+# The following tests ensure that if user-defined variables are used in SF/Triggers 
+# that they are replicated correctly. These tests should be run in both SBR and RBR 
+# modes.
+
+# This test uses a procedure that inserts data values based on the value of a 
+# user-defined variable. It also has a trigger that inserts data based on the 
+# same variable. Successful test runs show that the @var is replicated 
+# properly and that the procedure and trigger insert the correct data on the 
+# slave.
+#
+# The test of stored procedure was included for completeness. Replication of stored 
+# procedures was not directly affected by BUG#20141.
