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