I have studied the only usage instance of this I could find in testing.jam and since I am just trying to set this on an existing obj target, the example there does not seem relevant.  I believe this is what I would need:

obj timestamp : timestamp.c ;
exe main : main.c timestamp ;
rebuilds main : timestamp ;

If this is correct, I would need to implement something similar to the always rule but with two parameters.  Am I on the right path or is there a better solution for this?

Thanks,
