+# TypoG – Typographic Fine-Tuning for LaTeX
+
+LaTeX package `typog` provides macros for (micro-)typographic enhancements;
+it covers a variety of topics:
+
+* Precise hyphenation control
+* Disable/break ligatures
+* Manual italic correction
+* Extra kerning for slash and hyphen
+* Raising selected characters (e.g. hyphen, en-dash, and em-dash)
+* Aligning of the last line of a paragraph
+* Filling of the last line last line of a paragraph
+* Word spacing control
+* [Microtype](https://github.com/schlcht/microtype) front-end
+* Slightly sloppy paragraphs
+* Vertically partially-tied paragraphs
+* Breakable displayed equations
+* Setspace front-end
+* Smooth ragged-right paragraphs
+
+Moreover `typog` provides an environment to flag interesting parts of
+the information deluge typically accumulating in a LaTeX *log*-file
+and an associated tool, **typog-grep**, that selectively retrieves
+these parts.
+
+
+## Installation
+
+The minimally necessary files to install typog are *typog.ins* and *typog.dtx*. Running LaTeX
+on *typog.ins* in particular produces *typog.sty*:
+
+ latex typog.ins
+
+After extraction from *typog.dtx* place *typog.sty* in a directory mentioned in your TEXINPUTS
+paths or copy it into one of the directories for your LaTeX installation's *sty*-files and run
+**mktexlsr** or equivalent.
+
+To build the documentation it is easier to use the GNU *Makefile*:
+
+ make
+
+To construct the manual *typog.pdf* or the usage example *typog-example.pdf* a working
+[MetaPost](https://tug.org/metapost.html) installation and some
+[POD](https://perldoc.perl.org/perlpod) utilities of a [Perl](https://www.perl.org/)
+distribution are required. Cautious users can run
+
+ make tool-check
+
+ahead to verify that the required utilities are installed and working.
+For an overview over the most important *Makefile* targets use
+
+ make help
+
+
+## Usage
+
+Load the package with the usual incantation
+
+ \usepackage{typog}
+
+See Section 2 of the package documentation for available options.
+
+
+## Documentation
+
+The package documentation can be found
+[online](https://cspiel.github.io/typog/).

+# How to prepare a new release
+
+... and not make too many mistakes.
+
+
+1. Check that the work-area is clean with respect to **git**-tracked
+ files.
+
+ ``` git status ```
+
+1. Update the date stamp of `\ProvidesPackage`.
+
+1. (Temporarily) Zero the `\overfullrule`s of the documentation and
+ the example files.
+
+1. Thoroughly clean the work-area:
+
+ ```make maintainer-clean```
+
+1. Rebuild:
+
+ ```make```
+
+1. Check that all _*.sty_ and _*.pdf_ files are in good shape.
+
+1. Push the documentation files created in the previous step down into
+ the *docs* directory:
+
+ ```make update-docs```
+
+1. Undo the `\overfullrule` change.
+
+1. Commit the changes:
+
+ ```
+ git add .
+ ```
+
+ and finally
+
+ ```
+ git commit
+ ```
+
+1. Tag the commit with the version string of `\ProvidesPackage`:
+
+ ```git tag v1.23```
+
+1. Push the changes to the public repository:
+
+ ```git push origin master --tags```

+\subsection{Last Line Ragged Left/Flush Right}
+
+\Cref{ex:lastlineraggedleftpar} is a typical use of environment~\code{lastlineraggedleftpar}:
+A narrow paragraph gets typeset with full justification
+and put \code{\string\flushright} against the right margin as a whole.
+
+The layout may look more coherent if the last lines is moved to the right margin, too.
+

+\subsection{Last Line Centered}
+
+The situation shown in \cref{ex:lastlinecenteredpar} is
+more widespread than \cref{ex:lastlineraggedleftpar}
+because centered tables and figures are quite common.
+Their caption parboxes are centered too,
+which is where a centered last line might fortify the layout.
+
+Another possible use of environment~\code{lastlinecenteredpar} are the final lines of chapters~--
+in particular if the chapters' ends are marked with centered dingbats.
+
+\begin{exemplary}
+ \centering
+ \caption[Typeset a justified paragraph that is centered.]
+ {\lastlinecenteredpar
+ Typeset a justified paragraph that is centered.

+=head1 NAME
+
+typog-grep - grep for typog-inspect elements in LaTeX log files
+
+=head1 SYNOPSIS
+
+=over
+
+=item B<typog-grep> -a|--all|--any [I<OPTION>...] F<LOG-FILE>...
+
+=item B<typog-grep> [I<OPTION>...] I<REGEXP> F<LOG-FILE>...
+
+=back
+
+The first form shows all C<E<lt>typog-inspect id="I<ID>" ...E<gt>> elements in F<LOG-FILE>.
+
+The second form shows the contents of C<E<lt>typog-inspect id="I<ID>" ...E<gt>> elements
+whose I<ID>s match I<REGEXP> in F<LOG-FILE>.
+
+If no F<LOG-FILE> is given read from F<stdin>.
+The S<filename C<->> is synonymous to F<stdin>.
+
+=head1 DESCRIPTION
+
+B<typog-grep> is a tailored post-processor for LaTeX log files
+and the C<typoginspect> environment as provided by S<package typog>.
+It shares more with the venerable
+L<B<sgrep>|https://www.cs.helsinki.fi/u/jjaakkol/sgrep.html>
+than with S<POSIX L<B<grep>|https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html>>.
+
+The LaTeX user brackets her text in
+
+ \begin{typoginspect}{ID}
+ Text and code to investigate
+ \end{typoginspect}
+
+where I<ID> is used to identify one or more bracketed snippets.
+I<ID> does not have to be unique.
+The I<REGEXP> mechanism makes it easy to select groups of related I<ID>s
+if they are named accordingly.
+
+In F<LOG-FILE> the environment shows up, packed with tracing information, as
+
+=begin texinfo
+
+ at display
+ at relax
+
+=end texinfo
+
+ <typog-inspect id="ID" job="JOB-NAME" line="LINE-NUMBER" page="PAGE-NUMBER">
+ Trace Data
+ </typog-inspect>
+
+=begin texinfo
+
+ at end display
+ at relax
+
+=end texinfo
+
+where all the capital-letter sequences are meta-variables
+and in particular
+I<JOB-NAME> is the expansion of C<\jobname>,
+I<LINE-NUMBER> is the LaTeX source file line number
+of the beginning of the C<typoginspect> environment,
+and I<PAGE-NUMBER> is the page where
+the output of S<C<Text and code to investigate>> occurs.
+
+B<typog-grep> reveals the contents of F<LOG-FILE>
+between C<E<lt>typog-inspect id="I<ID>" ...E<gt>>
+and C<E<lt>/typog-inspectE<gt>> excluding the XML-tags.
+Access the I<JOB-NAME>, I<LINE-NUMBER>, and I<PAGE-NUMBER>
+with the commandline options
+B<--job-name>, B<--line-number>, and B<--page-number>, respectively.
+Use B<--id> to show the name of the IDs that matched I<REGEXP>.
+
+C<typoginspect> environments can be nested.
+B<typog-grep> respects the nesting,
+i.e., if the I<ID> of the nested environment does not match I<REGEXP>
+it will not be included in the program's output.
+
+=head1 OPTIONS
+
+The list of options is sorted by the names of the long options.
+
+=over 4
+
+=item B<-a>, B<--all>, B<--any>

+Print the actual id name that matched I<REGEXP>.
+Control the appearance of the matching id with configuration S<item C<id-heading>>.
+
+=item B<-y>, B<--[no-]ignore-case>
+
+Match ids while ignoring case distinctions in patterns and data.
+
+=item B<-j>, B<--[no-]job-name>
+
+Print the C<\jobname> that B<tex> associated with the input file.
+
+=item B<-n>, B<--[no-]line-number>
+
+Print the line number where the S<C<typoginspect> environment>
+was encountered in the LaTeX source file.
+
+=item B<-N>, B<--[no-]log-line-number>
+
+Print the line number of the F<log>-file where the current line was encountered.
+
+=item B<-p>, B<--[no-]page-number>
+
+Print page number where the contents of the S<C<typoginspect> environment>
+starts in the typeset document.
+
+=item B<-P>, B<--[no-]pager>
+
+Redirect output from F<stdout> to the configured pager.
+
+=item B<--show-config>
+
+Show the default configuration and exit.
+
+=item B<-V>, B<--version>

+.IX Header "DESCRIPTION"
+\&\fBtypog-grep\fR is a tailored post-processor for LaTeX log files
+and the \f(CW\*(C`typoginspect\*(C'\fR environment as provided by package\ typog.
+It shares more with the venerable
+\&\fBsgrep\fR <https://www.cs.helsinki.fi/u/jjaakkol/sgrep.html>
+than with \s-1POSIX\s0\ \fBgrep\fR <https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html>.
+.PP
+The LaTeX user brackets her text in
+.PP
+.Vb 3
+\& \ebegin{typoginspect}{ID}
+\& Text and code to investigate
+\& \eend{typoginspect}
+.Ve
+.PP
+where \fI\s-1ID\s0\fR is used to identify one or more bracketed snippets.
+\&\fI\s-1ID\s0\fR does not have to be unique.
+The \fI\s-1REGEXP\s0\fR mechanism makes it easy to select groups of related \fI\s-1ID\s0\fRs
+if they are named accordingly.
+.PP
+In \fILOG-FILE\fR the environment shows up, packed with tracing information, as
+.PP
+.Vb 3
+\& <typog\-inspect id="ID" job="JOB\-NAME" line="LINE\-NUMBER" page="PAGE\-NUMBER">
+\& Trace Data
+\& </typog\-inspect>
+.Ve
+.PP
+where all the capital-letter sequences are meta-variables
+and in particular
+\&\fIJOB-NAME\fR is the expansion of \f(CW\*(C`\ejobname\*(C'\fR,
+\&\fILINE-NUMBER\fR is the LaTeX source file line number
+of the beginning of the \f(CW\*(C`typoginspect\*(C'\fR environment,
+and \fIPAGE-NUMBER\fR is the page where
+the output of \f(CW\*(C`Text\ and\ code\ to\ investigate\*(C'\fR occurs.
+.PP
+\&\fBtypog-grep\fR reveals the contents of \fILOG-FILE\fR
+between \f(CW\*(C`<typog\-inspect id="\f(CIID\f(CW" ...>\*(C'\fR
+and \f(CW\*(C`</typog\-inspect>\*(C'\fR excluding the XML-tags.

+with the commandline options
+\&\fB\-\-job\-name\fR, \fB\-\-line\-number\fR, and \fB\-\-page\-number\fR, respectively.
+Use \fB\-\-id\fR to show the name of the IDs that matched \fI\s-1REGEXP\s0\fR.
+.PP
+\&\f(CW\*(C`typoginspect\*(C'\fR environments can be nested.
+\&\fBtypog-grep\fR respects the nesting,

+% \LaTeX{} is the beginning of good typesetting -- not the end. This package provides some
+% tools for even better looking documents. When applied correctly its effects appear subtle
+% and inconspicuous.
+%
+%
+% \subsection{Overview}\label{sec:overview}
+%
+% Package~\packagename{typog} focuses on (micro-)typographic improvements.
+%
+% \Cref{sec:information} tends to the wish for more information in the typesetting process
+% whether during the draft phase or in the final printed manuscript.\marginnote{Throughout the
+% whole document we indicate actual uses of the package's features in the margin. All these
+% notes are examples themselves as they are typeset with
+% \hyperref[syn:slightlysloppy]{\code{slightlysloppy}},
+% \hyperref[syn:loosespacing]{\code{loosespacing}}, and
+% \hyperref[syn:smoothraggedrightpar]{\code{smoothraggedrightpar}}.~\visualpar The title page
+% has already demonstrated the effect of
+% \hyperref[syn:lastlinecenteredpar]{\code{lastlinecenteredpar}} in justified paragraphs for
+% the abstract and the copyright notice.}
+%
+% \Cref{sec:latex-hyphenation} expands the hyphenation facilities of \LaTeX.
+%
+% \Cref{sec:break-ligatures,sec:manual-italic-correction,sec:extra-kerning,sec:raise-characters}
+% deal with vertically positioning glyphs in a more pleasant way.
+%
+% \Cref{sec:align-last-line,sec:fill-last-line} discuss dearly missed macros for better control
+% of the last line of a paragraph.
+%
+% \Cref{sec:spacing-control} covers the manipulation of the length of a paragraph.
+%
+% \Cref{sec:microtype-frontend} expounds on the \packagename{microtype} front-end: font
+% tracking~(\ref{sec:tracking-control}), font expansion~(\ref{sec:font-expansion-control}), and
+% character protrusion~(\ref{sec:protrusion}).
+%
+% In \cref{sec:sloppy-paragraphs} we address some shortcomings of spacing control with a
+% replacement for the macro~\cs{sloppy} and the related environment~\code{sloppypar}.
+%
+% \Cref{sec:vtie-paragraph} presents several special functions to avoid club or widow lines in
+% a paragraph.
+%
+% As a simple extension of displayed mathematical equations we define a breakable variant in
+% \cref{sec:breakable-display}.
+%
+% \Cref{sec:setspace-frontend} introduces the \packagename{setspace} front-end.
+%
+% In the last part, \cref{sec:smooth-ragged}, we introduce a novel way of generating ragged
+% paragraphs, which still is experimental.
+%
+%
+% \subsection{Prerequisites}\label{sec:packageprerequisites}
+%
+% Package \packagename{typog} requires \eTeX; it relies on the \LaTeXIII{}~interface. Parts of
+% it are based on package~\packagename{microtype}. However, if the respective functionality is
+% not used, \packagename{typog} can be used without \packagename{microtype}. The same holds
+% true for the \packagename{setspace} front-end.
+%
+% The package was tested with \programname{pdfTeX}~3.141592653-2.6-1.40.24 from the
+% TeX~Live distribution of~2022 as shipped by
+% \href{https://packages.debian.org/search?keywords=texlive}{Debian}.

+% \section{Package Options}\label{sec:package-options}

+% Package \packagename{typog} does not override any existing macros or environments when
+% loaded, unless explicitly told by a package option.

+% Easy things should be easy, and \\
+% hard things should be possible. \\

+% \end{whittyquote}
+%
+% \noindent
+% This is the \doublequotes{User Manual}~section of the documentation, where we describe all
+% user-relevant macros and environments that are defined in package~\packagename{typog}.
+%
+% We follow the naming convention that every environment whose name ends with \code{\dots par}
+% issues a \cs{par} at its end. Environments with different name suffixes never close
+% with~\cs{par}.
+%
+% \bigskip
+%
+% \noindent
+% \DescribeEnv{typogsetup}
+% Configure\index{configuration}\index{setup} the package with the given \meta{keys}. An empty
+% argument of \code{typogsetup} resets all \meta{keys} to their default values.
+%
+% \begin{synopsis}\label{syn:typogsetup}
+% \cs{begin}|{typogsetup}|\marg{keys}
+% \dots{}
+% \cs{end}|{typogsetup}|
+% \end{synopsis}
+%
+% The package can be (re-)configured\index{reconfigure} at any point with
+% \cs{typogsetup}\marg{keys}, or --~for localized changes~-- as
+%
+% \begin{codeexample}
+% 12\=\kill
+% \cs{begin}|{typogsetup}|\marg{keys} \\
+% \> \dots \\
+% \cs{end}|{typogsetup}|
+% \end{codeexample}
+%
+% \noindent
+% where \meta{keys} have the same format as the package options described in
+% \cref{sec:package-options}.
+%
+% \begin{usecases}
+% \cs{typogsetup} can substitute configuring the package at load-time or serve as an
+% addition.~\visualpar Using the |typogsetup|~environment allows to fine-tune the parameters
+% for a specific use, e.\,g., display-sized text.~\visualpar It even is conceivable that a
+% well-established \packagename{typog}-configuration gets attached to font-changing macros
+% like \cs{rm}, \cs{sf},~etc.
+% \end{usecases}
+%
+%
+% \noindent
+% \DescribeMacro{\typogget}
+% Sometimes the user needs to access internal configuration values of
+% package~\packagename{typog}. This can be done in a safe way without resorting to code that
+% is bracketed by \cs{makeatletter}/\cs{makeatother} with the help of the following macro.

+% \cs{hyphenation} and it is defined in package~\packagename{babel}~\cite{package:babel}}. in

+%
+% Let us assume we mark up proper names with

+% \cs{DeclareRobustCommand}*\= \{\cs{propername}\}[1] \\

+% and we want to have hyphenatable \foreignphrase{\doublequotes{\propername{Abel}sche Gruppe}}

+% So, a fictitious macro `\cs{code}' to typeset short pieces of code could look like this:

+% \DescribeMacro{\itcorr*}
+% The italic correction offered by \TeX{} or \LaTeX{} sometimes needs a helping hand.
+%
+% \begin{synopsis}\label{syn:itcorr}
+% \cs{itcorr}\marg{strength} \\
+% \cs{itcorr*}\marg{strength}
+% \end{synopsis}
+%
+% In text mode macro~\cs{itcorr} inserts a kern whose width is proportional to \cs{fontdim1},
+% which is the font's italic correction. If \cs{fontdim1} happens to be zero (e.\,g.~for an
+% upright font), \cs{itcorr} uses the value set with
+% \hyperref[item:textitalicscorrection]{\code{textitalicscorrection}} instead of \cs{fontdim1}.
+% The starred version always uses
+% \hyperref[item:textitalicscorrection]{\code{textitalicscorrection}}. In math mode
+% macro~\cs{itcorr} uses the value set with
+% \hyperref[item:mathitalicscorrection]{\code{mathitalicscorrection}}\footnote{Separate
+% adjustments may be desirable if the math font's italics have markedly different slants.} in
+% both the starred and the unstarred form.
+%
+% Typical slant angles of serif italics fonts range from 8\textdegree{} to~18\textdegree{} and
+% thus values for |textitalicscorrection| from .14 to~.32. Note: \meta{strength} can be
+% negative and fractional \meta{strength}s are allowed.
+%
+% \begin{usecases}
+% Stronger or weaker correction than |\/|.~\visualpar Correct a non-slanted or non-italicized
+% font.~\visualpar Negative correction at the left-hand side\footnote{Groff has the machinery
+% for left-italic-correction. Its font-metrics files support per glyph
+% left-italic-correction values and users can access them conveniently via~\sample*{\cs{,}}.}
+% of italics, i.\,e., compensate \doublequotes{shift-to-the-right effect} of
+% italics.~\visualpar Positive correction at the left-hand side of italics, e.\,g., an
+% opening parenthesis or square bracket followed by an
+% italic~\sample{\itshape\itcorr{8}f\itcorr{7}} (before:~8, after:~7) or
+% \sample{\itshape\itcorr{4}y\itcorr{1}} (before:~4, after:~1) reaching far to the left below
+% the baseline.
+% \end{usecases}
+%
+%
+% \paragraph{The \meta{strength} parameter explained.}
+%
+% \TeX{} records the slant angle~\(\alpha\) of a font in \cs{fontdim1} as \(\mbox{1\,pt} \times
+% \sin\alpha\). Rephrased the formula means: \emph{How much horizontal space is required for a
+% letter slanted with ~\(\alpha\) that is 1\,pt high?} So, \cs{itcorr}\marg{strength}
+% calculates
+% \begin{displaymath}
+% \meta{strength} \times \mbox{1\,pt} \times \sin\alpha.
+% \end{displaymath}
+%
+% A well-chosen \meta{strength} should be the absolute minimum value which avoids that the
+% glyphs typeset in italics collide with other --~usually non-italics~-- letters or symbols
+% unless this disturbs the consistency of the overall tracking.
+%
+% Correction of the right-hand side and \mbox{\(\alpha > 0\)}: A reasonable first guess of
+% \meta{strength} is the highest point where the rightmost part of the letter would touch a
+% rule angled at \(\alpha\) with respect to the baseline. The correction of the left-hand side
+% and \mbox{\(\alpha > 0\)} considers the lowest \singlequotes{touching} point below the
+% baseline on the left-hand side of the letter. Negative values of \(\alpha\) exchange the
+% reference points.

+% \subsection{Apply Extra Kerning}\label{sec:extra-kerning}
+% \index{kerning>extra}
+%
+% Package \packagename{typog} supplies two sets of macros to kern some of the punctuation
+% symbols. One is for forward slashes the other, more extensive one, for hyphens.
+%
+%
+% \subsubsection{Slash}\label{sec:slash-with-kern}
+% \index{kerning>forward slash}
+%
+% \DescribeMacro{\kernedslash}
+% \DescribeMacro{\kernedslash*}
+% Macro~\cs{kernedslash} expands to a forward slash~(\sample{\itcorr{3}\char`/}) with some
+% extra space around it.
+%
+% \begin{synopsis}\label{syn:kernedslash}
+% \cs{kernedslash} \\
+% \cs{kernedslash*}
+% \end{synopsis}
+%
+% The starred form is unbreakable, the non-starred version introduces a break point with
+% penalty~\hyperref[item:breakpenalty]{|breakpenalty|} after the slash. Configure the kerning
+% around the slash with~\hyperref[item:slashkern]{|slashkern|}.
+%
+% If the word following the slash should not be hyphenated append \cs{nobreak} after
+% \cs{kernedslash*}.
+%
+% \begin{usecases}
+% \cs{kernedslash} improves the appearance of pairs of years typeset in lining numerals:
+% \meta{year\textsubscript{1}}/\meta{year\textsubscript{2}}.~\visualpar The macro has proven
+% helpful in many cases where the right hand side of the slash starts with a capital as, for
+% example, \meta{city}/\meta{state-code} (\acronym{US}-specific) or
+% \meta{anything}/\meta{noun} (any language that capitalizes \meta{noun}).
+% \end{usecases}
+%
+%
+% \subsubsection{Hyphen}\label{sec:hyphen-with-kern}
+% \index{kerning>hyphen}
+%
+% \DescribeMacro{\kernedhyphen}
+% \DescribeMacro{\kernedhyphen*}
+% Macros \cs{kernedhyphen*} and \cs{kernedhyphen} expand to a hyphen~(\sample{-}) with given
+% kerning to its left and to its right.
+%
+% \begin{synopsis}\label{syn:kernedhyphen}
+% \cs{kernedhyphen}\oarg{raise}\marg{left-kerning}\marg{right-kerning} \\
+% \cs{kernedhyphen*}\oarg{raise}\marg{left-kerning}\marg{right-kerning}
+% \end{synopsis}
+%
+% Typeset an unbreakable hyphen with \cs{kernedhyphen*} or a breakable hyphen (like \cs{hyp} of
+% package \packagename{hyphenat}~\cite{package:hyphenat}) with \cs{kernedhyphen} and apply some
+% kerning to left and to the right of it. The values \meta{left-kerning} and
+% \meta{right-kerning} are multiplied with one thousandth of the current font's~em to get the
+% size of the kern.
+%
+% The optional argument~\meta{raise}, also given in \nativetextfraction{1}{1000}\,em, allows to
+% adjust the height of the hyphen similar to the macros described in
+% \cref{sec:raise-characters}. In text mode the special argument~\sample{|*|} for \meta{raise}
+% transfers the current value of \hyperref[item:raisecapitalhyphen]{\code{raisecapitalhyphen}}.
+% The default for \meta{raise} is zero.
+%
+% \DescribeMacro{\leftkernedhyphen}
+% \DescribeMacro{\leftkernedhyphen*}
+% \DescribeMacro{\rightkernedhyphen}
+% \DescribeMacro{\rightkernedhyphen*}
+% We also define specialized versions for kerning on the left-hand side or the right-hand side
+% only. These macros work like their two-argument counterparts and set the appropriate other
+% kerning to zero.
+%
+% \begin{synopsis}\label{syn:leftkernedhyphen}\label{syn:rightkernedhyphen}

+% \cs{rightkernedhyphen*}\oarg{raise}\marg{right-kerning}
+% \end{synopsis}
+%
+% \begin{usecases}
+% Composites in the form \meta{math}-\meta{noun} in languages where nouns are
+% capitalized.~\visualpar Composites where one or both sides of the hyphen are typeset in
+% different fonts, like, \meta{small-caps}-\meta{roman}.
+% \end{usecases}
+%
+%
+% \subsection{Raise Selected Characters}\label{sec:raise-characters}
+% \index{raised character}
+%
+% Usually all hyphens and dashes of a font are designed to join lowercase letters. This holds
+% also true for most of our \cs{labelitem}\meta{N} markers, bullets, stars, and even fancy
+% dingbats. If these hyphens and dashes connect uppercase letters (or lining numerals) they
+% sometimes appear to low; they disrespect the glyphs' symmetry axis. A similar situation
+% arises if |itemize|~list markers precede an uppercase letter, a lining numeral, or a big
+% mathematical operator.
+%
+% We introduce a set of macros for the most common cases that allow typsetting these characters
+% at a user definable, adjusted height above the baseline. Users can base their own
+% definitions of raised characters on their associated dimensions.\footnote{Also compare with
+% Ex.~12 in Ref.~\citenum{wermuth:2023} for an attempt to automate vertical alignment.}
+%
+% \begin{caution}
+% The height adjustment disables a font's built-in kerning.
+% \end{caution}
+%
+% \noindent
+% General note for all raised hyphen-like macros: Prefer the starred version if applied in
+% front of any punctuation.
+%
+%
+% \subsubsection{Capital Hyphen}\label{sec:capital-hyphen}
+% \index{raised character>hyphen}
+%
+% \DescribeMacro{\capitalhyphen}
+% \DescribeMacro{\capitalhyphen*}
+% In many fonts the height of the hyphen character~\sample{-} above the baseline is optimized
+% for lowercase letters. In languages that capitalize their nouns as, e.\,g., German, this may
+% be too low for compounds involving capitals.
+%
+% \begin{synopsis}\label{syn:capitalhyphen}
+% \cs{capitalhyphen} \\
+% \cs{capitalhyphen*}
+% \end{synopsis}
+%
+% The unstarred version introduces a hyphenation opportunity right after the hyphen character
+% (with penalty~\hyperref[item:breakpenalty]{|breakpenalty|}) whereas the starred version does
+% not. The actual amount the hyphen gets raised in \cs{capitalhyphen} is determined by
+% \hyperref[item:raisecapitalhyphen]{|raisecapitalhyphen|}.
+%
+% \begin{usecases}
+% In languages that capitalize their nouns, the typical use-case is between an
+% \meta{ab\-bre\-vi\-a\-tion} and a \meta{noun} when \meta{ab\-bre\-vi\-a\-tion} is a string
+% of uppercase letters. The same holds true for a connection of an uppercase variable in
+% mathematical mode and a \meta{noun} starting with a capital letter.~\visualpar Abbreviated
+% compound first names (e.\,g., A.\capitalhyphen* M.~Legendre) can be joined with the starred
+% version.~\visualpar Also, the starred form is suited for \acronym{ISO~8601}-formatted dates
+% if they are composed with lining-style numerals.

+%
+% \paragraph{Interaction with package~\packagename{csquotes}.}

+%
+% The users of package~\packagename{csquotes}
+% can hook up the guillemets as defined by \packagename{typog}
+% with \cs{DeclareQuoteStyle}:
+%
+% \begin{codeexample}
+% 12\=\kill
+% \cs{DeclareQuoteStyle}\{typog-guillemets\} \\
+% \> \{\cs{doubleguillemetright}\}\%\qquad\= opening outer mark \\

+% \> \{\cs{singleguillemetleft}\}\% \> closing inner mark
+% \end{codeexample}
+%
+% \noindent
+% As always, the influence of package~\packagename{babel} on \packagename{csquotes} has to be
+% put into consideration. See Sec.~8 of the \packagename{csquotes}~manual for a description of
+% its configuration possibilities.
+%
+% \begin{usecase}
+% All-capital words as for example acronyms put in guillemets that are raised somewhat almost
+% always look better, whether using the French typographic convention (guillemets pointing
+% outward plus some extra kerning) or the other way round (guillemets pointing inward).
+% \end{usecase}
+%
+% \begin{futuredirection}
+% A correction in the other direction, i.\,e., lowering certain characters may also be

+% option~|fleqn|.\footnote{For displayed equations and \packagename{amsmath} the relevant
+% parameter is~\cs{mathindent}.}
+%
+% \begin{minipage}{\linewidth}
+% A possible remedy is to reflow the paragraph in a way that its last line is clearly wider

+% If the last line of a paragraph is completely filled with text, i.\,e., flush with the

+%
+% \begin{center}
+% \includegraphics{crooked-paragraphs-4.mps}

+% \end{minipage}
+%

+% \packagename{article} uses a \cs{parindent} of~25pt.} for the gap~\cite{carlisle:1996}.
+% \end{enumerate}
+%
+% \begin{tip}
+% In theory both problems, O1 and O2 can be resolved by either shortening or prolonging the
+% last line of the paragraph. For the concrete case it is up to the user to decide which
+% direction to go and to choose the method that yields the most pleasing typographic results.
+%
+% \TeX{} always considers the paragraph in its entirety. Thus any change the user demands
+% \doublequotes{just for the last line} will permeate the whole paragraph and in unfortunate
+% cases botch it.
+%
+% Prudent users check the appearance of the problematic, original paragraph against one or
+% more corrected versions of it~-- at least visually. Quantitative comparisons can be
+% performed with the help of~\cs{tracingparagraphs}.
+% \end{tip}
+%
+% \begin{important}
+% For the techniques in the following two subsections to work the paragraphs treated with
+% them should have certain advantageous properties.
+%
+% \begin{itemize}
+% \item Technically, the paragraphs need to contain enough glue (see
+% e.\,g.~\cref{sec:sloppy-paragraphs}) to achieve a low badness such that the desired
+% paragraph end is deemed feasible by \TeX.
+%
+% \item Aesthetically, the paragraphs must be long enough to absorb the change in last-line
+% fill level otherwise their gray-values visibly deviate from the
+% average.\specialsectionendhere
+% \end{itemize}
+% \end{important}
+%
+%
+% \subsubsection{Manual Changes}\label{sec:fill-last-line-other-methods}
+%
+% Most \hyperref[item:o1]{O1} or \hyperref[item:o2]{O2} situations can be navigated with
+% do-it-yourself methods. Here are some common recipes.
+%
+% \begin{enumerate}
+% \item End-of-paragraph intervention.\label{enum:end-of-paragraph-intervention}
+%
+% \begin{enumerate}[notopsep]
+% \item Tie~\sample{\texttt{\char126}}\label{enum:tie-last-words}\index{paragraph>fill last line>tie}
+%
+% Tie the last words.
+%
+% The problem with the tie may be a hyphenation of one of the words that participates in
+% the tie. The next item avoids this disadvantage.
+%
+% \item \cs{mbox}\label{enum:mbox-last-words}\index{paragraph>fill last line>mbox=\cs{mbox}}
+%
+% Join the last words or inline equation at the end of the paragraph with an~\cs{mbox}.
+%
+% \item \cs{linebreak}\label{enum:linebreak}\index{paragraph>fill last line>linebreak=\cs{linebreak}}
+%
+% Add a \cs{linebreak} to the back part of the paragraph (approximately where the
+% \cs{mbox} of item~\ref{enum:mbox-last-words} would start) in a way that the last line
+% receives the desired length~\cite{wermuth:2022-8-2}. In turn the next-to-last lines
+% may become unsightly. Counteract this degradation e.\,g.~with
+% recipes~\ref{enum:vary-spacing} to~\ref{enum:vary-font-expansion}.
+% \end{enumerate}
+%
+% Tying and \cs{mbox}ing lend themselves to generalizations. We need not only tie at end of
+% a paragraph but fuse logical units of sentences or inline equations so that the relevant
+% information literally stays in the reader's focus. Cementing together text of course finds
+% an end when overfull lines start to show up.
+%
+% \item Uniform paragraph change.\label{enum:uniform-paragraph-change}
+%
+% \begin{enumerate}[notopsep]
+% \item Vary spacing.\label{enum:vary-spacing}\index{font>spacing}
+%
+% Modify the inter-word spacing, for example, with the macros introduced in
+% \cref{sec:looser-tighter-spacing}.
+%
+% Enclose the paragraph in either \hyperref[syn:loosespacing]{|loosespacing|}
+% or~\hyperref[syn:tightspacing]{|tightspacing|}.
+% Increase the spacing~\meta{level} until the last line gets the desired length.
+%
+% \item Vary font tracking.\label{enum:vary-font-tracking}\index{font>tracking}
+%
+% Enclose the paragraph in a \hyperref[syn:setfonttracking]{\code{setfonttracking}}~group.
+% See \cref{sec:tracking-control}. Increase or decrease the tracking in steps of
+% \nativetextfraction{1}{1000}\,em until the last line looks good.
+%
+% \item Vary font expansion.\label{enum:vary-font-expansion}\index{font>expansion}
+%
+% Enclose the paragraph in a \hyperref[syn:setfontexpand]{\code{setfontexpand}}~group. See
+% \cref{sec:font-expansion-control}.
+% \end{enumerate}
+%
+% \item A combination of any of the above items.
+%
+% \item Some curveballs.\label{enum:gonzo-tips}\par
+% \begin{enumerate}[notopsep]
+% \item If the paragraph already suffers from one of the problems that \TeX{} addresses with
+% \cs{doublehyphendemerits}, \cs{finalhyphendemerits}, or~\cs{adjdemerits}, crank up one or
+% all of these values to~10000 and observe whether the length of last line changes in the
+% desired direction.
+%
+% \item If any influential \packagename{microtype} features have been enabled try with one
+% more more of them \emph{disabled}. See, e.\,g.,
+% environment~\hyperref[syn:nofontexpansion]{\code{nofontexpansion}} in
+% \cref{sec:font-expansion-control}.
+% \end{enumerate}
+% \end{enumerate}
+%
+%
+% \subsubsection{Multi\capitalhyphen Purpose Environments}\label{sec:fill-last-line-gp-environments}
+%
+% \DescribeEnv{shortenpar}
+% \DescribeEnv{prolongpar}
+% The two environments |shortenpar|\index{paragraph>fill last
+% line>shortenpar=\code{shortenpar}} and |prolongpar|\index{paragraph>fill last
+% line>prolongpar=\code{prolongpar}} can be employed in quite general situations when a
+% paragraph should be typeset one line longer or shorter, e.\,g., to avoid a
+% widow~line\footnote{The last line of a paragraph becomes a \singlequotes{widow}\index{forlorn
+% line>widow} (ger.~\foreignphrase{Hurenkind}) if it starts the following page or column.} or
+% a club~line\footnote{The first line of a paragraph is called
+% \singlequotes{club}\index{forlorn line>club} or~\singlequotes{orphan}\index{forlorn
+% line>orphan} (ger.~\foreignphrase{Schusterjunge}) if it appears at the bottom of the page or
+% column.}~[\citenum{knuth:1986}, p.~104 and~\citenum{mittelbach:2018c}]. (See also
+% \cref{sec:vtie-paragraph} for special functions to avoid clubs or widows.)
+% \singlequotes{Accidentally}, they also change the length of the last line of the paragraph.
+%
+% \begin{synopsis}\label{syn:shortenpar}
+% \cs{begin}|{shortenpar}|
+% \dots{}
+% \cs{end}|{shortenpar}|
+% \end{synopsis}
+%
+% Environment |shortenpar| decreases the \cs{looseness} of the paragraph.\footnote{Command
+% \cs{looseness} is a \TeX{}~primitive~\cite[p.~103n]{knuth:1986}. A thorough discussion of
+% the interaction of \cs{linepenalty} and \cs{looseness} can be found in
+% Ref.~\citenum{wermuth:2017c}.} It performs well if the last line of the paragraph is short
+% or the whole paragraph is loose.
+%
+% \begin{synopsis}\label{syn:prolongpar}
+% \cs{begin}|{prolongpar}|
+% \dots{}
+% \cs{end}|{prolongpar}|
+% \end{synopsis}
+%
+% This environment increases the \cs{looseness} of the paragraph, which is why it works best
+% with decent or tight last lines that are almost full.
+%
+%
+% \subsubsection{Specialized Environments}\label{sec:fill-last-line-specialized-environments}
+%
+% We introduce environments not just skips to get the correct behavior --~set up all paragraph
+% parameters \emph{before} the paragraph ends~-- and, at the same time, limit the range of this
+% parameter change.
+%
+% \DescribeEnv{covernextindentpar}
+% Environment |covernextindentpar|\index{paragraph>fill last line>covernextindentpar=\code{covernextindentpar}}
+% can be helpful for \hyperref[item:o1]{case~O1}, i.\,e., a too short last line.
+%
+% \begin{synopsis}\label{syn:covernextindentpar}
+% \cs{begin}|{covernextindentpar}|\oarg{dim} \\
+% \hspace*{1em}\dots \\
+% \cs{end}|{covernextindentpar}|
+% \end{synopsis}
+%
+% The environment asks \TeX{} to extend the last line of a paragraph such that it takes at
+% least
+% \makeatletter\dumpmacro{\typog at covernextindentpar@nonzero at parindent}\makeatother{}
+% (if \(\cs{parindent} \not= 0\)),
+% \makeatletter\typog at covernextindentpar@zero at parindent\makeatother{}
+% (if \(\cs{parindent} = 0\)), or \meta{dim} if called with an optional argument.
+%
+% \DescribeEnv{openlastlinepar}
+% The next environment, |openlastlinepar|,\index{paragraph>fill last
+% line>openlastlinepar=\code{openlastlinepar}} takes care of \hyperref[item:o2]{case~O2},
+% i.\,e., a last line in a paragraph that is almost full or completely filled.
+%
+% \begin{synopsis}\label{syn:openlastlinepar}
+% \cs{begin}|{openlastlinepar}|\oarg{dim} \\
+% \hspace*{1em}\dots \\
+% \cs{end}|{openlastlinepar}|
+% \end{synopsis}
+%
+% It may resolve \hyperref[item:o2]{case~O2} as it attempts to prevent a completely filled line
+% by introducing a partly unshrinkable \cs{parfillskip}. Without optional argument the
+% threshold of unused last-line length is either
+% \makeatletter\dumpmacro{\typog at openlastlinepar@nonzero at parindent}\makeatother{} (if
+% \(\cs{parindent} \not= 0\)) or
+% \makeatletter\typog at openlastlinepar@zero at parindent\makeatother{} (if \(\cs{parindent} = 0\)).
+% The optional argument~\meta{dim} directly sets the gap threshold.
+%
+% Note that the application of this environment can be successful, this is, a completely filled
+% last line is avoided, but the result may be of \hyperref[item:o1]{type~O1} nonetheless.

+% The environments in this section directly influence the spacing, this is, they change the

+% The latter also being important to ensure the monotonicity of the different \meta{level}s.

+% The \cs{widespace} macro and its companion \cs{narrowspace} derive their appearances from
+% several of the current font's \cs{fontdimen}\meta{number}s. \TeX{} addresses the latter by
+% integers, which is totally non-memnonic. Therefore, we play softball by first presenting
+% \cref{tab:fontdimen} that associates the \cs{fontdimen}\meta{number}s with their meanings and
+% also reports on their current values (for this document).\footnote{The association is given
+% in Appendix~F (p.~433) of Ref.~\citenum{knuth:1986}. For a concise and understandable
+% explanation of the \TeX~\cs{fontdimen} parameters consult Ref.~\citenum{carlisle:2013}.}

+% \end{equation*}
+%

+% Its width is independent of any \cs{frenchspacing} or \cs{nonfrenchspacing}~settings, but

+% \subsection{Vertically Partially-Tied Paragraphs}\label{sec:vtie-paragraph}\index{paragraph>vertically tied}
+%
+% \LaTeX{} provides several macros and environments to tie material vertically~-- most
+% prominently |samepage| and |minipage|.\footnote{A valuable complement to these is
+% package~\packagename{needspace}~\cite{package:needspace} which takes a different approach and
+% reliably works in \emph{mixed} horizontal and vertical mode situations.}
+% \packagename{Typog's} macros and environments constitute more sophisticated but weaker forms
+% of these. They tie only the first or last couple of lines in a paragraph while the rest of
+% the paragraph gets broken into pages by \TeX{} in the usual way.
+%
+% The macros and environments described in this section locally set \eTeX{} penalty
+% arrays~\cite[Sec.~3.8]{package:etex}. In addition the environments~\code{vtietoppar},
+% \code{vtiebotpar}, and~\code{vtiebotdisptoppar} explicitly issue a \cs{par} at the end of the

+%
+% Package \packagename{setspace} \cite{package:setspace} is a base hit when it comes to
+% consistently setting the line skip for a document via the macro~\cs{setstretch}. The
+% interface of \cs{setstretch} though is unintuitive as it asks for an obscure
+% factor.\fontsizeinfo{setspacefontsizeinfo}\marginnote{In the copy of this document gets
+% typeset with~\setspacefontsizeinfo*.} The \LaTeX{} user however prefers to keep her eyes on
+% the ball and set the line skip\index{baseline skip} directly (e.\,g.~12.5pt) or the lines'
+% leading\index{leading} to a length or percentage of the font's size.\footnote{To find out
+% about the current font's size and the \cs{baselineskip} in printable form check out
+% \cref{sec:font-information} on \cpageref{sec:font-information}.} This is where the following
+% macros go to bat.
+%
+% \begin{important}
+% All macros that are introduced in this section rely on macro~\cs{setstretch}. So
+% package~\packagename{setspace} must have been loaded with
+%
+% \begin{codeexample}
+% \cs{usepackage}\{setspace\}
+% \end{codeexample}
+%
+% \noindent
+% in the document preamble.
+% \end{important}
+%
+% \DescribeMacro{\setbaselineskip}

+% Set the line skip using an absolute length -- technically: a |dimen|.
+%
+% \begin{synopsis}\label{syn:setbaselineskip}
+% \cs{setbaselineskip}\marg{baseline-skip}
+% \end{synopsis}
+%
+% Set the \cs{baselineskip} to \meta{baseline-skip}. This is what a non-initiated user expects
+% from the assignment
+%
+% \begin{codeexample}
+% \cs{setlength}\{\cs{baselineskip}\}\{\meta{baseline-skip}\}
+% \end{codeexample}
+%
+% The \meta{baseline-skip} can contain a rubber (stretch/shrink) component, however,
+% \cs{setbaselineskip} will discard of it and issue a warning that only the fixed-length part
+% will be used in the computation.
+%
+% \begin{example}
+% Let us assume we want to lighten the gray value of the copy a tad with a \cs{baselineskip}
+% increased (from e.g.~12pt) to~12.5pt. To this end we say:
+%
+% \begin{codeexample}
+% \cs{setbaselineskip}\{12.5pt\}\specialsectionendhere
+% \end{codeexample}
+% \end{example}
+%
+% \begin{tip}
+% To set the \cs{baselineskip} relative to the current value use
+%
+% \begin{codeexample}
+% \cs{setbaselineskip}\{\meta{factor}\cs{baselineskip}\}

+%
+% \noindent
+% where \meta{factor} is a floating-point number.

+%
+% \begin{synopsis}\label{syn:resetbaselineskip}
+% \cs{resetbaselineskip}
+% \end{synopsis}
+%
+% This macro simply expands to |\setstretch{1}|. So, we rely on \packagename{setspace}'s

+%
+%
+% \DescribeMacro{\setbaselineskippercentage}

+% \end{synopsis}
+%
+% Set \cs{baselineskip} to \(\cs{typogfontsize} \times \meta{baselineskip-percentage} / 100\).
+%
+% \begin{example}
+% We modify the previous example and assume a font design size of 10pt, but now write
+%
+% \begin{codeexample}
+% \cs{setbaselineskippercentage}\{125\}
+% \end{codeexample}
+%
+% \noindent
+% which sets \cs{baselineskip} to \(10\text{pt} \times 125 / 100 = 12.5\text{pt}\).
+% \end{example}
+%
+% \DescribeMacro{\setleading}
+% \sinceversion{Since v0.3}
+% Set the \cs{baselineskip} with an absolute length that gets \emph{added to} \cs{typogfontsize}.

+% \begin{synopsis}\label{syn:setleading}

+% \end{synopsis}
+%
+% Set the \cs{baselineskip} to \cs{typogfontsize} plus \meta{leading}. Note that
+% \meta{leading} can be negative, e.\,g.~to set solid.
+%
+% \begin{example}
+% Another solution of the previous example, given a font design size of 10pt is to write
+%
+% \begin{codeexample}
+% \cs{setleading}\{2.5pt\}
+% \end{codeexample}
+%
+% \noindent
+% which sets \cs{baselineskip} to \(10\text{pt} + 2.5\text{pt} = 12.5\text{pt}\).
+% \end{example}
+%
+% \DescribeMacro{\setleadingpercentage}
+% \sinceversion{Since v0.3}

+%
+% \begin{synopsis}\label{syn:setleadingpercentage}
+% \cs{setleadingpercentage}\marg{leading-percentage}
+% \end{synopsis}
+%
+% Set \cs{baselineskip} to \(\cs{typogfontsize} \times (1 + \meta{leading-percentage} / 100)\).
+%
+% \begin{example}
+% We modify the previous example and again assume a font design size of 10pt, but now write
+%
+% \begin{codeexample}

+%
+% \smallskip
+%
+% \DescribeLaTeXDimen{\typogfontsize}
+% \sinceversion{Since v0.3}
+% The macros \cs{setbaselineskippercentage}, \cs{setleading}, and \cs{setleadingpercentage} all
+% depend on the font size. By changing \cs{typogfontsize} they can be configured for different
+% font sizes.
+%
+% The length \cs{typogfontsize} gets initialized at the end of the preamble to the default
+% font's quad size:\footnote{For an overview of the various
+% \cs{fontdimen}\meta{number}~parameters consult \cref{tab:fontdimen} on
+% \cpageref{tab:fontdimen}.}
+%
+% \begin{codeexample}
+% \cs{typogfontsize}=\cs{fontdimen6}\cs{font}
+% \end{codeexample}
+%
+% \noindent
+% which is also called its \doublequotes{nominal size} or its \doublequotes{design size}. This
+% assignment can be repeated at any point in the document to record a reference font's size.
+% To set just \cs{typogfontsize} without changing the current font, encapsulate the font change
+% in a group and export the new value:
+%
+% \begin{codeexample}
+% \cs{begingroup} \\
+% ~~\cs{usefont}\{T1\}\{Arvo-TLF\}\{m\}\{n\}\cs{selectfont} \\
+% ~~\cs{normalsize} \\
+% ~~\cs{global}\cs{typogfontsize}=\cs{fontdimen6}\cs{font} \\
+% \cs{endgroup}
+% \end{codeexample}
+%
+% An alternative to relying on the design size is using the actual size of an uppercase letter:
+%
+% \begin{codeexample}
+% \cs{settoheight}\{\cs{typogfontsize}\}\{CEMNORSUVWXZ\}
+% \end{codeexample}
+%
+% \noindent
+% With \cs{typogfontsize} defined this way it becomes trivial to set solid:
+%
+% \begin{codeexample}
+% \cs{setleading}\{0pt\}
+% \end{codeexample}
+%
+% \noindent
+% or
+%
+% \begin{codeexample}
+% \cs{setleadingpercentage}\{0\}
+% \end{codeexample}
+%
+% \begin{tip}
+% All macros in this section actually accept expressions of their respective argument types,

+% \paragraph{Global Parameters}
+%
+% \begin{description}[style=nextline]
+% \item[\cs{smoothraggedrightfuzzfactor}=\meta{factor}]
+% The environment adds glue to every line-width\footnote{The shortest line only gets
+% stretchability, the longest only receives shrinkability. All other lines are both
+% stretchable and shrinkable.} to achieve a more convincing \doublequotes{ragged appearance}
+% and to reduce the number of overfull lines. The algorithm divides the smooth margin into
+% 3, 5, or~7 parts depending on the chosen \cs{smoothraggedrightgenerator} (see below). The
+% \cs{smoothraggedrightfuzzfactor} is the amount of glue of each line expressed as a multiple
+% of the distance between the division points. The default of 1.0 means to add as much glue
+% such that the lines just do not overlap (assuming justification is feasible).
+%
+% \item[\cs{smoothraggedrightgenerator}]
+% Select a generator to use. Valid generator names:
+% \begin{itemize}[noitemsep]
+% \item |triplet|,
+% \item |quintuplet|,
+% \item |septuplet|.
+% \end{itemize}
+%
+% The default generator is |triplet|.
+%
+% \item[\cs{smoothraggedrightleftskip}=\meta{dim}]
+% Value for |leftskip| to pass to the generator. Default:~0pt.
+%
+% \item[\cs{smoothraggedrightparindent}=\meta{dim}]

+=head1 NAME
+
+typog-grep - grep for typog-inspect elements in LaTeX log files
+
+
+=head1 SYNOPSIS
+
+=over
+
+=item B<typog-grep> -a|--all|--any [I<OPTION>...] F<LOG-FILE>...
+
+=item B<typog-grep> [I<OPTION>...] I<REGEXP> F<LOG-FILE>...
+
+=back
+
+The first form shows all C<E<lt>typog-inspect id="I<ID>" ...E<gt>> elements in F<LOG-FILE>.
+
+The second form shows the contents of C<E<lt>typog-inspect id="I<ID>" ...E<gt>> elements
+whose I<ID>s match I<REGEXP> in F<LOG-FILE>.
+
+If no F<LOG-FILE> is given read from F<stdin>.
+The S<filename C<->> is synonymous to F<stdin>.
+
+
+=head1 DESCRIPTION
+
+B<typog-grep> is a tailored post-processor for LaTeX log files
+and the C<typoginspect> environment as provided by S<package typog>.
+It shares more with the venerable
+L<B<sgrep>|https://www.cs.helsinki.fi/u/jjaakkol/sgrep.html>
+than with S<POSIX L<B<grep>|https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html>>.
+
+The LaTeX user brackets her text in
+
+ \begin{typoginspect}{ID}
+ Text and code to investigate
+ \end{typoginspect}
+
+where I<ID> is used to identify one or more bracketed snippets.
+I<ID> does not have to be unique.
+The I<REGEXP> mechanism makes it easy to select groups of related I<ID>s
+if they are named accordingly.
+
+In F<LOG-FILE> the environment shows up, packed with tracing information, as
+
+=begin texinfo
+
+ at display
+ at relax
+
+=end texinfo
+
+ <typog-inspect id="ID" job="JOB-NAME" line="LINE-NUMBER" page="PAGE-NUMBER">
+ Trace Data
+ </typog-inspect>
+
+=begin texinfo
+
+ at end display
+ at relax
+
+=end texinfo
+
+where all the capital-letter sequences are meta-variables
+and in particular
+I<JOB-NAME> is the expansion of C<\jobname>,
+I<LINE-NUMBER> is the LaTeX source file line number
+of the beginning of the C<typoginspect> environment,
+and I<PAGE-NUMBER> is the page where
+the output of S<C<Text and code to investigate>> occurs.
+
+B<typog-grep> reveals the contents of F<LOG-FILE>
+between C<E<lt>typog-inspect id="I<ID>" ...E<gt>>
+and C<E<lt>/typog-inspectE<gt>> excluding the XML-tags.
+Access the I<JOB-NAME>, I<LINE-NUMBER>, and I<PAGE-NUMBER>
+with the commandline options
+B<--job-name>, B<--line-number>, and B<--page-number>, respectively.
+Use B<--id> to show the name of the IDs that matched I<REGEXP>.
+
+C<typoginspect> environments can be nested.
+B<typog-grep> respects the nesting,
+i.e., if the I<ID> of the nested environment does not match I<REGEXP>
+it will not be included in the program's output.
+
+
+=head1 OPTIONS
+
+The list of options is sorted by the names of the long options.
+
+=over 4
+
+=item B<-a>, B<--all>, B<--any>
+
+ID-discovery mode:
+Show all C<typog-inspect> elements independent of any matching patterns.
+
+=item B<--color>, B<colour> I<WHEN>
+
+Colorize specific log contents for the matching ids.
+The S<argument I<WHEN>> determines when to apply color:
+C<always>, C<never>, S<or C<auto>>.
+The setting C<auto> checks whether standard output has been redirected.
+This is the default.
+
+=item B<-C>, B<--config> I<KEY>=I<VALUE>[:I<KEY>=I<VALUE>[:...]]
+
+Set one or more configuration I<KEY> to I<VALUE> pairs.
+See S<Sec. CONFIGURATION> below for a description of all available configuration items.
+Use option B<--show-config> to display the default configuration.
+
+=item B<--debug>
+
+Turn on debug output on F<stderr>.
+
+=item B<-h>, B<--help>
+
+Display brief help then exit.
+
+=item B<-i>, B<--[no-]id>
+
+Print the actual id name that matched I<REGEXP>.
+Control the appearance of the matching id with configuration S<item C<id-heading>>.
+
