xcalib is a program that allows you to use ICC profiles (to load its 'vcgt'-tag) for display calibration on X11-Servers with XVidModeExtension supported (like X.org or XFree86 4.x.x). It can't create the profiles so you need to acquire them elsewhere (e.g. from some commercial program or from your display vendor).
State Changed From-To: open->closed New port added, thank you!
