-- Set these to match your monitor's portrait and landscape modes
-- For example, on my monitor, Landscape mode is 'Standard' (item 1 in the rotate menu)
-- On my monitor, Portrait mode is '90°' (item 2 in the rotate menu)
property rotationDirectionLandscape : 1 -- rotate menu item 1 (Standard)
property rotationDirectionPortrait : 2 -- rotate menu item 2 (90 degrees)

-- the "main" part of the script
-- activate System Preferences
tell application "System Preferences"
	activate
	set current pane to pane "com.apple.preference.displays"
	--reveal anchor "displaysDisplayTab" of pane "Displays"

-- get all the display preference pane windows
-- and rotate each corresponding display

-- this function gets a list of the display preferences windows.
-- needed if you have more than one display that you want to 
-- rotate.  Note: PowerBooks will not rotate their built-in
-- LCDs with this script.
