  40  *      Each kernel has a major and minor version number.  Changes in
  41  *      the major number in general indicate a change in exported features.
  42  *      Changes in minor number usually correspond to internal-only
  43  *      changes that the user need not be aware of (in general).  These
  44  *      values are stored at boot time in the machine_info strucuture and
  45  *      can be obtained by user programs with the host_info kernel call.
  46  *      This mechanism is intended to be the formal way for Mach programs
  47  *      to provide for backward compatibility in future releases.
  48  *
  49  *      Following is an informal history of the numbers:

  70  *
  71  *      25-March-87  Avadis Tevanian, Jr.
  72  *              Created version numbering scheme.  Started with major 1,
