Cryogen static site generator
From its documentation:
Cryogen is shipped on Leiningen so setup is fuss free and there's no need to mess with databases or other CMS systems.
Cryogen reads through a directory containing your Markdown content, compiles it into HTML and injects the content into your templates with the Selmer templating system. It then spits out a ready-to-publish website complete with a sitemap and RSS feed.
