    coffee-script can also be installed via `npm install coffee-script`.
    This has the advantage of supporting multiple versions (of any Node libs)
    at the same time.

    Since coffee-script syntax changed pretty drastically between 0.7.2 and
    0.9.x, you may want to install it via npm instead.

    This formula may be retired from a future version of Homebrew.
