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>

	* install-mk (MK_VERSION): bump version to 20121111
	* autoconf.mk: avoid meta mode seeing changed commands for config.status
	* 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>

	* install-mk (MK_VERSION): bump version to 20121106

2012-11-05  Simon J. Gerraty  <sjg@bad.crufty.net>

	* import latest dirdeps.mk and meta2deps.py from Juniper.
	* progs.mk: add MAN and CXXFLAGS to PROG_VARS
	  also add PROGS_TARGETS and pass on PROG_CXX if it seems
	  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.
	* progs.mk: Add LDADD to PROG_VARS
	
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
	* meta.stage.mk (STAGE_DIRDEP_SCRIPT): check that an existing
	target.dirdep matches .dirdep

2012-08-08  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): bump version to 20120808
	* import latest meta2deps.py from Juniper.

2012-07-11  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): bump version to 20120711
	* dep.mk: add explicit dependencies on SRCS after applying
	  SRCS_DEP_FILTER 
	* meta.autodep.mk: add explicit dependencies on SRCS after
	  applying SRCS_DEP_FILTER
	* meta.autodep.mk: ensure GENDIRDEPS_FILTER is exported if needed.
	
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>

	* install-mk (MK_VERSION): bump version to 20111028
	* sys.mk: include auto.obj.mk if MKOBJDIRS is set to auto
	* subdir.mk: ensure _SUBDIRUSE is provided
	* meta.autodep.mk: remove dependency of gendirdeps.mk on auto.obj.mk 
	* meta.subdir.mk: always allow for Makefile.depend
	
2011-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): bump version to 20111010
	  o minor tweak to *dirdeps.mk from Juniper sjg@
	
2011-10-01  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): bump version to 20111001
	  o add meta2deps.py from Juniper sjg@
	  o tweak gendirdeps.mk to work with meta2deps.py when not
	    cross-building 
	* 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

	  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
	* meta.autodep.mk: improve bootstraping

2011-06-10  Simon J. Gerraty  <sjg@bad.crufty.net>

	* yacc.mk: handle the corner case of .c being removed
	  while .h remains.

2011-06-08  Simon J. Gerraty  <sjg@bad.crufty.net>

	* yacc.mk: do .y.h and .y.c separately

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
	  first release including meta mode makefiles

2011-05-02  Simon J. Gerraty  <sjg@bad.crufty.net>

	  for things that need to be staged with different names.

2011-05-01  Simon J. Gerraty  <sjg@bad.crufty.net>

	* rst2htm.mk: convert rst to s5 (slides) or plain html depending
	  on target name.

	* install-mk (MK_VERSION): bump version to 20110330

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
	* meta.subdir.mk: add support for -DBOOTSTRAP_DEPENDFILES

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.
	we do this as meta.sys.mk, meta.autodep.mk and meta.subdir.mk
	to make turning it on/off simple.

	* 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.

	  do not install examples/*
	* FILES: add examples/sys.clean-env.mk

	  this requires bmake-20100606 or later to work.

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>

	* sys.mk: canonicalize MAKE_VERSION
	  old versions reported bmake-<src-date> build-<build-date>
	  whereas we only care about <src-date>

2010-04-25  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk: just warn about FORCE_{BSD,SYS}_MK being ignored

	  asked to do that.
	  fix/simplify the tests for when to run mkdep.
	* auto.dep.mk: add some explaination 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.

	* sys/Darwin.mk: Use .dylib for DSHLIBEXT and HOST_LIBEXT
	* sys/SunOS.mk: we need to export PATH

2009-12-23  Simon J. Gerraty  <sjg@void.crufty.net>

	* install-mk (MK_VERSION): bump version
	  include rst2htm.mk

2009-12-17  Simon J. Gerraty  <sjg@void.crufty.net>

2003-08-07  Simon J. Gerraty  <sjg@void.crufty.net>

	* install-mk: if FORCE_BSD_MK={cp,ln} use the ones in SYS_MK_DIR
	not the portable ones.

2003-07-31  Simon J. Gerraty  <sjg@void.crufty.net>

	* install-mk: add ability to use cp -f when updating
