What SCM-based blog engines are there?

Question

Recently I came across a blog engine that works in quite unusual way. It polls a git repository and publishes a blog post after something new has been found in the repo. The post is generated as a static HTML and put somewhere in public_html. Homepage gets updated.

Do you know any git/hg/svn based blog engines like this? Let's create a list of all SCM-based blog engines as a community wiki.
