UPDATE: From PowerCLI 5.1 these functions are no longer required as they have been included in the *-AdvancedSetting cmdlets.
The following functions are used to retrieve infromation from a VM or multiple VM's advanced configuration or VMX file and also used to Set a configuration for a single or multiple VMs.
Note: The first function was taken from the "VMware vSphere PowerCLI Reference" book which can be found here: http://PowerCLIBook.com
function Set-VMAdvancedConfiguration {

.SYNOPSIS
