+# This file implements regression tests for SQLite library.  The
+# focus of this file is testing the LIKE and GLOB operators and
+# in particular the optimizations that occur to help those operators
+# run faster and that those optimizations work correctly when there
+# are both strings and blobs being tested.
+#
+# Ticket 05f43be8fdda9fbd948d374319b99b054140bc36 shows that the following
+# SQL was not working correctly:
+#
+#     CREATE TABLE t1(x TEXT UNIQUE COLLATE nocase);
+#     INSERT INTO t1(x) VALUES(x'616263');
+#     SELECT 'query-1', x FROM t1 WHERE x LIKE 'a%';
+#     SELECT 'query-2', x FROM t1 WHERE +x LIKE 'a%';
+#
+# This script verifies that it works right now.
