[Boost-users] boost program options - notifier function 0 arguments

Hello

I've been wondering how its possible to call a notifier function with an 
option that doesnt require arguments.

Something like:
po::options_description desc("Allowed options");
desc.add_options()
    ("help", po::value<>()->notifier(&_help_function), "produce help 
message");
Whats the proper way of doing this?
Many thanks in advance
