Here's a dump of the test I was attempting to add with the following options:

  cl::OptionCategory Cat1("Category One", "  Category One description");
  cl::OptionCategory Cat2("Category Two", "  Category Two description");
  cl::opt<bool> GeneralOpt("general-option");
  cl::opt<bool> Cat1Opt("category1-option", cl::cat(Cat1));
  cl::opt<bool> Cat2Opt("category2-option", cl::cat(Cat2));
  cl::opt<bool> Cat1AndCat2Opt("category1-and-category2-option", cl::cat(Cat1), cl::cat(Cat2));



  USAGE: prog [options]
  
  OPTIONS:
  
  Category One:
    Category One description
  
    --category1-and-category2-option    -
    --category1-option                  -
  
  Category Two:
    Category Two description
  
    --category1-and-category2-option    -
    --category2-option                  -

    --program-test-string-arg1=<string> -
    --program-test-string-arg2=<string> -
