  19   * Folder module upgrade code
  20   *
  21   * This file keeps track of upgrades to
  22   * the resource module
  23   *
  24   * Sometimes, changes between versions involve
  25   * alterations to database structures and other
  26   * major things that may break installations.
  27   *
  28   * The upgrade function in this file will attempt
  29   * to perform all the necessary actions to upgrade
  30   * your older installation to the current version.
  31   *
  32   * If there's something it cannot do itself, it
  33   * will tell you what you need to do.
  34   *
  35   * The commands in here will all be database-neutral,
  36   * using the methods of database_manager class
  37   *
  38   * Please do not forget to use upgrade_set_timeout()
  39   * before any action that may take longer time to finish.
  40   *
