.

    'pip wheel' uses the bdist_wheel setuptools extension from the wheel
    package to build individual wheels.
