+# This file implements regression tests for SQLite library.  The
+# focus of this file is is verifying that a virtual table in the
+# TEMP database that is created and dropped within a transaction
+# is handled correctly.  Ticket #2994.
+#
+# Also make sure a virtual table on the right-hand side of an IN operator
+# is materialized rather than being used directly.  Ticket #3082.
