The eventual goal is to use the profiles to blend colors with CIECAM02.  
This will replace the functionality of the -c parameter. After reading 
Hunt's "Measuring Colour" and Fraser's "Real World Color Management" I 
suspect that what -c currently does is essentially garbage-in garbage-out.

If anyone has some info on profiling digital cameras, I'm interested. I 
get the impression that this is far from a solved problem.
