# ==== Purpose ====
#
# Verify that START SLAVE UNTIL replicates until the given binlog
# position but not longer.  Verify that START SLAVE UNTIL with various
# incorrect arguments gives an error.
#
# ==== Method ====
#
# On master, create a table and insert some rows.  On slave, START
# SLAVE UNTIL so that it reads one event at a time, and check the
# table and the slave status each time.
#
# Then, on slave, run START SLAVE UNTIL with incorrect arguments and
# verify that it gives an error.
#
# ==== Related bugs ====
