How would this relate to namespaces? For instance, lattice imports grid (and a few things from stats and graphics). If I keep grid in the depends field, loading lattice does a require(grid), which defeats one of the purposes of having namespaces. If I leave it out, nothing bad seems to happen as long as grid is installed, but there should be some indication in the DESCRIPTION that that grid is a requirement. None of the other fields seem appropriate.
