 # 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/)
