Why: * The old way of handling arguments could make it difficult to make non-breaking changes because to be able to handle more arguments than the '--above' argument, the logic would need to be heavily refactored and demand restrictions on argument order. This change addresses the need by: * Parse arguments in a cleaner way * Make the command more future proof with respect to arguments Notable change is the synopsis. Please the see man page.
