+
+# 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.
+#	It is important that MACHINE be included in and actually be
+#	the first member of TARGET_SPEC_VARS.  This allows other
+#	variables to be considered optional, and some of the treatment
+#	below relies on MACHINE being the first entry.
+#	Note: TARGET_SPEC cannot contain any '.'s so the target
+#	triple used by compiler folk won't work (directly anyway).
+#
+#	For example:
+#
+#		# Always list MACHINE first, 
+#		# other variables might be optional.
+#		TARGET_SPEC_VARS = MACHINE TARGET_OS
+#		.if ${TARGET_SPEC:Uno:M*,*} != ""
+#		_tspec := ${TARGET_SPEC:S/,/ /g}
+#		MACHINE := ${_tspec:[1]}

+#		# and deal with MACHINE=${TARGET_SPEC} in the environment.

+*much* more efficient.
+
+The parsing work is handled by the class MetaFile.
+We only pay attention to a subset of the information in the
+"meta" files.  Specifically:
+
+'CWD'	to initialize our notion.
+
+'C'	to track chdir(2) on a per process basis
+
+'R'	files read are what we really care about.
+	directories read, provide a clue to resolving
+	subsequent relative paths.  That is if we cannot find
+	them relative to 'cwd', we check relative to the last
+	dir read.
+
+'W'	files opened for write or read-write,
+	for filemon V3 and earlier.
+        
+'E'	files executed.
+
+'L'	files linked
+
+'V'	the filemon version, this record is used as a clue
+	that we have reached the interesting bit.

+
+# NAME:
+#	meta2deps.sh - extract useful info from .meta files
+#
+# SYNOPSIS:
+#	meta2deps.sh SB="SB" "meta" ...
+#	
+# DESCRIPTION:
+#	This script looks each "meta" file and extracts the
+#	information needed to deduce build and src dependencies.
+#	
+#	To do this, we extract the 'CWD' record as well as all the
+#	syscall traces which describe 'R'ead, 'C'hdir and 'E'xec
+#	syscalls.
+#
+#	The typical meta file looks like::
+#.nf
+#
+#	# Meta data file "path"
+#	CMD "command-line"
+#	CWD "cwd"
+#	TARGET "target"
+#	-- command output --
+#	-- filemon acquired metadata --
+#	# buildmon version 2
+#	V 2
+#	E "pid" "path"
+#	R "pid" "path"
+#	C "pid" "cwd"
+#	R "pid" "path"
+#	X "pid" "status"
+#.fi
+#
+#	The fact that all the syscall entry lines start with a single
+#	character make these files quite easy to process using sed(1).
+#
+#	To simplify the logic the 'CWD' line is made to look like a
+#	normal 'C'hdir entry, and "cwd" is remembered so that it can
+#	be prefixed to any "path" which is not absolute.
+#
+#	If the "path" being read ends in '.srcrel' it is the content
+#	of (actually the first line of) that file that we are
+#	interested in.
+#
+#	Any "path" which lies outside of the sandbox "SB" is generally
+#	not of interest and is ignored.
+#
+#	The output, is a set of absolute paths with "SB" like:
+#.nf
+#
+#	$SB/obj-i386/bsd/gnu/lib/csu
+#	$SB/obj-i386/bsd/gnu/lib/libgcc
+#	$SB/obj-i386/bsd/include
+#	$SB/obj-i386/bsd/lib/csu/i386-elf
+#	$SB/obj-i386/bsd/lib/libc
+#	$SB/src/bsd/include
+#	$SB/src/bsd/sys/i386/include
+#	$SB/src/bsd/sys/sys
+#	$SB/src/pan-release/rtsock
+#	$SB/src/pfe-shared/include/jnx
+#.fi
+#
+#	Which can then be further processed by 'gendirdeps.mk'
+#
+#	If we are passed 'DPDEPS='"dpdeps", then for each src file
+#	outside of "CURDIR" we read, we output a line like:
+#.nf
+#
+#	DPDEPS_$path += $RELDIR
+#.fi
+#
+#	with "$path" geting turned into reldir's, so that we can end
+#	up with a list of all the directories which depend on each src
+#	file in another directory.  This can allow for efficient yet
+#	complete testing of changes.

+
+# NAME:
+#	stage-install.sh - wrapper around install
+#
+# SYNOPSIS:
+#	stage-install.sh [variable="value"] "args" "dest"
+#
+# DESCRIPTION:
+#	This script is a wrapper around the normal install(1).
+#	Its role is to add '.dirdep' files to the destination.
+#	The variables we might use are:
+#
+#	INSTALL
+#		Path to actual install(1), default is
+#		$REAL_INSTALL
+#
+#	OBJDIR
+#		Path to the dir where '.dirdep' was generated,
+#		default is '.'
+#
+#	_DIRDEP
+#		Path to actual '.dirdep' file, default is
+#		$OBJDIR/.dirdep
+#
+#	The "args" and "dest" are passed as is to install(1), and if a
+#	'.dirdep' file exists it will be linked or copied to each
+#	"file".dirdep placed in "dest" or "dest".dirdep if it happed
+#	to be a file rather than a directory.
