A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Expand *n't contractions.

Sort sections.

mdoc(7) police: removed HISTORY info from the .Os call.

- VFS_SET(msdos) -> VFS_SET(msdosfs)
- msdos.ko -> msdosfs.ko
- mount_msdos(8) -> mount_msdosfs(8)
- "msdos" -> "msdosfs" compatibility glue in mount(8)

Eliminate mdocNG warnings caused by misplaced or extraneous macro calls.

Prepare for mdoc(7)NG.

mdoc(7) police: use the new features of the Nm macro.

Use Fx macro wherever possible.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Correct use of .Nm. Add missing .El. Add rcsid. Remove unused #include.

Implement Helbig idea of offset calculation reducing mktime() calls
Immediately exit if /etc/wall_cmos_clock not present

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Sort cross references.

English corrections from jdp.
Add main purpose description (MSDOS timestamps)

Correct some man page cross references and file location references.

-i case goes to background pause and acts like -a case on receiving
SIGTERM. This helps to keep CMOS clock updated before reboot.
Idea from J.Wunsch.

Restore back -i, -a

Remove options, run adjkerntz as daemon now
