+APCu
+~~~~

+In order to use the APCu cache driver you must have it compiled and
+enabled in your php.ini. You can read about APCu
+`in the PHP Documentation <http://us2.php.net/apcu>`_. It will give
+you a little background information about what it is and how you
+can use it as well as how to install it.
+
+Below is a simple example of how you could use the APCu cache driver
+by itself.
