I know, and that's what I am doing anyway. I just thought - after
reading about File::SEPARATOR - that this would be a good way 
to pass path parameters on to external processes.

So this is not OS dependend, and within *every* Ruby implementation
it is supposed to be a slash ... not that much sense defining
it as a named constant then, isn't it?
