Description:

A utility to automatically download enclosures and other objects
linked to from various types of RSS feeds.
videocasts, and torrents.

Features include:
- filtering using regular expressions and/or file size
- global, feed, and filter based download locations
- can run in the background (at least on GNU/Linux) like a daemon
- various logging and verbosity levels
- support for sites protected with cookies (LWP/MSIE/Mozilla/Safari/Firefox3)
- global and feed scan times
- respects 'ttl' tag in feeds that have them
- call custom functions after a download or after a scan of the feed
(episode advancement!)
- generates an RSS feed of what it has downloaded.

Because it is written in Python, it is highly cross-platform compatible.
It tries to be memory efficient, with reports of it functioning on
consumer routers. Minimal external dependencies help keep that a reality.
It became popular when people started using it in conjunction with
rTorrent for torrent broadcatching.
