 | 
						|
 | 
						|
   Script checks (and reorganizes) all tables of all databases by executing MySQL
 | 
						|
   command 'OPTIMIZE TABLE'.
 | 
						|
 | 
						|
   If a database is given at the command line, only tables of that database
 | 
						|
   will be checked.
 | 
						|
 | 
						|
   If a check on a table fails, MySQL command 'REPAIR TABLE' will be executed on
 | 
						|
   that table.

						|
