+/**
+ * @file
+ * Theme override for a menu block.
+ *
+ * Available variables:
+ * - plugin_id: The ID of the block implementation.
+ * - label: The configured label of the block if visible.
+ * - configuration: A list of the block's configuration values.
+ * - label: The configured label for the block.
+ * - label_display: The display settings for the label.
+ * - provider: The module or other provider that provided this block plugin.
+ * - Block plugin specific settings will also be stored here.
+ * - content: The content of this block.
+ * - attributes: HTML attributes for the containing element.
+ * - id: A valid HTML ID and guaranteed unique.
+ * - title_attributes: HTML attributes for the title element.
+ * - content_attributes: HTML attributes for the content element.
+ * - title_prefix: Additional output populated by modules, intended to be
+ * displayed in front of the main title tag that appears in the template.
+ * - title_suffix: Additional output populated by modules, intended to be
+ * displayed after the main title tag that appears in the template.
+ *
+ * Headings should be used on navigation menus that consistently appear on
+ * multiple pages. When this menu block's label is configured to not be
+ * displayed, it is automatically made invisible using the 'visually-hidden' CSS
+ * class, which still keeps it visible for screen-readers and assistive
+ * technology. Headings allow screen-reader and keyboard only users to navigate
+ * to or skip the links.
+ * See http://juicystudio.com/article/screen-readers-display-none.php and
+ * http://www.w3.org/TR/WCAG-TECHS/H42.html for more information.
