How to print a stack trace in NodeJS?

Does anyone know how to print a stack trace in nodejs?

From stackoverflow

• http://github.com/emwendelin/javascript-stacktrace This looks promising.

• Any Error object has a stack member that traps the point at which it was constructed.

  var stack = new Error().stack
  require("sys").puts( stack )
  

  sirhc : or just `sys.puts(new Error().stack)` (after adding the system module)
