+2023-02-18  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* pdfmark.am (uninstall-pdfmark-hook): Simplify uninstallation.
+	Try to remove the configured `pdfdocdir` in the event it is
+	empty, but do not fail if it isn't.  (It can be a directory
+	shared with other groff components; we don't know in what order
+	the uninstall targets will serialize, but the last one run
+	should succeed.)
+
+2022-09-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* sanitize.tmac: Move comment to where escape sequences are
+	recognized.  Problem arose in commit 058b63ce3d, 2021-09-04.
+
+	troff:.../contrib/pdfmark/sanitize.tmac:162: warning: macro '\"'
+	not defined
+
+2022-05-20  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* pdfmark.am: Rename `BUILD_PDFDOC` to `USE_GROPDF`.
+
+2022-03-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* pdfmark.am: Eliminate `PDFMARK_TFLAG` and `PDFMARK_PFLAG` Make
+	macros; they were expanded in only one place.
+	(PDFROFF): Track rename of Make macro `TFLAG` to `MFLAG`.
+
+2022-03-30  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* cover.ms: Die horribly if `PSPIC` call fails.
+
+2022-03-26  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* pdfmark.am (PDFDOCFILES): Replace hard-coded "gnu.eps"
+	file name with expansion of `DOC_GNU_EPS`.
+	(contrib/pdfmark/pdfmark.pdf): Pass `-I` option to pdfroff(1) to
+	enable location of "gnu.eps" file.
+
+2021-10-24  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Adapt to accommodate global XH and XN implementations.
+
+	cf. <https://savannah.gnu.org/bugs/?58946#comment13>
+
+	* spdf.tmac (XH-INIT, XN-INIT, XH-UPDATE-TOC): Delete definitions;
+	the defaults, provided by s.tmac, are now sufficient.
+	(XH-REPLACEMENT, XN-REPLACEMENT): Define these, rather than...
+	(XH, XN): ...these, respectively.
+
+2021-10-02  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Make a minor layout adjustment.
+
+	* pdfmark.ms (Section 2.4.3): Add a vertical space reservation, to
+	avoid a widow line at the end of the paragraph explaining use of...
+	(PDFHREF.Y): ...this computed register, in the definition of...
+	(PDFBOOKMARK.VIEW): ...this.
+
+2021-10-02  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Clarify references to use of the -Tpdf option.
+
+	* pdfmark.ms (Section 2, Section 3.1): Add footnotes, indicating that
+	only "-Tps" and "-Tpdf" output formats are supported, and that "-Tpdf"
+	may avoid a separate step, to convert from PostScript to PDF.
+
+2021-10-02  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Work around misplacement of link "hot-spots" in footnotes.
+
+	* pdfmark.ms (pdfhref-nobreak): New document-local macro; used instead
+	of "pdfhref", this forces paragraph adjustment before placement of any
+	unbreakable link text, for which line-wrap may be required.  Currently
+	observed only within footnotes, without adjustment, the "hot-spot" for
+	the link may be placed 1v above its associated text.
+
+2021-10-02  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Link footnote reference marks to footnote text.
+
+	* pdfmark.ms (FP): Redefine locally; replace s.tmac default.
+	(FF): Do not redefine; our FP replacement macro does not use it.
+	[d FS-MARK] (FS-MARK): Redefine locally; map it to...
+	(pdf:fn.mark): ...this locally defined macro.
+	[!d FS-MARK] (@FS): Rename s.tmac implementation as...
+	(pdf:fn.record): ...this, then redefine @FS itself, to call...
+	(pdf:fn.mark, pdf:fn.record): ...these, in respective order.
+	(groff-1.19.1, GhostScript-8.14): Update footnote reference syntax.
+	(Ghostscript-8.14, MSYS): Emulate sentence space after footnote mark.
+	(*): Replace s.tmac string definition; make it equivalent to "\c",
+	after renaming its original implementation as...
+	(pdf:fn.index): ...this; synchronize references with changes to...
+	(pdf:fn.index.count): ...this new locally defined register; it is
+	auto-incremented by one, as each footnote is placed.
+
+2021-10-01  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Incorporate user-defined TOC leader style.
+
+	* pdfmark.ms: Make some comment tidy-up adjustments.
+	(TC-LEADER, TC-MARGIN): Define them, to take advantage of new
+	s.tmac features; cf. <https://savannah.gnu.org/bugs/?61157>.
+
+2021-09-18  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Factor a further unnecessary macro out of spdf.tmac
+
+	* spdf.tmac (XR): Remove it; relocate it to...
+	* pdfmark.ms (XR): ...here.
+
+2021-09-13  Keith Marshall  <keith.d.marshall@ntlworld.com>
+

+
+	* pdfmark.ms (EM): Annotate this locally-defined emphasis macro...
+	(CWB, CWI, CWBI): ...these constant width font interpolation macros...
+	(=): ...and this locally-defined IP tag variant string.
+
+2021-09-13  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Update defunct internet URL references.
+
+	* pdfmark.ms (pdfmark-manual): Adobe moved the document (again);
+	update the document reference macro, to follow the URL relocation.
+	(www.mingw.org): The MinGW Project has relinquished this domain;
+	update the URL reference, to follow web-site relocation to...
+	(mingw.osdn.io): ...here.
+
+2021-09-13  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Factor document-specific bloat out of spdf.tmac
+
+	* spdf.tmac: Reorganize; add many comments.
+	(XN): Retained, but reimplemented, to serve as...
+	(XH, XN): ...both of these; add callback hooks for...
+	(XH-INIT, XN-INIT, XH-UPDATE-TOC): ...these; provide no-op stubs;
+	factor out TOC collection code, delegating to XH-UPDATE-TOC.
+	(opt*XN-N, opt*XN-S, opt*XN-X): Rename internal macros to...
+	(de spdf:XH-N, de spdf:XH-S, de spdf:XH-X): ...these, respectively.
+	(AN, @AN, IE, IS, LU, NN, PXREF, SAME-PAGE, XM): Delete; we do not
+	require these; if users do, they should define their own.
+	(pdf@toc): Delete internal macro; fold body into...
+	(TC): ...this.
+
+	* pdfmark.ms (XH-UPDATE-TOC): Implement callback; it is based on...
+	(XN): ...original implementation of this, factored out of spdf.tmac,
+	but with significant simplification, to remove unnecessary code.
+	(XNVS1, XNVS2, XNVS3): Tighten vertical spacing.
+
+2021-09-04  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Reduce potential for user-space exposure of "ms" internals.
+
+	* spdf.tmac (@NH): Append to s.tmac macro; assign...
+	(spdf:nh*hl): ...this new internal register; alias it to...
+	(.NH): ...this new public name, hence making it track...
+	(nh*hl): ...this s.tmac internal numeric register.
+	(XN): Use \n[.NH] instead of \n[nh*hl].
+
+2021-09-03  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Sanitize text for use in PDF document outlines.
+
+	* sanitize.tmac: New file; it implements...
+	(sanitize): ...this new macro; interprets its first argument as a
+	string name, and copies its remaining arguments to the named string,
+	discarding specific embedded troff escape sequences; currently...
+	(\F): ...only this is identified as "specifically discardable".
+
+	* pdfmark.am (TMACFILES): Add sanitize.tmac
+
+	* spdf.tmac (mso): Include sanitize.tmac
+	(xn*ref, xn*argc): Rename all occurrences...
+	(spdf:refname, spdf:argc): ...to these, respectively.
+	(XN): Stop inserting $* directly into PDF outlines; instead, use...
+	(spdf:bm.text): ...this new string; this is locally defined by...
+	(spdf:bm.define): ...this new macro; passed the original $* from
+	XN, this itself, is locally defined as a redirectable alias for...
+	(spdf:bm.basic): ...this new local macro; it simply copies $*,
+	passed from XN, to the string named by its first argument, (which is
+	always spdf:bm.text), so reproducing previous behaviour.
+	(opt*XN-S): New macro; defined for internal use only, it adds a "-S"
+	option to XN, such that, when specified, it temporarily redirects...
+	(spdf:bm.define): ...this macro mapping alias to...
+	(sanitize): ...this.
+
+	* pdfmark.ms (XN): Add "-S" option for all headings which include...
+	(\F[C]...\F[]): ...this escape sequence.
+
+2021-08-21  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Define, and use registered trade mark strings.
+
+	* pdfmark.ms (Adobe, Acrobat, Distiller, PostScript, Microsoft):
+	Define as strings.  Each expands to its own name, followed by the
+	registered trademark symbol, as a superscript, and optional trailing
+	punctuation, below the superscript.  Use each as required.
+
+2021-08-21  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Prefer "-ize" to "-ise" where etymology permits.
+
+	* pdfmark.ms: For all verbs, and their derivative nouns, for which
+	British English allows either "-ise" or "-ize" as ending, prefer the
+	"-ize" form of verb, and "-ization" form of noun, throughout.
+
+2021-08-20  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Correct a spelling error.
+
+	* pdfmark.ms (Section 2.5.3.1): Fix typo: s/exanple/example/.
+
+2021-08-20  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Space out section headings in pdfmark.ms source.
+
+	* pdfmark.ms (.NH): Precede each instance by one null request, to
+	improve readability.
+
+2021-08-18  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Refine pdfroff "missing ghostscript" diagnostic.
+
+	* pdfroff.sh [$GS = ":"]: Fix typo: s/connot/cannot/; refine text.
+
+2020-12-25  G. Branden Robinson <g.branden.robinson@gmail.com>
+
+	* pdfmark.am (PDFROFF): Call pdfroff without
+	`--keep-temporary-files` option.  Temporary directories are
+	created with mktemp(1) and files with an embedded process
+	identifier, which frustrates reproducible builds.
+
+	See <https://savannah.gnu.org/bugs/?57218>.
+
+2018-02-28  Werner LEMBERG  <wl@gnu.org>
+
+	* pdfmark.am (pdfmark.pdf): Use $(GROFF_V).
+
+2018-02-28  Werner LEMBERG  <wl@gnu.org>
+
+	* pdfmark.am (pdfroff): Use $(AM_V_GEN) to silence file generation.
+
+2015-08-22  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* pdfroff.1.man: Rename `pdfroff.man'.
+
+	* pdfmark.am: Add `Last update'.  Setup Emacs mode.
+
+2015-08-05  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* pdfmark.am: Add `Last update'.  Setup Emacs mode.
+
+2015-04-03  Werner LEMBERG  <wl@gnu.org>
+
+	* pdfroff.man: Make it work in compatibility mode.
+
+2014-10-14  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Deduce "--no-toc-relocation" from input stream (revisited).
+
+	* pdfroff.sh (WRKFILE): Correct malformed sed expression.
+
+	* spdf.tmac (TC): Prefer value of pdfroff's PHASE register to defined
+	state of pdf:href.map, when choosing to emit control record to...
+	(toc_relocation): ...enable this.
+
+2014-10-13  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Deduce "--no-toc-relocation" from input stream.
+
+	* pdfroff.sh (WRKFILE): Scan it for "pdfroff-option:set" records;
+	apply settings; check for equivalent of "--no-toc-relocation" option.
+
+	* spdf.tmac (TC): Emit "pdfroff-option:set toc-relocation=enabled".
+
+2014-10-12  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Avoid spurious user visible control messages on stderr.
+
+	* pdfroff.sh (REFCOPY): Ensure that at least one pdfhref mark of type
+	'Z' will remain in the reference map, after all references have been
+	resolved; this is required, to suppress writing of reference control
+	records to stderr during the final PDF output processing phase.
+
+2014-09-04  Bernd Warken  <groff-bernd.warken-72@web.de>
+
+	* all pdfmark source files: Copying (remove last updates and
+	replace years with package years) and Emacs setup.
+
+2014-03-30  Steffen Nurpmeso  <sdaoden@yandex.com>
+
+	* Makefile.sub: Put straight error-prevention prefixes for `rm'.
+
+2014-03-29  Steffen Nurpmeso  <sdaoden@yandex.com>
+
+	* Makefile.sub: Handle examples separately, controlled by
+	$(make{_,_install_,_uninstall_}examples).
+
+2013-01-28  Deri James  <deri@chuzzlewit.myzen.co.uk>
+
+	* pdfmark.tmac (pdfmark, pdf:composed): Use `\!' instead of `\X'.
+
+	With the old pdfmark there are gaps between two of the lines, but
+	with the new version they disappear.  The use of `.br' and `.in 0'
+	is arbitrary any request which causes an implicit break could be
+	used.  Two breaks together only produce one line break, but if there
+	is an intervening `\X' then the second break finds the line buffer
+	not empty and generates another line break.
+
+	Using `\!' does alter the position of the pdfmark lines in the
+	intermediate file sent to grops (the pdfmark lines are output
+	immediately rather than being serialised through the output line
+	processing), but this has no effect since the contents of the
+	pdfmark line stay the same.  It is the contents which determine
+	where bookmarks jump to not the position of the record in the input
+	stream to grops.
+
+	I initially used `.output', but hit a snag if a pdfbookmark occurs
+	before the document starts to output (message saying to insert an
+	explicit `.br'), this is quite likely for things like `.pdfinfo
+	/Author' which occur at the top of the document.  So I'm using the
+	`\!' escape.
+
+2012-09-20  Werner LEMBERG  <wl@gnu.org>
+
+	Simplify enviroment handling.
+
+	Suggested by Ivan Shmakov <oneingray@gmail.com>.
+
+	* Makefile.sub (PDFROFF): Don't use export.
+
+2011-12-26  Mike Frysinger  <vapier@gentoo.org>
+
+	Fix parallel build race failure.
+
+	Sometimes building in parallel will fail in the pdfmark directory:
+
+	  make[2]: Entering directory '.../contrib/pdfmark'
+	  rm -f pdfroff
+	  rm -f pdfmark.pdf
+	  sed -f ... ./pdfroff.sh >pdfroff
+	  ...; ./pdfroff ... pdfmark.ms >pdfmark.pdf
+	  /bin/sh: ./pdfroff: Permission denied
+	  chmod +x pdfroff
+	  make[2]: *** [pdfmark.pdf] Error 126
+
+	This is because the generated pdf files use the local generated
+	pdfroff helper script, but they don't depend directly upon it, so
+	make tries to create the two in parallel and randomly falls over.
+
+	* Makefile.sub: Have all the .pdf files explicitly depend on the
+	`pdfroff' helper script.
+
+2010-12-23  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Update copyright notices; pdfmark.tmac bug-fix.
+
+	* pdfmark.tmac: Update copyright notices.
+	(pdf*href.mark.resolve): Avoid premature removal, by aliasing to...
+	(pdf*href.mark.begin): ...this, rather than renaming.
+
+	* pdfroff.sh, pdfroff.man: Update copyright notices.
+
+2010-12-14  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Clean up handling of temporary files directory.
+
+	* .cvsignore (pdfroff-*): Ignore sub-directories matching this.
+	* Makefile.sub (MOSTLCLEANDIRADD): Schedule them for removal.
+
+2010-12-02  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Address potential temporary file security vulnerabilities.
+
+	* pdfroff.sh (GROFF_TMPDIR): Use mktemp(1) to assign it, if possible;
+	fall back to ${TMPDIR}, ${TMP} or ${TEMP} if unsuccessful.
+	* pdfroff.man: Document it.
+
+2009-08-16  Colin Watson  <cjwatson@debian.org>
+
+	Make pdfroff's GhostScript invocation safer.
+
+	* pdfroff.sh (PDFROFF_POSTPROCESSOR_COMMAND): Add `-dSAFER' option.
+	* pdfroff.man: Document it.
+
+2008-12-28  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Avoid phantom line wrapping in pdfhref hot-spots.
+
+	* pdfmark.tmac (pdf*href.mark.end): Emit hot-spot end markers within
+	scope of `\Z', to prevent possible output line length overflow which
+	may occur only in the layout computation passes, but not in the final
+	output pass.  Problem observed and identified by Nick Stoughton; it
+	causes some hot-spots to be displaced from their proper locations.
+
+2007-04-11  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	Avoid stray newlines in folded pdfmark literal content.
+
+	* pdfmark.tmac (pdf*pdfmark.dispatch.wrapped): New string; define it
+	when accumulating long literal content; make it undefined otherwise.
+	(PDFMARK.FOLDWIDTH, PDFMARK.FOLDWIDTH.MAX): Reserve space for two
+	extra characters, to accommodate a space and an escaped newline,
+	while accumulating literal content, in case folding is required.
+	(pdf*pdfmark.dispatch) [pdf*pdfmark.dispatch.wrapped]: Add them.
+
+2007-04-11  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	* pdfmark.tmac (pdfbookmark): Don't evaluate within diversions; defer
+	placement until diversion is copied out at top level.
+
+2007-02-06  Eric S. Raymond  <esr@snark.thyrsus.com>
+
+	* pdfroff.man: Update .UR/.UE and .MT/.ME to latest changes in
+	an-ext.tmac.
+
+2007-01-30  Werner LEMBERG  <wl@gnu.org>
+
+	* pdfroff.man: Updated.
+
+2007-01-21  Werner LEMBERG  <wl@gnu.org>
+
+	* pdfroff.man: Revised, based on a patch from Eric Raymond.  It now
+	uses the new macros from an-ext.tmac.  This is the first of a series
+	of man patches which Eric has contributed.
+
+2006-07-30  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	* pdfroff.sh (PDFROFF_KILL_NULL_PAGES): Require `%%BeginPageSetup' on
+	PostScript output line immediately following `%%Page:'.

+
+	* pdfroff.sh (PDFROFF_KILL_NULL_PAGES): Require `sed' to match a more
+	explicit regular expression, for detection of redundant pages.
+
+2006-07-14  Keith Marshall  <keith.d.marshall@ntlworld.com>
+
+	* pdfroff.sh (PDFWRITE): Local shell variable replaced...
+	(PDFROFF_POSTPROCESSOR_COMMAND): by this new  environment variable...
+	(GROFF_GHOSTSCRIPT_INTERPRETER): with this bound to it.
+	(PDFROFF_COLLATE, PDFROFF_KILL_NULL_PAGES): New environment variables.
+	(--no-kill-null-pages): New command line option; implement it, and...
+	(--help): Add description for it.
+
+	* pdfroff.man (PDFROFF_POSTPROCESSOR_COMMAND): Document it.
+	(PDFROFF_COLLATE, PDFROFF_KILL_NULL_PAGES): Document them.
+	(--no-kill-null-pages): Document it.
+
+2006-07-14  Zvezdan Petkovic  <zpetkovic@acm.org>
+
+	* pdfroff.sh (--emit-ps): New command line option; implement it.
+	(--help): Add description for it.
+

+
+	* pdfroff.man: Add `.ig' block after NAME section to make mandb
+	happy.

+	detect parenthesised literals in pdfmark content, so folding can be
+	avoided within them, subject to honouring of `PDFMARK.FOLDWIDTH'.
+	(pdf*length.increment): New macro; it triggers output folding when ...
+	(pdf:length): ... this new register exceeds `PDFMARK.FOLDWIDTH.MAX'.
+	(pdf*pdfmark.post.first, pdf*pdfmark.post.next): New macros; each will
+	be aliased as required to ...
+	(pdf*pdfmark.post): ... this, and invoked by ...

+	(pdf*end): ... this new macro to terminate it.
+
