A colorful byobu script to notify your new mails and feeds

After delivering all the feeds to Maildirs by rssdrop, I also need a notification daemon in my byobu shell.

Byobu supports custom script and display the outputs in the bottom bar. And particularly, you can use colors in byobu script’s output!

Byobu is a frontend for screen or tmux.
