\033[1mUsage:\033[m
$(basename $0) [-h|-v] [DB-Name]
\033[1mDescription\033[m
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.
\033[1mOptions\033[m
-h
Prints this help
-v
Verbose output if running on a terminal.
