This is a web UI and audio player for gpodder.
The idea is that gpodder runs on a server with a job or service periodically issuing a gpo update; gpo download command.
Then this application reads the gpodder database so that a web page can list the episodes and select one to be played with jPlayer.
In production nginx will be used to proxy requests to the webapp, serve the handful of static files, and serve the MP3 files themselves (on a separate subdomain).
