Hello list!
I took the time to create a small Eclipse package with the RDT and RoR development tools, together with subversion integration, using yoxo's Eclipse on demand download service.
You can get it here (or search for Ruby, if it doesn't show up)

That's my contribution, as little as I can contribute to the Ruby community right now, until I'm good enough with Ruby to understand most of the topics on this list
