trait Command extends DefaultCommandArgsApp with DelayedInit

Have a sealed trait extend this for its case class children to become commands.

Extends DelayedInit like App does.

Like with App, the remaining arguments are accessible with the method remainingArgs.

Example

sealed trait DemoCommand extends Command

case class First(
) extends DemoCommand {

  // ...

}

case class Second(
) extends DemoCommand {

  // ...

}

object MyApp extends CommandAppOf[DemoCommand]

In the example above, MyApp now has a main method, that accepts arguments like first a b or second c d. In the first case, it will create a First, and call its body (whose initialization is delayed thanks to delayed initialization). In the second case, it will create a Second instead, and call its body too.
