Attached is a little C++ program to extract global dependency info
from the .deps database.
Compile with the equivalent of:
$ SRCTREE=../devel; BUILDTREE=../devel/build;
$ g++ -I${SRCTREE}/boost -I${SRCTREE}/src -o collect_deps collect_deps.C
-L${BUILDTREE}/src/support/.libs -lsupport -L${BUILDTREE}/boost/libs/regex/src/.libs
-lboostregex
Run like:
$ ./collect_deps `find ${BUILDTREE}/src/ -name "*.o"` | sort -n -r | less
Gives the output below. I think it is fair to say that 88 object files
really _shouldn't_ depend on Bullets.h...
