-.include <bsd.own.mk>			# for configuration variables.
+#
+# This is the top-level makefile for building NetBSD. For an outline of
+# how to build a snapshot or release, as well as other release engineering
+# information, see http://www.netbsd.org/developers/releng/index.html
+#
+# Not everything you can set or do is documented in this makefile. In
+# particular, you should review the files in /usr/share/mk (especially
+# bsd.README) for general information on building programs and writing
+# Makefiles within this structure, and see the comments in src/etc/Makefile
+# for further information on installation and release set options.
+#
+# Variables listed below can be set on the make command line (highest
+# priority), in /etc/mk.conf (middle priority), or in the environment
+# (lowest priority).
+#
+# Variables:
+#   DESTDIR is the target directory for installation of the compiled
+#	software. It defaults to /. Note that programs are built against
+#	libraries installed in DESTDIR.
+#   MKMAN, if set to `no', will prevent building of manual pages.
+#   MKOBJDIRS, if not set to `no', will build object directories at
+#	an appropriate point in a build.
+#   MKSHARE, if set to `no', will prevent building and installing
+#	anything in /usr/share.
+#   UPDATE, if defined, will avoid a `make cleandir' at the start of
+#	`make build', as well as having the effects listed in
+#	/usr/share/mk/bsd.README.
+#   NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
+#	of the `make build'.
+#   NOINCLUDES will avoid the `make includes' usually done by `make build'.
+#
+# Targets:
+#   build:
+#	Builds a full release of NetBSD in DESTDIR.  If BUILD_DONE is
+#	set, this is an empty target.
+#   release:
+#	Does a `make build,' and then tars up the DESTDIR files
+#	into RELEASEDIR, in release(7) format. (See etc/Makefile for
+#	more information on this.)
+#   regression-tests:
+#	Runs the regression tests in "regress" on this host.
+#
+# Targets invoked by `make build,' in order:
+#   cleandir:        cleans the tree.
+#   obj:             creates object directories.
+#   do-tools:        builds host toolchain.
+#   do-distrib-dirs: creates the distribution directories.
+#   includes:        installs include files.
+#   do-lib-csu:      builds and installs prerequisites from lib/csu.
+#   do-lib-libc:     builds and installs prerequisites from lib/libc.
+#   do-lib:          builds and installs prerequisites from lib.
+#   do-gnu-lib:      builds and installs prerequisites from gnu/lib.
+#   do-ld.so:        builds and installs prerequisites from libexec/ld.*_so.
+#   do-build:        builds and installs the entire system.
