+# This file implements regression tests for SQLite library. Specifically,
+# it tests some compiler optimizations for SQL statements featuring
+# triggers:
+#
+#
+#
+
+# trigger9-1.* -   Test that if there are no references to OLD.* cols, or a
+#                  reference to only OLD.rowid, the data is not loaded.
+#
+# trigger9-2.* -   Test that for NEW.* records populated by UPDATE 
+#                  statements, unused fields are populated with NULL values. 
+#
+# trigger9-3.* -   Test that the temporary tables used for OLD.* references
+#                  in "INSTEAD OF" triggers have NULL values in unused 
+#                  fields.
