   "Stride are considered individual test numbers.  Start, End,or stride "
   "can be empty.  Optionally a file can be given that contains the same "

   "a non-interactive mode. On Windows this means that in non-interactive "
   "mode, all system debug pop up windows are blocked. In dashboard mode "
   "(Experimental, Nightly, Continuous), the default is non-interactive.  "
   "When just running tests not for a dashboard the default is to allow "

   "debugging."},
  {"--build-and-test", "Configure, build and run a test.",
   "This option tells ctest to configure (i.e. run cmake on), build, and or "
   "execute a test. The configure and test steps are optional. The arguments "
   "to this command line are the source and binary directories. By default "
   "this will run CMake on the Source/Bin directories specified unless "
   "--build-nocmake is specified. Both --build-makeprogram and "
   "--build-generator MUST be provided to use --built-and-test. If "
