Remove $FreeBSD$: one-line nroff pattern

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

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.

mdoc(7) police: Removed redundant .Ns calls.

The .Nm utility

Remove whitespace at EOL.

mdoc(7) police: split punctuation characters + misc fixes.

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.

Import of the keyserv daemon needed for Secure RPC.

This version supports both the keyserv v1 and v2 protocols. It uses the
new AF_LOCAL transport so that only local processes can use it for
storing/retrieving keys, and it uses the SCM_CREDS kernel hack for
authentication. With these two modifications, we don't need the keyenvoy
program normally used with RPC 4.0.

Note that if libdes.so.3.x is present on the system when keyserv
is started, Secure RPC will run with normal DES encryption. If not,
everything falls back to RC4 with a 40 bit key.
