most samples still have a .cnc file. My guess is the "spec translator" to generate header files from this was discontinued. Is the recommended approach now to describe the CnC graph in the header file, rather than in .cnc, oneself?
Sidenote: The 0.7.003 release notes state that the "spec translator" was removed. I'm assuming this is the tool formerly used to compile header files from .cnc graph descriptions (relating to the #GEN_HEADER=$(CNCFILE:.cnc=.h) line still present in the Makefiles).
