  // A set of basic code conventions (similar to a .jshintrc file) designed to
  // and encourage quality and consistency across your Sails app's code base.
  // These rules are checked against automatically any time you run `npm test`.
  // 
  // > An additional eslintrc override file is included in the `assets/` folder
  // > right out of the box.  This is specifically to allow for variations in acceptable
  // > global variables between front-end JavaScript code designed to run in the browser
  // > vs. backend code designed to run in a Node.js/Sails process.
  //
  // > Note: If you're using mocha, you'll want to add an extra override file to your
  // > `test/` folder so that eslint will tolerate mocha-specific globals like `before`
  // > and `describe`.
