Pastis is a MacRuby script that fetches a torrent RSS feed and check against your filters to know if a torrent should be added to Transmission's queue.
MacRuby 0.6+ must be installed http://macruby.org
Transmission (http://www.transmissionbt.com/) must be installed and running. Remote access must also be enabled and password access is not yet supported.
All torrents get downloaded to a torrents folder (by default: ~/torrents/). A log of the downloaded files is saved in ~/.pastis-rsslog allowing to avoid downloading the same file twice, even if it's deleted. Torrents found needed to be added to the Transmission queue are saved in a different path, by default: "~/torrents/to_download".
