|
|
*
|
|
* When using a child theme (see http://codex.wordpress.org/Theme_Development and
|
|
* http://codex.wordpress.org/Child_Themes), you can override certain functions

|

* Functions that are not pluggable (not wrapped in function_exists()) are instead attached
|

* to a filter or action hook.
