Cryogen is a simple static site generator built with Clojure — Cryogen (by Carmen La).
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 or AsciiDoc 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.
