Trying to get started with ROO and Surf by following
http://www.springsurf.org/sites/1.0....tml/intro.html

i get this error when running
roo> addon install --url http://www.springsurf.org/downloads/...-roo-addon.zip

ERROR:
Command 'addon install' not found (for assistance press CTRL+SPACE or type "hint" then hit ENTER)
addon search --requiresCommand "addon install" found no matches

Same problem and I get no answers from anyone from the Spring, Surf or Roo project. However, I did get surf addon in roo working.
