As already mentioned, libfetch can do the parsing - but fetchParseURL
is either buggy or needs extending; I haven't checked. A simple C
program to use that and spit out the parts is easy (see attached).

I have a good idea for how to do output formatting; I think I'm going
to work on that tonight. The real question is whether or not DES will
let us fool with libfetch to add this stuff.
