A single comma was missing to separate the "see also" items in

Allow custom files to be opened and allow sorting by timestamp.

While implementing a tool to import lastlog entries into utmpx, I
noticed lastlogin doesn't allow custom database files to be opened. Add
a -f switch to support this. Also, add -r and -t similar to ls(1),
ruptime(1), etc. where you can sort entries by timestamp and reverse
them. This allows you to spot active/idle users more easily.

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

Alphabetically sort the output of lastlogin(8).

According to the manpage, the entries have to be sorted by uid. This is
no longer possible, since our utmpx implementation is completely unaware
of user IDs. You can safely add entries for multiple users sharing the
same uid.

Make the output less random by sorting everything by name.

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.

Remove stale references to utmp(5) and its corresponding filenames.

I removed utmp and its manpage, but not other manpages referring to it.

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

Mechanically kill hard sentence breaks.
