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.
