+ * AHAH is a method of making a request via Javascript while viewing an HTML
+ * page. The request returns a small chunk of HTML, which is then directly
+ * injected into the page.
+ *
+ * Drupal uses this file to enhance form elements with #ahah[path] and
+ * #ahah[wrapper] properties. If set, this file will automatically be included
+ * to provide AHAH capabilities.
