  3. Alarm script
  4. ============

  8. A simple alarm script that plays a list of MP3s at a given time.
  9. Very useful if you leave your computer switched on during the night.
  10. Usage:
  11. ------
  12. ./alarm.py -p
  13. Play music. First do this to adjust volume! If the volume is low,
  14. you won't hear it in the morning.
  15. ./alarm.py -t 7h15
  16. Set alarm time. The format is HhM, where H is the hour (24-hour system),
  17. M is the minute, 'h' is the separator.
  18. ./alarm.py
  19. Set alarm with the default time. In my case it's 6h55.
