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: http://wheel.readthedocs.org/en/latest.
Requirements: setuptools>=0.8, and wheel.
'pip wheel' uses the bdist_wheel setuptools extension from the wheel package to build individual wheels.
