With lein-dalap you don't need to fork your Clojure project in order to make it Clojurescript compatible. Use the same source files to target both the JVM and JS.
Starting with working Clojure source files, lein-dalap walks your code and translates the JVM platform specific bits into the equivalent Clojurescript. You just need to add a few meta tags and, optionally, specify some CSS-like rules.
lein-dalap has sane defaults and provides a simple mechanism to target particular Clj forms / types and transform them as you need.
