+ (description
+ "The Color Transformation Language, or CTL, is a small programming
+language that was designed to serve as a building block for digital color
+management systems. CTL allows users to describe color transforms in a
+concise and unambiguous way by expressing them as programs. In order to apply
+a given transform to an image, the color management system instructs a CTL
+interpreter to load and run the CTL program that describes the transform. The
+original and the transformed image constitute the CTL program's input and
+output.")
