-.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.
+#   NBUILDJOBS is the number of jobs to start in parallel during a
+#	'make build'. It defaults to 1.
+#   UPDATE 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 will avoid a `make cleandir' at the start of `make build',
+#	but without having the effects listed in /usr/share/mk/bsd.README.
+#   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.)
+#   snapshot: a synonym for release.
+#
+# Sub targets of `make build,' in order:
+#   buildstartmsg: displays the start time of the build.
+#   beforeinstall: creates the distribution directories.
+#   do-force-domestic: check's that FORCE_DOMESTIC isn't set (deprecated.)
+#   do-share-mk: installs /usr/share/mk files.
+#   do-cleandir: clean's the tree.
+#   do-make-obj: create's object directories if required.
+#   do-check-egcs: check's that we have a modern enough compiler (deprecated.)
+#   do-make-includes: install include files.
+#   do-lib-csu: build & install startup object files.
+#   do-lib: build & install system libraries.
+#   do-gnu-lib: build & install gnu system libraries.
+#   do-dependall: builds & install the entire system.
+#   do-domestic: build & install the domestic tree (deprecated.)
+#   do-whatisdb: build & install the `whatis.db' man database.
+#   buildendmsg: displays the end time of the build.
