package main

	"time"

const (
	duration      = 30 * time.Second
	interval_time = 5 * time.Second
)

	ticker := time.NewTicker(interval_time)

	go func() {
		for {
			select {
			case <-ticker.C:
				log.Println("\tdoing somethig.....")
			case <-quit:
				ticker.Stop()
				return
			}
		}
	}()
	log.Printf("Repeating a task each %v during %v.", interval_time, duration)
	<-time.After(time.Duration(duration))
	log.Println("End")
