instead of sprinkling them out over many disjoint files. This is a follow-up
to achieve the same goal in an incomplete rev.348521.

upper the warning level to 3

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.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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

Add endianness support to cap_mkdb(1), useful for cross builds.

Clean up after utilizing FILES.

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

Install files via FILES.

WARNS=2 fix, kill register keyword, use __FBSDID().

NO_WERROR set because of hard-to-fix warnings originating in
system headers.

beforeinstall -> SCRIPTS.

MAN[1-9] -> MAN.

Basically reverse last commit which was plain wrong.

delete unused variable BINDIR=/usr/libexec
/usr/bin -> ${BINDIR}

Use ${COPY} instead of -c for installing non-source files.

Change `install' to `${INSTALL}' so that default install flags can be
specified in the top level Makefiles.

Build database at build time instead of at install time.

More merry makefile munging for man page compatability.
