%\section{Introduction}\label{sec:intro}
%
% The |hwexam| package and class supplies an infrastructure that allows to format
% nice-looking assignment sheets by simply including problems from problem files marked up
% with the |problem| package~\cite{Kohlhase:problem:ctan}.  It is designed to be
% compatible with |problems.sty|, and inherits some of the functionality.
% 
% \section{The User Interface}
% 
% \subsection{Package and Class Options}\label{sec:user:options}
% 
% The |hwexam| package and class take the options |solutions|, |notes|, |hints|, |pts|,
% |min|, and |boxed| that are just passed on to the |problems| package (cf. its
% documentation for a description of the intended behavior).
% 
% If the \DescribeMacro{showmeta}|showmeta| option is set, then the metadata keys are
% shown (see~\cite{Kohlhase:metakeys:ctan} for details and customization options).
% 
% The |hwexam| class additionally accepts the options |report|, |book|, |chapter|, |part|,
% and |showignores|, of the |omdoc| package~\cite{Kohlhase:smomdl:ctan} on which it is
% based and passes them on to that. For the |extrefs| option
% see~\cite{Kohlhase:sref:ctan}.
%
% \subsection{Assignments}
%
% This package supplies the \DescribeEnv{assignment}|assignment| environment that groups
% problems into assignment sheets. It takes an optional KeyVal argument with the keys
% \DescribeMacro{number}|number| (for the assignment number; if none is given, 1 is
% assumed as the default or --- in multi-assignment documents --- the ordinal of the
% |assignment| environment), \DescribeMacro{title}|title| (for the assignment title; this
% is referenced in the title of the assignment sheet), \DescribeMacro{type}|type| (for the
% assignment type; e.g. ``quiz'', or ``homework''), \DescribeMacro{given}|given| (for the
% date the assignment was given), and \DescribeMacro{due}|due| (for the date the
% assignment is due).
% 
% \subsection{Typesetting Exams}
%
% Furthermore, the |hwexam| package takes the option
% \DescribeMacro{multiple}|multiple| that allows to combine multiple assigment sheets into
% a compound document (the assignment sheets are treated as section, there is a table of
% contents, etc.). 
% 
% Finally, there is the option \DescribeMacro{test}|test| that modifies the behavior to
% facilitate formatting tests. Only in |test| mode, the macros |\testspace|,
% |\testnewpage|, and |\testemptypage| have an effect: they generate space for the
% students to solve the given problems. Thus they can be left in the {\LaTeX} source. 
%
% \DescribeMacro{\testspace}|\testspace| takes an argument that expands to a dimension,
% and leaves vertical space accordingly. \DescribeMacro{\testnewpage}|\testnewpage| makes
% a new page in |test| mode, and \DescribeMacro{\testemptypage}|\testemptypage| generates
% an empty page with the cautionary message that this page was intentionally left empty.
%
% Finally, the \DescribeEnv{testheading}|\testheading| takes an optional keyword argument
% where the keys \DescribeMacro{duration}|duration| specifies a string that specifies the
% duration of the test, \DescribeMacro{min}|min| specifies the equivalent in number of
% minutes, and \DescribeMacro{reqpts}|reqpts| the points that are required for a perfect
% grade.

%   good luck
% \end{testheading}
% \caption{A generated test heading.}\label{fig:testheading}
% \end{exfig}
% 
% \subsection{Including Assignments}
%
% The \DescribeMacro{\includeassignment}|\includeassignment| macro can be used to include
% an assignment from another file. It takes an optional KeyVal argument and a second
% argument which is a path to the file containing the problem (the macro assumes that
% there is only one |assignment| environment in the included file).  The keys
% \DescribeMacro{number}|number|, \DescribeMacro{title}|title|,
% \DescribeMacro{type}|type|, \DescribeMacro{given}|given|, and \DescribeMacro{due}|due|
% are just as for the |assignment| environment and (if given) overwrite the ones specified
% in the |assignment| environment in the included file.
% 
%
% \section{Limitations}\label{sec:limitations}
% 
% In this section we document known limitations. If you want to help alleviate them,
% please feel free to contact the package author. Some of them are currently discussed in
% the \sTeX TRAC~\cite{sTeX:online}. 
% \begin{compactenum}

%
% \section{Implementation: The hwexam Class}\label{sec:impl:cls}
%
% The functionality is spread over the |hwexam| class and package. The class provides
% the |document| environment and pre-loads some convenience packages, whereas the package
% provides the concrete functionality.
% 
% |hwexam.dtx| generates four files: |hwexam.cls| (all the code between
% {\textsf{$\langle$*cls$\rangle$}} and {\textsf{$\langle$/cls$\rangle$}}), |hwexam.sty|
% (between {\textsf{$\langle$*package$\rangle$}} and
% {\textsf{$\langle$/package$\rangle$}}) and their {\latexml} bindings (between
% {\textsf{$\langle$*ltxml.cls$\rangle$}} and {\textsf{$\langle$/ltxml.cls$\rangle$}} and
% {\textsf{$\langle$*ltxml.sty$\rangle$}} and {\textsf{$\langle$/ltxml.sty$\rangle$
% respetively}}). We keep the corresponding code fragments together, since the
% documentation applies to both of them and to prevent them from getting out of sync.
%
% \subsection{Class Options}\label{sec:impl:cls:options}
%
% To initialize the |hwexam| class, we declare and process the necessary options by
% passing them to the respective packages and classes they come from.
% 
%    \begin{macrocode}
%<*cls>
\DeclareOption{test}{\PassOptionsToPackage{\CurrentOption}{hwexam}}

%
% We load |article.cls|, and the desired packages. For the {\latexml} bindings, we make
% sure the right packages are loaded.
%
%    \begin{macrocode}
%<*cls>
\LoadClass{omdoc}

\RequirePackage{hwexam}
\RequirePackage{graphicx}
\RequirePackage{a4wide}

RequirePackage('amstext');
RequirePackage('amsmath');
%</ltxml.cls>
%    \end{macrocode}
%
% \section{Implementation: The hwexam Package} 
%
% \subsection{Package Options}
%
% The first step is to declare (a few) package options that handle whether certain
% information is printed or not. Some come with their own conditionals that are set by the
% options, the rest is just passed on to the |problems| package.
%
%    \begin{macrocode}
%<*package>
\DeclareOption{showmeta}{\PassOptionsToPackage{\CurrentOption}{metakeys}}
\newif\iftest\testfalse
\newif\ifsolutions\solutionsfalse
\DeclareOption{test}{\testtrue\solutionsfalse}
\newif\ifmultiple\multiplefalse
\DeclareOption{multiple}{\multipletrue}
\DeclareOption*{\PassOptionsToPackage{\CurrentOption}{problem}}
\ProcessOptions
%</package>
%    \end{macrocode}
% Then we make sure that the necessary packages are loaded (in the right versions).
%    \begin{macrocode}
%<*package>
\RequirePackage{keyval}[1997/11/10]
\RequirePackage{problem}
%</package>
%    \end{macrocode}
%
% Here comes the equivalent header information for {\latexml}, we also initialize the
% package inclusions. Since {\latexml} does not handle options yet, we have nothing to
% do. 
%    \begin{macrocode}
%<*ltxml>
# -*- CPERL -*-
package LaTeXML::Package::Pool;
use strict;
use LaTeXML::Package;
RequirePackage('problem');
%</ltxml>
%    \end{macrocode}
%
% Then we register the namespace of the requirements ontology
%    \begin{macrocode}
%<*ltxml>
RegisterNamespace('assig'=>"http://omdoc.org/ontology/assignments#");
RegisterDocumentNamespace('assig'=>"http://omdoc.org/ontology/assignments#");
%</ltxml>
%    \end{macrocode}
%
% \subsection{Assignments}
%
% We will prepare the keyval support for the |assignment| environment.
%
%    \begin{macrocode}
%<*package>
\addmetakey{assig}{number}
\addmetakey*{assig}{title}
\addmetakey{assig}{type}
\addmetakey{assig}{given}
\addmetakey{assig}{due}
%    \end{macrocode}
%
% The next three macros are intermediate functions that handle the case gracefully, where
% the respective token registers are undefined.
% 
% The |\given@due| macro prints information about the given and due status of the
% assignment. Its arguments specify the brackets. 
% 
%    \begin{macrocode}
\def\given@due#1#2{%
\ifx\assig@given\@empty\else\ifx\assig@due\@empty\else{#1}\fi\fi%
\ifx\assig@given\@empty\else{Given {\assig@given}}\fi%
\ifx\assig@given\@empty\else\ifx\assig@due\@empty\else{, }\fi\fi%
\ifx\assig@due\@empty\else{Due {\assig@due}}\fi%
\ifx\assig@given\@empty\else{\ifx\assig@due\@empty\else{#2}\fi}\fi}
%    \end{macrocode}
% 
% With them, we can define the central |assignment| environment. This has two forms
% (separated by |\ifmultiple|) in one we make a title block for an assignment sheet, and
% in the other we make a section heading and add it to the table of
% contents.
% 
% \begin{macro}{assignment@titleblock}
%   This macro prints the title block of a section. If the |multiple| package option is
%   given we make a section heading out of this, and if not, a title block. Note that as
%   |problem|s are numbered by section, we also set the section counter in the latter
%   case.
%    \begin{macrocode}
\ifmultiple
\def\assignment@titleblock{%
\@ifundefined{assig@number}{\stepcounter{section}}{\setcounter{section}{\assig@number}}%
\section*{\protect\document@hwexamtype~\arabic{section}:~\assig@title\given@due{\\(})}%

\large{\given@due()}
\end{center}}
\fi
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{assignment@process@keys}
%   this macro collects the keys from its arugment and corrects them from the outside.
%    \begin{macrocode}
\def\assignment@process@keys#1{\metasetkeys{assig}{#1}
\ifx\inclassig@title\@empty\else\def\assig@title{\inclassig@title}\fi
\ifx\inclassig@type\@empty\else\def\assig@type{\inclassig@type}\fi

\ifx\inclassig@given\@empty\else\def\assig@given{\inclassig@given}\fi}
%    \end{macrocode}
% for this to work we need to define the |\inclassig| macros in case no
