But they are... Just click on the link above and you have an example :)
And if load a web page is really too much, here is what you will find:

Example:

/////
namespace po = boost::program_options;

void handler(const std::vector<std::string> &parameters)
{
   for (std::vector<std::string>::const_iterator it = parameters.begin();
        it != parameters.end();
        ++it)
     std::cout << *it << std::endl;
}

void exit_(unsigned int code = 0)
{
   exit(code);
}

int main(int argc, char **argv)
{
   boost::cli::commands_description desc;
   desc.add_options()
     ("handler", po::value< std::vector<std::string> 
 >()->notifier(&handler)->multitoken())
     ("exit", po::value< unsigned int >()->notifier(&exit_))
     ;

   boost::cli::command_line_interpreter cli(desc, ">");
   cli.interpret(std::cin);
}
//////

Output:

 >handler
error: required parameter is missing in 'handler'
 >handler 1 2 3
1
2
3
 >toto
error: unknown option toto
 >exit 0
Press any key to continue . . .
