/**
|
|
* Twenty Twelve 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, twentytwelve_setup(), sets up the theme by registering support
|
|
* for various features in WordPress, such as a custom background and a navigation menu.
|
|
*
|
|
* 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.
|
|
*
|
|
* For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
