Has google taken down my favorite ruby api developer's guide

a4chitect

there is a mirror http://groups.google.com/group/SketchUp-Plugins-Dev/web/Ruby-methods.html
(with a little less screen space (due to google groups toolbar and sidebar) but more colors)

and a different approach http://code.google.com/apis/sketchup/docs/developers_guide/index.html (imho less informative, without examples but for quick reference)

=> farewell old guide and thanks for sticking with me for such a long time
a little less 'sketchup' and more google in the address bar
