% \section{Introduction}
%
% This package is my attempt at writing a set of macros for creating exams.
% The package can be used with or without \textsf{web} or
% \textsf{exerquiz}. When used without, what is produced is a document
% suitable for printing. When \textsf{exerquiz} is used, the same document
% is produced, but with hypertext links to solutions. This may be useful
% for publishing solutions on the web, or publishing pretests with/without
% solutions.
%
% The package must be as flexible as possible vis-\`a-vis PDF. (1)
% \textsf{web} only does not add much, it does input hyperrref and test
% info such as \cs{title}, \cs{subject}, etc are placed in the Document
% Info fields of the PDF. (2) If \textsf{exerquiz} is also input (prior to
% \textsf{eqexam}), then hyperlinks will be created to the solutions to the
% test, if solutions are included at the end of the document. (3) If
% \textsf{web} and \textsf{exerquiz} are input, and the \texttt{online}
% option is taken, then the checkboxes will be come interactive, the space
% left to work the problems will be multi-line text boxes, fill-ins limited
% to True/False and simple text fill-in the blank will also become text
% boxes.
%
% When in \texttt{online} mode, the student can take the test in a computer
% lab, the completed exam can be printed and handed in, or perhaps
% submitted server-side script.
%
% \medskip\noindent
% (2011/05/13) The version of \textsf{eqexam} is a departure from previous
% versions. Previously, the list of problems were not in list, they were
% left-justified, with the problem number extending out into a little area
% determined by \cs{oddsidemargin}. This makes it hard to reformat a list
% of problems to fit into a custom book format.  This new version defines a
% new environment, \texttt{eqequestions}, that makes each problem into a
% list. The list environment allows for an easy redesign of the formatting
% of the problems. The purpose of this new scheme, is to open up
% \textsf{eqexam} as a format package that can be used by author for
% writing a textbook.

% \section{Required Packages}
% The following are the required packages for \textsf{eqexam}.
%    \begin{macrocode}
\RequirePackage{amstext,amssymb}
%    \end{macrocode}
% Bring the \texttt{comment} package in early, before \texttt{verbatim}, these two
% clash a bit.
%    \begin{macrocode}
\RequirePackage{comment}
%    \end{macrocode}
% (2011/05/08) Just before the file is closed and input, we write the end
% of the \texttt{eqequestions} environment, \verb!\end{eqequestions}!.
%    \begin{macrocode}
%\AtEndDocument{\writeEndEqeQuestions}
%    \end{macrocode}
% The macro \cs{includeexersolutions} is defined in \textsf{eqexam.def}. We execute
% the command \cs{include@solutions} before the web package is loaded. The \textsf{web} package
% has a \cs{AtEndDocument} as well, and inserts a new page that we don't want.

% We input \textsf{exerquiz} with the \texttt{nodljs}, we don't need all the JavaScript

% margins and spacing.
%    \begin{macro}{\eqexammargin}

%    \begin{macro}{\forVersion}
% Here is the command that does all the work. It creates alternate
% text macros for each of the versions declared using \cs{numVersions}.
%
% For example, assuming |\numVersions{3}| appeared earlier, the
% command |\forVersion{a}| (or |\forVersion{A}|) defines $3$ text commands \cs{vA}, \cs{vB} and
% \cs{vC}, each taking one argument, the text you want to display:
%\begin{verbatim}
% Name the \vA{place}\vB{date}\vC{year} of the signing of the Declaration
% of independence.
%\end{verbatim}
% Since we said |forVersion{a}| only the \cs{vA} text
% is displayed, the others are gobbled up, etc. But wait, the \cs{forVersion}
% does more than that! It also creates a series of comment environments
% |\begin{verA}/\end{verA}|, |\begin{verB}/\end{verB}|, |\begin{verC}/\end{verC}|, etc.,
% where only the version for which this compile applies will be typeset,
% the others are commented out.
%\begin{verbatim}
%\numVersions{3}
%\forVersion{b}
%...
%\begin{document}
%...
% Solve the equation for $\vA{x}\vB{y}\vC{z}$:
%\[

% \subsection{Insert Points in Margins and Compute Page Totals}
% Here we attempt to place point values of a problem in the margins and
% to compute the page totals.
%
%\begin{macro}{\probvalue}
% This is a fundamental macro for keeping track of the points of the problem.
% It increments the counter \texttt{eqpointvalue}, which keeps a running total
% of the points of the current part of the exam, puts the value in the margins,
% and sets a \texttt{mark}, so that at the end of the page, we can compute the
% number of points on the current page. This macro is used in several situations,
% for example, in the \texttt{problem} environment, \cs{manualcalcparts} and in
% \cs{autocaleparts}. \textbf{Should not be redefined}.
%\begin{flushleft}
%Parameters
%\begin{verbatim}
%#1 = total points for this problem
%#2 = 0 if total points, otherwise, #2 is the number of points each
%     problem.

%\subsection{Computing Number of Points within a Segment of the Exam}
%
% We add some commands for calculating number of points in a segment of the exam.
% A segment being defined subset of consecutive problems within an exam. We can
% define segments by placing markers (using \cs{placeMarkerHere}) between problems. We can
% then calculate the total number of points between markers.
%
% The counter below is a scratch counter for making the calculations. We assume the
% \texttt{calc} package is loaded, it does the work for us.
%
%    \begin{macrocode}
\newcounter{markerCnt}
%    \end{macrocode}
%    \begin{macro}{\placeMarkerHere}
% Placed outside of any \texttt{problem}/\texttt{problem*} environment, this command
% takes one argument, the symbolic name for this marker. We write to the auxiliary file
% and define a command whose name is based on \texttt{\#1}, and whose value is
% the cumulative total \cs{theeqpointvalue}.
%\changes{v1.8}{2008/11/02}
%{
%  Added a set of commands \cs{placeMarkerHere}, \cs{calcFromMarkers},
%  and \cs{markerTotalFmt} to enable the calculation of totals of segments
%  of the exam.

%    \begin{macro}{\calcFromMarkers}
% Once the markers are in place, we can calculate the number of points defined between

% \texttt{\#3} are the symbolic names of the two markers. While, \texttt{\#1} is an optional

% What are my goals/desired features? Modern (U.S.) textbooks---at least
% the ones I'm familiar with---consist of some or all of the following
% resources:
% \begin{itemize}
%    \item \textbf{Student Edition}: Answers to odd-numbered problems
%    appear in the back of the text.
%    \item[] We need to have a scheme where odd-numbered problems, under suitable options,
%    are compiled. \textbf{Goal:} It does not need to be restricted to odd-numbered, however, need to latex only
%    those problems that meet the ``include'' criteria.
%    \item[] For chapter review problem sets, odd-number problems are have solutions in the
%    back of the book.
%    \item[] For chapter quizzes, odd-numbered (optionally all) solutions
%       are in the back of the book.
%
%    \item \textbf{Instructor Edition}: Answers to all problems appear in
%    the back of the book. Answers may also appear in the body of the text,
%    in the margins of the text, or immediately after the statement of the
%    problem. If the answer is too long, there is a cross-reference to the
%    solution in the appendix.
%    \item[] Some publishers I've seen have wide margins where additional material can be inserted
%    (historical sketches, instructor notes, pictures, etc.). In these margins, the answers to the problems
%    can appear. Other publishers put answer immediately
%    following the questions. The latter is easy to do; just have a macro, say \verb!\ANS{$12.5$}!, which only
%    expands when the ``instructor'' option is used.
%    \item \textbf{Student Solution Manual}: Contains solutions to all
%    odd-problems, as well as any review problems and chapter quizzes.
%    Some publishers include all solutions to chapter quizzes.
%   \item[] A solution manual is a separate publication. This document would be
%       created by latexing one or more of the auxiliary file (\texttt{.sol})
%       These files might have to be edited before the final compile. We include only the solutions
%       that meet the include criteria (i.e., odd-numbered ones).
%   \item[] The current features of \textsf{eqexam} is what is needed here. The authors need only
%       include solutions to each problem in a \texttt{solution} environment. Now, I realize that often times
%       the authors create the solutions, but someone else, possibly a grade student or contractor, solves the problems.
%       In the latter case, the authors would probably not like to turn over the source files to the one solving and typesetting
%       the problems.
%    \item \textbf{Instructor Solution Manual}: Contains solutions to all
%    problems, review problems, chapter quizzes.
%   \item[] Similar comments for the instructor solution manual.
% \end{itemize}
% Some other thoughts by a contributor:
% \begin{itemize}
%\item Often there is a diagram or graphic within the problem -- this has
%    some figure caption and after the running counter of the figure it is
%    named the NUMBER of the problem (cross-reference to the problem number)
%
%\item Often the probs with soln are setup in two-column style.
%
%\item Often the PROBLEM NUMBER has a special formatting (not only bold and
%    black), maybe with a colorframebox around or some special formatting
%    from the author
%
%\item Of course I have seen in some EXAMPLES that there is a wide margin
%    to put in additional graphics etc. setup in two-side style -- wide left
%    margin on even pages, wide right margins on odd pages. Here as well
%    are captions setup and cross-references.

% \subsection{Marginal Matter.} There are three levels in the margins:
% \begin{enumerate}
%   \item \textbf{Top level}: This is a command \cs{tbTopMargin} with may be
%          redefined between pages. It should have the width of the \cs{parbox}
%          that contains all the content of the margin, this width is \cs{tb@marparboxwidth}
%          (\texttt{\cs{oddsidemargin}-\cs{marginparsep}}). The content \emph{must} be
%          unbreakable across pages. The content of \cs{tbTopMargin} will appear \emph{on
%          every page subsequent to its definition}.
%    \item[] \DescribeMacro{\clearTopMargin} We can clear the top level using the following command
%    \begin{macrocode}
\newcommand{\clearTopMargin}{\global\let\tbTopMargin\relax}
%    \end{macrocode}
%    \item[] Clearing will take effect on the following page.
%    \item[] \DescribeMacro{\setTopMargin} As a convenience macro, we can create top margin content.
%            Redefinitions will appear on the next page from where the definition was made.
%    \begin{macrocode}
\newcommand{\setTopMargin}[1]{\gdef\tbTopMargin{#1}%
    \gdef\tbSaveTopMargin{#1}}
\let\tbTopMargin\@empty
\let\tbSaveTopMargin\@empty
%    \end{macrocode}
%    \item \textbf{Middle level}: The middle level is the most interesting. You write to it
%          using \cs{insMidMarg}. Normally, this is text. If there is too much text,
%          it will be split off and placed in the middle level of the next page. The command
%          \cs{ANS} also writes to the middle level when the \texttt{instred} and \texttt{marginans} options are
%           taken.
%    \item \textbf{Bottom level}: This is similar to the top level, but on the bottom. The
%         command is named \cs{tbBotMargin} and follows the same rules as \cs{tbTopMargin}.
%         Again, the content of \cs{tbBotMargin} will appear \emph{on every
%         page subsequent to its definition}.
%    \item[] \DescribeMacro{\clearBotMargin} We can clear the bottom level using the following command
%    \begin{macrocode}
