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.

The NetBSD Foundation has granted permission to remove clause 3 and 4
from their software.

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

The referenced section name is 'Formats', not 'FORMATS'.

Add some more examples. It always takes me a long time to find the S
modifier (-t is ignored without it).

Bring in NetBSD's version 1.11, which includes documenation for the new
inode birthtime display, and quite a bit of mdoc cleanup, which brings
it much more in line with our mdoc style.

A much better description of the -q option.

Obtained from: Andrew Brown <atatat@NetBSD.org>

A cooperative effort...

1. Update the code to the latest from NetBSD, which includes:
* A new command line option to suppress stat(2) errors
* Output is now done via stdio
* Fixes for bitwise OR'ing of letters

2. Andrew from NetBSD merged in our own Johan's readlink patches.

3. Andrew also merged in some brucifications.

I made some small contributions to the header cleanup, and tried
to generally improve the overall style(9)'ishness. I also documented
the new -q option and added the *LINKS to the Makefile.

All responsibility for mistakes in merging the contributions
from the above is mine.
