And that's why I've been saying that Make isn't really a very good tool for 
maintaining that sort of thing.

You already have that tool. It just doesn't output its results in a form 
that Make can consume. Certainly the tools that generate the documentation 
files know which output files depends on which other files.

Sure. I was asking whether if you change a test case, does "make test" just 
run that one test case?  I've never seen that done.
