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.

Cosmetic: Tidy up.
Submitted by: Theo de Raadt <deraadt@cvs.openbsd.org>

Correct the "how to find out if the line is up" example.

Notice that ppp has closed the connection properly.
Remove the timeout hack to notice that ppp has closed the connection.
Remove the ``special case'' hacks for "quit" and "bye", as pppctl
now exits immediately when the connection is closed by ppp.
Suggest a secure "set server" line for connecting ppp & pppctl.
Tidy up and correct a few man page typos.

Style police.
bzero -> memset
index -> strchr
rindex -> strrchr
Use libedit (this should make pppctl a lot more attractive than telnet).

Support interactive mode.

Add a few examples.

Sort cross refereces in section SEE ALSO.

Allow hosts specified by IP number (avoiding
a DNS lookup)
Update doc including the [host:]port syntax.

Allow command line control of ppp through both
TCP and AF_LOCAL sockets.
