Deorbit catman. The tradeoff of disk for performance has long since tipped
in favor of just rendering the manpage instead of relying on pre-formatted
catpages. Note, this does not impede the ability to use existing catpages,
it just removes the utility to generate them.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

In su(1), fix option ordering and clarify that the login class specified
must be defined in login.conf.

Attempt to clear up some confusion in the following example, by stating
the '-c' argument is passed to the shell, not to su(1), which would
indicate the login class.

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.

- add the -m option to the example commands because they would fail w/o it
as the ``man'' user does not have a valid shell by default.
