+
+ * gpinyin.pl: Report groff version number along with this
+ program's own when not run from source tree. Drop dead code.
+ Bump micro version number to reflect recent restructuring.
+
+2022-10-09 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ Make gpinyin script stand alone.
+
+ * subs.pl: Delete, moving its content into...
+ * gpinyin.pl: ...here.
+ (vowel_t): Use explicit list with `my`.
+ (vowel_n, vowel_t): Declare local scalar `$vowel_with_tone`
+ using `my`.
+ * gpinyin.am (dist_gpinyin_DATA): Delete.
+
+2022-05-03 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * gpinyin.am (gpinyin): Fix missing dependency on
+ `$(SH_DEPS_SED_SCRIPT)`.
+
+2021-05-11 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * gpinyin.1.man: Render the tone mark table only if the output
+ device might be capable.
+
+ Fixes <https://savannah.gnu.org/bugs/index.php?55215>.
+
+2021-05-10 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * gpinyin.1.man: Work around inability of grops and gropdf to
+ construct some Unicode composite characters. Use groff
+ composite special characters for "a" with acute and grave
+ accents, and define strings for "a" with macron (overline) and
+ with háček/caron accents. Use different string definitions for
+ nroff and troff modes so we don't regress UTF-8 terminal output.
+
+2021-05-10 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * subs.pl (vowel_t): Fix incorrect rendering of base glyph 'U',
+ which was being forced to lowercase when a dieresis and tone
+ mark were both being applied. This caused the tone mark to
+ overlap the dieresis, so decrease the font size of the base
+ glyph even more to compensate. The result is ugly but
+ comprehensible.
+
+ See <https://savannah.gnu.org/bugs/?57524>, partially mitigated
+ but not completely resolved.
+
+2021-05-09 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * subs.pl (%tones1_Unicode): Fix copy and paste error. Emit
+ U+01D5 (Latin capital letter u with dieresis and macron) for Ü
+ with tone 1, instead of U+016A (Latin capital letter u with
+ macron).
+
+ Fixes <https://savannah.gnu.org/bugs/?60562>.
+
+2021-05-09 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * subs.pl (handle_word): Emit \[cq] instead of \[aq] when
+ interpolating an apostrophe before a vowel.
+
+ Fixes <https://savannah.gnu.org/bugs/?60561>.
+
+2021-05-09 G. Branden Robinson <g.branden.robinson@gmail.com>
+
+ * subs.pl (%tones_glyphs, %tones4_glyphs): Fix hash keys to use
+ the groff dotless i special character into which a lowercase "i"
+ has already been transformed instead of 'i' itself.
+ (vowel_n, vowel_t): Rename variable so that tone-transformed
+ vowel is stored separately. Add "or warn" to test the result
+ and cheaply assert that we got a string back from our hash
+ lookup on the vowel.
+
+ Fixes <https://savannah.gnu.org/bugs/?60560>.
+
+2021-01-06 Colin Watson <cjwatson@debian.org>
+
+ * gpinyin.pl: Avoid Perl's unsafe "<>" operator.
+
+ The "<>" operator is implemented using the two-argument form of
+ "open", which interprets magic such as pipe characters, allowing
+ execution of arbitrary commands which is unlikely to be
+ expected. Perl >= 5.22 has a "<<>>" operator which avoids this,
+ but also forbids the use of "-" to mean the standard input,
+ which is a facility that the affected groff programs document.
+
+ ARGV::readonly would probably also fix this, but I fundamentally
+ dislike the approach of escaping data in preparation for a
+ language facility to unescape it, especially when the required
+ escaping is as non-obvious as it is here. (For the same reason,
+ I prefer to use subprocess invocation facilities that allow
+ passing the argument list as a list rather than as a string to
+ be interpreted by the shell.) So I've abandoned this dubious
+ convenience and changed the affected programs to iterate over
+ command-line arguments manually using the three-argument form of
+ open.
+
+ Fixes <https://savannah.gnu.org/bugs/?55557>.

+.
+.I gpinyin
+is a preprocessor for
+.MR groff @MAN1EXT@
+that facilitates use of Hanyu Pinyin in
+.MR groff @MAN7EXT@
+files.
+.
+Pinyin is a method for writing the Mandarin Chinese language with the
+Latin alphabet.
+.
+Mandarin consists of more than four hundred base syllables,
+each spoken with one of five different tones.
+.
+Changing the tone applied to the syllable generally alters the meaning
+of the word it forms.
+.
+In Pinyin,
+a syllable is written in the Latin alphabet and a numeric tone indicator
+can be appended to each syllable.
+.
+.
+.P
+Each
+.I input-file
+is a file name or the character
+.RB \[lq] \- \[rq]
+to indicate that the standard input stream should be read.
+.
+As usual,
+the argument
+.RB \[lq] \-\- \[rq]
+can be used in order to force interpretation of all remaining arguments
+as file names,
+even if an
+.I input-file
+argument begins with a
+.RB \[lq] \- \[rq].
+.
+.B \-h
+and
+.B \-\-help
+display a usage message,

+.B \-v

+.
+.\" ====================================================================
+.SS "Pinyin sections"
+.\" ====================================================================
+.
+Pinyin sections in
+.I groff
+files are enclosed by two
+.B .pinyin
+requests with different arguments.
+.
+The starting request is
+.RS
+.EX
+\&.pinyin start
+.EE
+.RE
+or
+.RS
+.EX
+\&.pinyin begin
+.EE
+.RE
+and the ending request is
+.RS
+.EX
+\&.pinyin stop
+.EE
+.RE
+or
+.RS
+.EX
+\&.pinyin end
+.EE
+.RE
+\&.
+.
+.
+.\" ====================================================================
+.SS Syllables
+.\" ====================================================================
+.
+In Pinyin,
+each syllable is represented by one to six letters drawn from the
+fifty-two upper- and lowercase letters of the Unicode basic Latin
+character set,
+plus the letter \[lq]U\[rq] with dieresis (umlaut) in both cases\[em]in
+other words,
+the members of the set \[lq][a\[en]zA\[en]Z\[:u]\[:U]]\[rq].
+.
+.
+.P
+In
+.I groff
+input,
+all basic Latin letters are written as themselves.
+.
+The \[lq]u with dieresis\[rq] can be written as
+\[lq]\e[:u]\[rq]
+in lowercase or
+\[lq]\e[:U]\[rq]
+in uppercase.
+.
+Within
+.B .pinyin
+sections,
+.I gpinyin
+supports the form
+\[lq]ue\[rq]
+for lowercase and the forms
+\[lq]Ue\[rq]
+and
+\[lq]UE\[rq]
+for uppercase.
+.
+.
+.\" ====================================================================
+.SS Tones
+.\" ====================================================================
+.
+Each syllable has exactly one of five
+.IR tones .
+.
+The fifth tone is not explicitly written at all,
+but each of the first through fourth tones is indicated with a diacritic
+above a specific vowel within the syllable.
+.
+.
+.P
+In a
+.I gpinyin
+source file,
+these tones are written by adding a numeral in the range 0 to 5 after
+the syllable.
+.
+The tone numbers 1 to 4 are transformed into accents above vowels in the
+output.
+.
+The tone numbers 0 and 5 are synonymous.
