Remove $FreeBSD$: one-line nroff pattern

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

ctags: Support writing to stdout instead of a file.

* Understand "-" to mean stdout as per convention.
* Check that the output is a regular file and ignore -u if not, otherwise we might try to rm /dev/stdout.
* As a bonus, if -u was specified but the output file does not exist, proceed as if -u had not been specified instead of erroring out.

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.

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.

Discussed with: imp, rwatson

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.

Added the EXIT STATUS section where appropriate.

The .Xr files

mdoc(7) police: markup polishing.

Approved by: re

Document conformance to IEEE Std 1003.1-2001.

Sort sections according to mdoc(7).

Create tags for typedefs, structs, unions and enums by default (imply the
-t option). Make a new option, -T, to revert to the old behaviour.

Use `The .Nm utility'

mdoc(7) police overhaul.

Remove unused #includes. lex -> Lex, yacc -> Yacc, ... Some .Nm to .Em
conversions. Sort #includes. Spelling. use errx() instead of err() when
explicit message is given.

Remove whitespace at EOL.

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

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

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Approved by: bde

Add usage string. Typo in man page.

Fix a bunch of spelling errors in a bunch of man pages.
