public interface LiquibaseCommand<T extends CommandResult>

Commands are higher-level functions. They may execute multiple Changes and usually interact with the outside world. Commands are different from Actions in that they implement end-user functionality rather than small pieces of logic. We package functionaly as commands so that the command line interface as well as other integrations can all use the same business logic.
