  94  *      Each kernel has a major and minor version number.  Changes in
  95  *      the major number in general indicate a change in exported features.
  96  *      Changes in minor number usually correspond to internal-only
  97  *      changes that the user need not be aware of (in general).  These
  98  *      values are stored at boot time in the machine_info strucuture and
  99  *      can be obtained by user programs with the host_info kernel call.
 100  *      This mechanism is intended to be the formal way for Mach programs
 101  *      to provide for backward compatibility in future releases.
 102  *
 103  *      [ This needs to be reconciled somehow with the major/minor version
 104  *        number stuffed into the version string - mja, 5/8/87 ]

 106  *      Following is an informal history of the numbers:

 108  *      25-March-87  Avadis Tevanian, Jr.
 109  *              Created version numbering scheme.  Started with major 1,
 110  *              minor 0.
