Introducing psake - James Kovacs:

"psake is a build automation tool written in PowerShell. It avoids the angle-bracket tax associated with executable XML by leveraging the PowerShell syntax in your build scripts. psake has a syntax inspired by rake (aka make in Ruby) and bake (aka make in Boo), but is easier to script because it leverages your existent command-line knowledge."
