alright, done fiddling. CoffeeScript 0.2.0

coffee compiles CoffeeScript source files into JavaScript.

Usage:
  coffee path/to/script.coffee
    -i, --interactive                run a CoffeeScript REPL (requires Narwhal)
    -r, --run                        compile and run a script (requires Narwhal)
    -o, --output [DIR]               set the directory for compiled JavaScript
    -w, --watch                      watch scripts for changes, and recompile
    -p, --print                      print the compiled JavaScript to stdout
    -l, --lint                       pipe the compiled JavaScript through JSLint
    -e, --eval                       compile a cli scriptlet or read from stdin
    -t, --tokens                     print the tokens that the lexer produces
    -v, --verbose                    print at every step of code generation
    -n, --no-wrap                    raw output, no safety wrapper or vars
        --install-bundle             install the CoffeeScript TextMate bundle
        --version                    display CoffeeScript version
    -h, --help                       display this help message outside of the coffee-script directory
