 This package provides a little pomodoro timer in the mode-line.

 After importing into your Emacs configuration, redtick shows a little
 red tick (✓) in the mode-line. When you click on this tick, redtick
 starts a pomodoro timer.

 The Pomodoro Technique involves working in 25 minute intervals,
 separated by 5 minute breaks, with a longer break after every four
 intervals.
