* Add an "iso-image" action in build.sh, which
invokes make iso-image.
* Document the above in doc/BUILDING.mdoc.
* Re-generate BUILDING.

rather than adding '-s' to make's command line in the makewrapper,
use the .SILENT target based on MAKEVERBOSE's value.
This means that you can do:
./build.sh -N 1 makewrapper
$TOOLDIR/bin/nbmake-$MACHINE
# runs at MAKEVERBOSE==1, with command lines suppressed
$TOOLDIR/bin/nbmake-$MACHINE MAKEVERBOSE=2
# runs at MAKEVERBOSE==2 for this invocation, with command lines shown
* add "releasekernel=conf", to install a gzipped copy of the kernels
built by "kernel=conf" to RELEASEDIR/MACHINE/binary/kernel
build.sh:
* be more consistent in various status messages
* move the {release,}kernel=conf conf parsing code into getkernelconf()
and use in both buildkernel() and releasekernel()
* only warn once when building multiple kernels without updating the tools
Add "makewrapper" operation to build.sh.
[The above changes were suggested by Alan Barrett on current-users@]
Fail if building as non-root unless: UNPRIVED is set, -U is given, or -E
(expert mode) is given.

Improve the examples in BUILDING.
parameters, and a list of "operations" defines what to do.
The full usage is show below. Notes:
`-b' has been deprecated (it always occurs now)
`-d' is replaced by "distribution"
`-R rel' onlys sets RELEASEDIR; use "release" to build a release
`-k kern' has been replaced by "kernel=kern"
`-i idir' has been replaced by "install=idir"
-r now occurs before nbmake is rebuilt
Add a copyright (long due!). Rework the code to (a KNF inspired) ShellNF.
Use functions appropriately. Allow `nb' prefix to be easily changed to
something else. Solve world peace (just kidding)
This is part of the (never achievable) goal of attempting to make
NetBSD easier to build...
--8<-- new usage follows --8<--
Usage: build.sh [-EnorUu] [-a arch] [-B buildid] [-D dest] [-j njob] [-M obj]
[-m mach] [-O obj] [-R release] [-T tools] [-V var=[value]]
[-w wrapper] [operation [...] ]
System build operations (all imply "obj" and "tools"):
build Run "make build"
distribution Run "make distribution" (includes etc/ files)
release Run "make release" (includes kernels & distrib media)
Other operations:
obj Run "make obj" (default unless -o)
tools Build and install tools
kernel=conf Build kernel with config file `conf'
install=idir Run "make installworld" to `idir'
(useful after 'distribution' or 'release')
Options:
-a arch Set MACHINE_ARCH to arch (otherwise deduced from MACHINE)
-B buildId Set BUILDID to buildId
-D dest Set DESTDIR to dest
-E Set "expert" mode; disables some DESTDIR checks
-j njob Run up to njob jobs in parallel; see make(1)
-M obj Set obj root directory to obj (sets MAKEOBJDIRPREFIX)
-m mach Set MACHINE to mach (not required if NetBSD native)
-n Show commands that would be executed, but do not execute them
-O obj Set obj root directory to obj (sets a MAKEOBJDIR pattern)
-o Set MKOBJDIRS=no (do not create objdirs at start of build)
-R release Set RELEASEDIR to release
-r Remove contents of TOOLDIR and DESTDIR before building
-T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in
the environment, nbmake will be (re)built unconditionally.
-U Set UNPRIVED
-u Set UPDATE
-V v=[val] Set variable `v' to `val'
-w wrapper Create nbmake script as wrapper
(default: ${TOOLDIR}/bin/nbmake-${MACHINE})
kernel using the $TOOLDIR toolchain. If kern doesn't contain `/', it will
be searched for in ${KERNCONFDIR} (typically, sys/arch/${MACHINE}/conf).
- Improve ./build.sh usage.
- Add some examples to the documentation.
This is heavily based on [toolchain/18739] from Alan Barrett <apb@cequrux.com>,
with improvements by me.
