 .Sh DESCRIPTION
 The
 .Nm
 file overrides various parameters used during the build of the system.
+.
 .Sh NETBSD SYSTEM VARIABLES
+.
 Listed below are the
 .Nm
 variables that may be set that affect the
 .Nx NetBSD
 system build,
 the values to which each may be set,
 a brief description of what each variable does,
 references to relevant manual pages,
 notes (including any interaction with
 .Sy build.sh ) ,
 and the default value of each variable.
+.
 .de DFLT

 if
 .Sy \\$*
 is defined,
 usually in the Makefile before any
 .Xr make 1
 .Cm \&.include
 directives.

 .Pp
 Forced to

 if
 .Sy \\$* .

 .de YorN
 Can be set to

+.
 .Bl -tag -width 14n
+.
 .\" These entries are sorted alphabetically.
+.
 .It Sy BSDOBJDIR
 The real path to the object directory tree for the
 .Nx
 source tree.
 .DFLT
 .Dq Pa /usr/obj .
+.
 .It Sy BSDSRCDIR
 The real path to the
 .Nx
 source tree, if
 .Sy NETBSDSRCDIR
 isn't defined.
 .DFLT
 .Dq Pa /usr/src .
+.
 .It Sy BUILD
 If defined,
 .Sq "make install"
 checks that the
 .Xr make 1
 targets in the source directories are up-to-date and
 re-makes them if they are out of date, instead of blindly trying to install
 out of date or non-existent
 .Xr make 1
 targets.
 .DFLTu
+.
 .It Sy BUILDID
 Identifier for the build.
 If set, this should be a short string that is suitable for use as
 part of a file or directory name.
 The identifier will be appended to
 object directory names, and can be consulted in the
 .Xr make 1
 configuration file in order to set additional build parameters,
 such as compiler flags.
 It will also be used as part of the kernel version string,
 which can be shown by
 .Dq Li uname \-v .
 .DFLTu
+.
 .It Sy BUILDINFO
 Optional multi-line string containing information about the build.
 This will appear in
 .Sy DESTDIR Ns Pa /etc/release ,
 and it will be stored in the
 .Va buildinfo
 variable in any kernels that are built.
 When such kernels are booted, the
 .Xr sysctl 7
 .Va kern.buildinfo
 variable will report this value.
 The string may contain backslash escape sequences, such as
 .Dq "\e\e"
 (representing a backslash character)
 and
 .Dq "\en"
 (representing a newline).
 .DFLTu
+.
 .It Sy BUILDSEED
 .Xr g++ 1
 uses random numbers when compiling C++ code.
 This variable seeds the
 .Xr g++ 1
 random number generator using
 .Fl frandom-seed
 with this value.
 By default, it is set to
 .Do NetBSD-( Ns Em majorversion ) Dc .
 Using a fixed value causes C++ binaries to be the same when
 built from the same sources, resulting in identical (reproducible) builds.
 Additional information is available in the
 .Xr g++ 1
 documentation of
 .Fl frandom-seed .
 .DFLTu
+.
 .It Sy CDEXTRA
 A space-separated list of files or directories that will be
 added to the CD-ROM image that may be create by the
 .Sy build.sh
 .Dq iso-image
 or
 .Dq iso-image-source
 operations.
 Files will be added to the root of the CD-ROM image,
 whereas directories will be copied recursively.
 If relative paths are specified, they will be converted to
 absolute paths before being used.
 .Em Note :
 If using
 .Sy build.sh ,
 multiple paths may be specified via multiple
 .Fl C
 options, or via a single option whose argument contains multiple
 space-separated paths.
 .DFLTu
+.
 .It Sy CONFIGOPTS
 Additional flags to
 .Xr config 1
 when building kernels.
 .DFLTu
+.
 .It Sy COPTS
 Extra options for the C compiler.
 Should be appended to (e.g.,
 .Sy COPTS+=-g ) ,
 rather than explicitly set.
 .Pp
 .Em Note :
 .Sy CPUFLAGS ,
 not
 .Sy COPTS ,
 should be used for
 compiler flags that select CPU-related options.
 .Pp
 .Em Note :
 .Sy CFLAGS
 should never be set in
 .Nm .
+.
 .It Sy CPUFLAGS
 Additional options passed to the compiler/assembler to select
 CPU instruction set options, CPU tuning options, etc.
 .Pp
 .Em Note :
 Such options should not be specified in
 .Sy COPTS ,
 because some parts of the build process need to override
 CPU-related compiler options.
 .DFLTu
+.
 .It Sy DESTDIR
 Directory to contain the built
 .Nx
 system.
 If set, special options are passed to the compilation tools to
 prevent their default use of the host system's
 .Sy /usr/include , /usr/lib ,
 and so forth.
 This pathname must be an absolute path, and should
 .Em not
 end with a slash
 .Pq /
 character.
 (For installation into the system's root directory, set
 .Sy DESTDIR
 to an empty string, not to
 .Dq / ) .
 The directory must reside on a file system which supports long file
 names and hard links.
 .Pp
 .Em Note :
 .Sy build.sh
 will provide a default of
 .Dq Pa destdir . Ns Sy MACHINE
 (in the top-level
 .Sy .OBJDIR )
 unless run in
 .Sq expert
 mode with the
 .Fl E
 option.
 .DFLT
 Empty string if
 .Sy USETOOLS=yes ;
 otherwise unset.
+.
 .It Sy EXTERNAL_TOOLCHAIN
 If defined, this variable indicates the root directory of
 an external toolchain which will be used to build the tree.
 For example, if a platform is a
 .Sy TOOLCHAIN_MISSING
 platform,
 .Sy EXTERNAL_TOOLCHAIN
 can be used to re-enable the cross-compile framework.
 .Pp
 If
 .Sy EXTERNAL_TOOLCHAIN
 is defined, act as
 .Sy MKGCC=no ,
 since the external version of the compiler may not be
 able to build the library components of the in-tree compiler.
 .Pp
 This variable should be used in conjunction with an appropriate
 .Sy HAVE_GCC
 or
 .Sy HAVE_LLVM
 setting to control the compiler flags.
 .Pp
 .Em Note :
 This variable is not yet used in as many places as it should be.
 Expect the exact semantics of this variable to change in the short
 term as parts of the cross-compile framework continue to be cleaned up.
 .DFLTu
+.
 .It Sy INSTALLBOOT_BOARDS
 A list of
 .Sy evbarm
 boards to create bootable images for.
 If corresponding U-Boot packages are installed,
 bootable images are created as part of a release.
 See the
 .Bk -words
 .Fl o Sy board= Ns Ar name
 .Ek
 option of
 .Xr installboot 8 .
 .DFLTu
+.
 .It Sy INSTALLWORLDDIR

 .DFLT
 .Dq Sy KERNSRCDIR Ns Pa / Ns Sy KERNARCHDIR Ns Pa /conf .
+.
 .It Sy KERNEL_DIR Pq No experimental
 .YorN
 Indicates if a top-level directory
 .Sy /netbsd/
 is created.
 If
 .Dq yes ,
 the directory will contain a kernel file
 .Pa /netbsd/kernel
 and a corresponding modules directory
 .Pa /netbsd/modules/ .
 System bootstrap procedures will be modified to search for the kernel
 and modules in the
 .Pa /netbsd/
 directory.
 This is intended to simplify system upgrade and rollback procedures by
 keeping the kernel and its associated modules together in one place.
 .Pp
 If
 .Dq no ,
 the kernel file will be stored in
 .Pa /netbsd
 and the modules will be stored within the
 .Pa /stand/${ARCH}/
 directory hierarchy.
 .Pp
 The
 .Sy KERNEL_DIR
 option is a work-in-progress, and is highly experimental.
 It is also subject to change without notice.
 .DFLTn

+.
 .It Sy MAKEVERBOSE
 Level of verbosity of status messages.
 Supported values:
 .Bl -tag -width 2n
 .It 0
 No descriptive messages or commands executed by
 .Xr make 1
 are shown.
 .It 1
 Brief messages are shown describing what is being done,
 but the actual commands executed by
 .Xr make 1
 are not shown.
 .It 2
 Descriptive messages are shown as above (prefixed with a
 .Sq # ) ,
 and ordinary commands performed by
 .Xr make 1
 are shown.
 .It 3
 In addition to the above, all commands performed by
 .Xr make 1
 are shown, even if they would ordinarily have been hidden
 through use of the
 .Dq \&@
 prefix in the relevant makefile.
 .It 4
 In addition to the above, commands executed by
 .Xr make 1
 are traced through use of the
 .Xr sh 1
 .Dq Fl x
 flag.
