Python, podcasts and bikes.

In preparation, the PC for the role of the home server is constantly trying to give up all sorts of gui. Hands reached the podcasts. Hpodder did not cause delight, broke the tags in the files. That was written my bike in python.

It turned out two files.
Settings file.

download_dir = /home/bobathecar/scriptForPodcast/episodes/
download_episodes = 1

[podcasts]
budam = budam.rpod.ru/rss.xml

Umputun = feeds.feedburner.com/Umputun

iAnime = i-anime.rpod.ru/rss.xml
Radio-T = feeds.feedburner.com/Radio-t

The name will be written in the artist tag.
and the script itself

As a result, my cycling shakes a specified number of recent episodes of podcasts. Renames files, and rewrites tags. Finally, my mp3 player will be cleaned up and podcasts will always be where I expect to be.
