+   * This can be valuable to be able to cache a view and still have some level
+   * of dynamic output. In an ideal world, the actual output will include HTML
    * comment based tokens, and then the post process can replace those tokens.

    * Example usage. If it is known that the view is a node view and that the
    * primary field will be a nid, you can do something like this:
-   *
-   * <!--post-FIELD-NID-->
+   * @code
+   *   <!--post-FIELD-NID-->
+   * @endcode
    *
    * And then in the post render, create an array with the text that should
    * go there:
    *
-   * strtr($output, array('<!--post-FIELD-1-->', 'output for FIELD of nid 1');
+   * @code
+   *   strtr($output, array('<!--post-FIELD-1-->', 'output for FIELD of nid 1');
+   * @endcode
    *
    * All of the cached result data will be available in $view->result, as well,
    * so all ids used in the query should be discoverable.
