   "This option tells ctest to perform act as a Dart client and perform "
   "a dashboard test. All tests are ModeTest, where Mode can be Experimental, "

   "This option tells ctest to load in a configuration script which sets "
   "a number of parameters such as the binary and source directories. Then "
   "ctest will do what is required to create and run a dashboard. This "
