Detect whether Go program is run from cmd.exe

I’m having a hard time searching on this one, and I have very limited knowledge of Windows systems.

How can I tell, with reasonable certainty, if the program was run from, say, Windows Explorer (by double-clicking the icon) – or anything that’s not cmd.exe? Any Windows gurus know some way to do this within a Go program?

	if runtime.GOOS == "windows" {
		if mousetrap.StartedByExplorer() {
			fmt.Println("Don't double-click ngrok!")
			fmt.Println("You need to open cmd.exe and run it from the command line!")
			time.Sleep(5 * time.Second)
			os.Exit(1)

That’s PERFECT. Never would have found that on my own… Thanks!
