  9. * This can be used to skip running an installation task when certain
  10. * conditions are met, even though the task may still show on the list of
  11. * installation tasks presented to the user. For example, the Drupal installer
  12. * uses this flag to skip over the database configuration form when valid
  13. * database connection information is already available from settings.php. It
  14. * also uses this flag to skip language import tasks when the installation is
  15. * being performed in English.
