 * The Aurora theme is a base theme designed to be easily extended by sub
 * themes. You should not modify this or any other file in the Aurora theme
 * folder. Instead, you should create a sub-theme and make your changes there.
 * In fact, if you're reading this, you may already off on the wrong foot.
 *
 * See the project page for more information:
