  23. # Usage: You can run this file with the command line option -s, -p or
  24. # -t, or any combination, for example -sp, -ps, -tp, -tps. The
  25. # behaviour is as follows.
  26. #
  27. # -s: Rotates the screen by 90 degrees. Depending on your desktop
  28. # environment, the stylus input might get rotated or not.
  29. #
  30. # -p: Makes the stylus have the same rotation as the the screen.
  31. #
  32. # -t: Makes the trackpoint have the same rotation as the the screen.
  33. #
  34. # The script requires xrandr and xsetwacom.
