-- This script converts any old privilege tables to privilege tables suitable
-- for MySQL 4.0.

-- You can safely ignore all 'Duplicate column' and 'Unknown column' errors"
-- because these just mean that your tables are already up to date.
-- This script is safe to run even if your tables are already up to date!

-- On unix, you should use the mysql_fix_privilege_tables script to execute
-- this sql script.
-- On windows you should do 'mysql --force mysql < mysql_fix_privilege_tables.sql'
