+% \begin{abstract}
+%  \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. And attaching line numbers to prose involves 
+% doing things which might make other tasks in \LaTeX\ more 
+% difficult, such as writing the text to a box and peeling off one 
+% line at a time. \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 a textual note which 
+% appears on page 563 of the endnotes section for textual 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 Erdman and Harold Bloom in their edition of 
+% the Collected Poetry and Prose of William Blake. \textsf{edmargin} 
+% can also make notes with markers in the text, in the traditional 
+% fashion.
+%
+% \textsf{edmargin} requires the following packages to work correctly:
+% with the standard document classes, or the komascript classes:
+% \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{endnotes} and
+% \textsf{ifthen}.  You might wish to call \textsf{memoir} with the
+% oldfontcommands option.
+%
+% \section{Setup} \DescribeMacro{\setupendnoteheaders}
+% |\setupendnoteheaders| opens an external file to receive each of the
+% three preset kinds of endnote.  \textsf{edmargin} opens 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 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 set the |\mark| for that page of the
+% endnotes using the |\pageref| to the label in the main text it has
+% just defined.
+%
+% \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 of the
+% emendations, textual collations, and explanatory 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
+% running header, so if any sections follow these (the bibliography, 
+% for instance) be sure to restore your prevailing headings style by 
+% issuing, for example, |\pagestyle{headings}|
+% |\thispagestyle{empty}|. 
+%  
+%
+% \DescribeMacro{\notesbychapter} |\notesbychapter| 
+% % resets all the note 
+% % counter every time you issue a |\chapter| command, and it 
+% 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.  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 \LaTeX\ 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.
+%
+% \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.
+%
+% \section{Predefined Endnote Sections}
+% \textsf{edmargin} comes with three predefined endnotes sections and 
+% three predefined kinds of endnote, |\textnote{}|, |\emendation{}|, 
+% and |\explanatory{}|. 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{\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, include
+% an |\addtocontents| line just before you issue |\theendnotes|, the
+% command which will read all of your endnotes into your document at
+% that point.  For instance, I set 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 |\theendnotes|, issue
+% |\addcontentsline{toc}{chapter}{\protect\numberline{}\the\textnotescontentsname}|.
+%
+% \DescribeMacro{\textnote} \DescribeMacro{\explanatory} 
+% \DescribeMacro{\emendation} Use |\textnote| and its siblings as you 
+% would use an ordinary |\endnote|. If you are using a lemma, you 
+% must include it in the text of 
+% the note: |\textnote{lemma text] 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 can feel free 
+% to send this way to the endnote sections commands this way to the 
+% endnote sections 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.
+%
+% \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 
+% I the case in which marginal references were used. 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|.
+%
+% \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.
+% 
+% \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.

+%    \begin{macro}{\checknoteheaders}
+% This macro sets the counter notepageholder to the value given by the
+% pageref of the note that is being output.  All that strange business
+% with |\string| is there because I want to use the |\immediate\write|
+% mechanism to control what gets expanded and what doesn't get
+% 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.
