[Boost-users] Multiple "serialize" functions

Newbie question for the boost serialization library.. In my app I want to have two seperate serialization modes: One when I'm saving all the data, and one when I'm creating a 'save game'. The two will be an overlapping set of parameters. Is there a good way to do this with the serialization library? Some way to specify seperate functions to call. I'm about to add a global flag that I can check in my single serialize function, and then check that to determine if I'm saving data or a save game, but this is a bit of a hack and I'd rather have a seperate function. Many thanks John Krajewski
