**
** The structure of the archive file generated is influenced heavily by the
** description of the MFC archive format published somewhere in the MSDN
** library.
**
** Two major shortcomings of the format I use are that there is no version
** control and no support for storing the non-default portions of objects.
** The latter would allow for easier extension of objects in future
** releases even without a versioning system.
