I haven't done any jam for a while, but i'd start with this:
DEPENDS $(<) : $(>) ;
DEPENDS exe : $(<) ;
cproto -o $(<) $(>)
CProto file.cproto.h : file.c ;
Main file : file.c ;
exe is a sudo target used in rule MainFromObjects:
What file includes file.cproto.h? This information might
be needed to get the order of updating right.
