This file creates a default cache configuration using the most optimized adapter available, and
uses it to provide default caching for high-overhead operations.

{{{

use lithium\storage\Cache;
use lithium\core\Libraries;
use lithium\action\Dispatcher;
use lithium\storage\cache\adapter\Apc;

if (PHP_SAPI === 'cli') {
	return;
}

If APC is not available and the cache directory is not writeable, bail out. This block should be
removed post-install, and the cache should be configured with the adapter you plan to use.
