% \begin{abstract}
%   \pkg{ekdosis} is a Lua\LaTeX{} package designed for multilingual
%   critical editions. It can be used to typeset texts and different
%   layers of critical notes in any direction accepted by
%   Lua\TeX. Texts can be arranged in running paragraphs or on facing
%   pages, in any number of columns which in turn can be synchronized
%   or not. In addition to printed texts, \pkg{ekdosis} can convert
%   \texttt{.tex} source files so as to produce \texttt{TEI
%   xml}-compliant critical editions. Database-driven encoding under
%   \LaTeX{} then allows extraction of texts entered segment by
%   segment according to various criteria: main edited text, variant
%   readings, translations or annotated borrowings between texts. It
%   is published under the terms of the GNU General Public License
%   (GPL) version 3.

% \lettrine{\color{cinnamon}\missaali +T+}{he reader} will find here,
% by way of introduction, a summarized version of the first part of an
% article published in the
% \mkbibemph{\citefield{Alessi2020}{journaltitle}} as a contribution
% to a Digital Humanities workshop held at Stanford University
% (\printdate{2019-04-15}).\footcite{Alessi2020}
%
% The name of this package, \pkg{ekdosis}, derives from a Greek
% action noun\---\sg{ἔκδοσις}\---the meaning of which is:
% \enquote{publishing a book}, and also in concrete sense: \enquote{a
% publication, treatise}. For us moderns, this term refers to a long
% tradition of scholarly work consisting in establishing from
% manuscript evidence the texts of Greek and Latin classics that were
% handled down through the Middle Ages to the time of the first
% printed editions. Of course, this definition is extendible to other
% languages as well. The basic premise is that critical editions
% exhibit reconstructed texts from manuscript evidence either under
% the title of the edited text (direct tradition) or from explicit
% citations or parallel passages or translations in other languages
% (indirect tradition).
%
% Whether in print or digital, critical editions come with an
% apparatus criticus in which is mentioned all the evidence that was
% used to build the edited text. Arguably, it is precisely on this
% common point that the two kind of editions part ways for reading a
% traditional, well written apparatus criticus is only meant for
% experienced readers. Getting oneself familiarized with its many
% conventional rules is not unrelated to learning a language, equipped
% with technical terms, grammar rules and style embellishments, which
% came into existence out of over three centuries of scholarly
% attainments. Nevertheless, whereas this language is immediately
% accessible to human mind's ability to use language and interpret
% conventional symbols, it is quite inaccessible to a computer unless
% every item of information has been encoded in the rather dumb format
% that is suited to machines.
%
% On the other hand, editions in print have their own limitations. For
% example, every detail that editors of classical texts decide to
% discard to save space, regardless to its relevance to the purpose of
% the edition, is lost permanently as in the case of dialectal
% coloring of ancient books. Furthermore, passages collected as
% indirect tradition are only available as references in the
% \emph{apparatus testium} and cannot be referred to the original
% text. As a result, the reader is refrained from bestowing attention
% upon major parallel passages to understand better difficult passages.
%
% To conclude on these issues, print publications and digital editions
% are often contrasted as they belonged to two different
% worlds.\footnote{For a good illustration of this point, see
% \cite[\mkbibquote{Content, not Display}]{DLL-TC}.}  It is commonly
% said that the content of editions in print is the result of the
% binding of the book itself as an object, whereas digital editions,
% in which format and presentation are by definition separated from
% content, are free from limitations coming from such bindings. To sum
% up from the foregoing considerations, this statement is likely to be
% qualified: as already seen above, the apparatus criticus must be
% looked at as a brilliant production of mind refined by centuries of
% scholarly tradition\---and surely tradition must go on\---arguably
% not as compact paragraphs that require special and painful training
% to be \enquote*{decoded}. On the other hand, what editions in print
% do not provide are what \citename{Mastronarde.Tarrant2017}{author}
% have called \enquote{actionable texts for use in digital research},%
% {\interfootnotelinepenalty=10000\footcite{Mastronarde.Tarrant2017}}
% namely database-driven texts allowing the reader to select
% annotations and display or arrange translations, parallel passages
% or borrowings in a variety of ways.
% 
% \pkg{ekdosis} can be seen as an attempt at combining the two
% approaches.
%
% \subsection{Requirements}
% \label{sec:requirements}
% Please refer to \vref{ref:ekdrequirements}.
%
% \subsection{Features}
% \label{sec:features}
% A list of the main features of \pkg{ekdosis} follows:---
% \begin{enumerate}
% \item \phts\label{it:multicol-feature}\emph{Multilingual critical
%   editions\/}: \pkg{ekdosis} can be used to typeset any number of
%   texts in any direction accepted by \hologo{LuaTeX}. Running
%   paragraphs of text can be arranged in any number of columns,
%   either on single or facing pages, which in turn can be
%   synchronized or not. \pkg{ekdosis} is also suitable for complex
%   layouts as in the case of Arabic poetry or images where three-way
%   alignment is required, or diagrams, \emph{\&c}.
% \item \phts\label{it:multilayer-feature}\emph{Apparatus criticus\/}:
%   Edited texts can receive multiple layers of apparatus, e.g.\
%   apparatus criticus (to record variant readings), apparatus fontium
%   (to collect references to texts quoted or cited in the edited
%   text), apparatus testium (to collect testimonia or parallel
%   passages), or any kind of short notes to be printed on the same
%   page as the edited text, \emph{\&c}.
% \item \texttt{TEI xml} output: \pkg{ekdosis} can be instructed to
%   output both PDF and \texttt{TEI xml} files at the same time.
% \item \emph{Database-driven encoding} under \LaTeX{} of texts

% \end{enumerate}
%
% Before going into detail, the following simple example will give the
% reader a general idea of the method of encoding with
% \pkg{ekdosis} authoritative texts composed of lemmata, in a way
% that is very close to \texttt{TEI xml} encoding:---

% \fi
%
% As can be seen from \vref{lst:pj1}, the edition text is inserted in
% the \env{ekdosis} environment (ll.~\lnref{ln:pj1:1} to
% \lnref{ln:pj1:8}). Then two \cs{app}\marg{apparatus entry}
% commands (ll.~\lnref{ln:pj1:3} and \lnref{ln:pj1:7})
% contain the lemma (\cs{lem}\marg{lemma}), namely the reading that is
% accepted by the editor, and at least one variant reading
% (\cs{rdg}\marg{reading}, ll.~\lnref{ln:pj1:5} and
% \lnref{ln:pj1:7}). As the listing shows, the editor is free
% to lay out the code in a legible manner to the eye: the first lemma
% above spans several lines whereas the second one is written in
% sequence without spaces.
%
% In the PDF output, the edition text is printed in the upper part of
% the page, above the line, and naturally shows the accepted
% readings. The margins are used for numeration. In the apparatus
% criticus, below the line, reference to the text is made by
% specifying the number of the line and if several entries refer to
% the same line, numbers are not repeated. Instead, entries are
% separated from one another by a broad horizontal space. Finally, a
% square bracket is used inside entries to distinguish the lemma from
% the variant readings.
%
% Furthermore, as said above, if a \texttt{TEI xml} output be
% required, \pkg{ekdosis} compiles an additional |.xml| file an
% excerpt of which is provided above.

% \section{The Basics of \pkg{ekdosis}}
% \label{sec:ekdosis-basics}
%
% \subsection{Loading the Package\---General Options}
% \label{sec:load-general-options}
%
% \pkg{ekdosis} is loaded in the preamble like so:---
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\usepackage{ekdosis}
\end{minted}
% \iffalse
%</example>
% \fi
% 
% \pkg{ekdosis} may be loaded with five optional \enquote*{named
% arguments} either of which is set using the syntax
% \meta{key}$=$\meta{value}. The description of the optional arguments
% follows.
%
% \danger The reader is invited to refer to the relevant sections of
% this documentation for more information on how to use these options.
% 
% \DescribeOption{layout}\phts\label{ref:layout-opt}
% |layout|$=$\verb+float|footins|keyfloat|fitapp+
% \hfill\tcboxverb{Default: float}
% \begin{enumerate}
% \item |layout=float| By default, layers of critical notes are
%   inserted as floating environments to be printed at the bottom of
%   the pages.
% \item |layout=footins| This can be set to insert critical notes in
%   the default footnote block which can be considered to be a special
%   kind of float that is printed at the bottom of the pages. In this
%   case, the apparatus criticus will be inserted between regular
%   numbered footnotes, but will carry no footnote mark of its own.
% \item \label{ref:keyfloat-opt}\newfeature[v1.3] |layout=keyfloat|
%   does approximately the
%   same as the default option |layout=float| but uses the
%   \pkg{keyfloat} package\footcite{keyfloat} to generate the floating
%   environments to be used as containers for critical footnotes. This
%   way, the keys and values provided by this
%   package\footcite[See][sect. 2.3, \ppno~13--16]{keyfloat} may be
%   used to achieve such effects as append additional, informative
%   text below the apparatus, draw a line around the apparatus block
%   or change its width.\footnote{See below, \vpageref{ref:keyparopts}
%   for more information.}
% \item \label{ref:fitapp-opt}\newfeature[v1.3] |layout=fitapp| As
%   described below in \vnref{sec:oscillating-problem}, \pkg{ekdosis}
%   may oscillate indefinitely between different sets of page
%   decisions when one or more apparatus entries attached to the last
%   lines of the edition text on a given page do not fit in the
%   apparatus block. The reader will find in this section of the
%   documentation a detailed account of several ways to circumvent
%   this issue. Alternatively, or rather conjointly with those ways,
%   |layout=fitapp| can be used to instruct \pkg{ekdosis} to scale
%   down the characters of the apparatus block so that the contentious
%   entries can fit. This mechanism uses the \enquote{fitting} library
%   provided by the \pkg{tcolorbox} package.\footcite[sect.~22,
%   \ppno~\pnfmt{438--449}]{tcolorbox} When this option is set, the
%   apparatus criticus grows normally until a predefined height is
%   reached. This height is set to |0.5\textheight| by
%   default.\footnote{Of course, this height can be modified. See
%   below \vpageref{ref:appheight} for details.} From this point on,
%   the apparatus block ceases to grow; rather, the size of the
%   characters is reduced to allow for additional entries. As a
%   consequence of this rationale, the total number of entries on a
%   given page must not be too high. It is therefore advisable to use
%   |layout=fitapp| conjointly with |maxentries| as described below on
%   pages~\pageref{ref:glimit} and~\pageref{ref:maxentries} and in
%   \vref{sec:oscillating-problem}.
%   \danger If used appropriately, this mechanism gives excellent
%   typographical results, notably with complex edition texts of which
%   the entries in the associated apparatus can be quite abundant in
%   number. It may even put an end to the
%   \enquote{\hyperref[sec:oscillating-problem]{oscillating problem}}
%   in most of the cases. However, as suitable it may be for high
%   quality typeset texts and final, camera-ready copies, its benefit
%   comes at the expense of slowing down the compilation process. Yet
%   looser algorithms can be selected when speed must prevail over
%   quality for intermediate or draft copies.\footnote{See below
%   \vpageref{ref:fitalgorithm} for more information.}
% \end{enumerate}
%
% \DescribeOption{divs}\phts\label{ref:divs-opt}
% |divs|$=$\verb+ekdosis|latex+\hfill\tcboxverb{Default: ekdosis}\\
% In many occasions, \LaTeX{} standard textual divisions do not meet
% the specific requirements of classical and literary texts, the
% divisions of which may depend on many different received
% traditions. \pkg{ekdosis} provides a flexible mechanism in which
% format and presentation have been carefully separated from
% content. It is designed to build un-numbered \texttt{TEI} divisions
% allowed to nest recursively.\footnote{See below,
% \vref{sec:body-divisions}.} However, if |divs| be set to |latex|,
% \LaTeX{} standard textual divisions can be used and will be
% translated into \texttt{TEI} numbered |<div>| elements.
%
% \danger It must be noted that the two styles are mutually exclusive.
% \vskip\baselineskip
%
% \DescribeOption{poetry}\phts\label{ref:poetry-opt}
% \newfeature[v1.2] |poetry|$=$\verb+verse+
% \hfill\tcboxverb{Default: not set}\\
% |poetry=verse| instructs \pkg{ekdosis} to load and use the facilites
% supplied by the \pkg{verse} package for the typesetting of lines of
% poetry.\footnote{\texttt{verse} does not need to be set if the
% \cls{memoir} class be used. See \vref{sec:verse-package} for more
% detail.} The \env{ekdverse} environment must then be used instead of
% the \env{verse} environment that is provided by the \pkg{verse}
% package as described below in \vref{sec:verse-package}.
%
% \DescribeOption{parnotes}\phts\label{ref:parnotes-opt}
% |parnotes|$=$\verb+true|false|roman+%
% \hfill\tcboxverb{Default: not set}\\
% This named argument does not need a value as it defaults to |true|
% if used. Apparatus criticus typeset by \pkg{ekdosis} may contain
% notes and footnotes. The latter can be laid out as paragraphed notes
% below the block of critical notes by means of the \pkg{parnotes}
% package. Additionally, |parnotes=roman| prints these footnotes
% numbered with Roman numerals.
%
% \DescribeOption{teiexport}\phts\label{ref:teiexport-option}
% |teiexport|$=$\verb+true|false|tidy+%
% \hfill\tcboxverb{Default: not set}\\
% This named argument does not need a value as it defaults to |true|
% if used. If |teiexport| be set to |true|, \pkg{ekdosis} is
% instructed to output both PDF and \texttt{TEI xml} files at the same
% time. By default, the \texttt{TEI} file will receive the same
% basename as the |.tex| source file, suffixed with |-tei.xml|. The
% raw |.xml| file that is produced by \pkg{ekdosis} can be further
% processed by the \textsf{tidy} console application.\footnote{See
% \url{http://www.html-tidy.org}.} To make this happen, \textsf{tidy}
% must be installed and the |.tex| source file must be compiled with
% the |--shell-escape| facility so that spawning programs from
% \LaTeX{} can be allowed.\footnote{See
% \url{https://texfaq.org/FAQ-spawnprog} for more information on how
% to do this.}
%
% As an example, the following line loads \pkg{ekdosis} and instructs
% it to output a \texttt{TEI xml} file (in addition to the PDF one)
% and to use \pkg{parnotes} to format with Roman numerals the footnotes
% that are inserted in the apparatus criticus:---
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\usepackage[teiexport, parnotes=roman]{ekdosis}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \subsection{Setup}
% \label{sec:setup}
% \DescribeMacro{\ekdsetup} \newfeature[v1.3] Starting from v1.3,
% \cs{ekdsetup} can be used to specify options that affect the general
% behavior of \pkg{ekdosis}. \cs{ekdsetup} is a preamble-only
% command. It accepts the following |key=value| options the number of
% which is expected to increase as \pkg{ekdosis} grows:\\
% \DescribeOption{showpagebreaks}\phts\label{ref:showpagebreaks-opt}
% \unskip|showpagebreaks|$=$\verb+true|false+
% \hfill \tcboxverb{Initially: false; Default: true}\\
% This named argument, which defaults to |true| if used without value,
% has specific marks printed in the margins so as to spot with a rapid
% cast of the eye the locations of conditional page breaks generated
% by the \cs{ekdpb} command described below \vpageref{ref:ekdpb}. By
% default, page breaks generated by \cs{ekdpb} are identified by the
% string |spb|\===for \enquote{soft} page break\=== whereas those
% generated by \cs{ekdpb*} are identified by |hpb|\===for
% \enquote{hard} page break. Furthermore, when \cs{ekdpb} triggers no
% page break, the marker is printed between square brackets, like so:
% |[spb]|. In this
% way, inoperative \cs{ekdpb} can be easily spotted and removed.\\
% \DescribeOption{spbmk} |spbmk|$=$\meta{string}
% \hfill\tcboxverb{Default: spb}\\
% |spbmk| is used to change the string associated to \enquote{soft}
% page breaks.\\
% \DescribeOption{hpbmk} |hpbmk|$=$\meta{string}
% \hfill\tcboxverb{Default: hpb}\\
% |hpbmk| is used to change the string associated to \enquote{hard}
% page breaks.
%
% As an example, what follows has \enquote{soft} page breaks printed
% in blue and \enquote{hard} page breaks printed in red:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\ekdsetup{
  showpagebreaks,
  spbmk = \textcolor{blue}{spb},
  hpbmk = \textcolor{red}{hpb}
}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \subsection{Using a Configuration File}
% \label{sec:using-conf-file}
% Complex editions may use a large number of witnesses, sources and
% scholars. It may also be required to define a multiple-layer
% apparatus criticus, several text environments to be aligned and
% quite a number of new commands. \pkg{ekdosis} provides a convenient
% way to avoid overloading the document preamble: all the settings
% related to the critical edition can be gathered in a separate
% configuration file named |\jobname-ekd.cfg|. If such a file can be
% found, its contents are automatically read and used by
% \pkg{ekdosis}.
%
% \subsection{Witnesses, Hands, Sources, Scholars \& Shorthands}
% \label{sec:declarations}
% \paragraph{Terminology}
% \label{sec:terminology}
% Strictly speaking, the term \enquote{witness} should apply to any
% manuscript evidence dating back to the Middle Ages used by the
% editor to establish the edition text. That said, editors often
% consult many other types of documents, such as modern editions,
% articles, notes, correspondence and the like, all of which fall into
% the category of \enquote{sources}. Furthermore, unpublished
% conjectures are also taken into account, not to mention the
% corrections and emendations that are proposed in many places by the
% editor of the text. As it is necessary to refer to scholars as
% individuals, \enquote{scholars} naturally emerges as a third
% category.
%
% Any reference that is to be used in the apparatus criticus must be
% \enquote{declared} in the preamble beforehand, namely: manuscript
% sigla (either for single manuscripts or manuscript families, primary
% or later hands, \emph{\&c.}), abbreviated last names of sources
% and scholars.  To that effect, \pkg{ekdosis} provides the following
% preamble-only commands:---
% 
% \paragraph{Witnesses}
% \DescribeMacro{\DeclareWitness} \cs{DeclareWitness}\marg{unique
% id}\marg{rendition}\marg{description}\oarg{options}
% \phts\label{ref:declarewitness}\\
% This command requires three mandatory arguments enclosed between
% curly braces used to specify consecutively:
% \begin{enumerate}
% \item The unique identifier of the witness to be used both in the
%   |.tex| source file and as an |xml:id| in the \texttt{TEI xml}
%   output if any.\footnote{See \vpageref{ref:xmlid} for more
%   information.}
% \item The rendition to be used in the printed apparatus criticus,
%   which also will be found within the |<sourceDesc>| element of the
%   \texttt{TEI} header where the description of the witness occurs,
%   within a |<abbr type="siglum">| element.
% \item A basic description of the manuscript to be found in a typical
%   printed Conspectus Siglorum, namely: the name of the manuscript
%   followed by its call number.
% \end{enumerate}
% Finally, the optional argument of \cs{DeclareWitness} accepts a
% comma-separated list of the following \enquote{name=value} arguments
% the first six of which are used to collect items of information to
% be found within the |<msIdentifer>| element in the \texttt{TEI}
% header:\footnote{See
% \url{https://tei-c.org/release/doc/tei-p5-doc/en/html/MS.html\#msid}
% for detailed information on these elements.}---\\
% \DescribeOption{settlement} |settlement|$=$\meta{name}: The name of
% a city or administrative unit.\\
% \DescribeOption{institution} |institution|$=$\meta{name}: The name
% of an institution such as a university or library.\\
% \DescribeOption{repository} |repository|$=$\meta{name}: The name of
% the repository within which the witness is stored.\\
% \DescribeOption{collection} |collection|$=$\meta{name}: The name of
% a collection of manuscripts.\\
% \DescribeOption{idno} |idno|$=$\meta{call \#}: Any form of call
% number.\\
% \DescribeOption{msName} |msName|$=$\meta{name}: The name commonly
% used for the witness.\\
% \DescribeOption{origDate} |origDate|$=$\meta{date}: Any form of date
% used to identify the date of origin for the witness.\\
% \DescribeOption{locus} |locus|$=$\meta{locus}\newfeature[v1.3]: The
% sequence of folio references where the edition text is found in the
% manuscript.
%
% \phts\label{ref:marcianus-b}
% To take here one example, a witness such as the \emph{Marcianus
% Graecus}~269, referred to as manuscript \enquote*{M} in the
% editions, which contains sixty treatises transmitted under the name
% of Hippocrates, could be declared as follows:\footnote{The locus
% specified refers to Hippocrates' \emph{Epidemics}, Book~6.}---
%
%\iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}

        settlement=Venice,
        institution=Marciana Library,
        msName=Marcianus Gr.,
        idno=269,
        origDate=s. X,
        locus=fol. 416\textsuperscript{v}–426\textsuperscript{v}]
\end{minted}
% \iffalse
%</example>
% \fi
%
% \paragraph{Hands} 
% \DescribeMacro{\DeclareHand} \cs{DeclareHand}\marg{unique
% id}\marg{base ms.}\marg{rendition}\oarg{note}\\
% This command requires three mandatory arguments enclosed between
% curly braces and one optional argument between square brackets used
% to specify consecutively:---
% \begin{enumerate}
% \item The unique identifier of the hand to be used both in the
% |.tex| source file and as an |xml:id| in the \texttt{TEI xml} output
% if any.\footnote{See \vpageref{ref:xmlid} for more information.}
% \item The unique identifier of the witness the hand is related
% to. Of course, this witness must have been declared beforehand.
% \item The rendition to be used in the printed apparatus criticus,
% which also will be found within the |<handNote>| element of the
% \texttt{TEI} header where the description of the hand occurs, within
% a |<abbr type="siglum">| element.
% \item Some further information about the hand.
% \end{enumerate}
%
% To continue the preceding example, here is how additions and
% corrections found in the \emph{Marcianus Gr.}~269 could be declared
% after this witness has been declared itself:---
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\DeclareHand{M1}{M}{M\textsuperscript{1}}[Emendatio scribae ipsius]
\DeclareHand{M2}{M}{M\textsuperscript{2}}[Manus posterior]
\end{minted}
% \iffalse
%</example>
% \fi
%
% As can be seen, values such as |M|, |M1| and |M2| in the |.tex|
% source file will be printed as \getsiglum{M}, \getsiglum{M1} and
% \getsiglum{M2} respectively. Not only the code gains legibility, but
% also flexibility for simply changing any declared rendition will
% update corresponding sigla throughout the entire edition.
%
% As a final example, here is how \pkg{ekdosis} would encode
% information as declared above for the \emph{Marcianus Gr.}~269
% should a \texttt{TEI} output be required:---
% \iffalse
%<*example>

% The \emph{Conspectus Siglorum} that is placed ahead of the edition

% which provides the list of sigla used in the apparatus,
% b)~\emph{Editiones uel Studia}, which provides references to
% sources, either published or unpublished, which contain conjectures
% used in the apparatus criticus. \cs{DeclareSource} takes two

% \item The rendition to be used in the printed apparatus criticus.
% \end{enumerate}
%
% \danger As \pkg{ekdosis} can include and use \texttt{TEI

% \item The unique identifier of the family to be used in the |.tex|
%   source file.
% \item The rendition to be used in the printed apparatus criticus.
% \item A comma-separated list of previously declared witnesses.
% \end{enumerate}
%
% As an example, the manuscripts of Caesar's \emph{Gallic War} are
% divided into two families: α, which includes mss.\ A, M, B, R, S, L
% and N, and β, which includes mss.\ T, f, U and l. Therefore,
% provided that all these witnesses have been already declared, here
% is how the two families α  and β could be
% declared:\footnote{These witnesses are used in the example
% provided below in \vref{lst:caesar-bg}.}---
% \phts\label{ref:caesar-bg-sigla}
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\DeclareShorthand{a}{α}{A,M,B,R,S,L,N}
\DeclareShorthand{b}{β}{T,f,U,l}
\end{minted}
% \iffalse
%</example>
% \fi
%
% Then, symbols |a| and |b| can be used in the |.tex| source file in
% place of manuscripts that belong to either family.
%
% That said, \cs{DeclareShorthand} is not meant to be restricted to
% declared witnesses. On the contrary, it also applies to any declared
% sources and scholars by means of \cs{DeclareSource} and
% \cs{DeclareScholar}. As an example, assuming that a self-reference
% to the person responsible for the edition has been set in the
% preamble, an associated shorthand can be defined like so:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}
\DeclareScholar{ego}{ego}[
     forename=John,
     surname=Smith,
     note=Main editor of the text]
\DeclareShorthand{egoscr}{\emph{scripsi}}{ego}+\label{ln:egoscr}+
\end{minted}
% \iffalse
%</example>
% \fi
%
% Then, the shorthand |egoscr| (l.~\lnref{ln:egoscr}) can be
% used to print in the apparatus criticus the technical term
% \emph{scripsi} and use at the same time the pointer |#ego| that is
% expected in the \texttt{TEI xml} output file. Detailed examples of
% this technique will be provided below in
% \vref{sec:emendations-conjectures}.
%
% \subsubsection{Printing Formatted Witnesses
% --- Conspectus Siglorum}
% \label{sec:print-witnesses}
% Once witnesses, hands, scholars and sources have been declared,
% \pkg{ekdosis} provides two commands to have them printed as declared
% from their identifiers.
%
% \DescribeMacro{\getsiglum} \cs{getsiglum}\marg{csv list of witnesses
% or single witness} behaves exactly as the |wit| optional argument of
% \cs{lem} and \cs{rdg} described below on pages~\pageref{ref:lem-wit}
% and \pageref{ref:rdg-wit}. From a single identifier or from a
% comma-separated list of identifiers, it returns their formatted
% counterparts. To return to the example provided
% \vpagerefrange{ref:marcianus-b}{ref:marcianus-e}, |\getsiglum{M}|
% would return \getsiglum{M}, while |\getsiglum{M1}| would return
% \getsiglum{M1}.
%
% \DescribeMacro{\SigLine} \cs{SigLine}\marg{unique id} returns from
% \meta{unique id} used in the first argument of
% \cs{DeclareWitness}\footnote{See above
% \vpageref{ref:declarewitness}.} a line ready to be inserted in a
% table set to print a Conspectus Siglorum with the following items of
% information separated by the symbol |&|: the siglum referring to the
% witness, the contents of the |description| field, followed if
% applicable by the sequence of folios that refers to the edition
% text, and the contents of the |origDate| field. An example of how
% one could print the Conspectus Siglorum of the manuscripts of
% Caesar's \emph{Gallic War} from the list provided
% \vpageref{ref:caesar-bg-sigla} follows:---

% \subsection{Editing a Single Text}
% \label{sec:single-text-editing}
% \DescribeEnv{ekdosis}
% Running paragraphs of one single text to be edited should be
% inserted in the \env{ekdosis} environment, like so:\footnote{See
% above \vref{lst:pj1}.}---
% \iffalse
%<*example>
% \fi

% \fi
% 
% \paragraph{Apparatus Entries}
% \DescribeMacro{\app} \cs{app}|[type=|\meta{type}|]|\marg{apparatus
% entries}\phts\label{ref:app-cmd}\\
% This command takes one mandatory argument and accepts one optional
% argument.  Once references to be used as witnesses in the apparatus
% criticus have been declared in the preamble as described in
% \ref{sec:declarations}
% \vpagerefrange{sec:declarations}{sec:declarations-end}, the \cs{app}
% command is used for inserting entries in the apparatus criticus,
% either lemmata, readings or notes, like so:---
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
I saw my friend \app{\lem{Peter}\rdg{John}} yesterday.
or:
I saw my friend
  \app{
    \lem{Peter}
    \rdg{John}
  }
yesterday.
\end{minted}
% \iffalse
%</example>
% \fi
% \cs{app} accepts one further optional argument:---\\
% \DescribeOption{type} |type|$=$\meta{type}\phts\label{ref:app-type}
% \hfill\tcboxverb{Default: default}\\
% As will be described below in \vref{sec:multilayer-apparatus},
% \pkg{ekdosis} initially sets one layer of notes\===the |default|
% layer\===in the apparatus criticus. This layer is fit to receive
% notes related to variant readings from witnesses and sources used by
% the editor to establish the edition text. Additional layers can be
% defined to receive other kinds of notes, such as references to texts
% quoted or cited in the text of the edition (\emph{apparatus
% fontium}), references to testimonia, or quotations of the edited
% text by other authors (\emph{apparatus testium}), explanatory notes,
% and so forth.\footnote{See below, \vref{ref:type-note}.} Once
% additional layers have been defined and assigned to new
% \enquote*{types}, such as \enquote*{testium} and the like, these
% types can be used as values appended to the |type| \enquote*{named
% option}. For more information about inserting notes in
% multiple-layer apparatus, see \vref{sec:notes-in-multilayer-app}.
%
% \mansee \pkg{ekdosis} also provides a two-argument \cs{App} command
% which is strictly equivalent to \cs{app} but allows for much more
% flexible code folding in the \textsf{emacs} text editor. Code
% folding may be needed when readings and critical notes grow in
% number to a point where the edition text becomes illegible. This
% command is described below in \vnref{sec:using-emacs}. (See
% \vpageref{ref:App-cmd}.)
%
% \paragraph{Base text and variants} As can be seen in \vref{lst:pj1}
% and the examples provided above, there are two kinds of individual
% readings: the \emph{lemma}, which contains the base text accepted by
% the editor, and the \emph{reading}, which contains deviant readings
% rejected by the editor.
%
% \danger What follows refers to the notions of \enquote{witness},
% \enquote{source} and \enquote{scholar} as defined above
% \vpageref{sec:terminology}.
%
% \paragraph{Lemmata} \phts\label{ref:lemmata}\DescribeMacro{\lem}
% \cs{lem}\oarg{options}\marg{lemma text}\\
% As \meta{lemma text} is a word or a phrase judged by the editor to
% be authentic or authoritative, \cs{lem} prints it by default both in
% the edition text and as the first part of a new entry in the
% apparatus criticus, preceded by the line number where it occurs or a
% broad space when the entry refers to the same line as the preceding
% entry. \phts\label{ref:lem-opts-b}The optional argument of \cs{lem}
% accepts the following comma-separated list of \enquote{name$=$value}
% arguments:---\\
% \DescribeOption{wit} |wit|$=$\meta{csv list of
% witnesses}\phts\label{ref:lem-wit}\\
% While a single witness may be recorded as in |wit=A|,
% comma-separated lists of multiple witnesses must obviously be
% enclosed in curly braces, like so:
% |wit={A,B,C}|. \phts\label{ref:mss-sep-families}It must be noted
% that witnesses can be grouped by using spaces as separators, like
% so: \verb*|wit={A,B,C, D,E,F}|. \danger In the apparatus criticus in
% print, it is customary to remind the reader of the manuscript
% groupings by spaces or commas. \pkg{ekdosis} prints spaces by
% default, but can be instructed to print any other symbol
% instead.\footnote{See below \vpageref{ref:familysep} for details.}
% \danger Although any unique identifiers or labels used to
% \enquote{declare} sources and scholars as described above
% \vpagerefrange{ref:declare-source}{ref:declare-scholar} can also be
% used as values of the |wit| optional argument, it is recommended to
% use |sources| and |resp| to refer to either category
% respectively as described below.\\
% \DescribeOption{source} |source|$=$\meta{csv list of
% sources}\phts\label{ref:lem-source}\newfeature[v1.1]\\
% A \enquote{source} refers to any type of document consulted by the
% editor to establish the edition text. Most commonly, corrections and
% emendations from previous editions are cited in the apparatus
% criticus.\footnote{For edition texts used as sources, see examples
% below in \vref{sec:emendations-conjectures} and
% \vref{sec:references-cited-works}.}\\
% \DescribeOption{resp} |resp|$=$\meta{csv list of
% scholars}\phts\label{ref:lem-resp}\newfeature[v1.1]\\
% |resp| refers to scholars responsible for the emendations,
% conjectures and corrections that are cited in the apparatus
% criticus.\footnote{See detailed examples in
% \vref{sec:emendations-conjectures}.}\\
% \DescribeOption{alt} |alt|$=$\meta{alternate lemma}\\
% While the mandatory argument of \cs{lem}, \meta{lemma text}, is
% always used to print the edition text in the upper part of the page,
% \meta{alternate lemma}, if specified, supersedes what is printed in
% the related entry of the apparatus criticus. This mechanism is
% useful in more than one respect. For instance, it can be used to
% insert abbreviated lemmata in the apparatus criticus, or to
% introduce an alternate way of writing entries with Latin technical
% terms in the apparatus criticus as will be demonstrated below in the
% example provided by \vref{lst:pj2}.\\
% \DescribeOption{ilabel}\phts\label{ref:ilabel-opt}
% |ilabel|$=$\meta{indexed label}\\
% \newfeature[v1.5] If used, |ilabel| instructs \pkg{ekdosis} not to
% set a label at the place where \meta{lemma text} ends. Instead, the
% label is indexed as \meta{indexed label} and only used to compute
% the ending line number at the place where the index is recalled by
% \cs{ilabel}\marg{indexed label}.\footnote{See below
% \vpageref{ref:ilabel-cmd}.} This allows for abbreviated lemmas
% corresponding to spans of texts that cross verse, paragraph or
% section boundaries as described below in \vnref{sec:lacunae}.\\
% \DescribeOption{nodelim} |nodelim|$=$\verb+true|false+\\
% \newfeature[v1.5] This named argument does not need a value as it
% defaults to |true| if used. |nodelim| removes the delimiter that is
% printed just before the entry in the apparatus criticus. This option
% is typically used in rare occasions in combination with |nolem| and
% |nonum| for entries that carry information not to be printed in the
% apparatus but nevertheless to be retained in the \texttt{TEI xml}
% output file.\\
% \DescribeOption{sep} |sep|$=$\meta{separator}\\
% |sep| allows to change the symbol used to separate the lemma text
% from deviant readings, which is by default the closing square
% bracket (|]|)\\
% \DescribeOption{nosep} |nosep|$=$\verb+true|false+\\
% This named argument does not need a value as it defaults to |true|
% if used. |nosep| removes the separator mentioned above. Obviously,
% |nosep| must be used when for some reason no \cs{rdg} command
% follows a \cs{lem} command that has just been used, as shown below
% in \vref{lst:emend-coni-corr},
% l.~\lnref{ln:emend:nosep}. \danger If |nosep| be used so as
% to insert an explanatory note after the lemma text with the
% \cs{note} command described below \vpageref{ref:editorial-notes},
% then the |sep| optional argument of \cs{note} can be used to put
% back in the separator. This technique is demonstrated below in
% \vref{lst:emend-coni-corr},
% ll.~\ekdelide{\lnref{ln:emend:sep:b}%^^A
% --\lnref{ln:emend:sep:e}}.\\
% \DescribeOption{nolem} |nolem|$=$\verb+true|false+\\
% This named argument does not need a value as it defaults to |true|
% if used. |nolem| completely removes the lemma text from the related
% entry in the apparatus criticus.\\
% \DescribeOption{Nolem} (no-value argument)\\
% \newfeature[v1.5] |Nolem| takes no value and is equivalent to
% |nodelim,| |nolem,| |nonum|. For an example of its usage, see
% \vnref{sec:lacunae} and \vref{lst:cic-att}.\\
% \DescribeOption{type} |type|$=$\meta{value}\\
% This named argument has no effect on the apparatus criticus of the
% edition in print, but it is used in the \texttt{TEI xml} output to
% classify the variation recorded in the entry according to some
% convenient typology. Categories such as lexical, morphological,
% orthographical and the like may apply. Obviously, |type=emendation|
% should be restricted to lemma texts and |type=conjecture| to variant
% readings recorded by means of \cs{rdg} described below.
% 
% \needspace{2\baselineskip}
% \noindent
% \DescribeOption{num} (no-value
% argument)\phts\label{ref:lem-num}\newfeature[v1.3]\\
% |num| takes no value. If used, this argument instructs to print any
% line number that \pkg{ekdosis} may have decided not to print in the
% apparatus criticus before the lemma text.\\
% \DescribeOption{nonum} (no-value
% argument)\phts\label{ref:lem-nonum}\newfeature[v1.3]\\
% Compared to |num|, |nonum| does the opposite. If used, any number
% that \pkg{ekdosis} may have decided to print before the lemma text
% is suppressed.
%
% \needspace{11\baselineskip}
% Finally, four named arguments can be used to insert words at the
% following specific places in the lemma text:\\
% \noindent
% \fparbox*{\centered{\textbf{1} \tikzmark{pre}\tred{pre} Peter
% \tikzmark{post}\tred{post} \tikzmark{prewit}\tred{prewit}
% \getsiglum{pjA}
% \tikzmark{postwit}\tred{postwit}] John \getsiglum{pjB}}}\\
% \DescribeOption{pre} |pre|$=$\meta{words}\pointtol{pre}\\
% |pre| inserts \meta{words} \emph{before} the lemma text.\\
% \DescribeOption{post} |post|$=$\meta{words}\pointto{post}\\
% |post| inserts \meta{words} \emph{after} the lemma text.\\
% \DescribeOption{prewit} |prewit|$=$\meta{words}\pointto{prewit}\\
% |prewit| inserts \meta{words} \emph{before} the list of witnesses.\\
% \DescribeOption{postwit} |postwit|$=$\meta{words}\pointtor{postwit}\\
% |postwit| inserts \meta{words} \emph{after} the list of witnesses.
% \phts\label{ref:lem-opts-e}
%
% \paragraph{Readings} \DescribeMacro{\rdg}
% \cs{rdg}\oarg{options}\marg{variant reading}\\
% As \meta{reading} is a word or a phrase judged by the editor to be
% unsatisfactory or corrupted, \cs{rdg} prints it by default in the
% last part of the corresponding entry in the apparatus criticus,
% after the symbol that is used to separate words of the base text
% (the lemma text) from words rejected by the editor.  The optional
% argument of \cs{rdg} accepts a comma-separated list of
% \enquote{name$=$value} arguments that is almost identical to
% \cs{app}. Therefore, emphasis will be placed here only on the
% differences. The reader is invited to refer to the description
% provided above \vpagerefrange{ref:lem-opts-b}{ref:lem-opts-e} for
% more detailed information:---\\
% \DescribeOption{wit} |wit|$=$\meta{csv list of
% witnesses}\phts\label{ref:rdg-wit}\\
% \DescribeOption{source} |source|$=$\meta{csv list of sources}\\
% \DescribeOption{resp} |resp|$=$\meta{csv list of scholars}\\
% \DescribeOption{alt} |alt|$=$\meta{alternate reading}\\
% \DescribeOption{nordg} |nordg|$=$\verb+true|false+\\
% This named argument does not need a value as it defaults to |true|
% if used. |nordg| completely removes the variant reading from
% the related entry in the apparatus criticus.\\
% \DescribeOption{type} |type|$=$\meta{value}\\
% Obviously, |type=conjecture| should be restricted to variant
% readings and |type=emendation| to lemma texts recorded by means of
% \cs{lem} described above.\\
% \DescribeOption{pre} |pre|$=$\meta{words}\\
% \DescribeOption{post} |post|$=$\meta{words}\\
% \DescribeOption{prewit} |prewit|$=$\meta{words}\\
% \DescribeOption{postwit} |postwit|$=$\meta{words}\\
% \DescribeOption{subsep} |subsep|$=$\meta{subseparator}\\
% \newfeature[v1.4] |subsep| inserts a subseparator to be printed
% \emph{before} the current entry as described below
% \vpageref{ref:setsubseparator}. This option is supposed to be used
% when no subseparator is defined, or when one is defined but for some
% reason a different subseparator is needed for the current
% entry.\\
% \DescribeOption{nosubsep} This argument-less option removes the
% subseparator from the current entry, provided one has been set by
% means of \cs{SetSubseparator}, \cs{SetApparatus} or
% \cs{DeclareApparatus}.\footnote{See
% \vpagerefrange{ref:setsubseparator}{ref:apparatus-settings-e} and
% \vref{sec:declaring-layers} for details.}
%
% \paragraph{Notes}
% \DescribeMacro{\note}\phts\label{ref:notes-b}\DescribeMacro{\note*}
% \cs{note}\oarg{options}\marg{text} or
% \cs{note*}\oarg{options}\marg{text}\phts\label{ref:editorial-notes}\\
% It may happen that editorial notes are needed to record short
% comments of general nature \emph{between} lemmata and
% readings. \cs{note} inserts inline comments while \cs{note*} places
% comments below the entire apparatus block. Furthermore, if
% \pkg{ekdosis} be loaded with the |parnotes| option as described
% above \vpageref{ref:parnotes-opt}, \cs{note*} will use the
% \pkg{parnotes} package to lay out the notes as an additional
% paragraph below the apparatus criticus. The optional argument of
% \cs{note}/\cs{note*} accepts the following comma-separated list of
% \enquote{name$=$value}
% arguments:---\\
% \DescribeOption{pre} |pre|$=$\meta{words}\\
% |pre| inserts \meta{words} immediately before the note.\\
% \DescribeOption{post} |post|$=$\meta{words}\\
% |post| inserts \meta{words} immediately after the note.\\
% \DescribeOption{sep} This argument-less option is equivalent to
% |post=\ekdsep|.\footnote{See below
%  \vpageref{ref:ekdsep-subsep} for more information and
%  \vref{lst:emend-coni-corr}, ll.~%^^A
%  \ekdelide{\lnref{ln:emend:sep:b}--\lnref{ln:emend:sep:e}}
%  for an illustrative example.}\saveFN\fnEmend\\
% \DescribeOption{subsep} This argument-less option is equivalent to
% |pre=\ekdsubsep|.\useFN\fnEmend\\
%
% \danger Under no circumstances is it permitted to insert this
% command \cs{note} or \cs{note*} inside the argument of \cs{lem} or
% \cs{rdg}. \cs{note}/\cs{note*} must go \emph{between} these
% commands. As a general rule, within \cs{app}|{}| elements, notes are
% inserted immediately \emph{after} the lemma or the variant reading
% they are related to. However, as will be described below in
% \vref{ref:type-note}, the command \cs{note}\---with no star
% appended\---that is used to insert explanatory notes or references
% to sources or testimonia is permitted within the mandatory argument
% of \cs{lem}|{}|, although it is subject to a very strict syntax.

% \item Close examination of lines~\ekdelide{%^^A
%   \lnref{ln:pj2:alt:b}--\lnref{ln:pj2:alt:e}} from
%   \vref{lst:pj2} shows how |alt| has been used to insert an abridged

% \item The same technique has been used at
%   line~\lnref{ln:pj2:alt2} to insert alternate words,
%   including Latin technical terms, in place of the variant
%   reading. Hence the use of |nolem| at
%   line~\lnref{ln:pj2:nolem} to remove the lemma text from the
%   apparatus criticus in print.
% \item \cs{note*} has been used to insert short annotations in two

% \subsection{Indicating Subvariation in Apparatus Entries}
% \label{sec:indic-subv-appar}
% It must be noted that grouping readings so as to keep emphasis on
% subvariation, regardless of its cause, is entirely optional.
% Furthermore, the applicability of this technique is limited to the
% \texttt{TEI xml} output as it helps the machines to understand a
% grouping otherwise immediately accessible to human mind from the
% information that is available in well-written
% apparatus. \pkg{ekdosis} provides two ways of expressing
% subvariation.
%
% \subsubsection{Implicit Grouping}
% \label{sec:implicit-grouping}
% Because apparatus entries may nest recursively, the \cs{app} command
% can be used to group similar readings.
%
% \danger However, for nesting to work, the |alt| optional argument
% must be used in every \cs{lem} and \cs{rdg} command involved in the
% nesting. This rule applies to both parent and child commands, as
% demonstrated in the following example:---
% 
% \iffalse

% 
% \begin{remarks}

%
% \danger It must be noted that from a technical standpoint, albeit
% the nested lemmas are printed \emph{before} their parents in the
% apparatus criticus, they are seen by \pkg{ekdosis} \emph{after} the
% latter as the source file is compiled. As a result, notably when the
% whole nested group of lemmas falls on the same line without being
% preceded by an apparatus entry on this line, it may be needed to
% suppress redundant numbers that \pkg{ekdosis} may have decided to
% print in the appartus criticus. Conversely, it may be needed to
% print numbers that \pkg{ekdosis} may have decided not to print. To
% both ends, the |num| and |nonum| optional arguments of the \cs{lem}
% command can be used as described above
% \vpagerefrange{ref:lem-num}{ref:lem-nonum}.

% \subsubsection{Explicit Grouping}
% \label{sec:explicit-grouping}
% \DescribeMacro{\rdgGrp} \cs{rdgGrp}\oarg{options}\marg{lemma text
% \textbar\ readings}\newfeature[v1.1]\\
% Explicit grouping of readings can be achieved by means of the
% \cs{rdgGrp} command. It takes as mandatory argument the commands
% used for inserting lemma texts, readings and notes that are
% described \vpagerefrange{ref:lemmata}{ref:notes-e}, viz.\ \cs{lem},
% \cs{rdg} and \cs{note}. \cs{rdgGrp} accepts one further optional
% argument:---\\
% \DescribeOption{type} |type|$=$\meta{value}\\
% This named argument is used in the \texttt{TEI xml} output to
% define an attribute common to all elements representing the

% \section{Emendations and Conjectures}
% \label{sec:emendations-conjectures}
% From a technical standpoint, \enquote{conjectures} are readings that
% are not supported by manuscript evidence, but are instead proposed
% by scholars to be taken into consideration for establishing the
% edition text. A conjecture is called an \enquote{emendation} when it
% is adopted in place of what is provided by or missing from the text
% provided by the manuscripts. Emendations and conjectures are
% therefore readings and as such expected to be found within |<lem>|
% or |<rdg>| elements. However, as both come from editions or
% scholars, not from manuscripts, they are naturally associated with
% |source| or |resp| attributes as described above
% \vpagerefrange{ref:lem-source}{ref:lem-resp},\footnote{See also
% \vpagerefrange{ref:declare-source}{ref:declare-scholar}.} and can be
% distinguished from one another by the |type| attribute, eg.\ either
% |emendation| or |conjecture|.
%
% As an example, the representation of witnesses, editors and
% shorthands of Hippocrates' \emph{Epidemics}, Book~2 could be
% summarized as follows:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}

% \iffalse

% \fi
%
% As can be seen from lines~\ekdelide{%^^A
% \lnref{ln:wsc:short1}--\lnref{ln:wsc:short2}},
% three useful shorthands have been defined: |codd| prints
% \enquote{codd.} for Latin pl.\ \emph{codices} viz.\ \enquote{all
% manuscripts} and refers to the three \texttt{xml} identifiers |V|,
% |I|, |R| and |H| declared at
% ll.~\ekdelide{%^^A
% \lnref{ln:wsc:wit1}--\lnref{ln:wsc:wit2}} and
% \ekdelide{\lnref{ln:wsc:wit3}--\lnref{ln:wsc:wit4}};
% |edd| prints \enquote{edd.} for Latin pl.\ \emph{editores} viz.\
% \enquote{all editors} and refers to the three \texttt{xml}
% identifiers |Lit|, |Erm| and |Sm| declared at
% ll.~\ekdelide{%^^A
% \lnref{ln:wsc:src1}--\lnref{ln:wsc:src2}};%^^A
% \footnote{For detailed information on how to use \cs{DeclareSource}
% and insert references to cited works, the reader is invited to refer
% to \vref{sec:references-cited-works}.} finally, |egoscr|
% (l.~\lnref{ln:wsc:short2}) is used to print the technical
% Latin term \enquote{\emph{scripsi}}, \enquote{I wrote}, to denote a
% personal conjecture. Then, the |.tex| source file can be structured
% as follows:---

% \subsection{Editorial Addition and Deletion}
% \label{sec:editorial-add-del}
% \pkg{ekdosis} provides a set of commands to indicate that text has
% been supplied or removed by conjecture. As regards critical
% symbols conventionally used for representing emendations, lacunae,
% omissions, gaps, editorial deletions or additions and the like,
% \pkg{ekdosis} follows the standards as described by
% \textcite[80--82]{West1973}:---
% \begin{description}[font=\ttfamily]
% \item[<>] text added by conjecture or from a parallel source.
% \item[***] lacuna in the whole textual tradition.
% \item[<***>] conjectured lacuna.
% \item[\{\}] editorial deletion.
% \item[\dag\dag] text judged by the editor to be corrupt. Note that if
% only one word be suspect, only one crux is needed. 
% \end{description}
%
% \DescribeMacro{\SetCritSymbols}\newfeature[v1.1]
% \cs{SetCritSymbols}\marg{csv list of options} can be used to change
% the critical symbols described above. This command accepts the
% following list of |key-value|
% optional arguments:---\\
% \DescribeOption{suppbegin}|suppbegin|$=$\meta{symbol}
% \hfill\tcboxverb{Default: <}\\
% The opening symbol used to mark the text that is supplied.\\
% \DescribeOption{suppend}|suppend|$=$\meta{symbol}
% \hfill\tcboxverb{Default: >}\\
% The closing symbol used to mark the text that is supplied.\\
% \DescribeOption{delbegin}|delbegin|$=$\meta{symbol}
% \hfill\tcboxverb|Default: {|\\
% The opening symbol used to mark the text that is deleted.\\
% \DescribeOption{delend}|delend|$=$\meta{symbol}
% \hfill\tcboxverb|Default: }|\\
% The closing symbol used to mark the text that is deleted.\\
% \DescribeOption{sicbegin}|sicbegin|$=$\meta{symbol}
% \hfill\tcboxverb{Default: †}\\
% The opening symbol used to mark the text that is deemed to be
% suspect.\\
% \DescribeOption{sicend}|sicend|$=$\meta{symbol}
% \hfill\tcboxverb{Default: †}\\
% The closing symbol used to mark the text that is deemed to be
% suspect.\\
% \DescribeOption{gapmark}|gapmark|$=$\meta{symbols}
% \hfill\tcboxverb{Default: ***}\\
% The symbols used to mark lacunae.\\
% \DescribeOption{keepinapp} |keepinapp|$=$\verb+true|false+
% \hfill\tcboxverb{Default: false}\\
% \newfeature[v1.4] This named argument does not need a value as it
% defaults to |true| if used. By default, the critical symbols used by
% \cs{supplied}, \cs{surplus} and \cs{sic} described below
% \vpagerefrange{ref:corr-cmds-b}{ref:corr-cmds-e} are printed in the
% edition text but removed from the apparatus. |keepinapp| instructs
% \pkg{ekdosis} to print these symbols in both places.
%
% As an example, what follows sets |[]| for deletions and |...| for
% lacunae:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\SetCritSymbols{
  delbegin = [,
  delend = ],
  gapmark = \dots
}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \danger If modified, brackets can be adapted to languages that are
% written from right to left. To that effect, \pkg{ekdosis} provides a
% boolean expression |al@rlmode| which is evaluated as |true| if the
% writing direction be set from right to left and as |false|
% otherwise. As the \pkg{etoolbox} package is loaded by \pkg{ekdosis},
% \cs{ifboolean}|{al@rlmode}|\marg{rtl symbol}\marg{ltr symbol} can be
% used to perform the test.
%
% \paragraph{Editorial Addition}
% \phts\label{ref:corr-cmds-b}
% \DescribeMacro{\supplied}\newfeature[v1.1]\cs{supplied}\marg{text}
% is used to mark \meta{text} that is by definition missing from the
% tradition as supplied by the editor or some other scholar. This
% command is normally expected in \cs{lem}|{}| or \cs{rdg}|{}|.
%
% \paragraph{Editorial Deletion}
% \DescribeMacro{\surplus}\newfeature[v1.1] \cs{surplus}\marg{text}
% is used to mark \meta{text} that is deemed to be inauthentic, but
% nevertheless retained between braces in the edition text as it is
% transmitted by all witnesses. This command is normally expected in
% \cs{lem}|{}| or \cs{rdg}|{}|.
%
% \paragraph{Crux}
% \DescribeMacro{\sic}\newfeature[v1.1] \cs{sic}\marg{text} takes as
% mandatory argument the text deemed by the editor to be readable but
% not understandable. \cs{sic} inserts \meta{text} between cruces
% while \cs{sic*} prints only one crux before \meta{text}.
% \phts\label{ref:corr-cmds-e}
%
% \paragraph{Lacuna}
% \DescribeMacro{\gap}\newfeature[v1.1] \cs{gap}\marg{csv list of
% options} indicates that some amount of text has fallen away from the
% entire tradition. It takes as mandatory argument a comma-separated
% list of options that can be used to further specify the reason for
% omission, the unit of measurement, the quantity or the extent, as
% follows:---\\
% \DescribeOption{reason}|reason|$=$\meta{reason}\\
% |reason| gives the reason for omission.\\
% \DescribeOption{unit} |unit|$=$\meta{unit}\\
% |unit| provides some regularized measurement, such as |character|,
% |word|, |line| and the like.
% \DescribeOption{quantity} |quantity|$=$\meta{n}\\
% |quantity| specifies the number of the given unit that comprise the
% measurement.\\
% \DescribeOption{extent} |extent|$=$\meta{description}\\
% |extent| describes the size, including quantity and unit in a single
% string of words.
%
% \paragraph{Conjectured Lacuna}
% Assumably, the conjectured lacuna should be enclosed by
% \cs{supplied} and as such contained by \cs{lem} with
% |type=emendation| to indicate that the lacuna has been accepted by
% the editor.
%
% Examples follow:\footnote{On the use of \texttt{egomute}

% \section[Lacunae]{\newfeature[v1.5]Lacunae}
% \label{sec:lacunae}
% The term \enquote{lacuna} is used here to indicate a series of words
% or phrases that are missing from one or more witnesses in the
% manuscript tradition. When the lacuna is limited to just a few
% words, it may fill an entire entry of the apparatus criticus,
% especially when the other witnesses do not provide variants on this
% span of text.
%
% On the other hand, when the lacuna is longer, or includes variants,
% or crosses a verse, paragraph or section boundary, it is usually not
% desirable to break it into pieces. The recommended method of
% encoding is therefore to record explicitly where the lacuna begins
% and where it ends. However, in well-written apparatus criticus,
% these two items of information must be provided only in the first
% entry. Moreover, the line numbering of this entry and the
% abbreviated lemma must make clear where the lacuna ends. As a
% consequence, the apparatus in print is silent at the place where the
% lacuna ends, unlike the \texttt{TEI xml} code which must be explicit
% at both places.
%
% \DescribeMacro{\lacunaStart}\DescribeMacro{\lacunaEnd}
% \cs{lacunaStart}\oarg{opt} and \cs{lacunaEnd}\oarg{opt} are used in
% the mandatory argument of the \cs{rdg} command to indicate the
% beginning and the end of the lacuna. The optional argument of these
% commands can be used to specify which witnesses are affected by the
% lacuna, as follows:---\\
% \DescribeOption{wit} |wit|$=$\meta{csv list of witnesses}\\
% This option is described above \vpageref{ref:lem-wit}. Of course, it
% is unnecessary to use it in the case where only one witness in
% involved in the variant reading that supply the information on the
% lacuna.
%
% \DescribeMacro{\ilabel} \phts\label{ref:ilabel-cmd}
% \cs{ilabel}\marg{indexed label} is used to recall the indexed label
% set by means of the |ilabel| optional argument of the \cs{lem}
% command as described above \vpageref{ref:ilabel-opt}. This command
% is used to compute the line number where the lacuna ends and must be
% inserted precisely at this place, supposedly outside the group
% formed by the \cs{app} command used to print the information on the
% lacuna in the apparatus criticus.
%
% This technique is demonstrated by the following example taken from
% Cicero's \emph{Letters to Atticus}, VII,
% 9.4:\footnote{\cite[121.13--15]{CiceroAtt}. English translation:
% \cite[51]{CiceroAttTr}.}---

% \begin{remarks}
% \item At line~\lnref{ln:lac:ilabel:opt}, from the |ilabel| optional
%   argument, \pkg{ekdosis} knows that the span of text affected by
%   the lacuna does not end after \emph{sed}, but after \emph{legis}
%   (l.~\lnref{ln:lac:ilabel:cmd}), at the place where the indexed label
%   is recalled by \cs{ilabel}. So line numbers are computed
%   accordingly in the apparatus criticus.
% \item The starting and ending points of the lacuna from which the
%   \sg{Ω} family suffers have been marked by \cs{lacunaStart} and
%   \cs{lacunaEnd} respectively (ll.~\lnref{ln:lac:lstart} and
%   \lnref{ln:lac:lend}).
% \item Line~\lnref{ln:lac:lend} shows that \emph{legis}
%   (l.~\lnref{ln:lac:ilabel:cmd}) does not appear in the \sg{Ω}
%   family. This is where the lacuna ends. Furthermore, as no other
%   witnesses are mentioned in the \cs{rdg} command
%   (l.~\lnref{ln:lac:lend}), using the |wit| optional argument of
%   \cs{lacunaEnd} would introduce an unnecessary redundancy.

% \section{Alignment of Parallel Texts}
% \label{sec:alignment-basic}
% As already said above,\footnote{See point
% \vref{it:multicol-feature}.} \pkg{ekdosis} can arrange sundry texts
% in parallel columns\---synchronized or not\---either on the same
% page or on facing pages. Depending on what is needed, any text can
% be equipped with an apparatus criticus. The most common example is
% that of an edition of a classical text with an apparatus criticus
% accompanied by a translation into a modern language on the facing
% page. One can also imagine an edition of two classical texts or two
% different recensions of the same text, each of which provides
% variants recorded in separate apparatus criticus, laid out on the
% left-hand pages, with one or more translations on the corresponding
% right-hand pages, and so forth.
%
% \paragraph{The \env{alignment} Environment}
% \DescribeEnv{alignment} \cs{begin}|{alignment}|\oarg{options}\dots
% \cs{end}|{alignment}|\phts\label{ref:alignment-syntax}\\
% This environment can be used as it is provided to typeset a standard
% critical edition, namely an edition text, equipped with an apparatus
% criticus and laid out on the left-hand pages, accompanied by a
% translation into a modern language on the facing pages.
%
% \DescribeEnv{edition}\DescribeEnv{translation} Within
% \env{alignment}, two environments are available by default:
% \cs{begin}|{edition}|\allowbreak\dots
% \cs{end}|{ed|\allowbreak|ition}| and \cs{begin}|{translation}|\dots
% \cs{end}|{translation}|. Obviously, the former is used to typeset
% the edition text with an apparatus criticus on the left, while the
% latter is used to typeset the translation on the right, like so:---
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}

    Second § of the edition text.
  \end{edition}

\end{alignment}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \DescribeEnv{edition*}
% \DescribeEnv{translation*}
% \phts\label{ref:starred-envs} Furthermore, so-called
% \enquote{starred} versions of these environments can be used at any
% point to synchronize texts, that is to print them in such a way that
% the tops of all paragraphs are vertically aligned. To that effect,
% it must be noted that merely applying this command on a single
% environment\---for instance the leftmost one\---will have all other
% associated paragraphs printed aligned.
%
% \danger While the whole edition text and the whole translation can
% be inserted in a single \env{edition}/\env{translation} environment
% respectively, it is recommended to enter both texts paragraph by
% paragraph as shown in the example above. Not only this method of
% encoding allows not to lose sight of paragraphs that are meant to be
% read together, but it is also the only way to align paragraphs in
% print, and it is much more suitable to mark up correspondence
% between spans of texts.
%
% As an illustration, a short extract of Caesar's \emph{Gallic War},
% VI, XIII.1 follows.\footnote{Latin text: \cite{Caesar-BG-v2};
% English translation: \cite{CaesarTr}.} See the list of sigla for
% manuscripts and manuscript families above
% \vpageref{ref:caesar-bg-sigla}. As this document is not set for
% duplex printing, both texts have been put together on the same

%   \vref{lst:caesar-bg}, ll.~9--10. But as this variant is already

%   remove the entire otherwise redundant variant from the apparatus
%   criticus in print. Hence the use of |nordg| at l.~11.
% \item For examples of abbreviations, see ll.~6 and 17.
% \item Line~17 shows how mss.\ T and U (which belong to two distinct

% \subsection{Alignment of Several Texts}
% \label{sec:multiple-alignment}
% As described above \vpageref{ref:alignment-syntax}, the
% \env{alignment} environment may receive an optional argument in
% which
% the following \enquote{name$=$value} arguments are accepted:---\\
% \DescribeOption{tcols}
% |tcols|$=$\meta{number}\hfill\tcboxverb{Default: 2}\\
% |tcols| stores the \underLine{t}otal number of
% \underLine{col}umn\underLine{s} of text to be aligned.\\
% \DescribeOption{lcols}
% |lcols|$=$\meta{number}\hfill\tcboxverb{Default: 1}\\
% |lcols| stores the number of \underLine{col}umn\underLine{s} to be
% printed on the \underLine{l}eft-hand page, \emph{out of the total
% number} of columns specified with |tcols|. As can be seen from the
% preceding two default values, \env{alignment} initially sets two
% columns of text on facing pages. Of course, for this setting to work
% properly, one must ensure that the \env{alignment} environment is
% started on a
% left page.\\
% \DescribeOption{texts}
% |texts|$=$\meta{\underLine{semicolon}-separated
% values}\hfill\tcboxverb{Default: edition;translation}\\
% Depending on the total number of columns that has been specified
% with |tcols| above, |texts| is then used to define the names of the
% environments that shall receive edition texts, translations,
% \emph{\&c.} Furthermore, as described \vpageref{ref:starred-envs},
% \pkg{ekdosis} also defines \enquote{starred} versions of these
% environments to be used to synchronize columns so that corresponding
% paragraphs are printed vertically aligned. Some very important
% points need to be emphasized in this respect:---
% \begin{enumerate}
% \item Only unaccented letters of the alphabet (whatever the case)
%   are allowed to compose the names of \LaTeX{} environments.
% \item These names must be separated from one another by
%   \emph{semicolons}, as shown in red in the listing below at the end
%   of lines~1 and 2.
%   \begin{enumerate}
%   \item[\dbend] The comma at the end of line~3 closes the whole
%     value of |text| and acts as a higher level separator.
%   \end{enumerate}
% \item \phts\label{it:lang-subopt} Each name may be followed by a
%   \enquote*{suboptional} argument between square brackets which will
%   then be used to insert \texttt{TEI xml} attributes in the
%   corresponding |<div>| element. For example, \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}
texts=latin[xml:lang="la"]+\textcolor{red}{;}+
      english[xml:lang="en"]+\textcolor{red}{;}+
      french[xml:lang="fr"]+\textcolor{red}{,}+
\end{minted}
% \iffalse

...
</div>
\end{minted}
% \iffalse
%</example>
% \fi
%   \begin{enumerate}
%   \item[\dbend] As can be seen, \pkg{ekdosis} takes care of
%     computing and inserting the |xml:id| attributes which are
%     therefore not accepted in the \enquote*{suboptional} arguments
%     of |texts|.
%   \end{enumerate}
% \item The names of the environments must be specified in exactly the
%   same order as they are supposed to appear in the print edition,
%   from left to right.
% \end{enumerate}
% \DescribeOption{apparatus}
% |apparatus|$=$\meta{\underLine{semicolon}-separated
% values}\hfill\tcboxverb{Default: edition}\\
% Then, the |apparatus| option, just as |texts|, takes a
% \underLine{semicolon}-separated list of previously defined
% environments that shall receive at least one layer of apparatus
% criticus.\\
% \DescribeOption{paired} |paired|$=$\verb+true|false+%^^A
% \phts\label{ref:paired-opt}%^^A
% \hfill\tcboxverb{Default: true (initially not set)}\\
% This named argument does not need a value as it defaults to |true|
% if used. By default, \pkg{ekdosis} follows the \LaTeX{} page
% numbering scheme when multiple texts are arranged on facing
% pages. The |paired| option leaves every right-hand page number
% unchanged, so that both facing pages hold the same page
% number.\footnote{For setting headers and footers in this arrangement
% of text, but also for the current limitations attached to this
% option, see \vpageref{sec:header-paired-pages}.}\\
% \DescribeOption{lineation} |lineation|$=$\verb+page|document+
% \hfill\tcboxverb{Default: document}\\
% This option applies to edition texts initially set to receive an
% apparatus criticus. By default, lines are continuously numbered
% throughout the document. |lineation=page| sets the numbering to
% start afresh at the top of each page.\\
% \DescribeOption{flush} |flush|$=$\verb+true|false+
% \hfill\tcboxverb{Default: false}\\
% This named argument does not need a value as it defaults to |true|
% if used. This option applies when two or more distinct
% \env{alignment} environments are started on the same page. Should
% this happen, any subsequent \env{alignment} environment must be set
% with the |flush| option so that every one of them carry its own
% apparatus criticus.
%
% As an example, the alignment of the Latin edition text of Caesar's

% As \pkg{ekdosis} uses the \pkg{paracol} package for the layout of
% parallel texts, most of the commands provided by this package
% apply. In this respect, quite useful are the commands described in
% sections 7.3 to 7.6 on pp.~15--21 of the documentation of this
% package.\footcite{paracol}
%
% \danger It must be noted that all these commands are to be inserted
% \emph{before} the \env{alignment} environments on which they are
% supposed to operate.
%
% \subsubsection{Columns and Gutters}
% \label{sec:columns-gutters}
% 
% \paragraph{Column Ratio on Single Pages}
% \DescribeMacro{\columnratio}
% \cs{columnratio}\marg{r\textsubscript{1}, r\textsubscript{2}, \dots\
% , r\textsubscript{n}}, where \emph{r\textsubscript{1}} refers to the
% leftmost column, can be used to set the ratio of the columns in
% relation to each other.  Depending on the total number of columns on
% which one wishes to operate, a comma-separated list of decimal
% numbers is expected. As an example, \cs{columnratio}|{0.6}| will
% instruct \pkg{ekdosis} to have the first column spread over 60~\% of
% the total width of the text block, minus the total width of
% intercolumnar gutters.
%
% \paragraph{Column Ratio on Facing Pages}
% \cs{columnratio} accepts an optional argument which can be used as
% described above to set the ratio of columns to be printed on
% right-hand pages, like so: \cs{columnratio}\marg{r\textsubscript{1},
% r\textsubscript{2}, \dots\ ,
% r\textsubscript{n}}\oarg{r\textsubscript{1}, r\textsubscript{2},
% \dots\ , r\textsubscript{n}}.
%
% \paragraph{Column Width on Single Pages}
% \DescribeMacro{\setcolumnwidth}
% \cs{setcolumnwidth}\marg{w\textsubscript{1}, w\textsubscript{2},
% \dots\ , w\textsubscript{n}} operates the same way as
% \cs{columnratio} described above, except that dimensions are
% expected instead of ratios. As an example,
% \cs{setcolumnwidth}|{1in}| will have the width of the first column
% set to \unit[1]{in}.
%
% \paragraph{Gutter Width}
% Each value accepted by \cs{setcolumnwidth} can be expressed as a
% pair as in
% \cs{setcolumnwidth}\marg{w\textsubscript{1}/g\textsubscript{1},
% w\textsubscript{2}/g\textsubscript{2}, \dots\ ,
% w\textsubscript{n}/g\textsubscript{n}} where the character |/| acts
% as a separator, in which case \emph{g\textsubscript{x}} is used to
% set the width of the gutter that follows the
% \emph{x}\textsuperscript{th} column. As an example,
% \cs{setcolumnwidth}|{1in/0.25in}| will print a
% \unit[1]{in} first column, followed by a \unit[0.25]{in} gutter.
%
% \paragraph{Automatically Computed Values}
% Widths of columns and widths of gutters can be replaced with
% \cs{fill} and \cs{columnsep} respectively. As an example,
% \cs{setcolumnwidth}|{\fill/0.25|\allowbreak|in}| will only operate
% on the width that follows the first column, all remaining values
% being computed automatically.
%
% \paragraph{Column and Gutter Width on Facing Pages}
% Just like \cs{columnratio}, \cs{setcolumnwidth} accepts an optional
% argument which can be used to set the width of columns and gutters
% to be printed on right-hand pages, like so:
% \cs{setcolumnwidth}\marg{w\textsubscript{1}, w\textsubscript{2},
% \dots\ , w\textsubscript{n}}\oarg{w\textsubscript{1},
% w\textsubscript{2}, \dots\ , w\textsubscript{n}} for columns only,
% and \cs{setcolumnwidth}\marg{w\textsubscript{1}/g\textsubscript{1},
% w\textsubscript{2}/g\textsubscript{2}, \dots\ ,
% w\textsubscript{n}/g\textsubscript{n}}%
% \oarg{w\textsubscript{1}/g\textsubscript{1},
% w\textsubscript{2}/g\textsubscript{2}, \dots\ ,
% w\textsubscript{n}/g\textsubscript{n}} for columns and gutters.
%
% \paragraph{Vertical Rules}
% Vertical rules between columns can be drawn by setting the length of
% the \LaTeX\ \cs{columnseprule} register to a non-zero value, like
% so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\setlength{\columnseprule}{0.4pt}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \subsubsection{Marginal Notes}
% \label{sec:marginal-notes}
% By default, marginal notes that refer to the first column are
% printed in the left margin, while notes that refer to subsequent
% columns are printed in the right margin.
%
% \DescribeMacro{\marginparthreshold} \cs{marginparthreshold}\marg{n},
% where \emph{n} is an integer, can be used to change the default
% settings. This command instructs \pkg{ekdosis} that columns of text,
% up to the \emph{n}\textsuperscript{th} column included, shall have
% their marginal notes printed to the left. As a result, to take an
% example, \cs{marginparthreshold}|{0}| will have all marginal notes
% printed in the right margin. \cs{marginparthreshold} also accepts an
% optional argument, namely
% \cs{marginparthreshold}\allowbreak\marg{n}\oarg{n'}, that can be
% used to set the threshold for columns printed in right-hand pages.
%
% \subsubsection{Regular Footnotes}
% \label{sec:regular-footnotes}
% \DescribeMacro{\footnotelayout} By default, regular footnotes are
% printed at the bottom of the column on which they are
% called. \cs{footnotelayout}\marg{key-letter} can be used to change
% this setting. This command accepts as mandatory argument a
% key-letter which can be either |c|, |p| or |m|. |c| means
% \emph{column-wise} footnotes, which is the default value. |p| means
% \emph{page-wise}: footnotes from all columns are gathered in a
% single spanning block at the bottom of the page. Finally, |m| stands
% for \emph{merge}, which means that all footnotes that are called on
% a given page, including notes that are called outside the
% \env{alignment} environment, are printed in a single spanning block
% at the bottom of the page.
%
% \danger Regular footnotes are printed above the block of critical
% notes. The respective places of these blocks can be interchanged by
% just loading the \pkg{fnpos} package in the
% preamble.\footcite{fnpos}
%
% \section{Laying Out the Apparatus Criticus}
% \label{sec:apparatus-layout}
%
% \subsection{General Hooks}
% \label{sec:general-hooks}
% Some hooks are shared by all layers of notes that are inserted in
% the apparatus criticus (e.g. sources, testimonia, variant readings
% \emph{\&c.})
%
% \DescribeMacro{\SetHooks} \cs{SetHooks}\marg{csv list of hooks} can
% be used either in the preamble or at any point of the document. The
% list of accepted
% hooks at the time of writing follows:---\\
% \DescribeOption{appfontsize} |appfontsize|$=$\meta{command}
% \hfill\tcboxverb{Default: \footnotesize}\\
% This option sets the size of the font to be used in the whole
% apparatus criticus. By default, it is the same as the size used for
% footnotes.\\
% \DescribeOption{refnumstyle} |refnumstyle|$=$\meta{command}
% \hfill\tcboxverb{Default: \bfseries}\\
% |refnumstyle| can be used to set the family, series or shape of the
% font used to print references to line numbers in the apparatus
% criticus. By default, numbers are printed in bold face. As an
% example, |refnumstyle=\normalfont| will have them printed in the
% font and shape selected by default for the document, while
% |refnumstyle=\bfseries\itshape| will have them
% printed in bold and italic.\\
% \DescribeOption{postrefnum} |postrefnum|$=$\meta{command \textbar\
% chars}\hfill\tcboxverb{Default: ~}\\
% |postrefnum| can be used to set what immediately follows the
% reference to line numbers. By default, it is |~|, namely an
% unbreakable space. As an example, |postrefnum=\hskip 0.5em| will
% insert a \unit[0.5]{em} space between the numerals and the beginning
% of all subsequent notes.\\
% \DescribeOption{lemmastyle} |lemmastyle|$=$\meta{command}
% \hfill\tcboxverb{Default: not set}\\
% \newfeature[v1.2] |lemmastyle| can be used to set the family, series
% or shape of the font used to print lemma texts in the apparatus
% criticus. For example, |lemmastyle=|\cs{bfseries} will print all
% instances of lemma text in bold while
% |lemmastyle=|\cs{color}|{blue}| will print them in blue.
% \DescribeOption{readingstyle} |readingstyle|$=$\meta{command}
% \hfill\tcboxverb{Default: not set}\\
% \newfeature[v1.2] |readingstyle| operates in the same way as
% |lemmastyle| but applies to variant readings.\\
% \DescribeOption{familysep} |familysep|$=$\meta{symbol}\verb+|reset+
% \phts\label{ref:familysep}\hfill\tcboxverb{Default: not set}\\
% \newfeature[v1.4] As described above \vpageref{ref:lem-wit},
% multiple witnesses must be recorded in the |wit| optional argument
% of the \cs{lem} and \cs{rdg} commands as comma-separated lists of
% sigla which can be further grouped into families by inserting spaces
% as separators just after commas at specific places. \pkg{ekdosis}
% saves and prints these spaces in the apparatus criticus but can be
% instructed to print any other symbol instead by means of
% |familysep|. For instance, |familysep={,}| has the separating spaces
% replaced with commas and |familysep={,\allowbreak}| does the same
% while further allowing breaks after commas at the end of
% lines. Finally, |familysep=reset| can be used to restore the default
% behavior.\\
% \DescribeOption{initialrule} |initialrule|$=$\meta{command}
% \phts\label{ref:initialrule}\hfill\bgroup\footnotesize
% \tcboxverb{Default: \rule{0.4\columnwidth}{0.4pt} (initially not set)}%
% \egroup \newfeature[v1.2] |initialrule| draws a separating rule
% between the edition text and all subsequent layers of critical
% notes. Of course, this option only makes sense when multiple-layer
% apparatus criticus are set. Therefore, it has no effect on
% single-layer apparatus criticus.\\
% \DescribeOption{noinitialrule}\hfill\tcboxverb{Default: not set}\\
% This is a no-value option. It removes any previously set
% |initialrule|.
% 
% An example of the way these hooks may be used is provided below in
% \vref{lst:shak-sonnet1}.
%
% \medskip\noindent\textbf{Limiting the Number of Entries per Page}
% \phts\label{ref:glimit}\\
% \DescribeOption{maxentries} |maxentries|=\meta{n} (where
% $n \geq 10$) \hfill\tcboxverb{Default: not set}\\
% \newfeature[v1.5] This option may be used to set a limit to the
% number of entries per page that \emph{all layers of critical notes
% taken together} may accept, notably when entries are so abundant in
% number that \pkg{ekdosis} may oscillate indefinitely between
% different sets of page decisions without being able to settle down.
% \danger It is also possible to restrict this option to a given layer
% of the apparatus criticus as described below
% \vpageref{ref:maxentries}. If |maxentries| be set both globally in
% \cs{SetHooks} and in \cs{DeclareApparatus} for specific layers, then
% the page will break when \emph{any} of the values defined as
% |maxentries| has been reached.
% 
% If |maxentries|$=$\meta{n} be set, then \pkg{ekdosis} will issue
% \cs{pagebreak} (namely \cs{penalty}|-10000|) just after the
% \emph{n\textsuperscript{th}} entry has been inserted in whichever
% layer of the apparatus criticus. As a result, the page will actually
% break at the end of the current line. The particulars of this
% technique will be discussed below in
% \vref{sec:oscillating-problem}.\\
% \DescribeOption{nomaxentries}\hfill\tcboxverb{Default: not set}\\
% |nomaxentries| does not accept any value and is equivalent to
% |maxentries=none|.
% 
% \medskip
% \noindent\textbf{Option Specific to the |layout=keyfloat| Global
% Setting}\footnote{See above \vref{ref:keyfloat-opt}.}\\
% \DescribeOption{keyparopts}%
% \phts\label{ref:keyparopts}|keyparopts|$=$\meta{csv options}
% \hfill\tcboxverb{Default: empty}\\
% \newfeature[v1.3] The comma-separated options that can be used are
% those described in the documentation of the \pkg{keyfloat}
% package.\footcite[sect.~2.3, \ppno~\pnfmt{13--15}]{keyfloat} As an
% example, |keyparopts={ft, tr={made with ekdosis},| %
% \allowbreak|lw=1.2}| will draw a tight frame around the apparatus
% block, have the words \enquote{made with \pkg{ekdosis}} printed
% below this block on the
% right and set its width to |1.2\linewidth|.
%
% \medskip\noindent
% \textbf{Options Specific to the |layout=fitapp| Global
% Setting}\footnote{See above \vref{ref:fitapp-opt}.}\\
% \DescribeOption{appheight}%
% \phts\label{ref:appheight}|appheight|$=$\meta{dimension}
% \hfill\tcboxverb{Default: 0.5\textheight}\\
% \newfeature[v1.3] This option is used to change the maximum height
% up to which the apparatus block is allowed to grow before the size
% of the characters is reduced to allow for more entries. The value
% must be a dimension, namely a number followed by a length unit, such
% as |0.65\textheight|, |18cm| or |6in|.\\
% \DescribeOption{fitalgorithm}%
% \phts\label{ref:fitalgorithm}
% \unskip|fitalgorithm|$=$\verb+fontsize|hybrid|areasize|squeeze+
% \hfill\tcboxverb{Default: fontsize}\\
% \newfeature[v1.3] The four algorithms that can be used to have the
% entries inserted in the apparatus criticus fit to the selected
% height are presented here from the tightest to the loosest, that is,
% the slowest to the fastest.\footnote{See \cite[446--449]{tcolorbox}
% for details and illustrative examples.} While it is advisable to
% limit the use of |fontsize| to high quality typesetting for
% camera-ready copies, |areasize| offers a satisfactory settlement
% when speed must be given an advantage for intermediate or draft
% copies. |squeeze| should be avoided as it gives results that are
% offensive to the sight and unacceptable to any reader.
%
% \subsection{Single-Layer Apparatus Criticus}
% \label{sec:single-layer-app}
% \paragraph{Specific Commands}
% Single-layer apparatus criticus can be laid out in a variety of
% ways with the following specialized commands, all of which can be
% used in the preamble or at any point of the document:---
%
% \DescribeMacro{\SetLTRapp}
% \DescribeMacro{\SetRTLapp}
% \cs{SetLTRapp} and \cs{SetRTLapp} are two argument-less commands to
% set the direction of the apparatus criticus, either left-to-right or
% right-to-left.
%
% \DescribeMacro{\SetSeparator} \cs{SetSeparator}\marg{separator} is
% used to change the separator between lemma texts and variant
% readings. By default, the separator is a closing square bracket
% followed by a space (\verb*+] +).
%
% \DescribeMacro{\SetSubseparator}\label{ref:setsubseparator}
% \newfeature[v1.4] \cs{SetSubseparator}\marg{subseparator} is used to
% set or change the \enquote{subseparator} between succeeding variant
% readings. By default, no subseparator is set.
%
% \danger As the subseparator applies to subsequent variant readings
% only, it is naturally preceded by a breakable space. This space can
% be removed by \cs{unskip}. As an example, what follows replaces the
% breakable space with an unbreakable space, then prints a colon as
% subseparator followed by a space:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\SetSubseparator{\unskip~: }
\end{minted}
% \iffalse
%</example>
% \fi
%
% \danger \DescribeMacro{\ekdsep} \DescribeMacro{\ekdsubsep}
% \phts\label{ref:ekdsep-subsep} Once the separator and if applicable
% the subseparator have been set, they can be accessed by \cs{ekdsep}
% and \cs{ekdsubsep} respectively. It is therefore advisable to use
% these commands instead of the mere symbols at whatever place one
% would have them printed.
%
% \DescribeMacro{\SetBeginApparatus}
% \cs{SetBeginApparatus}\marg{characters\textbar commands} can be used
% to append \meta{characters} or \meta{commands} at the beginning of
% the apparatus block. By default, nothing is appended. For instance,
% |\SetBeginApparatus{\textbf{Apparatus:}}| will append
% \enquote{\textbf{Apparatus:}} at the beginning of the apparatus
% block, while |\SetBeginApparatus{\hskip 1em}| will set an
% indentation of one em.
%
% \DescribeMacro{\SetEndApparatus}\phts\label{ref:setendapparatus}
% \cs{SetEndApparatus}\marg{characters} can be used to append
% \meta{characters} at the end of the apparatus block. By default,
% nothing is appended. \phts\label{ref:ending-dot}As an example of
% use, |\SetEndApparatus{.}| will have a period printed at the end of
% the apparatus as it is customary in some
% editions.\footnote{\label{fn:rm-dots}See also below
% \vpageref{sec:superfluous-dots} on how to remove superfluous dots.}
%
% \DescribeMacro{\SetUnitDelimiter}
% \cs{SetUnitDelimiter}\marg{delimiter} can be used to set the
% delimiter between entries in the apparatus criticus. By default,
% there is no delimiter except a simple space. \meta{delimiter} can be
% a broad space (such as |\hskip 0.75em| for instance as in the OCT
% series) or the divider-sign (‖, as in the Budé series).
%
% \DescribeMacro{\SetDefaultRule}
% By default, \pkg{ekdosis} draws a separating line between the
% edition text and the apparatus criticus. This line is initially
% defined as
% |\rule{0.4\columnwidth}{0.4pt}|. \cs{SetDefaultRule}\marg{line
% definition} can be used in the preamble or at any point of the
% document to change the default setting. Leaving this argument empty
% as in \cs{SetDefaultRule}|{}| removes the line.
%
% \DescribeMacro{\SetApparatusLanguage}
% \phts\label{ref:app-lang}\newfeature[v1.2]
% \cs{SetApparatusLanguage}\marg{languagename} can be used when it is
% needed to apply in the apparatus criticus a language different from
% the one that is selected in the edition text.
% 
% \DescribeMacro{\SetApparatusNoteLanguage}
% \phts\label{ref:app-note-lang}\newfeature[v1.3]
% \cs{SetApparatusNoteLanguage}\marg{languagename} can be used when it
% is needed to apply in text entries introduced by the mandatory
% argument of the \cs{note} command as described in
% \vref{ref:type-note}\===namely
% \cs{note}\oarg{options}\marg{text}\===a language different from the
% one that is selected in the edition text.
% 
% \paragraph{General Command}
% \DescribeMacro{\SetApparatus} \cs{SetApparatus}\marg{csv list of
% apparatus settings}\phts\label{ref:apparatus-settings-b}\\
% Finally, all the settings described above can also be collected in
% the argument of \cs{SetApparatus}. \cs{SetApparatus} accepts the
% following list of comma-separated |key=value| options:---\\
% \DescribeOption{direction} |direction|$=$\verb+LR|RL+
% \hfill\tcboxverb{Default: LR}\\
% The writing direction of the apparatus criticus, either
% left-to-right (|LR|) or right-to-left (|LR|).\\
% \DescribeOption{sep} |sep|$=$\meta{command \textbar\ chars}
% \hfill\tcboxverb{Default: ]␣}\\
% The separator between lemma texts and variant readings.\\
% \DescribeOption{subsep} |subsep|$=$\meta{command \textbar\ chars}
% \hfill\tcboxverb{Default: not set}\\
% The \enquote{subseparator} between succeeding variant readings.\\
% \DescribeOption{delim} |delim|$=$\meta{delimiter}
% \hfill\tcboxverb{Default: not set}\\
% The delimiter between entries in the apparatus criticus. As said
% above, there is no default delimiter except a simple space.\\
% \DescribeOption{bhook} |bhook|$=$\meta{characters\textbar commands}
% \hfill\tcboxverb{Default: empty}\\
% The characters or commands to be appended at the beginning of the
% apparatus block.\\
% \DescribeOption{ehook} |ehook|$=$\meta{characters}
% \hfill\tcboxverb{Default: empty}\\
% The characters to be appended at the end of the apparatus
% block.\footnote{See also n.~\vref{fn:rm-dots}.}\\
% \DescribeOption{rule} |rule|$=$\meta{command}
% \hfill\tcboxverb{Default: \rule{0.4\columnwidth}{0.4pt}}\\
% As described above, |rule| is used to draw the separating line
% between the edition text and the apparatus criticus.\\
% \DescribeOption{norule}\hfill\tcboxverb{Default: not set}\\
% |norule| does not accept any value and is used to remove the
% line.\\
% \DescribeOption{lang} |lang|$=$\meta{languagename}
% \newfeature[v1.2]\phts\label{ref:app-lang-opt}
% \hfill\tcboxverb{Default: not set}\\
% |lang=<languagename>| is used as described
% \vpageref[above]{ref:app-lang} when it is needed to apply in the
% apparatus criticus a language different from the one that is
% selected in the edition text. |languagename| can be any value
% accepted by \pkg{babel} or \pkg{polyglossia}.
% \DescribeOption{notelang} |notelang|$=$\meta{languagename}
% \newfeature[v1.3]\phts\label{ref:app-note-lang-opt}
% \hfill\tcboxverb{Default: not set}\\
% |notelang=<languagename>| is used as described
% \vpageref[above]{ref:app-note-lang} when is needed to apply in text
% entries introduced by the mandatory argument of the \cs{note}
% command as described in \vref{ref:type-note}\===namely
% \cs{note}\oarg{options}\marg{text}\===a language different from the
% one that is selected in the edition text. |languagename| can be any
% value accepted by \pkg{babel} or \pkg{polyglossia}.
% \phts\label{ref:apparatus-settings-e}
%
% As an example, an apparatus criticus with references to line numbers
% printed in normal font, a colon as a separator between lemma texts
% and variant readings, a broad space as a delimiter between entries
% and a \unit[0.7]{in} line above could be laid out as follows:---
%
% \phts\label{ex:single-layer-app-layout}
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\SetHooks{
  refnumstyle=\normalfont
}
\SetApparatus{
  sep={: },
  delim=\hskip 1em,
  rule=\rule{0.7in}{0.4pt}
}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \paragraph{Footnote Separator}
% \DescribeMacro{\footnoteruletrue} \DescribeMacro{\footnoterulefalse}
% As already seen above, \pkg{ekdosis} takes care of drawing a
% separating line between the edition text and the apparatus
% criticus. Therefore, it may be not desirable to have the standard
% \LaTeX\ \enquote{footnoterule} printed on every page where regular
% footnotes are found. \cs{footnoterulefalse} removes it while
% \cs{footnoteruletrue} leaves it untouched. The latter is set by
% default.
%
% \subsection{Multiple-Layer Apparatus Criticus}
% \label{sec:multilayer-apparatus}
% As said above in \vref{it:multilayer-feature}, \pkg{ekdosis} can
% print edition texts equipped with multiple-layer apparatus
% criticus. To take an example, most classical editions provide at
% least two layers of notes: one to collect references to testimonia
% or parallel passages (apparatus testium) and the other to record
% variant readings (the apparatus criticus \emph{stricto sensu}). The
% former is always printed above the latter.
%
% \danger The default single-layer apparatus criticus that is
% described above in \vref{sec:single-layer-app} is called |default|
% internally. If any additional layer of notes be declared in the
% preamble, this |default| layer must be included in the list of
% declared layers.\\
% \DescribeMacro{\SetDefaultApparatus}\phts\label{ref:ekd-default-app}
% \cs{SetDefaultApparatus}\marg{name} can be used at any point of the
% document to change the name to be used as the default one by
% \pkg{ekdosis}.
%
% \subsubsection{Declaring Additional Layers}
% \label{sec:declaring-layers}
% \DescribeMacro{\DeclareApparatus}
% \cs{DeclareApparatus}\marg{name}\oarg{csv list of apparatus
% settings} is a preamble-only command. As a mandatory argument, it
% takes the name of the new layer of notes to be inserted in the
% apparatus block. Declared layers are then printed one below the
% other in the exact same order as they are declared in the
% preamble. Therefore, one additional layer meant to print the
% testimonia above the variant readings (apparatus testium) can be
% declared as follows:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}{latex}
% preamble:
\DeclareApparatus{testium}
\DeclareApparatus{default}
\end{minted}
% \iffalse
%</example>
% \fi
%
% In this example, |testium| is a new name for |default|, as said
% just above, is already known to \pkg{ekdosis} and used as the
% default layer of notes. Furthermore, as |testium| is declared before
% |default|, \pkg{ekdosis} will print the testimonia at the top of the
% apparatus block.
%
% \subsubsection{Laying Out Layers With The Optional Argument
% of \cs{DeclareApparatus}}
% \label{sec:layout-layers}
% \DescribeOption{direction}
% \DescribeOption{sep}
% \DescribeOption{subsep}
% \DescribeOption{delim}
% \DescribeOption{bhook}
% \DescribeOption{ehook}
% \DescribeOption{rule}
% \DescribeOption{norule}
% \DescribeOption{lang}\phts\label{ref:apps-lang-opt}
% \DescribeOption{notelang}
% With regard to layout, any declared layer inherits the default values
% described above in \vref{sec:single-layer-app}. That said, as the
% optional argument of \cs{DeclareApparatus} accepts the exact same
% |key-value| options as \cs{SetApparatus} described
% \vpagerefrange{ref:apparatus-settings-b}{ref:apparatus-settings-e},
% \pkg{ekdosis} provides a straightforward mechanism to have any layer
% printed in a distinct layout.
%
% To return to the example provided
% \vpageref[above]{ex:single-layer-app-layout}, one could keep the
% same settings as above for the variant readings, declare an
% apparatus testium with a closing square bracket as a separator and
% finally remove the line between the testimonia and the variant
% readings like so:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[numbersep=-.5\linewidth]{latex}
\SetHooks{
  refnumstyle=\normalfont,
  initialrule=\rule{0.7in}{0.4pt}

\end{minted}
% \iffalse

% \fi
%
% \begin{remarks}
% \item The general hook \texttt{initialrule} used here (l.~3) is

% \item \cs{relax} (l.~13) is a \TeX\ primitive that instructs to do

%   untouched the subsequent carriage return: as a result, the layers
%   are visually separated from one another by a blank line. With the
%   latter everything is removed, carriage return included.

% \paragraph{Limiting the Number of Entries per Page}
% \phts\label{ref:maxentries}
% In some instances, it may be useful to set a limit to the number of
% entries per page that a given layer of critical notes may accept,
% notably when entries are so abundant in number that \pkg{ekdosis}
% may oscillate indefinitely between different sets of page decisions
% without being able to settle down.\\
% \DescribeOption{maxentries} |maxentries|=\meta{n} (where $n \geq
% 10$) \hfill\tcboxverb{Default: not set}
% \danger It is also possible to set a maximum number of entries for
% all layers of critical notes taken together as described above 
% \vpageref{ref:glimit}. If |maxentries| be set both globally in
% \cs{SetHooks} and in \cs{DeclareApparatus} for specific layers, then
% the page will break when \emph{any} of the values defined as
% |maxentries| has been reached.
% 
% If |maxentries|$=$\meta{n} be set, then \pkg{ekdosis} will issue
% \cs{pagebreak} (namely \cs{penalty}|-10000|) just after the
% \emph{n\textsuperscript{th}} entry has been inserted in the layer of
% the apparatus criticus this option is related to. As a result, the
% page will actually break at the end of the current line. The
% particulars of this technique will be discussed below in
% \vref{sec:oscillating-problem}.
%
% \section{Inserting Notes in Multiple-Layer Apparatus}
% \label{sec:notes-in-multilayer-app}
% As said above in \vref{sec:multilayer-apparatus}, \pkg{ekdosis}
% initially sets one layer of notes that is called the
% \textooquote|default|\textcoquote\ layer. As a result, any note
% inserted within the argument of \cs{app}|{}| as described
% \vpageref{ref:app-cmd} will go into that layer of the apparatus,
% unless \cs{SetDefaultApparatus} has been used to set another
% name for the default layer (see above
% \vpageref{ref:ekd-default-app}).
%
% \subsection{Variant Readings}
% \label{sec:variant-readings}
% In most cases, all variant readings go into the
% \textooquote|default|\textcoquote\ layer of the apparatus
% criticus. But in some other cases, for example when the manuscripts
% used refer to different recensions, it may happen that one wishes to
% record the related variants in separate layers. As already described
% \vpageref{ref:app-type}, the |type| optional argument of the
% \cs{app} command can be used to insert lemma texts and associated
% variants in any other \enquote*{declared} layer of the apparatus
% criticus.
%
% The following example assumes that some edition text is received in
% two different recensions and the variant readings that belong to the
% first recension are recorded in the default layer of notes while
% those of the second recension are to be printed in a second layer,
% below the default one. First, both layers must be declared in the
% preamble in sequence, like so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\DeclareApparatus{default} % default layer
\DeclareApparatus{rec2} % additional layer below the default one
\end{minted}
% \iffalse
%</example>
% \fi
%
% Should one wish to refer to |rec1| as the default layer, then
% \cs{SetDefaultApparatus} must be used, like so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\SetDefaultApparatus{rec1}
\DeclareApparatus{rec1} % new layer set as default
\DeclareApparatus{rec2} % additional layer below the default one
\end{minted}
% \iffalse
%</example>
% \fi
%
% Then, whatever option has been chosen, lemma texts and variants
% inserted with \cs{app}|{}| will go into the upper, default layer of
% notes, while those inserted with \cs{app}|[type=rec2]{}| will go
% into the lower one:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
Some \app{
  \lem{word}
  \rdg{reading}
} to go into the default layer of notes.

Some \app[type=rec2]{
  \lem{note}
  \rdg{comment}
} to be recorded as part of the second recension.
\end{minted}
% \iffalse
%</example>
% \fi
%
% \danger At any rate, |type=default| or |type=rec1|, depending on
% what has been chosen, must be used should the editor wish to retain
% that information in the \texttt{TEI xml} output file.
%
% \subsection{Other Notes for Comments, Sources or Testimonia}
% \label{ref:type-note}
% Additional layers of notes can be used to print short comments or to
% record references to texts quoted by the author of the edited text
% or references to the edited text by other authors or
% translators. The former set is called an \emph{apparatus fontium}
% while the latter is called an \emph{apparatus testium}.
%
% \danger From a technical standpoint, these notes are very different
% from the short editorial notes inserted between lemma texts and
% variant readings that have been described above
% \vpageref{ref:editorial-notes}. However, for the sake of consistency
% with \texttt{TEI xml} encoding, \pkg{ekdosis} uses the same command
% \cs{note} to insert both kinds of notes.
%
% \danger One must also keep in mind that the notes that are described
% in this section refer either to a single word or to a span of
% text. By consequence, as boundaries must always be set outside spans
% of text, notes must be inserted immediately before the word or words
% they are related to. As a result of this rule, all spaces subsequent
% to \cs{note} are ignored.
%
% \needspace{2\baselineskip}
% \DescribeMacro{\note} \cs{note}\oarg{options}\marg{text}\\
% As said above, \cs{note}, when found outside \cs{app}|{}|, is used
% to insert in additional layers of the apparatus short comments or
% references to texts quoted or cited in the edition text. It accepts
% the following comma-separated list of |key-value| optional
% arguments:---\\
% \DescribeOption{type} |type|$=$\meta{type}\\
% |type| is used to specify the name of the layer where the note is to
% be printed.\footnote{See \vref{sec:declaring-layers} to learn how to
% declare and lay out new layers of notes.}\\
% \DescribeOption{nodelim} |nodelim|$=$\verb+true|false+\\
% \newfeature[v1.5] This named argument does not need a value as it
% defaults to |true| if used. This option removes the delimiter that
% is printed just before the note in the apparatus criticus.\\
% \DescribeOption{sep} |sep|$=$\meta{command \textbar\ chars}\\
% The separator between the lemma text and the contents of the note.\\
% \DescribeOption{nosep} |nosep|$=$\verb+true|false+\\
% This named argument does not need a value as it defaults to |true|
% if used. Obviously, |nosep| removes the separator mentioned
% above.\\
% \DescribeOption{lem} |lem|$=$\meta{lemma text}\\
% |lem| is the span of text the note is about. It may consist of one
% or more words, or of an abridged lemma text.\\
% \DescribeOption{num} (no-value argument)\newfeature[v1.3]\\
% |num| takes no value. If used, this argument instructs to print any
% line number that \pkg{ekdosis} may have decided not to print in the
% apparatus criticus before the note.\\
% \DescribeOption{nonum} (no-value argument)\\
% Compared to |num|, |nonum| does the opposite. If used, any number
% that \pkg{ekdosis} may have decided to print before the note
% is suppressed.\\
% \DescribeOption{labelb} |labelb|$=$\meta{label}
% \hfill\tcboxverb{Mandatory}\\
% |labelb| is the unique label to serve as a reference for the point
% immediately preceding the lemma text.  \danger |labelb| is used by
% \pkg{ekdosis} to print the line numbers in the apparatus criticus
% and to set the |left()| XPointer should \texttt{TEI} output be
% required. Therefore, it must be specified. Otherwise, \pkg{ekdosis}
% will issue an error message. However, two strictly consecutive
% \cs{note} commands are allowed to share the same |labelb| value for
% it may happen that consecutive notes need to refer to spans of text
% that begin at the exact same location. In this case, \pkg{ekdosis}
% generates only one \cs{linelabel} and one corresponding
% |<anchor>| element in the \texttt{TEI xml} file.\\
% \DescribeOption{labele} |labele|$=$\meta{label}\\
% |labele| is the unique label to serve as a reference for the point
% immediately following the lemma text. Contrary to |labelb|, |labele|
% may be left unspecified if the note be only about one word. If the
% note be about a span, then |labele| must be specified.\\
% \DescribeMacro{\linelabel} \cs{linelabel}\marg{label}\\
% If |labele|$=$\meta{some\_label} be specified in the optional
% argument of \cs{note}, \cs{linelabel}\marg{some\allowbreak\_label}
% must be inserted immediately after the span of text that the note is
% about so that \pkg{ekdosis} can locate the exact point where the
% lemma text addressed by the note ends, like so:---

% \subsection[The Standard \textsf{verse} Environment]{The Standard
% \env{verse} Environment}
% \label{sec:stand-verse-env}
%
% In order to typeset verse texts or poems, \LaTeX\ provides the
% standard \env{verse} environment. Within this environment, |\\| is
% normally used to end lines, with the exception of the last line. As
% a result, stanzas are separated from one another by a blank line.
%
% \pkg{ekdosis} provides \env{ekdverse} which is recommended for use
% in place of the standard \env{verse} environment. By default,
% \env{ekdverse} produces the same result as \env{verse}.  However,
% \pkg{ekdosis} deviates a little from the standard usage for it needs
% all lines of poetry to be ended by |\\| as a distinct marker. In the
% following listing, stanzas are visually separated from one another
% by an additional vertical space of \unit[2]{ex} (l.~5). Between
% stanzas, |%| is used to prevent \TeX\ from
% introducing a blank line. But a blank line\===or even no blank
% line\===would produce the exact same result:---

% which has been ignored.  This is because it is about as much as the

%
% \subsection[The \textsf{verse} Package]{The \pkg{verse} Package}
% \label{sec:verse-package}
% \newfeature[v1.2]
% \pkg{ekdosis} can use the facilities offered by the excellent
% \pkg{verse} package\footcite{verse} to which it adds a specific
% environment for the encoding of line groups such as
% stanzas. Furthermore, as the \pkg{verse} package provides its own
% numbering mechanism, the lines can be numbered independently of
% prose text.\footnote{See \vpageref{ref:verse-lineation} for
% details.}
%
% \danger For what is described in this section to operate,
% \pkg{ekdosis} must be loaded with the global option |poetry=verse|
% as explained above \vpageref{ref:poetry-opt}. Simply loading the
% \pkg{verse} package by means of \cs{usepackage} will have no effect.
%
% \danger The foregoing does not apply if the \cls{memoir} class be
% used.\footcite{memoir} In this case, \pkg{ekdosis} automatically
% uses the code provided by this class without the need to set
% the global option |poetry=verse|.
%
% \paragraph{Compatible Verse Commands}
% The reader is invited to refer to the documentation of the
% \env{verse} package for detailed information.  Within the
% \env{ekdverse} environment, |\\| \emph{must be used} at the end of
% each line, as follows:---
% \begin{enumerate}
% \item |\\| is the standard command to be used at the end of each
%   line.
% \item |\\!| must be used at the end of stanzas or line groups
%   instead of |\\|.
% \item |\\*| does the same as |\\| except that it prohibits a page
%   break after the line.
% \item |\\>| \label{ref:vlinebreak-indent}is for line breaks within a
%   verse line.
% \item |\\+| \newfeature[v1.4] \label{ref:vlinebreak-noindent}does
%   the same as |\\>| but without indenting the subsequent line which
%   further complies to any already defined indent pattern.
% \end{enumerate}
%
% All of these commands can take a dimension as optional argument,
% like so: |\\[30pt]|, |\\![30pt]|, |\\*[30pt]|, |\\>[30pt]| or
% |\\+[30pt]|. If |\\|, |\\!|, |\\*| or |\\+| be used, a vertical
% space of the dimension specified is added between lines, whereas
% |\\>[...]| adds an horizontal space after the line break.
%
% \DescribeMacro{\vin} \phts\label{ref:verse-vin}\cs{vin} indents a
% verse line by a length which is by default \unit[1.5]{em}. This
% length is stored as \cs{vgap} and can be changed by \cs{setlength}
% or \cs{addtolength}.
%
% \paragraph{The \env{ekdverse} Environment}
% \DescribeEnv{ekdverse} \cs{begin}|{ekdverse}|\oarg{options} \dots\
% \cs{end}|{ekdverse}|\phts\label{ref:ekdverse-syntax}\\
% This environment is used to hold verse lines as described above and

% \enquote{name$=$value} arguments are accepted:---\\
% \DescribeOption{width} |width|$=$\meta{length}
% \hfill\tcboxverb{Default: \linewidth}\\
% If |width| be supplied, it is taken as a length in relation to which
% the entire contents of the environment are to be horizontally
% centered. If given, this dimension may correspond to an average line
% or to the longest line of the line group. To this end, the standard
% \LaTeX\ command \cs{settowidth} can be used, like so:--- %
% \iffalse

% \end{remarks}
% \DescribeOption{type} |type|$=$\meta{type}
% \hfill\tcboxverb{Default: not set}\\

% \paragraph{Stanzas}
% As can be seen above, the \LaTeX\ \env{ekdverse} environment is
% translated into the \texttt{TEI xml} |<lg>| element. The |type|
% attribute may then be used to name the type of unit encoded by this
% element.
%
% \DescribeEnv{ekdstanza} \cs{begin}|{ekdstanza}|\oarg{options} \dots\
% \cs{end}|{ekdstanza}| \phts\label{ref:ekdstanza}\\
% This environment is used within \env{ekdverse} to encode succeeding
% stanzaic forms. Within \env{ekdstanza}, the last line is ended by
% |\\!| or |\\| depending on whether an additional vertical space is
% required between stanzas. This environment may receive an optional
% argument in which the following \enquote{name$=$value} argument is
% accepted:---\\
% \DescribeOption{type} |type|$=$\meta{type}
% \hfill\tcboxverb{Default: not set}\\
% As in the case of \env{ekdverse}, this named argument is used in the
% \texttt{TEI xml} output to name the type of unit encoded within the
% |<lg>| element, viz.\ \enquote{quatrain}, \enquote{couplet} and the
% like.
%
% \paragraph{Indentation Patterns}
% \pkg{ekdosis} can use the \env{patverse} environment and its
% associated command \cs{indentpattern} that are provided by the
% \pkg{verse} package. As described in the documentation of this
% package,\footcite[6]{verse} the indentation pattern consists of an
% array of digits, \emph{d\textsubscript{1}} to
% \emph{d\textsubscript{n}}, where the \emph{n\textsuperscript{th}}
% line is indented by \emph{d\textsubscript{n}} times the amount of
% \cs{vgap} described above \vpageref{ref:verse-vin}.
%
% The overall structure of lines grouped into stanzas may look as
% follows:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}
\begin{ekdverse}[type={+\emph{overall type}+}]
  \identpattern{+\emph{digits}+}

\end{ekdverse}
\end{minted}
% \iffalse
%</example>
% \fi
%
% Of course, if no indentation pattern be required or be only required
% occasionally, \env{patverse} (ll.~3 and 10) and \cs{indentpattern}
% (l.~2) are of no use:---

% A detailed example follows. It is taken from
% \citename{McDonald1916}{editor}'s edition of Shakespeare's
% \emph{Sonnets} from the Quarto of 1609 with variorum
% readings.\footcite[Sonnet~1, \pno~15]{McDonald1916} Compared to
% \citename{McDonald1916}{shorteditor}'s edition, an effort has been
% made to use the typography and punctuation of the original edition
% which can be consulted online at the British Library's
% website.\footnote{Shake-speares \emph{Sonnets}. Neuer before
% Imprinted. (A Louers Complaint. By William
% Shake-speare.). \url{https://www.bl.uk/collection-items/first-edition-of-shakespeares-sonnets-1609}.
% Call number \texttt{C.21.c.44}, fol.~B.} However, this typographical
% refinement has been retained for the sonnet only. For the sake of
% clarity, the line numbers and the apparatus criticus use modern
% typography. The references to line numbers in the apparatus criticus
% have been made consistent with
% \citename{McDonald1916}{shorteditor}'s edition, as have the entries
% in the apparatus criticus, namely the bare line number followed by a
% dot, then the lemma text in bold face, then the variant in italic
% shape:---

% \section{Lineation Settings}
% \label{sec:lineation}
% \danger \pkg{ekdosis} uses \pkg{lineno} internally for line
% numbering.\footcite{lineno} But it must be noted that \pkg{ekdosis}
% strictly prohibits the \enquote{pagewise} mode of operation that is
% provided by \pkg{lineno}. As a result of this hinderance, all
% \enquote{margin switching} functions of \pkg{lineno} are disabled
% within the environments that are specific to \pkg{ekdosis},
% viz. \env{ekdosis} and \env{alignment}.
%
% That said, \pkg{ekdosis} provides equivalents of its own to handle
% the line numbers the same way as \pkg{lineno}'s \enquote{pagewise}
% mode of operation does.
%
% \DescribeMacro{\SetLineation} \cs{SetLineation}\marg{csv list of
% options} may be used in the preamble or at any point of the document
% to set lineation preferences. Its argument processes the |key=value|
% options that follow:---\\
% \textbf{General Options}\\
% \DescribeOption{lineation} |lineation|$=$\verb+page|document|none+
% \hfill\tcboxverb{Default: document}\\
% |lineation=document| has the lines numbered continuously throughout
% the document while |lineation=page| instructs \pkg{ekdosis} that the
% numbering should start afresh at the top of each page. |none| does
% the same as |page| but prevents the numbers from being printed in
% the margins while keeping them in use in the apparatus criticus.\\
% \DescribeOption{modulo} |modulo| \hfill\tcboxverb{Default: not set}\\
% |modulo| does not accept any value. When this option is set, every
% fifth line is numbered.\\
% \DescribeOption{modulonum} |modulonum|$=$\emph{n} (where \emph{n} is
% an integer)\hfill\tcboxverb{Default: not set}\\
% |modulonum| allows to modify the interval between the numbers that
% are printed. |modulo| must be set for this option to have effect. As
% examples, |modulo, modulonum=3| has every third line numbered and
% |modulonum=1| disables modulo numbering.\\
% \DescribeOption{margin} |margin|$=$\verb+right|left|inner|outer+
% \hfill\tcboxverb{Default: left}\\
% |margin| sets the margin in which the line numbers are to be
% printed.\\
% \DescribeOption{numbers} |numbers|$=$\verb+elided|full+
% \hfill\tcboxverb{Default: elided}\\
% This option only has effect on the numbers that are printed in the
% apparatus criticus. |numbers=elided| applies on spans of numbers and
% elides the last number of a range to the fewest number of figures
% possible\---viz. 35--7, 129--31 \emph{\&c.}\---without eliding
% digits in the group 10 to 19 in each hundred\---viz. 17--19, 115--18
% \emph{\&c.} |numbers=full| leaves the numbers untouched.\\
% \DescribeMacro{\innerlinenumbers} \DescribeMacro{\outerlinenumbers}
% \cs{innerlinenumbers} and \cs{outerlinenumbers} are equivalent to
% \cs{SetLineation}|{numb|\allowbreak|ers=outer}| and
% \cs{SetLineation}|{numbers=inner}| respectively. Both commands are
% complementary to \cs{rightlinenumbers} and \cs{leftlinenumbers}
% already provided by the \pkg{lineno} package.\\

%
% \paragraph{Useful Lineation Commands}
% As implied above, pretty much all commands that are provided by the
% \enquote{running} mode of operation of the \pkg{lineno} package will
% work with \pkg{ekdosis}, notably the following:---\\
% \DescribeMacro{\modulolinenumbers} \cs{modulolinenumbers}\oarg{n}
% can be used to enable or modify modulo line numbering as described
% above.\\
% \DescribeMacro{\resetlinenumber} \cs{resetlinenumber}\oarg{n} resets
% the line number to one or to \emph{n} if specified.\\
% \DescribeMacro{\linenumberfont}
% \cs{renewcommand}|{\linenumberfont}|\marg{commands} can be used to
% set the font used for the line numbers that are printed in the
% margins. By default, the definition is
% \cs{normalfont}\cs{footnotesize}.\\
% \DescribeMacro{\linenumbersep} \cs{linenumbersep} is the distance
% between the numbers and the margin. By default, this distance is set
% to \unit[10]{pt}. It can be redefined like so:
% \cs{setlength}\cs{linenumbersep}\marg{length}.
%
% \paragraph{Poetry Lineation Commands}
% In addition to these commands, if \pkg{ekdosis} be loaded with the
% global option |poetry=verse| as described above in
% \vref{sec:verse-package}, the commands dedicated to line numbering
% that are provided by the \pkg{verse} package can be used.\\
% \DescribeMacro{\vmodulolinenumbers} \newfeature[v1.4]
% \cs{vmodulolinenumbers}\oarg{n} can be used to enable or modify
% verse modulo line numbering as described above.\\
% \DescribeMacro{\resetvlinenumber} \cs{resetvlinenumber}\oarg{n} has
% for lines of verse the same effect as \cs{resetlinenumber} for
% lines of prose text.\\
% \DescribeMacro{\verselinenumfont}
% \cs{verselinenumfont}\marg{commands} can be used to set the font
% used for lines of verse. By default, the definition is
% |\normalfont\footnotesize|.\\
% \DescribeMacro{\vrightskip} The \pkg{verse} package prints the
% numbers at the distance \cs{vrightskip} into the right margin. This
% distance can be redefined by means of \cs{setlength} like so:
% \cs{setlength}\cs{vrightskip}\allowbreak\marg{length}.
%
%
% \paragraph{Labels}
% \DescribeMacro{\linelabel} \DescribeMacro{\ref} In prose as well
% as in poetry texts, \cs{linelabel}\marg{label} sets a line label
% that can be referred to with \cs{ref}\marg{label}.
%
% As an example, what follows has every fifth line number printed in
% the inner margins. Additionally, the numbering shall start afresh at
% the top of each page:---

% \section{Languages}
% \label{sec:languages}
% \danger \pkg{ekdosis} is fully compatible with \pkg{babel}.
% \enquote{Fully compatible} means that all features provided by
% \pkg{babel}, including language switching commands, are supported by
% \pkg{ekdosis}. \pkg{ekdosis} is also compatible with
% \pkg{polyglossia} with one notable exception: \pkg{luabidi}, which
% \pkg{polyglossia} loads for languages written from right to left, is
% not supported by \pkg{ekdosis}, and most probably never will
% be. That said, as far as the author could see, single-layer
% apparatus, as described in \vref{sec:single-layer-app}, can be
% typeset within the Arabic environment that is provided by
% \pkg{polyglossia}. Unfortunately, the same cannot be said for
% multiple-layer apparatus.
%
% Whether \pkg{babel} or \pkg{polyglossia} is used, \pkg{ekdosis}
% automatically applies the current language to the entries of the
% apparatus criticus, including the fonts that may have been
% associated to the languages in the preamble. In this respect, as
% \pkg{polyglossia} can use the same language switching commands as
% \pkg{babel},\footcite[See][3.2 \pno~14]{polyglossia} the general
% advice given above in \vref{sec:alignment-hooks} applies in all
% cases. As regards setting languages in the \texttt{TEI xml} output
% file, the reader is invited to refer to point \vref{it:lang-subopt},
% and \vref{sec:teixml-output} including the example provided
% \vpageref{ref:ancientgreek-ex}.
%
% \danger In some cases, it may be needed to apply in the apparatus
% criticus a language different from the one that is selected in the
% edition text.  To this end, \pkg{ekdosis} provides a set of
% facilities which are described
% \vpagerefrange{ref:app-lang}{ref:app-lang-opt} for single-layer
% apparatus and \vpageref{ref:apps-lang-opt} for multiple-layer
% apparatus.
%
% \subsection{Languages Written From Right to Left}
% \label{sec:rtl-languages}
% As said above, \pkg{polyglossia} is not supported by \pkg{ekdosis}
% for languages that are written and read from right to left, like
% Arabic, Hebrew or Syriac. However, as \pkg{babel} is supported and
% can be loaded concurrently with \pkg{polyglossia}, an easy way is to
% use \pkg{babel} to print such languages.
%
% \danger The reader is invited to refer to and become acquainted with
% the relevant parts of the documentation of the \pkg{babel}
% package.\footcite{babel}
%
% \paragraph{\pkg{babel} Only}
% In the following example, \pkg{babel} is used exclusively to set
% three different languages: Arabic, ancient Greek and English:---
%
% \captof{Multilingual editions with \pkg{babel} only}

%
% \begin{remarks}
% \item As can be seen, \pkg{fontspec} has been loaded before
%   \pkg{babel}. To the author's knowledge, this gives better results
%   when \cs{babelfont} is used.
% \item Line~3 loads \pkg{babel} and instructs it to use English as
%   the default language and ancient Greek as a second optional
%   language. The built-in |bidi| mechanism provided by \pkg{babel} is
%   not enabled. As a result, specific language switching commands for
%   Arabic must be defined just as it must be for every other
%   language.
% \item Line~4 does not load any Arabic, but instructs \pkg{babel}
%   that it should use the Arabic font that is set below with
%   \cs{babelfont} whenever an Arabic letter is encountered.
% \item Lines~6--8 select the fonts: |Old Standard| is the default
%   font to be used for Roman shape (l.~6); the same font is used for
%   Greek, with some additional Open Type features enabled; finally,
%   the |Amiri| font is used for Arabic.
% \item Lines~10--11 define so-called \enquote{tags} for easier access
%   to ancient Greek through \cs{begin}|{ancient|\allowbreak|greek}|
%   \dots\ \cs{end}|{ancientgreek}| for running paragraphs and
%   \cs{textancientgreek}\marg{text} for short insertions of Greek in
%   English text. \cs{sg}\marg{text} is just a shorthand for this
%   latter command.
% \item Finally, lines~13--14 define simple language switching
%   commands for Arabic. As can be seen, no commands other than the
%   \LuaTeX\ primitives \cs{pardir} and \cs{textdir} have been used
%   for \pkg{babel} already takes care of selecting the Arabic
%   font. \cs{RL} is for short insertions of Arabic words in English
%   paragraphs while \cs{begin}|{Arabic}| \dots\ \cs{end}|{Arabic}| is
%   for running paragraphs of Arabic text.
% \end{remarks}
%
% \paragraph{Changing the Writing Direction}
% \DescribeMacro{\setRL} \DescribeMacro{\setLR} \cs{setRL} and
% \cs{setLR} are two argument-less commands provided by \pkg{ekdosis}
% that can be used to change the writing direction of running
% paragraphs. The former sets the direction from right to left and the
% latter form left to right. If \pkg{babel} be set as above,
% \cs{setRL} \dots\ \cs{setLR} can be used in place of
% \cs{begin}|{Arabic}| \dots\ \cs{end}|{Arabic}|.
% 
% \paragraph{\pkg{polyglossia} Associated With \cs{babelprovide}}
% What follows illustrates how \pkg{babel} can be used conjointly with
% \pkg{polyglossia} for the same three languages as above without
% having to load \pkg{luabidi}:---

%
% \begin{remarks}
% \item Line~3 just loads \pkg{babel} with no default language.
% \item Lines~4 and 8 are used to have the Arabic font automatically
%   selected as above.
% \item Lines~14--15 define the exact language switching commands that
%   would have been defined if \pkg{polyglossia} and \pkg{luabidi} had
%   been used for Arabic.
% \end{remarks}
%
% As one can see, the important points about languages written from
% right to left are to use \pkg{babel} only to select the Arabic
% fonts, avoid using the bidirectional mechanism it provides and
% define commands and environments that use only \LuaTeX\ primitives
% to set the writing direction. Then, an Arabic edition text\---to

%
% \subsection{Using \pkg{arabluatex}}
% \label{sec:using-arabluatex}
% \pkg{arabluatex} is a \hologo{LuaLaTeX} package that provides
% commands and environments which return Arabic writing from an ASCII
% transliteration (either Arab\TeX\ or Buckwalter
% scheme).\footcite{arabluatex} It is particularly well-suited for
% complex documents such as critical editions where a lot of commands
% intertwine with Arabic writing. \pkg{arabluatex} can output Unicode
% Arabic in the same modes as \pkg{arabtex}\footcite{arabtex} or in
% different accepted standards of romanization. It is also able to
% produce a duplicate of the original |.tex| source file in which all
% |arabtex| or |buckwalter| strings are replaced with Unicode
% equivalents, either in Arabic script or in any accepted standard of
% transliteration.\footcite[\mkbibquote{Exporting Unicode Arabic
% to an External File}]{arabluatex}
%
% \pkg{arabluatex} is fully supported by \pkg{ekdosis}. The following
% example illustrates how \pkg{arabluatex} and \pkg{ekdosis} interact
% with each other to produce distinct \texttt{TEI xml} outputs from a
% single |.tex| source file:---
%
% \captof{\pkg{ekdosis} and \pkg{arabluatex}}[\label{lst:arabluatex-ekd}]

%
% However, assuming that the source file is called |source.tex|,
% \pkg{ekdosis} produces as instructed from this file an additional

% \iffalse

% \fi
%
% At the same time, \pkg{arabluatex} is instructed to produce on its

% which all |arabtex| strings found within \cs{begin}|{arabexport}|
% \dots\ \cs{end}|{arabexport}| (see \vref{lst:arabluatex-ekd},

%
% \section{Divisions of the Body}
% \label{sec:body-divisions}
% The features that are described in this section call for one general
% remark.  \pkg{ekdosis} is designed to figure out where any \LaTeX\
% command that is converted to a \texttt{TEI} opening element allowed
% to nest recursively, such as |<div>|, |<lg>| and the like, is to be
% closed, even though there is no explicit indication of the point
% where the closure occurs. Thoroughly scanning \LaTeX\ source files
% with \textsf{Lua} functions which involve complex string matching
% and recursions was required, as \LaTeX\ \enquote*{open} commands
% such as \cs{chapter} or \cs{section} only act as milestones,
% contrary to \texttt{TEI} elements.
% 
% \danger It must be noted that the two styles described hereinafter
% are mutually exclusive. \texttt{TEI xml} forbids that both be
% combined within a single |<body>| element.\footnote{See
% \url{https://tei-c.org/release/doc/tei-p5-doc/en/html/DS.html\#DSDIV}.}
% As a result, \pkg{ekdosis} will disregard whichever one is not
% selected.
% \vskip\baselineskip
%
% \subsection{\LaTeX\ Standard Divisions}
% \label{sec:latex-divs}
% \pkg{ekdosis} can use the \LaTeX\ standard textual divisions, such
% as \cs{book}, \cs{chapter}, \cs{section} and the like.
%
% \danger However, to have these divisions properly translated into
% \texttt{TEI} numbered |<div>| elements, the |divs| general option
% must be set to |latex| explicitly\---viz. |divs=latex|\---as
% described above \vpageref{ref:divs-opt}.
%
% \danger As the \env{alignment} environment that is provided by
% \pkg{ekdosis} places all aligned texts within \texttt{TEI xml}
% un-numbered |<div>| elements and \LaTeX\ textual divisions are
% converted into numbered |<div|\textsubscript{\emph{n}}|>| elements,
% inserting such divisions in texts to be aligned will result in an
% invalid \texttt{TEI xml} output. Instead, un-numbered divisions
% through \cs{ekddiv} must be used as described below in
% \vref{sec:ekddiv}.
%
% Once |divs| has been set to |latex|, \pkg{ekdosis} converts
% \cs{book}, \cs{part}, \cs{chapter}, \cs{section}, \cs{subsection}
% and \cs{subsubsection} into corresponding \texttt{TEI}
% \enquote*{numbered} |<div|\textsubscript{\emph{n}}|>| elements,
% where $1\leq n\leq 6$.
%
% \paragraph{Adjusting the Levels of Textual Subdivisions}
% \DescribeMacro{\MkBodyDivs}
% \cs{MkBodyDivs}\marg{div1}\marg{div2}\marg{div3}\allowbreak\marg{div4}\marg{div5}\marg{div6}
% takes six mandatory arguments. This command can be used in the
% preamble or at any point of the document to make the number of the
% first-level subdivision of the edition text, viz.\ |<div1>|, match
% to any \LaTeX\ command other than \cs{book}. For example, if
% \cs{section} be the highest-level sectional command used, then
% \cs{MkBodyDivs}|{section}{subsection}{subsubsection}{}{}|\allowbreak|{}|
% will have \cs{section}, \cs{subsection} and \cs{subsubsection}
% converted into |<div1>|, |<div2>| and |<div3>| respectively.
%
% \paragraph{Inserting Variants in Headings}
% Variant readings can be inserted in headings. In this case, the
% optional argument of the \LaTeX\ sectional command must naturally be
% used to prevent variants from going into headers, footers or the
% table of contents, like so:\footnote{On the use of \texttt{egomute}
% (l.~13), see above \vref{it:egomute}.}---

% \subsection{\texttt{TEI} Un-numbered Divisions}
% \label{sec:ekddiv}
% \danger As already described \vpageref{ref:divs-opt}, the
% un-numbered style of division is the one that is set by default. It
% is congruous to the general option |divs=ekdosis|.
%
% This style provides a flexible mechanism in which format and
% presentation are separated from content. It is designed to meet the
% requirements of classical and literary texts the divisions of which
% may depend on many different received traditions.
%
% \DescribeMacro{\ekddiv} \cs{ekddiv}\marg{key-value arguments} is the
% unique sectional command provided by \pkg{ekdosis}. This command
% converts the divisions into un-numbered \texttt{TEI} |<div>|
% elements allowed to nest recursively and takes one mandatory
% argument in which the following |key-value| arguments are
% accepted:---\\
% \DescribeOption{type} |type|$=$\meta{name}
% \hfill\tcboxverb{Default: none}\\
% |type| corresponds to the \texttt{TEI} class |att.typed| and can be
% used to classify the element in which it is found in any
% way. Suitable values here can be |book|, |chapter|, |section| and
% the like.\\
% \DescribeOption{n} |n|$=$\meta{value} \hfill
% \tcboxverb{Default: none}\\

% As \texttt{TEI} un-numbered divisions are simply |<div>| elements

%
% \paragraph{Formatting the Titles}
% \DescribeMacro{\FormatDiv} By design, \pkg{ekdosis} does
% not format the titles. Instead, depending on what is needed for the
% edition text, \cs{FormatDiv}\marg{n}\marg{code
% before}\marg{code after} is provided to lay out the titles of any
% hierarchic depth of division. This command takes three mandatory
% arguments as follows: \meta{n}, which is the number referring to the
% particular depth of division to be formatted and some \LaTeX\
% commands to go before and after the title itself. The following
% example illustrates how the titles of the largest division can be
% printed horizontally centered in a larger size:---

% \subsection{Headers and Footers}
% \label{sec:headers-footers}
% \newfeature[v1.3] \pkg{ekdosis} provides a mechanism of its own for
% emitting header and footer marks. The first operation consists in
% recording the information to be printed as signpost by means of the
% |mark| optional argument of the \cs{ekddiv} command described above
% in \vref{sec:ekddiv}.
%
% \DescribeMacro{\ekdmark} Once this is done, \cs{ekdmark} can be
% inserted in commands used to make headers and footers where the mark
% is to be printed.
%
% A common layout is that of headers in which one finds printed in
% sequence on even pages the page number, then the author's name, and
% on odd pages the title of the edited text, then the current
% division, then the page number, like so:---
%
% \needspace{5\baselineskip}
% \begin{xltabular}{1.0\linewidth}{|XcX|}
%   \multicolumn{3}{l}{Even pages:}\\
%   \hline
%   \cs{thepage} & Hippocratis & \\
%   \hline
%   \multicolumn{3}{l}{Odd pages:}\\
%   \hline
%    & Epidemiarum liber II, \cs{ekdmark} & \hfill\cs{thepage}\\
%   \hline
% \end{xltabular}
%
% To return to the example provided by \vref{lst:ekddiv-ex}, the mark
% of the current division would be inserted in the third-level
% \cs{ekddiv} command printed at line~28 like so:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[firstnumber=28,linenos]{latex}
  \ekddiv{head=1, type=paragraph, depth=3, n=II.1.1, mark={1, 1}}
\end{minted}
% \iffalse
%</example>
% \fi
%
% The following example finally illustrates how the corresponding
% headers and footers can be prepared in a straightforward way with
% the help of the \pkg{titleps} package:\footcite{titleps}---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
% Preamble:

  \sethead[\thepage][Hippocratis][]
          {}{Epidemiarum liber II, \ekdmark}{\thepage}
}
% Apply the page style:
\pagestyle{edition}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \DescribeMacro{\endmark} It must be noted that \cs{ekdmark} is
% designed to print the first mark that is emitted on a given page and
% ignore the mark corresponding to any portion of text that may be
% printed between the top of the page and the point where the first
% mark is called. \cs{endmark} is an argument-less command that can be
% used just at the end of that portion of text to instruct
% \pkg{ekdosis} to print the last-emitted mark of the preceding page
% instead of the first-emitted mark of the current page.
%
% \paragraph{Removing Headers and Footers}
% Pages such as title pages must be printed with empty headers and
% footers. \pkg{ekdosis} must be given control over every item of
% information inserted in these areas beforehand.
%
% \DescribeMacro{\ekdprintmark}
% \cs{ekdprintmark}\marg{selector}\marg{signpost} The signposts
% printed in headers and footers must be passed as second argument of
% \cs{ekdprintmark} so that \pkg{ekdosis} can remove them on pages
% where printing them is not desirable. \meta{selector} refers to
% three symbolic letters where the first can be either |H| or
% |F|\===for \underLine{h}eader or \underLine{f}ooter\===, the second
% |E| or |O|\===for \underLine{o}dd or \underLine{e}ven\===and the
% third |L|, |C| or |R|\===for \underLine{l}eft, \underLine{c}enter or
% \underLine{r}ight. The example provided above would then read as
% follows:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
% Preamble:

          {}
          {\ekdprintmark{HOC}{Epidemiarum liber II, \ekdmark}}
          {\ekdprintmark{HOR}{\thepage}}
}
% Apply the page style:

\end{minted}
% \iffalse
%</example>
% \fi
%
% \paragraph{\enquote{Paired} facing pages}
% \phts\label{sec:header-paired-pages}
% As already described \vpageref{ref:paired-opt}\===the
% \textooquote|paired|\textcoquote\ option\===\pkg{ekdosis} can
% arrange texts on facing pages with every right-hand page number
% unchanged, so that both facing pages hold the same number, as in the
% \enquote{Budé} series. As a result of this layout, the distinction
% between left- and right-hand pages does not apply and headers and
% footers have to be set as if the whole edition text and the
% translation were intended for single-sided printing. To return to
% the example just given, the three optional arguments of \cs{sethead}
% are inoperative, as are the symbolic letters |E| and |O| of
% \cs{ekdprintmark}. Both letters must be omitted, which boils down to
% using the following six selectors, instead of twelve: |HL|, |HC|,
% |HR|, |FL|, |FC| and |FR|.
%
% \DescribeMacro{\ekdEOprint}\newfeature[v1.5] Finally, to make up for
% commands and arguments designed to set headers and footers on
% left-hand pages, \pkg{ekdosis} provides \cs{ekdEOprint}. This
% command accepts two mandatory, self-evident arguments, like so:
% \cs{ekdEOprint}\marg{left-hand mark}\marg{right-hand mark}.
%
% As an illustration, the example provided above would read as follows
% for editions laid out on \enquote{paired} facing pages:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
% Preamble:

          {\ekdprintmark{HR}{\ekdEOprint{}{\thepage}}}
}
% Apply the page style:

% \iffalse
%</example>
% \fi
%
% \paragraph{\enquote{Mirrored} paired facing pages}
% \newfeature[v1.5] The \textooquote|paired|\textcoquote\ option just
% described can give surprising results at first sight, in which
% facing pages are arranged by succeeding pairs of left- or right-hand
% pages. This is certainly not the desired layout for duplex
% printing. However, this is not a redhibitory inconvenience for
% professional printers can easily carry out the necessary corrections
% by applying offsets to the horizontal margins. That being said, one
% may also wish to have these horizontal offsets applied from the
% outset in the PDF output that is produced by \LaTeX.
%
% \danger What follows assumes that the critical edition is printed on
% facing pages and starts on a left-hand page. Furthermore, it must be
% noted that the |paired| option must be either unset or set to
% |false|.
%
% \DescribeMacro{\setpairedpage} \cs{setpairedpage} is provided to set
% mirrored paired facing pages. This command takes no argument and is

%   \cs{thepage}.
% \item If there be no \cs{thepage} in headers or footers,
%   \cs{setpairedpage} must still be issued once on each side.
% \end{remarks}
%
% \DescribeMacro{\setpairedpagenum} \cs{setpairedpagenum}\marg{number}

% 
% \section{The Tricks of the Trade}
% \label{sec:tricks-of-trade}
% As the |.tex| source file is compiled, \pkg{ekdosis} has to compute
% a tremendous amount of data. Most of this work is performed by
% \textsf{Lua} functions. An edition text narrowed down to a single
% page needs to be compiled at least three times. On the first run,
% the apparatus criticus does not show. Instead, \pkg{ekdosis}
% produces an auxiliary file named \cs{jobname}|.ekd| in which all the
% entries of the apparatus criticus are collected. Then, on the second
% run a test is performed on this auxiliary file to determine whether
% there are entries\---and if so, which ones\---to be printed on the
% current page. At the same time, references to the line numbers are
% updated if necessary. Finally, on the third run, the apparatus
% criticus is printed.
%
% Of course, every change made to the input may similarly require
% \hologo{LuaLaTeX} to be run three more times to get everything to
% the right place with the right numbers.
%
% \subsection{The Oscillating Problem}
% \label{sec:oscillating-problem}
% In some instances, notably when on a given page entries are very
% abundant in number, specifically when the edition text is getting
% close to the bottom of the page, \pkg{ekdosis} may oscillate
% indefinitely between different sets of page decisions without being
% able to settle down. The condition may be typically illustrated as
% follows: after Lua\LaTeX\ has been run, an entry is attached to the
% last line of the page. As said above, this entry does not show
% yet. But when it does, should it result in an additional line being
% printed in the apparatus criticus, the last line of the edition
% text\---the one the entry was previously attached to\---goes to the
% next page. As a result, this entry also moves to the next page with
% the line it belongs to. This point is literally critical, because
% unless a \cs{pagebreak} is inserted just here so as to keep the
% contentious line on the next page, \pkg{ekdosis} enters a vicious
% circle from which it cannot escape, not to mention that right
% entries with right line numbers cannot come on pages that follow a
% wrong page either.
%
% An alert reader may have guessed that inserting a \cs{pagebreak} is
% a good way to get out of the vicious circle. And surely, if only a
% few pages be at stake, this is the way to go. However,
% \cs{pagebreak} commands should only be inserted when the whole
% edition text is ready for any substantial change in the preceding
% pages may result in pages that break just after they begin.
%
% \paragraph{Conditional page breaks}
% \phts\label{ref:ekdpb} \DescribeMacro{\ekdpb}\DescribeMacro{\ekdpb*}
% \cs{ekdpb}\oarg{page no}\marg{line no}
% \cs{ekdpb*}|{}| \cs{ekdpb*}
% \newfeature[v1.2]\\
% One way to avoid this inconvenience is to use \cs{ekdpb} instead of
% the standard \cs{pagebreak} command provided by \LaTeX\ to insert
% conditional page breaks. \cs{ekdpb} takes as mandatory argument the
% line number, as it is printed in the margin, where the page break
% should take place. An optional argument allows to further specify
% the page number where the page break should occur. The value that is
% expected is the page number as it is printed\===e.g.\ an Arabic,
% Roman or alphanumeric number. If the specified conditions be not
% met, then the page break is not triggered.  Finally, the
% \enquote{starred} version of this command forces the page break,
% irrespective of the values specified as page or line numbers. Unlike
% \cs{ekdpb}, which requires the lines to be numbered, \cs{ekdpb*} is
% allowed at any point of the document: as \cs{ekdpb*} disregards the
% number given as argument, it is equivalent to the standard \LaTeX\
% \cs{pagebreak} command. Yet it can be used instead of the latter to
% have marks further printed in the margins so as to spot with a
% fleeting glance the locations where induced page breaks
% occur.\footnote{This requires the |showpagebreaks| option to be set
% to |true| as described above \vpageref{ref:showpagebreaks-opt}.}
%
% \paragraph{Using \texttt{maxentries}}
% Another way\---should the edition text fall into the vicious circle
% too often\---is to limit the number of entries per page that all
% layers of critical notes taken together or a given layer of
% apparatus criticus may accept as described above on
% pages~\pageref{ref:glimit} and~\pageref{ref:maxentries}. As a result,
% \pkg{ekdosis} will take care of inserting automatic breakpoints
% between pages whenever the number of entries on a given page reaches
% the value set as |maxentries|.
%
% |maxentries| must not be too small: otherwise offensive to look at
% vertical spaces may come between the edition text and the apparatus
% criticus. Conversely, |maxentries| must not be too big: otherwise,
% should entries overflow on a given page, the edition text and the
% apparatus criticus may clash again. As said above, a couple of
% clashes can be managed with a couple of manually inserted page
% breaks. But if there be too many of them, it is a good indication
% that the selected value of |maxentries| is too high.
%
% Complex edition texts do have a magic number. An advisable way to
% figure it out would be to start from a sample of only a few pages,
% selected as evidence for the complexity of the whole. As only a few
% pages would need to be compiled, the magic number should emerge
% quite rapidly.
%
% \paragraph{Adding and Removing Entries}
% \DescribeMacro{\addentries} \cs{addentries}\oarg{layer}\marg{n}
% \newfeature[v1.1]\\
% If |maxentries| be set for a given layer of critical notes,
% \cs{addentries}\oarg{layer}\marg{n}, where \meta{n} is an integer,
% can be used to add \meta{n} to\---or remove it from if \meta{n} be
% negative\---the number of accepted entries on the current
% page. \cs{addentries} operates on the default layer of notes, but
% any other declared layer can be specified in the optional argument
% of the command.
%
% \danger Of course, \cs{addentries} must be issued before the
% number of entries on a given page has reached the value set as
% |maxentries|.
%
% Once a sensible value for |maxentries| has been found,
% \cs{addentries} can further be used with a positive integer to allow
% for more entries and more lines on some pages so that offending
% vertical spaces are decreased. Conversely, \cs{addentries} with a
% negative integer will remove entries on pages where there are too
% many of them and \pkg{ekdosis} still oscillates between different
% sets of page decisions.
%
% \paragraph{The \texttt{fitapp} Global Option}
% \newfeature[v1.3] The rationale of this option is discussed above
% (see \vref{ref:fitapp-opt}). As this mechanism has the characters of
% the apparatus block scaled down to allow for more entries once a
% predefined height has been reached, \pkg{ekdosis} should settle down
% in most of the contentious cases.\footnote{That is, cases that arise
% \emph{after} the predefined height has been reached.} However, it is
% advisable to use |fitapp| conjointly with |maxentries| to prevent
% the number of allowed entries from being too high, which would
% result in the characters being too small or even illegible.
%
% \subsection{Using \textsf{emacs}}
% \label{sec:using-emacs}
% \pkg{ekdosis} includes an AUC\TeX\ style file that can be used to
% facilitate the insertion of the many commands it provides.
%
% \paragraph{Installation}
% In what follows, it is assumed that both the \textsf{emacs} text
% editor\footnote{\url{https://www.gnu.org/software/emacs}} and

%   \end{enumerate}
% \item[\pkg{ekdosis} Development Version]
%   \begin{enumerate}
%   \item Download |ekdosis.el| from either
%     |git.robertaless|\allowbreak|i.net|
%     (\url{http://git.robertalessi.net/ekdosis/plain/ekdosis.el})
%     or the |sourcehut| git
%     repository
%     (\url{https://git.sr.ht/~ralessi/ekdosis/blob/master/ekdosis.el}).
%   \item Copy this file to
%     |$HOME/.emacs.d/auctex/auto/|\useFN\fnAUCTeX\ where |$HOME|
%     stands for the directory of the current user.
%   \end{enumerate}
% \end{description}
%
% If desired, |ekdosis.el| can be compiled like so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{bash}
emacs --batch -f batch-byte-compile ekdosis.el &>/dev/null
\end{minted}
% \iffalse
%</example>
% \fi
%
% This will produce |ekdosis.elc| which can be copied to the same
% directory as |ekdosis.el|.
%
% \paragraph{Code Folding}
% \phts\label{ref:code-folding}
% The variant readings and the critical notes can grow in number to a
% point where they may clutter the source text. As a result, the
% edition text can become illegible. One way around this difficulty is
% to use the \textsf{emacs} editor with |ekdosis.el|, the AUC\TeX\
% style file that is provided with \pkg{ekdosis}, to fold the code so
% that only the edition text, exclusive of variants and notes, is
% displayed on the screen.
%
% In order to hide all foldable items, |TeX-fold-mode| must first be
% activated, like so: |C-c| |C-o| |C-f|.\footnote{Menu sequence:
% \menu{LaTeX>Show/Hide>Fold Mode}} Then |C-c| |C-f| |C-b| can be used
% to fold the code.\footnote{Menu sequence: \menu{LaTeX>Show/Hide>Hide
% All in Current Buffer}}
%
% \DescribeMacro{\App}
% \newfeature[v1.5]\cs{App}|[type=|\meta{type}|]|\marg{lemma
% text}\marg{readings and notes}\phts\label{ref:App-cmd}\\
% \cs{App} allows for much more flexible code folding where notes and
% variants are hidden to let only the base text appear on the screen.
% \cs{App} is strictly equivalent to \cs{app}, except that the
% apparatus entries are meant to be distributed in two different
% arguments, like so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}
I saw my friend \App{\lem{Peter}}{\rdg{John}} yesterday.
or:
I saw my friend \App{\lem{Peter}}{+\label{ln:App:1}+
    \rdg{John}
  } yesterday.+\label{ln:App:2}+
\end{minted}
% \iffalse
%</example>
% \fi
%
% \begin{remarks}
% \item As can be seen, the first argument of \cs{App} is meant to
%   receive the lemma text while \cs{rdg}, \cs{note} and the like are
%   inserted in the second one.
% \item As the second argument of \cs{App} is the foldable item, a
%   good practice is to keep the lemma text on the same line as the
%   opening brace (l.~\lnref{ln:App:1}) and to write the continuation
%   of the text just after the closing brace (l.~\lnref{ln:App:2}).
% \end{remarks}
% 
% Code folding, once applied, results in a clean source text with no
% clutter as follows:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[escapeinside=++]{latex}
I saw my friend +\textcolor{lavender}{Peter}+ yesterday.
\end{minted}
% \iffalse
%</example>
% \fi
% 
% \danger As there is no point in using this command for anything
% other than this specific purpose, \cs{app} is used in the examples
% throughout this document.
% 
% \subsection{Variae Quaestiones}
% \label{sec:variae-quaestiones}
% This section is about issues that are not strictly speaking part of
% the documentation of \pkg{ekdosis} but may nevertheless
% circumstantially arise.
%
% \paragraph{Superfluous Dots}
% \phts\label{sec:superfluous-dots} As said above
% \vpageref{ref:ending-dot}, it is customary in some editions to have
% a full stop printed at the end of the apparatus
% criticus. \pkg{ekdosis} provides specific commands to achieve this
% in a straightforward way, such as \cs{SetEndApparatus} and the
% |ehook| optional argument of \cs{SetApparatus} and
% \cs{DeclareApparatus}.\footnote{See above
% \vpagerefrange{ref:setendapparatus}{sec:declaring-layers}.} However,
% if the last word of the apparatus criticus on a given page be an
% abbreviation followed by a dot, such a setting will have two dots
% printed at the end of the apparatus instead of one. The solution is
% to define a command to have a dot printed only if not followed by a
% dot, and append this command to the abbreviated form of the word,
% like so:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}{latex}
% Preamble:
\usepackage{xspace}
\usepackage{ekdosis}

\makeatletter
\newcommand{\ekddot}{%
  \ltx@ifnextchar@nospace{.}{\xspace}{.\xspace}}
\makeatother

\DeclareApparatus{default}[ehook=.]
\DeclareScholar{Erm}{Erm\ekddot}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \begin{remarks}
% \item Line~2: The \pkg{xspace} package is needed for \cs{xspace} is
%   used by the \cs{ekddot} command that is defined at l.~6.
% \item Line~7: \cs{ltx@ifnextchar@nospace} is part of the
%   \pkg{ltxcmds} package which is loaded by \pkg{ekdosis}. As this
%   command uses a private control sequence, it must be found within
%   \cs{makeatletter} \dots\ \cs{makeatother}.
% \item Line~10: \cs{ekddot} will only work with multiple-layer
%   apparatus criticus. Therefore, |\DeclareAppa|\allowbreak|ratus|
%   must be used even if only one layer of critical notes be needed.
% \end{remarks}
%
% \paragraph{Backup of Essential Files}
% Each time the |.tex| source file is compiled, \pkg{ekdosis} reads
% the |.aux| corresponding \LaTeX\ auxiliary file and its own |.ekd|
% auxiliary file so as to process labels and collect entries of the
% apparatus criticus. If for whatever reason\---e.g.\ some unknown
% command has been inserted\---the compilation be frozen and so must
% be aborted, it may happen that most of the edition text has to be
% reconstructed page after page. For large and complex editions, this
% makes advisable to have current versions of those files backed up
% each time a new compilation begins, which can be achieved by
% inserting the following lines before the line that loads the
% document class:---
% 
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\RequirePackage{verbatimcopy}
\IfFileExists{\jobname.aux}{%
  \OldVerbatimCopy{\jobname.aux}{\jobname.aux.bak}}{}
\IfFileExists{\jobname.ekd}{%
  \OldVerbatimCopy{\jobname.ekd}{\jobname.ekd.bak}}{}
\documentclass{book}
\end{minted}
% \iffalse
%</example>
% \fi
%
% This way, both |.aux| and |.ekd| files can be recovered from
% |.aux.bak| and |.ekd.bak| just after the compilation has been
% aborted. Should this be needed, one must proceed carefully as
% follows:---
% \begin{enumerate}
% \item Just after the compilation has been aborted, move both
%   |aux.bak| and |ekd.bak| files to a safe place.
% \item Remove or correct the offending command or lines that broke
%   the compilation and make sure that the issue is solved.
% \item Restore the |.aux| and |.ekd| files from |aux.bak| and
% |.ekd.bak| and resume work where it was left off.
% \end{enumerate}
%
% \section{\texttt{TEI xml} Output}
% \label{sec:teixml-output}
% Several examples of \texttt{TEI xml} output have been provided
% hitherto. Before proceeding, the reader is invited to return to
% every one of them. In this respect, it may be of interest to review
% carefully the excerpt of Caesar's \emph{Gallic War} of which the
% \LaTeX\ source file and its corresponding \texttt{TEI xml} output
% are printed in full below in \vref{sec:caesar-gw-6-1-13}. Once
% \pkg{ekdosis} has been instructed to convert the edition text into
% \texttt{TEI xml} (l.~11), the preamble of this file shows how to set
% languages and fonts to be used in the document (ll.~2--6), format
% the titles (l.~16) and lay out the alignment of an edition text
% associated with two translations (ll.~18--25) in modern
% languages. Furthermore, it shows how information related to each
% language (Latin, English and French) is to be found in two different
% places, namely for \texttt{TEI xml} output (ll.~21--3) and for PDF
% output through \LaTeX\ (ll.~27--9). Finally, it provides examples of
% declaring witnesses, hands and shorthands (ll.~31--60). As to the
% document itself, it shows how to lay out a conspectus siglorum in a
% table (ll.~64--80), before giving detailed examples of how the
% edition text is entered (ll.~85--101) and sectional commands
% provided by \pkg{ekdosis} are used (ll.~86, 103 and
% 110).\footnote{The PDF output is available as
% \href{samples/Caesar_BG-6-13-1.pdf}{a separate file}.}
%
% \subsection{Requesting \texttt{TEI xml} Output}
% \label{sec:request-tei-output}
% \texttt{TEI xml} output is requested by means of the |teiexport|
% global option as described above
% \vpageref{ref:teiexport-option}. Once instructed to output
% \texttt{TEI}, \pkg{ekdosis} converts and exports in sequence the
% contents of \env{ekdosis} environments (see above
% \vref{sec:single-text-editing}). As regards the contents of
% \env{alignment} environments (see above \vref{sec:alignment-basic}),
% \pkg{ekdosis} first collates the contents of the environments that
% have been declared as values of the |texts| optional argument of
% \env{alignment} or \cs{SetAlignment},\footnote{See above
% \vref{sec:multiple-alignment}.} then places each of the
% corresponding \texttt{TEI xml} outputs within distinct |<div>|
% elements named after the declared environments themselves. For
% example, to return to Caesar's text, the Latin edition text is found
% between a \cs{begin}|{latin}| \dots\ \cs{end}|{latin}| environment
% (see the |.tex| source file, \vref{sec:caesar-gw-tex}, ll.~85--101)
% which is declared at l.~21. Then, the corresponding \texttt{xml}
% output is found within a |<div>| element, the |xml:id| of which has
% been given by \pkg{ekdosis} the value |div-latin_1| (see
% \vref{sec:caesar-gw-tei}, ll.~176--200).
%
% \paragraph{\texttt{TEI} File Name} \DescribeMacro{\SetTEIFilename}
% \cs{SetTEIFilename}\marg{basename} is a preamble-only command. It
% can be used to set the base name of the \texttt{TEI xml} output
% file, to which the suffix |.xml| is appended. By default, the base
% name is \cs{jobname}|-tei|.
%
% \subsection{General Principles}
% \label{sec:totei-general-principles}
% \paragraph{Validation of the \texttt{TEI xml} Structure}
% The reference tool that the author relies on is that provided by the
% \emph{\texttt{TEI} by Example Project}.\footnote{\cite{TBE}.
% The \texttt{TEI} validator is here:
% \url{http://teibyexample.com/xquery/TBEvalidator.xq}.} As for
% \pkg{ekdosis}, it is designed to produce on request, in addition to
% an edition in print, a \texttt{TEI xml}-compliant output file. That
% said, one must keep in mind that the \LaTeX\ packages that are part
% of {\TeX}Live can be counted in thousands, and the commands they
% provide in tens of thousands. There may even be grounds in asserting
% that the possibilities offered by \TeX\ and \LaTeX\ quite exceed
% what can be afforded by \texttt{TEI xml}. On another hand, many
% \LaTeX\ commands make no sense in \texttt{TEI}. Therefore, a
% sensible choice is to keep them out of the environments the contents
% of which are to be translated into \texttt{xml} elements, as will be
% illustrated by the following.
% 
% Converting a \LaTeX\ document into \texttt{TEI xml} can be quite an
% intricate business. In many cases, however, \LaTeX\ strings are
% found within environments or groups that are easy to convert into
% \texttt{TEI} equivalents: unless instructed otherwise, whether such
% groups are delimited by opening and closing braces or by explicit
% \cs{begin} \dots\ \cs{end} commands, \pkg{ekdosis} translates them
% into |xml| so that for example \cs{emph}|{word}| and
% \cs{begin}|{quote}| \meta{quoted words} \cs{end}|{quote}| become
% |<emph>| \meta{word} |</emph>| and |<quote>| \meta{quoted words}
% |</quote>| respectively.
%
% But \LaTeX\ does not place everything into groups or
% environments. To take here but a few examples, sectional divisions
% are marked in \LaTeX\ with \enquote{open} commands such as
% \cs{chapter} or \cs{section} with no clear indication where the
% closure of divisions occurs, contrary to \texttt{TEI xml} markup
% with numbered or un-numbered |<div>| elements allowed to nest
% recursively. As regards running paragraphs of text, the situation is
% even worse than in the latter case, as the following simple example
% shows:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}{latex}
\begin{document}
\begin{ekdosis}
  ...

  ... These are the final words of some section in the body text.

  \section{New Section}

  Here is how some new section begins...

  ... Final words.
  \section{Other Section}
  Opening words of the section...
  
  ... Final words
  
  \section{Other Section}
  Opening words...
  
  ... Final words.
\end{ekdosis}
\end{document}
\end{minted}
% \iffalse
%</example>
% \fi
%
% Obviously, construing this \LaTeX\ source file into \texttt{TEI xml}
% is a fairly complex task. For example, line~6 only closes a
% paragraph for line~7 opens a division (hence |</p><div1>|), line~8
% only opens a paragraph just after the heading of the section (hence
% |</head><p>|) while line~14 both closes the foregoing paragraph and
% opens a new one (hence |</p><p>|), contrary to line~16 which both
% closes a paragraph and a sectional division (hence |</p></div1>|),
% not to mention lines~20--1, where notwithstanding the absence of
% blank line or any other indication,
% |</p></div1></body></text></TEI>| is needed.
%
% \pkg{ekdosis} has been designed to implement this task through
% \textsf{Lua} functions which involve string matching (both forward
% and reverse matching) and recursions.
%
% \paragraph{\texttt{TEI xml} Export Settings}
% \label{ref:setteixmlexport}
% \DescribeMacro{\SetTEIxmlExport} \cs{SetTEIxmlExport}\marg{csv list
% of options} can be used in the preamble or at any point of the
% document, except inside environments set to receive an apparatus
% criticus, namely the \env{ekdosis} environment or any other similar
% environment declared by means of the \env{alignment} environment or
% \cs{SetAlignment}.\footnote{See above
% \vref{sec:multiple-alignment}.}  At the time of writing, there is
% only one option, as follows:---\\
% \DescribeOption{autopar} |autopar|$=$\verb+true|false+
% \hfill\tcboxverb{Default: true}\\
% The algorithm described above applies for edition texts composed in
% running paragraphs or lines of poetry, but it may fail to produce a
% valid \texttt{TEI xml} output with other arrangements, such as
% performance texts or transcriptions of speech for which the
% \texttt{TEI} Guidelines define specific rules.  |autopar=false|
% instructs \pkg{ekdosis} to ignore blank lines in the |.tex| source
% file as markers for paragraph boundaries. As a result, each
% paragraph of the edition text must be found within an environment
% associated with the \texttt{xml} element |<p>|, such as \env{ekdpar}
% or any other environment declared as such by means of \cs{EnvtoTEI}
% described below in \vref{sec:new-cmds-envs}. A typical use case of
% |autopar=false| is provided below in
% \vref{sec:specific-tei-modules}.
%
% \DescribeEnv{ekdpar} \cs{begin}|{ekdpar}| \dots\ \cs{end}|{ekdpar}|
% is a simple environment that does nothing but insert \cs{par}
% primitives. It can be used to instruct \pkg{ekdosis} to place
% paragraphs within |<p>| elements when |autopar| has been set to
% |false| by means of \cs{SetTEIxmlExport} described above.
%
% \paragraph{The \texttt{xml:id} Attribute}
% \phts\label{ref:xmlid} As a general rule, the |xml:id| global
% attribute must be unique for the element that bears the
% attribute. Furthermore, it must begin with a letter or an underscore
% and contain no characters other than letters of the Latin
% alphabet\--- from |a| to |z|, either upper or lower case\---digits,
% hyphens, underscores and full stops. \pkg{ekdosis} issues a warning
% when it finds that any \meta{unique id} of \meta{unique label}
% expected in the first argument of \cs{DeclareWitness},
% \cs{DeclareHand}, \cs{DeclareSource} or \cs{DeclareScholar} is not
% unique or breaks the rules just described, but does not prevent the
% |.tex| source file from compiling. Instead, it prints the string
% |<??>| in place of the expected formatted siglum so that the error
% in the |.tex| source file can be easily spotted and corrected.
%
% \danger As the \meta{unique id} declared with \cs{DeclareShorthand}
% is not to be exported in the \texttt{TEI xml} output file,
% \pkg{ekdosis} checks neither its uniqueness nor its validness.
%
% \danger It must be noted that \LaTeX\ labels that are provided in
% commands such as \cs{label}, \cs{cite} and the like must also be
% unique in the document. As \LaTeX\ will issue warnings if duplicates
% be found, \cs{ekdosis} does not check their uniqueness but will
% issue warnings if such labels contain invalid strings.
%
% \subsection{Routine \LaTeX\ Commands and Environments}
% \label{sec:routine-cmds}
% The list of \LaTeX\ commands known by \pkg{ekdosis} at the time of
% writing follows. To this list must be added the \LaTeX\ standard
% commands that are used for sectional divisions as described above in
% \vref{sec:latex-divs} and most of the commands provided by the
% \pkg{arabluatex} and \pkg{icite}\footcite{icite} packages. Standard
% citation commands are also supported as will be described below in
% \vref{sec:citation-cmds}:---
% 
% \begin{xltabular}{0.825\linewidth}{XX}
%     \toprule
%     \LaTeX\ command & \texttt{TEI xml} element\\
%     \midrule\endhead

%     \cs{--} or \cs{==} & -- \\
%     \cs{-/} or \cs{=/} & ‐ \\
%     \bottomrule
% \end{xltabular}
%
% As for environments:---
% 
% \begin{xltabular}{0.825\linewidth}{XX}
%     \toprule
%     \LaTeX\ environment & \texttt{TEI xml} element\\
%     \midrule\endhead

%     |quoting| & |<quote></quote>| \\
%     |verse| & |<lg></lg>| \\
%     \bottomrule
% \end{xltabular}
%
% Regarding other, very frequently used commands or environments, some
% do not need to be inserted in the translation tables: as already
% said above, \pkg{ekdosis} converts by default the original names of
% these into \texttt{xml} elements. For instance, \cs{emph}|{}| and
% \cs{begin}|{quote}| \dots\ \cs{end}|{quote}| will result in
% |<emph></emph>| and |<quote></quote>| respectively.
%
% For the same simple reason, should one wish to have words within a
% \texttt{TEI xml} element that does not have any \LaTeX\ equivalent,
% all is needed is to define an inoperative \LaTeX\ command named
% after the \texttt{TEI} element, like so:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
% Preamble:
\newcommand{\mentioned}[1]{#1}

% Document:

Our usage corresponds to the \mentioned{aggregate} of many
mathematical writings and to the sense of \mentioned{class} found in
older logical writings.
\end{minted}
% \iffalse
%</example>
% \fi
%
% \texttt{TEI xml} output:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{xml}
<p>Our usage corresponds to the <mentioned>aggregate</mentioned> of
many mathematical writings and to the sense of
<mentioned>class</mentioned> found in older logical writings.</p>
\end{minted}
% \iffalse
%</example>
% \fi
%
% Of course, it is also possible to have the \enquote{mentioned} words
% printed in a different font family:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
\newcommand{\mentioned}[1]{\textsf{#1}}
\end{minted}
% \iffalse
%</example>
% \fi
%
% This command will print them in a sans serif font family, with the
% exact same \texttt{TEI xml} output as above.
%
% \subsection{Processing New Commands or Environments}
% \label{sec:new-cmds-envs}
% The following three commands are provided to instruct \pkg{ekdosis}
% how to convert unknown or unusual \hologo{(La)TeX} commands or
% environments into \texttt{TEI xml} equivalents.
%
% \DescribeMacro{\TeXtoTEI} \cs{TeXtoTEI}\marg{csname}\marg{TEI
% element}\oarg{TEI attribute(s)}\\
% \cs{TeXtoTEI} takes two mandatory arguments and one optional
% argument, namely: the control sequence name to be converted, the
% \texttt{TEI} element it is to be converted into and any additional
% \texttt{xml} attributes to be appended to the opening \texttt{TEI}
% element. For example, the \cs{sidenote} command that is provided by
% the \pkg{sidenotes} package can be processed like so:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{latex}
% Preamble:
\TeXtoTEI{sidenote}{note}[place="margin"]

% Document:

      break}\footnote{The turning point of the poem...}
  \end{ekdverse}
\end{ekdosis}
\end{minted}
% \iffalse
%</example>
% \fi
%
% \texttt{TEI xml} output:---
%
% \iffalse
%<*example>
% \fi
\begin{minted}[linenos=false]{xml}
<lg>
  <l>The self-same moment I could pray;
  <note place="margin">The spell begins to break</note>
  <note place="bottom">The turning point of the
  poem...</note></l>
</lg>
\end{minted}
% \iffalse
%</example>
% \fi
%
% Even more subtly, provided that the code |#STC| points to some more
% information identifying the agency concerned:\footnote{At the time
% of writing, \enquote*{sources} can be declared with
% \cs{DeclareSource} as described above
% \vpageref{ref:declare-source}. Then the unique identifier used in
% the first argument of this command can point to the list of
% references inserted by \pkg{ekdosis} in the back matter section of
% the \texttt{TEI} output file. See below
% \vref{sec:references-cited-works} for more information on how to do
% this. Scholars can also be referred to as individuals by means of

% Finally, this more flexible\---and more delicate to
% handle\---command uses pattern matching to instruct \pkg{ekdosis}
% how to convert \hologo{(La)TeX} commands into \texttt{TEI}
% equivalents. In the first mandatory argument, strings to be captured
% are marked in sequence with numbers prefixed by |#|, like so: |#1|,
% |#2|, |#3| and so forth. Then, in the second mandatory argument, the
% strings captured are inserted where each of them is expected in
% the \texttt{TEI} element.
%
% \danger If the entire string to be captured be enclosed in square or
% curly brackets, it is advisable to use |@b|\texttt{\emph{n}} (for
% curly brackets) or |@s|\texttt{\emph{n}} (for square brackets)
% instead of |#|\texttt{\emph{n}}, where \texttt{\emph{n}} is the
% number that is expected in the sequence. This will prevent any
% brackets that may be found in the captured string from being
% interpreted.
%
% \danger Strings must be entered exactly as \pkg{ekdosis} will find
% them as the |.tex| source file is compiled. Specifically,
% \emph{control sequences}, namely the coded commands immediately
% preceded by `\verb+\+' are always found followed by a space. For
% instance, |\emph{}| will be seen and processed by \pkg{ekdosis} as
% \verb*|\emph {}|.

% may be useful to retrieve the |xml| formatted pointers corresponding

% \cs{DeclareWitness}\footnote{See above
% \vpageref{ref:declarewitness}.} and the like so as to insert them in
% the second argument\===\meta{TEI pattern}\===of \cs{TeXtoTEIPat}. As
% an illustration, what follows creates a new \LaTeX\ command
% \cs{witStart} which prints nothing in the PDF ouput but inserts
% |<witStart/>| elements in the \texttt{TEI xml} file. This commands
% accepts an optional argument to make clear which are the fragmentary

% \item As can be seen from l.~\lnref{ln:getxml:a}, \cs{getTEIxmlid}
%   is used to process the csv-list of unique identifiers that matches
%   the string captured between the braces after |wit=|, as implied by
%   |@b1|. As a consequence, \cs{witStart}|[]| is expected as follows:
%   \mintinline{latex}|\witStart[wit={X,Y}]|. Braces must exist for

% \subsection{References to Cited Works}
% \label{sec:references-cited-works}
% A full example of what is technically called a \emph{Conspectus
% Siglorum} can be found above in \vref{sec:print-witnesses}. Such a
% list of manuscript sigla should be found immediately before the
% edition text. Traditionally, this section is followed by a list of
% other sources used to establish the text, so that the edited text is
% in the end established both from manuscript evidence (the
% \enquote{witnesses}) and other works based on a scholarly approach
% of the text (the \enquote{sources}) which are called in Latin
% \emph{Editiones uel Studia}. As a consequence of this classification
% as \enquote{witness} or \enquote{source}, the former must go within
% the |<listWit>| element of the \texttt{TEI} header, whereas the
% latter is to be found within the |<listBibl>| element.
%
% \DescribeMacro{\AddxmlBibResource}
% \cs{AddxmlBibResource}\marg{basename or name.xml} is a preamble-only

% \subsection{Citation Commands}
% \label{sec:citation-cmds}
% \pkg{ekdosis} can also convert into \texttt{TEI xml} references to
% cited works. Depending on the optional arguments used in the
% citation command, references will be converted into |<ptr>| or
% |<bibl>| elements with the appropriate identifier supplied by means
% of the |target| or |corresp| attributes.
%
% Of course, for this mechanism to work, Bib\TeX\ or Bib\LaTeX\ must
% be used and connected to some |.bib| bibliographical database
% file. Additionally, this |.bib| file must have been converted into a
% \texttt{TEI xml}-compliant file where all the Bib\hologo{(La)TeX}
% entries that are used in the document are found within
% |<biblStruct>| elements.\footnote{See above n.~\vref{fn:zotero} for

% \section{Future Work}
% \label{sec:future-work}
% A short, un-commented list of what is planned in the versions of
% \pkg{ekdosis} to come follows:---
% \begin{enumerate}
% \item Very short-term (weeks):---
%   \begin{enumerate}
%   \item Text structure: milestone elements.
%   \item Marginal edition texts: It may happen that the marginalia of
%     manuscripts contain texts worth editing in addition to and along
%     the main text to which they are linked by reference signs.
%   \end{enumerate}
% \item Short-term (months):---
%   \begin{enumerate}
%   \item Poetry: \pkg{ekdosis} is now able to load and use the
%     facilities provided by the \pkg{verse} package. Refined options
%     will be added, such as metrical analysis.  Arabic poetry through
%     the environments and commands provided by the \pkg{arabluatex}
%     package will also be supported. Other packages will also be
%     considered for inclusion, such as \pkg{poetry} or
%     \pkg{teubner}. In the end, \pkg{ekdosis} will provide a way for
%     the typesetting of poetry which will allow for more flexibility
%     and compatibility with \texttt{TEI xml}.
%   \item Correspondence and alignment, segmentation: The functions
%     are being tested at the time of writing and will be included in
%     \pkg{ekdosis}.
%   \end{enumerate}
% \item Medium-term: Indexing, commands and environments for specific
%   modules of the \texttt{TEI}.

% \begin{center}
%   {\bf\large Preamble}
% \end{center}
% 
% The purpose of this License is to make a manual, textbook, or other
% functional and useful document \enquote{free} in the sense of
% freedom: to assure everyone the effective freedom to copy and
% redistribute it, with or without modifying it, either commercially
% or noncommercially.  Secondarily, this License preserves for the
% author and publisher a way to get credit for their work, while not
% being considered responsible for modifications made by others.
% 
% This License is a kind of \enquote{copyleft}, which means that
% derivative works of the document must themselves be free in the same
% sense.  It complements the GNU General Public License, which is a
% copyleft license designed for free software.
% 
% We have designed this License in order to use it for manuals for
% free software, because free software needs free documentation: a
% free program should come with manuals providing the same freedoms
% that the software does.  But this License is not limited to software
% manuals; it can be used for any textual work, regardless of subject
% matter or whether it is published as a printed book.  We recommend
% this License principally for works whose purpose is instruction or
% reference.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 1. APPLICABILITY AND DEFINITIONS\par}
% \end{center}
% 
% This License applies to any manual or other work, in any medium,
% that contains a notice placed by the copyright holder saying it can
% be distributed under the terms of this License.  Such a notice
% grants a world-wide, royalty-free license, unlimited in duration, to
% use that work under the conditions stated herein.  The
% \enquote{\textbf{Document}}, below, refers to any such manual or
% work.  Any member of the public is a licensee, and is addressed as
% \enquote{\textbf{you}}.  You accept the license if you copy, modify
% or distribute the work in a way requiring permission under copyright
% law.
% 
% A \enquote{\textbf{Modified Version}} of the Document means any work
% containing the Document or a portion of it, either copied verbatim,
% or with modifications and/or translated into another language.
% 
% A \enquote{\textbf{Secondary Section}} is a named appendix or a
% front-matter section of the Document that deals exclusively with the
% relationship of the publishers or authors of the Document to the
% Document's overall subject (or to related matters) and contains
% nothing that could fall directly within that overall subject.
% (Thus, if the Document is in part a textbook of mathematics, a
% Secondary Section may not explain any mathematics.)  The
% relationship could be a matter of historical connection with the
% subject or with related matters, or of legal, commercial,
% philosophical, ethical or political position regarding them.
% 
% The \enquote{\textbf{Invariant Sections}} are certain Secondary
% Sections whose titles are designated, as being those of Invariant
% Sections, in the notice that says that the Document is released
% under this License.  If a section does not fit the above definition
% of Secondary then it is not allowed to be designated as Invariant.
% The Document may contain zero Invariant Sections.  If the Document
% does not identify any Invariant Sections then there are none.
% 
% The \enquote{\textbf{Cover Texts}} are certain short passages of
% text that are listed, as Front-Cover Texts or Back-Cover Texts, in
% the notice that says that the Document is released under this
% License.  A Front-Cover Text may be at most 5 words, and a
% Back-Cover Text may be at most 25 words.
% 
% A \enquote{\textbf{Transparent}} copy of the Document means a
% machine-readable copy, represented in a format whose specification
% is available to the general public, that is suitable for revising
% the document straightforwardly with generic text editors or (for
% images composed of pixels) generic paint programs or (for drawings)
% some widely available drawing editor, and that is suitable for input
% to text formatters or for automatic translation to a variety of
% formats suitable for input to text formatters.  A copy made in an
% otherwise Transparent file format whose markup, or absence of
% markup, has been arranged to thwart or discourage subsequent
% modification by readers is not Transparent.  An image format is not
% Transparent if used for any substantial amount of text.  A copy that
% is not \enquote{Transparent} is called \enquote{\textbf{Opaque}}.
% 
% Examples of suitable formats for Transparent copies include plain
% ASCII without markup, Texinfo input format, LaTeX input format, SGML
% or XML using a publicly available DTD, and standard-conforming
% simple HTML, PostScript or PDF designed for human modification.
% Examples of transparent image formats include PNG, XCF and JPG.
% Opaque formats include proprietary formats that can be read and
% edited only by proprietary word processors, SGML or XML for which
% the DTD and/or processing tools are not generally available, and the
% machine-generated HTML, PostScript or PDF produced by some word
% processors for output purposes only.
% 
% The \enquote{\textbf{Title Page}} means, for a printed book, the
% title page itself, plus such following pages as are needed to hold,
% legibly, the material this License requires to appear in the title
% page.  For works in formats which do not have any title page as
% such, \enquote{Title Page} means the text near the most prominent
% appearance of the work's title, preceding the beginning of the body
% of the text.
% 
% The \enquote{\textbf{publisher}} means any person or entity that
% distributes copies of the Document to the public.
% 
% A section \enquote{\textbf{Entitled XYZ}} means a named subunit of
% the Document whose title either is precisely XYZ or contains XYZ in
% parentheses following text that translates XYZ in another language.
% (Here XYZ stands for a specific section name mentioned below, such
% as \enquote{\textbf{Acknowledgements}},
% \enquote{\textbf{Dedications}}, \enquote{\textbf{Endorsements}}, or
% \enquote{\textbf{History}}.)  To \enquote{\textbf{Preserve the
% Title}} of such a section when you modify the Document means that it
% remains a section \enquote{Entitled XYZ} according to this
% definition.
% 
% The Document may include Warranty Disclaimers next to the notice
% which states that this License applies to the Document.  These
% Warranty Disclaimers are considered to be included by reference in
% this License, but only as regards disclaiming warranties: any other
% implication that these Warranty Disclaimers may have is void and has
% no effect on the meaning of this License.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 2. VERBATIM COPYING\par}
% \end{center}
% 
% You may copy and distribute the Document in any medium, either
% commercially or noncommercially, provided that this License, the
% copyright notices, and the license notice saying this License
% applies to the Document are reproduced in all copies, and that you
% add no other conditions whatsoever to those of this License.  You
% may not use technical measures to obstruct or control the reading or
% further copying of the copies you make or distribute.  However, you
% may accept compensation in exchange for copies.  If you distribute a
% large enough number of copies you must also follow the conditions in
% section~3.
% 
% You may also lend copies, under the same conditions stated above,
% and you may publicly display copies.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 3. COPYING IN QUANTITY\par}
% \end{center}
% 
% If you publish printed copies (or copies in media that commonly have
% printed covers) of the Document, numbering more than 100, and the
% Document's license notice requires Cover Texts, you must enclose the
% copies in covers that carry, clearly and legibly, all these Cover
% Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
% the back cover.  Both covers must also clearly and legibly identify
% you as the publisher of these copies.  The front cover must present
% the full title with all words of the title equally prominent and
% visible.  You may add other material on the covers in addition.
% Copying with changes limited to the covers, as long as they preserve
% the title of the Document and satisfy these conditions, can be
% treated as verbatim copying in other respects.
% 
% If the required texts for either cover are too voluminous to fit
% legibly, you should put the first ones listed (as many as fit
% reasonably) on the actual cover, and continue the rest onto adjacent
% pages.
% 
% If you publish or distribute Opaque copies of the Document numbering
% more than 100, you must either include a machine-readable
% Transparent copy along with each Opaque copy, or state in or with
% each Opaque copy a computer-network location from which the general
% network-using public has access to download using public-standard
% network protocols a complete Transparent copy of the Document, free
% of added material.  If you use the latter option, you must take
% reasonably prudent steps, when you begin distribution of Opaque
% copies in quantity, to ensure that this Transparent copy will remain
% thus accessible at the stated location until at least one year after
% the last time you distribute an Opaque copy (directly or through
% your agents or retailers) of that edition to the public.
% 
% It is requested, but not required, that you contact the authors of
% the Document well before redistributing any large number of copies,
% to give them a chance to provide you with an updated version of the
% Document.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 4. MODIFICATIONS\par}
% \end{center}
% 
% You may copy and distribute a Modified Version of the Document under
% the conditions of sections 2 and 3 above, provided that you release
% the Modified Version under precisely this License, with the Modified
% Version filling the role of the Document, thus licensing
% distribution and modification of the Modified Version to whoever
% possesses a copy of it.  In addition, you must do these things in
% the Modified Version:
% 
% \begin{itemize}
% \item[A.]  Use in the Title Page (and on the covers, if any) a title
%   distinct from that of the Document, and from those of previous
%   versions (which should, if there were any, be listed in the
%   History section of the Document).  You may use the same title as a
%   previous version if the original publisher of that version gives
%   permission.
%    
%  \item[B.]  List on the Title Page, as authors, one or more persons
%    or entities responsible for authorship of the modifications in
%    the Modified Version, together with at least five of the
%    principal authors of the Document (all of its principal authors,
%    if it has fewer than five), unless they release you from this
%    requirement.
%    
%  \item[C.]  State on the Title page the name of the publisher of the
%    Modified Version, as the publisher.
%    
%  \item[D.]  Preserve all the copyright notices of the Document.
%    
%  \item[E.]  Add an appropriate copyright notice for your
%    modifications adjacent to the other copyright notices.
%    
%  \item[F.]  Include, immediately after the copyright notices, a
%    license notice giving the public permission to use the Modified
%    Version under the terms of this License, in the form shown in the
%    Addendum below.
%    
%  \item[G.]  Preserve in that license notice the full lists of
%    Invariant Sections and required Cover Texts given in the
%    Document's license notice.
%    
%  \item[H.]  Include an unaltered copy of this License.
%    
%  \item[I.]  Preserve the section Entitled \enquote{History},
%    Preserve its Title, and add to it an item stating at least the
%    title, year, new authors, and publisher of the Modified Version
%    as given on the Title Page.  If there is no section Entitled
%    \enquote{History} in the Document, create one stating the title,
%    year, authors, and publisher of the Document as given on its
%    Title Page, then add an item describing the Modified Version as
%    stated in the previous sentence.
%    
%  \item[J.]  Preserve the network location, if any, given in the
%    Document for public access to a Transparent copy of the Document,
%    and likewise the network locations given in the Document for
%    previous versions it was based on.  These may be placed in the
%    \enquote{History} section.  You may omit a network location for a
%    work that was published at least four years before the Document
%    itself, or if the original publisher of the version it refers to
%    gives permission.
%    
%  \item[K.]  For any section Entitled \enquote{Acknowledgements} or
%    \enquote{Dedications}, Preserve the Title of the section, and
%    preserve in the section all the substance and tone of each of the
%    contributor acknowledgements and/or dedications given therein.
%    
%  \item[L.]  Preserve all the Invariant Sections of the Document,
%    unaltered in their text and in their titles.  Section numbers or
%    the equivalent are not considered part of the section titles.
%    
%  \item[M.]  Delete any section Entitled \enquote{Endorsements}.
%    Such a section may not be included in the Modified Version.
%    
%  \item[N.]  Do not retitle any existing section to be Entitled
%    \enquote{Endorsements} or to conflict in title with any Invariant
%    Section.
%    
%  \item[O.]  Preserve any Warranty Disclaimers.
% \end{itemize}
% 
% If the Modified Version includes new front-matter sections or
% appendices that qualify as Secondary Sections and contain no
% material copied from the Document, you may at your option designate
% some or all of these sections as invariant.  To do this, add their
% titles to the list of Invariant Sections in the Modified Version's
% license notice.  These titles must be distinct from any other
% section titles.
% 
% You may add a section Entitled \enquote{Endorsements}, provided it
% contains nothing but endorsements of your Modified Version by
% various parties---for example, statements of peer review or that the
% text has been approved by an organization as the authoritative
% definition of a standard.
% 
% You may add a passage of up to five words as a Front-Cover Text, and
% a passage of up to 25 words as a Back-Cover Text, to the end of the
% list of Cover Texts in the Modified Version.  Only one passage of
% Front-Cover Text and one of Back-Cover Text may be added by (or
% through arrangements made by) any one entity.  If the Document
% already includes a cover text for the same cover, previously added
% by you or by arrangement made by the same entity you are acting on
% behalf of, you may not add another; but you may replace the old one,
% on explicit permission from the previous publisher that added the
% old one.
% 
% The author(s) and publisher(s) of the Document do not by this
% License give permission to use their names for publicity for or to
% assert or imply endorsement of any Modified Version.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 5. COMBINING DOCUMENTS\par}
% \end{center}
% 
% You may combine the Document with other documents released under
% this License, under the terms defined in section~4 above for
% modified versions, provided that you include in the combination all
% of the Invariant Sections of all of the original documents,
% unmodified, and list them all as Invariant Sections of your combined
% work in its license notice, and that you preserve all their Warranty
% Disclaimers.
% 
% The combined work need only contain one copy of this License, and
% multiple identical Invariant Sections may be replaced with a single
% copy.  If there are multiple Invariant Sections with the same name
% but different contents, make the title of each such section unique
% by adding at the end of it, in parentheses, the name of the original
% author or publisher of that section if known, or else a unique
% number.  Make the same adjustment to the section titles in the list
% of Invariant Sections in the license notice of the combined work.
% 
% In the combination, you must combine any sections Entitled
% \enquote{History} in the various original documents, forming one
% section Entitled \enquote{History}; likewise combine any sections
% Entitled \enquote{Acknowledgements}, and any sections Entitled
% \enquote{Dedications}.  You must delete all sections Entitled
% \enquote{Endorsements}.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 6. COLLECTIONS OF DOCUMENTS\par}
% \end{center}
% 
% You may make a collection consisting of the Document and other
% documents released under this License, and replace the individual
% copies of this License in the various documents with a single copy
% that is included in the collection, provided that you follow the
% rules of this License for verbatim copying of each of the documents
% in all other respects.
% 
% You may extract a single document from such a collection, and
% distribute it individually under this License, provided you insert a
% copy of this License into the extracted document, and follow this
% License in all other respects regarding verbatim copying of that
% document.
% 
% \needspace{3\baselineskip}
% \begin{center}
% {\large\bf 7. AGGREGATION WITH INDEPENDENT WORKS\par}
% \end{center}
% 
% A compilation of the Document or its derivatives with other separate
% and independent documents or works, in or on a volume of a storage
% or distribution medium, is called an \enquote{aggregate} if the
% copyright resulting from the compilation is not used to limit the
% legal rights of the compilation's users beyond what the individual
% works permit.  When the Document is included in an aggregate, this
% License does not apply to the other works in the aggregate which are
% not themselves derivative works of the Document.
% 
% If the Cover Text requirement of section~3 is applicable to these
% copies of the Document, then if the Document is less than one half
% of the entire aggregate, the Document's Cover Texts may be placed on
% covers that bracket the Document within the aggregate, or the
% electronic equivalent of covers if the Document is in electronic
% form.  Otherwise they must appear on printed covers that bracket the
% whole aggregate.
% 
% \needspace{3\baselineskip}
% \begin{center}
%   {\large\bf 8. TRANSLATION\par}
% \end{center}
% 
% Translation is considered a kind of modification, so you may
% distribute translations of the Document under the terms of
% section~4.  Replacing Invariant Sections with translations requires
% special permission from their copyright holders, but you may include
% translations of some or all Invariant Sections in addition to the
% original versions of these Invariant Sections.  You may include a
% translation of this License, and all the license notices in the
% Document, and any Warranty Disclaimers, provided that you also
% include the original English version of this License and the
% original versions of those notices and disclaimers.  In case of a
% disagreement between the translation and the original version of
% this License or a notice or disclaimer, the original version will
% prevail.
% 
% If a section in the Document is Entitled \enquote{Acknowledgements},
% \enquote{Dedications}, or \enquote{History}, the requirement
% (section~4) to Preserve its Title (section~1) will typically require
% changing the actual title.
