+/**
+ * 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.
