The code doesn't just parse the protocol; it'll dump whatever the decoder can find. Sample output: info length 41470132 piece length 262144 name Halo2_E3.wmv pieces [159 SHA-1 values] announce http://news.gametab.com:6969/announce The format seems too simple in one way - fixed-size chunks. I'd expected some sort of recursive file definition. It's also too complex in one way - I don't think multi-files should be in a file transport mechanism. And really the `.torrent` file should be XML. But it's easy to criticize; BitTorrent is still awfully cool. tech • bittorrent 2003-05-27 01:27 Z Nelson's Weblog • tech • bittorrent
