+/**
+ * CPradoViewRenderer implements a view renderer that allows users to use a template syntax similar to PRADO templates.
+ *
+ * To use CPradoViewRenderer, configure it as an application component named "viewRenderer" in the application configuration:
+ * <pre>
+ * array(
+ *     'components'=>array(
+ *         ......
+ *         'viewRenderer'=>array(
+ *             'class'=>'CPradoViewRenderer',
+ *         ),
+ *     ),
+ * )
+ * </pre>
+ *
+ * CPradoViewRenderer allows you to write view files with the following syntax:
+ * <pre>
+ * // PHP tags:
+ * <%= expression %>
+ * // <?php echo expression ?>
+ * <% statement %>
+ * // <?php statement ?></li>
+ *
+ * // component tags:
+ * <com:WigetClass name1="value1" name2='value2' name3={value3} >
+ * // <?php $this->beginWidget('WigetClass',
+ * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?>
+ * </com:WigetClass >
+ * // <?php $this->endWidget('WigetClass'); ?>
+ * <com:WigetClass name1="value1" name2='value2' name3={value3} />
+ * // <?php $this->widget('WigetClass',
+ * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3)); ?>
+ *
+ * // cache tags:
+ * <cache:fragmentID name1="value1" name2='value2' name3={value3} >
+ * // <?php if($this->beginCache('fragmentID',
+ * // array('name1'=>"value1", 'name2'=>'value2', 'name3'=>value3))): ?>
+ * </cache:fragmentID >
+ * // <?php $this->endCache('fragmentID'); endif; ?>
+ *
+ * // clip tags:
+ * <clip:clipID >
+ * // <?php $this->beginClip('clipID'); ?>
+ * </clip:clipID >
+ * // <?php $this->endClip('clipID'); ?>
+ *
+ * // comment tags:
+ * <!--- comments --->
+ * // the whole tag will be stripped off
+ * </pre>
