2982	Required Arguments	David Doria <daviddoria@…>	Sascha Ochsenknecht	"If I have a list of 10 parameters, and all are required,

I end up with a giant block of these:

if(!vm.count(""input""))
    {
        std::cout << ""Input was not set."" << std::endl;
        exit(-1);
    }

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

That will perform that check automatically."	Feature Requests	closed	Boost 1.42.0	program_options	Boost Development Trunk	Not Applicable	fixed	Required Arguments	s.ochsenknecht@…
