Some mystery still remains.

1. b is a byte from a buffer, and s is a string
s+=string(b)
and length(s) may not equal to length(buffer). 
why ??

2. shall I treat "pieces" differently ??


```golang
package main

import (
	"fmt"
	"io/ioutil"
	"log"

	"github.com/eminom/gobencode"
)

func main() {
	log.SetFlags(log.Lshortfile)
	filename := "1000.torrent"
	chunk, err := ioutil.ReadFile(filename)
	if err != nil {
		panic(err)
	}

	node, left := bencode.Scan(chunk)
	if len(left) > 0 {
		fmt.Printf("warning: still some left\n")
	}
	// bencode.PrintNode(node, 0)
	// fmt.Println()
	// bencode.PrintTorrent(node)

	rawFile := "1d94f21f346532936f3fea2171d067ef_165612kxnnibu2i7ibmml7.jpg"
	t := bencode.NewTorrent(node.AsMap()["info"].AsMap())

	verified, err := t.VerifyFile(rawFile)
	if err != nil {
		panic(err)
	}

	log.Printf("verified: %v", verified)
}

```
