+# Testing the behavior of 'PREPARE', 'DDL', 'EXECUTE' scenarios
+#
+# There are several subtests which are probably "superfluous" because a DDL
+# statement before the EXECUTE <prepared stmt handle> contained a keyword
+# or action (Example: Alter) which causes that all prepared statements using
+# the modified object are reprepared before execution.
+# Please do not delete these subtests if they disturb. Just disable them by
+# if (0)
+# {
+#    <tests to disable>
+# }.
+# There might be future optimisations of the server which decrease the amount
+# of unneeded reprepares or skip unneeded prepare steps and than these subtests
+# might become valuable.
+#    Example:
+#    Every preceding ALTER TABLE seems to cause a reprepare.
+#    But if the ALTER only changed the table comment ...
+#
+# Created: 2008-04-18 mleich
