PiddlePodder
Piddlepodder is a podcatching client written in Perl. It is based off of the simplicity of bashpodder with a few added features. It downloads podcasts from a list of XML feeds, and puts them into a download directory by date. No effort is made to copy the resulting files to an iPod, nor will this application interface with a directory. It's just a simple podcatcher.
That's it.
Piddlepodder offers the ability to mark the set of podcasts as current (catch up). This is handy for first-time users who would otherwise be stuck downloading every show (sometimes since the beginning of the podcast) which can lead to hefty download times and large amounts of disk space.
