   11: # This file implements regression tests for SQLite library.  The
   12: # focus of this file is is verifying that a virtual table in the
   13: # TEMP database that is created and dropped within a transaction
   14: # is handled correctly.  Ticket #2994.
   15: #
   16: # Also make sure a virtual table on the right-hand side of an IN operator
   17: # is materialized rather than being used directly.  Ticket #3082.
