-# WARNING: Log rotating should not be implemented here.
-#          SQLite does not access database only by file descriptor,
-#          and an OperationalError exception would be raised if a log is emitted
-#          between a rename and a reopen.
-#          Fortunately, SQLite allow multiple process to access the same DB,
-#          so an external tool should be able to dump and empty tables.
