/**


 * TwentyTen 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, twentyten_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', 'twentyten_excerpt_length' );


 *     ...


 * }


 * </code>


 *


 * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
