Why did you write dcpTool?
In a fit of frustration at not being able to do what I wanted to do (profile to the numbers) with Adobe’s DNG profile Editor
 
Why is dcpTool a command line utility?
DCP files contain a large amount of detailed data - there simply isn’t a good way to present that much data graphically in a way that will make sense, except by doing the same very high level thing as Adobe’s DNG profile editor.
 
Will the DCP files I get be compatible with Adobe Lightroom or Camera Raw?
The DCP file generation is done by Adobe’s own DNG SDK code, which is what goes into Adobe’s own products.
 
Ok, I got to a modified DCP file, how do I install it?
Exit from any running Adobe applications, then copy the file to following location:
  1. On Mac OS X:
  2. /Library/Application Support/Adobe/CameraRaw/CameraProfiles (Pre-Lightroom 4.3), or
  3. /Users/Username/Library/Application Support/Adobe/CameraRaw/CameraProfiles/ (Lightroom 4.3 and later)
  4. On Windows 2000 / XP:
  5. C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles
  6. On Windows Vista, Windows 7 and Windows 8:
  7. C:\ProgramData\Adobe\CameraRaw\CameraProfiles (Pre-Lightroom 4.3), or
  8. C:\Users\Your_username\AppData \Roaming\Adobe\CameraRaw\CameraProfiles (Lightroom 4.3 and later)
 
Why XML?
XML is human readable, and editable in a text editor, but still well enough structured to allow it to easily be processed by automated tools.
 
Why libxml2?
Ummm......seemed like a good idea at the time.
