#% SYNOPSIS
#+    rotate_display.sh [normal/right/left]
#%
#% DESCRIPTION
#%    This script looks for all displays connected and rotates the first one from the list.
#%
#%    It takes one mandatory parameter. The direction of the rotation.
#%    Based on xrandr. From xrandr manual:
#%    "Rotation can be one of 'normal', 'left', 'right' or 'inverted'. This causes the output contents to be
#%    rotated in the specified direction. 'right' specifies a clockwise rotation of the picture and  'left'
#%    specifies a counter-clockwise rotation."
