README

1. Place itunes-current-track-tmux.sh somewhere nice.
2. Make it executable by doing "chmod +x itunes-current-track-tmux.sh"
3. Place the contents of .tmux.conf inside your own .tmux.conf
4. Adjust the path in this line to match where you placed the shell script:
 set -g status-right '#[fg=colour245]⮃ %R ⮃ %d %b #[fg=colour254,bg=colour234,nobold]#(~/Documents/AppleScripts/itunes-current-track-tmux.sh)⮂#[fg=colour16,bg=colour254,bold] #h '
5. Restart tmux with "killall -9 tmux"
6. Fire up iTunes, tmux, and enjoy! Screenshot here: http://f.fhl.gd/En8X
