// netstring format serialization library.
//
// This is implementation of netstring
// (http://cr.yp.to/proto/netstrings.txt) format for binary string
// serialization.
//
//   buf := bytes.NewBuffer(nil)
//   w := netstring.NewWriter(buf)
//   w.Write([]byte("hello")) // buf contains "5:hello,"
//   w.Write([]byte("world!")) // buf contains "5:hello,6:world!,"
//   r := netstring.NewReader(buf)
//   size, err := r.Iter() // size is 5
//   r.Discard() // discard (skip) current netstring ("hello")
//   size, err = r.Iter() // size is 6
//   out := make([]byte, size)
//   r.Read(out) // out contains "world!" bytes
//
// Pay attention that netstring uses bufio for Reader and Writer.
