  if i can jump in, a good way to start playing is to configure and
build for the "sandbox" architecture so you can run it on your x86
system.  for the benefit of a couple friends, i whipped together a
wiki page for that here:

  very simple but enough to get you started, and you can match up
running the commands with the underlying code.
