+% \section{Introduction}
+%
+%    The \edmac{} macros \cite{EDMACTUG} for typesetting critical editions 
+% of texts
+% have been available for use with TeX for some years. Since \edmac{}
+% became available there had been a small but constant demand for a
+% version of \edmac{} that could be used with \LaTeX. The \Eledmac{}
+% package was introduced in 2003 in an attempt to satisfy that request.
+% 
+%    Some critical editions contain texts in more than one form, such as
+% a set of verses in one language and their translations in another. In
+% such cases there is a desire to be able to typeset the two texts, together
+% with any critical apparatus, in parallel. The \Eledpar{} package
+% is an extension to \Eledmac{} that enables two texts and their
+% apparatus to be set in parallel, either in two columns or on pairs of
+% facing pages.
+%
+%    The package has to try and coerce \TeX{} into paths it was not designed
+% for. Use of the package, therefore, may produce some surprising results.
+%
+% This manual contains a general description of how to use 
+% \Eledpar{} starting in section~\ref{howto};
+% the complete source code for the package,
+% with extensive documentation (in sections~\ref{overview}
+% through \ref{end}); 
+% and an Index to the source code. As \Eledpar{} is an adjunct to \Eledmac{}
+% I assume that you have read the \Eledmac{} manual. Also \Eledpar{} requires
+% \Eledmac{} to be used, preferably at least version 0.10 (2011/08/22).
+% You do not need to  read the source code for this package in order to 
+% use it but doing so may help to answer any questions you might have.
+% On a first reading,
+% I suggest that you should skip anything after the general documentation in
+% sections~\ref{howto} until~\ref{overview}, 
+% unless you are particularly interested in the innards of \Eledpar.
+%
+%
+% \section{The \Lpack{\eledpar} package}\label{howto}
+%
+% 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.
+%
+% The \Eledpar{} package lets you typeset two \emph{numbered} texts in
+% parallel. This can be done either as setting the `Leftside' and `Rightside'
+% texts in two columns or on facing pages.
+% In the paired pages case footnotes are placed at the bottom of the page
+% on which they are called out --- that is, footnotes belonging to the left
+% are set at the foot of a left (even numbered) page, and those for right
+% texts are at the bottom of the relevant right (odd numbered) page. However,
+% in the columnar case, all footnotes are set at the bottom left of the 
+% page on which they are called out --- they are not set below the 
+% relevant column. 
+% The line numbering schemes need not be the same for the two texts.
+%
+% \subsection{General}
+%
+% \Eledmac{} essentially puts each chunk of numbered text 
+% (the text within a \cs{pstart} \ldots \cs{pend}) into a box and then 
+% following the \cs{pend} extracts the text line by line from the box 
+% to number and print it. More precisely, the text is first put into the
+% the box as though it was being typeset as normal onto a page and
+% any notes are stored without being typeset. Then each typeset line 
+% is extracted from the box and any notes for that line are recalled.
+% The line, with any notes, is then output for printing, possibly with
+% a line number attached. Effectively, all the text is typeset and then
+% afterwards all the notes are typeset.
+% 
+%
+% \Eledpar{} similarly puts the left and right chunks into boxes but can't 
+% immediately output the text after a \cs{pend} --- it has to wait until
+% after both the left and right texts have been collected before it can 
+% start processing. This means that several boxes are required and possibly
+% TeX has to store a lot of text in its memory; both the number of potential
+% boxes and memory are limited. If TeX's memory is overfilled the recourse is
+% to reduce the amount of text stored before printing.
+%
+% \DescribeMacro{\maxchunks}
+% It is possible to have multiple chunks in the left and right texts before
+% printing them. The macro \cs{maxchunks}\marg{num} specifies the maximum
+% number of chunks within the left or right texts. This is initially set as: \\
+% \verb?\maxchunks{5120}? \\
+% meaning that there can be up to 5120 chunks in the left text and up to 
+% 5120 chunks in 
+% the right text, requiring a total of 10240 boxes. If you need more chunks
+% then you can increase \cs{maxchunks}. The \cs{maxchunks} must be called in the preamble.
+%
+% If you \cs{maxchunks} is too little
+%you can get a \Eledmac{} error message along the
+% lines: `Too many \cs{pstart} without printing. Some text will be lost.'
+% then you will have to either increase \cs{maxchunks} or use the
+% parallel printing commands (\cs{Columns} or \cs{Pages}) more frequently.
+%
+% When typesetting verse using \cs{syntax}, each line is treated as a chunk,
+% so be warned that if you are setting parallel verses you might have to 
+% increase \cs{maxchunks} much more than it appears at first sight.
+%
+%    In general, \Eledmac{} is a TeX resource hog, and \Eledpar{} only 
+% makes things worse in this respect.
+%
+% \section{Parallel columns}\label{columns}
+%
+% \DescribeEnv{pairs}
+% Numbered text that is to be set in columns must be within a \verb?pairs?
+% environment. Within the environment the text for the lefthand and righthand
+% columns is placed within the \verb?Leftside? and \verb?Rightside? 
+% environments, respectively; these are described in more detail below
+% in section~\ref{leftright}.
+%
+% \DescribeMacro{\Columns}
+% The command \cs{Columns} typesets the texts in the previous pair of
+% \verb?Leftside? and \verb?Rightside? environments. 
+% The general scheme for parallel columns looks like this:
+% \begin{verbatim}
+% \begin{pairs}
+% \begin{Leftside} ... \end{Leftside}
+% \begin{Rightside} ... \end{Rightside}
+% \end{pairs}
+% \Columns
+% \begin{pairs}
+% \begin{Leftside} ... \end{Leftside}
+% ...
+% \end{pairs}
+% \Columns
+% \end{verbatim}
+%
+%
+% Keep in mind that the \cs{Columns} \textbf{must be} outside of the \verb+pairs+ environment.
+% \DescribeMacro{\AtBeginPairs}
+% \changes{v1.9.0}{2014/09/16}{Add \cs{AtBeginPairs} macro.}
+% You can use the macro \cs{AtBeginPairs} to insert a code at the begining of each \verb+pairs+ environments.
+% That could be useful to add the \cs{sloppy} macro to prevent overfull hboxes in two columns.
+% \begin{verbatim}
+% \AtBeginPairs{\sloppy}
+% \end{verbatim}
+% There is no required pagebreak before or after the columns.
+%
+% \DescribeMacro{\Lcolwidth}
+% \DescribeMacro{\Rcolwidth}
+% The lengths \cs{Lcolwidth} and \cs{Rcolwidth} are the widths of the left
+% and right columns, respectively. By default, these are: \\
+% \verb?\setlength{\Lcolwidth}{0.45\textwidth}? \\
+% \verb?\setlength{\Rcolwidth}{0.45\textwidth}? \\
+% They may be adjusted if one text tends to be `bulkier' than the other.
+%
+% \DescribeMacro{\columnrulewidth}
+% \DescribeMacro{\columnseparator}
+% The macro \cs{columnseparator} is called between each left/right pair
+% of lines. By default it inserts a vertical rule of width 
+% \cs{columnrulewidth}. As this is initially defined to be 0pt the rule
+% is invisible. For a visible rule between the columns you could try: \\
+% \verb?\setlength{\columnrulewidth}{0.4pt}? \\
+% You can also modify \cs{columnseparator} if you want more control.
+%
+% \DescribeMacro{\columnsposition}
+% \changes{v1.8.0}{2014/08/05}{Add \cs{columnsposition}.}
+% By default, columns are positioned to the right of the page.
+% However, you use \cs{columnsposition}\verb+{L}+ to align them to the left,
+% or \cs{columnsposition}\verb+{C}+ to center them.
+%
+% When you use \cs{stanza}, the visible rule may shift when a verse has a hanging indent. To prevent shifting, use \cs{setstanzaindents} outside the \verb|Leftside| or \verb|Rightside| environment.
+%
+%
+% \DescribeMacro{\beforecolumnseparator}\DescribeMacro{\aftercolumnseparator}
+% \changes{v1.8.0}{2014/08/05}{Add \cs{beforecolumnseparator} and \cs{aftercolumnseparator}.}
+% By default, the spaces around column separator are the same as the space:
+% \begin{itemize}
+%  \item On the left of columns, if columns are aligned right.
+%  \item On the right of columns, if columns are aligned left.
+%  \item On both the Left and Right columns, if columns are centered.
+% \end{itemize}
+% You can redefine \cs{beforecolumnseparator} and \cs{aftercolumnseparator} length to define spaces before or after the column separator, instead of letting eledpar calculate them automatically. 
+% \begin{verbatim}
+% \setlength{\beforecolumseparator}{length}
+% \setlength{\aftercolumseparator}{length}
+% \end{verbatim}
+% If you want to revert to the previous behavior, just set with a negative value. 
+% \DescribeMacro{\widthliketwocolumns}
+% If you want to mix two-column with single-column text, you can align horizontally single-column text to two-column text with \cs{widthliketwocolumnstrue}. To reset this feature, use \cs{widthliketwocolumnsfalse}.
+% You can also call \cs{widthliketwocolumns} as a global option when loading \Lpack{eledmac} or \Lpack{eledpar}
+% 
+% \DescribeMacro{\Xnoteswidthliketwocolumns}
+% \DescribeMacro{\notesXwidthliketwocolumns}
+% In most cases, you should use \cs{widthliketwocolumns} in combination with \cs{Xnoteswidthliketwocolumns} and \cs{notesXwidthliketwocolumns} to align the critical/familiar footnotes with the two colums. 
+% See \Lpack{eledmac}'s handbook for more details.
+% \section{Facing pages}\label{pages}
+% \subsection{Basic usage}
+% \DescribeEnv{pages}
+% Numbered text that is to be set on facing pages must be within a \verb?pages?
+% environment. Within the environment the text for the lefthand and righthand
+% pages is placed within the \verb?Leftside? and \verb?Rightside? 
+% environments, respectively.
+%
+% \DescribeMacro{\Pages}
+% The command \cs{Pages} typesets the texts in the previous pair of
+% \verb?Leftside? and \verb?Rightside? environments. 
+% The general scheme for parallel pages looks like this:
+% \begin{verbatim}
+% \begin{pages}
+% \begin{Leftside} ... \end{Leftside}
+% \begin{Rightside} ... \end{Rightside}
+% \begin{Leftside} ... \end{Leftside}
+% ...
+% \end{pages}
+% \Pages
+% \end{verbatim}
+% The \verb?Leftside? text is set on lefthand (even numbered) pages and
+% the \verb?Rightside? text is set on righthand (odd numbered) pages.
+% Each \cs{Pages} command starts a new even numbered page. After parallel
+% typesetting is finished, a new page is started.
+% Note that the \cs{Pages} \textbf{must be} outside of the \verb+pages+ environment.
+% \subsection{Text width}
+% \DescribeMacro{\Lcolwidth}
+% \DescribeMacro{\Rcolwidth}
+% Within the \verb?pages? environment the lengths \cs{Lcolwidth} and 
+% \cs{Rcolwidth} are the widths of the left
+% and right pages, respectively. By default, these are set to the normal
+% textwidth for the document, but can be changed within the environment if
+% necessary.
+% \subsection{Page number}
+% \changes{v1.15.0}{2015/05/18}{Add sameparallelpagenumber option.}
+% By default, \cs{Pages} use the standard \LaTeX\ page number scheme.
+% This means that pages are numbered continuously following printed-book conventions: from left-hand to right-hand side, left-hand pages having even numbers, right-hand pages having odd numbers.
+% 
+% \DescribeMacro{\sameparallelpagenumbertrue}\DescribeMacro{\sameparallelpagenumbertrue}However, you can use the package option \verb+sameparallelpagenumber+ to have the same page number for both left and right side.
+% In this case, this setting will apply only for pages typeset by \cs{Pages}, not for ``normal'' pages.
+% 
+% You can also switch the two system using \cs{sameparallelpagenumbertrue} and \cs{sameparallelpagenumberfalse}.
+%
+% \subsection{Setting the page breaking} 
+% \DescribeMacro{\goalfraction}
+% When doing parallel pages \Eledpar{} has to guess where TeX is going to 
+% put pagebreaks and hopefully get there first in order to put the pair of
+% texts on their proper pages. When it thinks that the fraction 
+% \cs{goalfraction} of a page has been filled, it finishes that page and 
+% starts on the other side's text. The definition is: \\
+% \verb?\newcommand*{\goalfraction}{0.9}? \\
+% If you think you can get more on a page, increase this. On the other hand,
+% if some left text overflows onto an odd numbered page or some right text
+% onto an even page, try reducing it, for instance by: \\
+% \verb?\renewcommand*{\goalfraction}{0.8}?
+% \subsection{Critical and familiar footnotes}
+% Of course, in ``Facing pages'',  the \Lpack{eledmac} both critical and familiar footnotes can be used.
+% However, some specific points must  be taken into consideration.
+% \subsubsection{Note size setting}
+% Since \Lpack{eledpar} v.1.13.0, long notes in facing pages can flow from left to right pages, and \emph{vice-versa}.
+% However, the \Lpack{eledmac} default setting for the maximum alloted size to notes is  greater than \cs{textheight}. That makes impossible for long notes to flow across pages.
+% \footnote{The same applies to \LaTeX\ normal notes. Read \url{http://tex.stackexchange.com/a/228283/7712} for technical informations.}
+% We have not changed this default setting, because we don't want to break compatibility with older version of \Lpack{eledmac}. 
+% So, you MUST change the default setting via \cs{maxhXnotes} (for critical notes)\cs{maxhnotesX} (for familiar notes). 
+% Both commands are explained in \Lpack handbook (\reff{eledmac-maxhXnotes}).
+% As an advisable setting:
+% \begin{verbatim}
+% \maxhXnotes{0.6\textheight}
+% \maxhnotesX{0.6\textheight}
+% \end{verbatim}
+% \subsubsection{Notes for one side only}
+% \DescribeMacro{\onlyXside}
+% \DescribeMacro{\onlysideX}
+% You may want to typeset notes on one side only (either left or right).
+% Use \cs{onlyXside}\oarg{s}\marg{p} to set critical notes, and \cs{onlysideX}\oarg{s}\marg{p} to set familiar notes.
+% \marg{p} must be set to \verb+L+ for notes to be confined only on the left side and to \verb+R+ for  notes to be confined only on the right side.
+% \subsubsection{Familiar notes called in the right side, but to be printed in the left side}
+% \DescribeMacro{\footnoteXnomk}
+% \DescribeMacro{\footnoteXmk}
+% As often happens, the left side has less room for text.
+% We may want to call familiar notes in the right side while using at the same time the available space in the left side to print them.
+%
+% To achieve this, we call \cs{footnoteXnomk}\marg{notecontent} in the left side. X is to be replaced by the series letter. We do this call in the left side after the word which matches up to the one in the right side after which we want to insert the actual footnote mark.
+%
+% In the right side, we call \cs{footnoteXmk} at the place we want to have the footnote mark. X is to be replaced by the series letter.
+% For example:
+% \begin{verbatim}
+%   \begin{Leftside}
+%    \beginnumbering
+%     \pstart 
+%      A little cat\footnoteAnomk{A note.}. And so one ...
+%     \pend
+%    \endnumbering
+%   \end{Leftside}
+%   \begin{Rightside}
+%    \beginnumbering
+%     \pstart 
+%      Un petit chat\footnotemk. And so one ...
+%     \pend
+%    \endnumbering
+%   \end{Rightside}
+% \end{verbatim}
+% \section{Left and right texts}\label{leftright}
+% \subsection{Environments}
+% Parallel texts are divided into Leftside and Rightside. The form of the
+% contents of these two are independent of whether they will be set 
+% in columns or pages.
+%
+% \DescribeEnv{Leftside}
+% \DescribeEnv{Rightside}
+% The left text is put within the \verb?Leftside? environment and the 
+% right text likewise in the \verb?Rightside? environment. The number of 
+% \verb?Leftside? and \verb?Rightside? environments must be the same.
+% \subsection{Line numbering scheme}
+% Within these environments you can designate the line numbering scheme(s)
+% to be used. 
+% \DescribeMacro{\firstlinenum}
+% \DescribeMacro{\linenumincrement}
+% \DescribeMacro{\firstsublinenum}
+% \DescribeMacro{\sublinenumincrement}
+% \DescribeMacro{\firstlinenum*}
+% \DescribeMacro{\linenumincrement*}
+% \DescribeMacro{\firstsublinenum*}
+% \DescribeMacro{\sublinenumincrement*}
+% The \Eledmac{} package originally used counters for specifying the 
+% numbering scheme; now both \Eledmac and
+% the \Eledpar{} package use macros instead. Following 
+% \cs{firstlinenum}\marg{num} the first line number will be \meta{num}, and
+% following \cs{linenumincrement}\marg{num} only every \meta{num}th
+% line will have a printed number. Using these macros inside the
+% \verb?Leftside? and \verb?Rightside? environments gives you independent 
+% control over the left and right numbering schemes. The \cs{firstsublinenum}
+% and \cs{sublinenumincrement} macros correspondingly set the numbering
+% scheme for sublines.
+% The starred versions change both left and right numbering schemes.
+%
+% Generally speaking, controls like \cs{firstlinenum} or \cs{linenummargin}
+% apply to sequential and left texts. 
+% To effect right texts only, they have 
+% to be within a \verb?Rightside? environment. 
+% \DescribeMacro{\lineationR}
+% \cs{lineationR} macro is the equivalent of \Lpack{eledmac} \cs{lineation} macro for the right side.
+% \DescribeMacro{\lineation*} 
+% \cs{lineation*} macro is the equivalent of \Lpack{eledmac} \cs{lineation} macro for both sides.
+% \subsection{chunk}
+% \DescribeMacro{\pstart}
+% \DescribeMacro{\pend}
+% In a serial (non-parallel) mode, each numbered paragraph, or chunk, 
+% is contained
+% between the \cs{pstart} and \cs{pend} macros, and the paragraph is output
+% when the \cs{pend} macro occurs. The situation is somewhat different
+% with parallel typesetting as the left text (contained within \cs{pstart}
+% and \cs{pend} groups within the \verb?Leftside? environment) has to be
+% set in parallel with the right text (contained within its own \cs{pstart}
+% and \cs{pend} groups within the corresponding \verb?Rightside? environment)
+% the \cs{pend} macros cannot immediately initiate any typesetting ---
+% this has to be controlled by the \cs{Columns} or \cs{Pages} macros.
+% Several chunks may be specified within a \verb?Leftside? or 
+% \verb?Rightside? environment.
+% A multi-chunk text then looks like:
+% \begin{verbatim}
+% \begin{...side}
+%   % \beginnumbering
+%   \pstart first chunk \pend
+%   \pstart  second chunk \pend
+%   ...
+%   \pstart  last chunk \pend
+%   % \endnumbering
+% \end{...side}
+% \end{verbatim}
+% Numbering, via \cs{beginnumbering} and \cs{endnumbering}, may extend
+% across several \verb?Leftside? or \verb?Rightside? environments. 
+% Remember, though,
+% that the left/right sides are effectively independent of each other.
+%
+% \subsection{\cs{AtEveryPstart} and \cs{AtEveryPstartCall}}
+% In general, remember that the moment where a \cs{pstart} is called is different 
+% from the moment when  the \cs{pstart}\ldots\cs{pend} content is printed, which is when \cs{Pages} or \cs{Columns} is processed.
+% 
+% Consequently:
+% \begin{itemize}
+%  \item The argument of \cs{AtEveryPstart} (see \reff{eledmac-AtEveryPstart}) is called before every chunk is printed, except if you used an optional argument for the \cs{pstart}.
+%  \item The argument of \cs{AtEveryPstartCall} is called before every \cs{pstart}.
+% \end{itemize}
+% \subsection{Language setting}
+% If you are using the 
+% \Lpack{babel} package with different languages 
+% (via, say, \cs{selectlanguage}) for the left and right texts it is 
+% particularly important to select the appropriate language within the
+% \verb?Leftside? and \verb?Rightside? environments. The initial language
+% selected for the right text is the \Lpack{babel} package's default. Also,
+% it is the \emph{last} \cs{selectlanguage} in a side that controls the
+% language used in any notes for that side when they get printed. If
+% you are using multilingual notes then it is probably safest to explicitly
+% specify the language(s) for each note rather than relying on the language
+% selection for the side. The right side language is also
+% applied to the right side line numbers.
+%
+% \subsection{Shifting}
+% Corresponding left and right sides must have the same number of
+% paragraph chunks --- if there are four on the left there must be four
+% on the right, even if some are empty. The start of each pair of left and
+% right chunks are aligned horizontally on the page. The ends may
+% come at different positions --- if one chunk is shorter than the other
+% then blank lines are output on the shorter side until the end of the longer
+% chunk is reached. 
+%
+% However, sometime if the left pstarts are much greater than right pstarts,
+% or \emph{vice-versa},
+% you can decide to shift the pstarts on the left and right side.
+% That means the start of pstarts are not aligned horizontally on the page,
+% the shift is offset at the end of each double pages.
+% To enable this function, load eledpar with the option \verb+shiftedpstarts+.
+% \section{Numbering text lines and paragraphs}
+%
+% \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} \\
+% These have to be separately specified within \verb?Leftside? and
+% \verb?Rightside? environments.
+%
+% 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. 
+% Separate auxiliary files are maintained for right hand texts and
+% these are named \meta{jobname}.\file{nnR}, using the `R' to distinguish
+% them from the left hand and serial (non-parallel) texts.
+%
+% \DescribeMacro{\memorydump}
+% The command \cs{memorydump} effectively performs an \cs{endumbering}
+% immediately followed by a \cs{beginnumbering} while not restarting the
+% numbering sequence. This has the effect of clearing TeX's memory of previous
+% texts and any associated notes, allowing
+% longer apparent streams of parallel texts. The command should be applied
+% to both left and right texts, and after making sure that all previous
+% notes have been output. For example, along the lines of:
+% \begin{verbatim}
+% \begin{pages}
+% \begin{Leftside}
+%   \beginnumbering
+%   ...
+% \end{Leftside}
+% \begin{Rightside}
+%   \beginnumbering
+%   ...
+% \end{Rightside}
+% \end{pages}
+% \Pages
+% \begin{pages}
+% \begin{Leftside}
+%   \memorydump
+%   ...
+% \end{Leftside}
+% \begin{Rightside}
+%   \memorydump
+%   ...
+% \end{pages}
+% \end{verbatim}
+% \DescribeMacro{\Rlineflag}
+% The value of \cs{Rlineflag} is appended to the line numbers of the
+% right texts. Its default definition is: \\
+% \verb?\newcommand*{\Rlineflag}{R}? \\
+% This may be useful for parallel columns but for parallel pages it might
+% be more appropriate to redefine it as: \\
+% \verb?\renewcommand*{\Rlineflag}{}?.
+% \DescribeMacro{\printlinesR}
+% \DescribeMacro{\ledsavedprintlines}
+% The \cs{printlines} macro is ordinarily used to print the line number 
+% references for critical footnotes. For footnotes from right side texts 
+% a special version is supplied, called \cs{printlinesR}, which incorporates
+% \cs{Rlineflag}. (The macro \cs{ledsavedprintlines} is a copy of the original
+% \cs{printlines}, just in case \ldots). As provided, the package makes no
+% use of \cs{printlinesR} but you may find it useful. For example, if you only
+% use the B footnote series in righthand texts then you may wish to flag
+% any line numbers in those footnotes with the value of \cs{Rlineflag}. You
+% could do this by putting the following code in your preamble:
+% \begin{verbatim}
+% \let\oldBfootfmt\Bfootfmt
+% \renewcommand{\Bfootfmt}[3]{%
+%   \let\printlines\printlinesR
+%   \oldBfootfmt{#1}{#2}{#3}}
+% \end{verbatim}
+% 
+%
+%
+%\changes{v0.9.0}{2011/10/01}{Possibility to number \cs{pstart}.}
+% It's 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 numerotation with \DescribeMacro{\numberpstartfalse}\cs{numberpstartfalse}. You can redefine the commands \DescribeMacro{\thepstartL}\cs{thepstartL} and \DescribeMacro{\thepstartR}\cs{thepstartR} to change style. The numbering restarts on each \cs{beginnumbering}
+% \section{Verse}
+%
+% If you are typesetting verse with \Eledmac{} you can use the \cs{stanza}
+% construct, and you can also use this in right or left parallel texts.
+% In this case each verse line is a chunk which has two implications.
+% (1) you can unexpectedly exceed the \cs{maxchunks} limit or the overall
+% limit on the number of boxes, and (2) left and right verse lines are
+% matched, which may not be desirable if one side requires more print lines
+% for verse lines than the other does.
+%
+% \DescribeEnv{astanza}
+% \Eledpar{} provides an \verb?astanza? environment which you can use instead
+% of \cs{stanza} (simply replace \verb?\stanza? by \verb?\begin{astanza}? and
+% add \verb?\end{astanza}? after the ending \verb?\&?). Within the 
+% \verb?astanza? environment each verse line is treated as a paragraph, 
+% so there must be no blank lines in the environment otherwise there will
+% be some extraneous vertical spacing.
+%
+%    If you get an error message along the lines of `Missing number, 
+% treated as zero \cs{sza@0@}' it is because you have forgotten to use
+% \cs{setstanzaindents} to set the stanza indents.
+%
+% \DescribeMacro{\skipnumbering}
+% The command \cs{skipnumbering} when inserted in a line of parallel text
+% causes the numbering of that particular line to be skipped. This can
+% useful if you are putting some kind of marker (even if it is only a 
+% blank line) between stanzas. Remember, parallel texts must be numbered
+% and this provides a way to slip in an `unnumbered' line.
+%
+%    The \verb?astanza? environment forms a chunk but you may want to
+% have more than one stanza within the chunk. Here are a couple of ways of 
+% doing that with a blank line between each internal stanza, and with
+% each stanza numbered. First some preliminary definitions:
+% \begin{verbatim}
+% \newcommand*{\stanzanum}[2][\stanzaindentbase]{%
+%   \hskip -#1\llap{\textbf{#2}}\hskip #1\ignorespaces}
+% \newcommand{\interstanza}{\par\mbox{}\skipnumbering}
+% \end{verbatim}
+% And now for two stanzas in one. In this first example the line numbering
+% repeats for each stanza.
+% \begin{verbatim}
+% \setstanzaindents{1,0,1,0,1,0,1,0,1,0,1}
+% \begin{pairs}
+% \begin{Leftside}
+%   \firstlinenum{2}
+%   \linenumincrement{1}
+%   \beginnumbering
+%   \begin{astanza}
+%     \stanzanum{1} First in first stanza &
+%                   Second in first stanza &
+%                   Second in first stanza &
+%                   Third in first stanza &
+%                   Fourth in first stanza &
+%     \interstanza
+%     \setline{2}\stanzanum{2} First in second stanza &
+%                   Second in second stanza &
+%                   Second in second stanza &
+%                   Third in second stanza &
+%                   Fourth in second stanza \&
+%   \end{astanza}
+%   ...
+% \end{verbatim}
+% And here is a slightly different way of doing the same thing, but with
+% the line numbering being continuous.
+% \begin{verbatim}
+% \setstanzaindents{1,0,1,0,1,0,0,1,0,1,0,1}
+% \begin{pairs}
+% \begin{Leftside}
+%   \firstlinenum{2}
+%   \linenumincrement{1}
+%   \beginnumbering
+%   \begin{astanza}
+%     \stanzanum{1} First in first stanza &
+%                   Second in first stanza &
+%                   Second in first stanza &
+%                   Third in first stanza &
+%                   Fourth in first stanza &
+%     \strut &
+%     \stanzanum{2}\advanceline{-1} First in second stanza &
+%                   Second in second stanza &
+%                   Second in second stanza &
+%                   Third in second stanza &
+%                   Fourth in second stanza \&
+%   \end{astanza}
+%   ...
+% \end{verbatim}
+%
+%
+%
+% \DescribeMacro{\hangingsymbol}Like in eledmac, you could redefine the command \cmd{\hangingsymbol} to insert a character in each hanging line. If you use it, you must run \LaTeX\ two time. Example for the French typography
+%\begin{verbatim}
+%\renewcommand{\hangingsymbol}{[\,}
+%\end{verbatim}
+%  You can also use it to force hanging verse to be flush right:
+% \begin{verbatim}
+% \renewcommand{\hangingsymbol}{\protect\hfill}
+% \end{verbatim}
+%
+%
+% When you use \cs{lednopb} make sure to use it on both sides in the corresponding
+% verses to keep the pages in sync.
+% \section{Side notes}
+% As in \Lpack{eledmac}, you must use one of the following commands to add side notes: \cs{ledsidenote}, \cs{ledleftnote}, \cs{ledrightnote}, \cs{ledouterote}, \cs{ledinnerrote}.
+% 
+% The \cs{sidenotemargin} defines the margin of the sidenote for either left or right side, depending on the current environment.
+% You can use \cs{sidenotemargin*} to define it for both sides.
+% \section{Parallel ledgroups}
+% \changes{v1.6.0}{2013/12/13}{Add tool and documentation for parallel ledgroups}
+% You can also make parallel ledgroups (see the documentation of eledmac about ledgroups).
+% To do it you have:
+% \begin{itemize}
+%   \item To load \Lpack{eledpar} package with the \verb+parledgroup+ option, or to add \cs{parledgrouptrue}.
+%   \item To push each ledgroup between \cs{pstart}…\cs{pend} command. 
+% \end{itemize} 
+% See the following example:
+% \begin{verbatim}
+%   \begin{pages}
+%    \begin{Leftside}
+%      \beginnumbering
+%      \pstart
+%        \begin{ledgroup}
+%          ledgroup content
+%        \end{ledgroup}
+%      \pend
+%      \pstart
+%        \begin{ledgroup}
+%          ledgroup content
+%        \end{ledgroup}
+%      \pend
+%      \endnumbering
+%    \end{Leftside}
+%    \begin{Rightside}
+%      \beginnumbering
+%      \pstart
+%        \begin{ledgroup}
+%          ledgroup content
+%        \end{ledgroup}
+%      \pend
+%      \pstart
+%        \begin{ledgroup}
+%          ledgroup content
+%        \end{ledgroup}
+%      \pend
+%      \endnumbering
+%    \end{Rightside}
+%   \end{pages}
+%   \Pages
+% \end{verbatim}
+% You can add sectioning a sectioning command, following this scheme:
+% \begin{verbatim}
+% \begin{..side}
+%      \beginnumbering
+%     \pstart
+%       \section{First ledgroup title}
+%     \pend
+%      \pstart
+%        \begin{ledgroup}\skipnumbering
+%           ledgroup content
+%        \end{ledgroup}
+%      \pend
+%     \pstart
+%     \section{Second ledgroup title}
+%     \pend
+%      \pstart
+%        \begin{ledgroup}\skipnumbering
+%           ledgroup content
+%        \end{ledgroup}
+%      \pend
+%      \endnumbering
+% \end{..side}
+% \end{verbatim}
+% \subsection{Parallel ledgroups and \Lpack{setspace} package}
+% If you use the \Lpack{setspace} package and want your notes in parallel ledgroups to be single-spaced (not half-spaced or double-spaced), just add to your preamble:
+% \begin{verbatim}
+% \let\parledgroupnotespacing\singlespacing
+% \end{verbatim}
+% \emph{In effect, to have correct spacing, don't change the font size of your notes}.

+% The standard sectioning commands of eledmac are available, and provide parallel sectionings, for both two-column and two-page layout.
+% \DescribeMacro{\eledsectnotoc}
+% By default, the section commands of the right side are not added to the table of contents.
+% But you can change it, using \cs{eledsectnotoc}\marg{arg}, where \meta{arg} could be \verb+L+ (for left side) or \verb+R+ (for right side).
+%
+% \DescribeMacro{\eledsectmark}
+% By default, the \LaTeX\ marks for header are token from left side. You can change it, using \cs{eledsectmark}\marg{arg}, where \meta{arg} could be \verb+L+ (for left side) or \verb+R+ (for right side).
+% \section{Implementation overview}\label{overview}
+%
+%    TeX is designed to process a single stream of text, which may include
+% footnotes, tables, and so on. It just keeps converting its input into
+% a stream typeset pages. It was not designed for typesetting two texts
+% in parallel, where it has to alternate from one to the other. Further,
+% TeX essentially processes its input one paragraph at a time --- it is
+% very difficult to get at the `internals' of a paragraph such as the
+% individual lines in case you want to number them or put some mark at the
+% start or end of the lines.
+%
+%    \Eledmac{} solves the problem of line numbering by putting the paragraph
+% in typeset form into a box, and then extracting the lines one by one 
+% from the box for TeX to put them onto the page with the appropriate page
+% breaks. Most of the \Eledmac{} code is concerned with handling this box
+% and its contents.
+%
+%    \Eledpar's solution to the problem of parallel texts is to put the two
+% texts into separate boxes, and then appropriately extract the pairs of
+% lines from the boxes. This involves duplicating 
+% much of the original box code for an extra right text box. The other, 
+% smaller,
+% part of the code is concerned with coordinating the line extractions from
+% the boxes.
+%
+%    The package code is presented in roughly in the same order as in \Eledmac.
+%

+% Announce the name and version of the package, which is 
+% targetted for LaTeX2e. The package also requires the \Eledmac{}
+% package.

+%    \end{macrocode}
+%  With the option `shiftedpstarts' a long pstart one the left side (or in the right side) doesn't make a blank on the corresponding pstart, but the blank is put on the bottom of the page. Consequently, the pstarts on the parallel pages are shifted, but the shift stops at every end of pages.
+% The \cs{shiftedverses} is kept for backward compatibility.

+%  As noted above, much of the code is a duplication of the original
+% \Eledmac{} code to handle the extra box(es) for the right hand side text,
+% and sometimes for the left hand side as well. In order to distinguish
+% we use `R' or `L' in the names of macros for the right and left code.
+% The specifics of `L' and `R' are normally hidden from the user by
+% letting the \verb?Leftside? and \verb?Rightside? environments set things
+% up appropriately.

+% \subsection{Line-number counters and lists}
+% \subsubsection{Correspond to those in \Lpack{eledmac} for regular or left text}
+% We need another set of counters and lists for the right text, 
+% corresponding to those in \Lpack{eledmac} for regular or left text.
+%
+% \begin{macro}{\line@numR}
+% \begin{macro}{\subline@numR}
+% \begin{macro}{\absline@numR}
+% The count \cs{line@numR} stores the line number that's used in
+% the right text's marginal line numbering and in notes. 
+% The count \cs{subline@numR} stores
+% a sub-line number that qualifies \cs{line@numR}. 
+% The count \cs{absline@numR} stores the
+% absolute number of lines since the start
+% of the right text section: that is, the number we've actually printed, 
+% no matter what numbers we attached to them. 
+%
+%    \begin{macrocode}
+\newcount\line@numR
+\newcount\subline@numR
+\newcount\absline@numR
+
+%    \end{macrocode}

+% \end{macro}
+%
+% \begin{macro}{\line@listR}
+% \begin{macro}{\insertlines@listR}
+% \begin{macro}{\actionlines@listR}
+% \begin{macro}{\actions@listR}
+% Now we can define the list macros that will be created from the
+% line-list file.  They are directly analagous to the left text ones.
+% The full list of action codes and their meanings is given in the \Eledmac{}
+% manual.
+%
+% Here are the commands to create these lists:
+%
+%    \begin{macrocode}
+\list@create{\line@listR}
+\list@create{\insertlines@listR}
+\list@create{\actionlines@listR}
+\list@create{\actions@listR}
+
+%    \end{macrocode}
+% \end{macro}

+% \subsubsection{Specific to \Lpack{eledpar}}
+% \begin{macro}{\linesinpar@listL}
+% \begin{macro}{\linesinpar@listR}
+% \begin{macro}{\maxlinesinpar@list}
+% In order to synchonise left and right chunks in parallel processing
+% we need to know how many lines are in each left and right text chunk,
+% and the maximum of these for each pair of chunks.
+%    \begin{macrocode}
+\list@create{\linesinpar@listL}
+\list@create{\linesinpar@listR}
+\list@create{\maxlinesinpar@list}

+%    \end{macrocode}

+% \end{macro}
+%
+%
+%
+% \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}
+\renewcommand*{\read@linelist}[1]{%
+%    \end{macrocode}
+% We do do different things depending whether or not we are processing 
+% right text
+%    \begin{macrocode}
+  \ifledRcol
+    \list@clear{\line@listR}%
+    \list@clear{\insertlines@listR}%
+    \list@clear{\actionlines@listR}%
+    \list@clear{\actions@listR}%
+    \list@clear{\linesinpar@listR}%
+    \list@clear{\linesonpage@listR}
+  \else
+    \list@clearing@reg
+    \list@clear{\linesinpar@listL}%
+    \list@clear{\linesonpage@listL}%
+  \fi
+%    \end{macrocode}
+%
+% Make sure that the \cs{maxlinesinpar@list} is empty (otherwise things
+% will be thrown out of kilter if there is any old stuff still hanging
+% in there).
+%    \begin{macrocode}
+  \list@clear{\maxlinesinpar@list}
+%    \end{macrocode}
+% Now get the file and interpret it.
+%    \begin{macrocode}
+  \get@linelistfile{#1}%
+  \endgroup
+%    \end{macrocode}
+%
+% When the reading is done, we're all through with the
+% line-list file. All the information we needed
+% from it will now be encoded in our list macros.
+% Finally, we
+% initialize the \cs{next@actionline} and \cs{next@action} macros,
+% which specify where and what the next action to be taken is.
+%    \begin{macrocode}
+  \ifledRcol
+    \global\page@numR=\m@ne
+    \ifx\actionlines@listR\empty
+      \gdef\next@actionlineR{1000000}%
+    \else
+      \gl@p\actionlines@listR\to\next@actionlineR
+      \gl@p\actions@listR\to\next@actionR
+    \fi
+  \else
+    \global\page@num=\m@ne

+      \gl@p\actions@list\to\next@action
+    \fi
+  \fi}
+
+%    \end{macrocode}
+% \end{macro}
+%
+% This version of \cs{read@linelist} creates list macros
+% containing data for the entire section, so they could get rather
+% large. The \cs{memorydump} macro is available if you run into
+% macro memory limitations.
+%
+% \subsection{Commands within the line-list file}
+%
+% This section defines the commands that can appear within a
+% line-list file, except for \cs{@lab} which is in a
+% later section among the cross-referencing commands it is
+% associated with.
+%
+% The macros with \verb"action" in their names contain all the code
+% that modifies the action-code list.
+% \begin{macro}{\@nl@regR}

+%
+% The \cs{edtext} (or \cs{critext}) macro is used to create all

+% 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.
+%
+% \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

+% \subsection{Specific hooks and commands for notes}
+% The \Lpack{eledmac} \cs{newseries@}  initalizes commands which are linked to notes series. 
+% However, to keep \Lpack{eledmac}  as light as possible, it does not define commands which are specific to \Lpack{eledpar}.
+% This is what does \cs{newseries@eledpar}. The specific hooks are also defined here.
+% \begin{macro}{\newseries@eledpar}
+%    \begin{macrocode}
+\newcommand{\newseries@eledpar}[1]{%
+%    \end{macrocode}
+% \subsubsection{Notes to be printed on one side only}
+% \Lpack{eledpar} allows notes to be printed on one side only.
+% We need to declare these options.
+% We also need boolean flags, and to set them to true when a note series is not printed on one side.
+% We check the \verb+nofamiliar+ and \verb+nocritical+ \Eledmac{} options.
+% \changes{v1.16.0}{2015/05/18}{Fix bug with \cs{onlysideX}.}

+      \csgdef{onlyXside@#1}{}%
+    \fi%
+%    \end{macrocode}
+% \subsubsection{Familiar footnotes without marks}
+% The \cs{footnoteXnomk} commands are for notes which are printed on the left side, while they are called in the right side.
+% Basically, they set first toggle \cs{nomark@} to true, then call the \cs{footnoteX}.
+% and finally add the footnote counter in the footnote counter list.
+%
+% First, check the \verb+nofamiliar+ option of \Eledmac{}
+%    \begin{macrocode}
+  \unless\ifnofamiliar@%
+% So declare the list.
+%    \begin{macrocode}
+      \expandafter\list@create\csname footnote#1@mk\endcsname%
+%    \end{macrocode}
+% Then, declare the \cs{footnoteXnomk} command.
+%    \begin{macrocode}
+      \expandafter\newcommand\csname footnote#1nomk\endcsname[1]{%
+%    \end{macrocode}
+% First step: just call the normal \cs{footnoteX}, saying that we don't want to print the mark.
+%    \begin{macrocode}
+         \toggletrue{nomk@}%
+         \csuse{footnote#1}{##1}%
+         \togglefalse{nomk@}%
+%    \end{macrocode}
+% Second, and last, step: store the footnote counter in the footnote counters list.
+% We use some \cs{let}, because \cs{xright@appenditem} is difficult to use with \cs{expandafter}.
+%    \begin{macrocode}
+         \letcs{\@tmp}{footnote#1@mk}%
+         \numdef\@tmpa{\csuse{c@footnote#1}}%
+         \global\xright@appenditem{\@tmpa}\to\@tmp%
+         \global\cslet{footnote#1@mk}{\@tmp}%
+     }%
+%    \end{macrocode}
+% Then, declare the command which inserts the footnotemark in the right side.
+%    \begin{macrocode}
+      \expandafter\newcommand\csname footnote#1mk\endcsname{%
+%    \end{macrocode}
+% Get the first element of the footnote mark list.
+% As \cs{gl@p} is difficult to use with dynamic name macro, we use \cs{let} commands.
+%    \begin{macrocode}
+         \letcs{\@tmp}{footnote#1@mk}%
+         \gl@p\@tmp\to\@tmpa%
+         \global\cslet{footnote#1@mk}{\@tmp}%
+%    \end{macrocode}
+% Set the footnotecounter with it. 
+% For the sake of security, we make a backup of the previous value.
+%    \begin{macrocode}
+         \letcs{\old@footnote}{c@footnote#1}%
+         \setcounter{footnote#1}{\@tmpa}%
+%    \end{macrocode}
+% Define the footnote mark and print it
+%    \begin{macrocode}
+         \protected@csxdef{@thefnmark#1}{\csuse{thefootnote#1}}%
+         \csuse{@footnotemark#1}%
+%    \end{macrocode}
+% Restore previous footnote counter and finally add space.
+%    \begin{macrocode}
+         \setcounter{footnote#1}{\old@footnote}%
+         \xspace%
+      }%
+%    \end{macrocode}
+% End of tools for familiar notes without marks
+%    \begin{macrocode}
+  \fi
+%    \end{macrocode}
+% End of \cs{newseries@eledpar}.
+%    \begin{macrocode}
+}%
+%    \end{macrocode}
+% \end{macro}
+% \subsubsection{Create hooks}
+% Read the eledmac code handbook about \cs{newhookcommand@series}.
+% Here, we create hooks which are specific to \Lpack{eledpar}.
+%    \begin{macrocode}
+\unless\ifnocritical@%
+  \newhookcommand@series{onlyXside}%
+\fi%
+\unless\ifnofamiliar@%
+  \newhookcommand@series{onlysideX}%
+\fi
+
+
+%    \end{macrocode}
+% \subsubsection{Init standards series (A,B,C,D,E,Z)}
+% \begin{macro}{\init@series@eledpar}
+% \cs{newseries@eledpar} is called by \cs{newseries@}.
+% However, this command is called before \Lpack{eledpar} is loaded.
+% Thus, we need to initiate a specific series hook for eledpar.
+%    \begin{macrocode}
+\newcommand{\init@series@eledpar}{%
+  \def\do##1{\newseries@eledpar{##1}}%
+  \dolistloop{\@series}%
+}%
+\init@series@eledpar%
+%    \end{macrocode}
+% \end{macro}
+% \section{Pstart numbers dumping and restoration}
+% While in \Lpack{eledmac} the footnotes are inserted in the same time as the \cs{pstart} …\cs{pend} are read, in \Lpack{eledpar} they are inserted when the \cs{Columns} or \cs{Pages} commands are called.
+% Consequently, if we do nothing, the value of the PstartL and PstartR counters are not the same in the main text and in the notes.
+% To solve this problem, we dump the values in two list (one by side) when processing \cs{pstart} and restore these at each \cs{pstart} when calling \cs{Columns} or \cs{Pages}. 
+% We also dump and restore the value of the boolean \cs{ifnumberpstart}.
+
+% So, first step, creating the lists. 
+% Here, ``pc'' means ``public counters''.
+% \begin{macro}{\list@pstartL@pc}
+% \begin{macro}{\list@pstartR@pc}
+%    \begin{macrocode}
+\list@create{\list@pstartL@pc}%
+\list@create{\list@pstartR@pc}%
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% Two commands to dump current pstarts. 
+% We prefer two commands to one with argument indicating the side, 
+% because the commands are short, and so we save one test (or a \cs{csname} construction).
+% \begin{macro}{\dump@pstartL@pc} 
+% \begin{macro}{\dump@pstartR@pc}

+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\restore@pstartL@pc}

+% \section{Paragraph decomposition and reassembly}
+% \label{paragraph}\relax
+%
+% In order to be able to count the lines of text and affix line
+% numbers, we add an extra stage of processing for each paragraph.
+% We send the paragraph into a box
+% register, rather than straight onto the vertical list, and when
+% the paragraph ends we
+% slice the paragraph into its component lines; to each line we
+% add any notes or line numbers, add a command to write to the
+% line-list, and then at last send the line to the vertical list.
+% This section contains all the code for this processing.
+%
+% \subsection{Boxes, counters, {\tt\protect\bslash pstart}
+% and {\tt\protect\bslash pend}}
+%
+% \begin{macro}{\num@linesR}
+% \begin{macro}{\one@lineR}
+% \begin{macro}{\par@lineR}
+% Here are numbers and flags that are used internally in the course
+% of the paragraph decomposition.
+%
+% When we first form the paragraph, it goes into a box register,
+% \cs{l@dLcolrawbox} or \cs{l@dRcolrawbox} for right text, instead of onto the 
+% current vertical list.
+% The \cs{ifnumberedpar@} flag will be \verb"true" while a paragraph is
+% being processed in that way.
+% \cs{num@lines(R)} will store the number of lines in the paragraph
+% when it's complete. When we chop it up into lines, each line
+% in turn goes into the
+% \cs{one@line} or \cs{one@lineR} register, and \cs{par@line(R)} 
+% will be the number
+% of that line within the paragraph.

+% \cs{add@penaltiesL} is

+% of the appropriate size
+% back into the paragraph; these penalties get

+% \cs{brokenpenalty} are not restored, since we have no easy way to
+% find out where we should insert them.
+%
+% \phantomsection\label{add@penalties}
+% In the code below, which is a virtual copy of the original
+% \cs{add@penalties}, \cs{num@lines} is the number of lines in the whole
+% paragraph, and \cs{par@line} is the line we're working on at the
+% moment.  The count \cs{@l@dtempcnta} is used to calculate and
+% accumulate the penalty; it is initially set to the value of
+% \cs{ballast@count}, which has been worked out in \cs{do@ballast}.
+% Finally, the penalty is
+% checked to see that it doesn't go below $-10000$.

+% \changes{v1.13.1}{2015/03/12}{Correct \cs{correct@footinsX@box} and \cs{correct@Xfootins@box}}
+% \changes{v1.13.1}{2015/03/12}{Call \cs{correct@footinsX@box} and \cs{correct@Xfootins@box} directly in \cs{print@notesX@forpages} and \cs{print@Xnotes@forpages}.}
+% The \cs{onlyXside} and \cs{onlysideX} hooks for \cs{Pages}
+% allow notes to be printed  either in left or right pages only.
+% The implementation of such features is delegated to \cs{print@Xnotes@forpages},
+% which replaces \cs{print@Xnotes} inside \cs{Pages}. 
+% Here is how we proceed\footnote{See \url{http://tex.stackexchange.com/a/230332/7712}.}:
+% \begin{itemize}
+%    \item If notes are to be printed in both sides, we just proceed the usual way: print the foot starts for the series, then the foot group.
+%    \item If notes are to be printed in the left side, we do these prints only for even pages ; if notes are to be printed in the right side, we do these prints only for odd pages.
+%    \item However, that is not enough. Because the problem does not only consists in printing notes in any particular page. It is also not to put aside room for notes in the pages where we don't want to print them.
+%    To take an example: if some note in the left side is too long by 160pt to be printed in full in the left page, we do not want to put aside 160pt a space for it in the following right page. 
+%    \item To solve this problem, we change the magnification factor associated with notes before going to the next page.
+%    If we start a page where no notes are supposed to be  printed, the magnification counter is set to 0. We also set the note skip to 0pt. Before starting a new page where these notes are supposed to be printed, we reset these counter and skip to their default values. (About these counter and skip, read \texbook\ p.~122-125).
+%    \item There still remains a last problem. This problem is quite complex to understand, so an example will speak for itself. Suppose we allow 10 lines of notes by page.
+%    Suppose a long note, be it 25 lines, which needs three pages to be printed. Suppose it must be printed only on left pages, namely odd pages. 
+%
+%     On p.~2, the first 10 lines of the notes are printed.
+%     On p.~3, the box associated to the notes contains 10 lines. However, as we are in a right page, we don't void this box. So \TeX\ will keep its content for the pages to come. However, on p.~4 it will also add one line in the footnote box, because in any case, \TeX adds some content in the box when preparing the output routines, even if there is some content left in this box from the previous pages. 
+%     So the lines in the note box at p.~4 will be $10+1=11$. There is one line which should not be there. Furthermore, as the box size is for 10~lines and not for 11~lines, this last line will be glued to the previous one.
+% 
+%     To fix this double issue:
+%  \begin{itemize}
+%        \item For the pages where notes must be NOT printed, we allow to every note box one line less than it ought to be.
+%        In our example, that means that we allow \TeX\ to add only $10-1=9$ line in the note box on p.~3. 
+%        Before shifting to the pages where notes must be  printed, we allow to every notes the expected number of lines. In our example, that means that we allow \TeX to add 10~lines in the note box on p.~4. As on p.~3 only 9 lines were allowed, that means note box of p.~4 will contain $9+1=10$ lines. So the ``one line too many'' problem is solved.
+%        \item Still remains the ``glue'' problem. We solve it by recreating a clean note box. We split the one which is created by \TeX\ to get the next line printed. Then, we create the new box, by bringing together the first part and the last part of the splitted box, adding some skip between them. That is achieved by \cs{correct@Xfootins@box} (or \cs{correct@footinsX@box} for familiar notes).

+% \section{Fixing babel}

+%    With parallel texts there is the possibility that the two sides
+% might use different languages via \verb?babel?. On the other hand,
+% \verb?babel? might not be called at all (even though it might be already
+% built into the format).
+% \changes{v0.2.0}{2004/12/20}{Added section of babel related code}
+%
+%    With the normal sequential text each line is initially typeset
+% in the current language environment, and then it is output at which
+% time its attachments are typeset (in the same language environment.
+% In the parallel case lines are typeset in their current language but
+% an attachment might be typeset outside the language environment
+% of its line if the left and right side languages are different.
+% To counter this, we have to make sure that the correct language is
+% used at the proper times.

+% The \verb+sameparallelpagenumber+  allow to have the same page number for the left and the right side

+% As we are inside a group, the patch is local, and, consequently, the page printed after the \cs{Pages} will use the normal page number scheme.
+%
+% The value of \verb+sameparallelpage@number+ is increase by 1 when we change from right page to left page.

+% \subsection{Migration to eledpar 1.4.3}
+% Version 1.4.3 corrects a bug added in version 0.12, which made hanging verse automatically flush right, despite the given value of the first element of the \cs{setstanzaindents} command.
+% 
+% If, however, you want to return to automatic flush-right margins for verses with hanging indents, you have to redefine the \cs{hangingsymbol} command.
+% \begin{verbatim}
+%   \renewcommand{\hangingsymbol}{\protect\hfill}
+% \end{verbatim}
+% See the two following examples:
+%
+% With standard \cs{hangingsymbol}:
+% \setstanzaindents{4,0}
+% \beginnumbering
+%     \stanza
+%   A very long verse should be sometime hanged. 
+%  The position of the hanging verse is fixed.\&
+% \endnumbering
+%
+% With the modification of \cs{hangingsymbol}:
+% \renewcommand{\hangingsymbol}{\protect\hfill}
+% \setstanzaindents{4,0}
+% \beginnumbering
+%     \stanza
+%   A very long verse should sometimes be hanging. And we can see that an hanging verse is flush right.\&
