Light-weight CMS backed by git

[apevec]

Part of RDO website is generated from the source managed in git repository:

• https://www.rdoproject.org/packaging/ is generated from https://github.com/redhat-openstack/openstack-packaging-doc

The rest of the website is currently backed by a wiki and better would be to have a light-weight CMS backed by git.
Any suggestions for a CMS doing that?

https://middlemanapp.com/ was suggested
probably using https://github.com/OSAS/middleman-springboard

I would suggest pelican https://pypi.python.org/pypi/pelican
That could integrate tightly into git.
