okay i've finally gotten to this. go here:

  http://www.transami.net/ruby/

and you can download the tgz. simply install it by making a directory
called gutopia within ruby's site_path and copying the contents of the
.tgz to it.

in the directory samples you'll find what your looking for. by the way
the samples are very much "under construction", and i think one of them
has a require 'yaml' in there. so if your don't have that you'll either
need to get rid of the require or install yaml (which isn't a bad thing
;-)

yes, your right. none of the stuff on the web page has yet been
implemented, all of that came after i wrote the preliminary code.

i see what you're saying. more of a class architecture. okay, i'll work
on it soon as i can.
