* Sometimes, changes between versions involve

|
* alterations to database structures and other
|
|
* major things that may break installations.
|
|

|
|
* The upgrade function in this file will attempt

*
|
|
* If there's something it cannot do itself, it
|
|
* will tell you what you need to do.
|
|
*
|
|
* The commands in here will all be database-neutral,
|
|
* using the methods of database_manager class
|
|
*
|
|
* Please do not forget to use upgrade_set_timeout()
|
|
* before any action that may take longer time to finish.
