26 | =head1 HOW TO USE |
27 | |
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. |
