Tool to scan and download podcasts (podcatcher)

 Podcasting is a method of publishing radio-like programs on the
 Internet. Through podcasting, almost anyone can produce their own
 audio program, and publish episodes of it as often or as rarely as
 they like.
 .
 To listen to podcasts, you need a program to download the podcast's
 episodes from the Internet. Such a program is called a podcatcher
 (or sometimes a podcast aggregator). hpodder is this program.
 .
 hpodder's features include:
 .
 Convenient, easy to learn, and fast command-line interface. It's
 simple to do simple things, and advanced things are possible.
 .
 Automatic discovery of feed metadata
 .
 Full history database for accurate prevention of duplicate
 downloads and tracking of new episodes
 .
 Conversion tools to convert your existing feed list and history from
 other applications to hpodder. Supported applications and formats
 include: castpodder and ipodder.
 .
 Most operations can work fully automatically across your entire
 podcast database, or they can work manually.
 .
 Automatic updating of ID3 (v1 and v2) tags based on metadata in the
 podcast feed. This important feature is available through iTunes but
 is often missed by other podcatchers.
 .
 hpodder operations can be easily scripted or scheduled using regular
 operating system tools.
 .
 Fully customizable naming scheme for downloaded episodes, including a
 name collision detection and workaround algorithm.
 .
 Automatic support for appending .mp3 extensions to MP3 files that
 lack them.
 .
 Numerous database and history inquiry tools
 .
 Small, minimalist footprint
 .
 Power users and developers can interact directly with the embedded
 Sqlite3 database used by hpodder. The database has a simple schema
 that is developer-friendly.
 .
 Support for resuming interrupted downloads of podcasts
 .
 hpodder is SAFE and is designed with data integrity in mind from the
 beginning. It should be exceedingly difficult to lose a podcast
 episode, even in the event of a power failure.
