Armangil's vodcatcher is a video podcast (or vodcast) client for the command
line. It provides several download strategies (new shows only, back-catalog
allowed, etc), supports BitTorrent, offers cache management, and generates
playlists for video player applications.

This application accepts one or more feeds (RSS or Atom) or subscription lists
(OPML or iTunes PCAST) as argument, in the form of URLs or filenames.
Alternatively, it tries to read one such document from the standard input.
