% \begin{abstract}
% \edmac, a set of \PlainTeX\ macros, was made at the beginning of 90's 
%  for typesetting critical editions in the traditional
% way, i.e., similar to the Oxford Classical Texts, Teubner, Arden

% \section{Introduction}
%
%    The \edmac{} macros \cite{EDMACTUG} for typesetting critical editions of texts
% have been available for use with TeX since 90's. Since \edmac{}
% was introduced there has been a small but constant demand for a
% version of \edmac{} that could be used with LaTeX. The \Lpack{eledmac}
% package is an attempt to satisfy that request.
%
%
%    \Eledmac{} would not have been possible without the amazing work by
% John Lavagnino\index{Lavagnino, John} 
% and Dominik Wujastyk\index{Wujastyk, Dominik}, 
% the original authors of \edmac.
% I, Peter Wilson, am very grateful for their encouragement and permission to use
% \edmac{} as a base.
% The majority of both the code and this manual are by these two. 
% The tabular material is based on the  
% \tabmac{} code~\cite{TABMAC}, by permission of its author,
% Herbert Breger\index{Breger, Herbert}.
% The verse-related code is by courtesy of Wayne Sullivan, the author
% of \edstanza~\cite{EDSTANZA}, who has kindly supplied more than
% his original macros.
%
% Since 2011's Maïeul Rouquette begun to maintain and extend \eledmac{}. As plain \TeX{} is used by little people, and \LaTeX{} by more people \Eledmac{} and original \edmac{} are more and more distant.
%
%
%
%
% \subsection{Overview}
%
%
% The \Eledmac{} package, together with LaTeX, provides several
% important facilities for formatting critical editions of texts in
% a traditional manner. Major features include:
% \begin{itemize}\addtolength{\itemsep}{-1ex}
% \item automatic stepped line numbering, by page or by section;
% \item sub-lineation within the main series of line numbers;
% \item variant readings automatically keyed to line numbers;
% \item caters for both prose and verse;
% \item multiple series of the footnotes and endnotes;
% \item block or columnar formatting of the footnotes;
% \item simple tabular material may be line numbered;
% \item indexing keyed to page and line numbers.
% \end{itemize}
%
%
% \Eledmac{} allows the scholar engaged in preparing a critical
% edition to focus attention wholly on the task of creating the
% critical text and evaluating the variant readings, text-critical
% notes and testimonia. \LaTeX{} and \Eledmac{} will take care of
% the formatting and visual correlation of all the disparate types
% of information.
%
%
%
%
%
% The original \edmac{} can be used as a `stand alone' processor
% or as part of a process. One example is its use as the formatting
% engine or `back end' for the output of an automatic manuscript
% collation program.  \texttt{COLLATE}, written by 
% Peter\index{Robinson, Peter} Robinson, 
% runs on the Apple Macintosh, can collate simultaneously up to a
% hundred manuscripts of any length, and provides facilities for
% the scholar to tailor the collation interactively. For further
% details of this and other related work, visit the \edmac{} home page
% at \url{http://www.homepages.ucl.ac.uk/~ucgadkw/edmac/index.html}.
%
%    Apart from \Eledmac{} there are some other \LaTeX\ packages for
% critical edition typesetting. As Peter Wilson is not an author, or even a 
% prospective one, of any critical
% edition work he could not provide any opinions on what authors in this
% area might feel comfortable with or how well any of the packages
% meet their needs.
%
%    \texttt{EDNOTES}~\cite{EDNOTES}, by Uwe L\"{u}ck\index{L\"uck, Uwe} and 
% Christian Tapp\index{Tapp, Christian}, is another 
% \LaTeX\ package being developed for critical editions. Unlike \Eledmac{}
% which is based on \edmac, \texttt{EDNOTES} takes a different (internal)
% approach and provides a different set of features. For example it
% provides additional facilities for overlapping lemmas and for
% handling tables. For more information there is a web site at
% \url{http://ednotes.sty.de.vu} or
% email to \url{ednotes.sty@web.de}.
%
%    The \Lpack{poemscol} package~\cite{POEMSCOLTUG} by John Burt\index{Burt, John} 
% is designed for typesetting
% critical editions of collections of poems. I do not know how, or whether,
% \Lpack{poemscol} and \Eledmac{} will work together.
%
% Critical authors may find it useful
% to look at \edmac, \texttt{EDNOTES}, \Eledmac, and \Lpack{poemscol} to 
% see which best meets their needs.
%
%    At the time of writing Peter Wilson knows of two web sites, apart from the \edmac{} 
% home page, that have information on \Eledmac, and other programs.
% \begin{itemize}
% \item Jer\'{o}nimo Leal\index{Leal, Jeronimo@Leal, Jer\'{o}nimo} 
% pointed me to \url{http://www.guit.sssup.it/latex/critical.html}. This
% also mentions another package for critical editions called
% \Lpack{MauroTeX} (\url{http://www.maurolico.unipi.it/mtex/mtex.htm}).
% These sites are both in Italian.
% \item Dirk-Jan Dekker\index{Dekker, Dirk-Jan} maintains
% \url{http://www.djdekker.net/ledmac}
% which is a FAQ for typesetting critical editions and \Eledmac.
% \end{itemize}
%
%
% This manual contains a general description of how to use the \LaTeX\ version of \edmac, namely \Eledmac
% (in sections~\ref{howto} through~\ref{sec:lastuser}); 
% the complete source code for the package,
% with extensive documentation (in sections~\ref{overview} and following)
% ; and an Index to the
% source code. We do not suggest that you need to
% read the source code for this package in order to use it; we
% provide this code primarily for reference, and many of our
% comments on it repeat material that is also found in
% the earlier sections. But no documentation, however
% thorough, can cover every question that comes up, and many can be
% answered quickly by consultation of the code. On a first reading,
% we suggest that you should read only the general documentation in
% sections~\ref{howto}, unless you are particularly interested in the innards of \Eledmac.
%
% \subsection{History}
%
% \subsubsection{EDMAC}
%
% The original version of \edmac{} was \texttt{TEXTED.TEX}, written
% by John Lavagnino\index{Lavagnino, John} 
% in late 1987 and early 1988 for formatting
% critical editions of English plays.
%
% John passed these macros on to Dominik Wujastyk\index{Wujastyk, Dominik}
% who, in
% September--October 1988, added the footnote paragraphing mechanism,
% margin swapping and other changes to suit his own purposes, making the
% style more like that traditionally used for classical texts in Latin and
% Greek (e.g., the Oxford Classical Texts series). He also wrote some
% extra documentation and sent the files out to several people. This
% version of the macros was the first to be called \edmac.
%
% The present version was developed in the summer of 1990, with the
% intent of adding necessary features, streamlining and documenting
% the code, and further generalizing it to make it easily adaptable
% to the needs of editors in different disciplines.  John did most
% of the general reworking and documentation, with the financial
% assistance of the Division of the Humanities and Social Sciences,
% California Institute of Technology.  Dominik adapted the code to
% the conventions of Frank Mittelbach's\index{Mittelbach, Frank}
% \verb"doc" option, and added some documentation, multiple-column
% footnotes, cross-references, and crop marks.\footnote{This version of
% the macros was used to format the Sanskrit text in volume I of {\em
% Metarules of P\=a\d ninian Grammar\/} by Dominik Wujastyk (Groningen:
% Forsten, 1993).} A description by John and Dominik of this version of
% \edmac{} was published as `An overview of \edmac: a \PlainTeX\
% format for critical editions', \emph{TUGboat} \textit{11} (1990),
% pp.\,623--643.
%
% From 1991 through 1994, the macros continued
% to evolve, and were tested at a
% number of sites.  We are very grateful to all the members of the
% (now defunct)
% \verb"edmac@mailbase.ac.uk" discussion group who helped us with
% smoothing out bugs and infelicities in the macros.
% Ron Whitney\index{Whitney, Ron} and our anonymous reviewer at
% the TUG were both of great help in ironing out last-minute
% wrinkles, while Ron made some important suggestions which may help
% to make future versions of \edmac{} even more efficient.
% Wayne
% Sullivan,\index{Sullivan, Wayne} in particular, provided several
% important fixes and contributions, including adapting the
% Mittelbach\slash
% Sch\"opf\index{Sch\"opf, Rainer}\index{Mittelbach, Frank} `New
% Font Selection Scheme' for use with \PlainTeX\ and \edmac.
% Another project Wayne has worked
% on is a \verb"DVI" post-processor which works with an \edmac{}
% that has been slightly modified to output \cs{special}s.  This
% combination enables you to recover to some extent the text of
% each line, as {\sc ascii} code, facilitating the creation of
% concordances, an {\em index verborum}, etc.
%
% At the time of writing (1994), we are pleased to be able to say that \edmac{} is
% being used for real-life book production of several interesting
% editions, such as the Latin texts of Euclid's {\sl
% Elements},\footnote{Gerhard Brey\index{Brey, Gerhard} used \edmac{} in
% the production of Hubert L. L. Busard\index{Busard, Hubert L. L.} and
% Menso Folkerts,\index{Folkerts, Menso} {\em Robert of Chester's
% (?)\index{Chester, Robert of} Redaction of Euclid's\index{Euclid} {\em

%
% \subsubsection{eledmac}
%
%
%
%    Version 1.0 of \tabmac{} was released by 
% Herbert Breger\index{Breger, Herbert} in October
% 1996. This added the capability for typesetting tabular material.
%
%    Version 0.01 of \edstanza{} was released by 
% Wayne Sullivan~\index{Sullivan, Wayne}
% in June 1992, to help a colleague with typesetting Irish verse.
%
%    In March 2003 Peter Wilson started an attempt to port \edmac{}
% from TeX to LaTeX. The starting point was \edmac{} version 3.16 
% as documented on 19 July 1994 (available from CTAN). In August 2003
% the \tabmac{} functions were added; the starting point for these
% being version 1.0 of Ocober 1996. The \edstanza{} (v0.01) functions were
% added in February 2004. Sidenotes and regular footnotes in numbered
% text were added in April 2004. 
%
% This port was called \emph{ledmac}.
% 
% Since July~2011, ledmac is maintained by Ma\"ieul Rouquette. 
%
% Important changes were put in version 1.0, to make eledmac more easily extensible (see \reff{displayoptions}).
% These changes can trigger small problems with the old customization. 
% That is why a new name was selected: \emph{eledmac}. To migrate from ledmac to eledmac, please read Appendix \ref{migration} (p.~\pageref{migration}).
%
% \subsubsection{List of works edited with (e)ledmac}
% A collaborative list of works edited with (e)ledmac is available on \url{https://www.zotero.org/groups/critical_editions_typeset_with_edmac_ledmac_and_eledmac/items}. Please add your own edition made with (e)ledmac.
%
% \section{The \Eledmac{} package}\label{howto}
%
%
%    \Eledmac{} is a three-pass package like
% \LaTeX\ itself. 
% Although your textual apparatus and line
% numbers will be printed even on the first run, it takes two more
% passes through \LaTeX\ to be sure that everything gets to its right
% place. Any changes you make to the input file may similarly
% require three passes to get everything to the right place, if the
% changes alter the number of lines or notes. \Eledmac{} will tell
% you that you need to make more runs, when it notices, but it does
% not expend the labor to check this thoroughly. If you have
% problems with a line or two misnumbered at the top of a page, try
% running \LaTeX\ once or twice more.
%
% A file may mix \emph{numbered} and \emph{unnumbered} text.
% Numbered text is printed with marginal line numbers and can include
% footnotes and endnotes that are referenced to those line numbers:
% this is how you'll want to print the text that you're editing.
% Unnumbered text is not printed with line numbers, and you can't
% use \eledmac's note commands with it: this is appropriate for
% introductions and other material added by the editor around the
% edited text.
%
%
% \section{Options}
% The package can be loaded with a number of global options which are listed here. 
% It is advised to read the relevant parts of the handbook before reading this section.
% \begin{description}
% \item[draft] underlines lemmas in the main text.
% \item[ledsecnolinenumber] is deprecated.
% \item[nocritical] disables tools for critical footnotes (\cs{Afootnote}, \cs{Bfootnote} etc.). If you do not need critical footnotes, this option lets \eledmac\ run faster. 
% It will also preserve room for other packages.
% \item[noeledsec] disables tools for \cs{eledsection} and related commands (\reff{eledsection}).
% \item[noend] disables tools for end footnotes (\cs{Aendnote}, \cs{Bendnote} etc.). If you do not need endnotes, this option lets \eledmac\ run faster. 
% It will also preserve room for other packages.
% \item[nofamiliar] disables tools for familiar footnotes (\cs{footnoteA}, \cs{footnoteB} etc.). If you do not need familiar footnotes, this option lets \eledmac\ run faster.
% It will also preserve room for other packages.
% \item[noledgroup] \eledmac{} allows to use of (two or more) critical series of notes and (two or more) new series of normal notes inside minipage and ledgroup environments (see~\reff{ledgroup}). However, such features use up computer memory, at the expense of other processing needs. So if you do not need this feature, use \verb+noledgroup+ option. This should make \eledmac{} faster.
% \item[nopbinverse] prevents page break inside verses.
% \item[noquotation] by default, the quotation environment is redefined inside numbered text. You can disable this redefinition with \verb|noquotation| (see \reff{noquotation}).
% \item[oldprintnpnumspace] is only to be used if you want to have the (bugged) behavior of \cs{doendnotes} of \Eledmac{} versions prior to v.1.21.0 (see \reff{oldprintnpnumspace})
% \item[parapparatus] by default, the apparatus cannot contain paragraph breaks; this option enables paragraphing inside the apparatus.
% \item[series] \Lpack{eledmac} defines six levels of notes: A, B, C, D, E, Z.
% Using all these levels consumes memory space and processing speed.
% This is why, if your work does not require all of the A-E, Z series, you can narrow down the available number of series.
% For example, if you only need A and B series, call the package with \verb+series={A,B}+ option.
% \item[xindy] and \verb|xindy+hyperref| are for selecting \verb+xindy+ as the index processor (\reff{xindy}).
% \item[widthliketwocolumns] set the width of the text disposed on one column to be the same as the width of the text disposed on two parallel columns with \Lpack{eledpar}. This is useful when alternating between normal and parallel typesetting.
% \end{description}
% \section{Text lines and paragraphs numbering}
% \subsection{Text lines numbering}
% \DescribeMacro{\beginnumbering}
% \DescribeMacro{\endnumbering}
% Each section of numbered text must be preceded by
% \cs{beginnumbering} and followed by \cs{endnumbering}, like: \\
% \cs{beginnumbering} \\
% \meta{text} \\
% \cs{endnumbering}
%
% The \cs{beginnumbering} macro resets the line number to zero,
% reads an auxiliary file called \meta{jobname}.\file{nn} (where
% \meta{jobname} is the name of the main input file for this job,
% and \file{nn} is 1 for the first numbered section, 2 for
% the second section, and so on), and then creates a new version of
% this auxiliary file to collect information during this run. The
% first instance of \cs{beginnumbering} also opens a file called
% \meta{jobname}\file{.end} to receive the text of the endnotes.
% \cs{endnumbering} closes the \meta{jobname}.\file{nn} file.
%
% If the line numbering of a text is to be continuous from start to end,
% then the whole text will be typed between one pair of
% \cs{beginnumbering} and \cs{endnumbering} commands. But your text
% will most often contain chapter or other divisions marking sections
% that should be independently numbered, and these will be appropriate
% places to begin new numbered sections. \Eledmac{} has to read and store
% in memory
% a certain amount of information about the entire section when it
% encounters a \cs{beginnumbering} command, so it speeds up the
% processing and reduces memory use when a text is divided into a larger
% number of sections (at the expense of multiplying the number of
% external files that are generated).
%
% \subsection{Paragraphs}
% \subsubsection{Basis}
% \DescribeMacro{\pstart}
% \DescribeMacro{\pend}
% Within a numbered section, each paragraph of numbered text must
% be marked using the \cs{pstart} and \cs{pend} commands: \\
% \cs{pstart} \\
% \meta{paragraph of text} \\
% \cs{pend}
%
% Text that appears within a numbered section but isn't marked with
% \cs{pstart} and \cs{pend} will not be numbered.
%
% The following example shows the proper section and paragraph
% markup, and the kind of output that would typically be generated:
% \egstart
% \begin{verbatim}
% \beginnumbering
% \pstart
% This is a sample paragraph, with
% lines numbered automatically.
% \pend
%
% \pstart
% This paragraph too has its
% lines automatically numbered.
% \pend
%
% The lines of this paragraph are
% not numbered.
%
% \pstart
% And here the numbering begins
% again.
% \pend
% \endnumbering
% \end{verbatim}
% \egmid
% {\parskip0pt \count255=0
% \everypar{\advance \count255 by 1 \hbox to 1.5em{\the\count255\hfil}}
% This is a sample paragraph\par
% with lines numbered\par
% automatically.\smallskip
%
% This paragraph too\par
% has its lines automatically\par
% numbered.\smallskip
%
% \everypar{\hbox to 1.5em{\hfil}}
% The lines of this paragraph\par
% are not numbered.\smallskip
%
% \everypar{\advance \count255 by 1 \hbox to 1.5em{\the\count255\hfil}}
% And here the numbering\par
% begins again.\par}
% \egend
%
% \subsubsection{Content before specific \cs{pstart} and after \cs{pend}}\label{pstart:optionalarg}
% \changes{v1.12.0}{2014/08/05}{Optional arguments for \cs{pstart} and \cs{pend}.}
% Both \cs{pstart} and \cs{pend} can take a optional argument, in brackets. 
% Its content will be printed before the beginning of \cs{pstart} / after the end of  \cs{pend} instead of the argument of \cs{AtEveryPstart} / \cs{AtEveryPend}.
% If you need to start a \cs{pstart} by brackets, or to add brackets after a \cs{pend}, just add a \cs{relax} between \cs{pstart}/\cs{pend} and the brackets.
%
% For example, \Lpack{eledmac} does not insert \cs{parskip} between paragraphs. This feature allows you to insert it:
% \begin{verbatim}
% \parskip=2\baselineskip% Set the skip between paragraphs
% \AtEveryPend{\vskip\parskip}% Apply after every \Pend
% \end{verbatim}

%. This feature is also useful when typesetting verses (see~\reff{verse}) or \Lpack{eledpar} (see~\reff{eledpar}).
%
% A \cs{noindent} is automatically added before this argument.
% \subsubsection{Content before every \cs{pstart} and after every \cs{pend}}
% \changes{v1.15.0}{2015/01/12}{New commands \cs{AtEveryPstart} and \cs{AtEveryPend}.}
% \label{AtEveryPstart} \DescribeMacro{\AtEveryPstart}\DescribeMacro{\AtEveryPend}
% You can use both \cs{AtEveryPstart} and \cs{AtEveryPend}.
% Their arguments will be printed before every \cs{pstart} begins / after  every \cs{pend} ends.
% \subsubsection{Producting automatically \cs{pstart}\ldots{}\cs{pend}}
% \DescribeMacro{\autopar}
% You can use \cs{autopar} to avoid the nuisance of this paragraph markup
% and still have every paragraph automatically numbered.  The scope of the
% \cs{autopar} command needs to be limited by keeping it within a group, as
% follows:
% \egstart
% \begin{verbatim}
% \begingroup
%   \beginnumbering
%   \autopar
%
%   A paragraph of numbered text.
%
%   Another paragraph of numbered
%   text.
%
%   \endnumbering
% \endgroup
% \end{verbatim}
% \egmid
% {\parskip0pt \count255=0
% \everypar{\advance \count255 by 1 \hbox to 1.5em{\the\count255\hfil}}
% A paragraph of numbered\par
% text.\smallskip
%
% Another paragraph of\par
% numbered text.\par}
% \egend
%
% \cs{autopar} fails, however, on paragraphs that start with a
% \verb"{" or with any other command that starts a new group before it
% generates any text. Such paragraphs need to be started explicitly,
% before the new group is opened,
% using \cs{indent}, \cs{noindent}, or \cs{leavevmode}, or using
% \cs{pstart} itself.\footnote{For a detailed study of the
% reasons for this restriction, see Barbara Beeton, `Initiation
% rites', \textit{TUGboat} \textbf{12} (1991),
% pp.\,257--258.\protect\index{Beeton, Barbara Ann Neuhaus Friend}}
%
% \subsubsection{Numbering paragraphs (\cs{pstart})}
%\changes{v0.12.0}{2011/10/01}{Possibility to number \cs{pstart}.}
% It is possible to insert a number at every \cs{pstart} command. You must use the \DescribeMacro{\numberpstarttrue}\cs{numberpstarttrue} command to have it. You can stop the numbering with \DescribeMacro{\numberpstartfalse}\cs{numberpstartfalse}. 
% You can redefine the command \DescribeMacro{\thepstart}\cs{thepstart} to change style. 
% You can change the value of the pstart number by using \emph{after} \cs{beginnumbering}:
% \begin{verbatim}
% \setcounter{numberpstart}{value}
% \end{verbatim}
% On each \cs{beginnumbering} the numbering restarts.
% \changes{v0.15.0}{2012/06/11}{Possibility to print \cs{pstart} number inside.}
%
% With the \cs{sidepstartnumtrue} command, the number of \cs{pstart} will be printed inside. In this case, the line number will be not printed.
%
% \changes{v1.1.0}{2012/09/25}{Add \cs{labelpstarttrue}.}
% With the \cs{labelpstarttrue} command, a \cs{label} added just after  a \cs{pstart} will refer to the number of this pstart.
% \subsubsection{Languages written in Right to Left}
% If you use languages written in right to left, we \LuaLaTeX\ or \XeLaTeX, so

% \subsubsection{Memory limits}
% \textbf{This paragraph is kept for history, but problem described below should not appear with \Lpack{eledmac}.}
% \DescribeMacro{\pausenumbering}
% \DescribeMacro{\resumenumbering}
% \phantomsection\label{pause}\relax
% \Eledmac{} stores a lot of information about line numbers and
% footnotes in memory as it goes through a numbered section.  But
% at the end of such a section, it empties its memory out, so to
% speak.  If your text has a very long numbered section it is
% possible that your \LaTeX\ may reach its memory limit.  There are
% two solutions to this.  The first is to get a larger \LaTeX\ with
% increased memory.  
% The second solution is to
% split your long section into several smaller ones.  The trouble
% with this is that your line numbering will start again at zero
% with each new section.  To avoid this problem, we provide
% \cs{pausenumbering} and \cs{resumenumbering} which are just
% like \cs{endnumbering} \ldots\ \cs{beginnumbering}, except that
% they arrange for your line numbering to continue across the break.
% Use \cs{pausenumbering} only between numbered paragraphs:
% \egstart
% \begin{verbatim}
% \beginnumbering
% \pstart
% Paragraph of text.
% \pend
% \pausenumbering
%
% \resumenumbering
% \pstart
% Another paragraph.
% \pend
% \endnumbering
% \end{verbatim}
% \egmid
% {\parskip0pt \count255=0
% \everypar{\advance \count255 by 1 \hbox to 1.5em{\the\count255\hfil}}
% Paragraph of\par
% text.\medskip
%
% Another paragraph.\par}
% \egend
%
% We have
% defined these commands as two macros, in case you find it necessary
% to insert text between numbered sections without disturbing the
% line numbering.  But if you are really just using these macros to
% save memory, you might as well say
% \begin{verbatim}
% \newcommand{\memorybreak}{\pausenumbering\resumenumbering}
% \end{verbatim}
% and say \cs{memorybreak} between the relevant \cs{pend} and
% \cs{pstart}.
%
% \subsection{Lineation commands}
% \subsubsection{Disabling lineation}
% \DescribeMacro{\numberlinefalse} \DescribeMacro{\numberlinetrue}
% Line numbering can be disabled with  \cs{numberlinefalse}. It can be enabled again with \cs{numberlinetrue}.
% \subsubsection{Setting lineation start and step}
% \DescribeMacro{\firstlinenum}
% \DescribeMacro{\linenumincrement}
%    By default, \Eledmac{} numbers every 5th line. There are two counters,
% \verb?firstlinenum? and \verb?linenumincrement?, that control this
% behaviour; they can be changed using \cs{firstlinenum}\marg{num} and
% \cs{linenumincrement}\marg{num}. \cs{firstlinenum} specifies the first 
% line that will have a printed number, and \cs{linenumincrement} is 
% the difference between succesive
% numbered lines. For example, to start printing numbers at the first line
% and to have every other line numbered: \\
% \verb?\firstlinenum{1} \linenumincrement{2}?
%
% \DescribeMacro{\firstsublinenum}
% \DescribeMacro{\sublinenumincrement}
% There are similar commands, \cs{firstsublinenum}\marg{num} and 
% \cs{sublinenumincrement}\marg{num} for controlling sub-line numbering.
% \DescribeMacro{\linenumberlist}
% You can define \cs{linenumberlist} to specify a non-uniform distribution
% of printed line numbers. For example: \\
% \verb?\def\linenumberlist{1,2,3,5,7,11,13,17,19,23,29}? \\
% to have numbers printed on prime-numbered lines only. There must be
% no spaces within the definition which consists of comma-separated decimal
% numbers. The numbers can be in any order but it is easier to read if you
% put them in numerical order. Either omitting the definition of
% \cs{linenumberlist} or following the vacuous definition \\
% \verb?\def\linenumberlist{}? \\
% the standard numbering sequence is applied. The standard sequence
% is that specified by the combination of the \texttt{firstlinenum},
% \texttt{linenumincrement}, \texttt{firstsublinenum} and
% \texttt{linenumincrement} counter values.
% \subsubsection{Setting lineation reset}
% \DescribeMacro{\lineation}
% \changes{v1.0.0}{2012/09/15}{Debug in lineation command}
% Lines can be numbered either by page, by pstart or by section; you specify
% this using the \cs{lineation}\marg{arg}
% macro, where \meta{arg} is either
% \texttt{page}, \texttt{pstart} or \texttt{section}. You may only use this command at places
% where numbering is not in effect; you can't change the lineation system
% within a section. You can change it between sections: they don't all
% have to use the same lineation system. 
% The package's standard setting is \verb"\lineation{section}". If the lineation is by pstart, the pstart number will be printed before the line number in the notes.
%
% \subsubsection{Setting line number margin}
% \DescribeMacro{\linenummargin}
% The command \cs{linenummargin}\meta{location} specifies the margin
% where the line (or pstart) numbers will be printed. The permissable value
% for \meta{location} is one out of the list \texttt{left}, \texttt{right},
% \texttt{inner}, or \texttt{outer}, 
% for example \verb"\linenummargin{inner}".
% The package's default setting is \\
% \verb"\linenummargin{left}" \\
% to typeset the numbers in the left hand margin. 
% You can change this whenever you're not in the  middle of 
% making a paragraph. 
%
% More precisely, the value of 
% \cs{linenummargin} used is that in effect at the \cs{pend}
% of a numbered paragraph. Apart from an initial setting for
% \cs{linenummargin}, only change it after a \cs{pend}, whereupon
% it will apply to all following numbered paragraphs, until
% changed again (changing it between a \cs{pstart} and \cs{pend}
% pair will apply the change to all the current paragraph).
%
%
% \subsubsection{Other settings}
%
% \DescribeMacro{\leftlinenum}
% \DescribeMacro{\rightlinenum}
% \DescribeMacro{\linenumsep}
% When a marginal line number is to be printed, there are a
% lot of ways to display it.
% You can redefine \cs{leftlinenum} and \cs{rightlinenum} to
% change the way marginal line numbers are printed in the
% left and right margins respectively; the initial
% versions print the number in font \cs{numlabfont} (described
% below) at a distance \cs{linenumsep} (initially set to one pica)
% from the text.
%
% \subsection{Changing the line numbers}
%
% Normally the line numbering starts at 1 for the first line of
% a section and steps up by one for each line thereafter. There
% are various common modifications of this system, however; the
% commands described here allow you to put such modifications
% into effect.
%
% \DescribeMacro{\startsub}
% \DescribeMacro{\endsub}
% You insert the \cs{startsub} and \cs{endsub} commands in your text
% to turn sub-lineation on and off. In plays, for
% example, stage directions are often numbered with sub-line
% numbers: as line $10.1$, $10.2$,
% $10.3$, rather than as $11$, $12$, and $13$.
% Titles and headings are sometimes numbered with sub-line numbers
% as well.
%
% When sub-lineation is in effect, the line number counter is
% frozen and the sub-line counter advances instead. If one of these
% commands appears in the middle of a line, it doesn't take effect
% until the next line; in other words, a line is counted as a line
% or sub-line depending on what it started out as, even if that
% changes in the middle.
%
% \DescribeMacro{\startlock}
% \DescribeMacro{\endlock}
% The \cs{startlock} command, used in running text, locks the
% line number at its current value, until you say \cs{endlock}.
% It can tell for itself whether you are in a patch of line or
% sub-line numbering. One use for line-number locking is in printing
% poetry: there the line numbers should be those of verse lines
% rather than of printed lines, even when a verse line requires several
% printed lines.
%
% \DescribeMacro{\lockdisp}
% When line-number locking is used,
% several printed lines may have the same line number, and you have to
% specify whether you want the number attached to the first printed
% line or the last, or whether you just want the number printed by
% them all. (This assumes that, on the basis of the settings of
% the previous parameters, it is necessary to display a line number for
% this line.)  You specify your preference using \cs{lockdisp}\marg{arg}; its
% argument is a word, either \texttt{first}, \texttt{last}, or \texttt{all}.
% The package initially sets this as \verb"\lockdisp{first}".
%
% \DescribeMacro{\setline}
% \DescribeMacro{\advanceline}
% In some cases you may want to modify the line numbers that are
% automatically calculated: if you are printing only fragments
% of a work but want to print line numbers appropriate to a complete
% version, for example. The \cs{setline}\marg{num} and 
% \cs{advanceline}\marg{num} commands
% may be used to change the current line's number (or the sub-line
% number, if sub-lineation is currently on). They change both the
% marginal line numbers and the line numbers passed to the notes.
% \cs{setline} takes one argument, the value to which you want
% the line number set; it must be $0$ or greater. \cs{advanceline}
% takes one argument, an amount that should be added to the current
% line number; it may be positive or negative.
%
% \DescribeMacro{\setlinenum}
% The \verb?\setline? and \verb?\advanceline? macros should only be used
% within a \verb?\pstart...\pend? group. The \cs{setlinenum}\marg{num}
% command can be used outside such a group, for example between
% a \verb?pend? and a \verb?\pstart?. It sets the line number 
% to \meta{num}. 
% It has no effect if used within a \verb?\pstart...\pend? group
%
% \DescribeMacro{\linenumberstyle}
% \DescribeMacro{\sublinenumberstyle}
%  Line numbers are nomally printed as arabic numbers. You can
% use \cs{linenumberstyle}\marg{style} to change the numbering style.
% \meta{style} must be one of:
% \begin{itemize}
% \item[\texttt{Alph}] Uppercase letters (A\ldots\ Z).
% \item[\texttt{alph}] Lowercase letters (a\ldots\ z).
% \item[\texttt{arabic}] Arabic numerals (1, 2, \ldots)
% \item[\texttt{Roman}] Uppercase Roman numerals (I, II, \ldots)
% \item[\texttt{roman}] Lowercase Roman numerals (i, ii, \ldots)
% \end{itemize}
% Note that with the \texttt{Alph} or \texttt{alph} styles, `numbers'
% must be between 1 and 26 inclusive.
%
% Similarly \cs{sublinenumberstyle}\marg{style} can be used to change
% the numbering style of sub-line numbers, which is normally arabic numerals.
%
% \DescribeMacro{\skipnumbering}
% When inserted into a numbered line the macro \cs{skipnumbering} causes
% the numbering of that particular line to be skipped; that is, the line 
% number is unchanged and no line number will be printed.
% Note that if you use it in \cs{stanza}, you must call it at the beginning of the verse.
%
% \DescribeMacro{\hidenumbering}
% \changes{v1.21.0}{2015/04/13}{Add \cs{hidenumbering}}
% When inserted into a numbered line the macro \cs{hidenumbering} causes
% the number for that particular line to be hidden; namely, no line number will print.
% Note that if you use it in \cs{stanza}, you must call it at the beginning of the verse.
% \section{The apparatus}
% \subsection{Commands}
% \subsubsection{The lemma}
% \DescribeMacro{\edtext}
% Within numbered paragraphs, all footnotes and endnotes are generated
% by the \cs{edtext} macro:
% \begin{verse}
% \cs{edtext}\marg{lemma}\marg{commands}
% \end{verse}
%
%
% The \meta{lemma} argument is the lemma in the main text: \cs{edtext}
% both prints this as part of the text, and makes it available to the
% \meta{commands} you specify to generate notes. 
%
% For example:
% \egstart
% \begin{verbatim}
% I saw my friend \edtext{Smith}{
% \Afootnote{Jones C, D.}}
% on Tuesday.
% \end{verbatim}
% \egmid
% 1\enspace I saw my friend\\
% 2\enspace Smith on Tuesday.\smallskip
% \hrule width 1.5cm
% \strut {\bf 2} Smith] Jones C, D.
% \egend
%
% The lemma \verb?Smith? is printed as part of this sentence in
% the text, and is also made available to the footnote
% that specifies a variant, \verb?Jones C, D?. The footnote macro
% is supplied with the line number at which the lemma appears
% in the main text.
%
% The \meta{lemma} may contain further \cs{edtext} commands.
%  Nesting makes
% it possible to print an explanatory note on a long passage together with
% notes on variants for individual words within the passage. For
% example:
% \egstart
% \begin{verbatim}
% \edtext{I saw my friend
%   \edtext{Smith}{\Afootnote{Jones
%   C, D.}} on Tuesday.}{
%   \Bfootnote{The date was
%   July 16, 1954.}
% }
% \end{verbatim}
% \egmid
% 1\enspace I saw my friend\\
% 2\enspace Smith on Tuesday.\smallskip
% \hrule width 1.5cm
% \strut {\bf 2} Smith] Jones C, D.\smallskip
% \hrule width 1.5cm
% \strut {\bf 1--2} I saw my friend \\
% Smith on Tuesday.] The\\ date was
% July 16, 1954.
% \egend
%
% However, \cs{edtext} cannot handle overlapping but unnested
% notes---for example, one note covering lines 10--15, and another
% covering 12--18; a \cs{edtext} that starts in the \meta{lemma}
% argument of another \cs{edtext} must end there, too. (The
% \cs{lemma} and \cs{linenum} commands may be used to
% generate overlapping notes if necessary.)
%
% \subsubsection{Footnotes}
%
% The second argument of the \cs{edtext} macro, \meta{commands},

% When all of the six
% are used, the \texttt{A} notes appear in a layer just below the main
% text, followed by the rest in turn, down to the \texttt{Z} notes at
% the bottom.  
% These are the main macros that you will use to construct

%\changes{v1.20.0}{2015/03/22}{Options fulllines in \cs{Xfootnote}.}\label{Xfootnoteopt}
%An optional argument can be added before the text of the footnote. Its value is a comma separated list of options. 
% \label{fulllines}The available options are:
% \begin{itemize}
% \item \verb|fulllines| to disable \cs{twolines} and \cs{morethantwolines} features for this note (cf. \reff{twolines}).
% \item \verb|nonum| to disable line numbering for this note.

% \DescribeMacro{\Aendnote}
% \DescribeMacro{\Bendnote}
% \DescribeMacro{\Cendnote}
% \DescribeMacro{\Dendnote}
% \DescribeMacro{\Eendnote}
% \DescribeMacro{\Zendnote}
% The package also maintains six separate series of endnotes.
%
% If you do not need the endnotes facility, you should use \verb+noend+ option when loading \Lpack{eledmac}.
%
% The mechanism is similar to the one for footnotes: each macro takes one or more optional arguments and one single argument, like:\\
% \cs{Aendnote}\oarg{option}\marg{text}.
% 
% \verb+[<option>]+ can contain a comma separated list of values. Allowed values are: 
% \begin{itemize}
% \item \verb|fulllines| to disable \cs{Xendtwolines} and \cs{Xendmorethantwolines} features for this particular note (cf. \reff{twolines}).
% \item \verb|nosep| to disable the lemma separator for this particular note. 
% \end{itemize}
%
% \label{doendnotes} Normally, endnotes are not printed: you must use the
% \cs{doendnotes}\marg{s}, where \meta{s} is the letter of the series to be printed. Put this command where you want the corresponding set of endnotes printed.
% 
% \changes{v1.22.0}{2015/04/25}{Add \cs{doendnotesbysection} command.}
% \changes{v1.22.0}{2015/04/25}{Standardize endnotes handbook.}
% In this case, all the endnotes of the \meta{s} series are printed, for all numbered section.
% \DescribeMacro{\doendnotesbysection}However, you may want to print the endnotes of one given series covering the first numbered section, then the endnotes of another given series covering the first numbered section, then the endnotes of the first given series covering the second numbered section, then the endnotes of the second given series covering the second numbered section, and so forth.
% In this case, use \cs{doendnotesbysection}\marg{s}.
% For each value of \meta{s}, the first call of the command will print the notes for the first series, the second call will print the notes for the second series etc.
% For example, do:
% \begin{verbatim}
% \section{Endnotes}
% \subsection{First text}
% \doendnotesbysection{A}
% \doendnotesbysection{B}
% \subsection{Second text}
% \doendnotesbysection{A}
% \doendnotesbysection{B}
% \end{verbatim}
% 
% Note that by default inside endnotes no separator is used between the lemma and the content. 
% However you can use the \cs{Xendlemmaseparator} macro to define one (\reff{Xendlemmaseparator}).
%
% As endnotes may be printed at any point in the document they always
% start with the page number where they are called. The
% macro \cs{printnpnum}\marg{num} is used to print these numbers.
% Its default definition is: \\
% \verb?\newcommand*{\printnpnum}[1]{p.#1) }?
%
%
% \subsubsection{Paragraph in critical apparatus}
% By default, no paragraph can be made in the notes of critical apparatus. 
% You can allow it by adding the options \verb+parapparatus+ when loading the package :
% \begin{verbatim}
% \usepackage[parapparatus]{eledmac}
% \end{verbatim}
%
% \DescribeMacro{\lemma}
% \changes{v1.0.0}{2012/09/15}{\cs{lemma} can contain commands.}
% If you want to change the lemma that gets passed to the notes, you
% can do this by using \cs{lemma}\marg{alternative} within the 
% second argument to \cs{edtext}, before the note commands.
% The most common use of this command is to abbreviate the lemma that's
% printed in the notes. For example:
% \egstart
% \begin{verbatim}
% \edtext{I saw my friend
%   \edtext{Smith}{\Afootnote{Jones
%   C, D.}} on Tuesday.}
%   {\lemma{I \dots\ Tuesday.}
%   \Bfootnote{The date was
%   July 16, 1954.}
% }
% \end{verbatim}
% \egmid
% 1\enspace I saw my friend\\
% 2\enspace Smith on Tuesday.\smallskip
% \hrule width 1.5cm
% \strut {\bf 2} Smith] Jones C, D.\smallskip
% \hrule width 1.5cm
% \strut {\bf 1--2} I \dots\ Tuesday.] \\
% The date was July 16, 1954.
% \egend
%
% \DescribeMacro{\linenum}
% \phantomsection\label{linenum}\relax
% You can use \cs{linenum}\marg{arg} to change the line numbers passed to
% the notes. The notes are actually given seven parameters: the page,
% line, and sub-line number for the start of the lemma; the same
% three numbers for the end of the lemma; and the font specifier
% for the lemma. As the argument to \cs{linenum}, you specify
% those seven parameters in that order, separated by vertical bars
% (the \verb"|" character). However, you can retain the value
% computed by \eledmac{} for any number by simply omitting it; and
% you can omit a sequence of vertical bars at the end of the
% argument.  For example, \verb"\linenum{|||23}" changes one number,
% the ending page number of the current lemma.
%
% This command doesn't change the marginal line numbers in any way;
% it just changes the numbers passed to the footnotes. Its use comes in
% situations that \cs{edtext} has trouble dealing with for
% whatever reason. If you need notes for overlapping passages that
% aren't nested, for instance, you can use \cs{lemma} and
% \cs{linenum} to generate such notes despite the limitations of
% \cs{edtext}.  If the \meta{lemma} argument to \cs{edtext} is
% extremely long, you may run out of memory; here again you can
% specify a note with an abbreviated lemma using \cs{lemma} and
% \cs{linenum}. The numbers used in \cs{linenum} need not be
% entered manually; you can use the `\texttt{x-}' symbolic cross-referencing
% commands below (\reff{crossref}) to compute them
% automatically.
%
% Similarly, being able to manually change the lemma's font specifier
% in the notes might be important if you were using multiple scripts or
% languages. The form of the font specifier is three
% separate codes separated by \verb"/" characters, giving the family,
% series, and shape codes as defined within NFSS.
%
% \paragraph{Changing the names of these commands}
%
% The commands for generating the apparatus have been given
% rather bland names, because editors in different fields have
% widely divergent notions of what sort of notes are required, where
% they should be printed, and what they should be called. But this
% doesn't mean you have to type \cs{Afootnote} when you'd rather
% say something you find more meaningful, like \cs{variant}. We
% recommend that you create a series of such aliases and use them
% instead of the names chosen here; all you have to do is put commands
% of this form at the start of your file%
%\footnote{We use \cs{newcommand} and \cs{newcommandx} instead of classical \cs{let} command because the edtabular environments have to modify the notes definition, and we need to use the newest definition of notes. Read the handbook of \Lpack{xargs} to know more about \cs{newcommandx}.}:
% \begin{verbatim}
% \newcommandx{\variant}[2][1,usedefault]{\Afootnote[#1]{#2}}
% \newcommandx{\explanatory}[2][1,usedefault]{\Bfootnote[#1]{#2}}
% \newcommand{\trivial}[1]{\Aendnote{#1}}
% \newcommandx{\testimonia}[2][1,usedefault]{\Cfootnote[#1]{#2}}

% \subsection{Disambiguation of identical words in the apparatus}
% \changes{v1.15.0}{2015/01/12}{New tools to prevent ambiguous references in lemma}
% \changes{v1.23.0}{2015/05/18}{Fix bug with \cs{sameword} when the same lemma is used for multiple notes or for nested \cs{edtext}s.}

% \changes{v1.23.0}{2015/05/18}{Fix bug with \cs{sameword} when the lemma overlaps multiple line.}
% Sometimes, the same word occurs twice (or more) in the same line.
% \Lpack{eledmac} provides  tools to disambiguate references in the critical notes.
% The lemma will be followed by a reference number if a given word occurs more that once in the same line.
% 
% \subsubsection{Basic use}
% \DescribeMacro{\sameword} To use this tool, you have to mark every occurrence of the potentially ambiguous term with the \cs{sameword} command:
%   \begin{verbatim}
%   Lupus \sameword{aut} canis \edtext{\sameword{aut}}{\Afootnote{et}} felix
%   \end{verbatim} 
% In this example, \verb+aut+ will be followed, in the critical note, by the exponent \verb+2+ if it is printed in the same line as the first \verb+aut+, but it won't if it is printed in a different line. The number is printed only after the second run.
%
% \subsubsection{Note about input encoding with UTF-8 processor}
%
% If you use UTF-8 processor, like \XeLaTeX\ or \LuaLaTeX, there should not be any glitches. 
% However, pay attention to how characters are encoded. Similar-looking characters may be represented differently in unicode numbering.
%
% For instance, in Greek, \verb+ᾳ+ has two possible unicode numbers:
% \begin{itemize}
%  \item GREEK SMALL LETTER ALPHA (U+03B1) + COMBINING GREEK YPOGEGRAMMENI (U+0345)
%  \item GREEK SMALL LETTER ALPHA WITH YPOGEGRAMMENI (U+1FB3)
% \end{itemize}
%
% Which unicode number you use depends, many times, on your keyboard configuration (the computer-input system).
%
%  Inside \eledmac, the \cs{sameword} command considers these two unicodes options as different characters. If you use only one unicode number consistently, the distinction will probably make no difference to how your text looks, but \cs{sameword} will process the text inaccurately, based on the unicode numbers. To prevent this, do the following:
% \begin{itemize}
%   \item If you use \XeLaTeX, add this line in your preamble: \verb+ \XeTeXinputnormalization 1+.
%   \item If you use \LuaLaTeX, use the \Lpack{uninormalize} of Michal Hoftich\footnote{\url{https://github.com/michal-h21/uninormalize}.} with the \verb+buffer+ option set to true.
% \end{itemize} 
%
% With these tools, \XeTeX\ / \LuaTeX\ will dynamicaly normalize unicode input when reading the file. 
% Consequently, you will have no problems with the \cs{sameword} command.
% \subsubsection{Use with \cs{lemma} command}
% If you use the \cs{lemma} command, \Lpack{eledmac} cannot know to which occurence of \cs{sameword} in the first argument of \cs{edtext} a word marked with \cs{sameword} in \cs{lemma} should refer.
% 
% For example in the following example:
% \begin{verbatim}
%    some thing
%       \edtext{\sameword{sw}
%               and other \sameword{sw}
%               and again \sameword{sw}
%               it is all}%
%       }{\lemma{\sameword{sw} \ldots all}\Afootnote{critical note}}.%
% \end{verbatim}
% \Lpack{eledmac} cannot know if the ``sw'' in \cs{lemma} refers to the word after ``thing'', after ``other'', or after ``again''.
% 
% Consequently, you have to tell \Lpack{eledmac} which instance of \cs{sameword} in the first argument of \cs{edtext} you want to reference: 
% \begin{itemize}
%   \item In the content of \cs{lemma}, use \cs{sameword} with no optional argument.
%   \item In the first argument of \cs{edtext}, use \cs{sameword} with the optional argument \oarg{X}. \meta{X} is the depth of the \cs{edtext} where the \cs{lemma} is used.
% So if the \cs{lemma} is called in a \cs{edtext} inside another \cs{edtext}, \meta{X} is equal to \verb+2+.
% If the \cs{lemma} is called in a \cs{edtext} ``of first level'', \meta{X} is equal to \verb|1|. If the lemma is called in both 1 and 2 \cs{edtext} depth, \meta{X} is \verb+1,2+. If that word is referenced in the lemma of every \cs{edtext} depth, \meta{X} can also be set to \verb+inlemma+.
% \end{itemize} 
% Note that only words that are actually referenced in a \cs{lemma} need the optional argument. Therefore, the first \cs{sameword} in the example above should have ``1'' as its optional argument, to be referenced correctly in the lemma.
%
% Note also that the \meta{X} does not refer to the level where the \cs{sameword} occurs, but to the level of the \cs{lemma} that refers to that \cs{sameword}. For example: 
% \begin{verbatim}
%    \edtext{some \edtext{\sameword[1]{word}}{\Afootnote{om. M}}
%            and other \sameword{word}
%            and again a \sameword{word}
%            it is all}%
%    }{\lemma{some \sameword{word} \ldots all}\Afootnote{critical note}}.%
% \end{verbatim}
% Here the \cs{sameword} occurs in an \cs{edtext} of level 2, but since it is referenced by \cs{lemma} on level 1, it has ``1'' in the optional argument.

% In the following schema, each framed box represents an \cs{edtext} level. Each number is an occurrence of \cs{sameword}. After a framed box, the text in superscript represents the content of \cs{lemma} for that \cs{edtext} level. The text in subscript at the right of a number represents the content of the optional argument of \cs{sameword}.
% 
%\fbox{%
%  \fbox{%
%	 $1_{inlemma}$ 
%	 \fbox{$2$}
%	 $3_2$%
%       }\textsuperscript{$1$\ldots$3$}%
%     4
%     $5_1$ 
%   }\textsuperscript{1\ldots5}
%
% The \cs{sameword} number~3 is called in a \cs{lemma} related to an \cs{edtext} of level~2.
% It must be marked by ``2''.
%
% The \cs{sameword} number~5 is called in a \cs{lemma} related to \cs{edtext} of level~1. It must be marked by ``1''.
%
% The \cs{sameword} number is called in two \cs{lemma}s: one related to a \cs{edtext} of level~1, the other related to \cs{edtext} of level~2.
% It must be marked by ``1,2''.
% However, as \cs{lemma} is called only in level~1 and~2, ``1,2'' could replaced by ``inlemma''.
%
% The \cs{sameword} number ``2'' is in the first argument of a \cs{edtext} of level~3, but it has no \cs{lemma}-command, so there is no need to mark it.
% 
%
% 
% \subsubsection{Customizing}
% \DescribeMacro{\showwordrank}You can redefine the \cs{showwordrank} macro to change the way the number is printed. The default value is
% \begin{verbatim}
%\newcommand{\showwordrank}[2]{%
%  #1\textsuperscript{#2}%
%}
% \end{verbatim}
%
% \subsection{Alternate footnote formatting}
% If you just launch into \Eledmac{} using the commands outlined
% above, you will get a standard layout for your text and notes.  You
% may be happy to accept this at the very beginning, while you
% get the hang of things, but the standard layout is not particularly
% pretty, and you will certainly want to modify it in due course.
% The package provides ways of changing the fonts and layout of
% your text, but these are not aimed at being totally comprehensive.
% They are enough to deal with simple variations from the norm, and
% to exemplify how you might go on to make more signifiant changes.
%
% \DescribeMacro{\footparagraph}
% \DescribeMacro{\foottwocol}
% \DescribeMacro{\footthreecol}
% By default, all footnotes are formatted as a series of separate
% paragraphs in one column. Three other formats are also
% available for notes, and using these macros you can select a
% different format for a series of notes. 
% \begin{itemize}
% \item \cs{footparagraph} formats
% all the footnotes of a series as a single paragraph;
% \item \cs{foottwocol} formats them as separate paragraphs,
% but in two columns;
% \item \cs{footthreecol}, in three columns. 
% \end{itemize}
% Each of these macros
% takes one argument: a letter (between \verb"A" and \verb"E") for
% the series of notes you want changed.
% So a text with three layers of notes might begin thus:
% \begin{verbatim}
% \footnormal{A}
% \footthreecol{B}
% \footparagraph{C}
% \end{verbatim}
% This would make the A-notes ordinary, B-notes would be in three
% columns, and the bottom layer of notes would be formed into
% a paragraph on each page.

%
% \subsection{Display options}
% \label{displayoptions}
% \changes{v1.0.0}{2012/09/15}{New generic commands to customize footnote display.}
% Since version 1.0, some commands can be used to change the display of the footnotes. All can have an optional argument \oarg{s}, which is the letter of the series --- or a list of letters separated by comma --- depending on which option is applied.
%
% When a length, noted \meta{l}, is used, it can be stretchable: \verb|a plus b minus c|. The final length |m| is calculated by \LaTeX{} to have: $a-c \leq m \leq a+b$. If you use some relative unity\footnote{Like \verb|em| which is the width of a mg.}, it will be relative to fontsize of the footnote, except for commands concerning the place kept by the notes --- including blank space. 
%
% \subsubsection{Control line number printing}
% \DescribeMacro{\numberonlyfirstinline}
% \changes{v1.0.1}{2012/09/16}{Correction on \cs{numberonlyfirstinline} with lineation by pstart or by page.}
% By default, the line number is printed in every note. If you want to print it only the first time for a given line number (i.e one time for line 1, one time for line 2 etc.), you can use \cs{numberonlyfirstinline}\oarg{s}. 
%
% Use \cs{numberonlyfirstinline}\oarg{s}\verb+[false]+ to disable this (\meta{s} can be empty if you want to disable it for every series).
%
% \DescribeMacro{\numberonlyfirstintwolines}
% \changes{v1.1.0}{2012/09/25}{Add \cs{numberonlyfirstintwolines}}
% Suppose you have a lemma on line~2 and a lemma between line~2 and line~3. 
% With \cs{numberonlyfirstinline}, the second lemma is considered to be on the same line as the first lemma.
% But if  you use both \cs{numberonlyfirstinline}\oarg{s} and \cs{numberonlyfirstintwolines}\oarg{s}, the distinction is made.
% Use \cs{numberonlyfirstintwolines}\oarg{s}\verb+[false]+ to disable this (\meta{s} can be empty if you want to disable it for every series).
%
% \changes{v1.20.0}{2015/03/22}{Add \cs{twolines} and \cs{morethantwolines} hooks}
% \label{twolines}
% \DescribeMacro{\twolines}\DescribeMacro{\morethantwolines}
% If a lemma is printed on two subsequent lines, \Eledmac\ will print the first and the last line numbers. 
% Instead of this, it is also possible to print an abbreviation which stands for ``line 1 and subsequent line(s)''.
%
% To achieve this, use \cs{twolines}\oarg{s}\marg{text} and \cs{morethantwolines}\oarg{s}\marg{text}. 
% The \meta{text} argument of \cs{twolines} will be printed if the lemma is on two lines, and the \meta{text} argument of \cs{morethantwolines} will be printed if the lemma is on three or more lines. 
% For example:
% \begin{verbatim}
% \twolines{sq.}
% \morethantwolines{sqq.}
% \end{verbatim}
% Will print ``1sq.'' for a lemma which falls on lines 1-2 and ``1sqq.'' for a lemma which falls on lines 1-4.
%
% \DescribeMacro{\morethantwolines} If you use \cs{twolines} without setting \cs{morethantwolines}, the \meta{text} argument of \cs{twolines} will be used for lemmas which fall on three or more lines.
%
% However, if you want to use a short form (when the lemma overlaps two lines, but not more than two), use \cs{twolinesbutnotmore}\oarg{series}.
%
% It is possible to disable \cs{twolinesbutnotmore}\oarg{series} with \cs{twolinesbutnotmore}\oarg{series}\verb+[false]+.
%
% When you use lineation by page, the final page number, if different from the initial page number,  
% will not be printed, because the final page number is included in the \cs{Xendtwolines} symbol.
% 
% \DescribeMacro{\twolinesonlyinsamepage}
% However, you can force print the final page number with\\ 
% \cs{twolinesonlyinsamepage}\oarg{series}.
% 
% Use \cs{twolinesonlyinsamepage}\oarg{series}\verb+[false]+ to disable this.
%
% You can disable \cs{twolines} and related for a specific note by using the `[fulllines]` argument in the note macro cf.~\reff{fulllines}. 
%
% \label{Xendtwolines}\changes{v1.21.0}{2015/04/13}{Add \cs{Xendtwolines}, \cs{Xendmorethantwolines}, \cs{Xendtwolinesbutnotmore} and \cs{Xendtwolinesonlyinsamepage}.}
% \DescribeMacro{\Xendtwolines}\DescribeMacro{\Xendmorethantwolines}\DescribeMacro{\Xendtwolinesbutnotmore}

% 
%
% \DescribeMacro{\symlinenum}
% For setting a particular symbol in place of the line number, you can use \cs{symlinenum}\oarg{s}\marg{symbol} in combination with \cs{numberonlyfirstinline}\oarg{s}. From the second lemma of the same line, the symbol will be used instead of the line number. Note that any command called in \meta{symbol} must be robust. Use \cs{robustify} to robustify a not robust command.
%
% \DescribeMacro{\nonumberinfootnote}
% You can use \cs{nonumberinfootnote}\oarg{s} if you don't want to have the line number in a footnote. To cancel it, use \cs{nonumberinfootnote}\oarg{s}\verb+[false]+.
%
% \changes{v1.1.0}{2012/09/25}{Add \cs{pstartinfootnote} and \cs{onlypstartinfootnote}}

% \DescribeMacro{\pstartinfootnote}
% You can use \cs{pstartinfootnote}\oarg{s} if you want to print the pstart number in the footnote, before the line and subline number. 
% Use \cs{pstartinfootnote}\oarg{s}\verb+[false]+ to disable this (\meta{s} can be empty if you want to disable it for every series).
% Note that when you change the lineation system, the option is automatically switched :
% \begin{itemize}
%    \item If you use lineation by pstart, the option is enabled.
%    \item If you use lineation by section or by page, the option is disabled.
% \end{itemize}
%
% \DescribeMacro{\pstartinfootnoteeverytime}
% By default, the pstart number is printed only in the part of text where you have called \cs{numberpstarttrue}.
% We don't know why you would like to print the pstart number in the notes and not in the main text. 
% However, if you want to do it, you can call  \cs{pstartinfootnoteeverytime}\oarg{s}. 
% In this case, the pstart number will be printed every time in footnote.
%
% \DescribeMacro{\onlypstartinfootnote}
% In combination with \cs{pstartinfootnote}, you can use \cs{onlypstartinfootnote}\oarg{s} if you want to print only the pstart number in the footnote, and not the line and subline number.
% Use \cs{onlypstartinfootnote}\oarg{s}\verb+[false]+ disable this it (\meta{s} can be empty if you want to disable it for every series).
% 
% \DescribeMacro{\beforenumberinfootnote}
% With \cs{beforenumberinfootnote}\oarg{s}\marg{l}, you can add some space before the line number in a footnote. If the line number is not printed, the space is not either. The default value is 0~pt.
%
% \DescribeMacro{\afternumberinfootnote}
% With \cs{afternumberinfootnote}\oarg{s}\marg{l} you can add some space after the line number in a footnote. If the line number is not printed, the space is not either. The default value is 0.5~em.
%
%\changes{v1.4.3}{2012/12/18}{Add \cs{nonbreakableafternumber}.}
%\DescribeMacro{\nonbreakableafternumber}
% By default, the space defined by \cs{afternumberinfootnote} is breakable. With \cs{nonbreakableafternumber}\oarg{s} it becomes nonbreakable. Use \cs{nonbreakableafternumber}\oarg{s}\verb+[false]+ to disable this (\meta{s} can be empty if you want to disable it for every series).
%
% \DescribeMacro{\beforesymlinenum} 
% With \cs{beforesymlinenum}\oarg{s}\marg{l} you can add some space before the line symbol in a footnote. The default value is value set by \cs{beforenumberinfootnote}.
% 
% \DescribeMacro{\aftersymlinenum} 
% With \cs{aftersymlinenum}\oarg{s}\marg{l} you can add some space after the line symbol in a footnote. The default value is value set by \cs{afternumberinfootnote}.
%
% \DescribeMacro{\inplaceofnumber}
% If no number or symbolic line number is printed, you can add a space, with \cs{inplaceofnumber}\oarg{s}\marg{l}. The default value is 1~em. 
%
% \DescribeMacro{\boxlinenum}
% It could be useful to put the line number inside a fixed box: the content of the note will be printed after this box. 
% You can use \cs{boxlinenum}\oarg{s}\marg{l} to do that.
% To subsequently disable this feature, use \cs{boxlinenum} with length equal to 0~pt.
% One use of this feature is to print line number in a column, and the note in an other column:
% \begin{verbatim}
%\Xhangindent{1em}
%\afternumberinfootnote{0em}
%\boxlinenum{1em}
% \end{verbatim}
%
% \DescribeMacro{\boxsymlinenum}
% \cs{boxsymlinenum}\oarg{s}\marg{l} is the same as \cs{boxlinenum} but for the line number symbol.
% 
% \changes{v1.23.0}{2015/05/18}{Add \cs{boxlinenumalign} and \cs{boxXendlinenumalign}.}
% \DescribeMacro{boxlinenumalign}
% If you put line number in box, it will be aligned left inside the box.
% However, you can change it using  \cs{boxlinenumalign}\oarg{s}\marg{text} where \meta{text} can be the following:
% \begin{description}
%  \item[L] to align left (default value);
%  \item[R] to align right;
%  \item[C] to center.
% \end{description}
% 
% \changes{v1.23.0}{2015/05/18}{Add \cs{boxstartlinenum}, \cs{boxXendstartlinenum}, \cs{boxendlinenum}, \cs{boxXendendlinenum}.}
% When using boxlinenum, \Eledmac{} put all the line number description in the same box. That is, the same box will contain: the start line number, the dash, and either the end line number or the range symbol (like \verb+ff.+).
% However, it is possible to box them in two different boxes.
% \begin{itemize}
%  \item \cs{boxstartlinenum}\oarg{s}\marg{l} will box the start line number in a box of length \meta{l}. The content will be put at the right of the box.
%  \item \cs{boxendlinenum}\oarg{s}\marg{l} will box the dash plus the end line number  or the range symbol in a box  of length \meta{l}. The content will be put at the left of the box.
% \end{itemize}
% 
% With these two commands, it is possible to horizontaly align the dash of line number when using critical notes, to obtain something like:

%
%\subsubsection{Separator between the lemma and the note}
% \paragraph{For footnotes}
% \DescribeMacro{\lemmaseparator}
% By default, in a footnote, the separator between the  lemma and the note is a right bracket (\cs{rbracket}). You can use \cs{lemmaseparator}\oarg{s}\marg{lemmaseparator} to change it. The optional argument can be used to specify the series in which it is used. Note that there is a non-breakable space between the lemma and the separator, but a \textbf{breakable} space between the separator and the lemma.
%
% \DescribeMacro{\beforelemmaseparator}

% For paragraphed footnotes (see below), you can choose the separator between each note by using \cs{parafootsep}\oarg{s}\marg{text}. A common separator is the double pipe (\verb+$||$+), which you can set by using \cs{parafootsep}\verb+{$\parallel$}+. 
% Note that if the symbol defined by \cs{symlinenum} must be used at the beginning of a note, the \cs{parafootsep} is not used before this note.

% Text in paragraphed critical notes is justified, but you can use \cs{Xragged}\oarg{s}+{L}+ if you want it to be ragged left, or \cs{Xragged}\oarg{s}+{R} if you want it to be ragged right.

% \DescribeMacro{\raggedX}
% Text in paragraphed footnotes is justified, but you can use \cs{raggedX}\oarg{s}+{L}+ if you want it to be ragged left, or \cs{raggedX}\oarg{s}+{R} if you want it to be ragged right.

%
% \DescribeMacro{\beforeXnotes}
% You can change the vertical space printed before the rule of the critical notes with \cs{beforeXnotes}\oarg{s}\marg{l}.
% The default value is \verb|1.2em plus .6em minus .6em|.

% \DescribeMacro{\beforenotesX}
%
% You can change the vertical space printed before the rule of the familiar notes with \cs{beforenotesX}\oarg{s}\marg{l}.
% The default value is \verb|1.2em plus .6em minus .6em|.
%
% \textbf{Be careful, the standard \LaTeX\ footnote rule, which is used by \Lpack{eledmac}, decreases 3pt. These 3pt are not changed by this command.}

% \changes{v1.12.0}{2014/08/05}{New hooks: \cs{afterXrule} and \cs{afterruleX}}
% \DescribeMacro{\afterXrule}
% You can change the vertical space printed after the rule of the critical notes with \cs{afterXrule}\oarg{s}\marg{l}.
% The default value is \verb|0pt|.
%
% \textbf{Be careful, the standard \LaTeX\ footnote rule, which is used by \Lpack{eledmac}, adds 2.6pt. These 2.6pt are not changed by this command.}
%
%
% \DescribeMacro{\afterruleX}

%
%
% \DescribeMacro{\preXnotes}
% You can set the space before the first series of critical notes printed on each page
% and set a different amount of space for subsequent the series on the page.
% You can do it with \cs{preXnotes}\marg{l}. Default value is \verb+0pt+.
% You can disable this feature by setting the length to 0pt.
%
% 
%
% \DescribeMacro{\prenotesX}
% You can want the space before the first printed (in a page) series of familiar notes not to be the same as before other series. Default value is \verb+0pt+.
% You can do it with \cs{prenotesX}\marg{l}.
% You can disable this feature by setting the length to 0~pt.
%
% 
% \DescribeMacro{\maxhXnotes}\label{maxhXnotes}
% By default, one series of critical notes can take 80\% of the page size, before being broken to the next page. 
% If you want to change the size use \cs{maxhXnotes}\oarg{s}\marg{l}. 
% Be careful : the length can't be flexible, and is relative to the the current font.
% For example, if you want the note to take, at most, 33% of the text height, do \verb|\maxhXnotes{.33\textheight}|.
%
% \DescribeMacro{\maxhnotesX}
% \cs{maxhnotesX}\oarg{s}\marg{l} is the same as previous, but for familiar footnotes.
%
% Be careful with the two previous commands. 
% Actually, for technical purposes, one paragraphed note is considered as one block. 
% Consequently, it can't be broken between two pages, even if you used these commands. 
% The debug is in the todolist.
%\subsection{Page layout}
%    You should set up the page layout parameters, and in particular the
% \cs{baselineskip} of the footnotes (this is done for you if you
% use the standard \cs{notefontsetup}), before you call any
% of these macros because their action depends on these; 
% too much or too little space will be allotted for the notes on
% the page if these macros use the wrong
% values.\footnote{\phantomsection\label{nobreaks}There
% is one tiny proviso about using paragraphed notes: you shouldn't
% force any explicit line-breaks inside such notes: do not use
% {\tt \bslash par},
% {\tt \bslash break}, or {\tt \bslash penalty=-10000}.  If
% you must have a line-break for some obscure reason, just suggest
% the break very strongly: {\tt \bslash penalty=-9999} will do
% the trick. \reff{nobreak} explains why this restriction
% is necessary.}

% \subsection{Fonts}\label{fonts}
% One of the most important features of the appearance of the notes,
% and indeed of your whole document, will be the fonts used. We will
% first describe the commands that give you control over the
% use of fonts in the different structural elements of the document,
% especially within the notes, and then in
% subsequent sections specify how these commands are used.
%
% For those who are setting up for a large job, here is
% a list of the complete set of \Eledmac{} macros relating to fonts that
% are intended for manipulation by the user: 
% \cs{endashchar}, 
% \cs{fullstop},
% \cs{numlabfont}, and 
% \cs{rbracket}. 
%
%
% \DescribeMacro{\numlabfont}
% Line numbers for the main text
% are usually printed in a smaller font in the margin.
% The \cs{numlabfont} macro is provided as a standard name for
% that font: it is initially defined as \\
% \verb"\newcommand{\numlabfont}{\normalfont\scriptsize}" \\
% You might wish to use a different font if, for example,
% you preferred to have these line numbers printed using
% old-style numerals.
%
%
%
% \DescribeMacro{\endashchar}
% \DescribeMacro{\fullstop}
% \DescribeMacro{\rbracket}
% \font\teni=cmmi10
% A relatively trivial matter relates to punctuation.  In your
% footnotes, there will sometimes be spans of line numbers like
% this: 12--34, or lines with sub-line numbers like this: 55.6. The
% en-dash and the full stop are taken from the same font as the
% numbers, and it all works nicely.  But what if you wanted to use
% old-style numbers, like {\teni12} and {\teni34}?  These look nice
% in an edition, but when you use the fonts provided by \PlainTeX\
% they are taken from a math font which does not
% have the en-dash or full stop in the same places as a text font.
% If you (or your macros) just typed \verb"$\oldstyle 12--34$" or
% \verb"$\oldstyle 55.6$" you would get `{\teni12--34}'and
% `{\teni55.6}'.  So we define \cs{endashchar} and
% \cs{fullstop}, which produce an en-dash and a full stop
% respectively from the normal document font, whatever font you are using
% for the numbers. These two macros are used in the
% macros which format the line numbers in the margins and
% footnotes, instead of explicit punctuation.
%  We also define an \cs{rbracket} macro for the
% right square bracket printed at the end of the lemma in many
% styles of textual notes (including \Eledmac's standard style). 
% For polyglossia, when the lemma is RTL, the bracket automatically switches to a left bracket.
%
%
%
% \DescribeMacro{\select@lemmafont}
% We will briefly discuss \cs{select@lemmafont}
% here because it is important to know about
% it now, although it is not one of the macros you would expect to
% change in the course of a simple job. Hence it is `protected'
% by having the @-sign in its name.
%
% When you use the \cs{edtext} macro to mark a word in your text
% as a lemma, that word will normally be printed again in your
% apparatus.  If the word in the text happens to be in a font such
% as italic or bold you would probably expect it to appear in the
% apparatus in the same font.  This becomes an absolute necessity
% if the font is actually a different script, such as Arabic or
% Cyrillic.  \cs{select@lemmafont} does the work of
% decoding \Eledmac's data about the fonts used to print the lemma in
% the main text and calling up those fonts for printing the lemma in
% the note.
%
% \cs{select@lemmafont} is a macro that takes one long
% argument---the cluster of line numbers passed to the note
% commands. This cluster ends with a code indicating what
% fonts were in use at the start of the lemma.
% \cs{select@lemmafont} selects the appropriate font for the
% note using that font specifier.
%
% \Eledmac{} uses \cs{select@lemmafont} in a standard footnote
% format macro called \cs{normalfootfmt}.  The footnote formats
% for each of the layers \texttt{A} to \texttt{E} are \cs{let} equal
% to \cs{normalfootfmt}.  So all the layers of the footnotes are
% formatted in the same way.
%
%
% \subsection{Changing series}
% \subsubsection{Create a new series}\label{newseries}
%
% If you need more than six series of critical footnotes you can
% create extra series, using \cs{newseries} command. For example to create G and H series \cs{newseries}\verb+G,H+.
% 
% \subsubsection{Delete series}
% As the number of series which are defined increases, \Eledmac{} gets slower.
% If you do not need all of the six standard series (A, B, C, D, E, Z),
% you can load the package with the \verb+series+ option. 
% For example if you need only series~A and~B, use:
% \begin{verbatim}
% \usepackage[series={A,B}]{eledmac}
% \end{verbatim}
% \subsubsection{Series order}
% The default series order is the one called with the \verb+series+ option of the package, or, if this option is not used, A, B, C, D, E, Z. 
% Series order determines footnotes order.
%
% \DescribeMacro{seriesatbegin}\DescribeMacro{seriesatend} However in some specific cases, you need to change the series order at some point inside the document.
% You can use \cs{seriesatbegin}\marg{<s>} to pull up a given series \verb+<s>+ to the beginning, or \cs{seriesatend}\marg{<s>} to push it down to the end.
% \section{Verse}\label{verse}
%
%
%    In 1992 Wayne Sullivan\footnote{Department of Mathematics,
%                        University College,
%                        Dublin 4, Ireland}
%  wrote the \edstanza{} macros~\cite{EDSTANZA}
% for typesetting verse in a critical edition. More specifically
% they were for handling poetry stanzas which use indentation to
% indicate rhyme or metre.
%
%    With Wayne Sullivan's\index{Sullivan, Wayne} permission the majority 
% of this section has 
% been taken from~\cite{EDSTANZA}. Peter has made a few changes to enable his 
% macros to be used in the \LaTeX\ \Lpack{ledmac}, and now in \Lpack{eledmac}.
% package.
% 
%
% \DescribeMacro{\stanza}
% \DescribeMacro{\&}
% Use \verb?\stanza? at the start of a stanza. Each line in a stanza
% is ended by an ampersand (\&), and the stanza itself is ended
% by putting \verb?\&? at the end of the last line.
%
% 
% \DescribeMacro{\stanzaindentbase}
% Lines within a stanza may be indented. The indents are integer multiples
% of the length \verb?\stanzaindentbase?, whose default value is 20pt.
%
% \DescribeMacro{\setstanzaindents}
% In order to use the stanza macros, \textbf{one must set the indentation values}.
% First the value of \verb+\stanzaindentbase+ should be set,
% unless the default value 20pt is desired.
% Every stanza line indentation is a multiple of this.
%
% To specify these
% multiples one invokes, for example \\
% \verb+\setstanzaindents{3,1,2,1,2}+. \\
%
% The numerical entries must be whole numbers, 0 or greater, separated by
% commas without embedded spaces. The first entry
% gives the hanging indentation to be used if the stanza line requires more
% than one print line.
%  
%  If it is known that each stanza line will fit on more than one print line,
% then this first entry should be 0; \TeX\ does less
% work in this case, but no harm ensues if the hanging indentation is not
% 0 but is never used. 
% 
% If you want the hanging verse to be flush right, 
% you can use \cs{hanginsymbol}: see p.~\reff{hfillhanging}.
%
% Enumeration is by stanza lines, not by print lines.
% In the above example the lines are indented one unit, two units, one unit,
% two units, with 3 units of hanging indentation in case a stanza line is too
% long to fit on one print line. 
%
% \subsection{Repeating stanza indents}
%\changes{v0.13.0}{2011/11/08}{New stanzaindentsrepetition counter to repeat stanza indents every \emph{n} verses.}
% \label{stanzaindentsrepetition}Since version 0.13, if the indentation is repeated every \emph{n} verses of the stanza, you can define only the \emph{n} first indentations, and say they are repeated, defining the value of  the \verb+stanzaindentsrepetition+ counter  at \emph{n}. For example:
%\begin{verbatim}
%\setstanzaindents{5,1,0}
%\setcounter{stanzaindentsrepetition}{2}
% \end{verbatim}
%
% is like
%\begin{verbatim}
%\setstanzaindents{0,1,0,1,0,1,0,1,0,1,0}
% \end{verbatim}
%
% \textbf{Be careful: the feature is changed in eledmac 1.5.1. See \reff{change151}.}
%
%If you don't use the  \verb+stanzaindentsrepetition+ counter, make sure you have at least one more numerical
% entry in \verb+\setstanzavalues+ than the number of lines in the stanza.
%
% If you want to disable this feature again, just put the counter to 0: 
% \begin{verbatim}
% \setcounter{stanzaindentsrepetition}{0}
% \end{verbatim}
% The macros make no restriction on the number of lines in a stanza.
% Stanza indentation values (and penalty values) obey \TeX's grouping
% conventions, so if one stanza among several has a different structure,
% its indentations (penalties) may be set within a group; the prior values
% will be restored when the group ends.
%
% \subsection{Manual stanza indent}
% \DescribeMacro{\stanzaindent}
% \DescribeMacro{\stanzaindent*}
% You can set the indent of some specific verse by calling \cs{stanzaindent}\marg{value} at the beginning of the verse, before any other character. In this case, the indent defined by \cs{setstanzaindents} for this verse is skipped, and \marg{value} is used instead.
%
% If you use the mechanism of indent repetition, the next verse will be printed as it should be even if the current verse would have its normal indent value.
% In other words, using \cs{stanzaindent} in a verse does not shift the indent repetition.
%
% However, if you want to shift the indent repetition, so the next verse has the indent normally used for the current verse, use \cs{stanzaindent*} instead of \cs{stanzaindent}.
% \subsection{Stanza breaking}
% \DescribeMacro{\setstanzapenalties}
% When the stanzas run over several pages, it is often
% desirable that page breaks should arise between certain lines in the
% stanza, so a facility for including penalties after stanza lines is
% provided. If you are satisfied with the page breaks, you need not set the
% penalty values. 
%
% The command \\
% \verb+\setstanzapenalties{1,5000,10100,5000,0}+ \\
%  results in a penalty of
% 5000  being placed after the first and third lines of the stanza, and a
% penalty of ${-100}$ after the second. 
%
% The first entry ``1'' is a control
% value. If it is zero, then no penalties are passed on to \TeX,
% which is the default. Values between 0 and 10000 are penalty
% values; values between 10001 and 20000 have 10000 subtracted and the result
% is given as a negative penalty. The mechanism used for indentations and
% penalties requires unsigned values less than 32768. No penalty is placed
% after the last line, so the final \verb+,0+ in then example above could
% be omitted. The control sequence \verb+\endstanzaextra+ can be defined to
% include a penalty. A penalty of 10000 will prevent a page break; such a
% penalty is included automatically where there is stanza hanging indentation.
% A penalty of ${-10000}$ (corresponding to the entry value 20000 in this
% context) forces a page break. Values in between act as suggestions as to the
% desirability of a page break at a given line. There is a subtle interaction
% between penalties and \textit{glue}, so it may take some adjustment of skips
% and penalties to achieve the best results.
% \subsection{Hanging symbol}
% It's possible to insert a symbol in each line of hanging verse, as in French typography for `['.  To insert in eledmac, redefine macro \DescribeMacro{\hangingsymbol}\cmd{\hangingsymbol} with this code:
% \begin{verbatim}
% \renewcommand{\hangingsymbol}{[\,}
% \end{verbatim}
% \label{hfillhanging} You can also use it to force hanging verse to be flush right:
% \begin{verbatim}
% \renewcommand{\hangingsymbol}{\protect\hfill}
% \end{verbatim}
% \subsection{Long verse and page break}
% If you want to prevent page breaks inside long verses, use the option \verb+nopbinverse+ when loading package, or use \cs{lednopbinversetrue}. 
% Read \reff{lednopbinversetrue} for further details.
% \subsection{Various tools}
% \DescribeMacro{\ampersand}
% If you need to print an \& symbol in a stanza, use the \verb?\ampersand? 
% macro, not \verb?\&? which will end the stanza.
%
% \DescribeMacro{\endstanzaextra}
% The macro \verb?\endstanzaextra?, if it is defined, is
% called at the end of a stanza. You could define this, for example,
% to add extra space between stanzas (by default there is no extra 
% space between stanzas); if you are using the \Lpack{memoir} class,
% it provides a length \verb?\stanzaskip? which may come in handy.
%
% \DescribeMacro{\startstanzahook}
%  Similarly, if \verb?\startstanzahook? is defined, it is called by 
% \verb?\stanza? at the 
% start. This can be defined to do something.
%
% \DescribeMacro{\flagstanza}
% Putting \cs{flagstanza}\oarg{len}\marg{text} at the start of a  line
% in a stanza (or elsewhere) will typeset \meta{text} at a 
% distance \meta{len} before
% the line. The default \meta{len} is \verb?\stanzaindentbase?.
%
% For example, to put a verse number before the first line of a stanza
% you could proceed along the lines:
% \begin{verbatim}
% \newcounter{stanzanum}
% \setcounter{stanzanum}{0}
% \newcommand*{\startstanzahook}{\refstepcounter{stanzanum}}
% \newcommand{\numberit}{\flagstanza{\thestanzanum}}
% ...
% \stanza
% \numberit First line...&
%    rest of stanza\&
%
% \stanza
% \numberit First line, second stanza...
% \end{verbatim}
% \subsection{Hanging symbol}
%It's possible to insert a symbol on each line of hanging verse, as in French typography for `['.  To insert in eledmac, redefine macro \DescribeMacro{\hangingsymbol}\cmd{\hangingsymbol} with this code:
%\begin{verbatim}
%\renewcommand{\hangingsymbol}{[\,}
%\end{verbatim}
% \subsection{Text before/after verses}
% It is possible to add text, like a subtitle, before or after verse:
% \begin{itemize}
%   \item \cs{stanza} command can take a optional argument (in brackets). Its content will be printed before the stanza.
%   \item \verb+&+ can be replaced by \cs{newverse} with two optional arguments (in brackets). The first will be printed after the current verse, the second before the next verse.
%   \item \verb+\&+ can take a optional argument (in brackets). Its content will be printed after the stanza.
% \end{itemize}
% \section{Grouping}
%    In a \verb?minipage? environment \LaTeX\ changes \verb?\footnote? numbering from
% arabic to alphabetic and puts the footnotes at the end of the minipage.
%
% \DescribeEnv{minipage}
% You can put numbered text with critical footnotes in a minipage and
% the footnotes are set at the end of the minipage. 
% 
% You can also put familiar footnotes (see section~\ref{sec:desc:familiar})  
% in a minipage but unlike with \verb?\footnote? the numbering scheme is
% unaltered.
%
% \DescribeEnv{ledgroup}\label{ledgroup}
% Minipages, of course, aren't broken across pages. Footnotes in a \verb?ledgroup?
% environment are typeset at the end of the environment, as with minipages,
% but the environment includes normal page breaks. The environment makes no
% change to the textwidth so it appears as normal text; it just might be that
% footnotes appear in the middle of a page, with text above and below.
%
% \DescribeEnv{ledgroupsized}
% The \verb?ledgroupsized? environment is similar to \verb?ledroup? except that
% you must specify a width for the environment, as with a minipage. \\
% \verb?\begin{ledgroupsized}?\oarg{pos}\marg{width}.
%
%    The required \meta{width} argument is the text width for the environment. The
% optional \meta{pos} argument is for positioning numbered text within
% the normal textwidth. It may be one of the characters:
% \begin{itemize}
% \item[l] (left) numbered text is flush left with respect to the normal
%        textwidth. This is the default.
% \item[c] (center) numbered text is in the center of the textwidth.
% \item[r] (right) numbered text is flush right with respect to the
%        normal textwidth.
% \end{itemize}
% Note that normal text, footnotes, and so forth are all flush left.
% 
% \verb?\begin{ledgroupsized}{\textwidth}? is effectively the same as 
% \verb?\begin{ledgroup}?
% 
% 
%
% \section{Crop marks}
%
% The \Lpack{\eledmac} package does not provide crop marks. These are
% available with either the \Lclass{memoir} class~\cite{MEMOIR} or the \Lpack{crop}
% package.
%
%
%
% \section{Cross referencing}
% \changes{v1.12.0}{2014/08/05}{Add hyperlink to crossref (needs \Lpack{hyperref} package).}
% \label{crossref}\relax
% The package provides a simple cross-referencing facility that allows
% you to mark places in the text with labels, and generate page and
% line number references to those places elsewhere 
% using those labels.
%
% \subsection{Basic use}
% 
% \DescribeMacro{\edlabel}
% First you place a label in the text using the command
% \cs{edlabel}\marg{lab}. \meta{lab} can be almost anything you like, including
% letters, numbers, punctuation, or a combination---anything but spaces;
% you might say \verb"\edlabel{toves-3}", for example.\footnote{More precisely,
% you should stick to characters in the \TeX\ categories of `letter'
% and `other'.}
%
% \DescribeMacro{\edpageref}
% \DescribeMacro{\edlineref}
% \DescribeMacro{\sublineref}
% \DescribeMacro{\pstartref}
% Elsewhere in the text, either before or after the \cs{edlabel},
% you can refer to its location via \cs{edpageref}\marg{lab}, or
% \cs{edlineref}\marg{lab}\footnote{Previously, the \cs{edlineref} command was \cs{lineref}. But some packages also define \cs{lineref}. That is why you should use \cs{edlineref} insteaf of \cs{lineref}. \Lpack{eledmac} defines \cs{lineref} as equal to \cs{edlineref}, except if one package has also defined a \cs{lineref} command.}, \cs{sublineref}\marg{lab}, or \cs{pstartref}\marg{lab}. These commands
% will produce, respectively, the page, line, sub-line and pstart on which
% the \cs{edlabel}\marg{lab} command occurred.
%
% 
% An \cs{edlabel} command may appear in the main text, or in the
% first argument of \cs{edtext}, but not in the apparatus itself.  But
% \cs{edpageref}, \cs{edlineref}, \cs{sublineref}, \cs{pstartref} commands can also be used in
% the apparatus to refer to \cs{edlabel}s in the text.
%
% The \cs{edlabel} command works by writing macros to \LaTeX
% \file{.aux} file. You will need to process
% your document through \LaTeX\ twice in order for the references to
% be resolved.
%
% You will be warned if you say \verb"\edlabel{foo}" and \verb"foo"
% has been used as a label before. The \verb"ref" commands will
% return references to the last place in the file marked with this
% label. You will also be warned if a reference is made to an
% undefined label. (This will also happen the first time you
% process a document after adding a new \cs{edlabel} command: the
% auxiliary file will not have been updated yet.)
%
% If you want to refer to a word inside an
% \verb"\edtext{...}{...}" command, the \cs{edlabel} should be defined inside
% the first argument, e.g.,
% \begin{verbatim}
%   The \edtext{creature\edlabel{elephant} was quite
%    unafraid}{\Afootnote{Of the mouse, that is.}}
% \end{verbatim}
%
% If you add the \cs{edlabel} inside some \cs{Xfootnote} command, 
% it will refer to that note, and a suffix \emph{n} will be added to the reference.
% You can redefine this suffix by redefining the command \cs{ledinnotemark}. 
% Its actual definition is:
% \begin{verbatim}

% \DescribeMacro{\xsublineref}
% \DescribeMacro{\xpstartref}
% However, there are situations in which you'll want \Eledmac{} to
% return a number without displaying any
% warning messages about undefined labels or the like: if you want to
% use the reference in a context where \LaTeX{} is looking for a
% number, such a warning will lead to a complaint that the number
% is missing. This is the case for references used within the
% argument to \cs{linenum}, for example. For this situation,
% three variants of the reference commands, with the \verb"x"
% prefix, are supplied: \cs{xpageref}, \cs{xlineref}, \cs{xsublineref} and \cs{xpstartref}.
% They have these limitations:
% \begin{itemize}
%     \item They will not tell you if the label is undefined.
%   \item They must
% be preceded in the file by at least one of the four other
% cross-reference commands---e.g., a \verb"\edlabel{foo}" command,
% even if you never refer to that label---since those commands can all
% do the necessary processing of the \file{.aux} file, and the \cs{x...}
% ones cannot.
%  \item When \Lpack{hyperref} is loaded, the hyperref link won't be added. (Indeed,
%  it's not a limitation, but a feature.)
% \end{itemize}
%
% \DescribeMacro{\xxref}
% The macros \cs{xxref} and 
% \cs{edmakelabel} let you manipulate numbers
% and labels in ways which you may find helpful in tricky
% situations.
%
% The \cs{xxref}\marg{lab1}\marg{lab2} command generates a reference to a sequence of
% lines, for use in the second argument of \cs{edtext}.
% It takes two arguments, both of which are
% labels: e.g., \verb"\xxref{mouse}{elephant}". It calls \cs{linenum}
% (q.v., \reff{linenum} above) and sets the beginning page,
% line, and sub-line numbers to those of the place where
% \verb"\edlabel{mouse}" was placed, and the ending numbers to those where
% \verb"\edlabel{elephant}" occurs.
%
% \DescribeMacro{\edmakelabel}
% Sometimes the \cs{edlabel} command cannot be used to specify exactly
% the page and line desired---for example, if you want to refer to a
% page and line number in another volume of your edition.  In such
% cases, you can use the \cs{edmakelabel}\marg{lab}\marg{numbers} 
% macro so that you can `roll your own' label.  
% For example, if you say `\verb"\edmakelabel{elephant}{10|25|0}"' 
% you will create a new
% label, and a later call to \verb"\edpageref{elephant}" would print
% `10' and \verb"\lineref{elephant}" would print `25'. The sub-line
% number here is zero.  It is usually best to collect your
% \cs{edmakelabel} statements near the top of your document, so that
% you can see them at a glance.

% \DescribeMacro{\ledsidenote}
% \DescribeMacro{\sidenotemargin}
% \cs{ledsidenote}\marg{text} will put \meta{text} into the margin specified
% by the current setting of \cs{sidenotemargin}\marg{location}. The
% permissible value for \meta{location} is one out of the list

% is \\
% \verb?\sidenotemargin{right}? \\
% to typeset \cs{ledsidenote}s in the right hand margin. This is the opposite
% to the default margin for line numbers. The style for a \cs{ledsidenote}
% follows that for a \cs{ledleftnote} or a \cs{ledrightnote} depending
% on the margin it is put in.
%
%    If two, say, \cs{ledleftnote}, commands are called in the same line the

% \section{Familiar footnotes} \label{sec:desc:familiar}
% 
%
%   The \Lpack{footmisc} package~\cite{FOOTMISC} by Robin 
% Fairbairns\index{Fairbairns, Robin} has an option whereby 
% sequential footnote
% marks in the text can be separated by 
% commas\textsuperscript{3,4} like so.
% As a convenience \Eledmac{} provides this automatically.
%
% \DescribeMacro{\multfootsep}
% \cs{multfootsep} is used as the separator between footnote markers.
% Its default definition is: \\
% \verb?\providecommand*{\multfootsep}{\textsuperscript{\normalfont,}}? \\
% and can be changed if necessary.
%
% \DescribeMacro{\footnoteA}
% \DescribeMacro{\footnoteB}
% \DescribeMacro{\footnoteC}
% \DescribeMacro{\footnoteD}
% \DescribeMacro{\footnoteE}
% \DescribeMacro{\footnoteZ}
%    As well as the standard \LaTeX\ footnotes generated via \cs{footnote},
% the package also provides
% six series of additional footnotes called \cs{footnoteA} through
% \cs{footnoteZ}. These have the familiar marker in the text, and 
% the marked text at the foot of the page can be formated using
% any of the styles described for the critical footnotes. Note that
% the `regular' footnotes have the series letter at the end of the macro
% name whereas the critical footnotes have the series letter at the start
% of the name.
%
% \DescribeMacro{\footnormalX}
% \DescribeMacro{\footparagraphX}
% \DescribeMacro{\foottwocolX}
% \DescribeMacro{\footthreecolX}
%  Each of the \verb?\foot...X? macros takes one argument which is the 
% series letter (e.g., \texttt{B}). \cs{footnormalX} is the typical
% footnote format. With \cs{footparagraphX} the series is typeset as one
% paragraph, with \cs{foottwocolX} the notes are set in two columns, and are
% set in three columns with \cs{footthreecolX}.
%
% \DescribeMacro{\thefootnoteA}
% \DescribeMacro{\bodyfootmarkA}
% \DescribeMacro{\footfootmarkA}
% As well as using the \verb?\foot...X? macros to specify the general 
% footnote arrangement for a series, each series uses a set of macros for
% styling the marks. The mark numbering scheme is defined by the
% \cs{thefootnoteA} macro; the default is: \\
% \verb?\renewcommand*{\thefootnoteA}{\arabic{footnoteA}}?\\
% The appearance of the mark in the text is controlled by \cs{bodyfootmarkA}
% which is defined as: \\
% \verb?\newcommand*{\bodyfootmarkA}{%? \\
% \verb?  \hbox{\textsuperscript{\normalfont\@nameuse{@thefnmarkA}}}}? \\
% The command \cs{footfootmarkA} controls the appearance of the mark at the
% start of the footnote text. It is defined as: \\
% \verb?\newcommand*{\footfootmarkA}{\textsuperscript{\@nameuse{@thefnmarkA}}}?
%
%    There are similar command triples for the other series.
%
% Additional footnote series can be easily defined: you just have to use \cs{newseries}, defined above (see \reff{newseries}).
%
% \subsection{Position of the familiar footnotes}
% \DescribeMacro{\fnpos}\DescribeMacro{\mpfnpos}
% There is a historical incoherence in \Lpack{(e)ledmac}. The familiar footnotes are
% before the critical footnotes in a normal page, but after in a minipage or in a ledgroup.
% However, it is possible to change the relative position of both types of footnotes.
% If you want to have familiar footnotes after critical footnotes in a normal page, use:
% \begin{verbatim}
% \fnpos{critical-familiar}
% \end{verbatim}
% Or, if you want a minipage or ledgroup to have critical footnotes after familiar footnotes, use:
% \begin{verbatim}
% \mpfnpos{familiar-critical}
% \end{verbatim}
% \section{Indexing}
%
% \DescribeMacro{\edindex}
% \LaTeX\ provides the |\index|\marg{item} command for specifying that \meta{item}
% and the current page number should be added to the raw index (\file{idx}) file.
% The |\edindex|\marg{item} macro can be used in numbered text to specify
% that \meta{item} and the current page \& linenumber should be added to
% the raw index file.
%
% Note that the file \verb+.idx+ will contain the right reference only after the third run, because of the internal indexing mechanism of \Lpack{eledmac}.
% That means you must first run three times (Xe/Lua)\LaTeX, then run \verb+makeindex+ and finally run again (Xe/Lua)\LaTeX to get an index with the right page numbers.
%
% If the \Lclass{memoir} class or the \Lpack{imakeidx} or \Lpack{indextools} package is used then the macro takes an optional
% argument, which is the name of a raw index file. For example
% |\edindex[line]{item}| will use |line.idx| as the raw file instead of
% |\jobname.idx|.
%
% The minimal version of \Lpack{imakeidx} package to be used is the version 1.3a uploaded on CTAN on 2013/07/11.
%
% Be careful with the order of package loading and index declaration. You must use this order:
% \begin{enumerate}
%     \item Load \Lpack{imakeidx} or \Lpack{indextools} .
%     \item Load \Lpack{eledmac}.
%   \item Declare the index with the macro \cs{makeindex} of \Lpack{imakeidx}/\Lpack{indextools}.
% \end{enumerate}
% \DescribeMacro{\pagelinesep}
% The page \& linenumber combination is written as |page\pagelinesep line|,
% where the default definition is |\newcommand{\pagelinesep}{-}| so that
% an item on page 3, line 5 will be noted as being at |3-5|. You can
% renew |\pagelinesep| to get a different separator.
% 
% |-| is the default
% separator used by the \textsc{MakeIndex} program.
% 
% Consequently, if you want to use an other \cs{pagelinesep}, you have to configure your \verb+.ist+ index style file. For example if you use \verb+:+ as separator\footnote{For further detail, you can read \url{http://tex.stackexchange.com/a/32783/7712}.}.
% \begin{verbatim}
% page_compositor ":"
% delim_r ":
% \end{verbatim}
%
% Read the \textsc{MakeIndex} program's handbook about the \verb+.ist+ file. 
% \DescribeMacro{\edindexlab}
% The |\edindex| process uses a |\label|/|\ref| mechanism to get
% the correct line number. It automatically generates labels
% of the form |\label{\edindexlab N}|, where N is a number, and
% the default definition of |\edindexlab| is: \\
% |\newcommand*{\edindexlab}{$&}| \\
% in the hopes that this will not be used by any other labels
% (|\edindex|'s labels are like |\label{$&27}|).
% You can change |\edindexlab| to something else if you need to.
%
% \subsection{Using xindy}\label{xindy}
% Should you decide to use \verb+xindy+ instead of \verb+makeindex+ 
% to transform your \verb+.idx+ files into \verb+.ind+ files,
% you must use some specific configuration file (\verb+.xdy+) so that
% \verb+xindy+ can understand \Lpack{eledmac} reference syntax of which the scheme is:\\
% \verb+pagenumber-linenumber+
%
% An example of such a file is provided in the ``\href{examples/.}{examples}'' folder.
% Read the xindy handbook to learn how to use it.\footnote{Or, for people 
% who read French, read \url{http://geekographie.maieul.net/174}.}
%
% This file also provides, with an explanation, the settings that are needed to put
% eledmac lines numbers in parenthesis, in order
% to make a better distinction between line numbers and page ranges.
%
% In any case, you must load \Lpack{eledmac} with the \verb+xindy+ option,
% in order to generate a \verb|.xdy| file which is specific to your document.
% This file is needed by the \verb+.xdy+ example file which is in the ``\href{examples/.}{examples}'' folder.
% Its default name is \verb+eledmac-markup-attr.xdy+,
% but you can change it by using your own as an argument of the \verb|xindy+hyperref| option.
%
% If you chose to use both \verb+xindy+ and the \verb+hyperref+ package,
% you must do three more things:
% \begin{enumerate}
%   \item Use \verb|xindy+hyperref| option when loading the \Lpack{eledmac} package.
% When you run (Xe/Lua)\LaTeX with this option, a \verb+.xdy+ configuration file will be generated with all the settings needed to allow internal hyperlinking in each index entry which is created by \cs{edindex}. 
%   \item Use \verb+hyperindex=false+ option when loading hyperref.
%   \item Uncomment --- by removing the semicolons at the beginning of the relevant lines --- some lines in the <code>.xdy</code> file provided in the ``\href{examples/.}{examples}'' folder in order to restore internal links in the index to be used by the standard \verb+index+ command.\footnote{These are the recommended lines to provide the best possible compatibility between hyperref and xindy, even without using \Lpack{eledmac}.}.
% \end{enumerate}
% \section{Tabular material}
%
% \LaTeX's normal |tabular| and |array| environments cannot be used where
% line numbering is being done; more precisely, they can be used but with 
% odd results, so don't use them. However, \eledmac{} provides some simple 
% tabulation environments that can be line numbered. The environments
% can also be used in normal unnumbered text.
%
% \DescribeEnv{edarrayl}
% \DescribeEnv{edarrayc}
% \DescribeEnv{edarrayr}
% \DescribeEnv{edtabularl}
% \DescribeEnv{edtabularc}
% \DescribeEnv{edtabularr}
%    There are six environments; the |edarray*| environments are for math
% and |edtabular*| for text entries. The final |l|, |c|, or |r|
% in the environment names indicate that the entries will be flushleft (|l|),
% centered (|c|) or flushright (|r|). There is no means of specifying
% different formats for each column, nor for specifying a fixed width for
% a column. The environments are centered with respect to the surrounding text.
%
% \egstart
% \begin{verbatim}
% \begin{edtabularc}
% 1 & 2 & 3 \\
% a & bb & ccc \\
% AAA & BB & C
% \end{edtabularc}
% \end{verbatim}
% \egmid
% \centering
% \begin{tabular}{ccc}
% 1 & 2 & 3 \\
% a & bb & ccc \\
% AAA & BB & C
% \end{tabular}\par
% \egend
%
%   Entries in the environments are the same as for the normal
% |array| and |tabular| environments but there must be no ending
% \verb?\\? at the end of the last row. 
% \emph{There must be the same number of column designators (the \&)
% in each row.} There is no equivalent
% to any line drawing commands (such as \cs{hline}).
% However, unlike the normal environments,  the |ed...| environments 
% can cross page breaks.
%
%    Macros like \cs{edtext} can be used as part of an entry.
%
% For example:
% \begin{verbatim}
% \beginnumbering 
% \pstart
% \begin{edtabularl}
% \textbf{\Large I} & wish I was a little bug\edindex{bug} &
% \textbf{\Large I} & eat my peas with honey\edindex{honey} \\
%  & With whiskers \edtext{round}{\Afootnote{around}} my tummy & 
%  & I've done it all my life. \\
%  & I'd climb into a honey\edindex{honey} pot & 
%  & It makes the peas taste funny \\
%  & And get my tummy gummy.\edindex{gummy} & 
%  & But it keeps them on the knife.
% \end{edtabularr}
% \pend
% \endnumbering
% \end{verbatim}
%  produces the following parallel pair of verses.
% 
% \begin{center}
% \setlength{\tabcolsep}{2pt}
% \begin{tabular}{p{4em}rlrl}
% {\footnotesize 1} & \textbf{\Large I} & wish I was a little bug &

%
% \DescribeMacro{\spreadmath}
% \DescribeMacro{\spreadtext}
% |\spreadmath|\marg{math} typesets \marg{math} but the \marg{math} has
% no effect on the calculation of column widths.

%
% \DescribeMacro{\edrowfill}
% The macro |\edrowfill|\marg{start}\marg{end}\marg{fill}
% fills columns number \meta{start} to \meta{end} inclusive with
% \meta{fill}. The \meta{fill} argument can be any horizontal `fill'.
% For example |\hrulefill| or |\upbracefill|.
%
% Note that every row must have the same number of columns, even if 
% some would not appear to be necessary.
%
% The |\edrowfill| macro can be used in both tabular and array environments.
% The typeset appearance of the following code is shown below.
% \begin{verbatim}

% \section{Sectioning commands}
% \changes{v1.1.0}{2012/09/25}{Sectioning commands.}
% \changes{v1.12.0}{2014/08/05}{New sectioning commands.}\label{eledsection}
% \subsection{Sectioning commands without line numbers or critical notes}
% The standard sectioning commands (\cs{chapter}, \cs{section} etc.) can be used inside numbered text.
% In this case, you must call them as an optional argument of \cs{pstart} (\reff{pstart:optionalarg}):
% \begin{verbatim}
% \pstart[\section{section}]
% Pstart content.
% \pend
% \end{verbatim}
% The line which contains them won't be numbered, and you can't add critical notes inside.
% \subsection{Sectioning commands with line numbering and critical notes}
% In the past (between versions 1.1.0 and 1.12.0), 
% these following commands were provided:
% \begin{itemize}
% \item \cs{ledchapter}\oarg{text}\marg{critical text}
% \item \cs{ledchapter*}
% \item \cs{ledsection}\oarg{text}\marg{critical text}
% \item \cs{ledsection*}
% \item \cs{ledsubsection}\oarg{text}\marg{critical text}
% \item \cs{ledsubsection*}
% \item \cs{ledsubsubsection}\oarg{text}\marg{critical text}
% \item \cs{ledsubsubsection*}
% \end{itemize}
% \label{eledsection} These commands are deprecated, and won't be maintened anymore, because of a bad concept.
% Since version 1.12.0, you have to use the following commands:
% \begin{itemize}
% \item \cs{eledchapter}\oarg{text}\marg{critical text}
% \item \cs{eledchapter*}
% \item \cs{eledsection}\oarg{text}\marg{critical text}
% \item \cs{eledsection*}
% \item \cs{eledsubsection}\oarg{text}\marg{critical text}
% \item \cs{eledsubsection*}
% \item \cs{eledsubsubsection}\oarg{text}\marg{critical text}
% \item \cs{eledsubsubsection*}
% \end{itemize}
% Which are equivalent to the \LaTeX\ commands. Each indivual command must be called alone in a \cs{pstart}\ldots\cs{pend}:
% \begin{verbatim}
%\pstart
%\eledsection*{xxxx\ledsidenote{section}}
%\pend
%\pstart
%\eledsubsection*{xxxx\ledsidenote{sub}}
%\pend
%\pstart
%normal text
%\pend
% \end{verbatim}
% At the first run, you will see only the text. It's normal. 
% At the second run, you will see the formating.
% And consequently, at the third run, you will see the table of contents. 
%
% For technical reasons, the page break before \cs{elechapter} can't be added automatically. You have to insert it manually via \cs{beforeeledchapter}, which must be called outside of a numbered section.
% \DescribeMacro{\noeledsec}
% If you aren't going to have any \cs{eledxxx} commands, then load \Eledmac{} with \cs{noeledsec} option. 
% That will suppress the generation of unneeded \file{.eledsec} file, keep memory and make \Lpack{eledmac} faster.
% \section{Quotation environments}
% The \verb+quotation+ and \verb+quote+ environment can be used so that same definition/note appears both inside and outside a numbered section.
% The typographical consequences will resemble the outside numbered sections, based on the styles of the \emph{book} class.
% However, if you use a package that redefines these environments, these redefinitions won't be available inside the numbered section.
% You must open any quotation environments inside a \cs{start}-\cs{pend} block, not outside. 
% A quotation environment MUST not be opened immediately after a \cs{pstart} 
% and MUST not be closed immediately before a \cs{pend}.
%
% \label{noquotation} In some cases, you don't want these environments to be redefined in numbered sections.
% You can load the package with the option \verb+noquotation+ to prevent this redefinition.
% \section{Page breaks}
% \changes{v1.7.0}{2013/11/08}{New features for managing page breaks.}
% \Lpack{Eledmac} and \Lpack{eledpar} break pages automatically.
% However, you may sometimes want to either force page breaks or prevent them. 
% \DescribeMacro{\ledpb} \DescribeMacro{\lednopb} The packages provide two macros: 
% \begin{itemize}
%    \item \cs{ledpb} adds a page break.
%    \item \cs{lednopb} prevents a page break, by adding one line to the current page if needed.
% \end{itemize}
% \textbf{These commands have effect only at the second run}.
% 
% These two commands take effect at the beginning of line in which they are called. For example, if you call \cs{ledpb} at l.~444, the l.~443 will be at the p.~$n$, and the l.~444 at the p.~$n+1$.
% \DescribeMacro{\ledpbsetting} However you can change the behavior, and decide they will have effect after  the end of the line, adding \verb+\ledpbsetting{after}+ at the beginning of your file (better: in your preamble). With the previous example, the l.~444 will be at the p.~$n$ and the l.~445 will be at the p.~$n+1$.
%
% If you are using \Lpack{eledpar} to typeset parallel pages you must use \cs{lednopb} on
% both sides in the two corresponding lines. This is especially important when you are using
% stanzas; otherwise the pages will run out of sync.
% \label{lednopbinversetrue}\DescribeMacro{\lednopbinversetrue} You can also decide to prevent page breaks between two lines of a long verse. To do this, use \verb+nopbinverse+ when loading package, or add \cs{lednopbinversetrue} in the beginning of your file (better: in your preamble). This feature works only with verse of 2 lines, not more. It works at the third run, or at fourth run with \Lpack{eledpar}.
% By default, when a long verse runs normally between two pages, a page break will be placed at the beginning of the verse. However, if you have added\verb+ledpbsetting{after}+, the page break will be placed at the end of the long verse, and the page containing the long verse will have one extra line.
% \section{Miscellaneous}
%
%
% \DescribeMacro{\extensionchars}
% When the package assembles the name of the auxiliary file for a
% section, it prefixes \cs{extensionchars} to the section number.
% This is initially defined to be empty, but you can add some characters to
% help distinguish these files if you like; what you use is likely
% to be system-dependent. If, for example, you said
% \verb"\renewcommand{\extensionchars}{!}", then you would get temporary
% files called \file{jobname.!1}, \file{jobname.!2}, etc.
%
% \DescribeMacro{\ifledfinal}
%    The package can take options. The option `final', which is the default
% is for final typesetting; this sets \verb?\ifledfinal? to TRUE. The other 
% option, `draft', may be useful during earlier stages and sets 
% \verb?\ifledfinal? to FALSE.
%
% \DescribeMacro{\showlemma}
%    The lemma within the text is printed via \verb?\showlemma{lemma}?.
% Normally, or with the `final' option, the definition of \verb?\showlemma? 
% is: \\
% \verb?\newcommand*{\showlemma}[1]{#1}? \\
% so it just produces its argument. 
% With the `draft' option it is defined as \\
% \verb?\newcommand*{\showlemma}[1]{\textit{#1}}? \\
% so that its argument is typeset in an italic font, which may make it 
% easier to check that all lemmas have been treated.
%
%    If you would prefer some other style, you could put something like this
% in the preamble:
% \begin{verbatim}
% \ifledfinal\else
%    \renewcommand{\showlemma}[1]{\textbf{#1}}% or simply ...[1]{#1}
% \fi
% \end{verbatim}
%
%
% \subsection{Known and suspected limitations}
%
% In general, \Eledmac's system for adding marginal line numbers
% breaks anything that makes direct use of the \LaTeX\ insert system,
% which includes marginpars, footnotes and floats.
%
% However, you can use both \cs{footnote} and the familiar footnote
% series notes in numbered text. A \cs{marginpar} in numbered text
% will throw away its contents and send a warning message to the terminal
% and log file, but will do no harm.
%
% \cs{parshape} cannot be used within numbered text, except in a
% very restricted way.
%
% \DescribeMacro{\ballast}
% \phantomsection\label{ballastdesc}\relax
% \LaTeX\ is a three-pass system, but even after a document has
% been processed three times, there are some tricky situations in
% which the page breaks decided by \TeX\ never settle down.  At
% each successive run, \Eledmac{} may oscillate between two
% different sets of page decisions.  To stop this happening, should
% it arise, Wayne Sullivan\index{Sullivan, Wayne} suggested the
% inclusion of the quantity \cs{ballast}.  The amount of \cs{ballast}
% will be subtracted from the penalties which apply to the page
% breaks calculated on the \emph{previous} run through \TeX, thus
% reinforcing these breaks.  So if you find your page breaks
% oscillating, say \\
% \verb"\setcounter{ballast}{100}" \\
% or some such figure, and with any
% luck the page breaks will settle down.  Luckily, this problem
% doesn't crop up at all often.
%
% The restriction on explicit line-breaking in paragraphed footnotes,
% mentioned in a footnote \reff{nobreaks}, and
% described in more detail on \reff{nobreaks-detail}, really is a
% nuisance if that is something you need to do.  There are some possible
% solutions, described by Michael Downes\index{Downes, Michael},
% but this area remains unsatisfactory.
%
%
% \LaTeX\ has a reputation for putting things in the wrong margin after
% a page break. The \Eledmac{} package does nothing to improve the situation
% --- in fact it just makes it more obvious if numbered text crosses a
% page (or column) boundary and the numbers are meant to flip from side
% to side. Try and keep the numbers in the same margin all the time.
% Another aspect of TeX's page breaking mechanism is that when numbering
% lines by the page, the first few numbers after a page break may continue
% as though the lines were still on the previous page.
%
% \DescribeMacro{\pageparbreak}
% If you can't resist flipping the numbers or numbering by the page,
% then you might find that
% judicious use of \cs{pageparbreak} may help if numbering goes awry
% across a page (or column) break. It tries to force TeX into partitioning
% the current paragraph into two invisibly joined paragraphs with a page
% break between them. Insert the command between the last word on one page
% and the first word on the next page. If later you change something earlier
% in the document the natural page break may be in a different place, and you
% will have to adjust the location of \cs{pageparbreak} accordingly.
%
% \DescribeMacro{\footfudgefiddle}
% For paragraphed footnotes \TeX{} has to estimate the amount of space
% required. If it underestimates this then the notes may get too long and
% run off the bottom of the text block. \cs{footfudgefiddle} can be increased
% from its default 64 (say to 68) to increase the estimate. You have to use 
% \cs{renewcommand} for this, like: \\
% \verb?\renewcommand{\footfudgefiddle}{68}?
% 
%
%
% Help, suggestions and corrections will be gratefully received.
%
% \subsection{Use with other packages}
%
%
%    Because of \Eledmac's complexity it may not play well with other
% packages. In particular \Eledmac{} is sensitive to commands in the
% arguments to the \cs{edtext} and \cs{*footnote} macros (this is
% discussed in more detail in section~\ref{text}, and in particular
% the discussion about \cs{no@expands} and \cs{morenoexpands}). You
% will have to see what works or doesn't work in your particular case.
%
%
%    It is possible that \Eledmac{} and the \Lpack{hyperref} package may
% work together. I have not tried this combination but past experience
% with \Lpack{hyperref} suggests that cooperation is unlikely; \Lpack{hyperref}
% changes many \LaTeX\ internals and \Lpack{eledmac} does things that are 
% not normally seen in \LaTeX.
%
% If you want to use the option \emph{bottom} of the \Lpack{footmisc} package, 
% you must load this package \emph{before} the \Eledmac\ package.
% 
% \DescribeMacro{\morenoexpands}
% You can define the macro \cs{morenoexpands} to modify macros that you
% call within \cs{edtext}. Because of the way \Eledmac{} numbers the lines
% the arguments to \cs{edtext} can be processed more than once and in some
% cases a macro should only be processed once. One example is the \cs{colorbox}
% macro from the \Lpack{color} package, which you might use like this:
% \begin{verbatim}
% ... \edtext{\colorbox{mycolor}{lemma}}{\Afootnote{...\colorbox...}}
% \end{verbatim}
% If you actually try 
% this\footnote{Reported by Dirk-Jan Dekker\index{Dekker, Dirk-Jan} 
% in the CTT thread `Incompatibility
% of ``color'' package' on 2003/08/28.}
% you will find \LaTeX\ whinging 
% `\texttt{Missing \{ inserted}', and then things start to fall apart.
% The trick in this case is to specify either:
% \begin{verbatim}
% \newcommand{\morenoexpands}{\let\colorbox=0}
% \end{verbatim}
% or
% \begin{verbatim}
% \makeatletter
% \newcommand{\morenoexpands}{\let\colorbox\@secondoftwo}
% \makeatother
% \end{verbatim}
% (\cs{@secondoftwo} is an internal \LaTeX\ macro that takes two arguments and
% thows away the first one.)
% The first incantation lets color show in both the main text and footnotes
% whereas the second one shows color in the main text but kills it
% in the lemma and footnotes. On the other hand if you use 
% \cs{textcolor} instead, like
% \begin{verbatim}
% ... \edtext{\textcolor{mycolor}{lemma}}{\Afootnote{...\textcolor...}}
% \end{verbatim}
% there is no need to fiddle with \cs{morenoexpands} as the color will
% naturally be displayed in both the text and footnotes. To kill the color
% in the lemma and footnotes, though, you can do:
% \begin{verbatim}
% \makeatletter
% \newcommand{\morenoexpands}{\let\textcolor\@secondoftwo}
% \makeatother
% \end{verbatim}
% It took me a little while to discover all this. If you run into this sort 
% of problem you may have to spend some time experimenting before hitting 
% on a solution.
%
%
% \subsection{Parallel typesetting}\label{eledpar}
%
%
% Peter Wilson has developed the Ledpar package
% as an extension to \Eledmac{} specifically for parallel typesetting
% of critical texts. This also cooperates with the \Lpack{babel} / \Lpack{polyglossia}
% packages for typesetting in multiple languages. The package has been called \emph{eledpar} since September 2012.

% He also developed 
% the \Lpack{ledarab} package for 
% handling parallel Arabic text in critical editions.
% However, this package is not maintened by Maïeul Rouquette. 
% You should use the capabilities of a modern TeX processor, like Xe(La)TeX
%
%

% \section{Implementation overview}\label{overview}
%
%
% We present the \Eledmac{} code in roughly the order in which it's used
% during a run of \TeX. The order is \emph{exactly} that in which
% it's read when you load The \Eledmac{} package, because the same file
% is used to generate this manual and to generate the \LaTeX\ package file.
% Most of what follows consists of macro definitions, but there
% are some commands that are executed immediately---especially
% at the start of the code. The documentation generally describes the
% code from the point of view of what happens when the macros are
% executed, though. As each macro is introduced, its name is printed
% in the margin.
%
% We begin with the commands you use to start and
% stop line numbering in a section of text (Section~\ref{preliminaries}).
% Next comes the machinery for writing and reading the auxiliary file for
% each section that helps us count lines, and for creating list macros
% encoding the information from that file (Section~\ref{lineation}); this
% auxiliary file will be read at the start of each section, to create
% those list macros, and a new version of the file will be started to
% collect information from the body of the section.
%
% Next are commands for marking sections of
% the text for footnotes (Section~\ref{text}), followed by the macros
% that take each paragraph apart, attach the line numbers and insertions,
% and send the result to the vertical list (Section~\ref{paragraph}). The
% footnote commands (Section~\ref{footnotes}) and output routine
% (Section~\ref{output}) finish the main part of the processing;
% cross-referencing (Section~\ref{xref}) and endnotes
% (Section~\ref{endnotes}) complete the story.
%
% In what follows, macros with an @ in their name are more internal
% to the workings of \Eledmac{} than those made up just of
% ordinary letters, just as in \PlainTeX\ (see \thetexbook,
% p.\,344).  You are meant to be able to make free with
% ordinary macros, but the `@' ones should be treated with more
% respect, and changed only if you are pretty sure of what you are
% doing.
%
%
% \section{Preliminaries}
% \label{preliminaries}\relax
%
% We try and use \texttt{l@d} in macro names to help avoid
% name clashes, but this is not a hard and fast rule. For example,
% if an original \edmac{} macro includes \texttt{edmac} We will simply
% change that to \texttt{eledmac}.
%
% Announce the name and version of the package, which is 
% targetted for LaTeX2e.

%<*code>
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{eledmac}[2015/06/02 v1.24.0 LaTeX port of EDMAC]%
%    \end{macrocode}
%
%    Generally, these are the modifications to the original.
% \edmac{} code:
% \begin{itemize}
% \item Replace as many \cs{def}'s by \cs{newcommand}'s as possible
% to avoid overwriting \LaTeX\ macros.
%
% \item Replace user-level \TeX\ counts by \LaTeX\ counters.
%
% \item Use the \LaTeX\ font handling mechanisms.
%
% \item Use \LaTeX\ messaging and file facilities.

%
% Reminder: compare these with the \LaTeX\ list macros in case they

%
% We will make heavy use of lists of information, which will be built
% up and taken apart by the following macros; they are
% adapted from \thetexbook, pp.\,378--379, which discusses
% their use in more detail.
%
% These macros consume a large amount of the run-time of this code.
% We intend to replace them in a future version, and in anticipation
% of doing so have defined their interface in such a way that it is
% not sensitive to details of the underlying code.
%
% \begin{macro}{\list@create}

% \cs{xright@appenditem} creates global control sequences, like \cs{xdef}, and uses two

% control sequence. You say \verb"\gl@p\l\to\z"
% (where \verb"\l" is the list macro, and
% \verb"\z" receives the left item). \verb"\l" is assumed nonempty: say
% \verb"\ifx\l\empty" to test for an empty \verb"\l". The control
% sequences created by \cs{gl@p} are all global.

% generated in one pass, because we don't know the line numbers till we
% ship out the pages. It would be possible if footnotes were never keyed
% to more than one line; but some footnotes gloss passages that may run
% for several lines, and they must be tied to the first line of the
% passage glossed. And even one-line passages require two passes if we
% want line-per-page numbering rather than line-per-section numbering.
%
% So we run \LaTeX\ over the text several times, and each time save
% information about page and line numbers in a `line-list file' to
% be used during the next pass. At the start of each section---whenever
% \cs{beginnumbering} is executed---the line-list file
% for that section
% is read, and the information from it is encoded into a few list
% macros.
%
% We need first to define the different line numbers that are involved
% in these macros, and the associated counters.
%
% \begin{macro}{\line@num}
% The count \cs{line@num} stores the line number that's used in
% marginal line numbering and in notes: counting either from the start of
% the page or from the start of the section, depending on your
% choice for this section. This may be qualified by \cs{subline@num}.
%    \begin{macrocode}
\newcount\line@num
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\subline@num}
% The count \cs{subline@num} stores
% a sub-line number that qualifies \cs{line@num}. For example,
% line $10$ might have sub-line numbers $1$, $2$ and $3$, which might be
% printed as lines $10.1$, $10.2$, $10.3$.
%    \begin{macrocode}
\newcount\subline@num
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\ifsublines@}
% \begin{macro}{\sublines@true}
% \begin{macro}{\sublines@false}
% We maintain an associated flag, \cs{ifsublines@},
% to tell us whether we're within
% a sub-line range or not.
%
% You may wonder why we don't just use the value of \cs{subline@num}
% to determine this---treating anything greater than $0$ as an
% indication that sub-lineation is on. We need a separate flag because
% sub-lineation can be used together with line-number locking in odd
% ways: several pieces of a logical line might be interrupted by
% pieces of sub-lineated text, and those sub-line numbers should not
% return to zero until the next change in the major line number. This
% is common in the typesetting of English Renaissance verse
% drama\index{Middleton, Thomas}, in which stage directions are
% given sub-line numbers: a single line of verse may be
% interrupted by several stage directions.
%    \begin{macrocode}
\newif\ifsublines@
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\absline@num}
% The count \cs{absline@num} stores the
% absolute number of lines since the start
% of the section: that is, the number we've actually printed, no matter
% what numbers we attached to them.
% This value is never printed on an output page, though
% \cs{line@num} will often be equal to it. It is used internally to
% keep track of where notes are to appear and where new
% pages start: using this value rather than \cs{line@num} is a lot
% simpler, because it doesn't depend on the lineation system in use.
%    \begin{macrocode}
\newcount\absline@num
%    \end{macrocode}
% \end{macro}
%
% We'll be calling \cs{absline@num} numbers `absolute' numbers, and
% \cs{line@num} and \cs{subline@num} numbers `visible' numbers.
%
% \begin{macro}{\@lock}
% \begin{macro}{\sub@lock}
% The counts \cs{@lock} and \cs{sub@lock}
% tell us the state of line-number
% and sub-line-number locking. $0$ means we're not within a locked set of
% lines; $1$ means we're at the first line in the set; $2$, at some
% intermediate line; and $3$, at the last line.
%    \begin{macrocode}
\newcount\@lock
\newcount\sub@lock
%    \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\line@list}
% \begin{macro}{\insertlines@list}
% \begin{macro}{\actionlines@list}
% \begin{macro}{\actions@list}
% Now we can define the list macros that will be created from the
% line-list file.  We will maintain the following lists:
% \begin{itemize}\addtolength{\itemsep}{-1ex}
% \item \cs{line@list}: the page and line numbers for every
% lemma marked by \cs{edtext}.
% There are seven pieces of information, separated by vertical bars:
% \phantomsection\label{linenumbers}
% \begin{enumerate}\addtolength{\itemsep}{-1ex}
% \item the starting page,
% \item line, and
% \item sub-line numbers, followed by the
% \item ending page,
% \item line, and
% \item sub-line numbers, and then the
% \item font specifier for the lemma.
% \end{enumerate}
%
%
% These line numbers are all visible numbers.
% The font specifier is a set of four codes for font encoding, 
% family, series, and shape, separated by \verb"/" characters.  
% Thus a lemma that
% started on page $23$, line $35$ and
% went on until page $24$, line $3$
% (with no sub-line numbering), and was typeset in a normal roman font
% would have a line list entry like this: \\
% \verb"23|35|0|24|3|0|OT1/cmr/m/n".
%
% There is one item in this list for every lemma marked by
% \cs{edtext}, even if there are several notes to that lemma, or no
% notes at all. \cs{edtext} reads the data in this list, making it
% available for use in the text of notes.
%
% \item \cs{insertlines@list}: the line numbers of lines that have
% footnotes or other insertions.
% These are the absolute numbers where the corresponding
% lemmas begin. This list contains one entry for every footnote in the
% section; one lemma may contribute no footnotes or many footnotes.
% This list is used by \cs{add@inserts} within \cs{do@line}, to tell
% it where to insert notes.
%
% \item \cs{actionlines@list}: a list of absolute line numbers at
% which we are to perform special
% actions; these actions are specified by the \cs{actions@list} list
% defined below.
%
% \item \cs{actions@list}: action codes corresponding to the line
% numbers in \cs{actionlines@list}. These codes tell \Eledmac{} what action
% it's supposed to take at each of these lines. One action, the
% page-start action, is generated behind the scenes by \Eledmac{} itself;
% the others, for specifying sub-lineation, line-number locking, and
% line-number alteration, are generated only by explicit commands in
% your input file. The page-start and line-number-alteration actions
% require arguments, to specify the new values for the page or line
% numbers; instead of storing those arguments in another list, we have
% chosen the action-code values so that they can encode both the action
% and the argument in these cases. Action codes greater than $-1000$
% are page-start actions, and the code value is the page number; action
% codes less than $-5000$ specify line numbers, and the code value is
% a transformed version of the line number; action codes between these
% two values specify other actions which require no argument.
%
% Here is the full list of action codes and their meanings:
%
% Any number greater than $-1000$ is a page-start action: the line number
% associated with it is the first line on a page, and the action number is
% the page number. (The cutoff of $-1000$ is chosen because negative
% page-number values are used by some macro packages; we assume that
% page-number values less than $-1000$ are not common.)
% Page-start action codes are added to the list by
% the \cs{page@action} macro, which is (indirectly) triggered by the
% workings of the \cs{page@start} macro; that macro should always be
% called in the output routine, just before the page contents are
% assembled. \Eledmac{} calls it in \cs{pagecontents}.
%
% The action code $-1001$ specifies the start of sub-lineation: meaning
% that, starting with the next line, we should be advancing
% \cs{subline@num} at each start-of-line command, rather than
% \cs{line@num}.
%
% The action code $-1002$ specifies the end of sub-lineation. At the
% next start-of-line, we should clear the sub-line counter and start
% advancing the line number. The action codes for starting and ending
% sub-lineation are added to the list by the \cs{sub@action} macro, as
% called to implement the \cs{startsub} and \cs{endsub} macros.
%
% The action code $-1003$ specifies the start of line number locking.
% After the number for the current line is computed, it will remain
% at that value through the next line that has an action code to end
% locking.
%
% The action code $-1004$ specifies the end of line number locking.
%
% The action code $-1005$ specifies the start of sub-line number locking.
% After the number for the current sub-line is computed, it will remain
% at that value through the next sub-line that has an action code to end
% locking.
%
% The action code $-1006$ specifies the end of sub-line number locking.
%
% The four action codes for line and sub-line number locking are added
% to the list by the \cs{do@lockon} and \cs{do@lockoff} macros, as called
% to implement the \cs{startlock} and \cs{endlock} macros.
%
% An action code of $-5000$ or less sets the current visible line
% number (either the line number or the sub-line number, whichever is
% currently being advanced) to a specific positive value. The value of
% the code is $-(5000+n)$, where $n$ is the value (always $\ge 0$)
% assigned to the current line number. Action codes of this type are
% added to the list by the \cs{set@line@action} macro, as called to
% implement the \cs{advanceline} and \cs{setline} macros: this action only
% occurs when the user has specified some change to the line numbers
% using those macros. Normally \Eledmac{} computes the visible line numbers
% from the absolute line numbers with reference to the other
% action codes and the settings they invoke; it doesn't require an
% entry in the action-code list for every line.
%
% Here are the commands to create these lists:
%
%    \begin{macrocode}
\list@create{\line@list}
\list@create{\insertlines@list}
\list@create{\actionlines@list}

% \subsection{Reading the line-list file}
%
%
% \begin{macro}{\read@linelist}
% \cs{read@linelist}\marg{file} is the control sequence
% that's called by \cs{beginnumbering}
% (via \cs{line@list@stuff}) to open and process a
% line-list file; its argument is the name of the file.
% \phantomsection\label{readlinelist}
%    \begin{macrocode}
\newread\@inputcheck
\newcommand*{\read@linelist}[1]{%
  \list@clearing@reg
%    \end{macrocode}
%
% When the file is there we start a new group and make some special
% definitions we'll need to process it: it's a sequence of \TeX\
% commands, but they require a few special settings. We make [ and
% ] become grouping characters: they're used that way in the
% line-list file, because we need to write them out one at a time
% rather than in balanced pairs, and it's easier to just use
% something other than real braces. @ must become a letter, since
% this is run in the ordinary \LaTeX\ context. We ignore carriage
% returns, since if we're in horizontal mode they can get
% interpreted as spaces to be printed.
%
%
% Our line, page, and line-locking counters were already zeroed
% by \cs{line@list@stuff} if this is being called from within
% \cs{beginnumbering}; sub-lineation will be turned off as well
% in that case. On the other hand,
% if this is being called from \cs{resumenumbering}, those things
% should still have the values they had when \cs{pausenumbering}
% was executed.
%
%   If the file is not there, we print an informative message.
%
% Now, after these preliminaries, we start interpreting the file.

%
% This version of \cs{read@linelist} creates list macros
% containing data for the entire section, so they could get rather
% large. It would be no more difficult to read the line-list file
% incrementally rather than all at once: we could read, at the
% start of each paragraph, only the commands relating to that
% paragraph. But this would require that we
% have two line-lists open at once, one for reading, one for
% writing, and on systems without version numbers we'd have to do
% some file renaming outside of \LaTeX\  for that to work. We've
% retained this slower approach to avoid that sort of hacking
% about, but have provided the \cs{pausenumbering} and
% \cs{resumenumbering} macros to help you if you run into
% macro memory limitations (see \reff{pause} above).
%
% \subsection{Commands within the line-list file}
%
% This section defines the commands that can appear within a
% line-list file. They all have very short names because we are
% likely to be writing very large numbers of them out. One macro,
% \cs{@nl}, is especially short, since it will be written to the
% line-list file once for every line of text in a numbered section.
% (Another of these commands, \cs{@lab}, will be introduced in a
% later section, among the cross-referencing commands it is
% associated with.)
%
% When these commands modify the various page and line counters,
% they deliberately do not say \cs{global}. This is because we
% want them to affect only the counter values within the current
% group when nested calls of \cs{@ref} occur. (The code assumes
% throughout that the value of \cs{globaldefs} is zero.)
%
% The macros with \verb"action" in their names contain all the code
% that modifies the action-code list: again, this is so that they
% can be turned off easily for nested calls of \cs{@ref}.
%
% \begin{macro}{\line@list@version}
% The \cs{line@list@version} check if the line-list file does not refers to the older commands of \Lpack{eledmac}. 
% In this case, we stop reading the line-list file.
% Consequently, \cs{line@list@version} should be the first line of a line-number file.
%    \begin{macrocode}
\newcommand{\line@list@version}[1]{%
  \IfStrEq{#1}{\this@line@list@version}%
    {}%
    {\ifledRcol%
       \led@warn@Obsolete{\jobname.\extensionchars\the\section@num}%
     \else%

% \changes{v1.12.0}{2014/08/05}{To ensure compatibility with \cs{musixtex}, \cs{@l} becomes \cs{@l}. Consequently, \cs{@l@reg} becomes \cs{@nl@reg}.}
% \cs{@nl} does everything related to the start of a
% new line of numbered text.
%
% In order to get the \verb?\setlinenum? to work Peter Wilson had to slip in some new
% code at the start of the macro, to get the timing of the actions
% correct. The problem was that his original naive implementation
% of \verb?\setlinenum? had a unfortunate tendency to change the
% number of the last line of the \emph{preceding} paragraph. 
% The new code is sort of based on the page number handling and
% \verb?\setline? It seems
% that a lot of fiddling with the line number internals is required.
%
% In November 2004 in order to accurately determine page numbers Peter Wilson added 
% these to the macro. It is now: \\
% \cs{@nl}\marg{page counter number}\marg{printed page number} \\
% I don't (yet) use the printed number (i.e., the \verb?\thepage?) but
% it may come in handy later. The macro \cs{fix@page} checks if a new
% page has started.

% \subsection{Writing to the line-list file}
%
% We've now defined all the counters, lists, and commands involved in
% reading the line-list file at the start of a section. Now we'll
% cover the commands that \Eledmac{} uses within the text of a
% section to write commands out to the line-list.
%
% \begin{macro}{\linenum@out}
% The file will be opened on output stream \cs{linenum@out}.

% \end{macro}
%
% \begin{macro}{\iffirst@linenum@out@}
% \begin{macro}{\first@linenum@out@true}
% \begin{macro}{\first@linenum@out@false}
% Once any file is opened on this stream, we keep it open forever, or
% else switch to another file that we keep open. The reason is that
% we want the output routine to write the page number for every page
% to this file; otherwise we'd have to write it at the start of
% every line.
% But it's not very easy for the output routine to tell whether an
% output stream is open or not. There's no way to test the status of
% a particular output stream directly, and
% the asynchronous nature of output routines makes the
% status hard to determine by other means.
%
% We can manage pretty well by means of the \cs{iffirst@linenum@out@}
% flag; its inelegant name suggests the nature of the problem that
% made its creation necessary. It's set
% to be \verb"true" before any \cs{linenum@out} file is opened. When such a file
% is opened for the first time, it's done using \cs{immediate}, so that
% it will at once be safe for the output routine to write to it; we then
% set this flag to \verb"false".

% \begin{macro}{\page@start}
% Originally the commentary was: \cs{page@start} writes a command to the line-list
% file noting the current page number;
% when used within an output routine, this should be called so as to place
% its \cs{write} within the box that gets shipped out, and as close to
% the top of that box as possible.
%
% However, in October 2004 Alexej Krukov\index{Krukov, Alexej} discovered that
% when processing long paragraphs that included Russian, Greek and Latin texts
% \Eledmac{} would go into an infinite loop, emitting thousands of blank pages.

% \section{Marking text for notes}
% \label{text}\relax
%
% The \cs{edtext} (or \cs{critext}) macro is used to create all 
% footnotes and endnotes,
% as well as to print the portion of the main text to which a given note
% or notes is keyed. The idea is to have that lemma appear only once in
% the \file{.tex} file: all instances of it in the main text and in the
% notes are copied from that one appearance.
%
% For convenience, I will use \cs{*text} when I do not need to distinguish
% between \cs{edtext} and \cs{critext}.
% The \cs{*text} macros take two arguments, the only difference between
% \cs{edtext} and \cs{critext} is how the second argument is delineated.
%
% \cs{critext} requires two arguments. At any point within numbered
% text, you use it by saying:
% \begin{verbatim}
%    \critext{#1}#2/
% \end{verbatim}
% Similarly \cs{edtext} requires the same two arguments
% but you use it by saying:
% \begin{verbatim}
%    \edtext{#1}{#2}
% \end{verbatim}
%
% \begin{itemize}\addtolength{\itemsep}{-1ex}
% \item \verb"#1" is the piece of the main text being glossed;
% it gets added to the
% main text, and is also used as a lemma for notes to it.
%
% \item \verb"#2" is a series of subsidiary macros that generate
% various kinds of notes. With \cs{critext} the \verb"/" after \verb"#2" \emph{must} appear:
% it marks the end of the macro. (\thetexbook,
% p.\,204, points out that when
% additional text to be matched follows the arguments like this, spaces
% following the macro are not skipped, which is very desirable since
% this macro will never be used except within text. Having an
% explicit terminator also helps keep things straight when nested
% calls to \cs{critext} are used.)  Braces around
% \verb"#2" are optional with \cs{critext} and required for \cs{edtext}.
% \end{itemize}
%
% The \cs{*text} macro may be used (somewhat) recursively; that
% is, \cs{*text} may be used within its own first argument. The
% code would be much simpler without this feature, but nested notes
% will commonly be necessary: it's quite likely that we'll have an
% explanatory note for a long passage and notes on variants for
% individual words within that passage. The situation we can't
% handle is overlapping notes that aren't nested: for example, one
% note covering lines 10--15, and another covering 12--18. You can
% handle such cases by using the \cs{lemma} and \cs{linenum}
% macros within \verb"#2": they alter the copy of the lemma and the
% line numbers that are passed to the notes, and hence allow you to
% overcome any limitations of this system, albeit with extra
% effort.
%
% The recursive operation of \cs{*text} will fail if you try to use a copy
% that is called something other than \cs{*text}. In order to handle
% recursion, \cs{*text} needs to redefine its own definition temporarily
% at one point, and that doesn't work if the macro you are calling is
% not actually named \cs{*text}. There's no problem as long as \cs{*text}
% is not invoked in the first argument. If you want to call \cs{*text}
% something else, it is best to create instead a macro that expands
% to an invocation of \cs{*text}, rather than copying \cs{*text} and giving
% it a new name; otherwise you will need to add an appropriate
% definition for your new macro to \cs{morenoexpands}.
%
% Side effects of our line-numbering code make it impossible to use
% the usual footnote macros directly within a paragraph whose lines are
% numbered (see comments to
% \cs{do@line}, \reff{doline}).
% Instead, the appropriate note-generating command
% is appended to the list macro \cs{inserts@list}, and when \cs{pend}
% completes the paragraph it inserts all the notes at the proper places.
%
% Note that we don't provide previous-note information, although it's
% often wanted; your own macros must handle that. We can't do it
% correctly without keeping track of what kind of notes have gone past:
% it's not just a matter of remembering the line numbers associated with
% the previous invocation of \cs{*text}, because that might have been for
% a different kind of note. It is preferable for your footnote macros
% to store and recall this kind of information if they need it.
%
%
% \subsection{{\tt \protect\bslash edtext} (and {\tt \protect\bslash critext})
%  itself}
%
% The various note-generating macros might want to request that
% commands be executed not at once, but in close connection with the
% start or end of the lemma. For example, footnote numbers in the text
% should be connected to the end of the lemma; or, instead of a single
% macro to create a note listing variants, you might want to use
% several macros in series to create individual variants, which would
% each add information to a private macro or token register, which in
% turn would be formatted and output when all of \verb"#2" for the lemma
% has been read.
%
% \begin{macro}{\end@lemmas}
% To accomodate this, we provide a list macro
% to which macros may add commands that should subsequently
% be executed at the end of the lemma when that lemma is added
% to the text of the paragraph. A macro should add its contribution to
% \cs{end@lemmas} by using \cs{xleft@appenditem}.
% (Anything that needs to be done at
% the \emph{start} of the lemma may be handled using \cs{aftergroup}, since
% the commands specified within \cs{edtext}'s second argument are
% executed within a group that ends just before the lemma is added to
% the main text.)
%
% \cs{end@lemmas} is intended for the few things that need to be
% associated with the end of the lemma, like footnote numbers. Such
% numbers are not implemented in the current version, and indeed
% no use is currently made of \cs{end@lemmas} or of the \cs{aftergroup}
% trick. The general
% approach would be to define a macro to be used within the second
% argument of \cs{edtext} that would add the appropriate command to
% \cs{end@lemmas}.
%
% Commands that are added to this list should always take care
% not to do anything that adds possible line-breaks to the output;
% otherwise line numbering could be thrown off.
%    \begin{macrocode}
\list@create{\end@lemmas}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\dummy@text}
% We now need to define a number of macros that allow us to weed out
% nested instances of \cs{edtext}, and other problematic macros, from
% our lemma. This is similar to what we did in reading the line-list
% file using \cs{dummy@ref} and various redefinitions---and that's
% because nested \cs{edtext}s macros create nested \cs{@ref} entries
% in the line-list file.
%
% Here's a macro that takes the same arguments as
% \cs{critext} but merely returns the first argument and ignores
% the second.
%    \begin{macrocode}
\long\def\dummy@text#1#2/{#1}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\dummy@edtext}
% \LaTeX\ users are not used to delimited arguments, so we provide
% a \cs{edtext} macro as well.
%    \begin{macrocode}
\newcommand{\dummy@edtext}[2]{#1}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\dummy@edtext@showlemma}
% Some time, we want to obtain only the first argument of \cs{edtext}, while also wrapping it in \cs{showlemma}. For example, when printing a \cs{eledsection}.
%    \begin{macrocode}
\newcommand{\dummy@edtext@showlemma}[2]{\showlemma{#1}}%
%    \end{macrocode}
% \end{macro}
%
% We're going to need another macro that takes one argument and ignores
% it entirely. This is supplied by the \LaTeX\ \cs{@gobble}\marg{arg}.
%
% \begin{macro}{\no@expands}
% \begin{macro}{\morenoexpands}
% We need to turn off macro expansion for certain sorts of macros we're
% likely to see within the lemma and within the notes.
%
% The first class is font-changing macros. We suppress expansion for
% them by letting them become equal to zero.\footnote{Since `control
% sequences equivalent to characters are not expandable'---\thetexbook,
% answer to Exercise 20.14.} This is done because we want to
% pass into our notes the generic commands to change to roman or
% whatever, and not their expansions that will ask for a particular style at
% a specified size.  The notes may well be in a smaller font, so the
% command should be expanded later, when the note's environment is in
% effect.
%
% A second sort to turn off includes a few of the accent macros.
% Most are not a problem: an accent that's expanded to an \cs{accent}
% command may be harder to read but it works just the same. The
% ones that cause problems are: those that use alignments---\TeX\
% seems to get confused about the difference between alignment
% parameters and macro parameters; those that use temporary control
% sequences; and those that look carefully at what the current font
% is.
%
% (The \cs{copyright} macro defined in \PlainTeX\ has this sort of
% problem as well, but isn't used enough to bother with. That macro,
% and any other that causes trouble, will get by all right if you put
% a \cs{protect} in front of it in your file.)
%
% We also need to eliminate all \Eledmac{} macros like \cs{edlabel} and
% \cs{setline} that write things to auxiliary files: that writing
% should be done only once. And we make
% \cs{edtext} itself, if it appears within its own
% argument, do nothing but copy its first argument.
%
% Finally, we execute \cs{morenoexpands}. The version of
% \cs{morenoexpands} defined here does nothing; but you may define
% a version of your own when you need to add more expansion
% suppressions as needed with your macros. That makes it possible
% to make such additions without needing to copy or modify the
% standard \Eledmac{} code. If you define your own
% \cs{morenoexpands}, you must be very careful about spaces: if the
% macro adds any spaces to the text when it runs, extra space
% will appear in the main text when \cs{edtext} is used.
%
% (A related problem, not addressed by these two macros,
% is that of characters whose category code is changed by any
% the macros used in the arguments to \cs{edtext}. Since the
% category codes are set when the arguments are scanned, macros
% that depend on changing them will not work. We have most often
% encountered this with characters that are made `active' within
% text in some, but not all, of the languages used within the document.
% One way around the problem, if it takes this form,
% is to ensure that those characters are \emph{always} active; within
% languages that make no special use of them, their associated
% control sequences should simply return the proper character.)

% \subsection{Lemma disambiguation}
% The mechanism which counts the occurrence of a same word in a same line is quite complex, because, when \LaTeX\ reads a command between a \cs{pstart} and a \cs{pend}, it does not know yet which are the line numbers.
% 
% The general mechanism is the following:
% \begin{itemize}
%    \item \textbf{At the first run}, each \cs{sameword} command increments an \Lpack{etoolbox} counter the name of which contains the argument of the \cs{sameword} commands.
%    \item Then this counter, associated with the argument of \cs{sameword} is stored,  with the \cs{@sw} command, in the auxiliary file of the current \Lpack{eledmac} section (the \verb+.1+, \verb+.2+… file).
%    \item \textbf{When this auxiliary file is read at the second run}, different operations are achieved:
%	\begin{enumerate} 
%       	\item  Get the rank of each \cs{sameword} in a line (relative rank) from the rank of each \cs{sameword} in all the numbered section (absolute rank):
%		      \begin{itemize}
%        		\item For each paired \cs{sameword} argument  and absolute line number, a counter is defined. Its value corresponds to the number of times  \verb+\sameword{argument}+  is called from the beginning of  the lineation to the end of the current line. We also store the same data for the preceding absolute line number, if it does not have \verb+\sameword{argument}+.    
%        		\item  For each \cs{sameword} having the same argument,  we substract from its absolute rank the number stored for the paired \cs{sameword} argument and previous absolute line number. Consequently, we obtain the relative rank.
%			       \item See the following example which explain how for same \cs{sameword} absolute ranks are transformed to relative rank.
%  \begin{verbatim}
%  At line 1:
%  absolute rank 1 becomes relative rank 1-0 = 1
%  1 is stored for this \sameword and the line 1
%  At line 2:
%  absolute rank 2 becomes relative rank 2-1 = 1
%  absolute rank 3 becomes relative rank 3-2 = 2
%  3 is stored for this \sameword and the line 2
%  At line 3:
%  no \sameword for this line.
%  3 is stored for this \sameword and the line 3
%  At line 4:
%  absolute rank 4 becomes relative rank 4-3 = 1  
%  3 is stored for this \sameword and the line 4
%  \end{verbatim}
%	       \end{itemize}
%        \item Create lists of lists of \cs{sameword} by depth of \cs{edtext}.
% That is: create a list for \cs{edtext} of level~1, a list for \cs{edtext} of level~2, a list for \cs{edtext} of level~3 etc.
% For each \cs{edtext} in these list, we store all the relative rank of \cs{saweword} which are called as lemma information, that is 1) or called in the first argument of \cs{sameword} 2) or called in the \cs{lemma} macro of the second argument of \cs{sameword} AND marked by the optional argument of \cs{saweword} in first argument of \cs{edtext}.
%
% For example, suppose a line with nested \cs{edtext}s which contains some 
% word marked by \cs{sameword} and having the following relative rank:\\
%
% 
%\let\up\textsuperscript
%bar\up{1} \fbox{%
%	    \fbox{foo\up{1} foo\up{2} bar\up{2} foo\up{3}} (A)(B)
%	    foo\up{4} bar\up{3}% 
%	 } (C)
%	 \fbox{%
%	    \fbox{foo\up{5}} (D)
%	    bar\up{4}
%	 } (E)
%
% In this example, all lemma information for \cs{edtext} is framed. The text in parenthesis is the content of critical notes associated to the preceding frame.
% As you can see, we have two level of \cs{edtext}.
%
%The list for \cs{edtext}s of level~1 is $\{\{1,2,2,3,4,3\},\{5,4\}\}$.
%
%The list for \cs{edtext}s of level~2 is $\{\{1,2,2,3\},\{5\}\}$.
%
% As you can see, the mandatory argument of \cs{sameword} does not matter: we store the rank informations for every word potentially ambiguous.
%       \end{enumerate}
%  \item At the second run, when a critical notes is called, we associate it to the next item of the list associated to is \cs{edtext} level. So, in the previous example:
%  \begin{itemize}
%      \item Critical notes (A) and (B) are associated with $\{1,2,2,3\}$.
%      \item Critical note (C) is associated with $\{1,2,2,3,4,3\}$.
%      \item Critical note (D) is associated with $\{5\}$.
%      \item Critical note (E) is associated with $\{5,4\}$.
%  \end{itemize}
%  \item At the second run, when a critical note is printed:
%    \begin{itemize}
%         \item The \cs{sameword} command is let  \cs{sameword@inedtext}. 
%	        \item At each call of this \cs{sameword@inedtext}, we step to the next element of the list associated to the note. Let it be $r$.
%	      \item For the word marked by \cs{sameword}, we calculate how many time it is called in its line. To do it:
%           \begin{itemize}
%            \item We get the absolute line number of the current \cs{sameword}. This absolute line number was stored with list of relative rank for the current \cs{edtext}. That means, in the previous example, that, if the absolute line number of \cs{edtext} was 1, that critical notes (A) and (B) were not associated with  $\{1,2,2,3\}$ but with $\{(1,1),(2,1),(2,1),(3,1)\}$. Such method to know the absolute line number associated to a \cs{sameword} is required because a \cs{edtext} can be overlap many lines, but \cs{sameword} can get it.
%            \item We get the value associated, when reading the auxiliary file, to the pair compose by the current marked word and the current absolute line number. Let this value be $n$.
%           \end{itemize}
%        \item If $n >1 $, that mean the current word appears more than once time in its line. In this case, we call \cs{showwordrank} with the word as first argument and $r$ as second argument. If the word is called only once, we just print it.
%   \end{itemize}
% \end{itemize} 
% After theory, implementation.
% \begin{macro}{\get@sw@txt}
% As the argument of \cs{sameword} can contain active character if we

% \begin{macro}{\autopar}
% In most cases it's only an annoyance to have to label the paragraphs
% to be numbered with \cs{pstart} and \cs{pend}. \cs{autopar} will
% do that automatically, allowing you to start a paragraph with its
% first word and no other preliminaries, and to end it with a blank line
% or a \verb"\par" command. The command should be issued within a
% group, after \cs{beginnumbering} has been used to start the
% numbering; all paragraphs within the group will be affected.
%
% A few situations can cause problems. One is a paragraph that begins with
% a begin-group character or command: \cs{pstart} will not get invoked
% until after such a group beginning is processed; as a result the
% character that ends the group will be mistaken for the end of the
% \cs{vbox} that \cs{pstart} creates, and the rest of the paragraph
% will not be numbered. Such paragraphs need to be started explicitly
% using \cs{indent}, \cs{noindent}, or \cs{leavevmode}---or \cs{pstart}, since
% you can still include your own \cs{pstart} and \cs{pend}
% commands even with \cs{autopar} on.
%
% Prematurely ending the group within which \cs{autopar} is in
% effect will cause a similar problem. You must either leave a
% blank line or use \verb"\par" to end the last paragraph before
% you end the group.
%
% The functioning of this macro is more tricky than the usual
% \cs{everypar}: we don't want anything to go onto the vertical
% list at all, so we have to end the paragraph, erase any evidence
% that it ever existed, and start it again using \cs{pstart}.
% We remove the paragraph-indentation box using \cs{lastbox} and
% save the width, and then skip backwards over the \cs{parskip}
% that's been added for this paragraph. Then we start again with
% \cs{pstart}, restoring the indentation that we saved, and
% locally change \verb"\par" so that it'll do our \cs{pend} for us.

% \section{Line number printing}
%
% \begin{macro}{\affixline@num}
% \cs{affixline@num} originally took a single argument, a series of
% commands for printing the line just split off by \cs{do@line}; it
% put that line back on the vertical list, and added a line number if
% necessary. It now just puts a left line number into \cs{l@dld@ta}
% or a right line number into \cs{l@drd@ta} if required.
%
% To determine whether we need to affix a line number to this line,
% we compute the following:
% \begin{tabbing}
%   \quad $m$ \=  \kill
%   $n$ \> $= \mbox{\it int\/} ( ( \mbox{\it linenum\/} -
%                              \mbox{\it firstlinenum\/} ) /
%                                \mbox{\it linenumincrement\/} )$ \\
%   $m$ \> $= \mbox{\it firstlinenum\/} +
%                   ( n \times \mbox{\it linenumincrement\/})$
% \end{tabbing}
% (where {\it int\/} truncates a real number to an integer).
% $m$ will be equal to {\it linenum\/} only
% if we're to paste a number on here.
% However, the formula breaks down for the first line to number (and any
% before that), so we check that case separately: if \cs{line@num} $\le$
% \cs{firstlinenum}, we compare the two directly instead of making these
% calculations.
%
% We compute, in the scratch counter \cs{@l@dtempcnta}, the number
% of the next line that should be printed with a number ($m$ in the
% above discussion), and move the current line number into the
% counter \cs{@l@dtempcntb} for comparison.
%
%
% First, the case when we're within a sub-line range.

% \label{footnotes}\relax
%
% The footnote macros are adapted from those in \PlainTeX, but they
% differ in these respects: the outer-level commands must add other
% commands to a list macro rather than doing insertions immediately;
% there are five separate levels of the footnotes, not just one; and there
% are options to reformat footnotes into paragraphs or into multiple
% columns.
%
% \subsection{Fonts}
% \label{fontcode}\relax
% Before getting into the details of formatting the notes, we set
% up some font macros. It is the notes that present the greatest
% challenge for our font-handling mechanism, because we need to be
% able to take fragments of our main text and print them in
% different forms: it is common to reduce the size,

% original font.

% \subsection{Normal footnote formatting} \label{sec:nfootformat}
%
% The processing of each note is done
% by four principal macros: the \cs{vfootnote} macro takes the text
% of the footnote and does the \cs{insert}; it calls on the
% \cs{footfmt} macro to select the right fonts, print the line
% number and lemma, and do any other formatting needed for that individual
% note. Within the output routine, the two other macros, \cs{footstart}
% and \cs{footgroup}, are called; the first prints extra vertical
% space and a footnote rule, if desired; the second does any reformatting
% of the whole set of the footnotes in this series for this page---such
% as paragraphing or division into columns---and then sends them to the
% page.
%
% These four macros, and the other macros and parameters shown
% here, are distinguished by the `series letter'
% that indicates which set of the footnotes
% we're dealing with---\texttt{A}, \texttt{B}, \texttt{C}, \texttt{D}, or \texttt{E}.
% The series letter always precedes the string \verb"foot" in macro
% and parameter names. Hence, for the \texttt{A} series, the four macros
% are called \cs{vAfootnote}, \cs{Afootfmt}, \cs{Afootstart},
% and \cs{Afootgroup}.
%
% \begin{macro}{\normalvfootnote}
% We now begin a series of commands that do `normal' footnote
% formatting: a format much like that implemented
% in \PlainTeX{}, in which each footnote
% is a separate paragraph.
%
% \cs{normalvfootnote} takes the series letter as \verb"#1",
% and the entire text of the footnote is \verb"#2". It does the
% \cs{insert} for this note, calling on the \cs{footfmt} macro for
% this note series to format the text of the note.

% To simplify the logic, we use a lot of counters to tell us which

% \item \cs{@ssub} for starting sub-line;
% \item \cs{@elin} for ending line;

% \end{itemize}
% There's no counter for the line number because it's always printed.

% \cs{normalfootstart}
% is a standard footnote-starting macro, called in the output
% routine whenever there are footnotes of this series to be
% printed: it skips a bit and then draws a rule.
%
% Any \verb"footstart" macro must put onto the page something that
% takes up space exactly equal to the \verb"\skip\footins" value for
% the associated series of notes. \TeX\ makes page computations based
% on that \cs{skip} value, and the output pages will suffer from
% spacing problems if what you add takes up a different amount of
% space.
%
% But if the skip \verb|\preXnotes@| is greater than 0~pt,
% it's used instead of \verb"\skip\footins" for the first printed series.
%
% The \cs{leftskip} and \cs{rightskip} values
% are both zeroed here.\phantomsection\label{footskips}
% Similarly, these skips are cancelled in the \verb"vfootnote" macros
% for the various types of notes. Strictly speaking,
% this is necessary only
% if you are using paragraphed footnotes, but we have put it here
% and in the other \verb"vfootnote" macros too so that the behavior of
% \Eledmac{} in this respect is general across all footnote types
% (you can change this).  What this means is that any \cs{leftskip}

% \subsection{Standard footnote definitions}
%
% \begin{macro}{\footnormal}
% We can now define all the parameters for the six series of
% footnotes; initially they use the `normal' footnote formatting,
% which is set up by calling \cs{footnormal}.
% You can switch to another type of formatting by using
% \cs{footparagraph}, \cs{foottwocol}, or \cs{footthreecol}.
%
% Switching to a variation of `normal'
% formatting requires changing the
% quantities defined in \cs{footnormal}.  The best way to
% proceed would be to make a copy of this macro, with a different
% name, make your desired changes in that copy, and then invoke it,
% giving it the letter of the footnote series you wish to control.
%
% (We have not defined baseline skip values like
% \cs{abaselineskip}, since this is one of the quantities set in
% \cs{notefontsetup}.)
%
% What we want to do here is to say something like the following
% for each footnote series. (This is an example, not part of the
% actual \Eledmac{} code.)
% \begin{verbatim}
% \skip\Afootins=12pt plus5pt minus5pt
% \count\Afootins=1000
% \dimen\Afootins=0.8\vsize
% \let\vAfootnote=\normalvfootnote  \let\Afootfmt=\normalfootfmt
% \let\Afootstart=\normalfootstart  \let\Afootgroup=\normalfootgroup
% \let\Afootnoterule=\normalfootnoterule
% \end{verbatim}
% Instead of repeating ourselves, we define a \cs{footnormal}
% macro that makes all these assignments for us, for any given
% series letter.  This also makes it easy to change from any
% different system of formatting back to the \verb"normal" setting.

%
% \subsection{Paragraphed footnotes}
%
% The paragraphed-footnote option
% reformats all the footnotes of one series for a page into
% a single paragraph; this is especially appropriate when the notes are
% numerous and brief. The code is based
% on \thetexbook, pp.\,398--400, with
% alterations for our environment. This algorithm uses a considerable
% amount of save-stack space: a \TeX\ of ordinary size may not be able
% to handle more than about $100$ notes of this kind on a page.
%
% \begin{macro}{\footparagraph}
% The \cs{footparagraph} macro
% sets up everything for one series of the footnotes so that
% they'll be paragraphed; it takes the series letter as argument.
% We include the setting of \verb"\count\footins" to $1000$ for the
% footnote series just in case you are switching to paragraphed
% footnotes after having columnar ones, since they change this
% value (see below).
%
% It is important to call \cs{footparagraph} only after
% \cs{hsize} has been set for the pages that use
% this series of notes; otherwise \TeX\ will try to put too
% many or too few of these notes on each page. If you need to
% change the \cs{hsize} within the document, call
% \cs{footparagraph} again afterwards to take account of the new
% value.  The argument of \cs{footparagraph} is the letter
% (\texttt{A}--\texttt{E}) denoting the series of notes to be paragraphed.

%
% \begin{macro}{\para@vfootnote}
% \cs{para@vfootnote}
% is a version of the \cs{vfootnote} command that's used for
% paragraphed notes.  It gets appended to the \cs{inserts@list} list
% by an outer-level footnote command like \cs{Afootnote}.  The first
% argument is the note series letter; the second is the full text
% of the printed note itself, including line numbers, lemmata, and
% footnote text.
%
% The initial model for this insertion is, of course, the
% \verb"\insert\footins" definition in \thetexbook, p.\,398.
% There, the footnotes are first collected up in hboxes, and these
% hboxes are later unpacked and stuck together into a paragraph.
%
% However, Michael Downes\index{Downes, Michael} has pointed out
% that because text in hboxes gets typeset in restricted horizontal
% mode, there are some undesirable side-effects if you later want
% to break such text across lines.  In restricted horizontal mode,
% where \TeX\ does not expect to have to break lines, it does not
% insert certain items like \cs{discretionary}s. If you later unbox
% these hboxes and stick them together, as the \texbook{}
% macros do to make these footnotes, you lose the ability to
% hyphenate after an explicit hyphen.  This can lead to overfull
% \cs{hbox}es when you would not expect to find them, and to the
% uninitiated it might be very hard to see why the problem had
% arisen.\footnote{Michael Downes, `Line Breaking in \cs{unhbox}ed
% Text', \textit{TUGboat} \textbf{11} (1990), pp.\,605--612.}
%
% Wayne Sullivan\index{Sullivan, Wayne} pointed out to us another
% subtle problem that arises from the same cause: \TeX\ also leaves
% the \cs{language} whatsit nodes out of the horizontal
% list.\footnote{See \thetexbook, p.\,455 (editions after
% January 1990).}  So changes from one language to another will not
% invoke the proper hyphenation rules in such footnotes.  Since
% critical editions often do deal with several languages,
% especially in a footnotes, we really ought to get this bit of code
% right.
%
% To get around these problems, Wayne suggested emendations to the
% \texbook{} versions of these macros which are broadly the
% same as those described by Michael: the central idea (also
% suggested by Donald Knuth in a letter to Michael) is to avoid collecting
% the text in an \cs{hbox} in the first place, but instead to collect
% it in a \cs{vbox} whose width is (virtually)
% infinite.\phantomsection\label{hboxproblem} The text is therefore typeset in
% unrestricted horizontal mode, as a paragraph consisting of a
% single long line.  Later, there is an extra level of unboxing to
% be done: we have to unpack the \cs{vbox}, as well as the hboxes
% inside it, but that's not too hard.  For details, we refer you to
% Michael's article, where the issues are clearly
% explained.\footnote{Wayne supplied his own macros to do this, but
% since they were almost identical to Michael's, we have used the
% latter's \cs{unvxh} macro since it is publicly
% documented.}  Michael's unboxing macro is called \cs{unvxh}: unvbox,
% extract the last line, and unhbox it.
%
% Doing things this way has an important
% consequence:\phantomsection\label{nobreaks-detail} as Michael
% pointed out, you really can't put an explicit line-break into a
% note built in a \cs{vbox} the way we are doing.\footnote{`Line
% Breaking', p.\,610.}  In other words, be very careful not to say
% \cs{break}, or \verb"\penalty-10000", or any equivalent inside your
% para-footnote.\phantomsection\label{nobreak}  If you do, most of the note will
% probably disappear.  You \emph{are} allowed to make strong
% suggestions; in fact \verb"\penalty-9999" will be quite okay.  Just
% don't make the break mandatory.  We haven't applied any of
% Michael's solutions here, since we feel that the problem is
% exiguous, and \Eledmac{} is quite baroque enough already.  If
% you think you are having this problem, look up Michael's
% solutions.

% One more thing; we set \cs{leftskip} and \cs{rightskip} to zero.

% the assumption that the notes are \cs{hsize} wide.
%
% So, finally, here is the modified foot-paragraph code, which
% sets the footnote in vertical mode so that language and

% those occasions when \TeX\ attempts to split foot paragraphs.
% After trying out such a split (see \thetexbook, p.\,124),
% \TeX\ inserts a penalty of $-10000$ here, which
% nearly always forces the break at the end of the whole footnote
% paragraph (since individual notes can't be split) even when this
% leads to an overfull vbox.  The change above results in a penalty
% of $0$ instead which allows, but doesn't force, such breaks. This
% penalty of $0$ is later removed, after page breaks have been
% decided, by the \cs{unpenalty} macro in \cs{makehboxofhboxes}. So it
% does not affect how the footnote paragraphs are typeset (the
% notes still have a penalty of $-10$ between them, which is added
% by \cs{parafootfmt}).

%
% We set the \cs{count} of the foot insert to $333$.
% Each footnote can be thought of as contributing only one third of
% its height to the page, since the footnote insertion has been
% made as a long narrow column, which then gets trisected by the
% \cs{rigidbalance} routine (inside \cs{threecolfootgroup}).
% These new, shorter columns are saved in a box, and then that box
% is \emph{put back} into the footnote insert, replacing the
% original collection of the footnotes.  This new box is, therefore,
% only about a third of the height of the original one.
%
% The \cs{dimen} value for this note series has to change in the
% inverse way: it needs to be three times
% the actual limit on the amount of space these notes are allowed to
% fill on the page, because when \TeX\ is
% accumulating material for the page

% is, say, 10\,cm, then each column will be $0.3\times10=3$\,cm
% wide, leaving a gap of 1\,cm spread equally between columns
% (i.e., .5\,cm between each).

% and \LaTeX\ provides a single numbered footnote. The \Eledmac{} package
% uses the \edmac{} mechanism to provide six series of numbered footnotes.
% 
%    First, though, the \Lpack{footmisc} package has an option whereby
% two or more consecutive \cs{footnote}s have their marks separated
% by commas. This seems such a useful ability that it is provided
% automatically by \Eledmac. 
%
% \begin{macro}{\multiplefootnotemarker}
% \begin{macro}{\multfootsep}

% are provided by the \Lpack{footmisc} package and perhaps
% by other footnote packages.

% \section{Specific skip for first series of footnotes}
% \cs{beforeXnotes} insert a specific skip for the first series of notes in a page.
% As we can know in advance which series will be the first, we call \cs{prepare@preXnotes} before inserting any critical notes, in order to prevent page number overlapping. 
% \begin{enumerate}
%   \item If it is the first note of the current page, it changes the footnote skip for the series to the value specified to \cs{beforeXnotes}. Keeps the series of the note as the first one of the current page.
%   \item If it is not the first note of the current page:
%   \begin{itemize}
%     \item If the current series is printed after the series kept as the first of the current page, then nothing happens.
%     \item If the current series is printed before the series kept as the first of the current page, then it changes the footnote of the current series to the value normally used by the series which was marked as the first of the page. Keeps the current series as the new first one of the current page.
%   \end{itemize}
% \end{enumerate}
% 
%
% For example, suppose the series order is A,B. We call first a \cs{Bfootnote} and a \cs{Afootnote}. The only skips used are, finally, the skip specific to the first series of the page, and the skip for the B series. If we have not called \cs{Afootnote}, the only skip used is the skip specific to the first series of the page.
% 
% That is perfect. 
%
%
% The series skip and the first series of the current page are reset before the footnotes are printed. Then, the footstart macros manage the problem of the first series of the page.
%
% After the rule, the space which is defined by \cs{afterXrule} does not depend on whether the series is the first one of the page or not. So we use its normal value for each series.

% \begin{macro}{\setprintendlines}
% The \cs{printendlines} macro is similar to \cs{printlines} but is
% for printing endnotes rather than footnotes. 
%
%    The principal difference between foot- and endnotes is that footnotes
% are printed on the page where they are specified but endnotes
% are printed at a different point in the document. We need an indication
% of the source of an endnote; \cs{setprintendlines} provides this
% by always printing the page number. The coding is slightly simpler than
% \cs{setprintlines}.
%
% First of all, we print the second page number only if
% the ending page number is different
% from the starting page number.\phantomsection\label{printendlines}

% The \cs{Xendnote} macro functions to
% write one endnote to the \file{.end} file. We change
% \cs{newlinechar} so that in the file every space becomes the
% start of a new line; this generally ensures that a long note doesn't
% exceed restrictions on the length of lines in files.

% \cs{Xendnote}  commands called \cs{Xend} commands on to the endnote file; these are analogous to the various
% \verb"footfmt" commands above, and they take the same arguments.
% When we process this file, we want to pick out the notes of one
% series and ignore all the rest. To do that, we equate the \verb"end"
% command for the series we want to \cs{endprint}, and leave the
% rest equated to \cs{@gobblefive}, which just skips over its five
% arguments.

% \end{macro}
%
%
%
% The next portion is probably the trickiest part of moving from
% TeX to \LaTeX\. The original code is below, but we need 
% something very different. 
%
% This is a new output routine, with changes to handle printing all our
% footnotes. Those changes have not been added directly, but are in macros
% that get called here: that should make it easier to see what would need
% to be taken over to a different output routine. We continue to use the
% \cs{pagebody}, \cs{makeheadline}, \cs{makefootline}, and \cs{dosupereject}
% macros of \PlainTeX; for those macros, and the original version of
% \cs{output}, see \thetexbook, p.\,364.

% \cs{do@feet} ships out all the footnotes. Standard \edmac{} has only
% five feet, but there is nothing in principal to prevent you
% from creating an arachnoid or centipedal edition; straightforward
% modifications of \edmac{} are all that's required. However, the
% myria\-pedal edition is ruled out by  eTeX limitations: the number
% of insertion classes is limited to $2^16$.
%
%
%    With luck we might only have to change \cs{@makecol} and
% \cs{@reinserts}. The kernel
% definition of these, and perhaps some other things, is:

% \section{Cross referencing}
% \label{xref}\relax
%
%    Peter Wilson has rewritten portions of the code in this section so that
% the LaTeX \file{.aux} file is used. This will also handle \cs{include}d
% files.
%
%    Further, I have renamed some of the original \edmac{} macros so that
% they do not clash with the LaTeX label/ref commands (\edmac{} and LaTeX
% use very different mechanisms). In particular,
% the original \edmac{} \cs{label} and \cs{pageref} have been renamed
% as \cs{edlabel} and \cs{edpageref} respectively.
% 
%
% You can mark a place in the text using a command of the form
% \verb"\edlabel{foo}", and later refer to it using the label
% \verb"foo" by saying \verb"\edpageref{foo}", or \verb"\lineref{foo}" or
% \verb"\sublineref{foo}". These reference commands will produce,
% respectively, the page, line and sub-line on which the
% \verb"\edlabel{foo}" command occurred.
%
% The reference macros warn you if a reference is made to an
% undefined label. If \verb"foo" has been used as a label before,
% the \verb"\edlabel{foo}" command will issue a complaint; subsequent
% \cs{edpageref} and \cs{edlineref} commands will refer to the
% latest occurrence of \verb"\label{foo}".
%
% \begin{macro}{\labelref@list}

% creates a dummy entry), and pops the next value for the current
% label, storing it in \cs{label@refs}. Finally it defines the
% label to be \cs{empty} so that any future check will turn up
% the fact that it has been used.\footnote{The remaining macros
% in this section were kindly revised by Wayne
% Sullivan,\index{Sullivan, Wayne}  who
% substantially improved their efficiency and flexibility.}

%
%
%    The following is borrowed, and renamed, from the \Lpack{amsmath}
% package. See also the CTT thread `eeq and amstex', 1995/08/31, started
% by Keith Reckdahl and ended definitively by David M. Jones.
%
%
% Several of the [math] macros scan their body twice. This means we must 
% collect all text in the body of an environment form before calling
% the macro.
%
% \begin{macro}{\@emptytoks}
% This is actually defined in the \Lpack{amsgen} package.
%    \begin{macrocode}
\newtoks\@emptytoks

%    \end{macrocode}
% \end{macro}
%
% The rest is from \Lpack{amsmath}.
%
% \begin{macro}{\l@denvbody}
% A token register to contain the body.
%    \begin{macrocode}
\newtoks\l@denvbody

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\addtol@denvbody}
% |\addtol@denvdody{arg}| adds |arg| to the token register |\l@denvbody|.
%    \begin{macrocode}
\newcommand{\addtol@denvbody}[1]{%
  \global\l@denvbody\expandafter{\the\l@denvbody#1}}

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\l@dcollect@body}
% The macro |\l@dcollect@body| starts the scan for the |\end{...}| command
% of the current environment. It takes a macro name as argument. This macro
% is supposed to take the whole body of the environment as its argument.
% For example, given |cenv#1{...}| as a macro that processes |#1|, then
% the environment form, |\begin{env}| would call |\l@dcollect@body\cenv|.
%

  \ifx\end#2\else b\expandafter\l@dpush@begins\fi}

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\l@dcollect@@body}
% |\l@dcollect@@body| takes two arguments: the first will consist of all text
% up to the next |\end| command, and the second will be the |\end| command's
% argument. If therte are any extra |\begin| commands in the body text, 
% a marker is pushed onto a stack by the |l@dpush@begins| function. 
% Empty state for this stack means we have reached the |\end| that matches 
% our original |\begin|. Otherwise we need to include the |\end| and its 
% argument in the material we are adding to the environment body accumulator.
%    \begin{macrocode}
\def\l@dcollect@@body#1\end#2{%

% \subsection{New commands : \cs{eledxxx}}
% The new system of \cs{eledxxxx} commands to section text work like this:
% \begin{enumerate}
%     \item When one of these commands is called, \Lpack{eledmac} writes to an auxiliary files:
%      \begin{itemize}
%           \item The section level.
%           \item The section title.
%           \item The side (when \Lpack{eledpar} is used).
%           \item The pstart where the command is called.
%           \item If we have starred version or not.
%      \end{itemize}
%   \item \Lpack{eledmac} adds the title of the section to pstart, as  normal content. This is to enable critical notes.
%   \item When \LaTeX\ is run a other time, this file is read. That:
%     \begin{itemize}
%         \item Adds the pstart number to a list of pstarts where a sectioning command is used.
%         \item Defines a command, the name of which contains the pstart number, and which calls the normal \LaTeX\ sectioning command.
%     \end{itemize}
%   \item This last command is called when the pstart is effectively printed.
% \end{enumerate}
%
% We do not define commands for \cs{eledsection} and related if the \verb+noeledsec+ option is loaded.
% We use etoolbox tests and not the \verb+\ifxxx…\else…\fi+ structure to prevent problem of expansions with command after the \verb+\ifxxx+ which contains \verb+fi+.

% \section{Some things to do when changing version}
% \subsection{Migrating from edmac} \label{sec:lastuser}
%
% If you have never used \edmac, ignore this section. If you have used
% \edmac{} and are starting on a completely new document, ignore this section.
% Only read this section if you are converting an original \edmac{}
% document to use \eledmac.
%
%    The package still provides the original \cs{text} command, but it is
% (a) deprecated, and 
% (b) its name has been changed\footnote{A name like \cs{text} is  likely to be defined by
% other \LaTeX\ packages (it certainly is by the AMS packages) and it
% seems sensible to try and avoid clashes with other definitions.} 
% to \cs{critext}; 
% use the \cs{edtext} macro instead. However, if you do
% use \cs{critext} (the new name for \cs{text}), the following is a reminder.
%
%
% \DescribeMacro{\critext}
% Within numbered paragraphs, footnotes and endnotes are generated
% by forms of the \cs{critext} macro:
% \begin{verse}
% \cs{critext}\marg{lemma}\meta{commands}\verb"/"
% \end{verse}
%
%
% The \meta{lemma} argument is the lemma in the main text: \cs{critext}
% both prints this as part of the text, and makes it available to the
% \meta{commands} you specify to generate notes. The \verb"/" at the
% end terminates the command; it is part of the macro's definition so
% that spaces after the macro will be treated as significant.
%
% For example:
% \egstart
% \begin{verbatim}
% I saw my friend \critext{Smith}
% \Afootnote{Jones C, D.}/
% on Tuesday.
% \end{verbatim}
% \egmid
% 1\enspace I saw my friend\\
% 2\enspace Smith on Tuesday.\smallskip
% \hrule width 1.5cm
% \strut {\bf 2} Smith] Jones C, D.
% \egend
%
% The lemma \verb"Smith" is printed as part of this sentence in
% the text, and is also made available to the footnote
% that specifies a variant, \verb"Jones C, D". The footnote macro
% is supplied with the line number at which the lemma appears
% in the main text.
%
% The \meta{lemma} may contain further \cs{critext} commands.
%  Nesting makes
% it possible to print an explanatory note on a long passage together with
% notes on variants for individual words within the passage. For
% example:
% \egstart
% \begin{verbatim}
% \critext{I saw my friend
%   \critext{Smith}{\Afootnote{Jones
%   C, D.}/ on Tuesday.}
%   \Bfootnote{The date was
%   July 16, 1954.}
% /
% \end{verbatim}
% \egmid
% 1\enspace I saw my friend\\
% 2\enspace Smith on Tuesday.\smallskip
% \hrule width 1.5cm
% \strut {\bf 2} Smith] Jones C, D.\smallskip
% \hrule width 1.5cm
% \strut {\bf 1--2} I saw my friend \\
% Smith on Tuesday.] The\\ date was
% July 16, 1954.
% \egend
%
% However, \cs{critext} cannot handle overlapping but unnested
% notes---for example, one note covering lines 10--15, and another
% covering 12--18; a \cs{critext} that starts in the \meta{lemma}
% argument of another \cs{critext} must end there, too. (The
% \cs{lemma} and \cs{linenum} commands may be used to
% generate overlapping notes if necessary.)
%
% The second argument of the \cs{critext} macro, \meta{commands},
% is the same as the second argument to the \cs{edtext} macro.
%
%
% It is possible to define aliases for \cs{critext}, which
% can be easier to type. You can make a single character substitute
% for \cs{critext} by saying this:
% \begin{verbatim}
% \catcode`\<=\active
% \let<=\critext
% \end{verbatim}
%
% Then you might say \verb"<{Smith}\variant{Jones}/". This of course
% destroys the ability to use \verb"<" in any new macro definitions, so
% long as it remains in effect; hence it should be used with care.
%
% Changing the character at the end of the command requires more work:
% \begin{verbatim}
% \catcode`\<=\active
% \def\xtext#1#2>{\critext{#1}{#2}/}
% \let<=\xtext
% \end{verbatim}
% This allows you to say \verb"<{Smith}\Afootnote{Jones}>".
%
% Aliases for \cs{critext}
% of the first kind shown here also can't be nested---that is,
% you can't use the alias in the text that forms the first argument
% to \cs{critext}. (See section~\ref{text} to find out why.) Aliases of
% the second kind may be nested without any problem.
%
%
% If you really have to use |\critext| in any of the tabular or

% \subsection{Migration from ledmac to eledmac}\label{migration}
% In eledmac, some changes were made in the code to allow for easy customization.
% This can cause problems for people who have made their own customizations. The next sections explain how to correct this.
%
%
% If you have created your own series using \cs{addfootins} and \cs{addfootinsX}, you should use instead the \cs{newseries} command (see \reff{newseries}). You must remove your \cs{Xfootnote} command.
%
% If you have customized the \cs{XXXXXXfmt} command, you should check if commands for display options (\reff{displayoptions}) and options in \cs{Xfootnote} (\reff{Xfootnoteopt}) cannot do the same thing. If not, you can add a new ticket in Github to request a new function for doing this.\footnote{\url{https://github.com/maieul/ledmac/issues}}
%
% If for some reason you do not want to make the modifications to use eledmac new functions, you can continue using your own \cs{XXXXXfmt} command, but you must replace:
% \begin{verbatim}
% \renewcommand*{XXXXfmt}[3]
% \end{verbatim}
% with
% \begin{verbatim}
% \renewcommandx*{XXXXfmt}[4][4=Z]
% \end{verbatim}
% If you dont' do that, you will see a spurious \verb+[X]+, where X is series letter.
%
% If you used a \cs{protect} command inside a \cs{footnote} command inside a numbered section, you must change the \cs{protect} to \cs{noexpand}. If you don't, the command after the \cs{protect} won't be displayed.
% \subsection{Migration to eledmac 1.5.1}\label{change151}
% The version 1.5.1 corrects a bug with \verb+stanzaindentsrepetition+ (cf. \reff{stanzaindentsrepetition}). This bug had two consequences:
% \begin{enumerate}
% \item \verb+stanzaindentsrepetition+ didn't work when its value was greater than 2.
% \item \verb+stanzaindentsrepetition+ worked wrong when its value was equal to 2.
% \end{enumerate}
% 
% So, if you used \verb+stanzaindentsrepetition+ with value equal to 2, you must change your \cs{setstanzaindents}. Explanation:
% \begin{verbatim}
% \setcounter{stanzaindentsrepetition}{2}
% \setstanzaindents{5,1,0}
% \end{verbatim}
% This code, in a version older than 1.5.1, made that the first verse had an indent of 0, the secund verse of 1, the third verse of 0, the fourth verse of 1 etc.
%
% But instead the code should have assigned the reverse: the first verse had an indent of 1, the secund verse of 0, the third verse of 1, the fourth verse of 0 etc.
%
% So version 1.5.1 corrected this bug. If you want to keep the older presentation, you must change:
% \begin{verbatim}
% \setcounter{stanzaindentsrepetition}{2}
% \setstanzaindents{5,1,0}
% \end{verbatim}
% by:
% \begin{verbatim}
% \setcounter{stanzaindentsrepetition}{2}
% \setstanzaindents{5,0,1}
% \end{verbatim} 
% \subsection{Migration to eledmac 1.12.0}
% The migration to eledmac 1.12.0 is easy:
% \begin{itemize}
%    \item You must delete all the auxiliary files, and so one, make the normal three runs.
%    \item If you have modified \cs{l@reg}, which is not advisable, you must rename it to \cs{@nl@reg}.
% \end{itemize}
%
% Anyway, there is another problem. If you have text in brackets just after \cs{pstart} or \cs{pend}, the text will be considered an optional argument of \cs{pstart} or \cs{pend} (see \reff{pstart:optionalarg}). 
% In this case, just add a \cs{relax} between \cs{pstart}/\cs{pend} and the brackets.

% The version 1.12.0 adds a new better way to manage section titles inside numbered text. Please read §~\ref{eledsection} (\reff{eledsection}).
% \subsection{Migration to eledmac 17.1}
% The version change the default behavior of \cs{pstartinfootnote}. 
% Henceforth, the pstart will be printed if footnote only for the section of text where you have called \cs{numberpstarttrue}.

% We don't see any reason to print it in other section. However, if you want to print the pstart number in all footnote, with or without \cs{numberpstarttrue}, you can use 
% \cs{pstartinfootnoteeverytime}.
% \subsection{Migration to eledmac 1.21.0}
% \subsubsection{\cs{Xledsetnormalparstuff} and \cs{ledsetnormalparstuffX}}
% The \cs{ledsetnormalparstuff} has been split in two different commands:
% \begin{itemize}
%  \item \cs{Xledsetnormalparstuff} for critical notes;
%  \item \cs{ledsetnormalparstuffX} for familiar notes.
% \end{itemize}
% The new commands take an optional argument which is the series letter.
% If you have redefined \cs{ledsetnormalparstuff} or commands which call them, you must make the appropriate change
% \subsubsection{Endnotes}
% In any case, clean the \verb+.end+ file before the next run.
%
% \label{oldprintnpnumspace} The previous version of \Eledmac{} had a bug: there were two spaces between the start page number and the start line number, but only one space between the end page number and the end line number.
%
% Indeed, a spurious space was added after the first \cs{printnpnum}.
% This spurious space has been deleted. 
% However, if you want to keep the previous spurious space, just load the package with the \verb+oldprintnpnumspace+ option.
%
% If you have redefined \cs{endprint}, you must:
% \begin{itemize}
%  \item Contact us to ask for the feature that required your hack, in order to avoid such a hack in the future.
%  \item Use the new fifth argument.
%  \item Add \verb+\xdef\@currentseries{#4}+ at the beginning of your own command.
% \end{itemize}
% \subsection{Migration to eledmac 1.22.0}
% The \cs{ledinnote} commands takes now a first optional argument, which is the label for the hyperreference.
% If you have redefined it, change your redefinition, and check if you can 
% avoid this redefinition by redefining only \cs{ledinnotemark}.
% \subsection{Migration to eledmac 1.23.0}
% People must delete the numbered auxiliary file before new run after update of eledmac.
