You'll need coffeescript to build this project.
To use the included Makefile, set the environment variable CLOSURE_COMPILER to
execute Google's Closure Compiler jar:
export CLOSURE_COMPILER="java -jar
~/usr/local/closure-compiler/build/compiler.jar"
By default it will try to run the command closure-compiler which should be
available if you use Homebrew to install
Google Closure Compiler.
