Right, but all such _should_ be delegated to the

So would that be an error condition?

One concept that I had discussed with someone here
(Kev? Alexey?) was some kind of resource that would
deliver a tempfile for another resource. This might
work in simple situations. It also occurs to me that
certain resources might themselves implement
ResourceFactory, e.g. files and urls, which can pretty
easily return a relative file. A buildfile specifying
no basedir would, IMHO, seem to be fairly well
represented by a FileResource that, as a
ResourceFactory, would resolve relative paths against
".". So that might provide some opportunities as
well.
