%  Based on the FOOTNOTES section of
%  LATEX.TEX (VERSION 2.09 - RELEASE OF 19 April 1986), with
%  "footnote" changed to "endnote" and "fn" changed to "en" (where
%  appropriate), with all the minipage stuff pulled out, and with
%  some small changes for the different operation of endnotes.
%  Subsequently updated to follow the code for
%  LaTeX2e <2000/06/01>.
%
%  Uses an extra external file, with .ent extension, to hold the
%  text of the endnotes.  This may be deleted after the run; a new
%  version is generated each time--it doesn't require information
%  collected from the previous run.
%
%  This code does not obey \nofiles.  Perhaps it should.

%  To turn all the footnotes in your documents into endnotes, say
%
%     \let\footnote=\endnote
%
%  in your preamble, and then add something like
%
%     \newpage
%     \begingroup
%     \parindent 0pt
%     \parskip 2ex
%     \def\enotesize{\normalsize}
%     \theendnotes
%     \endgroup
%
% as the last thing in your document.  (But \theendnotes all
% by itself will work.)

% JL  Modified to include \addtoendnotes.  JL, 10/22/89.
%
% JK  Modification by J"org Knappen 25. 2. 1991:
% JK
% JK  Introduced \notesname in the spirit of international \LaTeX.
% JK  \notesname is set per default to be {Notes}, but can easily
% JK  be redifined, e.g. for german language
% JK  \renewcommand{\notesname}{Anmerkungen}
%
% DW Modification by Dominik Wujastyk, London, 19 September 1991:
% DW
% DW Moved the line
% DW         \edef\@currentlabel{\csname p@endnote\endcsname\@theenmark}
% DW out of the definition of \@endnotetext and into the definition
% DW of \@doanenote so that \label and \ref commands work correctly in
% DW endnotes.  Otherwise, the \label just pointed to the last section
% DW heading (or whatever) preceding the \theendnotes command.
%
% JL Revised documentation and macros.  24 Sept 1991.
%
% modified by --bg (B.Gaulle) 09/14/94 for:
%               1) replace » (why a 8bit char here?) by ^ as a default.
%               2) force \catcode of > to be 12 (implied by \@doanenote).
%          by --bg again 03/22/95 for:
%               3) reseting appropriate catcode of > in case it were
%                  used as an active char before \@endanenote (was
%                  pointed by Ch. Pallier).
%
% John Lavagnino, 12 January 2003: a number of small updates:
%
% JL Incorporate change suggested by Frank Mittelbach to
% JL \enoteheading, so that first note has paragraph indentation.
% JL Frank's note:
%      the idea of this code is to fix the problem that without it
%      the first endnote after the heading will not be indented thus looking
%      somewhat strange. Problem however is that since there is no
%      indentation \leavemode\par will make an absolutely empty pargraph so
%      that no baseline calculation is done. therefore \vskip-\baselineskip
%      will put the first endnote directly below the heading without the
%      usual spaccing. using \mbox insead will cure this defect.
%
% JL Also incorporated Frank's suggestion to define
% JL \makeenmark and \theenmark, so that users can change more of the
% JL layout without using \makeatletter.  \makeenmark defaults to
% JL \@makeenmark, so old code is still supported; and \theenmark is
% JL just syntactic sugar for \@theenmark, which is still the real
% JL value (and shouldn't be directly modified by user code).
%
% JL Definition of \ETC. also dropped: surely nobody is still
% JL using TeX 2.992.  (If you are, you need to upgrade it or
% JL endnotes longer than 1000 characters will be truncated.)
%
% JL Update much of the code to track the current LaTeX2e code more
% JL closely. Clean up \theendnotes.
%
% John Lavagnino, 15 January 2003: fix my garbled version of
% Frank's updates.

%       ****************************************
%       *        ENDNOTE COMMANDS              *
%       ****************************************
%
%
%   \endnote{NOTE}       : User command to insert a endnote.
%
%   \endnote[NUM]{NOTE}  : User command to insert a endnote numbered
%                           NUM, where NUM is a number -- 1, 2,
%                           etc.  For example, if endnotes are numbered
%                           *, **, etc. within pages, then  \endnote[2]{...}
%                           produces endnote '**'.  This command does  not
%                           step the endnote counter.
%
%   \endnotemark[NUM]    : Command to produce just the endnote mark in
%                           the text, but no endnote.  With no argument,
%                           it steps the endnote counter before  generating
%                           the mark.
%
%   \endnotetext[NUM]{TEXT} : Command to produce the endnote but no
%                              mark.  \endnote is equivalent to
%                              \endnotemark \endnotetext .
%
%   \addtoendnotes{TEXT} : Command to add text or commands to current
%                              endnotes file: for inserting headings,
%                              pagebreaks, and the like into endnotes
%                              sections.  TEXT a moving argument:
%                              \protect required for fragile commands.
%
%       ****************************************
%       *        ENDNOTE USER COMMANDS         *
%       ****************************************
%
%   Endnotes use the following parameters, similar to those relating
%   to footnotes:
%
%   \enotesize   : Size-changing command for endnotes.
%
%   \theendnote : In usual LaTeX style, produces the endnote number.
%
%   \theenmark : Holds the current endnote's mark--e.g., \dag or '1' or 'a'.
%                 (You don't want to set this yourself, as it comes
%                 either from the autonumbering of notes or from
%                 the optional argument to \endnote. But you'll need
%                 to use it if you define your own \makeenmark.)
%
%   \makeenmark : A macro to generate the endnote marker from  \theenmark
%                  The default definition is \hbox{$^\theenmark$}.
%
%   \@makeentext{NOTE} :
%        Must produce the actual endnote, using \theenmark as the mark
%        of the endnote and NOTE as the text.  It is called when effectively
%        inside a \parbox, with \hsize = \columnwidth.  For example, it might
%        be as simple as
%               $^{\theenmark}$ NOTE

%  \theendnotes actually prints out the endnotes.

%  The user may want separate endnotes for each chapter, or a big
% block of them at the end of the whole document.  As it stands,
% either will work; you just say \theendnotes wherever you want the
% endnotes so far to be inserted.  However, you must add
% \setcounter{endnote}{0} after that if you want subsequent endnotes
% to start numbering at 1 again.

%  \enoteformat is provided so user can specify some special formatting
% for the endnotes.  It needs to set up the paragraph parameters, start
% the paragraph, and print the label.  The \mbox stuff in \enoteheading
% is to make and undo a dummy paragraph, to get around the games \section*
% plays with paragraph indenting and instead give us uniform
% indenting for all notes.
