89cf6a70 40=head1 HOW TO USE
41
42 This is a test of the replicated storage system. This will work in one of
43 two ways, either it was try to fake replication with a couple of SQLite DBs
44 and creative use of copy, or if you define a couple of %ENV vars correctly
45 will try to test those. If you do that, it will assume the setup is properly
46 replicating. Your results may vary, but I have demonstrated this to work with
47 mysql native replication.
