+##### RULES OF THUMB TO PRESERVE THE SYSTEMATICS OF THE PS TEST CASES #####
+#
+# 0. You  don't have the time to 
+#    - read and pay attention to these rules of thumb
+#    - accept that QA may move your test case to a different place
+#      (I will not change your code!!) .
+#    Please append your test case to
+#        t/ps.test
+#
+# 1. You have more time and want to get as much value from you test case as
+#    possible. Please try to make the following decisions:
+#
+#    Will the execution or result of the sub test case depend on the
+#    properties of a storage engine ?
+#
+#      NO   --> alter t/ps_1general.test (Example: Command with syntax error)
+#               If you need a table, please try to use
+#               t1               - very simple table
+#               t_many_col_types - table with nearly all available column types
+#               whenever possible.
+#
+#               The structure and the content of these tables can be found in
+#               include/ps_create.inc  CREATE TABLE ...
+#               include/ps_renew.inc   DELETE all rows and INSERT some rows
+#
+#               Both tables are managed by the same storage engine.
+#               The type of the storage engine is stored in the variable 
+#               '$type' .  In ps_1general.test $type is set to 'MYISAM'.
+#    
+#               Please feel free to source ps_create.inc or ps_renew.inc
+#               whenever you think it helps. But please restore the original
+#               state of these tables after your tests, because the following
+#               statements may depend on it.
+#
+#      YES
+#       |
+#       |
+#    Is it possible to apply the sub test case to all table types ?
+#      YES  --> alter include/ps_query.inc   (for SELECTs)
+#                     include/ps_modify.inc  (for INSERT/UPDATE/DELETE)
+#                     include/ps_modify1.inc (also for INSERT/UPDATE/DELETE,

+#               Please try to find an appropriate place within the file.
