xcalib for Debian
-----------------

  * IMPORTANT NOTICE FOR MULTI-MONITOR USERS:
    xcalib (0.9.dfsg1-1) is now built with XRandR support. If multiple
	displays (including mirroring) are used, xcalib may now only affect
	the primary display by default.
    
    The '-screen' option can specify the display. For example, to invert
    the second display:
    
      xcalib -screen 1 -invert -alter

You are very encouraged to read upstream README where it's explained ICC,
VCGT tags and monitor calibration and profiling philosophy.

If you are using xcalib on an Apple MacBook, OSX provides you some profiles:
