Yes.  I'm a strong believer in letting the computer figure out
bookkeeping details.

True.  Actually, I just reread the "Recursive Make Considered Harmful"
article and there are a lot of suggestions there that I think would be
benificial.  The article premotes dependency files in each subdirectory
that are automatically rebuilt.  It would be a good goal to strive to
make this easy in Rake.
