+ * @file maintenance.tpl.php
+ * Displays the site in off-line and update modes. Also when the database is
+ * not available.
+ *
+ * To override this template, copy it into either
+ * "sites/example.com/maintenance" or "sites/all/maintenance". If your
+ * running a multi-site installation, placing it into
+ * "sites/all/maintenance" will apply to all installations. Overriding
+ * through a specific installation will apply only to that installation.
+ *
+ * This also applies independently to the url of the logo, the "style.css"
+ * file and the "favicon.ico" file which is output through the $head variable.
+ * The style sheet and logo will default to the files inside
+ * "themes/garland/minnelli" when an override isn't found.
+ *
+ * Variables available:
+ * - $head_title: The title of the page for use inside the head tag.
+ * - $head: Outputs various header elements.
+ * - $styles: Style sheets for the page.
+ * - $scripts: Scripts for the page.
+ * - $site_title: The name of the site. When the database is offline, it will
+ *   default to "Drupal".
+ * - $logo: The url of the logo. This depends on where it's found first.
+ * - $title: The page title.
+ * - $content: Body content.
+ * - $messages: Messages indicating status or errors.
+ * - $left: Left block region. This is hard set so no matter what regions are
+ *   used inside your theme. This region will always exist.
+ * - $right: Right block region. The same above conditions apply.
+ * - $base_path: The base directory of the installation. At the very least, it
+ *   will output "/".
+ * - $path_to_theme: This will point to the directory where this template file
+ *   exists.
