Podget is a simple podcast aggregator optimized for running as a scheduled background job (i.e. cron). It features support for downloading podcasts from RSS & ATOM XML feeds, for sorting the files into folders & categories, for importing URLs from iTunes PCAST files & OPML lists automatic M3U & ASX playlist creation, and automatic cleanup of old files. It also features automatic UTF-16 conversion for podcasts hosted on MS Windows servers.
As of version 0.8.5, we added a few options to be sure dependencies are installed when running on Mac OS X.
