/**
 * GULP file
 *
 * This Node script is executed when you run `gulp`. It's purpose is
 * to load the Gulp tasks in your project's `tasks` folder, and allow
 * you to add and remove tasks as you see fit.
 *
 * WARNING:
 * Unless you know what you're doing, you shouldn't change this file.
 * Check out the `tasks` directory instead.
