RSS-torrent  is a command line broad-catching program that downloads selected torrents from an RSS or Twitter feed and puts them in a directory for your bittorrent program to download. The torrents to download are selected using filters that look at the name, size, and episode/season of the torrent. A mechanism is in place to prevent double downloads. RSS-torrent can even send an email when a new episode is found.
RSS-torrent is released unter GPLv3.
