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.
