$(basename $0)    Tool for configuring a VMWre VM for use with DEP workflows.

Required arguments:
  --vm            The path to the VM (.vmwarevm) you want to modify.
                    Eg. --vm '~/Desktop/TestVM.vmwarevm'
Optional arguments:
  --serial        The serial number you'd like to hard code into the VM. 
                    Eg. --serial 'ABCDEF123456'
