A node library for encoding and decoding bencoded data,
according to the BitTorrent specification.
from Wikipedia:
Bencode (pronounced like B encode) is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data.
It supports four different types of values:
Bencoding is most commonly used in torrent files. These metadata files are simply bencoded dictionaries.

var data = {

integer: 12345,
dict: {
key: 'This is a string within a dictionary'
},
list: [ 1, 2, 3, 4, 'string', 5, {} ]
}

Automagically convert bytestrings to strings:
var result = bencode.decode( data, 'utf8' )
{
string: 'Hello World',
integer: 12345,
dict: {
key: 'This is a string within a dictionary'
},
list: [ 1, 2, 3, 4, 'string', 5, {} ]
}
