Invoking help with a flag other than -h

[shueybubbles]

My app has a backward compatibility reason to reserve -h for other purposes. I see kong.go hard codes h as the default value so I'd need to replace it with my own flag and set the NoDefaultHelp() option in Parse. If I do that, how does my flag implementation invoke the default help printer?

it figures I find it right after posting.

Is this the most effective approach?

	Help                        bool              `short:"?" help:"show syntax summary"`

	k, err := kong.New(&args, kong.NoDefaultHelp())
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	ctx, err := k.Parse(os.Args[1:])
	if err != nil {
		fmt.Println(err.Error())
		os.Exit(1)
	}
	if args.Help {
		_ = kong.DefaultHelpPrinter(kong.HelpOptions{}, ctx)
		os.Exit(0)
	}

c := kong.Parse
c.PrintUsage is probably even better.
I need more coffee?

From memory there's a way to do this already - use kong.New(), then modify the existing help flag in the model to remove the short flag.
