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

7TARGETS+=      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.
