-# This file implements regression tests for SQLite library.  The

-# This file was created when support for optimizing IS NULL phrases
-# was added.  And so the principle purpose of this file is to test
-# that IS NULL phrases are correctly optimized.  But you can never
-# have too many tests, so some other tests are thrown in as well.
