- /*
- * Each kernel has a major and minor version number. Changes in
- * the major number in general indicate a change in exported features.
- * Changes in minor number usually correspond to internal-only
- * changes that the user need not be aware of (in general). These
- * values are stored at boot time in the machine_info strucuture and
- * can be obtained by user programs with the host_info kernel call.
- * This mechanism is intended to be the formal way for Mach programs
- * to provide for backward compatibility in future releases.
- *
- * Following is an informal history of the numbers:
- *
- * 28-Sep-94 David E. Bohman
- * NEXTSTEP Release 4.0.
- *
- * 03-Sep-91 Doug Mitchell
- * Major 3 for NeXT release 3.0.
- *
- * 04-Mar-90 Avadis Tevanian, Jr.
- * Major 2, minor 0 for NeXT release 2.0.
- *
- * 11-May-89 Avadis Tevanian, Jr.
- * Advance version to major 1, minor 0 to conform to NeXT
- * release 1.0.
- *
- * 05-December-88 Avadis Tevanian, Jr.
- * Aborted previous numbering, set major to 0, minor to 9
- * to conform to NeXT's 0.9 release.
- *
- * 25-March-87 Avadis Tevanian, Jr.
- * Created version numbering scheme. Started with major 1,
- * minor 0.
