	// Simulate work
	time.Sleep(time.Second)

	return nil
}

func main() {

	worker := gwp.New(4)       // Create pool with specified number of workers

	worker.ShowProgress = true // Enable progress indicator
	worker.ShowSpeed = true    // Show processing speed in progress indicator
	worker.EstimateCount = 100 // Set total number on jobs to calculate ETA

	for i := 0; i < 100; i++ {
		n := i
		// Send job
		worker.Add(func() error {
			return f(n)
		})
	}

	// Wait all jobs to complete
	worker.CloseAndWait()
}
