 -- This script updates the databases structure after migrating the data from
 -- version 1.9.0 (or version 1.9.*) to version 1.10.0
--- it is intended as a standalone script, however, because of the multiple
--- databases related difficulties, it should be parsed by a PHP script in
--- order to connect to and update the right databases.
--- There is one line per query, allowing the PHP function file() to read
--- all lines separately into an array. The xxMAINxx-type markers are there
--- to tell the PHP script which database we're talking about.
--- By always using the keyword "TABLE" in the queries, we should be able
--- to retrieve and modify the table name from the PHP script if needed, which
--- will allow us to deal with the unique-database-type installations
---
--- This first part is for the main database
