%  \textsf{edmargin} provides multiple endnotes sections with running
%  headers of the form ``Notes to pp.~xx--yy'' for critical editions.
%  Rather than having endnote marks in the text, \textsf{edmargin}
%  puts markers in the margins referring to the page in the endnotes
%  sections to which the note refers.

% \section{Introduction} \textsf{edmargin} provides a simple scheme
% for making critical editions.  All critical editions provide several
% series of notes, such as notes about emendations, explanatory notes,
% and notes about the text.  It is a common practice to tie these
% notes to line numbers in the text, whether typographical lines in
% prose text or verse lines in poetry.  Some editions of prose works
% enumerate sentences and paragraphs rather than lines, as the Bible
% does. All of these systems involve considerable amounts of 
% laborious markup.  \textsf{edmargin} provides a different system of 
% annotation which minimizes markup, and also minimizes the 
% possibilities of conflicts among commands. In the text, instead of 
% placing a marker, or remembering the line or sentence number, 
% \textsf{edmargin} simply places a mark in the margin (as for 
% instance ``c'' for a commentary, ``t'' for a textual note, or ``e'' 
% for an emendation) followed by the page number in the relevant 
% endnotes section to which the note refers. So, for instance, if on 
% page 42 of my text I have the anchor for an explanatory note which 
% appears on page 563 of the endnotes section for explanatory notes, 
% \textsf{edmargin} would put \emph{c: p.~563} in the margin on page 
% 42 of the line where that note occurs, and the text of the note 
% would appear on p.~563, with a reference to the page in the text to 
% which it occurs and a lemma drawn from that text. \textsf{edmargin} 
% comes with three built in categories of endnotes (emendations, 
% explanatory notes, textual notes), and facilities for easily 
% constructing other categories of endnote. All of the endnote 
% sections will have running headers of the form ``Textual Notes to 
% pp.~xx--yy.''
%
% This scheme for a critical edition, while considerably simpler than 
% the traditional schemes, does provide the information a critical 
% edition requires, and should be easy for readers to use, provided 
% that there are not many notes on every line. The scheme is modelled 
% on that used by David V. Erdman and Harold Bloom in their edition of 
% \emph{The Complete Poetry and Prose of William Blake}. \textsf{edmargin} 
% can also make notes with markers in the text, in the traditional 
% fashion.
%
%
% With the standard document classes, or the komascript classes,  
%  \textsf{edmargin} requires the following packages to work correctly:
% \textsf{fancyhdr},
% \textsf{ifthen} (for comparing page numbers), \textsf{needspace} (to
% prevent widowed chapter titles in notes sections when resetting
% notes by chapter using either |\notesbychapter| or
% |\resetendnotes|), and \textsf{titleref} (to send the chapter titles
% to the notes section). Because the marginal references are set with 
% |\marginpar| you should also call \textsf{mparhack} if you are 
% setting with the ``twoside'' option. \textsf{edmargin} sets very 
% narrow margin references (only 2em wide). If you are using 
% marginpars for any other purpose, you may need to adjust the width, 
% and monkey with the other parameters to make the marginal 
% references on both sides look symmetrical. To change the width of 
% the marginpars to 4em, issue |\setlength{\marginparwidth}{4em}|.
%
% With \textsf{memoir} class, \textsf{edmargin} requires fewer
% packages, since many of the package functions are built into
% \textsf{memoir} and some, \textsf{fancyhdr} most especially,
% conflict with it.  Minimally, you will need 
% \textsf{ifthen}.  You might wish to call \textsf{memoir} with the
% oldfontcommands option.
%
% \section{Setup} \DescribeMacro{\setupendnoteheaders}
% |\setupendnoteheaders| opens an external channel to receive each of the
% three preset kinds of endnote,  opening external
% files for emendations, textual collations, and explanatory notes
% (with extensions .emd, .ent, and .enx respectively).  Then it sets
% the first page of each notes section to the |empty| pagestyle, since
% you normally don't have running headers on the first page of a
% section.  And it changes the pagestyle for subsequent pages to have
% a running header of the form ``Notes to pages xx--yy.''  This text
% will appear in the center of each header.  It also writes
% information to the external file which will send information to the
% table of contents when the external file for the endnotes section is read back into your
% document.  Each note written to the file increments a counter that
% keeps track of all the endnotes (even if you are resetting the
% number by chapter).  \textsf{edmargin} creates two labels and two
% pagerefs for every note, a label and a pageref for each page in the
% main text \emph{from} which a note comes, and a label and a pageref
% for each page in the notes sections \emph{upon} which the note is
% written.  Finally \textsf{edmargin} writes on the external file for
% the endnotes a command to update the running header for that page of the
% endnotes to be sure that it correctly reflects the pages in the 
% main text from which the notes are drawn.
%
% \DescribeMacro{\makeemendations} \DescribeMacro{\maketextnotes}
% \DescribeMacro{\makeexplanatorynotes} You can use these commands
% individually to set up the predefined classes of endnote, rather
% than using |\setupendnoteheaders| to have \textsf{edmargin} put all three classes
% of  notes in the backmatter of your volume.  (This would be useful if you are not
% intending to make use of all three classes of note.)

% \DescribeMacro{\putemendations} \DescribeMacro{\puttextnotes}
% \DescribeMacro{\putexplanatory} |\puttextnotes|, |\putexplanatory|,
% or |\putemendation| read the external files back into your document
% at the place you specify. Remember that these commands change the
% page style, so if any sections that do not use the same type of running
% header follow these sections (the bibliography, 
% for instance), be sure to restore your prevailing headings style by 
% issuing, for example, |\pagestyle{headings}|
% |\thispagestyle{empty}|. 
%  
%
% \DescribeMacro{\notesbychapter} |\notesbychapter| 
%  resets  the note counters for each kind of endnote and 
% puts a centered line reading ``Chapter \textless\emph{chapter
% number}\textgreater ~ \textless\emph{chapter title}\textgreater'' in
% each of the three predefined sections of the the notes whenever
% |\chapter| is issued.  If you want only the chapter number, not its
% title, issue |\titleinnotesfalse| in your preamble.  Please note
% that with the standard classes \textsf{edmargin} modifies
% |\@chapter|, adding a few lines on to the end of the command.  If
% some other package does the same, you may need to reconcile them.
% With \textsf{memoir} class, |\chapter| is modified only if
% |\notesbychapter| is issued.
%
% \begin{sloppypar}
% \DescribeMacro{\setstyleforchapternotebegin} 
% \DescribeMacro{\setstyleforchapternoteend} 
% |\setstyleforchapternotebegin| and |\setstyleforchapternoteend| 
% allows you to customize the appearance of the line that separates 
% chapters in the endnotes. If, for instance, rather having a 
% centered line in the small font size, you want a flushleft line in 
% the large fontsize, issue 
% |\setstyleforchapternotebegin{\begin{flushleft}\large}| and 
% |\setstyleforchapternoteend{\end{flushleft}}| in your preamble.
% To set these lines in italic or bold, issue 
% |\setstyleforchapternotebegin{\em}| or 
% |\setstyleforchapternotebegin{\bf}| in your preamble. (It's safe, 
% indeed required, to use the old style font commands here, since the 
% chapter title line in the notes is confined to a group, which 
% restricts the scope of the font style command to the line.) If you are
% using \textsf{memoir} class, you should use the oldfontcommands option if you
% plan on issuing |\setstyleforchapternotebegin| and |\setstyleforchapternoteend|.
% Remember that if you open an environment with 
% |\setstyleforchapternotebegin| you must close it in 
% |\setstyleforchapternoteend|. So, for instance, if you wish the 
% chapter line to be set flushleft, in boldface, in normal font size, 
% you would issue 
% |\setstyleforchapternotebegin{\begin{flushleft}\begin{bf}\normalsize}| and 
% |\setstyleforchapternoteend{\end{bf}\end{flushleft}}| in your 
% preamble.
% \end{sloppypar}
%
% \DescribeMacro{\resetendnotes} Conceivably you might wish to do what
% |\notesbychapter| does for each chapter individually. Issue this 
% command just after theh |\chapter| command.  For instance,
% there may be a chapter without endnotes, in which case
% |\notesbychapter| would issue the centered line for that chapter,
% but no notes would follow, which is ugly.  Also, since the
% Bibliography is, as far as memoir class is concerned, a chapter, you
% must use |\resetendnotes| before each chapter rather issuing
% |\notesbychapter| in the preamble if you have a bibliography, or odd
% results will follow.  |\resetendnotes| will put a divider line (and
% give the chapter name) in the endnotes for all three of the preset
% endnote sections.  It will also put a divider line (and give the
% chapter name) for any section you add using |\definenewnotetype|, if
% you define new species of note types.  This is convenient if you
% know that there will be each species of note for a given chapter.
% If the chapter does not include one of the species of notes, you
% would be wiser to use the individual commands in the next paragraph
%
% \DescribeMacro{\resettextnotes} \DescribeMacro{\resetemendations}
% \DescribeMacro{\resetexplanatory} These commands do what
% |\resetendnotes| does, but only for the named section, not for all
% three predefined endnote sections.  If you used |\definenewnotetype|
% to create a new kind of endnote, you will also be able to use the
% corresponding ``reset'' command.  For instance, if you created an
% |\xyznote| command, you can issue |\resetxyznotes|.  If you use
% these commands, issue |\label{chapter\thechapter}| just after the
% |\chapter| command, and then issue the reset commands you plan to 
% use.
%
% \section{Predefined Endnote Sections}
% \textsf{edmargin} comes with three predefined endnotes sections and 
% three predefined kinds of endnote, |\textnote{}|, |\emendation{}|, 
% and |\explanatory{}|. 
%
%
% \DescribeMacro{\textnote} \DescribeMacro{\explanatory} 
% \DescribeMacro{\emendation} Use |\textnote| and its siblings as you 
% would use an ordinary |\endnote|. The argument of each note can be whatever you 
% wish, but for clarity it is a good idea to use as a lemma from the 
% text, since that will make the passage the note refers to clear. 
% For example: |\textnote{lemma] comment}|.
%
% \DescribeMacro{\literaltextnote} \DescribeMacro{\literalemendation} 
% \DescribeMacro{\literalexplanatory} |\literaltextnote| and its 
% siblings are useful for sending information directly to the 
% endnotes section to which the command refers. All of these commands 
% send unexpanded text to the endnote sections, so you use this command
% to send  to the endnote sections commands which will be executed when the endnote section is 
% read back into your document. You can send expanded text using 
% |\immediate\write\textnotes| and its siblings.
%
% \DescribeMacro{\notesincontents} If you do not wish to include a
% line for the endnotes in the table of contents, issue
% |\notesincontentsonfalse|. (This is the default).  To include a line
% for the endnotes in the table of contents, issue |\notesincontents|
% or (toggling the boolean) |\notesincontentsontrue|.  If you wish to
% rethink how to present the notes in the table of contents, rather than
% issuing |\notesincontents|  include
% an |\addtocontents| line in the main text just before you issue |\puttextnotes| or its siblings, the
% command which will read all of your endnotes into your document at
% that point.  For instance, |\notesincontents| sets the word ``Textual Notes'' in the
% table of contents flush with the left margin, just where the numbers
% in the preceding chapters are.  You might, however, wish to indent
% that word just a bit, so that it will be flush with the chapter
% titles above, rather than with the chapter numbers.  If you wish to
% do this, just before issuing |\puttextnotes|, issue
% |\addcontentsline{toc}{chapter}{\protect\numberline{}\the\textnotescontentsname}|.
% Use a similar line for the other endnotes sections, replacing |\textnotescontentsname|
% with |\emendationscontentsname| or |\explanationscontentsname| as the case may be.
%
% \section{Creating New Endnote Sections} 
% \DescribeMacro{\definenewnotetype} You can create as many new kinds 
% of endnote sections as you wish, using the |\definenewnotetype| 
% command. This macro will 
% \begin{enumerate}
% \item Open a new output stream and create a new external file to hold the 
% notes.
% \item Define a ``literalwrite'' command, on the model of 
% |\literaltextnote| for writing literal text directly to that external file.
% \item Send information to that file to set the page style and the 
% running header
% \item Send information to that file to set the title of the endnotes 
% section, and formatting information for the note text. 
% \item Sets up an entry for the table of contents for the note section
% \item Defines a new ``note'' command, and a new marginal marker for 
% that note
% \item Defines a new ``reset'' command for setting notes by chapter, 
% and modifies |\resetendnotes| and |\notesbychapter| to include that 
% new reset command when those two commands are issued
% \item Defines a new ``put'' command (on the model of 
% |\puttextnotes|) 
% for closing the external file and reading it into the text.
% \end{enumerate}
%
% This monster command takes \emph{six} arguments, which are used for 
% setting the names of the various files and commands it creates, and 
% for defining such things as the title of the new notes section and 
% the marginal mark it places in the main text. These arguments, in 
% order, specify
% \begin{enumerate}
% \item The base name used to construct all the commands.
% \item The extension used for the external file
% \item The section title in the running headers of the note section
% \item The section title at the beginning of the note section
% \item The name of the section in the table of contents section
% \item The marginal mark placed by the note command in the text
% \end{enumerate}
% 
% So, for instance,\begin{verbatim}
% \definenewnotetype{xyznote}{xyz}{Xyznotes to}{XYZNOTES}{Xyznotes}{x}
% \end{verbatim} creates a note command |\xyznote{}|, and a command
% for sending literal text to the new note section |\literalxyznote|,
% both of which write to an external file |\jobname.xyz|, sets running
% headers for the notes sections of the form ``Xyznotes to
% pp.~52-60,'' write a title line in the endnotes section giving the
% title as XYZNOTES, writes an entry in the table of contents for
% Xyznotes, and sets the marginal mark set by an |\xyznote| to be
% ``x''. You can read in the xyznotes section into your document with 
% the command |\putxyznote|. And |\resetendnotes| and 
% |\notesbychapter| will put chapter titles in the xyznotes section, 
% just as they do for the textual notes, the explanatory notes, and 
% the emendations sections. Finally, you can use |\resetxyznotes| to 
% set a chapter title in only the xyznotes section.
%
% A trivial use of this commmand would be to make traditional
% endnotes, in which case \textsf{edmargin} would merely be a
% replacement (with a slightly different command set) for
% \textsf{endnote} and \textsf{endheads}.  The command for doing this
% would be \begin{verbatim} \definenewnotetype{endnote}{enn}{Endnotes
% to}{ENDNOTES}{Endnotes}{\relax} \end{verbatim}
% 
% \section{Using \textsf{edmargin} in a Multilingual World}
% 
% By default, \textsf{edmargin} uses English language running 
% headers, but these are easily changed.
% 
% \begin{sloppypar} \DescribeMacro{\changetextnotesname} To change the
% title in the text for the endnote section for textual notes (the
% default is TEXTUAL NOTES), issue |\changetextnotesname{yourversion}|.  To change the running header (by default ``Textual Notes
% to'') issue |\changetextnotesheader{your version}|.  To change the
% name of the textual notes section in the table of contents (the
% default is ``Textual Notes'') issue |\changetextnotescontentsname.|
% Equivalent commands for emendations are |\changeemendationsname|
% |\changeemendationsheadername| and |\changeemendationscontentsname|.
% Equivalent commands for explanatory notes are
% |\changeexplanationsname| |\changeexplanationsheader| and
% |\changeexplanationscontentsname|.  \end{sloppypar}
%
%
% \begin{sloppypar}
% \DescribeMacro{\changesinglepageabbrev}
% \DescribeMacro{\changemultiplepageabbrev} Running headers refer to
% single pages with the English abbreviation ``p.''  and to multiple
% pages with the English abbreviation ``pp.''  To change these issue
% |\changesinglepageabbrev{new abbrev}| or
% |\changemultiplepageabbrev{new abbrev}| respectively.  The ultimate
% outcome is to translate a header of the form ``Notes to
% pp.~xx-yy'' to the form appropriate for your
% language. \end{sloppypar}
%
% \begin{sloppypar}
% \DescribeMacro{\changechapternotesline}If you are using |\resetendnotes| 
% or |\setnotesbychapter| you may also want to 
% change the text of the line those commands add to the endnotes so as to use some
% other word than ``Chapter.''  To change this, 
% issue |\changechapternotesline{your version}|.\end{sloppypar}
%
% \DescribeMacro{\backmattertextfont} |\edmargin| sets the endnote 
% text in the |\small| size. To change it to |\normalsize| issue
% |\renewcommand{\backmattertextfont}{\normalsize}|.
%
% \section{Customization} 
% \DescribeMacro{\notemarkinmargin} 
% \DescribeMacro{\notemarkintext}
% Rather than using marginal references, 
% \textsf{edmargin} can be set to put regular endnote markers in the 
% text and in the endnote sections. The different series of endnotes 
% will be distinguished by using the same abbrevations that were used 
% for marginal references. So, for 
% instance, the third textual note will have a mark that looks 
% ``t:3'' both in the text and in the textual notes section, and the 
% fifth explanatory note will have a mark that ``c:5'' both in the 
% text and in the textual notes section. You can put the endnote 
% markers in the main text rather than in the margins by issuing 
% |\notemarkintext| in your preamble. Putting the endnote 
% markers in the margin is the default, but you can make sure that 
% they go there by issuing |\notemarkinmargin|.
%
% \begin{sloppypar}
% \DescribeMacro{\textnotesparamode} 
% \DescribeMacro{\emendationsparamode} 
% \DescribeMacro{\explanationsparamode} If you wish to print your 
% endnotes as block paragraphs, rather than giving a paragraph to 
% each note, issue |\textnotesparamode|, |\emendationsparamode|, or 
% |\explanationsparamode|, as the case may require. If you have used 
% |\definenewnotetype| to define a note type called |\xyznote|, you 
% can set these notes in block paragraphs by issuing 
% |\xyznotesparamode|. You might consider setting your notes in block 
% paragraphs if you have very many very short notes. \end{sloppypar}
% 
% \section{Known Issues} Because the marginal references are set with 
% |\marginpar| some of them will appear on the wrong side in 
% two-sided printing, unless you include \textsf{mparhack} in your 
% list of packages. Also, if you have more than one reference on a 
% line, the second reference will be moved down a line (marginpars 
% are floats). This may not be an issue if the lemma in the second note 
% makes it clear what in the text it refers to. This problem can be 
% remedied by substituting the \textsf{marn} package and using the 
% |\marn| command in place of |\marginpar|.
%
% Using |\definenewnotetype| with |\notesbychapter| or 
% |\resetendnotes| causes a complaint that an |\iftrue| has been left 
% open whenever a |\chapter| command is written. The origin is 
% probably a problem with |\appendtomacro|. But the error is 
% harmless, it turns out, so I haven't tracked it down.

% \section{Implementation}
% \subsection{General Purpose Routines}
% Essentially these routines are code posted by Heiko Oberdiek to 
% comp.text.tex. If you set a counter from a |\pageref|, that 
% |\pageref| is undefined on the first run, and \TeX\ will not only 
% complain about the undefined reference, but give a ``missing 
% number'' error if you try to do anything with that reference, such 
% as compare one page number to another. These commands enable one to 
% use the |\pageref| without generating the missing number error on 
% the first run.

% expanded on the external files for the endnotes, |\jobname.ent| and
% its friends.  Everything except the actual number of the endnote is
% written to the external file as unexpanded tokens.  When, after you
% call |\theendnotes|, you read in the external file for the endnotes,
% for example |\jobname.ent|, all these tokens become a command to set
% the |\mark|.  Notice that there are two forms of this command, one
% for the standard document classes, one for memoir class.
% \textsf{edmargin} chooses which form depending upon which class is
% loaded.
