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.

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

mdoc(7) police: Use the new .In macro for #include statements.

Remove whitespace at EOL.

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

mdoc(7) police: normalize .Nd.

Introduce .Lb macro to libutil manpages
Sort .Nm values in some manpages
Remove explicit note about compiling with -lutil, it's implicitly
declared by .Lb macro now.

Add the "use -lutil" line to all functions that require it so people like
Dan Papsian <bugg@bugg.strangled.net> don't anger wpaul and myself with
silly linking errors.

$Id$ -> $FreeBSD$

add MLINKS for two functions used from login_auth.c
comment out unused functions from login_auth.3

Fixed function types in synopsis.

Commented out docmentation of nonexistent authenticate() and
auth_timesok(). authenticate() seems to be obsolete and
auth_timesok() never existed in FreeBSD.

Revert $FreeBSD$ to $Id$

Sort cross references.

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.

Library functions relating to the login class capabilities database,
including manpages.
