Zen 6.x-2.0 @TODO
-----------------
- #: Add fix to auto-correct tabs broken by contrib modules
- #: Display "edit menu" only when Menu block is displaying menu.module links
- * confirm all the variables of every tpl are documented.
- #341140: drupal_get_filename() is broken in Drupal 6. When that is fixed,
  replace _zen_path() with drupal_get_path('theme', 'zen').
