[Openicc] [argyllcms] OT: PDF frustration

[Leonard Rosenthol]

I think you'd do better with your $$ to hire/contract the original  
author of Xpdf (on which Poppler is based) to get him to add CM  
support...He is familiar with both the code base and PDF itself -  
though he may need a bit of background on CM - but not much...
