   - `eslint-watch` - A never-ending task that watches your file system for changes to Cesium and runs ESLint on any changed source files.
   - `clean` - Removes all generated build artifacts.
   - `cloc` - Runs [CLOC](https://github.com/AlDanial/cloc) to count the lines of code on the Source and Specs directories. This requires [Perl](http://www.perl.org/) to execute.
-  - `sortRequires` - Alphabetically sorts the list of required modules in every `js` file. It also makes sure that the top of every source file uses the same formatting.
 - **Testing scripts** -- build and run the unit tests
   - `test` - Runs all tests with [Karma](http://karma-runner.github.io/0.13/index.html) using the default browser specified in the Karma config file.
   - `test-all` - Runs all tests with Karma using all browsers installed on the current system.

 Modules (files) should only reference modules in the same level or a lower level of the stack. For example, a module in `Scene` can use modules in `Scene`, `Renderer`, and `Core`, but not in `DataSources` or `Widgets`.
 
-- Modules in `define` statements should be in alphabetical order. This can be done automatically with `npm run sortRequires`, see the [Build Guide](../BuildGuide/README.md). For example, the modules required by `Scene/ModelAnimation.js` are:
-
-```javascript
-define([
-  "../Core/defaultValue",
-  "../Core/Event",
-  "../Core/JulianDate",
-  "./ModelAnimationLoop",
-  "./ModelAnimationState",

-  ModelAnimationLoop,
-  ModelAnimationState
