[Boost-users] [program options] some docs suggestion

It would be really helpful to know that varaibles map is a derivative of std::map<...>. I was wondering where the variables_map::count(...) come from in getting started example... if (vm.count("help")) { cout << desc << "\n"; return 1; } Only after looking into the source of variables_map helped :( With Kind Regards, Ovanes Markarian
