PEP 8 (legacy package)

The `pep8` package, version 1.7.1, is a Python style guide checker that verifies code against some of the conventions in PEP 8. This package has been renamed to `pycodestyle` to reduce confusion between the tool and the actual PEP 8 style guide document. While still installable, users are strongly encouraged to use `pycodestyle` instead. The package is in maintenance mode under its old name, with active development continuing as `pycodestyle`.
