title: Reading the fileset from a torrent
body: <p>I want to (quickly) put a program/script together to read the fileset from a .torrent file. I want to then use that set to delete any files from a specific directory that do not belong to the torrent.</p>
  
  <p>Any recommendations on a handy library for reading this index from the .torrent file? Whilst I don't object to it, I don't want to be digging deep into the bittorrent spec and rolling a load of code from scratch for this simple purpose.</p>
  
  <p>I have no preference on language.</p>
