+% \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.
+%
+% The \texttt{fortextbook} option supplies support for authors writing a
+% textbook. The \texttt{exam} environment is re-cast into the
+% \texttt{probset} environment, it can be used to write problem sets within
+% the text. there is a version for the instructor and the student. The
+% instructors version writes answers to the problem sets to the margins (or
+% inline). Two solutions are offered, short and long. The short solutions
+% appear in the back of the book (odd-numbered ones for the student edition.
+% The long solutions are used to build the stand-alone solutions manuals for
+% both the student and the instructor. More details are found in
+% \Nameref{fortextbook}, see also \Nameref{fortextbookstyle}.
+%
+% \newpage
+% \section{Package options and Process Options}
+% Let us catalog the options of this package.
+%
+% \subsection{Early inclusion of packages}
+% We include these packages early in the process of loading.
+% \begin{macrocode}
+%<*package>
+% \end{macrocode}
+%\changes{v3.1b}{2012/06/18}{New requirement \textsf{ifpdf}}
+% \begin{macrocode}
+\RequirePackage{ifpdf}[2006/02/20]
+\RequirePackage{ifxetex}[2006/08/21]
+% \end{macrocode}
+% Very useful package for defining key-values.
+% \begin{macrocode}
+\usepackage{xkeyval}
+% \end{macrocode}
+%
+% \subsection{Options New to \textsf{eqexam}}
+% Here are some options unique to this package.
+% \IndexOpt{usecustomdesign}
+% Use this option to avoid \textsf{eqexam} from setting up the ``standard'' page layout.
+% \begin{macrocode}
+\DeclareOptionX{usecustomdesign}{\eqcustomdesigntrue}
+\newif\ifeqcustomdesign \eqcustomdesignfalse
+\DeclareOptionX{nocustomdesign}{\let\eqe@nocustomdesign=1}
+\let\eqe@nocustomdesign=0
+% \end{macrocode}
+% \IndexOpt{fortextbook}
+% An option to extend the application of \textsf{eqexam} to provide support
+% (exercises, providing solutions, short solutions, answers, and hints) for
+% authors writing textbooks. See \Nameref{fortextbook}.
+% \begin{macrocode}
+\DeclareOptionX{fortextbook}{\eqfortextbooktrue}
+\newif\ifeqfortextbook \eqfortextbookfalse
+% \end{macrocode}
+% \IndexOpt{forinstr}
+% \IndexOpt{forstudent}
+% These two options simply set a switch to signal the intention of the
+% document author.
+% \begin{macrocode}
+\DeclareOptionX{forinstr}{\eqforinstrtrue}
+\DeclareOptionX{forstudent}{\eqforinstrfalse}
+\newif\ifeqforinstr \eqforinstrfalse
+% \end{macrocode}
+% \IndexOpt{nomarginwrite}
+% The switch \cs{ifeqwritetomargins} is used by the \texttt{fortextbook}
+% option. It is normally \texttt{true}, but if set to \texttt{false}, the
+% \cs{AddToShipoutPicture} is not generated at the beginning of the
+% document. Here is the code taken from below:
+%\begin{verbatim}
+% \ifeqfortextbook\ifeqwritetomargins
+% \AtBeginDocument{\chkmarginboxwidth
+% \AddToShipoutPicture{\eqe@tb@shipout}}
+% \fi\fi
+%\end{verbatim}
+% Using this option, the check for the margin width is not done,
+% and writing to the margins is turned off.
+% (\cs{marginpar} still works)
+% \begin{macrocode}
+\DeclareOptionX{nomarginwrite}{\eqwritetomarginsfalse}
+\newif\ifeqwritetomargins\eqwritetomarginstrue
+% \end{macrocode}
+%
+% \paragraph*{Configuration Files.}
+% This section contains options for the configuration files.
+% \IndexOpt{cfg}

+% \IndexOpt{vspacewithsolns}
+% When \texttt{vspacewithsolns} is used, vertical space is created by

+% Added the \texttt{vspacewithsolns} option}
+% \IndexOpt{ftbsolns}
+% Added \texttt{ftbsolns} as an alias for \texttt{vspacewithsolns}
+% \changes{v3.0h}{2011/08/17}{% 2011/08/17 v3.0h Added the
+% \texttt{vspacewithsolns} option}. This is implemented through
+% a Boolean switch \cs{ifvspacewithsolns}, which I'm sorry now I've made
+% so long. To make up for that bad decision, I also define
+% \DescribeMacro{\ifkeyalt}\cmd{ifkeyalt} to be \cmd{\ifvspacewithsolns}
+% with making conditional decisions, of course, one cannot say
+% \cs{keyalttrue}.
+% \begin{macrocode}

+% allow you to set the version information though a package option. This allows us, for

+% This feature is used primarily by \textsf{AeB Exam Builder}.
+% \changes{v2.0}{2010/03/05}
+% {%

+% \begin{macro}{\endshortTitleText}
+% Next we state the long and short titles for our document,
+% one for each of our declare number of versions given earlier.
+% For example, we can use the value \cs{nExam} in out titles. Usage:
+%\begin{verbatim}
+% \longTitleText

+% \shortTitleText
+% {T\nExam A}
+% {T\nExam B}
+% {T\nExam MU}

+% I've added markers that delimit the end of the arguments. In this
+% way, the end of the list of titles can be detected, even though
+% the number of titles is not the same as what is declared by the

+%
+% If there are more titles than what is declared, the rest are absorbed (gobbled).
+% If there are fewer titles than declared, a {\LaTeX} package error is generated,
+% and substitute titles are generated.

+% 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}

+% \section{Identification Information}
+% We define a series of commands in support of building an exam: Lines to identify
+% the student and his/her student id (SID), the instructors email address, the name of the
+% test and the course.
+%\par\medskip
+%\noindent\DescribeMacro{\eqExamName}\DescribeMacro{\examNameLabel} provides a line for the student to enter his/her name into the
+% exam. The command \cs{examNameLabel} can be used to define the name label, the default
+% is \texttt{Name:}
+%
+% Will insert a text box as well if the \texttt{option} is taken in addition
+% to \texttt{nosolutions} and with \texttt{solutionsafter} not taken.
+% This macro defines \cs{eq@ExamName}, which actually contains the code.
+% The first (optional) parameter is passed to \cs{insTxtFieldIdInfo}, and can be
+% used to change the appearance of the text field created; the second required parameter
+% is the width of the field.

+% \DescribeMacro{\eqEmail} provides a line for the student
+% to enter his/her email address. Useful for documents submitted by email, the
+% instructor can reply.
+%
+% Will insert a text box as well if the \texttt{option} is taken in addition
+% to \texttt{nosolutions} and with \texttt{solutionsafter} not taken.

+% \DescribeMacro{\insTxtFieldIdInfo} The above macros (\cs{eqExamName}, \cs{eqSID} and \cs{eqEmail})
+% all call this macro, which inserts a Acroforms text field if the \texttt{option} is taken in addition
+% to \texttt{nosolutions} and with \texttt{solutionsafter} not taken.
+%
+% The first (optional) parameter is used to change the appearance of the text field.
+% The second parameter is the width of the field, and the third is the field name.

+% \end{macrocode}
+% \DescribeMacro{\SubmitInfo} is required when the \texttt{email} option is taken,
+% and should appear in the preamble. The first argument is the URL to the \textsf{eqAttach.asp}
+% code on the server, and the second is the email of the instructor is to receive the results.
+% (Multiple recipients can be specified by separating each with a comma.)
+% \begin{macrocode}
+\def\SubmitInfo#1#2{%
+ \def\EqExam@SubmitURL{#1}\def\@EmailInstr{#2}%

+% \end{macrocode}
+% \DescribeMacro{\EmailCourseName} is used to specify the course name of the course. The default
+% value for this is \cs{websubject}, obtained from the \cs{subject} macro used in the preamble; however,
+% if you want a different name in the email, perhaps with more information included, you can redefine
+% the value using this macro.
+% \begin{macrocode}
+\def\EmailCourseName#1{\def\@EmailCourseName{#1}}
+% \end{macrocode}
+% Here's the default value.
+% \begin{macrocode}
+\EmailCourseName{\websubject}
+% \end{macrocode}
+% \DescribeMacro{\EmailExamName} is used to specify the exam name of the course. The default
+% value for this is \cs{webtitle}, obtained from the \cs{title} macro used in the preamble; however,
+% if you want a different name in the email, perhaps with more information included, you can redefine
+% the value using this macro.
+% (Multiple recipients can be specified by separating each with a comma.)
+% \begin{macrocode}
+\def\EmailExamName#1{\def\@EmailExamName{#1}}
+% \end{macrocode}
+% Here's the default value.
+% \begin{macrocode}
+\EmailExamName{\webtitle}
+% \end{macrocode}
+% \DescribeMacro{\EmailSubject} The document author mail want a custom subject in the email, instead
+% of the standard one. By using this macro, he can design his own email subject.
+% \begin{macrocode}
+\def\EmailSubject#1{\def\@EmailSubject{#1}}
+% \end{macrocode}
+% Here's the default value, which generates no custom subject line.
+% \begin{macrocode}
+\EmailSubject{}
+% \end{macrocode}
+% In this case \textsf{eqAttach.asp} inserts the standard one.
+%\begin{verbatim}
+%Exam Results: \webtitle of \websubject
+%\end{verbatim}
+% The email would read like ``\texttt{Exam Results:~Test 1 of Calculus I}'', for example.
+%
+% \DescribeMacro{\ServerRetnMsg} Unless submitted in \texttt{silent} mode, the \textsf{eqAttach.asp}
+% returns a message acknowledging the receipt of the data. \cs{ServerRetnMsg} is used to customize
+% this message.
+% \begin{macrocode}
+\def\ServerRetnMsg#1{\def\@ServerRetnMsg{#1}}
+% \end{macrocode}
+% Here's the default value, which generates no custom return message
+% \begin{macrocode}
+\ServerRetnMsg{}
+% \end{macrocode}
+% \noindent\DescribeMacro{\SubmitButtonLabel} is the label that appears on the submit button.
+% \begin{macrocode}
+\def\SubmitButtonLabel#1{\def\@SubmitButtonLabel{#1}}
+% \end{macrocode}
+% Here's the default value.
+% \begin{macrocode}
+\SubmitButtonLabel{Submit}

+% \DescribeMacro{\SubmitButton} is the macro that provides the submit button
+% when the \texttt{email} option is taken. It appears automatically at the top of

+%
+%\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

+% \item Defined \cs{eqe@leadinitem}, \cs{eqe@@leadinitem}, and \cs{leadinitem} below.
+% The first one mostly tests whether we are permitted to use the \cs{leadinitem} command.
+% If \cs{solutionparshape} is empty, the command may be used. (This gives a restriction
+% of only one use per a single \texttt{problem*} environment.) Control is passed
+% to \cs{eqe@@leadinitem} which does all the work.
+% \item In the definition of \cs{pr@blem@star} (part of the startup for \texttt{problem*} we
+% say \verb!\let\leadinitem=\eqe@leadinitem!
+% \item In the startup code for \texttt{exercise@parts@list} (\texttt{exerquiz})
+% lines containing \cs{solutionparshape} and \verb!\let\leadinitem\eq@leadinitemparts!
+% are found. Also, when the \texttt{parts} environment is complete, we restore the
+% default definition of \cs{leadinitem}, \verb!\let\leadinitem\leadinitem@external!.
+% \item In the definition of \cs{eqe@@leadinitem}, we also define \cs{solutionparshape}
+% to help control the paragraphs for this delicate problem of a lead-in item. Its
+% normal definition is \cs{@empty}, and this fact used to detect whether the document
+% author is trying to use two \cs{leadinitem}s in one \texttt{problem*} environment.
+%\item At the beginning of the definition of the command \cs{@exercise} (in \textsf{exerquiz}
+% we \cs{let} \cs{solutionparshape} to \cs{@empty}.
+% \item So too does \cs{solutionparshape} appear in the definition of
+% \cs{vspaceFmt} (\textsf{exerquiz}).
+% \item \cs{solutionparshape} use used to correctly format in the \texttt{solutionsafter},
+% found in \cs{solnexer@@@woparts} (\textsf{exerquiz}).

+% \section{Concerning the \protect\texttt{fortextbook} option}\label{fortextbook}
+%
+% 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.
+%\end{itemize}

+% \subsection{Macros to display answers/shortsolns}
+% In this section, we develop some commands to display answers or short solutions. These

+% Let us begin by creating a simple macro for saving an answer. The answer is displayed ``in-line.''
+% No verbatim-type text allowed, no unbalanced braces unless escaped. \cs{ANS} displays the answer
+% if the \texttt{instred} option of the \texttt{eqe@tbopts} family, i.e., by executing
+%
+% \begin{macro}{\bGrpANS}
+% \begin{macro}{\eGrpANS}

+% \end{macro}
+% \end{macro}
+% \cs{ANS} begin by checking to see if there is a star that follows the command,
+% this is used for inline answers. If \texttt{*} is present, we do not put the
+% answer inline, but will put it in the margins if the option call for it.

+% the commands \cs{bGrpANS} and \cs{bGrpANS}. We keep this to revert to this definition
+% if this new feature causes problems.

+% \DescribeMacro{\ftb@defineInsSpan} is used when there is an optional

+% \end{macrocode}
+% \DescribeMacro{\ftb@spanPrts} calculates the letter of the end of the

+% \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}

+ #1\color@endgroup}}
+\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}.

+% \subsection{Commands in support of Solution Manuals}
+% Generally, the solution manual source file should have the same
+% packages as the source file for the book itself, perhaps with a few exceptions,
+% but definitely the \textsf{eqexam} package is required with its \texttt{fortextbook} option.
+%
+% At this time, we provide only two commands, these are \cs{ftbInputBookAux} and
+% \cs{ftbInputSolnFiles}.
+% \begin{macro}{\ftbInputBookAux}
+% This command is used to input the auxiliary files of the master source file. It takes
+% one argument, the name of the master source file (\texttt{myBook.ltx} or \texttt{myBook.tex}).
+% If the extension is not present, it is assumed to be \texttt{.tex}.

+% \end{macrocode}
+% In the next 4 lines, we save \cs{@writefile} and \cs{@setckpt}, and \cs{let}
+% them to \cs{@gobbletwo}. We restore their definitions after we input the aux files.
+% We include the aux files of the source file in case there are some cross references
+% in the solution files, or the body of the text would like to refer back to the
+% original book. (Seems unlikely.)

+% \begin{macro}{\ftbInputSolnFiles}
+% In the body of the text, place \cs{ftbInputSolnFiles} in vertical mode.
+% This will input the \texttt{.sol} file of the master source document.
+% The optional argument is the name of the solution file. The default name
+% is \verb!\tbBaseName.sol!, where \cs{tbBaseName} was defined in
+% \cs{ftbInputBookAux}. If no extension is specified, an extension of \texttt{.sol}
+% is assumed. The original \texttt{.sol} may have changed its name, if someone
+% renamed it (to keep it from being overwritten). The solution file may be editing (by hand)
+% as needed.
