Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Remove $FreeBSD$: one-line nroff pattern

Remove /^\.\\"\s*\$FreeBSD\$$\n/

Remove a commented out line before kvm_getprocs(3)

The commented out return value for kvm_getprocs(3) was misleading -- the
uncommented line is correct.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Now kvm_getenvv() and kvm_getargv() don't need procfs(5).

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.

Remove the advertising clause. UCB did this some time ago, but these
files were never updated to reflect that.

MFC After: 2 days

Sort sections.

Document the fact that kvm_getenvv(3) requires procfs to be mounted
on /proc in order to operate correctly.

Mechanically kill hard sentence breaks.

Markup, grammar, punctuation.

Update man page to reflect additional flag to allow selection of threads.

Document KERN_PROC_PROC, update KERN_PROC_ALL description.

Add sys/user.h to the list of includes. Without it you lack a definition of
'struct kinfo_proc' for calls to kvm_getargv() and kvm_getenvv().

$Id$ -> $FreeBSD$

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.

41 headers must be implicitly included and one more (<sys/param.h>) must
be explicitly included before kvm_getprocs() can be used.

Update the man page for kvm_getprocs.3 to reflect our sysctl-based
kvm mechanism.
