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