Script spawner not found on rails

I was following this tutorial fro开发者_StackOverflow社区m capistrano: http://www.capify.org/index.php/From_The_Beginning#Spinners_and_Spawners

But at a certain point, I couldn't go on because I don't have a script/spawner file. So, what can I do instead?

Thanks in advance

Just found it, it turned into a rails plugin since 2.3
