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/

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.

Not only had I included a syntax / style error, nice.3 is also
deprecated.

Revert the commit that I made, there is a lot of discussion
and it's not accurate anyway

Add wording about the priority range and
mention what effect this has at certain
values.

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

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.

Sort sections.

Added the EXIT STATUS section where appropriate.

english(4) police.

Document the fairly obvious effect of the PATH environment variable.

Make the Examples section consistent with the rest of the system manual
pages: description of command first, then command as typed (no shell prompt)
using Dl macro.

Correct History: nice(1) appeared in V4.

Support the SUSv3 -n option and the "--" end of options marker.
Replace "command" with "utility" in the manual page & source to be more
consistent with the terminology used in the standard, and to hint that
shell builtin commands won't work.

According to POSIX, exit status must be 127 if the requested utility was not
found, 126 if the execvp() failed for any other reason.

Similar to rev. 1.6 to src/usr.bin/env/env.c

Use `The .Nm utility'

Remove whitespace at EOL.

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

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

Fix a typo and a punctuation mistake, the two of which conspired
against the reader.

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

Correct some hard sentence breaks. Only those surrounding the previous
commit and those which cause ugly nroff output have been fixed, since
the purpose of the style guideline which they contravene is to reduce
the sizes of deltas.

Improve shell documentation:

* Consistently misspell built-in as builtin.

* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).

* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.

* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.

* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.

* Undo English contractions.

Revert $FreeBSD$ to $Id$

Sort cross references.

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.

Match the reality. The man page was completely wrong.
