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