* Another change to low-level derivations. The last one this year, I
promise :-) This allows derivations to specify on *what* output paths of input derivations they are dependent. This helps to prevent unnecessary downloads. For instance, a build might be dependent on the `devel' and `lib' outputs of some library component, but not the `docs' output.
