[Boost-users] boost::units primer needed

Boost Units users, I need to find a *really* good boost::units primer to get me started. we've got some units-based calculations that need to be developed and I hope to make use of boost in order to facilitate those calculations taking place. so far what I am thinking of as a basic type calculation isn't panning out quite right, more likely I am failing to grasp just what I need to do to string together the quantities in accordance with the units framework which allows the calculations to happen properly... I don't know if any of this is making sense. Kind regards, Michael
