Remove superfluous paragraph macro.

mdoc: make pages render with mandoc

It's a bit more pedantic regarding .Bl list elements. This has an added
benefit of unbreaking the ipfw(8) manpage, where groff was silently
skipping one list element.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

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.

Merge IPv6-capable mtest(8) from MLDv2 branch.

Update mtest(8) manual page.

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

Merge a slightly cleaner and SSM capable mtest(8).

Mechanically kill hard sentence breaks.

The .Nm utility

Prepare for mdoc(7)NG.

$Id$ -> $FreeBSD$

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.

Use err(3). -Wall cleaning.

Add the one line description of the man page at the top so
that "whatis" will report something more than just "mtest".

Make mtest build. Write a makefile and a man page.
