Color Transformation Language (CTL).

[Mikhail Lyossin]

About Example script, you may take it from their docs, there are alot of
examples.
For example, to emulate ICC it would be enough to make a 1d lookup table,
but for more comlex transformations, such as RGB to CMYK, 3d and 3d table
lookup would work pretty well and fast. And those lookup tables also can be
generated with CTL.

It'ss a pity it's incompatible with GPL, I didn't notice that =(
