+			       bmake
+
+This directory contains a port of the BSD make tool (from NetBSD)
+I have run it on SunOS,Solaris,HP-UX,AIX,IRIX,FreeBSD and Linux.
+
+Version 3 was re-worked from scratch to better facilitate
+importing newer make(1) versions from NetBSD.  The original code base
+was NetBSD-1.0, so version 3 was built by doing a fresh import of the
+NetBSD-1.0 usr.bin/make, adding the autoconf and other portability
+patches to sync it with bmake v2, and then NetBSD's make 
+of Feb 20, 2000 was imported and conflicts dealt with.
+NetBSD's make was again imported on June 6 and December 15, 2000.
+
+In 2003 bmake switched to a date based version (first was 20030714)
+which generally represents the date it was last merged with NetBSD's
+make.  Since then, NetBSD's make is imported within a week of any
+interesting changes, so that bmake tracks it very closely.
+
+Building:
+
+The preferred way to bootstrap bmake is:
+
+./bmake/boot-strap
+
+there are a number of args - most of which get passed to configure,
+eg.
+
+./bmake/boot-strap --prefix=/opt
+
+see the boot-strap script for details.
+
+To make much use of bmake you will need the bsd.*.mk macros or my
+portable *.mk macros.  See 
+http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
+which will be links to the latest versions.
+
+On a non-BSD system, you would want to unpack mk[-YYYYmmdd].tar.gz in
+the same directory as bmake (so ./mk and ./bmake exist), and
+./bmake/boot-strap will do the rest.
+
+If you want to do it all by hand then read boot-strap first to get the
+idea.
+
+Even if you have an earlier version of bmake installed, use boot-strap
+to ensure that all goes well.

+# NAME:
+#	boot-strap
+#
+# SYNOPSIS:
+#	boot-strap ["options"]
+#	boot-strap --prefix=/opt --install
+#	boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
+#	boot-strap ["options"] op=build
+#	boot-strap ["options"] op=install
+#
+# DESCRIPTION:
+#	This script is used to configure/build bmake it builds for
+#	each host-target in a different subdir to keep the src clean.
+#	There is no requirement for an existing make(1).
+#
+#	On successful completion if no '--install' flag is given,
+#	it echos a command to do installation.
+#
+#	The variable "op" defaults to 'all', and is affected by
+#	'--install' flag as above.
+#	Other values include:
+#
+#	configure
+#		Just run 'configure'
+#
+#	build
+#		If 'configure' has not been done, do it, then
+#		run the build script, and finally 'test'.
+#
+#	install
+#		If 'build' has not been done, do it, 'test' then
+#		install. 
+#
+#	clean
+#		attempt to clean up
+#
+#	test
+#		run the unit-tests.  Done automatically after 'build'
+#		and before 'install'.
+#
+#	The above are leveraged by a trivial makefile for the benefit
+#	of those that have './configure; make; make install' baked
+#	into them.
+#	
+#	Options:
+#
+#	-c "rc"
+#		Pick up settings from "rc".  
+#		We look for '.bmake-boot-strap.rc' before processing
+#		options (unless SKIP_RC is set in environment).
+#
+#	--share "share_dir"
+#		Where to put man pages and mk files.
+#		If $prefix ends in $HOST_TARGET, and $prefix/../share
+#		exits, the default will be that rather than $prefix/share.
+#
+#	--mksrc "mksrc"
+#		Indicate where the mk files can be found.
+#		Default is $Mydir/mk
+#
+#	--install
+#		If build and test work, run bmake install.
+#		BINDIR=$prefix/bin
+#		SHAREDIR=$prefix/share
+#
+#	--install-host-target
+#		As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
+#		This is useful when $prefix/ is shared by multiple
+#		machines.
+#
+#	Flags relevant when installing:
+#
+#	-DWITHOUT_INSTALL_MK
+#		Skip installing mk files.
+#		By default they will be installed to $prefix/share/mk
+#
+#	-DWITH_PROG_VERSION
+#		Install 'bmake' as 'bmake-$MAKE_VERSION'
+#		A symlink will be made as 'bmake' unless
+#		-DWITHOUT_PROG_LINK is set.
+#
+#	Possibly useful configure_args:
+#
+#	--without-meta
+#		disable use of meta mode.
+#
+#	--without-filemon
+#		disable use of filemon(9) which is currently only
+#		available for NetBSD and FreeBSD.
+#
+#	--with-filemon="path/to/filemon.h"
+#		enables use of filemon(9) by meta mode.
+#		
+#	--with-machine="machine"
+#		set "machine" to override that determined by
+#		machine.sh
+#	
+#	--with-force-machine="machine"
+#		force "machine" even if uname(3) provides a value.
+#
+#	--with-machine_arch="machine_arch"
+#		set "machine_arch" to override that determined by
+#		machine.sh
+#
+#	--with-default-sys-path="syspath"
+#		set an explicit default "syspath" which is where bmake
+#		will look for sys.mk and friends.

+# NAME:
+#	install.sh - portable version of install(1)
+#
+# SYNOPSIS:
+#	install [-CNcs] [-f flags] [-i errs] [-o owner] [-g group] [-m mode] file1 file2 ...
+#	install -d  [-i errs] [-o owner] [-g group] [-m mode] directory ...
+#
+# DESCRIPTION:
+#	Compatible with BSD install(1).  Except that '-c' is always
+#	true and we always move an already installed target aside as
+#	this is important on many systems.  Recent BSD install(1)
+#	versions have a '-b' option for this.
+#	
+#
+# OPTIONS:
+#	-b	move previous target file aside (always true).
+#
+#	-B "suffix"
+#		use "suffix" instead of .old for saving existing target.
+#	
+#	-c	copy rather than move the file into place (always true).
+#
+#	-C	compare.  Only install if target is missing or
+#		different.
+#
+#	-N	newer. Only install if target is missing or older.
+#	
+#	-s	strip target
+#
+#	-o "owner"
+#		make target owned by "owner"
+#
+#	-g "group"
+#		make target group owned by "group"
+#
+#	-m "mode"
+#		set permissions to "mode"
+#
+#	-f "flags"
+#		Pass "flags" onto chflags(1)
+#		
+#	-i "errs"
+#		Ignore errors from steps indicated by "errs" (``s,o,g,m'').
+#
+# BUGS:
+#	The '-i' option is to save your sanity when 'bsd.prog.mk'
+#	insists on haveing a '-o' "owner" option which is doomed to
+#	fail on many systems.  We ignore '-b', '-B' and '-c' options.

+ * Shell Specifications:
+ * Each shell type has associated with it the following information:
+ *	1) The string which must match the last character of the shell name
+ *	   for the shell to be considered of this type. The longest match
+ *	   wins.
+ *	2) A command to issue to turn off echoing of command lines
+ *	3) A command to issue to turn echoing back on again
+ *	4) What the shell prints, and its length, when given the echo-off
+ *	   command. This line will not be printed when received from the shell
+ *	5) A boolean to tell if the shell has the ability to control
+ *	   error checking for individual commands.
+ *	6) The string to turn this checking on.
+ *	7) The string to turn it off.
+ *	8) The command-flag to give to cause the shell to start echoing
+ *	   commands right away.
+ *	9) The command-flag to cause the shell to Lib_Exit when an error is
+ *	   detected in one of the commands.
+ *
+ * Some special stuff goes on if a shell doesn't have error control. In such
+ * a case, errCheck becomes a printf template for echoing the command,
+ * should echoing be on and ignErr becomes another printf template for
+ * executing the command while ignoring the return status. Finally errOut
+ * is a printf template for running the command and causing the shell to 
+ * exit on error. If any of these strings are empty when hasErrCtl is FALSE, 
+ * the command will be executed anyway as is and if it causes an error, so be 
+ * it. Any templates setup to echo the command will escape any '$ ` \ "'i
+ * characters in the command string to avoid common problems with 
+ * echo "%s\n" as a template.

+2015-04-16  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20150411
+	  bump version
+	
+	* own.mk: put AUTO_OBJ in OPTIONS_DEFAULT_NO rather than YES.
+	  it is here mainly for documentation purposes, since
+	  if using auto.obj.mk it is better done via sys.mk
+
+2015-04-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20150401
+	
+	* meta2deps.sh: support @list
+	
+	* meta2deps.py: updates from Juniper
+	  o add EXCLUDES 
+	  o skip bogus input files.
+	  o treat 'M' and 'L' as both an 'R' and a 'W'
+
+2015-03-03  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20150303
+	
+	* dirdeps.mk: if MK_DIRDEPS_CACHE is yes, use dirdeps-cache
+	  which is built via sub-make so we have a .meta file to tell if
+	  it is out-of-date. 
+	  The dirdeps-cache contains the same dependency rules that we
+	  normaly construct on the fly.
+	  This adds a few seconds overhead when the cache is out of date,
+	  but for a large target, the savings can be significant (10-20min).
+
+2014-11-18  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20141118
+	
+	* meta.stage.mk: add stale_staged
+	
+	* dirdeps.mk (_DIRDEP_USE_LEVEL): allow this to be tweaked
+	  only useful under very rare conditions such as
+	  FreeBSD's make universe.
+
+	* auto.obj.mk: Allow MK_AUTO_OBJ to set MKOBJDIRS=auto
+	
+2014-11-11  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20141111
+
+	* mkopt.sh: use consistent semantics for _mk_opt and _mk_opts
+
+2014-11-09  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* FILES: include mkopt.sh which allows handling options in shell
+	  scripts in a manner compatible with options.mk
+
+2014-10-12  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk: ensure only _STAGED_DIRS under objroot are used
+	  for GENDIRDEPS_FILTER to avoid surprises.
+
+2014-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+	
+	* dirdeps.mk (NSkipHostDir): this needs SRCTOP prepended since by
+	  the time it is applied to __depdirs they have.
+	
+	* dirdeps.mk fix filtering of _machines since M_dep_qual_fixes
+	  expects patterns like *.${MACHINE}
+	
+	* cython.mk (pyprefix?): use pyprefix to find python bits
+	  since prefix might be something else (where we install our
+	  stuff)
+	
+2014-09-11  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20140911
+	
+	* dirdeps.mk: add bootstrap target to simplify adding support for
+	  new MACHINE.
+	
+2014-09-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* gendirdeps.mk: Add handling of GENDIRDEPS_FILTER_DIR_VARS and
+	  GENDIRDEPS_FILTER_VARS to make it easier to produce sharable
+	  Makefile.depend files.
+
+2014-08-28  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20140828
+	
+	* cython.mk: capture logic for building python extension modules
+	  with Cython.
+
+2014-08-08  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk (_STAGE_AS_BASENAME_USE): Add StageAs variant
+
+2014-08-02  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20140801
+
+	* dep.mk: use explicit MKDEP_MK rather than overload MKDEP to
+	identify the autodep.mk variant. 
+	
+	* sys.dependfile.mk: delete .MAKE.DEPENDFILE if its
+	initial value does not match .MAKE.DEPENDFILE_PREFIX
+
+	* meta.autodep.mk: if _bootstrap_dirdeps add RELDIR to DIRDEPS
+
+2014-05-22  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20140522
+
+	* lib.mk: use CC to link shlib for linux too
+	  patch from Brendan MacDonell
+
+2014-05-05  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.autodep.mk: add _reldir_{finish,failed} for gathering stats
+	  if WITH_META_STATS is defined.
+
+2014-05-02  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* dirdeps.mk: accept -DWITHOUT_DIRDEPS (same a as -DNO_DIRDEPS)
+	  to supress dirdeps outside of .CURDIR.
+
+2014-04-05  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* Fix spelling errors - patch from Pedro Giffuni
+
+2014-03-14  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20140314
+
+	* dirdeps.mk (beforedirdeps): a handy hook
+
+	* dirdeps.mk (DIRDEP_MAKE): allow the actual command we run
+	  to visit leaf dirs to be intercepted (eg. for distributed
+	  build).
+
+	* dirdeps.mk (__depdirs): ensure // don't sneak in
+	
+	* gendirdeps.mk (DIRDEPS): ensure // don't sneak in
+
+
+2014-02-21  Simon J. Gerraty  <sjg@bad.crufty.net>

+
+2014-02-14  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version

+2014-02-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* options.mk: avoid :U so this isn't bmake dependent
+
+2014-02-09  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* options.mk: cleanup and simplify semanitcs 
+	  NO_* dominates all, if both WITH_* and WITHOUT_*
+	  are defined then result is DOMINATE_* which defaults to "no".
+	  Ie. WITHOUT_ normally wins.
+
+2013-12-12  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version
+	* meta2deps.py: convert to print function for python3 compat.
+	  we also need to open files with mode 'r' rather than 'rb'
+	  otherwise we get bytes instead of strings.
+
+2013-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version
+
+	* dirdeps.mk: when TARGET_SPEC_VARS is more than just MACHINE
+	  apply the same filtering (M_dep_qual_fixes) when setting _machines
+	  as _build_dirs.
+	  Also fix the filtering of Makefile.depend files - for reporting
+	  what we are looking for (M_dep_qual_fixes can get confused by
+	  Makefile.depend) 
+	  Add some more debug info.
+
+2013-09-04  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* gendirdeps.mk (_objtops): fix typo also
+	  while processing M2D_OBJROOTS to gather qualdir_list
+	  qualify $ql with loop iterator to ensure correct results.
+
+2013-08-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20130801
+	* libs.mk: update to match progs.mk
+	
+2013-07-26  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20130726
+	  some updates from Juniper and FreeBSD
+	  o meta2deps.py: indicate file and line number when we hit parse
+	    errors
+	    also allow @file to provide huge list of .meta files.
+	* meta2deps.py: add try_parse() to cleanup the above.
+	
+2013-07-16  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20130716
+	* own.mk: add GPROG as an option
+	* prog.mk: honor MK_GPROF==yes
+	
+2013-05-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20130505
+	* gendirdeps.mk, meta2deps.py, meta2deps.sh: handle $TARGET_SPEC
+	  for when $MACHINE isn't enough for objdir distinction.
+	  Bring meta2deps.sh closer to par with meta2deps.py.
+
+2013-04-18  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all'
+	  also if the target 'beforeinstall' exists, make it depend on
+	  .dirdep (incase it uses STAGE_INSTALL).
+
+2013-04-17  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): 20130401 ;-)
+	* meta.stage.mk (STAGE_INSTALL_SH): add stage-install.sh as
+	  wrapper around install(1).
+	* options.mk (OPTION_PREFIX): Allow a prefix other than MK_
+
+2013-03-30  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta2deps.py (MetaFile.__init__): ensure self.cwd is initialized.
+	* install-mk (MK_VERSION): bump version
+
+2013-03-21  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version
+	* gendirdeps.mk: do not apply :tA to DPADD entries, since we lose
+	  any trailing /., rather apply :tA only when needed.
+	* gendirdeps.mk: better mimic meta2deps handling of .dirdep files.
+	* meta.stage.mk (LN_CP_SCRIPT): Add LnCp to do the ln||cp dance
+	  consistently.
+	* dirdeps.mk: better describe the dance in sys.mk for TARGET_SPEC.
+	
+2013-03-18  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* gendirdeps.mk: revert the dance around .MAKE.DEPENDFILE_DEFAULT
+	  it is simpler to just not update when say building for "host"
+	  (where we know we apply filters to DIRDEPS), and using a
+	  non-machine qualified dependfile.
+
+2013-03-16  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* dirdeps.mk: improve DIRDEPS filtering by allowing DEP_SKIP_DIR
+	  and DEP_DIRDEPS_FILTER to vary by DEP_MACHINE and DEP_TARGET_SPEC
+	* gendirdeps.mk: ensure _objroot has trailing / if it needs it.
+	* meta2deps.py: if machine is "host", then also trim
+	  self.host_target from any OBJROOTS.
+	
+
+2013-03-11  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* gendirdeps.mk: if .MAKE.DEPENDFILE_DEFAULT is not machine
+	  qualified but _DEPENDFILE is, and .MAKE.DEPENDFILE_DEFAULT exists
+	  but _DEPENDFILE does not, compare the new _DEPENDFILE against
+	  .MAKE.DEPENDFILE_DEFAULT and discard if the same.
+
+2013-03-08  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk: use STAGE_TARGETS to control .ORDER
+	  and hook to all: via staging:
+
+2013-03-07  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* sys.dependfile.mk (.MAKE.DEPENDFILE_DEFAULT): 
+	  use a separate variable for the default .MAKE.DEPENDFILE value
+	  so that it can be controlled independently of
+	  .MAKE.DEPENDFILE_PREFERENCE
+
+	* meta.stage.mk: throw error if cp fails etc.
+	  Stage*() return early if passed no args.
+	  .ORDER stage_*
+
+2013-03-03  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version
+	* gendirdeps.mk: handle multiple M2D_OBJROOTS better.
+
+2013-02-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20130210
+	* import latest dirdeps.mk, gendirdeps.mk and meta2deps.py 
+	  from Juniper. 
+	  o dirdeps.mk now fully supports TARGET_SPEC consisting of more
+	    than just MACHINE.
+	  o no longer use DEP_MACHINE from Makefile.depend* so remove it.
+	
+2013-01-23  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20130123
+	* meta.stage.mk: add stage_links (hard links).
+	  if doing hard links, we add dest to link as well.
+	  Default the stage dir for [sym]links to STAGE_OBJTOP since
+	  these are typically specified as absolute paths.
+	  Add -m "mode" flag to StageFiles and StageAs.
+
+2012-11-11  Simon J. Gerraty  <sjg@bad.crufty.net>
+

+	* meta.autodep.mk: pass resolved MAKESYSPATH to gendirdeps
+	  in case we were found via .../mk
+	* sys.clean-env.mk: move it from examples, we and others use it
+	  "as is".
+	* FILES: add srctop.mk and options.mk
+	* own.mk: convert to using options.mk
+	  which is modeled after FreeBSD's handling of MK_*
+	  but more flexible.
+	  This allows MK_* for boolean knobs to not be confused
+	  with MK* which can be commands.
+
+	* examples/sys.clean-env.mk: add WITH[OUT]_ to
+	  MAKE_ENV_SAVE_PREFIX_LIST.
+	  Mention that HOME=/var/empty might be a good idea.
+
+2012-11-08  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* sys.dependfile.mk: if not depend file exists, $MACHINE
+	  specific ones are supported but not the default,
+	  check if any exist and follow suit.
+
+2012-11-06  Simon J. Gerraty  <sjg@bad.crufty.net>

+	  appropriate.
+	
+2012-11-04  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk: update CLEANFILES
+	  remove redundant cp of .dirdep from STAGE_AS_SCRIPT.

+	
+2012-10-12  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk (STAGE_DIR_FILTER): track dirs we stage to in
+	  _STAGED_DIRS so that these can be turned into filters for
+	  GENDIRDEPS_FILTER.
+
+2012-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20121010

+	
+2012-06-26  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20120626
+	* meta.sys.mk: ignore PYTHON if it does not exist
+	  compare ${.MAKE.DEPENDFILE:E} against ${MACHINE} is more reliable.
+	* meta.stage.mk: examine .MAKE.DEPENDFILE_PREFERENCE for any
+	  entries ending in .${MACHINE} to decide if qualified _dirdep is
+	  needed.
+	* gendirdeps.mk: only produce unqualified deps if no
+	  .MAKE.DEPENDFILE_PREFERENCE ends in .${MACHINE}
+	* meta.subdir.mk: apply SUBDIREPS_FILTER
+	
+2012-04-20  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20120420
+	* add sys.dependfile.mk so we can experiment with
+	  .MAKE.DEPENDFILE_PREFERENCE 
+	* meta.autodep.mk: _DEPENDFILE is precious!
+	
+2012-03-15  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20120315
+	* install-new.mk: avoid being interrupted
+
+2012-02-26  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* man.mk: MAN might have multiple values so be careful with exists().
+
+2012-01-19  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20120112
+	* fix examples/sys.clean-env.mk so that MAKEOBJDIR is handled
+	  as: MAKEOBJDIR='${.CURDIR:S,${SRCTOP},${OBJTOP},}'
+
+2011-12-03  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION):  bump version to 20111201
+	* import dirdeps.mk from Juniper sjg@
+	  o more consistent handling of DEP_MACHINE, especially when
+	    dealing with an odd Makefile.depend, when normally using
+	    Makefile.depend.${MACHINE}
+
+2011-11-22  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20111122
+	* meta.autodep.mk: add some debug output, be more crisp about
+	  updating.  Use ${.ALLTARGETS:M*.o} as a clue for .depend
+
+2011-11-13  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20111111
+	  it's too cool to miss
+	* import meta* updates from Juniper sjg@
+	  o dirdeps.mk set DEP_MACHINE for Makefile.depend (when we are
+	    normally using Makefile.depend.${MACHINE}), handy for
+	    read-only manually maintained dependencies.
+	  o meta2deps.py add a clear 'ERROR:' token if an exception is raised.
+	  o gendirdeps.mk if ERROR: from meta2deps.py do not update
+	    anything.
+	
+2011-10-30  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-new.mk separate the cmp and copy logic to its own function.

+2011-10-28  Simon J. Gerraty  <sjg@bad.crufty.net>
+

+2011-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20111010

+2011-10-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20111001

+	* autoconf.mk: add autoconf-input as a hook for regenerating 
+	  AUTOCONF_INPUTS (configure).
+
+2011-08-24  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.autodep.mk: if we do not have OBJS, .depend isn't a useful
+	  trigger for updating Makefile.depend* 
+
+2011-08-08  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20110808
+	* obj.mk: minor cleanup
+	* auto.obj.mk: improve description of Mkdirs and honor NO_OBJ too.
+
+2011-08-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* auto.obj.mk (.OBJDIR): throw an error if we cannot use the
+	  specified dir.
+
+2011-06-28  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.autodep.mk: if XMAKE_META_FILE is set
+	  the makefile uses a foreign make, and so dependencies
+	  can only be gathered from a clean tree build.
+
+2011-06-24  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20110622

+2011-06-04  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20110606
+	* don't store SRC_DIRDEPS in Makefile.depend* by default
+	  not everyone needs it.
+
+2011-05-04  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20110505

+2011-04-03  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* rst2htm.mk: convert rst to s5 (slides) or plain html depending

+
+2011-03-29  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* sys.mk (_DEBUG_MAKE_FLAGS): use indirection so that DEBUG_MAKE_FLAGS0
+	  can be used to debug level 0 only and DEBUG_MAKE_FLAGS for the rest.
+	* sys.mk: re-define M_whence in terms of M_type.
+	  M_type is useful for checking if something is a builtin.
+	
+2011-03-16  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.stage.mk: add stage_symlinks and leverage StageLinks for
+	  stage_libs 
+
+2011-03-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* dirdeps.mk: correct value for _depdir_files depends on
+	  .MAKE.DEPENDFILE 
+	  Add our copyright - just to make it clear we have frobbed this
+	  quite a bit.
+	  DEP_MACHINE needs to be set to MACHINE each time, if using only
+	  Makefile.depend (cf. Makefile.depend.${MACHINE})
+
+	* meta.stage.mk: meta mode version of staging
+
+	* init.mk, final.mk: include local.*.mk to simplify customization
+
+2011-03-03  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* auto.obj.mk: just because we are doing mk destroy, we should
+	  still set .OBJDIR correctly if it exists.
+
+	* install-mk (mksrc): do not exclude meta.sys.mk
+
+2011-03-01  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* host-target.mk: set/export _HOST_ARCH etc separately,
+	  catch junk resulting from uname -p, so we can find sys/Linux.mk
+	  correctly.
+
+2011-02-18  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* meta.sys.mk: throw an error if /dev/filemon is missing and we
+	  expected to be updating Makefile.depend*
+
+2011-02-14  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20110214

+
+2010-09-25  Simon J. Gerraty  <sjg@bad.crufty.net>

+2010-09-24  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20100919
+	include dirdeps.mk et al from Juniper Networks, 
+	for meta mode - requires filemon(9).
+	* sys.mk, subdir.mk: Add hooks for meta mode.

+	* lib.mk: remove duplicate addition to SOBJS
+
+2010-06-10  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* sys.mk: Add a means of selectively turning on debug flags.
+	  Eg. DEBUG_MAKE_FLAGS=-dv DEBUG_MAKE_DIRS="*lib/sjg"
+	  will act as if we did make -dv if .CURDIR ends in lib/sjg
+	  DEBUG_MAKE_SYS_DIRS does the same thing, but we set the flags at
+	  the start of sys.mk rather than the end.
+	  This only makes sense for leaf dirs, so we check that
+	  .MAKE.LEVEL > 0
+
+2010-06-09  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20100608
+	* sys.mk: include sys.env.mk later so it can use M_ListToSkip et al.
+	* examples/sys.clean-env.mk: require MAKE_VERIONS >= 20100606

+
+2010-05-13  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* sys.mk (M_tA): better simulate the result of :tA if not available.
+
+2010-05-04  Simon J. Gerraty  <sjg@bad.crufty.net>

+	  asked to do that.
+	  fix/simplify the tests for when to run mkdep.
+	* auto.dep.mk: add some explanation of how/what we do.
+	* autodep.mk: skip the .OPTIONAL frobbing of .depend
+	  bmake's FROM_DEPEND flag makes it redundant.
+	
+2010-04-13  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* install-mk (MK_VERSION): bump version to 20100404
+	* subdir.mk: protect from multiple inclusion using _SUBDIRUSE.
+	* obj.mk: protect from multiple inclusion even as bsd.obj.mk

+	subdir.mk
+
+2010-04-12  Simon J. Gerraty  <sjg@bad.crufty.net>
+
+	* dep.mk: use <> when .including so can override.

+
+2009-12-11  Simon J. Gerraty  <sjg@void.crufty.net>

+
+2009-12-10  Simon J. Gerraty  <sjg@void.crufty.net>
+
+	* FILES: move all the platform *.sys.mk files to sys/*.mk
+	* Rename Generic.sys.mk to sys.mk - we always want it.
+
+2009-11-17  Simon J. Gerraty  <sjg@void.crufty.net>
+
+	* install-mk (MK_VERSION): bump version
+	* host-target.mk: only export the expensive stuff 
+	* Generic.sys.mk (sys_mk): for SunOS we need to look for

+
+2009-11-07  Simon J. Gerraty  <sjg@void.crufty.net>
+

+
+2007-02-16  Simon J. Gerraty  <sjg@void.crufty.net>

+
+This directory contains some macro's derrived from the NetBSD bsd.*.mk
+macros.  They have the same names but without the bsd., separate macro
+files are needed to ensure we can make them do what we want for
+builing things outside of /usr/src.  Nearly all the comments below
+apply. 
+
+#	$NetBSD: bsd.README,v 1.18 1997/01/13 00:54:23 mark Exp $
+#	@(#)bsd.README	5.1 (Berkeley) 5/11/90
+
+This is the README file for the new make "include" files for the BSD
+source tree.  The files are installed in /usr/share/mk, and are, by
+convention, named with the suffix ".mk".
+
+Note, this file is not intended to replace reading through the .mk
+files for anything tricky.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+RANDOM THINGS WORTH KNOWING:
+
+The files are simply C-style #include files, and pretty much behave like
+you'd expect.  The syntax is slightly different in that a single '.' is
+used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
+
+One difference that will save you lots of debugging time is that inclusion
+of the file is normally done at the *end* of the Makefile.  The reason for
+this is because .mk files often modify variables and behavior based on the
+values of variables set in the Makefile.  To make this work, remember that
+the FIRST target found is the target that is used, i.e. if the Makefile has:
+
+	a:
+		echo a
+	a:
+		echo a number two
+
+the command "make a" will echo "a".  To make things confusing, the SECOND
+variable assignment is the overriding one, i.e. if the Makefile has:
+
+	a=	foo
+	a=	bar
+
+	b:
+		echo ${a}
+
+the command "make b" will echo "bar".  This is for compatibility with the
+way the V7 make behaved.
+
+It's fairly difficult to make the BSD .mk files work when you're building
+multiple programs in a single directory.  It's a lot easier split up the
+programs than to deal with the problem.  Most of the agony comes from making
+the "obj" directory stuff work right, not because we switch to a new version
+of make.  So, don't get mad at us, figure out a better way to handle multiple
+architectures so we can quit using the symbolic link stuff.  (Imake doesn't
+count.)
+
+The file .depend in the source directory is expected to contain dependencies
+for the source files.  This file is read automatically by make after reading
+the Makefile.
+
+The variable DESTDIR works as before.  It's not set anywhere but will change
+the tree where the file gets installed.
+
+The profiled libraries are no longer built in a different directory than
+the regular libraries.  A new suffix, ".po", is used to denote a profiled
+object.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <sys.mk> has the default rules for all makes, in the BSD
+environment or otherwise.  You probably don't want to touch this file.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.man.mk> handles installing manual pages and their
+links.
+
+It has a single target:
+
+	maninstall:
+		Install the manual pages and their links.
+
+It sets/uses the following variables:
+
+MANDIR		Base path for manual installation.
+
+MANGRP		Manual group.
+
+MANOWN		Manual owner.
+
+MANMODE		Manual mode.
+
+MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
+		or "/tahoe" for machine specific manual pages.
+
+MAN		The manual pages to be installed (use a .1 - .9 suffix).
+
+MLINKS		List of manual page links (using a .1 - .9 suffix).  The
+		linked-to file must come first, the linked file second,
+		and there may be multiple pairs.  The files are soft-linked.
+
+The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
+it exists.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.own.mk> contains source tree configuration parameters,
+such as the owners, groups, etc. for both manual pages and binaries, and
+a few global "feature configuration" parameters.
+
+It has no targets.
+
+To get system-specific configuration parameters, bsd.own.mk will try to
+include the file specified by the "MAKECONF" variable.  If MAKECONF is not
+set, or no such file exists, the system make configuration file, /etc/mk.conf
+is included.  These files may define any of the variables described below.
+
+bsd.own.mk sets the following variables, if they are not already defined
+(defaults are in brackets):
+
+BSDSRCDIR	The real path to the system sources, so that 'make obj'
+		will work correctly. [/usr/src]
+
+BSDOBJDIR	The real path to the system 'obj' tree, so that 'make obj'
+		will work correctly. [/usr/obj]
+
+BINGRP		Binary group. [bin]
+
+BINOWN		Binary owner. [bin]
+
+BINMODE		Binary mode. [555]
+
+NONBINMODE	Mode for non-executable files. [444]
+
+MANDIR		Base path for manual installation. [/usr/share/man/cat]
+
+MANGRP		Manual group. [bin]
+
+MANOWN		Manual owner. [bin]
+
+MANMODE		Manual mode. [${NONBINMODE}]
+
+LIBDIR		Base path for library installation. [/usr/lib]
+
+LINTLIBDIR	Base path for lint(1) library installation. [/usr/libdata/lint]
+
+LIBGRP		Library group. [${BINGRP}]
+
+LIBOWN		Library owner. [${BINOWN}]
+
+LIBMODE		Library mode. [${NONBINMODE}]
+
+DOCDIR		Base path for system documentation (e.g. PSD, USD, etc.)
+	        installation. [/usr/share/doc]
+
+DOCGRP		Documentation group. [bin]
+
+DOCOWN		Documentation owner. [bin]
+
+DOCMODE		Documentation mode. [${NONBINMODE}]
+
+NLSDIR		Base path for National Language Support files installation.
+		[/usr/share/nls]
+
+NLSGRP		National Language Support files group. [bin]
+
+NLSOWN		National Language Support files owner. [bin]
+
+NLSMODE		National Language Support files mode. [${NONBINMODE}]
+
+STRIP		The flag passed to the install program to cause the binary
+		to be stripped.  This is to be used when building your
+		own install script so that the entire system can be made
+		stripped/not-stripped using a single knob. [-s]
+
+COPY		The flag passed to the install program to cause the binary
+		to be copied rather than moved.  This is to be used when
+		building our own install script so that the entire system
+		can either be installed with copies, or with moves using
+		a single knob. [-c]
+
+Additionally, the following variables may be set by bsd.own.mk or in a
+make configuration file to modify the behaviour of the system build
+process (default values are in brackets along with comments, if set by
+bsd.own.mk):
+
+EXPORTABLE_SYSTEM
+		Do not build /usr/src/domestic, even if it is present.
+
+SKEY		Compile in support for S/key authentication. [yes, set
+		unconditionally]
+
+KERBEROS	Compile in support for Kerberos 4 authentication.
+
+KERBEROS5	Compile in support for Kerberos 5 authentication.
+
+MANZ		Compress manual pages at installation time.
+
+SYS_INCLUDE	Copy or symlink kernel include files into /usr/include.
+		Possible values are "symlinks" or "copies" (which is
+		the same as the variable being unset).
+
+NOPROFILE	Do not build profiled versions of system libraries
+
+NOPIC		Do not build PIC versions of system libraries, and
+		do not build shared libraries.  [set if ${MACHINE_ARCH}
+		is "mips", "vax", "alpha" or "arm32", unset otherwise.]
+
+NOLINT		Do not build lint libraries. [set, set unconditionally]
+
+bsd.own.mk is generally useful when building your own Makefiles so that
+they use the same default owners etc. as the rest of the tree.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.prog.mk> handles building programs from one or
+more source files, along with their manual pages.  It has a limited number
+of suffixes, consistent with the current needs of the BSD tree.
+
+It has eight targets:
+
+	all:
+		build the program and its manual page
+	clean:
+		remove the program, any object files and the files a.out,
+		Errs, errs, mklog, and core.
+	cleandir:
+		remove all of the files removed by the target clean, as
+		well as .depend, tags, and any manual pages.
+	depend:
+		make the dependencies for the source files, and store
+		them in the file .depend.
+	includes:
+		install any header files.
+	install:
+		install the program and its manual pages; if the Makefile
+		does not itself define the target install, the targets
+		beforeinstall and afterinstall may also be used to cause
+		actions immediately before and after the install target
+		is executed.
+	lint:
+		run lint on the source files
+	tags:
+		create a tags file for the source files.
+
+It sets/uses the following variables:
+
+BINGRP		Binary group.
+
+BINOWN		Binary owner.
+
+BINMODE		Binary mode.
+
+CLEANFILES	Additional files to remove for the clean and cleandir targets.
+
+COPTS		Additional flags to the compiler when creating C objects.
+
+HIDEGAME	If HIDEGAME is defined, the binary is installed in
+		/usr/games/hide, and a symbolic link is created to
+		/usr/games/dm.
+
+LDADD		Additional loader objects.  Usually used for libraries.
+		For example, to load with the compatibility and utility
+		libraries, use:
+
+			LDADD+=-lutil -lcompat
+
+LDFLAGS		Additional loader flags.
+
+LINKS		The list of binary links; should be full pathnames, the
+		linked-to file coming first, followed by the linked
+		file.  The files are hard-linked.  For example, to link
+		/bin/test and /bin/[, use:
+
+			LINKS=	${DESTDIR}/bin/test ${DESTDIR}/bin/[
+
+MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
+		defined, "MAN=${PROG}.1" is assumed.
+
+PROG		The name of the program to build.  If not supplied, nothing
+		is built.
+
+SRCS		List of source files to build the program.  If PROG is not
+		defined, it's assumed to be ${PROG}.c.
+
+DPADD		Additional dependencies for the program.  Usually used for
+		libraries.  For example, to depend on the compatibility and
+		utility libraries use:
+
+			DPADD+=${LIBCOMPAT} ${LIBUTIL}
+
+		The following libraries are predefined for DPADD:
+
+			LIBC		/lib/libc.a
+			LIBCOMPAT	/usr/lib/libcompat.a
+			LIBCRYPT	/usr/lib/libcrypt.a
+			LIBCURSES	/usr/lib/libcurses.a
+			LIBDBM		/usr/lib/libdbm.a
+			LIBDES		/usr/lib/libdes.a
+			LIBL		/usr/lib/libl.a
+			LIBKDB		/usr/lib/libkdb.a
+			LIBKRB		/usr/lib/libkrb.a
+			LIBKVM		/usr/lib/libkvm.a
+			LIBM		/usr/lib/libm.a
+			LIBMP		/usr/lib/libmp.a
+			LIBPC		/usr/lib/libpc.a
+			LIBPLOT		/usr/lib/libplot.a
+			LIBRPC		/usr/lib/sunrpc.a
+			LIBTERM		/usr/lib/libterm.a
+			LIBUTIL		/usr/lib/libutil.a
+
+SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
+		strings, using xstr(1). Note that this will not work with
+		parallel makes.
+
+STRIP		The flag passed to the install program to cause the binary
+		to be stripped.
+
+SUBDIR		A list of subdirectories that should be built as well.
+		Each of the targets will execute the same target in the
+		subdirectories.
+
+The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
+if it exists, as well as the include file <bsd.man.mk>.
+
+Some simple examples:
+
+To build foo from foo.c with a manual page foo.1, use:
+
+	PROG=	foo
+
+	.include <bsd.prog.mk>
+
+To build foo from foo.c with a manual page foo.2, add the line:
+
+	MAN=	foo.2
+
+If foo does not have a manual page at all, add the line:
+
+	NOMAN=	noman
+
+If foo has multiple source files, add the line:
+
+	SRCS=	a.c b.c c.c d.c
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.subdir.mk> contains the default targets for building
+subdirectories.  It has the same eight targets as <bsd.prog.mk>: all, 
+clean, cleandir, depend, includes, install, lint, and tags.  For all of
+the directories listed in the variable SUBDIRS, the specified directory 
+will be visited and the target made.  There is also a default target which
+allows the command "make subdir" where subdir is any directory listed in
+the variable SUBDIRS.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.sys.mk> is used by <bsd.prog.mk> and
+<bsd.lib.mk>.  It contains overrides that are used when building
+the NetBSD source tree.  For instance, if "PARALLEL" is defined by
+the program/library Makefile, it includes a set of rules for lex and
+yacc that allow multiple lex and yacc targets to be built in parallel.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+The include file <bsd.lib.mk> has support for building libraries.  It has
+the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
+includes, install, lint, and tags.  It has a limited number of suffixes,
+consistent with the current needs of the BSD tree.
+
+It sets/uses the following variables:
+
+LIB		The name of the library to build.
+
+LIBDIR		Target directory for libraries.
+
+LINTLIBDIR	Target directory for lint libraries.
+
+LIBGRP		Library group.
+
+LIBOWN		Library owner.
+
+LIBMODE		Library mode.
+
+LDADD		Additional loader objects.
+
+MAN		The manual pages to be installed (use a .1 - .9 suffix).
+
+SRCS		List of source files to build the library.  Suffix types
+		.s, .c, and .f are supported.  Note, .s files are preferred
+		to .c files of the same name.  (This is not the default for
+		versions of make.)
+
+The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
+if it exists, as well as the include file <bsd.man.mk>.
+
+It has rules for building profiled objects; profiled libraries are
+built by default.
+
+Libraries are ranlib'd when made.

+
+# Much of the complexity here is for supporting cross-building.
+# If a tree does not support that, simply using plain Makefile.depend
+# should provide sufficient clue.
+# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
+# as expected below.
+
+# Note: this file gets multiply included.
+# This is what we do with DIRDEPS
+
+# DIRDEPS:
+#	This is a list of directories - relative to SRCTOP, it is
+#	normally only of interest to .MAKE.LEVEL 0.
+#	In some cases the entry may be qualified with a .<machine>
+#	or .<target_spec> suffix (see TARGET_SPEC_VARS below),
+#	for example to force building something for the pseudo
+#	machines "host" or "common" regardless of current ${MACHINE}.
+#	
+#	All unqualified entries end up being qualified with .${TARGET_SPEC}
+#	and partially qualified (if TARGET_SPEC_VARS has multiple
+#	entries) are also expanded to a full .<target_spec>.
+#	The  _DIRDEP_USE target uses the suffix to set TARGET_SPEC
+#	correctly when visiting each entry.
+#
+#	The fully qualified directory entries are used to construct a
+#	dependency graph that will drive the build later.
+#	
+#	Also, for each fully qualified directory target, we will search
+#	using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
+#	dependencies.  We use Makefile.depend (default value for
+#	.MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
+#	distinguish them from others.
+#	
+#	Each Makefile.depend file sets DEP_RELDIR to be the
+#	the RELDIR (path relative to SRCTOP) for its directory, and
+#	since each Makefile.depend file includes dirdeps.mk, this
+#	processing is recursive and results in .MAKE.LEVEL 0 learning the
+#	dependencies of the tree wrt the initial directory (_DEP_RELDIR).
+#
+# BUILD_AT_LEVEL0
+#	Indicates whether .MAKE.LEVEL 0 builds anything:
+#	if "no" sub-makes are used to build everything,
+#	if "yes" sub-makes are only used to build for other machines.
+#	It is best to use "no", but this can require fixing some
+#	makefiles to not do anything at .MAKE.LEVEL 0.
+#
+# TARGET_SPEC_VARS
+#	The default value is just MACHINE, and for most environments
+#	this is sufficient.  The _DIRDEP_USE target actually sets
+#	both MACHINE and TARGET_SPEC to the suffix of the current
+#	target so that in the general case TARGET_SPEC can be ignored.
+#
+#	If more than MACHINE is needed then sys.mk needs to decompose
+#	TARGET_SPEC and set the relevant variables accordingly.

+# NAME:
+#	install-mk - install mk files
+#
+# SYNOPSIS:
+#	install-mk [options] [var=val] [dest]
+#
+# DESCRIPTION:
+#	This tool installs mk files in a semi-intelligent manner into
+#	"dest".
+#
+#	Options:
+#
+#	-n	just say what we want to do, but don't touch anything.
+#
+#	-f	use -f when copying sys,mk.
+#
+#	-v	be verbose
+#
+#	-q	be quiet
+#
+#	-m "mode"
+#		Use "mode" for installed files (444).
+#
+#	-o "owner"
+#		Use "owner" for installed files.
+#
+#	-g "group"
+#		Use "group" for installed files.
+#
+#	var=val
+#		Set "var" to "val".  See below.
+#
+#	All our *.mk files are copied to "dest" with appropriate
+#	ownership and permissions.
+#	
+#	By default if a sys.mk can be found in a standard location
+#	(that bmake will find) then no sys.mk will be put in "dest".
+#
+#	SKIP_SYS_MK:
+#		If set, we will avoid installing our 'sys.mk'
+#		This is probably a bad idea.
+#
+#	SKIP_BSD_MK:
+#		If set, we will skip making bsd.*.mk links to *.mk
+#
+#	sys.mk:
+#
+#	By default (and provided we are not installing to the system
+#	mk dir - '/usr/share/mk') we install our own 'sys.mk' which
+#	includes a sys specific file, or a generic one.

+# input looks like
+# MANIFEST= my.mtree
+# for each MANIFEST we have a list of dirs
+# ${MANIFEST}.DIRS += bin sbin usr/bin ...
+# for each dir we have a ${MANIFEST}.SRCS.$dir
+# that provides the absolute path to the contents
+# ${MANIFEST}.SRCS.bin += ${OBJTOP}/bin/sh/sh 
+# ${MANIFEST}.SYMLINKS is a list of src target pairs
+# for each file/dir there are a number of attributes
+# UID GID MODE FLAGS
+# which can be set per dir, per file or we use defaults
+# eg.  
+# MODE.sbin = 550
+# MODE.usr/sbin = 550
+# MODE.dirs = 555
+# means that sbin and usr/sbin get 550 all other dirs get 555
+# MODE.usr/bin/passwd = 4555
+# MODE.usr/bin.files = 555
+# MODE.usr/sbin.files = 500
+# means passwd gets 4555 other files in usr/bin get 555 and
+# files in usr/sbin get 500
+# STORE defaults to basename of src and target directory
+# but we can use 
+# ${MANIFEST}.SRCS.sbin += ${OBJTOP}/bin/sh-static/sh-static
+# STORE.sbin/sh-static = sbin/sh
