/**
 * Used to validate that content does not contain virtualized payloads. The current
 * cmdline options are:
 * -CheckEngine
 *     Checks all packages currently mounted in the engine
 * -CheckProject
 *     Checks all packages currently mounted in the current project
 * -CheckDir=XYZ (XYZ is the path to the directory, use '+' as the delimiter if supplying
 * more than one path)
 *     Checks packages in the given directory and all subdirectories
 * any or all of which can be passed to the commandlet.
 *
 * If virtualized payloads are found then the package path (or file path if CheckDir
 * indicates a directory that is not currently mounted by the project) is logged
 * as an error and the commandlet will eventually return 1 as a failure value.
 *
 * Because the commandlet is the VirtualizationEditor module it needs to be invoked
 * with the command line:
 * -run="VirtualizationEditor.CheckForVirtualizedContent"
 *
 * Followed by
