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