  12  // your older installation to the current version.

  15  // will tell you what you need to do.
  16  //
  17  // The commands in here will all be database-neutral,
  18  // using the methods of database_manager class
  19  //
  20  // Please do not forget to use upgrade_set_timeout()
  21  // before any action that may take longer time to finish.
