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); }

Is there a way to do something like: desc.add_options() ("input", po::valuestd::string(&InputFile)->required(), "Set input file.")

That will perform that check for me?

Not at the moment. Feel free to file a request at svn.boost.org - Volodya
