- /**
- * Twenty Eleven functions and definitions
- *
- * Sets up the theme and provides some helper functions. Some helper functions
- * are used in the theme as custom template tags. Others are attached to action and
- * filter hooks in WordPress to change core functionality.
- *
- * The first function, twentyeleven_setup(), sets up the theme by registering support
- * for various features in WordPress, such as post thumbnails, navigation menus, and the like.
- *
- * When using a child theme (see http://codex.wordpress.org/Theme_Development and
- * http://codex.wordpress.org/Child_Themes), you can override certain functions
- * (those wrapped in a function_exists() call) by defining them first in your child theme's
- * functions.php file. The child theme's functions.php file is included before the parent
- * theme's file, so the child theme functions would be used.
- *
- * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
- * to a filter or action hook. The hook can be removed by using remove_action() or
- * remove_filter() and you can attach your own function to the hook.
- *
- * We can remove the parent theme's hook only after it is attached, which means we need to
- * wait until setting up the child theme:
- *
- * <code>
- * add_action( 'after_setup_theme', 'my_child_theme_setup' );
- * function my_child_theme_setup() {
- * // We are providing our own filter for excerpt_length (or using the unfiltered value)
- * remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' );
- * ...
- * }
- * </code>
- *
- * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
- *
- * @package WordPress
- * @subpackage Twenty_Eleven
- * @since Twenty Eleven 1.0
