I personally installed Ramaze on my Ubuntu box. And I must say it's very light weight compared to Rails. I mean you don't even have to generate controllers via the terminal. You can just write it down on your favorite text editor and Ramaze.start then off you go. Well that is you have to use the terminal to start Webrick to run the Controller. But there doesn't seem to be any auto magic behind it. Which is good cuz I myself prefer to structure the app according to my own tastes.
