Creating an RPM from a Python package

On your dev host you need Python, virtualenv and Docker installed.

On your build host (or container) you need python and rpm-build packages.

Install cookiecutter Python package in your Python virtualenv. It can be used to create instalable Python packages. Most importantly, it creates the setup.py file for you.
