[boost] boost::program_options question - enabling multiple usage of the same switch

Hi, This question was originally brought up here: http://lists.boost.org/boost-users/2006/08/21633.php but unfortunately was not answered. What I basically want to do is to enable something like running $ myprog -v -v -v Where -v is some Boolean switch.
