Makefile revision 1.95.2.2 
1#	$NetBSD: Makefile,v 1.95.2.2 2000/09/09 16:29:26 he Exp $

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# information, see http://www.netbsd.org/developers/releng/index.html
6#
7# Not everything you can set or do is documented in this makefile. In
8# particular, you should review the files in /usr/share/mk (especially
9# bsd.README) for general information on building programs and writing
10# Makefiles within this structure, and see the comments in src/etc/Makefile
11# for further information on installation and release set options.
12#
13# Variables listed below can be set on the make command line (highest
14# priority), in /etc/mk.conf (middle priority), or in the environment
15# (lowest priority).
16#
17# Variables:
18#   NBUILDJOBS is the number of jobs to start in parallel during a
19#	'make build'. It defaults to 1.
20#   MKMAN, if set to `no', will prevent building of manual pages.
21#   MKSHARE, if set to `no', will prevent building and installing
22#	anything in /usr/share.
23#   UPDATE will avoid a `make cleandir' at the start of `make build',
24#	as well as having the effects listed in /usr/share/mk/bsd.README.
25#   DESTDIR is the target directory for installation of the compiled
26#	software. It defaults to /. Note that programs are built against
27#	libraries installed in DESTDIR.
28#
29# Targets:
30#   build: builds a full release of netbsd in DESTDIR.
31#   release: does a `make build,' and then tars up the DESTDIR files
32#	into RELEASEDIR, in release(7) format. (See etc/Makefile for
33#	more information on this.)
34#   snapshot: a synonym for release.
