database' or 'set ..' command to stdout. A SQL query may contain
newlines. This is useful to find things in a MySQL update log.

--help or --Information
Shows this help
--regexp=#
Print queries that matches this.
--start_row=#
Start output from this row (first row = 1)
--skip-use-db
Don\'t include \'use database\' commands in the output.
--rows=#
Quit after this many rows.
Example:
$0 --regexp "problem_table" < update.log
$0 --regexp "problem_table" update-log.1 update-log.2
EOF
exit(0);
