        {"no-message", "Suppress error"},
        {'a', "Build all targets"},
        {'x', "xxx", ""/*no desciption*/},
        {"in", &in, "input file"},
    });

    auto map = po::parse_command_line(ac, av, desc);

    if (!map.count("in")) {
        std::cerr << "blah blah\n\n" << desc;
        return 1;
    }

    std::cout << "in: " << in << "\n";
