      3 # This is the top-level makefile for building NetBSD. For an outline of
      4 # how to build a snapshot or release, as well as other release engineering
      5 .PHONY: release

      7 TARGETS+=      release

      9 # information, see http://www.netbsd.org/developers/releng/index.html
     10 #
     11 # Not everything you can set or do is documented in this makefile. In
     12 # particular, you should review the files in /usr/share/mk (especially
     13 # bsd.README) for general information on building programs and writing
     14 # Makefiles within this structure, and see the comments in src/etc/Makefile
     15 # for further information on installation and release set options.
     16 #
     17 # Variables listed below can be set on the make command line (highest
     18 # priority), in /etc/mk.conf (middle priority), or in the environment
     19 # (lowest priority).
     20 #
     21 # Variables:
     22 #   NBUILDJOBS is the number of jobs to start in parallel during a
     23 #	'make build'. It defaults to 1.
     24 #   MKMAN, if set to `no', will prevent building of manual pages.
     25 #   MKSHARE, if set to `no', will prevent building and installing
     26 #	anything in /usr/share.
     27 #   UPDATE will avoid a `make cleandir' at the start of `make build',
     28 #	as well as having the effects listed in /usr/share/mk/bsd.README.
     29 #   DESTDIR is the target directory for installation of the compiled
     30 #	software. It defaults to /. Note that programs are built against
     31 #	libraries installed in DESTDIR.
     32 #
     33 # Targets:
     34 #   build: builds a full release of netbsd in DESTDIR.
     35 #   release: does a `make build,' and then tars up the DESTDIR files
     36 #	into RELEASEDIR, in release(7) format. (See etc/Makefile for
     37 #	more information on this.)
     38 #   snapshot: a synonym for release.
