anchor.diff:  
   For Java code (Kill Bill and Java plugins), we publish a `killbill-flyway.jar` binary which is a wrapper around the `flyway` utility and exposes a `dryRunMigrate` command. Simply run it against your production database (read-only credentials are sufficient) to get the raw SQL.
   
  +Usage example:
  +
  +```
  +java -jar killbill-flyway.jar -locations=filesystem:XXX dryRunMigrate
  +```

   ==== Ruby
   
   For Ruby code, we provide a `killbill-migration` script with the `killbill` gem (JRuby is recommended, see our http://docs.killbill.io/0.16/payment_plugin.html#_building_ruby_plugins[installation instructions]).
