# YouTube playlist audio retreiver and iTunes-compliant podcast XML generation tool.

# This script will download each video file from the specified YouTube playlist, losslessly extract
# the audio, delete the video, and ultimately produce an iTunes-compliant podcast XML with the
# appropriate metadata, including chapter markers (if provided in the description). If you run the
# script again, only videos that haven't already been converted will be downloaded, allowing you to
# schedule the script to run as often as needed without stressing your internet connection or
# hard drive space. After generating the files and xml, you can easily host them on a local server
# in order to use them with iTunes or your favorite podcast aggregator -- but that's beyond this
# script's jurisdiction.

# I make no guarantees that any of this is correct. I calculated this
