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.

The including makefile's directory is tried first for .include "...".

$Id$ -> $FreeBSD$

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.

Fix secrdist sharedlib bug.

Make the "distribute" target build the "des" distribution. Make des'ed
init and ed, by pointing to real sources.

1) don't make bdes yet
2) fix .include in secure/lib/Makefile.inc
3) fix afterinstall rule in libcrypt/Makefile
Submitted by: Geoff Rehmet

add Makefiles for secure/lib. Makefile.inc just includes src/lib/Makefile.inc
in order to get things like SHLIB_MAJOR etc.
