		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.
