In Rails developement, we will be using running "rake" to run your tests or maybe you've used "rake db:migrate" to run your migrations. Many of us know about Make scripts. What if you want to run ruby scrupts inside make then we need rake for that. Did you realize that you can write your own tasks or create your own library of useful Rake files?
Greg of rails envy gave nice article on Rails Rake ..:-)
