+/**
+ * @package  Cache
+ *
+ * Cache settings, defined as arrays, or "groups". If no group name is
+ * used when loading the cache library, the group named "default" will be used.
+ *
+ * Each group can be used independently, and multiple groups can be used at once.
+ *
+ * Group Options:
+ *  driver   - Cache backend driver. Kohana comes with file, database, and memcache drivers.
+ *              > File cache is fast and reliable, but requires many filesystem lookups.
+ *              > Database cache can be used to cache items remotely, but is slower.
+ *              > Memcache is very high performance, but prevents cache tags from being used.
+ *
+ *  params   - Driver parameters, specific to each driver.
+ *
+ *  lifetime - Default lifetime of caches in seconds. By default caches are stored for
+ *             thirty minutes. Specific lifetime can also be set when creating a new cache.
+ *             Setting this to 0 will never automatically delete caches.
+ *
+ *  requests - Average number of cache requests that will processed before all expired
+ *             caches are deleted. This is commonly referred to as "garbage collection".
+ *             Setting this to 0 or a negative number will disable automatic garbage collection.
