"""Display and run a Pomodoro timer.
Left click to start timer, left click again to pause.
Right click will cancel the timer.

Parameters:
    * pomodoro.work: The work duration of timer in minutes (defaults to 25)
    * pomodoro.break: The break duration of timer in minutes (defaults to 5)
    * pomodoro.format: Timer display format with '%m' and '%s' for minutes and seconds (defaults to '%m:%s')
      Examples: '%m min %s sec', '%mm', '', 'timer'
    * pomodoro.notify: Notification command to run when timer ends/starts (defaults to nothing)
      Example: 'notify-send 'Time up!''. If you want to chain multiple commands,
      please use an external wrapper script and invoke that. The module itself does
      not support command chaining (see https://github.com/tobi-wan-kenobi/bumblebee-status/issues/532
      for a detailed explanation)

If you want to change the work and break duration, just change variables in the beginning of the pomodoro.py file.
