11: # This file implements regression tests for SQLite library. The
12: # focus of this file is testing that the current version of SQLite
13: # is capable of reading and writing databases created by previous
14: # versions, and vice-versa.
15: #
16: # To use this test, old versions of the testfixture process should be
17: # copied into the working directory alongside the new version. The old
18: # versions should be named "testfixtureXXX" (or testfixtureXXX.exe on
19: # windows), where XXX can be any string.
20: #
21: # This test file uses the tcl code for controlling a second testfixture
22: # process located in lock_common.tcl. See the commments in lock_common.tcl
23: # for documentation of the available commands.
