# Modified by bruce@raba.com to sort feeds into subdirectories and
# generate hierarchical playlist suitable for windows-oriented mp3
# players (like my Iriver H120)

# Improved by Michael.Strecke@gmx.de to correct problem with empty
# "dir" in the bp.conf file and proper handling of spaces in dir name


# Make script crontab friendly:
cd $(dirname $0)

# datadir is the directory you want podcasts saved to:
datadir=${HOME}/Podcasts
datestr=$(date +%Y-%m-%d)

# Check for and create datadir if necessary:
if test ! -d $datadir
        then
        mkdir -p $datadir
fi

# Delete any temp file:
rm -f temp.log

# Read the bp.conf file and wget any url not already in the podcast.log file:
while read podcast
	do
	feed=$(echo $podcast | cut -d" " -f1)
	dir=$(echo $podcast | cut -d" " -s -f2-)
