Dejour provides an easy, works out of the box experience for the Clojure programming language. Clojure is a JVM-hosted, functional, general-purpose LISP variant that is especially adept at concurrent programming. You can find the clojure source and original downloads at http://clojure.org.

Unfortunately, while clojure.org provides the superb Clojure language as well as clojure-contrib (a set of useful libraries) there are a few things missing. The most important missing bit is a script that will run Clojure. Also missing is the very useful JLine providing a more robust interactive clojure interpreter or REPL.

The Dejour project pulls all of this together in a single easy to get, easy to install download. Dejour currently works on Linux, Macs, and Windows.
