Podcast backup script
"""
Podcast backup script
Parses an RSS feed from SOURCE_FILE and download all items to
DESTINATION_PATH. Downloads are done in parallel, for
PARALLEL_COUNT downloads at the time.
How to use
----------
1. Set DESTINATION_PATH. Make sure the folder exists on your
file system.
2. Save the source file (RSS or Atom) on your computer and
update SOURCE_FILE if needed.
3. Alter PARALLEL_COUNT for your needs. Higher number will
decrease total time for this script to be done, but will
increase net traffic.
4. Run script in a python intepreter, 3.7 is recommended.
This script was written by Anders Ytterström in October 2019.
