Re: [Boost-users] Serialization and BGL

The serialization library is designed to make the possible - and hopefully
easy - without modification of the BGL library.  This depends on the BGL
library exposing enough information in order to save and load back the state
of the objects it uses.  I can't know that it does this.  Note that
serialization is implemented totally non-intrusively for all std
collections, variant and now shared_ptr.  So what you want to do should be
possible.
