should be easier to differentiate between qst logs and command output
now as well.

go/qst.go

var justDetect = flag.Bool("detect", false, "detect the project type and exit")
func main() {
	log.SetFlags(log.Ldate | log.Ltime | log.Lshortfile)
	flag.Usage = func() {
		fmt.Fprintf(os.Stderr, "Usage: %s <file>\n\n", os.Args[0])
		flag.PrintDefaults()
	r.started = true
	go func() {
		for {
			log.Printf("running %s", r.shellCmd)
			log.Printf("[runner] starting command")
			r.cmd = exec.Command("sh", "-c", r.shellCmd)
			r.cmd.Stderr = os.Stderr
			r.cmd.Stdout = os.Stdout
			} else {
				result = r.cmd.ProcessState

			log.Printf("%s finished: %s", r.shellCmd, result)
			log.Printf("[runner] finished: %s", result)
			time.Sleep(*delay)
			if !r.restarting && !r.autoRestart {
