+   * For the simplest use:
+   * @code
+   *   $output = $view->executeDisplay('default', $args);
+   * @endcode
+   *
+   * For more complex usages, a view can be partially built:
+   * @code
+   *   $view->setArguments($args);
+   *   $view->build('default'); // Build the query
+   *   $view->preExecute(); // Pre-execute the query.
+   *   $view->execute(); // Run the query
+   *   $output = $view->render(); // Render the view
+   * @endcode
+   *
+   * If short circuited at any point, look in $view->build_info for
+   * information about the query. After execute, look in $view->result
+   * for the array of objects returned from db_query.
+   *
+   * You can also do:
+   * @code
+   *   $view->setArguments($args);
+   *   $output = $view->render('default'); // Render the view
+   * @endcode
+   *
+   * This illustrates that render is smart enough to call build and execute
+   * if these items have not already been accomplished.
+   *
+   * Note that execute also must accomplish other tasks, such as setting page
+   * titles, and generating exposed filter data if necessary.
