 If I have a list of 10 parameters, and all are required,

 I end up with a giant block of these:

         std::cout << "Input was not set." << std::endl;

 It would be nice to do something like:
             ("input", po::value<std::string>(&InputFile)->required(), "Set
 input file.")

 That will perform that check automatically.
