+;; There is a bug in Leiningen 1.6.2 which requires that you have
+;; Clojure 1.2.1 in the local maven repository when you are working on a
+;; Clojure 1.3 project. If the first project that someone works on
+;; with Leiningen is a Clojure 1.3 based project then they will
+;; encounter this problem.
+
+;; A lot of people have run into this with ClojureScript One so we
+;; have added a workaround.
+
+;; Leiningen includes an `install` task which, for some unknown reason,
+;; takes a long time to run. Below, we have extracted just the part
+;; of that task that we need to get a dependency from a maven repository.
