28 This is a test of the replicated storage system. This will work in one of
29 two ways, either it was try to fake replication with a couple of SQLite DBs
30 and creative use of copy, or if you define a couple of %ENV vars correctly
31 will try to test those. If you do that, it will assume the setup is properly
32 replicating. Your results may vary, but I have demonstrated this to work with
33 mysql native replication.
