Machine Modification
If you want to modify an existing machine's definition, you can do so using the ModifyMachineEvent forge event or the
GTCEuStartupEvents.machineModification KJS event. It is fired right before a machine gets registered, so that
its builder is still accessible through the event.getBuilder() method. For examples of methods that machine builders
have, see Custom Machines.
For a full list of methods, see source.
