// class basic_binary_oarchive - write serialized objects to a binary output stream
// note: this archive has no pretensions to portability.  Archive format
// may vary across machine architectures and compilers.  About the only
// guarentee is that an archive created with this code will be readable
// by a program built with the same tools for the same machne.  This class
// does have the virtue of buiding the smalles archive in the minimum amount
// of time.  So under some circumstances it may be he right choice.
