[Boost-users] [serialization] Creating new archives derived from polymorphic archive

Hi, How do I get started? I want to create a set of custom archives that include such features as a small header, CRC, digital signatures, etc. I want to put this into a DLL, so I want to go the polymorphic route. There are directions for creating new archives from the template versions, but not for the polymorphic versions. I'm not sure the starting point is the same, so I thought I'd ask first, as this is stretching my abilities a bit. Thanks, -Bob
