[Haskell-cafe] Searching for dependent code

I don't know what the state of the art is, but for chasing down a tree of
dependencies to determine what needs to be rebuilt, there's always make.
Usually a human hand-codes the dependencies of each file in the Makefile --
but if you could automate that, make could do the rest.

Note also that shake is a make alternative written in Haskell, with (gross
understatement here) better syntax.
