I was worried this would be proprietary commons clause licensed like the creators vespen project... but I was pleasantly surprised that is is open source, Apache (real Apache) licensed! Further, it appears that Vespene has been open sourced under the Apache license as well!

Thank you Michael for creating these projects and releasing them as Open Source! I am a big user of Ansible, and have often wished there was a good way to write plays in Python. I will be keeping a close on on both of these projects!
