jetfuel-blackbox/src/main/blackbox/web/plugin/backbone/sync.js

Currently, BlackBox is a boilerplate client-side application framework, built on top of the JetFuel build system and Grunt, Backbone, RequireJS, JetRunner unit test server (Mocha BDD/TDD test framework + PhantomJS + SauceLabs cloud integration), Dust (and Plate Django port) for templating (both client and server-side), Sass, Express dynamic web server, etc. BlackBox is the template used for JetFuel's basic `init` command.
