YAWT is Yet Another Weblog Tool, written in python. It's a blogging/CMS engine in the style of blohg, jekyll and other DVCS based blogging tools.
The idea is that you store your blog entries in a DVCS and we use that metadata to glean information like the post time, last modification time, and author.
yawt sports a plugin architecture and comes with plugins to support features such as tags, archives, full text search, and markdown support. DVCS support included git and mercurial for the metadata support.
