/**
 * Creates a csv file containing info about all of the payloads in a set of packages.
 * By default the commandlet will parse the payloads of all packages in the current
 * project but this can be overridden with the cmdline switch -PackageDir=XYZ which
 * will allow the commandlet to parse the payloads of the packages in a given directory.
 * 
 * Because the commandlet is the VirtualizationEditor module it needs to be invoked 
 * with the command line:
 * -run="VirtualizationEditor.GeneratePayloadManifest"
