+
+# Test case for Bug#11230
+
+# The point of this test is to make sure that '#', '-- ' and '/* ... */'
+# comments, as well as empty lines, are sent from the client to the server.
+# This is to ensure better error reporting, and to keep comments in the code
+# for stored procedures / functions / triggers (Bug#11230).
+# As a result, be careful when editing comments in this script, they do
+# matter.
+#
+# Also, note that this is a script for **mysql**, not mysqltest.
+# This is critical, as the mysqltest client interprets comments differently.
