# Test of replication of stored procedures (WL#2146 for MySQL 5.0)
# Modified by WL#2971.

# Note that in the .opt files we still use the old variable name
# log-bin-trust-routine-creators so that this test checks that it's
# still accepted (this test also checks that the new name is
# accepted). The old name could be removed in 5.1 or 6.0.
