+ <h3>Summary</h3>
+ This tool has several different but related functions. When given as
+ a file argument an ICC profile containing vcgt "gamma" curves, or an
+ Argyll video calibration .cal file, it will load that calibration
+ into the chosen display. It can also install or uninstall a profile
+ in the system for the chosen display, or set the display calibration
+ to that in the currently installed system profile. By default it
+ displays a test window the same as that used by dispcal and
+ dispread, to test this functionality. It can also be used to test
+ the ability to load video card LUT curves to each display, and to
+ test how the console Bell will sound when used with some instruments
+ (ie. Eye-One Pro).<br>
+ <br>
+ [Note that in OS X 10.7 Lion, changes to the default system profile
+ permissions mean that you can't set a calibration persistently when
+ the default system profile is being used, unless you run as root
+ (ie. use sudo). Note that you do <span style="font-weight: bold;">not</span>
