Remove $FreeBSD$: two-line nroff pattern

Remove /^\.\\"\n\.\\"\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.

Sort sections.

Scheduled mdoc(7) sweep.

General overhaul:
- Makefile: WARNS=6
- man page: sort options, better xrefs, informative BUGS section
- C source: proper option parsing, use printer control (.ctl) device,
removed heaps of bit rot, style(9) cleanup, WARNS=6 cleanup.

Priner control devices are now lpt*.ctl.

Mechanically kill hard sentence breaks.

The .Nm utility

Remove whitespace at EOL.

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

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

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

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

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Remove incorrect section name. Use .Pa or .Ar instead of .Em.

$Id$ -> $FreeBSD$

Add missing -s option.

PR: docs/10378

Add -e option and change unit to device access in lptcontrol.8

Change unit to device access in lptcontrol.c. Now usage is

lptcontrol -i | -p | -e [-d /dev/lpt?]

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq.

Use err(3).

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.

Correct some man page xrefs, and some other minor changes to bring some
man pages up to mdoc guidelines and fix some minor formatting glitches.
Also fixed a number of man pages to not abuse the .Xr macro to
display functions and path names and a lot of other junk.

Make it possible to run lptcontrol on a printer port which does not
actually have a printer connected or online:
- MAKEDEV: remove all signs of lpa
add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile add lptcontrol
- sys/i386/isa/lpt.c implement the LP_BYPASS flag: when a unit is
opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used
to pass ioctls. (giving us /dev/lpctl?)
- lptcontrol.c use /dev/lpctl? (LP_BYPASS)
-f flag removed, -u flag added
- lptcontrol.8 document changes in lptcontrol
rewrite using mandoc macros
