+=item --record_log_pos log-pos-table
+
+Just before the database files are copied, update the record in the
+log-pos-table from the values returned from "show master status" and
+"show slave status". The master status values are stored in the
+log_file and log_pos columns, and establish the position in the binary
+logs that any slaves of this host should adopt if initialised from
+this dump.  The slave status values are stored in master_host,
+master_log_file, and master_log_pos, and these are useful if the host
+performing the dump is a slave and other sibling slaves are to be
+initialised from this dump.
+
+The name of the log-pos table should be supplied in database.table format.
