// 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. | |
