}

func main() {
	logDir := "./logs"
	l, err := clog.NewLog(logDir)
	if err != nil {
		fmt.Printf("failed to create a new log: %v\n", err)
		os.Exit(1)
	}

	data := convertStringToBytes("Hello World!")
	err = l.Write(data)
	if err != nil {
		fmt.Printf("failed to write to log: %v\n", err)
		os.Exit(1)
	}

	offset := int64(0)
	data, err = l.Read(offset)
	if err != nil {
		fmt.Printf("failed to read from log: %v\n", err)
		os.Exit(1)
	}
	fmt.Printf("Fetched the following message at offset %d: %s\n", offset, string(data))
