*
- * The template.php file is one of the most useful files when creating or
- * modifying Drupal themes. You can add new regions for block content, modify or
- * override Drupal's theme functions, intercept or make additional variables
- * available to your theme, and create custom PHP logic. For more information,
- * please visit the Theme Developer's Guide on Drupal.org:
- * http://drupal.org/theme-guide
+ * The base Zen theme is designed to be easily extended by its sub-themes. You
+ * shouldn't modify this or any of the CSS or PHP files in the root zen/ folder.
+ * See the online documentation for more information:
+ * http://drupal.org/documentation/theme/zen
