 # 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.
