When you need to manage one web-server (or AS) there isn't problems. because you make all operations just one time. But what about next situation: you have several servers and need to do the same operations several times? Of course, you can repeat your set of commands several times.

Capistrano uses special DSL for specifying commands.
Yeap, it's perfect solution for executing commands in parallel
