GlobalLB server manipulation in PowerShell

I am trying to set up an automated method of creating GlobalLB objects such as Servers, Virtual Servers, Pools and Wide-IPs using PowerShell. I managed to installed the snapin and initialize the connection. Then I managed to create an object with the name of the server. But I can't seem to get the serveripdefinitions working. Are there any code samples that will help create these objects?.
