Usage: $0 [MYSQL_OPTIONS]
You have to specify all options needed by "mysql" as if you had started
the MySQL command line client directly (including the name of the
database to operate on). The MySQL user used has to have enough
privileges to do all necessary operations (among others CREATE, ALTER,
DROP, UPDATE, INSERT, DELETE).
You might need to enter the mysql password multiple times if you
specify the -p option.
