% Tim Morgan with many suggestions, bug fixes, etc, from Marshall Rose
% Based originally on Michael Spivak's AMSPPT.STY.

% When edits are made to this file, the version number should be incremented.
\def\version{103}
\let\fmtversion=\version	% These two control sequences are defined
\def\fmtname{dissertation}	% in plain.tex, so we do it here too.

% Assumes the following hidden definitions from plain.tex:
%	\z@ is defined from plain.tex as 0pt (and magically can
%		be used as the integer constant 0 also).
%	\p@ is the same, but 1pt
%	\@ne is 1
%	\m@ne is -1
%	\tw@ is 2
%	\thr@@ is 3
%	\@m is 1000
%	\@M is 10000
% And the following scratch register definitions:
%	\dimen@ is \dimendef'd to be \dimen0
%	\skip@  is \skipdef'd to be \skip0
%	\count@ is \count255

\catcode`\@=11		     % So we can use a special character

%  TABLE of CONTENTS Macros  %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% This set of macros allows you to build a table of contents for a document
% automatically in TeX.  There are only three control sequences which you
% will need to use.  The first is \inicont, which initializes the macros.
% This package works by writing the appropriate lines into a file called
% \jobname.toc in your account.  This file is read by \printcontents or
% by \printcont in PRINT-PRELIM.TEX.
%
\newwrite\cont@file			% Get a free channel to write to
\newif\ifcont@closed
\cont@closedtrue			% Haven't opened contents file yet
\newwrite\fig@file
\newwrite\tab@file
\newif\iffig@closed

\newif\iftab@closed

\def\contitle{\jobname.toc}		% Default name of contents file

% Citations:
% We keep a running list, \ref@set, which is
% all the things which were \cite'd throughout the paper, with
% only one entry for each different key.
%
% There are three versions of each of the citation
% commands:
% 1. The \def'd version is the normal one used throughout the paper.
% 2. Within a figure, table, etc,'s caption, because of the use of
%    \def and \edef, a special version which just produces the
%    citation without the \gaddtolist command is used.  These
%    definitions are predefined, and are \let to be \cite etc with
%    \no@cites, for speed.
%
% When the user requests a citation with key, we first look it up
% in a translation table called \key@table, organized as a list of
% <key, printed-key> pairs, to see if it really should be
% printed differently.  The user can specify this translation table using
% the \printkey command.  If a key is not in the table, it is printed
% as-is.

% We keep the dimension \key@size as the largest printed key so far.
% This value can then be used to print the keys in the bibliography
% optimally, rather than just trying to guess.  Each time we print a
% (in \use@key), we see if it's longer than \key@size, and if so then
% we set \key@size = its width.

% The basic strategy is as follows.  We read the bib. file, which is
% assumed to be in sorted order of keys/author names.  Each
% entry is of the form \ref{key}.  We see if that key is in the table
% \ref@set, which is a table of all the keys we've \cite'd.  If the key
% isn't in the list, we print it in parens and go on to the next entry.
% Otherwise, we print the key in square brackets, and format the
% bibliography entry according to the format (JACM or IEEE).  We print a
% warning if the key is in the \ref@seen list.  We add the key to
% the \ref@seen list.  The key is removed from the \ref@set list if it
% was there.  At the end of the references (\endreferences), we check
% if there are any keys left in \ref@set.  If so, the bib. file was
% deficient, and we print a warning message (it should probably be a
% fatal error message).
