+/**
+ * View script integration
+ *
+ * Zend_Controller_Action_Helper_ViewRenderer provides transparent view
+ * integration for action controllers. It allows you to create a view object
+ * once, and populate it throughout all actions. Several global options may be
+ * set:
+ *
+ * - noController: if set true, render() will not look for view scripts in
+ *   subdirectories named after the controller
+ * - viewSuffix: what view script filename suffix to use
+ *
+ * The helper autoinitializes the action controller view preDispatch(). It
+ * determines the path to the class file, and then determines the view base
+ * directory from there. It also uses the module name as a class prefix for
+ * helpers and views such that if your module name is 'Search', it will set the
+ * helper class prefix to 'Search_View_Helper' and the filter class prefix to ;
+ * 'Search_View_Filter'.
+ *
+ * Usage:
+ * <code>
+ * // In your bootstrap:
+ * Zend_Controller_Action_HelperBroker::addHelper(new Zend_Controller_Action_Helper_ViewRenderer());
+ *
+ * // In your action controller methods:
+ * $viewHelper = $this->_helper->getHelper('view');
+ *
+ * // Don't use controller subdirectories
+ * $viewHelper->setNoController(true);
+ *
+ * // Specify a different script to render:
+ * $this->_helper->viewRenderer('form');
+ *
+ * </code>
