The boilerplate now uses the power of grunt for several automated tasks, including compiling SCSS files and linting javascript. It can also be used to concatenating and uglifying all app-specific javascript into a neat little package ready for production.
Running grunt watch in the root of the project will start grunt watching your SCSS and JS files, compiling and linting respectively as you code. Running grunt will link, concatenate and uglify your javascript into assets/js/prod/main.min.js. It will also lint the end product to avoid any nasty surprises. Also it does a compass compile of your SCSS files in compressed mode.
Future plans include using a front-end package manager like Bower, but I'm not sure the benefits are there for us just yet.
####Now get out there and smash those targets.
