  # This resource allows users to run vbscript on windows machines. We decided
  # not to use scriptcontrol, due to the fact that it works on 32 bit systems only:
  # $script = new-object -comobject MSScriptControl.ScriptControl
  # $script.language = "vbscript"
  # $script.ExecuteStatement($Cmd)
  #
  # For that reason, we call csript.exe directy with the script. Vbscript is
  # embedded in Powershell to ease the file transfer and reuse powershell
  # encodedCommand since train does not allow file upload yet.
  #
  # We run cscript with /nologo option to get the expected output only with the
  # version information.
  #
  # Since Windows does not delete tmp files automatically, we remove the VBScript
  # after we executed it
  # @see https://msdn.microsoft.com/en-us/library/aa364991.aspx
