Well, back when I was still doing profile editing I too had these
scripts which I could use to determine what the "look" of a camera or
process was, and then derive a profile to achieve this desired look
from some other camera. Within limits. After writing these scripts,
for my own entertainment,  I batch-applied my scripts to over a
hundred profiles from a popular commercial Raw converter. I never
quite figured out what the legal implications of such algorithmic
reverse engineering and reprocessing are :)
