# ==== Purpose ====
#
# Display the delay state of the SQL thread.
#
# ==== Usage ====
#
# --let $verbose_delayed_slave_state= [0|1]
# --source extra/rpl_tests/show_delayed_slave_state.inc
#
# By default, the output is normalized so that it does not depend on
# exact timing or exact binlog positions. If
# $verbose_delayed_slave_state is set, then it outputs exact times and
# binlog positions. This can be useful for debugging.
