+# ==== Purpose ====
+#
+# Waits until the slave SQL thread has been synced, i.e., all events
+# have been copied over to slave.  This is like mtr's built-in command
+# sync_slave_with_master, but more flexible (e.g., you can set a
+# custom timeout and you can force it to use GTIDs instead of filename
+# and offset).
+#
+#
+# ==== Usage ====
+#
+# [--let $sync_slave_connection= <connection_name>]
+# [--let $use_gtids= 1]
+# [--let $slave_timeout= NUMBER]
+# [--let $rpl_debug= 1]
+# --source include/sync_slave_io_with_master.inc
+#
+# Must be called on the master. Will change connection to the slave.
+#
+# Parameters:
+#
+#   $use_gtids
+#     If set, uses GTIDs instead of filename and offset for positions.
+#
+#   $sync_slave_connection
+#     By default, this script switches connection to 'slave'. If
+#     $sync_slave_connection is set, then '$sync_slave_connection' is
+#     used instead of 'slave'.
+#
+#   $slave_timeout
+#      See include/wait_for_slave_param.inc.
+#
+#   $rpl_debug
+#      See include/rpl_init.inc
