/**
 * How to run grunt tasks:
 *   - At project root, run 'npm install' - It will install nodedependencies declared in package,json in <root>/.node_modules
 *   - install grunt CLI tools globally, run 'npm install -g grunt-cli'
 *   - run a grunt target defined in Gruntfiles.js, ex: 'grunt lint'
 *
 * Note: The 'ghost' grunt task have special deps on CasperJS and phantomjs.
 *       For now, It's configured to run only on TravisCI where these deps are
 *       correctly defined.
 *       If you run this task locally, it may require some env set up first.
