Thanks! That works pretty well. Here's the code I tried:

typedef std::vector< basic_option<char> > vec_opt;
cout << "Parsed command line options (from parsed_options):" << endl;
for(vec_opt::iterator l_itrOpt = l_parsed.options.begin();
     l_itrOpt != l_parsed.options.end();
     ++l_itrOpt)
{
        basic_option<char>& l_option = *l_itrOpt;
        cout << "\t" << l_option.string_key << ": ";
        typedef std::vector< std::basic_string<char> > vec_string;
        for(vec_string::iterator l_itrString = l_option.value.begin();
            l_itrString != l_option.value.end();
            ++l_itrString)
        {
                cout << *l_itrString;
        }
        cout << endl;
}
