How to make Compass to watch several folders simultaneously?

I'm using Compass + Sass in order to manage/combine my `.css` files. So I have the following folder structure: ``` Root --Module ----css ----sass --Module ----css ----sass --Module ----css ----sass ``` And here what I'd like to achieve: during development phase I'd like to point compass to my root folder and it should watch for any changes in files located at `sass` directories (in each `Module`). Once one of the .sass files changes - appropriate `.css` file should be generated (for the module changed `.sass` belongs to) and put into `css` folder under the same `Module`. Is it possible? My guess I should use `config.rb` for this purpose, but I'm not sure how to do this properly. Could someone point me to the solution or just describe general idea of how to do it? EDIT: I'm on Windows environment, so can't use Linux commands (I can install Cygwin, but I'd prefer to avoid it) Thanks
