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#   EXPORTABLE_SYSTEM, when set, ensures that non-exportable crypto code
29#	is not compiled or installed. EXPORTABLE_SYSTEM is ignored if
30#	the `domestic' subtree does not exist.
31#   FORCE_DOMESTIC, when set, forces a descent into the domestic tree
32#	when handling the `all', `includes', and `install' targets. This
33#	flag is incompatible with the `build' target. It's generally a
34#	bad idea to use FORCE_DOMESTIC unless the ramifications are well
35#	understood, and should never be enabled by default. FORCE_DOMESTIC
36#	is ignored if the `domestic' subtree does not exist.
37#
38# Targets:
39#   build: builds a full release of netbsd in DESTDIR.
40#   release: does a `make build,' and then tars up the DESTDIR files
41#	into RELEASEDIR, in release(7) format. (See etc/Makefile for
42#	more information on this.)
43#   snapshot: a synonym for release.
