This project is aimed at making multi machine simple.
This is based on PowerShell, Hyper-V and takes advantage of new feature Desired State Configuration (DSC).
Define the configuration of how many VMs should be created using a JSON file. The format is subset of http://msdn.microsoft.com/en-us/library/dn249758.aspx. Specify the OS image, what data folders/PS modules to be coped to the data disk, boom you go!
