+/**
+ * @file
+ * Implement a simple, clickable dropbutton menu.
+ *
+ * See dropbutton.theme.inc for primary documentation.
+ *
+ * The javascript relies on four classes:
+ * - The dropbutton must be fully contained in a div with the class
+ *   ctools-dropbutton. It must also contain the class ctools-no-js
+ *   which will be immediately removed by the javascript; this allows for
+ *   graceful degradation.
+ * - The trigger that opens the dropbutton must be an a tag wit hthe class
+ *   ctools-dropbutton-link. The href should just be '#' as this will never
+ *   be allowed to complete.
+ * - The part of the dropbutton that will appear when the link is clicked must
+ *   be a div with class ctools-dropbutton-container.
+ * - Finally, ctools-dropbutton-hover will be placed on any link that is being
+ *   hovered over, so that the browser can restyle the links.
+ *
+ * This tool isn't meant to replace click-tips or anything, it is specifically
+ * meant to work well presenting menus.
