Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Move cron.d/at to usr.bin/at/

This helps with pkgbase as it tags this as a config file so it is handled as
such

Build at(1) with NO_WFORMAT instead of WARNS=1.

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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

WARNS=2 fixup.

Set BINOWN=root explicitly for setuid root binaries.

This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

MAN[1-9] -> MAN.

Don't use MANDEPEND and MANSRC.

$Id$ -> $FreeBSD$

Eliminate compiler warnings from -Wall

Remove useless `BINOWN=root' now that it is the default.

$@ is deprecated, use ${.TARGET} instead. Ditto for other single character
$n.

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.

Use ${ECHO} instead of `echo' so that `make -s' is fairly quiet.

making <page>.1 from <page>.man

Upgrade.
