/* 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' );
}
