  # This Makefile offers convience shortcuts into any Node.js project that utilizes npm scripts.
  # It functions as a wrapper around the actual listed in `package.json`
  # So instead of typing:
  #
  #  $ npm script build:assets
  #
  # you could also type:
  #
  #  $ make build-assets
  #
  # Notice that colons (:) are replaced by dashes for Makefile compatibility.
  #
  # The benefits of this wrapper are:
  #
  # - You get to keep the the scripts package.json, which is more portable
  #   (Makefiles & Windows are harder to mix)
  # - Offer a polite way into the project for developers coming from different
  #   languages (npm scripts is obviously very Node centric)
  # - Profit from better autocomplete (make <TAB><TAB>) than npm currently offers.
  #   OSX users will have to install bash-completion
  #   (http://davidalger.com/development/bash-completion-on-os-x-with-brew/)
