An example for those who don't like the web pages.

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
