Use iTunes on Windows to control what's playing in XBMC

intune.rb

# Assumes that your Music library is shared out
# and XBMC accesses it via Windows filesharing.
#
# Install the xbmc gem: gem install xbmc (may also need to run 'gem sources -a http://gemcutter.org')
# Edit the variables below and save as intune.rb
# Run 'ruby intune.rb'.
