# This is an example script that sends external metadata to streamripper.
# It implements an external program that:
#   1) Fetches a web page
#   2) Searches the web page for the artist and title information
#   3) Sends the information to streamripper
# 
# To invoke the script, do this:
#    streamripper URL -E "perl fetch_external_metadata.pl META_URL"
#
# This assumes that META_URL is the URL with the artist/title information
# 
# You will need perl and LWP::Simple installed to run this script. 
# On unix, you install LWP::Simple as root, like this:
#    perl -MCPAN -e 'install LWP::Simple';
# On windows, LWP::Simple is included in the ActiveState perl distribution.
#
# This script is in the public domain. You are free to use, modify and 
# redistribute without restrictions.
