To help you with studying the Clojure language, I spent some time this afternoon coding up a simple example of a Clojure application. This example app will take an input file consisting of names and produce an output file where the names are sorted. Take a look at the source code and the test cases and see if it helps you pick up some more Clojure and understand how little snippets of Clojure code can be assembled into a working application.
