I didnt like how bashpodder dumped everything in the one
directory, so I modified it to  create subdirectories for each feed. I
had to use a little bit of python, because I have little idea with
bash, but dont worry, no extra modules needed, just a plain python
install.
Because the rss feeds generally don't have a name in them suitable for
a directory name, it has to be set manually. The first config file
~/.bashpodder/bp.conf has feeds, second ~/.bashpodder/bpd.conf has
directory names. The name in the directory config has to correspond
with the feed in the feed config,

eg http://www.thelinuxlink.net/tllts/tllts.rss first in the feed list,
and Linux Link Tech Show first in the directory list. Take a look at
the script and my config's above.
