+/**
+ * TEACache class
+ *
+ * TEACache implements a cache application module based on {@link http://eaccelerator.net/ eAccelerator}.
+ *
+ * By definition, cache does not ensure the existence of a value
+ * even if it never expires. Cache is not meant to be an persistent storage.
+ *
+ * To use this module, the eAccelerator PHP extension must be loaded and enabled
+ *
+ * Please note that as of v0.9.6, eAccelerator no longer supports data caching.
+ * This means if you still want to use this component, your eAccelerator should be of 0.9.5.x or lower version.
+ *
+ * Some usage examples of TEACache are as follows,
+ * <code>
+ * $cache=new TEACache;  // TEACache may also be loaded as a Prado application module
+ * $cache->init(null);
+ * $cache->add('object',$object);
+ * $object2=$cache->get('object');
+ * </code>
+ *
+ * If loaded, TEACache will register itself with {@link TApplication} as the
+ * cache module. It can be accessed via {@link TApplication::getCache()}.
+ *
+ * TEACache may be configured in application configuration file as follows
+ * <code>
+ * <module id="cache" class="System.Caching.TEACache" />
+ * </code>
