It is meant to run on Linux and Mac OS X with different BitTorrent clients (for now, only Transmission is supported directly) and make it work in all Web browsers. It supports RSS feeds from a few torrent sites that offer TV shows. It can save torrent files in any folder, so any torrent client can pick it up. It can tell Transmission to save data in any folder. It can tell Transmission to stop when a certain ratio is reached. Authentication with Transmission is supported. Your own RSS feed can be added.
