+Used for producing a dump file from a replication slave server that can be used to set up another slave server 
+with the same master\&. Causes the binary log position and filename of the master to be appended to the dumped 
+data output\&. Setting the value to 1 (the default) will print it as a CHANGE MASTER command in the dumped data 
+output; if set to 2, that command will be prefixed with a comment symbol\&. This option will turn 
+\-\-lock\-all\-tables on, unless \-\-single-transaction is specified too (in which case a global read lock is only 
+taken a short time at the beginning of the dump \- don't forget to read about \-\-single-transaction below)\&. In 
+all cases any action on logs will happen at the exact moment of the dump\&. Option automatically turns 
+\-\-lock\-tables off\&. Using this option causes mysqldump to stop the slave SQL thread before beginning the dump, 
+and restart it again after completion\&.
