+# ==== Purpose ====
+#
+# Issues STOP SLAVE on the current connection. Then waits until both
+# the IO and SQL threads have stopped, or until a timeout is reached.
+#
+# Please use this instead of 'STOP SLAVE', to reduce the risk of races
+# in test cases.
+#
+# This will fail if the slave IO or SQL thread has an error. If you
+# expect an error in the IO thread, use
+# include/wait_for_slave_io_error.inc and include/stop_slave_sql.inc.
+#
+#
+# ==== Usage ====
+#
+# [--let $rpl_only_running_threads= 1]
+# [--let $slave_timeout= NUMBER]
+# [--let $rpl_debug= 1]
+# --source include/stop_slave.inc
+#
+# Parameters:
+#   $rpl_only_running_threads
+#     By default, this script executes STOP SLAVE unconditionally.
+#     This generates a warnings if one or both slave threads are
+#     already stopped.  If $rpl_only_running_threads is set, this
+#     script checks which slave threads are running, and issues either
+#     STOP SLAVE, STOP SLAVE SQL_THREAD, STOP SLAVE IO_THREAD, or
+#     nothing.
+#
+#   $slave_timeout
+#     See include/wait_for_slave_param.inc
+#
+#   $rpl_debug
+#     See include/rpl_init.inc
