Github continuous integration service for libStorageMgmt
This service is based on the information available from: https://developer.github.com/guides/building-a-ci-server/ except that it's written in python instead of ruby. These examples use http://bottlepy.org and http://www.python-requests.org
Some interesting pieces of functionality that others may want to leverage (see actual code for more detail, these are excerpts):
