+=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.
