The REPL pane on the bottom-left is a convenient scratchpad to try out Clojure commands. The build pane on the bottom-right gives you access to all the Leiningen commands to run, build, and test your project. These same buttons will work with Clojure/Android and ClojureScript projects, due to the included lein-droid
plugins. This makes Nightcode the easiest way to get started with Clojure.
