ok, i haven't poked around there yet, i'll look at that later.

good point ... i originally envisioned someone perhaps wanting to do
nothing more than just downloading and running the pre-built images to
see what all the fuss was about. if that's really not considered a
useful example, i'll forget about it.

ah, that i can provide. in the runqemu usage message, you see the
suggestion:
$MYNAME qemux86-64 core-image-sato ext3"
but that assumes you're in a build directory. of course, using the
adt-installer as you suggested might make all this moot.
