As I said, I think Java has a better and more flexible way of doing it.  One
limitation of using the reversed domain name, though, is that not everyone has
one.

I namespaces (or packages, or whatever) should be considered for POV-Ray 4.0,
but I don't how best to implement.  There are other ways to do it beyond what
we've discussed here.
