/// Socket option for determining whether an IPv6 socket supports IPv6

/**
 * Implements the IPPROTO_IPV6/IP_V6ONLY socket option.
 *
 * @par Examples
 * Setting the option:
 * @code
 * asio::ip::tcp::socket socket(my_context);
 * ...
 * asio::ip::v6_only option(true);
 * socket.set_option(option);
 * @endcode
 *
 * @par
 * Getting the current option value:
 * @code
 * asio::ip::tcp::socket socket(my_context);
 * ...
 * asio::ip::v6_only option;
 * socket.get_option(option);
 * bool v6_only = option.value();
 * @endcode
 *
 * @par Concepts:
 * GettableSocketOption, SettableSocketOption.
