+%
+%\section{Introduction}\label{sec:intro}
+%
+% The |assignment| package supplies an infrastructure that allows to format nice-looking
+% assignment sheets by simply including problems from problem files marked up with the
+% |problem| package. It is designed to be compatible with |problems.sty|, and inherits
+% some of the functionality.
+%
+% \section{The User Interface}
+%
+% \subsection{Assignments}
+% \DescribeEnv{assignment} This package supplies the |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).
+%
+% \DescribeMacro{\CourseTitle} |\Coursetitle{|\meta{title}|}| can be used to specify the
+% title of the course. It is usually specified in the driver file.
+%
+% \DescribeMacro{\AssignmentType} Similarly, |\AssignmentType{|\meta{type}|}| can be used
+% to specify the default assignment type.
+%
+% The |assignment| package takes the options \DescribeMacro{solutions}|solutions|,
+% \DescribeMacro{notes}|notes|, \DescribeMacro{hints}|hints|, \DescribeMacro{pts}|pts|,
+% \DescribeMacro{min}|min|, and \DescribeMacro{boxed}|boxed| that are just passed on to
+% the |problems| package (cf. its documentation for a description of the intended
+% behavior).
+%
+% \subsection{Typesetting Exams}
+%
+% Furthermore, the |assignment| 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 \DescribeMacro{\testheading}|\testheading| takes a keyword argument where
+% the keys |duation| specifies a string that specifies the duration of the test, |min|
+% specifies the equivalent in number of minutes, and |reqpts| the points that are required
+% for a perfect grade.
+% \begin{exfig}[ht]
+% \makeatletter
+% \@problem{1.1}{4}{10}
+% \@problem{2.1}{4}{8}
+% \@problem{2.2}{6}{10}
+% \@problem{2.3}{6}{10}
+% \@problem{3.1}{4}{8}
+% \@problem{3.2}{4}{8}
+% \@problem{3.3}{2}{4}
+% \makeatother
+% \begin{verbatim}
+% \testheading{duration=one hour,min=60,reqpts=27}
+% \end{verbatim}
+% \vspace*{-3ex}\hrule\vspace*{.5ex} formats to\vspace*{1ex} \hrule\par\noindent\vspace*{2ex}
+% \testheading{duration=one hour,min=60,reqpts=27}
+% \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.
+%
+% \StopEventually{\newpage\PrintChanges}
+% \newpage
+%
+% \section{The Implementation}
+%
+% \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>
+\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>
+\omdaddkey{assig}{number}
+\omdaddkey{assig}{title}
+\omdaddkey{assig}{type}
+\omdaddkey{assig}{given}
+\omdaddkey{assig}{due}
+%</package>
+% \end{macrocode}
+%
+% The next macro just sets the internal token register to the intended string.
+%
+% \begin{macrocode}
+%<*package>
+\def\AssignmentType#1{\gdef\assig@default@type{#1}}
+\def\assig@default@type{Assignment}
+%</package>
+%<*ltxml>
+%</ltxml>
+% \end{macrocode}
+%
+% The next three macros are intermediate functions that handle the case gracefully, where
+% the respective token registers are undefined.
+%
+% \begin{macrocode}
+%<*package>
+\def\Assig@Type{\ifx\assig@type\@empty\assig@default@type\else\assig@type\fi}
+\def\Assig@Title{\ifx\assig@title\@empty\else\assig@title~\fi}
+% \end{macrocode}
+%
+% 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}
+%</package>
+% \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{environment}{assignment}
+% \begin{macrocode}
+%<*package>
+\newenvironment{assignment}[1][]% keyval args
+{\omdsetkeys{assig}{#1}% collect the keys and correct them from the outside
+\@ifundefined{incl@assig@title}{}{\def\assig@title{\incl@assig@title}}
+\@ifundefined{incl@assig@type}{}{\def\assig@type{\incl@assig@type}}
+\@ifundefined{incl@assig@num}{}{\def\assig@num{\incl@assig@num}}
+\@ifundefined{incl@assig@due}{}{\def\assig@due{\incl@assig@due}}
+\@ifundefined{incl@assig@given}{}{\def\assig@given{\incl@assig@given}}
+\@ifundefined{assig@num}{\stepcounter{section}}%
+{\setcounter{section}{\assig@num}\setcounter{problem}{0}}
+\ifmultiple%
+\section*{\Assig@Type~\arabic{section}:~\Assig@Title\given@due{\\(})}
+ \addcontentsline{toc}{section}{\Assig@Type~{\arabic{section}}:~\Assig@Title}
+\else
+\begin{center}
+\Large\Course@Title\\
+{\bf{\Assig@Type}~{\arabic{section}}:~\Assig@Title\strut\\\large{\given@due()}}
+\end{center}
+\fi%ifmultiple
+}{}
+%</package>
+% \end{macrocode}
+%
+% \begin{macrocode}
+%<*ltxml>
+DefEnvironment('{assignment} OptionalKeyVals:assig',
+ "<omdoc:omgroup ?&KeyVal(#1,'id')(xml:id='&KeyVal(#1,'id')')() "
+ . "assig:dummy='for the namespace'"
+ . "?#locator(stex:srcref='#locator')()>"
+ . "<omdoc:metadata ?#locator(stex:srcref='#locator')()>"
+ . "<dc:title ?#locator(stex:srcref='#locator')()>"
+ . "Assignment ?&KeyVal(#1,'num')(&KeyVal(#1,'num').)()"
+ . "?&KeyVal(#1,'title')((&KeyVal(#1,'title')))"
+ . "</dc:title>"
+ . "?&KeyVal(#1,'given')(<omdoc:meta property='assig:given'>&KeyVal(#1,'given')</omdoc:meta>)()"
+ . "?&KeyVal(#1,'due')(<omdoc:meta property='assig:due'>&KeyVal(#1,'due')</omdoc:meta>)()"
+ . "?&KeyVal(#1,'pts')(<omdoc:meta property='assig:pts'>&KeyVal(#1,'pts')</omdoc:meta>)()"
+ . "</omdoc:metadata>"
+ . "#body"
+ ."</omdoc:omgroup>\n");
+%</ltxml>
+% \end{macrocode}
+% \end{environment}
+%
+% \subsection{Including Assignments}
+%
+% The next command is essentially a glorified |\include| statement, it just sets some
+% internal macros first that overwrite the local points,
+%
+% \begin{macrocode}
+%<*package>
+\define@key{incl@assig}{number}{\def\incl@assig@num{#1}}
+\define@key{incl@assig}{title}{\def\incl@assig@title{#1}}
+\define@key{incl@assig}{type}{\def\incl@assig@type{#1}}
+\define@key{incl@assig}{given}{\def\incl@assig@given{#1}}
+\define@key{incl@assig}{due}{\def\incl@assig@due{#1}}
+\newcommand{\includeassignment}[2][]{\bgroup\setkeys{incl@assig}{#1}\include{#2}\egroup}
+%</package>
+%<*ltxml>
+DefMacro('\includeassignment [] {}','\input{#2}');
+%</ltxml>
+% \end{macrocode}
+%
+% \begin{macrocode}
+%<*package>
+\def\CourseTitle#1{\gdef\Course@Title{#1}}
+%</package>
+%<*ltxml>
+DefConstructor('\CourseTitle{}','');

+%
+% \subsection{Typesetting Exams}
+%
+% \begin{macrocode}

+msplit
+"Module Split"
+
+Usage:
+ msplit <input filename> [options]
+
+Options:
+ --output <filename> filename of new main .tex file; default stdout
+ --path <path> path where to write the module files;
+ --header <filename> filename of header file to be included in all new .tex files
+ --verbose verbose on
+ --stop stop when \end{document} is found, not at EOF
+ --help show help screen
+
+
+NOTE: All options '--xoption' can be replaced by '-x' as long as there is only one option starting with 'x'
+
+This program splits the .tex file given at input into:
+ one main .tex file, that includes
+ more .tex files, each containing one module
+
+The name of the new main .tex file is specified by output option. The path to the inputted
+files can be specified by path. The name of one generated input file is "name of the
+module it contains".tex Running on one already split file will just make a copy. Example
+usage: ./msplit slides.tex -o sl.tex -p ./modules -s
+
+Interpretation: "Split the file slides.tex; wite the new main file as sl.tex and the
+inputted files should be placed in ./modules; if path does not exist, it is automatically
+created; stop when (uncommented) \end{document} is found."
+
+
+
+rf
+"Reuse Factor"
+
+Usage:
+ rf [options]
+
+Options:
+ --input <filename> .tex input file. stdin by default
+ --stop stop when \end{document} is found, not at EOF
+ --verbose verbose on
+ --help show help screen
+
+
+This program computes the reuse factor for the .tex document given at input. This number
+represents the ratio of latex processed lines of code to actual lines contained in file
+given at input. This number will always be 1 for files that have no \input or \include.
+
+Example usage:
+./rf -v -i slides.tex
+Interpretation: "Compute the reuse factor of slides.tex and show all processed files(verbose mode)."
+
+
+
+sgraph
+"Slides graph [representation]"
+
+Usage:
+ sgraph [options]
+
+Options:
+ --input <filename> .tex input file; stdin by default
+ --output <filename> output file; out.dot by default
+ --format <ps|png|jpg|...> output format; .ps by default; for available formats, see dot --help
+ --nodot do not generate .dot file, just target format
+ --root <string> the 'root' of the graph. (name of course)
+ --theory <string> generate a subgraph for the theory
+ --sliderange <begin:end> only look at the given slide range; (2:16 for example)
+ --stop stop reading data when \end{document} is found, not at EOF
+ --verbose verbose on
+ --help show help screen
+
+This program generates a .dot file readable by graphviz, containing a graph of the module
+usage in the .tex file given at input, optionally looking at a specific theory and/or
+slide range; it also adds a dummy 'root' for the graph, so one can see where everything
+starts. It then converts the .dot file to a given format (.ps by default) using graphviz
+and optionally deletes the intermediary .dot file.
+
+Example usage:
+./sgraph -i slides.tex -o graph -f ps -n -t TCN --sliderange 20:10000 -r GenCS -v
+
+Interpretation: "Generate the graph of slides.tex in .ps format, write it in graph.ps, do
+not keep the .dot file; include only the part needed for the theory 'TCN' and in the slide
+range 20 to 10000; use as root for the graph the string 'GenCS' and show all processed
+files."
+
+
+sms
+??
+
+Usage:
+ sms [options]
+
+Options:
+ --input <filename> .tex file to split; default stdin
+ --verbose verbose on
+ --stop stop when \end{document} is found, not at EOF
+ --help show help screen
+
+Generate .sms file from .tex file given at input; .sms files contain only the modules and
+the macros defined within, no other text.
+
+Example usage:
+./sms -i slides.tex -s
+
+Interpretation: "Generate the slides.sms file for slides.tex; Stop when \end{document} is found."
+
+
+
+
+bms
+"Build Module Structure"
+
+Usage:
+ bms [options]
+
+Options:
+ --input <filename> .tex file to read from
+ --graph <filename> if mentioned, produce the suggested module structure as
+ a graphviz digraph (.dot file)
+ --path <pathname> if mentioned, produce same input file/s (including
+ dependencies) in specified path with suggested
+ module structure.
+ --output <filename> the new name of the main .tex file in specified path
+ --root <string> if mentioned, a father module is included, so that all
+ other modules descend from it. generally the course name
+ --stop stop when \end{document} is found; default is to go on
+ --definitions show a list of all definitions
+ --verbose verbose on
+ --help show help screen
+
+
+This program has the purpose of computing a default module structure, such that a module
+uses another module if and only if it needs that module and does not need another
+descendant of it. First, the prgram reads all necessary data from the input .tex file,
+computes the minimal strictly required module usage structure, and writes it as a graphviz
+digraph, and/or writes a copy of the input .tex file (and maybe inputted files by the .tex
+file) with the new module structure in the given path. All paths are created if not
+existing.
+
+Example usage:
+./bms -i slides.tex -s -g - | dot -Tps > out.ps; ggv out.ps
+./bms -i slides.tex -g out.dot -p ./new
+
+Interpretation: "Build default module structure for slides.tex and write it to out.dot;
+also use the obtained module structure and copy the input file to given path with changed
+module usage."

+
+Options:
+
+ --path XXX specify the value of \XXX (some snippath) in case it is
+ = somePath not defined in the processed .tex file
+ --defpath XXX specify which \XXX (snippath definitions) to look for
+ --graph <filename> if mentioned, produce the suggested module structure as
+ a graphviz digraph. (.dot file)
+ --opath <pathname> if mentioned, produce same input file/s (including
+ dependencies) in specified path with suggested
+ module structure.
+ --output <name> the new name of the main .tex file in specified path.
+ --root <name> if mentioned, a father module is included, so that all
+ other modules descend from it. generally the course name.
+ --stop stop when \end{document} is found; default is to go on.
+ --definitions show a list of all definitions.
+ --modules show a list of all modules.
+ --verbose verbose on.
+ --help this screen.
+
+
+ This program has the purpose of computing a default module structure, according
+to actual necessities.
+ Example:
+ ./bms -i slides.tex -g out.dot
+ ./bms -i slides.tex -s -g - | dot -Tps > out.ps; ggv out.ps

+% \begin{abstract}
+% The |cmathml| package is part of the {\stex} collection, a version of {\TeX/\LaTeX}
+% that allows to markup {\TeX/\LaTeX} documents semantically without leaving the
+% document format, essentially turning {\TeX/\LaTeX} into a document format for
+% mathematical knowledge management (MKM).
+%
+% This package provides a collection of semantic macros for content {\mathml} and their
+% {\latexml} bindings. These macros form the basis of a naive translation from
+% semantically preloaded {\LaTeX} formulae into the content {\mathml} formulae via the
+% {\latexml} system.

+%\section{Introduction}\label{sec:intro}
+%
+% This document describes the collection of semantic macros for content {\mathml} and
+% their {\latexml} bindings. These macros can be used to mark up mathematical formulae,
+% exposing their functional/logical structure. This structure can be used by MKM systems
+% for added-value services, either directly from the {\sTeX} sources, or after
+% translation. Even though it is part of the {\stex} collection, it can be used
+% independently. Note that this documentation of the package presupposes the discussion of
+% the {\stex} collection to be self-contained.
+%
+% \subsection{Encoding Content {\mathml} in {\TeX/\LaTeX}}\label{sec:encoding}
+%
+% The |cmathml| packge presented here addresses part of transformation problem: representing
+% mathematical formulae in the {\LaTeX} workflow, so that content {\mathml} representations
+% can be derived from them. The underlying problem is that run-of-the-mill {\TeX/\LaTeX}
+% only specifies the presentation (i.e. what formulae look like) and not their content
+% (their functional structure). Unfortunately, there are no good methods (yet) to infer the
+% latter from the former, but there are ways to get presentation from content.
+%
+% The solution to this problem is to dump the extra work on the author (after all she knows
+% what she is talking about) and give them the chance to specify the intended structure. The
+% markup infrastructure supplied by the |cmathml| package lets the author do this without
+% changing the visual appearance, so that the {\LaTeX} workflow is not disrupted.
+%
+% To use these |cmathml| macros in a {\LaTeX} document, you will have to include the
+% |cmathml| package using |\usepackage{cmathml}| somewhere in the document preamble. Then
+% you can use the macros
+% \begin{verbatim}
+% $\Ceq{\Cexp{\Ctimes{\Cimaginaryi,\Cpi}},\Cuminus{\Ccn{1}}}$
+% \end{verbatim}
+% which will result in $e^{i\pi}=-1$ when the document is formatted in {\LaTeX}. If the
+% document is converted to {\xml} using the {\latexml} conversion tool, then the result
+% will be content {\mathml} representation:
+%
+%\begin{exfig}
+% \begin{verbatim}
+% <math xmlns="http://www.w3.org/1998/Math/MathML">
+% <apply>
+% <eq/>
+% <apply>
+% <exp/>
+% <apply><times><imaginaryi/><pi/></times></apply>
+% </apply>
+% <apply><minus/><cn>1</cn></apply>
+% </apply>
+% </math>
+% \end{verbatim}\vspace*{-.6cm}
+% \caption{Content {\mathml} Form of $e^{i\pi}=-1$}\label{fig:cmathml-eip}
+% \end{exfig}
+%
+% \subsection{Changing the {\TeX/\LaTeX} Presentation}\label{sec:changing}
+%
+% It is possible to change the default presentation (i.e. the result under {\LaTeX}
+% formatting): The semantic macros only function as interface control sequences, which
+% call an internal macro that does the actual presentation. Thus we simply have to
+% redefine the internal macro to change the presentation. This is possible locally or
+% globally in the following way:
+% \begin{verbatim}
+% \makeatletter
+% \gdef\CMathML@exp#1{exp(#1)}
+% \def\CMathML@pi{\varpi}
+% \makeatother
+% \end{verbatim}
+%
+% The first line is needed to lift the {\LaTeX} redefinition protection for internal
+% macros (those that contain the $\snippet{\@}$ character), and the last line restores it
+% for the rest of the document. The second line has a {\em{global}} (i.e. the presentation
+% will be changed from this point on to the end of the document.) redefinition of the
+% presentation of the exponential function in the {\LaTeX} output. The third line has a
+% {\em{local}} redefinition of the presentation (i.e. in the local group induced by
+% {\LaTeX}'s $\snippet{begin}/\snippet{end}$ grouping or by {\TeX}'s grouping induced by
+% curly braces). Note that the argument structure has to be respected by the presentation
+% redefinitions. Given the redefinitions above, our equation above would come out as
+% $exp(i\varpi)=-1$.
+%
+% \subsection{The Future: Heuristic Parsing}\label{sec:future}
+%
+% The current implementation of content {\mathml} transformation from {\LaTeX} to
+% {\mathml} lays a heavy burden on the content author: the {\LaTeX} source must be
+% semantically preloaded --- the structure of the formulae must be fully annotated. In our
+% example above, we had to write {|\Ceq{A,B}|} instead of the more conventional (and more
+% legible) {|A=B|}.\ednote{come up with a good mixed example}
+%
+% The reason for this is that this keeps the transformation to content {\mathml} very
+% simple, predictable and robust at the expense of authoring convenience. The
+% implementation described in this module should be considered as a first step and
+% fallback solution only. Future versions of the $\latexml$ tool will feature more
+% intelligent solutions for determining the implicit structure of more conventional
+% mathematical notations (and {\LaTeX} representations), so that writing content {\mathml}
+% via {\LaTeX} will become less tedious.
+%
+% However, such more advanced techniques usually rely on linguistic, structural, and
+% semantic information about the mathematical objects and their preferred
+% representations. They tend to be less predictable to casual users and may lead to
+% semantically unexpected results.\ednote{talk about sTeX and extensibility in
+% MathML/OpenMath/OMDoc}
+%
+% \newpage
+% \section{The User Interface}\label{sec:modules}
+%
+% We will now tabulate the semantic macros for the Content {\mathml} elements. We have
+% divided them into modules based on the sectional structure of the {\mathml}2
+% recommendation ($2^{nd}$ edition). Before we go into the specific elements one-by-one,
+% we will discuss some general properties of the |cmatml| macros and their {\latexml}
+% bindings.
+%
+% \subsection{Generalities of the Encoding}\label{sec:generalities}
+%
+% The semantic macros provided by the |cmatml| package differ mainly in the way they treat
+% their arguments. The simplest case are those for constants~\ref{sec:constants} that do
+% not take any. Others take one, two, three, or even four arguments, which have to be
+% {\TeX} tokens or have to be wrapped in curly braces. For operators that are associative
+% {\twin{associative}{operator}} like addition the argument sequence is provided as a
+% single {\TeX} argument (wrapped in curly braces) that contains a comma-separated
+% sequence of arguments (wrapped in curly braces where necessary).
+%
+% \DescribeMacro{\Capply} The current setup of the |cmathml| infrastructure minimizes the
+% need of specifying the {\mathml} {\element{apply}} element, since the macros are all in
+% applied form: As we have seen in the example in the Introduction~\ref{sec:intro}, a
+% macro call like {|\Cexp{A}|} corresponds to the application of the exponential function
+% to some object, so the necessary {\element{apply}} elements in the {\mathml}
+% representation are implicit in the {\LaTeX} formulation and are thus added by the
+% transformation. Of course this only works, if the function is a content {\mathml}
+% element. Often, in mathematics we will have situations, where the function is a variable
+% (or ``arbitrary but fixed'') function. Then the formula $f(x)$ represented as |$f(x)$|
+% in {\TeX} could (and sometimes will) be misunderstood by the Math parser as $f\cdot x$,
+% i.e. a product of the number $f$ with the number $x$, where $x$ has brackets for some
+% reason. In this case, we can disambiguate by using |\Capply{f}x|, which will also format
+% as $f(x)$.\ednote{what about $n$-ary functions?}
+%
+% By the same token, we do not need to represent the qualifier elements
+% {\element{condition}} and {\element{domainofapplication}}\footnote{We do not support the
+% {\element{fn}} element as it is deprecated in {\mathml}2 and the {\element{declare}}
+% and {\element{sep}} elements, since their semantic status is unclear (to the author,
+% if you feel it is needed, please gripe to me).}, for
+% {\twintoo{binding}{operator}s}. They are are folded into the special forms of the
+% semantic macros for the binding operators below (the ones with the {|Cond|} and {|DA|}
+% endings):
+%
+% For operators that are {\index*{associative}}, {\index*{commutative}}, and
+% {\index*{idempotent}} ({\index*{ACI}} i.e. {\index*{bracketing}},
+% order\twin{argument}{order}, and {\index*{multiplicity}} of arguments does not matter)
+% {\mathml} supplies the a special form of application as a binding operator (often called
+% the corresponding ``{\twintoo{big}{operator}})'', which ranges over a whole set of
+% arguments. For instance for the ACI operator $\cup$ for set union has the ``big''
+% operator for unions over collections of sets e.g. used in the power set
+% $\bigcup_{S\subseteq T}S$ of a set $T$. In some cases, the ``big'' operators are
+% provided independently by {\mathml}, e.g. the ACI addition operator has the sum operator
+% as a corresponding ``big operator'': $\sum_{x\in\Cnaturalnumbers}{x^i}$ is the sum of
+% the powers of $x$ for all natural numbers. Where they are not, we will supply extra
+% macros in the |cmathml| package, e.g. the |\CUnion| macro as the big operator for
+% |\Cunion|.
+%
+% Finally, some of the binding operators have multiple content models flagged by the
+% existence of various modifier elements. In these cases, we have provided different
+% semantic macros for the different cases.
+%
+% \subsection{The Token Elements}\label{sec:tokens}
+%
+% The {\mathml} token elements are very simple containers that wrap some presentation
+% {\mathml} text. The {\element{csymbol}} element is the extension element in
+% {\mathml}. It's content is the presentation of symbol, and it has a |definitionURL|
+% attribute that allows to specify a URI that specifies the semantics of the symbol. This
+% URL can be specified in an optional argument to the |\Ccsymbol| macro, in accordance
+% with usual mathematical practice, the |definitionURL| is not presented.
+% \DescribeMacro{\Ccn}\DescribeMacro{\Cci}\DescribeMacro{\Ccsymbol}
+% \begin{cmtab}
+% |\Ccn| & token & |\Ccn{t}| & $\Ccn{t}$\\\hline
+% |\Cci| & token & |\Cci{t}| & $\Cci{t}$\\\hline
+% |\Ccsymbol| & token, URI & |\Ccsymbol[http://w3.org]{t}|
+% & $\Ccsymbol[http://w3.org]{t}$\\\hline
+% \end{cmtab}
+% Like the |\Ccsymbol| macro, all other macros in the |camthml| package take an optional
+% argument\footnote{This may change into a KeyVaL argument in future versions of the
+% |cmathml| package.} for the |definitionURL| attribute in the corresponding {\mathml}
+% element.
+%
+%\newpage
+% \subsection{The Basic Content Elements}\label{sec:basic}
+%
+% The basic elements comprise various pieces of the {\mathml} infrastructure. Most of the
+% semantic macros in this section are relatively uneventful.
+%
+% \DescribeMacro{\Cinverse}\DescribeMacro{\Ccompose}\DescribeMacro{\Cident}
+% \DescribeMacro{\Cdomain}\DescribeMacro{\Ccodomain}\DescribeMacro{\Cimage}
+% \begin{cmtab}
+% |\Cinverse| & 1 & |\Cinverse{f}| & $\Cinverse{f}$\\\hline
+% |\Ccompose| & 1 & |\Ccompose{f,g,h}| & $\Ccompose{f,g,h}$\\\hline
+% |\Cident| & 0 & |\Cident| & $\Cident$\\\hline
+% |\Cdomain| & 1 & |\Cdomain{f}| & $\Cdomain{f}$\\\hline
+% |\Ccodomain| & 1 & |\Ccodomain{f}| & $\Ccodomain{f}$\\\hline
+% |\Cimage| & 1 & |\Cimage{f}| & $\Cimage{f}$\\\hline
+% \end{cmtab}
+%
+% \DescribeMacro{\Clambda}\DescribeMacro{\ClambdaDA}\DescribeMacro{\Crestrict} For the
+% {\element{lambda}} element, we only have the {\element{domainofapplication}} element, so
+% that we have three forms a $\lambda$-construct can have. The first one is the simple one
+% where the first element is a bound variable. The second one restricts the applicability
+% of the bound variable via a {\element{domainofapplication}} element, while the third one
+% does not have a bound variable, so it is just a function restriction
+% operator.\ednote{need ClambdaCond}
+%
+% \begin{cmtab}
+% |\Clambda| & 2 & |\Clambda{x,y}{A}| & $\Clambda{x,y}{A}$\\\hline
+% |\ClambdaDA| & 3 & |\ClambdaDA{x}{C}{A}| & $\ClambdaDA{x,y}{C}{A}$\\\hline
+% |\Crestrict| & 2 & |\Crestrict{f}{S}| & $\Crestrict{f}{S}$\\\hline
+% \end{cmtab}
+%
+% \DescribeMacro{ccinterval}\DescribeMacro{cointerval}
+% \DescribeMacro{ocinterval}\DescribeMacro{oointerval}
+% The {\element{interval}} constructor actually represents four types of intervals in
+% {\mathml}. Therefore we have four semantic macros, one for each combination of open and
+% closed endings:
+% \begin{cmtab}
+% |\Cccinterval| & 2 & |\Cccinterval{1}{2}| & $\Cccinterval{1}{2}$\\\hline
+% |\Ccointerval| & 2 & |\Ccointerval{1}{2}| & $\Ccointerval{1}{2}$\\\hline
+% |\Cocinterval| & 2 & |\Cocinterval{1}{2}| & $\Cocinterval{1}{2}$\\\hline
+% |\Coointerval| & 2 & |\Coointerval{1}{2}| & $\Coointerval{1}{2}$\\\hline
+% \end{cmtab}
+%
+%\DescribeMacro{\Cpiecewise}\DescribeMacro{\Cpiece}\DescribeMacro{\Cotherwise}
+% The final set of semantic macros are concerned with piecewise definition of functions.
+% \begin{cmtab}
+% |\Cpiecewise| & 1 & see below & see below\\\hline
+% |\Cpiece| & 2 & |\Cpiece{A}{B}| & $\begin{array}{ll}\Cpiece{A}{B}\end{array}$\\\hline
+% |\Cotherwise| & 1 & |\Cotherwise{B}| & $\begin{array}{ll}\Cotherwise{1}\end{array}$\\\hline
+% \end{cmtab}
+%
+% For instance, we could define the abstract value function on the reals with the following
+% markup
+%
+% \begin{center}
+% \begin{tabular}{|l|l|}\hline
+% Semantic Markup & Formatted\\\hline
+% \begin{minipage}{8cm}\footnotesize
+% \begin{verbatim}
+% \Ceq{\Cabs{x},
+% \Cpiecewise{\Cpiece{\Cuminus{x}}{\Clt{x,0}}
+% \Cpiece{0}{\Ceq{x,0}}
+% \Cotherwise{x}}}
+% \end{verbatim}
+% \end{minipage} &
+% $\Ceq{\Cabs{x},\Cpiecewise{\Cpiece{\Cuminus{x}}{\Clt{x,0}}
+% \Cpiece{0}{\Ceq{x,0}}
+% \Cotherwise{x}}}$
+% \\\hline
+% \end{tabular}
+% \end{center}
+%
+% \newpage
+% \subsection{Elements for Arithmetic, Algebra, and Logic}\label{sec:arith}
+%
+% This section introduces the infrastructure for the basic arithmetic operators. The first
+% set is very simple
+%
+% \DescribeMacro{\Cquotient}\DescribeMacro{\Cfactorial}\DescribeMacro{\Cdivide}
+% \DescribeMacro{\Cminus}\DescribeMacro{\Cplus}\DescribeMacro{\Cpower}
+% \DescribeMacro{\Crem}\DescribeMacro{\Ctimes}\DescribeMacro{\Croot}
+% \begin{cmtab}
+% |\Cquotient| & 2 & |\Cquotient{1}{2}| & $\Cquotient{1}{2}$\\\hline
+% |\Cfactorial| & 1 & |\Cfactorial{7}| & $\Cfactorial{7}$\\\hline
+% |\Cdivide| & 2 & |\Cdivide{1}{2}| & $\Cdivide{1}{2}$\\\hline
+% |\Cminus| & 2 & |\Cminus{1}{2}| & $\Cminus{1}{2}$\\\hline
+% |\Cplus| & 1 & |\Cplus{1}| & $\Cplus{1}$\\\hline
+% |\Cpower| & 2 & |\Cpower{x}{2}| & $\Cpower{x}{2}$\\\hline
+% |\Crem| & 2 & |\Crem{7}{2}| & $\Crem{7}{2}$\\\hline
+% |\Ctimes| & 1 & |\Ctimes{1,2,3,4}| & $\Ctimes{1,2,3,4}$\\\hline
+% |\Croot| & 2 & |\Croot{3}{2}| & $\Croot{3}{2}$\\\hline
+% \end{cmtab}
+%
+% The second batch below is slightly more complicated, since they take a set of
+% arguments. In the |cmathml| package, we treat them like {\index*{associative}}
+% operators, i.e. they act on a single argument that contains a sequence of
+% comma-separated arguments\ednote{implement this in the latexml side}
+%
+% \DescribeMacro{\Cmax}\DescribeMacro{\Cmin}\DescribeMacro{\Cgcd}\DescribeMacro{\Clcm}
+% \begin{cmtab}
+% |\Cmax| & 1 & |\Cmax{1,3,6}| & $\Cmax{1,3,6}$\\\hline
+% |\Cmin| & 1 & |\Cmin{1,4,5}| & $\Cmin{1,4,7}$\\\hline
+% |\Cgcd| & 1 & |\Cgcd{7,3,5}| & $\Cgcd{7,3,5}$\\\hline
+% |\Clcm| & 1 & |\Clcm{3,5,4}| & $\Clcm{3,5,4}$\\\hline
+% \end{cmtab}
+%
+% The operators for the logical connectives are associative as well\ednote{maybe add some
+% precedences here.}. Here, conjunction, (exclusive) disjunction are $n$-ary associative
+% operators, therefore their semantic macro only has one {\TeX} argument which contains a
+% comma-separated list of subformulae.
+% \DescribeMacro{\Cand}\DescribeMacro{\Cor}\DescribeMacro{\Cxor}\DescribeMacro{\Cnot}
+% \DescribeMacro{\Cimplies}
+% \begin{cmtab}
+% |\Cand| & 1 & |\Cand{A,B,C}| & $\Cand{A,B,C}$\\\hline
+% |\Cor| & 1 & |\Cor{A,B,C}| & $\Cor{A,B,C}$\\\hline
+% |\Cxor| & 1 & |\Cxor{A,B,C}| & $\Cxor{A,B,C}$\\\hline
+% |\Cnot| & 1 & |\Cnot{A}| & $\Cnot{A}$\\\hline
+% |\Cimplies| & 2 & |\Cimplies{A}{B}| & $\Cimplies{A}{B}$\\\hline
+% \end{cmtab}
+%
+% The following are the corresponding big operators, where appropriate.
+% \DescribeMacro{\CAndDA}\DescribeMacro{\CAndCond}
+% \DescribeMacro{\COrDA}\DescribeMacro{\COrCond}
+% \DescribeMacro{\CXorDA}\DescribeMacro{\CXorCond}
+% \begin{cmtab}
+% |\CAndDA| & 2 & |\CAndDA\Cnaturalnumbers\phi| & $\CAndDA\Cnaturalnumbers\phi$\\\hline
+% |\CAndCond| & 3 & |\CAndCond{x}{\Cgt{x}5}{\psi(x)}|

+% The semantic macros for the quantifiers come in two forms: with- and without a condition
+% qualifier. In a restricted quantification of the form $\forall x,C:A$, the bound variable
+% $x$ ranges over all values, such that $C$ holds ($x$ will usually occur in the condition
+% $C$). In an unrestricted quantification of the form $\forall x:A$, the bound variable
+% ranges over all possible values for $x$.

+% \subsection{Elements for Calculus and Vector Calculus}\label{sec:calculus-vector-calculus}
+%
+% The elements for calculus and vector calculus have the most varied forms.
+%
+% The integrals come in four forms: the first one is just an indefinite integral over a
+% function, the second one specifies the bound variables, upper and lower limits. The
+% third one specifies a set instead of an interval, and finally the last specifies a
+% bound variable that ranges over a set specified by a condition.

+%
+% \DescribeMacro{\Cdiff}\DescribeMacro{\Cddiff} The differentiation operators are used in
+% the usual way: simple differentiation is represented by the |\Cdiff| macro which takes
+% the function to be differentiated as an argument, differentiation with the $d$-notation
+% is possible by the |\Cddiff|, which takes the bound variable\ednote{really only one?} as
+% the first argument and the function expression (in the bound variable) as a second
+% argument.
+%
+% \DescribeMacro{\Cpartialdiff} Partial Differentiation is specified by the
+% |\Cpartialdiff| macro. It takes the overall degree as the first argument (to leave it
+% out, just pass the empty argument). The second argument is the list of bound variables
+% (with their degrees; see below), and the last the function expression (in these bound
+% variables). \DescribeMacro{\Cdegree} To specify the respective degrees of
+% differentiation on the variables, we use the |\Cdegree| macro, which takes two arguments
+% (but no optional argument), the first one is the degree (a natural number) and the
+% second one takes the variable. Note that the overall degree has to be the sum of the
+% degrees of the bound variables.

+%
+% \DescribeMacro{\Climit}\DescribeMacro{\ClimitCond} For content {\mathml}, there are two
+% kinds of limit expressions: The simple one is specified by the |\Climit| macro, which
+% takes three arguments: the bound variable, the target, and the limit expression. If we
+% want to place additional conditions on the limit construction, then we use the
+% |\ClimitCond| macro, which takes three arguments as well, the first one is a sequence of
+% bound variables, the second one is the condition, and the third one is again the limit
+% expression.
+%
+% \DescribeMacro{\Ctendsto}\DescribeMacro{\CtendstoAbove}\DescribeMacro{\CtendstoBelow} If
+% we want to speak qualitatively about limit processes (e.g. in the condition of a
+% |\ClimitCond| expression), then can use the {\mathml} {\element{tendsto}} element, which
+% is represented by the |\Ctendsto| macro, wich takes two expressions arguments. In
+% {\mathml}, the {\element{tendsto}} element can be further specialized by an attribute to
+% indicate the direction from which a limit is approached. In the |cmathml| package, we
+% supply two additional (specialized) macros for that: |\CtendstoAbove| and
+% |\CtendstoBelow|.

+% \section{The Implementation}\label{sec:impl}
+%
+% In this file we document both the implementation of the |cmathml| package, as well as
+% the corresponding {\latexml} bindings. This keeps similar items close to each other,
+% even though they eventually go into differing files and helps promote consistency. We
+% specify which code fragment goes into which file by the {\xml}-like grouping commands:
+% The code between {\textsf{$\langle$*sty$\rangle$}} and {\textsf{$\langle$/sty$\rangle$}}
+% goes into the package file |cmathml.sty|, and the code between
+% {\textsf{$\langle$*ltxml$\rangle$}} and {\textsf{$\langle$/ltxml$\rangle$}} goes into
+% |cmathml.ltxml|
+%
+% \subsection{Initialization and auxiliary functions}\label{sec:impl:init}
+%
+% We first make sure that the {\sTeX} |presentation| package is loaded.
+% \begin{macrocode}
+%<*sty|styx>
+\RequirePackage{presentation}
+%</sty|styx>
+% \end{macrocode}
+%
+% Before we start im plementing the {\mathml} macros, we will need to set up the packages
+% for perl in the {\latexml} bindings file.
+% \begin{macrocode}
+%<*ltxml|ltxmlx>
+# -*- CPERL -*-
+package LaTeXML::Package::Pool;
+use strict;
+use LaTeXML::Package;
+use LaTeXML::Document;
+RequirePackage('LaTeX');
+%</ltxml|ltxmlx>
+% \end{macrocode}
+%
+% The next step is to itroduce two auxiliary functions, they are needed to work with
+% $n$-ary function elements. The first one removes arbitrary tokens from a list, and the
+% specializes that to commas. In particular |remove_tokens_from_list($List, $pattern, $math)|
+% returns a new |List| (or |MathList| if |$math| is true)
+% with all the tokens in |$List| except the ones which follow
+% the pattern |$pattern|.
+%
+% \begin{macrocode}
+%<*ltxml>
+sub remove_tokens_from_list {
+ my ($list, $pattern, $math) = @_;
+ if (ref $list) {
+ my @toks = $list->unlist;
+ @toks = grep($_->toString !~ /$pattern/, @toks);
+ ($math ? (LaTeXML::MathList->new(@toks)) : (LaTeXML::List)->new(@toks)); }
+ else { undef; } }
+
+sub remove_math_commas {
+ my ($whatsit, $argno) = @_;
+ my @args = $whatsit ? $whatsit->getArgs() : undef;
+ $argno--;
+ if ($args[$argno]) {
+ $args[$argno] = remove_tokens_from_list($args[$argno], ',', 1);
+ $whatsit->setArgs(@args);
+ }
+ return;
+}
+%</ltxml>
+% \end{macrocode}
+%
+% The structural macros are rather simple:
+%
+% \begin{macrocode}
+%<*sty>
+\newcommand{\Capply}[3][]{#2(#3)}
+%</sty>
+%<*ltxml>
+DefConstructor('\Capply [] {} {}',
+ "<ltx:XMApp ?#1(definitionURL='#1')()>#2 #3</ltx:XMApp>");

+% \begin{abstract}
+% We present {\cnxlatex}, a collection of {\LaTeX} macros that allow to write
+% {\connexions} modules without leaving the {\LaTeX} workflow. Modules are authored in
+% {\cnxlatex} using only a text editor, transformed to PDF and proofread as usual. In
+% particular, the {\LaTeX} workflow is independent of having access to the {\connexions}
+% system, which makes {\cnxlatex} attractive for the initial version of single-author
+% modules.
+%
+% For publication, {\cnxlatex} modules are transformed to {\cnxml} via the {\latexml}
+% translator and can be uploaded to the {\connexions} system.

+%\section{Introduction}
+%
+% The Connexions project is a\ednote{continue; copy from somewhere...}
+%
+% The {\cnxml} format --- in particular the embedded content {\mathml} --- is hard to write
+% by hand, so we provide a set of environments that allow to embed the {\cnxml} document
+% model into {\LaTeX}.
+%
+%\section{The User Interface}
+%
+% This document is not a manual for the Connexions XML encoding, or a practical guide how
+% to write Connexions modules. We only document the {\LaTeX} bindings for {\cnxml} and will
+% presuppose experience with the format or familiarity with\ednote{cite the relevant stuff
+% here}. Note that formatting {\cnxlatex} documents with the {\LaTeX} formatter does
+% little to enforce the restrictions imposed by the {\cnxml} document model. You will need to
+% run the {\latexml} converter for that (it includes DTD validation) and any CNX-specific
+% quality assurance tools after that. \ednote{talk about Content {\mathml} and cmathml.sty
+% somewhere}
+%
+% The {\cnxlatex} class makes heavy use of the |KeyVal| package, which is part of your
+% {\LaTeX} distribution. This allows to add optional information to {\LaTeX} macros in the
+% form of key-value pairs: A macro |\foo| that takes a KeyVal argument and a regular one,
+% so a call might look like |\foo{bar}| (no KeyVal information given) or
+% |\foo[key1=val1,...,keyn=valn]{bar}|, where |key1|,\dots,|keyn| are predefined keywords
+% and values are {\LaTeX} token sequences that do not contain comma characters (though
+% they may contain blank characters). If a value needs to contain commas, then it must be
+% enclosed in curly braces, as in |\foo[args={a,comma,separated,list}]|. Note that the
+% order the key/value pairs appear in a KeyVal Argument is immaterial.
+%
+% \subsection{Document Structure}
+%
+% \begin{exfig}
+%\begin{verbatim}
+% \documentclass{cnx}
+% \begin{document}
+% \begin{cnxmodule}[name=Hello World,id=m4711]
+% \begin{ccontent}
+% \begin{cpara}[id=p01] Hello World\end{cpara}
+% \end{ccontent}
+% \end{cnxmodule}
+% \end{document}
+% \end{verbatim}
+% \caption{A Minimal {\cnxlatex} Document}\label{fig:minimal}
+%\end{exfig}
+%
+% The first set of {\cnxlatex} environments concern the top-level structure of the
+% modules. The minimal Connexions document in {\LaTeX} can be seen in
+% Figure~\ref{fig:minimal}: we still need the {\LaTeX} document environment, then
+% \DescribeEnv{cnxmodule}
+% the |cnxmodule| environment contains the module-specific information as a KeyVal
+% argument with the two keys: |id| for the module identifier supplied by the
+% {\connexions} system) and |name| for the title of the module.
+%
+% \DescribeEnv{ccontent}
+% The |content| environment delineates the module content from the metadata (see
+% Section~\ref{sec:metadata}). It is needed to make the conversion to {\cnxml} simpler.
+%
+% \DescribeEnv{c*section}
+% {\cnxml} knows three levels of sectioning, so the {\cnxlatex} class supplies three as
+% well: |csection|, |csubsection| and |csubsubsection|. In contrast to regular
+% {\LaTeX}, these are environments to keep the tight connection between the
+% formats. These environments take an optional KeyVal argument with key |id| for the
+% identifier and a regular argument for the title of the section (to be transformed into
+% the {\cnxml} {\element{name}} element).
+%
+% \DescribeEnv{cpara, cnote}
+% The lowest levels of the document structure are given by paragraphs and notes. The
+% |cpara| and |cnote| environment take a KeyVal argument with the |id| key for
+% identification, the latter also allows a |type| key for the note type (an unspecified
+% string\ednote{what are good values?}).
+%
+%
+% \subsection{Mathematics}
+%
+% Mathematical formulae are integrated into text via the {\LaTeX} math mode, i.e. wrapped
+% in |$| characters or between |\(| and |\)| for inline mathematics and wrapped in |$$| or
+% between |\[| and |\]| for display-style math. Note that {\cnxml} expects Content
+% {\mathml} as the representation format for mathematical formulae, while run-of-the-mill
+% {\LaTeX} only specifies the presentation (i.e. the two-dimensional layout of
+% formulae). The {\latexml} converter can usually figure out some of the content {\mathml}
+% from regular {\LaTeX}, in other cases, the author has to specify it e.g. using the
+% infrastructure supplied by the |cmathml| package.
+%
+% \DescribeEnv{cequation}
+% For numbered equations, {\cnxml} supplies the {\element{equation}} element, for which
+% {\cnxlatex} provides the |cequation| environment. This environment takes a KeyVal
+% argument with the |id| key for the (required) identifier.
+%
+%
+% \subsection{Statements}
+%
+% {\cnxml} provides special elements that make various types of claims; we
+% collectively call them statements.
+%
+% \DescribeEnv{cexample}
+% The |cexample| environment and |definition| elements take a KeyVal argument with key
+% |id| for identification.
+%
+%
+% \DescribeEnv{crule, statement, proof}
+% In {\cnxml}, the {\element{rule}} element is used to represent a general assertion
+% about the state of the world. The {\cnxlatex} |rule|\ednote{we have called this
+% ``crule'', since ``rule'' is already used by {\TeX}.} environment is its {\cnxlatex}
+% counterpart. It takes a KeyVal attribute with the keys |id| for identification, |type|
+% to specify the type of the assertion (e.g. ``Theorem'', ``Lemma'' or ``Conjecture''),
+% and |name|, if the assertion has a title. The body of the |crule| environment contains
+% the statement of assertion in the |statement| environment and (optionally) a proof in
+% the |proof| environment. Both take a KeyVal argument with an |id| key for
+% identification.
+%
+%\begin{exfig}
+%\begin{verbatim}
+% \begin{crule}[id=prop1,type=Proposition]
+% \begin{statement}[id=prop1s]
+% Sample statement
+% \end{statement}
+% \begin{proof}[id=prop1p]
+% Your favourite proof
+% \end{proof}
+% \end{crule}
+% \end{verbatim}
+% \caption{A Basic crule Example}\label{fig:crule}
+%\end{exfig}
+%
+% \DescribeEnv{definition, cmeaning} A definition defines a new technical term or concept
+% for later use. The |definition| environment takes a KeyVal argument with the keys |id|
+% for identification and |term| for the concept (definiendum) defined in this form. The
+% definition text is given in the |cmeaning| environment\footnote{we have called this
+% |cmeaning|, since |meaning| is already taken by {\TeX}}, which takes a KeyVal argument
+% with key |id| for identification. After the |cmeaning| environment, a |definition| can
+% contain arbitrarily many |cexample|s.
+%
+%\begin{exfig}
+%\begin{verbatim}
+% \begin{definition}{term=term-to-be-defined, id=termi-def]
+% \begin{cmeaning}[id=termi-meaning]
+% {\term{Term-to-be-defined}} is defined as: Sample meaning
+% \end{cmeaning}
+% \end{definition}
+%\end{verbatim}
+% \caption{A Basic {\tt{definition}} and {\tt{cmeaning}} Example}\label{fig:def-cmean}
+%\end{exfig}
+%
+% \subsection{Connexions: Links and Cross-References}
+%
+% As the name {\connexions} already suggests, links and cross-references are very
+% important for {\connexions} modules. {\cnxml} provides three kinds of them. Module
+% links, hyperlinks, and concept references.
+%
+% \DescribeMacro{cnxn}
+% Module links are specified by the |\cnxn| macro, which takes a keyval argument with
+% the keys |document|, |target|, and |strength|. The |document| key allows to specify
+% the module identifier of the desired module in the repository, if it is empty, then
+% the current module is intended. The |target| key allows to specify the document
+% fragment. Its value is the respective identifier (given by its |id| attribute in
+% {\cnxml} or the |id| key of the corresponding environment in {\cnxlatex}). Finally,
+% the |strength| key allows to specify the relevance of the link.
+%
+% The regular argument of the |\cnxn| macro is used to supply the link text.
+%
+%
+% \DescribeMacro{link}
+% Hyperlinks can be specified by the |\link| macro in {\cnxlatex}. It takes a KeyVal
+% argument with the key |src| to specify the URL of the link. The regular argument of
+% the |\link| macro is used to supply the link text.
+%
+%
+% \DescribeMacro{term}
+% The |\term| marco can be used to specify the\ednote{continue, pending Chuck's
+% investigation. }
+%
+%
+% \subsection{Metadata}\label{sec:metadata}
+%
+% Metadata is mostly managed by the system in {\connexions}, so we often do not need to
+% care about it. On the other hand, it influences the system, so if we have work on the
+% module extensively before converting it to {\cnxml}, it may be worth-wile specify some of
+% the data in advance.
+%
+% \begin{exfig}

+%
+% \DescribeEnv{metadata}
+% The |metadata| environment takes a KeyVal argument with the keys |version|, |created|,
+% and |revised| with the obvious meanings. The latter keys take ISO 8601 norm
+% representations for dates and times. Concretely, the format is
+% {\snippet{CCYY-MM-DDThh:mm:ss}} where ``{\snippet{CC}}'' represents the century,
+% ``{\snippet{YY}}'' the year, ``{\snippet{MM}}'' the month, and ``{\snippet{DD}}'' the
+% day, preceded by an optional leading ``{\snippet{-}}'' sign to indicate a negative
+% number. If the sign is omitted, ``{\snippet{+}}'' is assumed. The letter
+% ``{\snippet{T}}'' is the date/time separator and ``{\snippet{hh}}'',
+% ``{\snippet{mm}}'', ``{\snippet{ss}}'' represent hour, minutes, and seconds
+% respectively.
+%
+%
+% \DescribeEnv{authorlist, maintainerlist}
+% The lists of authors and maintainers can be specified in the |authorlist| and
+% |maintainerlist| environments, which take no arguments.
+%
+% \DescribeMacro{cnxauthor,maintainer}
+% The entries on this lists are specified by the |\cnxauthor| and |\maintainer|
+% macros. Which take a KeyVal argument specifying the individual. The |id| key is the
+% identifier for the person, the |honorific|, |firstname|, |other|, |surname|, and
+% |lineage| keys are used to specify the various name parts, and the |email| key is used
+% to specify the e-mail address of the person.
+%
+%
+% \DescribeEnv{keywordlist, keyword}
+% The keywords are specified with a list of |keyword| macros, which take the respective
+% keyword in their only argument, inside a |keyword| environment. Neither take any
+% KeyVal arguments.
+%
+%
+% \DescribeEnv{cnxabstract}
+% The abstract of a {\connexions} module is considered to be part of the metadata. It is
+% specified using the |cnxabstract| environment. It does not take any arguments.
+%
+%
+% \subsection{Exercises}
+%
+% \DescribeEnv{cexercise, cproblem, csolution}
+% An exercise or problem in {\connexions} is specified by the |cexercise| environment,
+% which takes an optional keyval argument with the keys |id| and |name|. It must contain
+% a |cproblem| environment for the problem statement and a (possibly) empty set of
+% |csolution| environments. Both of these take an optional keyval argument with the key
+% |id|.
+%
+% \subsection{Graphics, etc.}
+%
+% \DescribeMacro{cfigure} For graphics we will use the |cfigure|\ednote{probably better
+% call it {\tt{cgraphics}}} macro, which provides a non-floating environment for
+% including graphics into {\cnxml} files. |cfigure| takes three arguments first an
+% optional {\cnxml} keys, then the keys of the |graphicx| package in a regular argument
+% (leave that empty if you don't have any) and finally a path. So
+% \begin{center}
+% |\cfigure[id=foo,type=image/jpeg,caption=The first FOO]{width=7cm,height=2cm}{../images/foo}|
+% \end{center}
+% Would include a graphic from the file at the path |../images/foo|, equip this image with
+% a caption, and tell {\latexml} that\ednote{err, exactly what does it tell latexml?} the
+% original of the images has the MIME type |image/jpeg|.
+%

+%
+% \section{The Implementation}
+%
+% The |cnx| package generates to files: the {\LaTeX} package (all the code between
+% {\textsf{$\langle$*package$\rangle$}} and {\textsf{$\langle$/package$\rangle$}}) and the
+% {\latexml} bindings (between {\textsf{$\langle$*ltxml$\rangle$}} and
+% {\textsf{$\langle$/ltxml$\rangle$}}). We keep the corresponding code fragments together,
+% since the documentation applies to both of them and to prevent them from getting out of
+% sync.
+%
+% We first make sure that the |sref|~\ctancite{Kohlhase:sref} and |graphicx| packages are
+% loaded.
+% \begin{macrocode}
+%<*cls>
+\RequirePackage{sref}
+\RequirePackage{graphicx}
+% \end{macrocode}
+%
+% The next step is to declare (a few) class options that handle the paper size; this is
+% useful for printing.
+% \begin{macrocode}
+\DeclareOption{letterpaper}
+ {\setlength\paperheight {11in}%
+ \setlength\paperwidth {8.5in}}
+\DeclareOption{a4paper}
+ {\setlength\paperheight {297mm}%
+ \setlength\paperwidth {210mm}}
+\ExecuteOptions{letterpaper}
+\ProcessOptions
+% \end{macrocode}
+% Finally, we input all the usual size settings. There is no sense to use something else,
+% and we initialize the page numbering counter and tell it to output the numbers in arabic
+% numerals (otherwise label and reference do not work).
+% \begin{macrocode}
+\input{size10.clo}
+\pagenumbering{roman}
+%</cls>
+% \end{macrocode}
+% Now comes the equivalent for {\latexml}: this is something that we will have throughout
+% this document. Every part of the {\TeX/\LaTeX} implementation has a {\latexml}
+% equivalent. We keep them together to ensure that they do not get out of sync.
+% \begin{macrocode}
+%<*ltxml>
+# -*- CPERL -*-
+package LaTeXML::Package::Pool;
+use strict;
+use LaTeXML::Package;
+RequirePackage('omd');
+% \end{macrocode}
+% We set up the necessary namespaces, the first one is the default one for {\cnxml}
+% \begin{macrocode}
+RegisterNamespace('cnx'=>"http://cnx.rice.edu/cnxml");
+RegisterNamespace('md'=>"http://cnx.rice.edu/mdml/0.4");
+RegisterNamespace('bib'=>"http://bibtexml.sf.net/");
+RegisterNamespace('m'=>"http://www.w3.org/1998/Math/MathML");
+% \end{macrocode}
+% For {\latexml} we also have to set up the correct document type information. The first line
+% gives the root element. The second gives the public identifier for the CNX DTD, then we
+% have its URL, and finally the CNX namespace.
+% \begin{macrocode}
+DocType("cnx:document",
+ "-//CNX//DTD CNXML 0.5 plus LaTeXML//EN",
+ "../dtd/cnxml+ltxml.dtd",
+ '#default'=>"http://cnx.rice.edu/cnxml",
+ 'md'=>"http://cnx.rice.edu/mdml/0.4",
+ 'bib'=>"http://bibtexml.sf.net/",
+ 'm'=>"http://www.w3.org/1998/Math/MathML",
+ 'ltx'=>"http://dlmf.nist.gov/LaTeXML");
+% \end{macrocode}
+%
+% And finally, we need to set up the counters for itemization, since we are defining a
+% class file from scratch.\ednote{this will have to change, when Bruce updates to the next
+% version (0.6?)}
+%
+% \begin{macrocode}
+NewCounter('@itemizei', 'document', idprefix=>'I');
+NewCounter('@itemizeii', '@itemizei', idprefix=>'I');
+NewCounter('@itemizeiii', '@itemizeii', idprefix=>'I');
+NewCounter('@itemizeiv', '@itemizeiii',idprefix=>'I');
+NewCounter('@itemizev', '@itemizeiv', idprefix=>'I');
+NewCounter('@itemizevi', '@itemizev', idprefix=>'I');
+
+NewCounter('enumi', '@itemizei', idprefix=>'i');
+NewCounter('enumii', '@itemizeii', idprefix=>'i');
+NewCounter('enumiii','@itemizeiii', idprefix=>'i');
+NewCounter('enumiv', '@itemizeiv', idprefix=>'i');
+# A couple of more levels, since we use these for ID's!
+NewCounter('enumv', '@itemizev', idprefix=>'i');
+NewCounter('enumvi', '@itemizevi', idprefix=>'i');
+
+DefMacro('\theenumi', '\arabic{enumi}');
+DefMacro('\theenumii', '\alph{enumii}');
+DefMacro('\theenumiii', '\roman{enumiii}');
+DefMacro('\theenumiv', '\Alph{enumiv}');
+
+NewCounter('equation', 'document', idprefix=>'E');
+DefMacro('\theequation', '\arabic{equation}');
+DefMacro('\textwidth','16cm');
+% \end{macrocode}
+%
+% And another thing that is now needed:
+%
+% \begin{macrocode}
+Let('\thedocument@ID','\@empty');
+%</ltxml>
+% \end{macrocode}
+%
+% \subsection{Document Structure}
+%
+% Now, we start with the document structure markup. The |cnxmodule| environment does not
+% add anything to the {\LaTeX} output, it's attributes only show up in the {\xml}. There
+% we have a slight complication: we have to put an |id| attribute on the |document|
+% element in {\cnxml}, but we cannot redefine the |document| environment in
+% {\LaTeX}. Therefore we specify the information in the |cnxmodule| environment. This
+% means however that we have to put in on the |document| element when we are already past
+% this. The solution here is that when we parse the |cnxmodule| environement, we store the
+% value and put it on the |document| element when we leave the |document| environment
+% (thanks for Ioan Sucan for the code).
+%

+% \maketitle
+%
+% \begin{abstract}
+% We present a document class from which we can generate both course slides and course
+% notes in a transparent way. Furthermore, we present a set of {\latexml} bindings for
+% these, so that we can also generate {\omdoc}-based course materials, e.g. for
+% inclusion in the {\activemath} system.
+% \end{abstract}
+% \tableofcontents\newpage
+%\section{Introduction}
+% This Document class is derived from |beamer.cls|, specializes it with Jacobs stuff and
+% adds a notes version that is more suited to printing than the one supplied by
+% |beamer.cls|.
+%
+%\section{The User Interface}\label{sec:user}
+% \StopEventually{\newpage\PrintChanges}
+%
+%\section{The Implementation}\label{sec:impl}
+%
+%\subsection{Initialization and Class Options}\label{sec:impl:init}
+%
+% For the {\latexml} bindings, we make sure the right perl packages are loaded.
+%
+% \begin{macrocode}
+%<*ltxml>
+# -*- CPERL -*-

+use strict;
+use LaTeXML::Package;
+%</ltxml>
+% \end{macrocode}
+%
+% For {\LaTeX} we define some Package Options and switches for the |mikoslides| class and activate
+% them by passing them on to |beamer.cls| the appropriate packages.
+%
+% \begin{macrocode}
+%<*cls>
+\newif\ifnotes\notesfalse
+\newif\ifproblems\problemstrue
+\DeclareOption{notes}{\notestrue}
+\DeclareOption{slides}{\notesfalse}
+\DeclareOption{noproblems}{\problemsfalse}

+\ProcessOptions
+%</cls>
+%<*ltxml>
+RawTeX('\newif\ifnotes\notesfalse');
+RawTeX('\newif\ifproblems\problemsfalse');
+%</ltxml>
+% \end{macrocode}
+%
+% Depending on the options, we either load the |article|-based |omdoc| or the |beamer| class. In the first
+% case, we also have to make the |beamer|-specific things available to |article| via the
+% |beamerarticle| package. We use options to avoid loading theorem-like environments,
+% since we want to use our own from the $\sTeX$ packages.
+% \begin{macrocode}
+%<*cls>

+\newcounter{Hfootnote}
+\usetheme{Jacobs}
+\fi
+%</cls>
+%<*ltxml>
+LoadClass('omdoc');
+%</ltxml>
+% \end{macrocode}
+%
+% now, we load the remaining packages for both versions.
+%
+% \begin{macrocode}
+%<*cls>
+\RequirePackage{stex}
+\RequirePackage{latexml}
+\RequirePackage{amssymb}
+\RequirePackage{tikz}
+\usepgflibrary{shapes}\usetikzlibrary{arrows}

+%<*ltxml>
+RequirePackage('stex');
+RequirePackage('latexml');
+RequirePackage('amssymb');
+RequirePackage('graphicx');
+RequirePackage('tikz');
+RequirePackage('amsmath');
+%</ltxml>
+% \end{macrocode}
+% \begin{oldpart}{we do not seem to load this any more, what to do
+% there?}% The |etex.sty| package is needed in the {\LaTeX}, since it makes the extended the number
+% of internal registers of the |etex| program available for processing. These tend to run
+% out with {\sTeX} otherwise.
+% \end{oldpart}
+%
+% \subsection{Notes and Slides}\label{sec:impl:noteslides}
+%
+% We define the sizes of slides in the notes. Somehow, we cannot get by with the same
+% here.
+%
+% \begin{macrocode}
+%<*cls>
+\newcounter{slide}
+\newlength{\slidewidth}\setlength{\slidewidth}{13.5cm}
+\newlength{\slideheight}\setlength{\slideheight}{9cm}
+%</cls>
+%<*ltxml>
+DefRegister('\slidewidth' => Dimension('13.5cm'));
+DefRegister('\slideheight' => Dimension('9cm'));
+%</ltxml>
+% \end{macrocode}
+%
+% For course notes, we define the |note| environment to be a no-operation otherwise we declare the |note| environment as
+% a comment via the |comment| package.
+%
+% \begin{environment}{note}
+% \begin{macrocode}
+%<*cls>
+\ifnotes\renewenvironment{note}{}{}\else\excludecomment{note}\fi
+%</cls>
+%<*ltxml>
+DefEnvironment('{note}','#body');
+%</ltxml>
+% \end{macrocode}
+% \end{environment}
+%
+%
+% the next step is to set up the slide boxes in |article| mode. We set up sizes and
+% provide a box register for the frames and a counter for the slides.
+%
+% \begin{macrocode}
+%<*cls>
+\ifnotes
+\newlength{\slideframewidth}\setlength{\slideframewidth}{2pt}
+\newsavebox{\myframebox}
+%</cls>
+% \end{macrocode}
+%
+% \begin{environment}{frame}
+% For the |frame| environment we construct a |lrbox| in the |\myframebox| register that
+% we can later put into an |\fbox| so that it looks like a slide. Furthermore, we
+% redefine the |itenize| environment so that it looks more like the one in |beamer| with
+% |Jacobs| theme.
+% \begin{macrocode}
+%<*cls>
+\renewenvironment{frame}[1][]%
+{\stepcounter{slide}
+\def\itemize@level{outer}
+\def\itemize@outer{outer}
+\def\itemize@inner{inner}
+\renewenvironment{itemize}
+{\ifx\itemize@level\itemize@outer\def\itemize@label{$\rhd$}\fi
+ \ifx\itemize@level\itemize@inner\def\itemize@label{$\scriptstyle\rhd$}\fi
+ \begin{list}
+ {\itemize@label}
+ {\setlength{\labelsep}{.3em}\setlength{\labelwidth}{.5em}\setlength{\leftmargin}{1.5em}}
+ \edef\itemize@level{\itemize@inner}}
+{\end{list}}
+ \noindent\hfill\begin{lrbox}{\myframebox}
+ \begin{minipage}{\slidewidth}\sf}%
+ {\miko@slidelabel\end{minipage}\end{lrbox}%
+ \begin{center}\fbox{\usebox\myframebox}\end{center}\hfill}
+%</cls>
+%<*ltxml>
+DefEnvironment('{frame}[]',
+ "<omdoc:omgroup layout='slide' ?#locator(stex:srcref='#locator')()>"
+ . "#body\n"
+ ."</omdoc:omgroup>\n\n",
+ afterDigestBegin=>sub {
+ $_[1]->setProperty(theory=>LookupValue('current_module')); });
+%</ltxml>#$
+% \end{macrocode}
+% \end{environment}
+%
+% the next step is to set up the slide boxes in |article| mode.
+%
+% \begin{macrocode}
+%<*cls>
+\renewcommand{\frametitle}[1]{{\Large\bf\sf\color{blue}{#1}}}
+\fi
+\makeindex
+%</cls>
+%<*ltxml>
+DefConstructor('\frametitle{}',
+ "\n<omdoc:metadata ?#locator(stex:srcref='#locator')()><dc:title>#1</dc:title></omdoc:metadata>");
+%</ltxml>
+% \end{macrocode}
+%
+% We start by giving the {\latexml} binding for the |frame| environment from the |beamer|
+% class. The |note| environment is used to blend out text in the |slides| mode. It does
+% not have a counterpart in OMDoc.
+%
+% \begin{macrocode}
+%<*cls>
+\ifproblems\newenvironment{problems}{}{}\else\excludecomment{problems}\fi
+%</cls>
+%<*ltxml>
+DefEnvironment('{problems}','#body');
+%</ltxml>
+% \end{macrocode}
+%\ednote{subtitle is difficult to model in DC metadata. I guess that we want to collect
+%the subtitle into dc:title}
+%
+% \subsection{Header and Footer Lines}\label{sec:impl:headfootlines}
+%
+% Now, we set up the infrastructure for the footer line of the slides, we use boxes for
+% the logos, so that they are only loaded once, that considerably speeds up processing.
+% \begin{macrocode}
+%<*cls>
+\newlength{\slidelogoheight}
+\ifnotes\setlength{\slidelogoheight}{.4cm}\else\setlength{\slidelogoheight}{1cm}\fi
+\newsavebox{\slidelogo}\sbox{\slidelogo}{\includegraphics[height=\slidelogoheight]{jacobs-logo}}
+% \end{macrocode}
+%
+% Now, we set up the copyright and licensing, the copyright remains with the author, but
+% we use the Creative Commons Attribuition-ShareAlike license to strengthen den public
+% domain. Here the problem is that we want a hyperref on the CC logo, if hyperref is
+% loaded, and otherwise not. As hyperref is always loaded, we have to find out at the
+% beginning of the document whether it is, set up a switch, and later in the footer line
+% decide what to do.
+%
+% \begin{macrocode}
+\def\source{Michael Kohlhase}% customize locally
+\def\copyrightnotice{\footnotesize\copyright:\hspace{.3ex}{\source}}
+\newsavebox{\cclogo}\sbox{\cclogo}{\includegraphics[height=\slidelogoheight]{cc_somerights}}
+\newif\ifcchref\cchreffalse
+\AtBeginDocument{\@ifpackageloaded{hyperref}{\cchreftrue}{\cchreffalse}}
+\def\licensing{\ifcchref\href{http://creativecommons.org/licenses/by-sa/2.5/}{\usebox{\cclogo}}\else{\usebox{\cclogo}}\fi}
+% \end{macrocode}
+%
+% Now, we set up the slide label for the |article| mode\ednote{see that we can use the
+% themes for the slides some day. This is all fake.}
+%
+% \begin{macro}{\slidelabel}
+% \begin{macrocode}
+\newcommand{\miko@slidelabel}%

+{\licensing\hfill\copyrightnotice\hfill\arabic{slide}\hfill\usebox{\slidelogo}}}}
+%</cls>
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Colors and Highlighting}\label{sec:impl:highlighting}
+%
+% Now, we set up an infrastructure for highlighting phrases in slides. Note that we use
+% content-oriented macros for highlighting rather than directly using color markup.
+% The first thing to to is to adapt the green so that it is dark enough for most beamers
+% \begin{macrocode}
+%<*cls>
+\AtBeginDocument{\definecolor{green}{rgb}{0,.5,0}\definecolor{purple}{cmyk}{.3,1,0,.17}}
+% \end{macrocode}
+%
+% We customize the |\defemph|, |\notemph|, and |\stDMemph| macros with colors for the use
+% in the |statements| package. Furthermore we customize the |\@@lec| macro for the
+% appearance of line end comments in |\lec|.
+%
+% \begin{macrocode}
+\def\defemph#1{{\textcolor{magenta}{#1}}}
+\def\notemph#1{{\textcolor{magenta}{#1}}}
+\def\stDMemph#1{{\textcolor{blue}{#1}}}
+\def\@@lec#1{(\textcolor{green}{#1})}
+%</cls>
+%<*ltxml>
+#DefMacro('\defemph{}','{\textcolor{magenta}{#1}}');
+#DefMacro('\notemph{}','{\textcolor{magenta}{#1}}');
+%</ltxml>
+% \end{macrocode}
+%
+% I like to use the dangerous bend symbol for warnings, so we provide it here.
+% \begin{macrocode}
+%<*cls>
+\def\textwarning{\raisebox{-.05cm}{\includegraphics[width=1.2em]{dangerous-bend}}\xspace}
+%</cls>
+%<*ltxml>
+DefMacro('\textwarning',"");
+%</ltxml>
+% \end{macrocode}
+% Now, we specialize the slide environment that we have implemented above or inherited
+% from |seminar.cls| for some abbreviations, e.g. separator slides and title slides.
+% \begin{macrocode}
+%<*cls>
+\newenvironment{ttitle}{\begin{center}\LARGE\begin{tabular}{|c|}\hline}%
+ {\\\hline\end{tabular}\end{center}\vspace{1ex minus 1ex}}
+\newenvironment{ttitlejoint}[1]%

+\begin{center}\LARGE\begin{tabular}{c}\color{red}}%
+{\\\box\boxwith\end{tabular}\end{center}%
+\vspace{1ex minus 1ex}}
+%</cls>
+%<*ltxml>
+DefEnvironment('{titleslide}',"");
+DefEnvironment('{titleslide}',"<omdoc:omgroup ?#locator(stex:srcref='#locator')()>#body</omdoc:omgroup>");
+DefEnvironment('{ttitle}', "\n<Title>#body</Title>");
+%</ltxml>
+% \end{macrocode}
+%
+% \begin{macrocode}
+% Must be first command on slide to make positioning work.
+%<*cls>
+\newcommand{\putgraphicsat}[3]{%
+ \begin{picture}(0,0)\put(#1){\includegraphics[#2]{#3}}\end{picture}}
+\newcommand{\putat}[2]{%
+ \begin{picture}(0,0)\put(#1){#2}\end{picture}}
+%</cls>
+%<*ltxml>
+%</ltxml>
+% \end{macrocode}
+%
+% \subsection{Miscellaneous}
+%
+% Some shortcuts that use math symbols but are not mathematical at all; in particular,
+% they should not be translated by {\latexml}.
+%
+% \begin{macrocode}
+%<*cls>
+\newcommand\hateq{\ensuremath{\hat=}}
+\newcommand\textleadsto{\ensuremath{\leadsto}}
+%</cls>
+%<*ltxml>
+DefConstructor('\hateq',"=\x{03C2}");
+DefConstructor('\textleadsto',"=\x{219D}");
+%</ltxml>
+% \end{macrocode}
+%
+% We need to disregard the columns macros introduced by the |beamer| class
+% \begin{macrocode}
+%<*ltxml>
+DefEnvironment('{columns}','#body');
+DefEnvironment('{column}{}','#body');
+%</ltxml>
+% \end{macrocode}
+%
+% We also need to deal with overlay specifications introduced by the |beamer|
+% class.\ednote{this is just to keep latexml quiet, no real functionality here.}
+%
+% \ednote{Deyan: We reuse the CMP itemizations defined in the omdoc.cls.ltxml binding,

+%
+%\section{Introduction}\label{sec:intro}
+%
+% The |problem| package supplies an infrastructure that allows specify problem. Problems
+% are text fragments that come with auxiliary functions: hints, notes, and
+% solutions\footnote{for the momenet multiple choice problems are not supported, but may
+% well be in a future version}. Furthermore, we can specify how long the solution to a
+% given problem is estimated to take and how many points will be awarded for a perfect
+% solution.
+%
+% Finally, the |problem| package facilitates the management of problems in small files,
+% so that problems can be re-used in multiple environment.
+%
+% \section{The User Interface}\label{sec:ui}
+%
+% \subsection{Package Options}
+% The |problem| package takes the options \DescribeMacro{solutions}|solutions| (should
+% solutions be output?), \DescribeMacro{notes}|notes| (should the problem notes be
+% presented?), \DescribeMacro{hints}|hints| (do we give the hints?),
+% \DescribeMacro{pts}|pts| (do we display the points awarded for solving the problem?),
+% \DescribeMacro{min}|min| (do we display the estimated minutes for problem soling). If
+% theses are specified, then the corresponding auxiliary parts of the problems are output,
+% otherwise, they remain invisible.
+%
+% The \DescribeMacro{boxed} option specifies that problems should be formatted in framed
+% boxes so that they are more visible in the text. Finally, the \DescribeMacro{test}|test|
+% option signifies that we are in a test sitution, so this option does not show the
+% solutions (of course), but leaves space for the students to solve them.
+%
+% The \DescribeMacro{extract}|extract| option can be set if we want to extract a problems
+% file, e.g. to display the solutions, see Section~\ref{sec:user:includeproblem} for a
+% discussion.
+%
+% \subsection{Problems and Solutions}\label{sec:user:probsols}
+%
+% \DescribeEnv{problem} The main enviornment provided by the |problem| package is
+% (surprise surprise) the |problem| environment. It is used to mark up problems and
+% excercises. The environment takes an optional KeyVal argument with the keys
+% \DescribeMacro{id}|id| as an identifier that can be reference later,
+% \DescribeMacro{pts}|pts| for the points to be gained from this exercise in homework or
+% quiz situations, \DescribeMacro{min}|min| for the estimated minutes needed to solve the
+% problem, and finally \DescribeMacro{title}|title| for an informative title of the
+% problem. For an example of a marked up problem see Figure~\ref{fig:problem} and the
+% resulting markup see Figure~\ref{fig:result}.
+%
+%\begin{exfig}
+% \begin{verbatim}
+% \usepackage[solutions,hints,pts,min]{problem}
+% \begin{document}
+% \begin{problem}[id=elefants,pts=10,min=2,title=Fitting Elefants]
+% How many Elefants can you fit into a Volkswagen beetle?
+% \begin{hint} Think positively, this is simple!\end{hint}
+% \begin{exnote}Justify your answer\end{exnote}
+% \begin{solution}[for=elefants,height=3cm]
+% Four, two in the front seats, and two in the back.
+% \end{solution}
+% \end{problem}
+% \end{document}
+% \end{verbatim}
+% \caption{A marked up Problem}\label{fig:problem}
+% \end{exfig}
+%
+% \DescribeEnv{solution} The |solution| environment can be to specify a solution to a
+% problem. If the \DescribeMacro{solutions}|solutions| option is set or |\solutionstrue|
+% is set in the text, then the solution will be presented in the output. The |solution|
+% environment takes an optional KeyVal argument with the keys \DescribeMacro{id}|id| for
+% an identifier that can be reference \DescribeMacro{for}|for| to specify which problem
+% this is a solution for, and \DescribeMacro{height}|height| that allows to specify the
+% amount of space to be left in test situations (i.e. if the \DescribeMacro{test}|test|
+% option is set in the |\usepackage| statement).
+%
+%\begin{exfig}
+% \begin{minipage}{.9\linewidth}
+% \begin{problem}[id=elefants.prob,title=Fitting Elefants]
+% How many Elefants can you fit into a Volkswagen beetle?
+% \begin{hint} Think positively, this is simple!\end{hint}
+% \begin{exnote}Justify your answer\end{exnote}
+% \begin{solution}%[for=elefants.prob,height=3cm]
+% Four, two in the front seats, and two in the back.
+% \end{solution}
+% \end{problem}
+% \end{minipage}
+% \caption{The Formmatted Problem from Figure~\ref{fig:problem}}\label{fig:result}
+% \end{exfig}
+%
+% \DescribeEnv{hint}\DescribeEnv{note}, the |hint| and |exnote| environments can be used
+% in a |problem| enviroment to give hints and to make notes that elaborate certain aspects
+% of the problem.
+%
+% \subsection{Including Problems}\label{sec:user:includeproblem}
+%
+% The \DescribeMacro{\includeproblem}|\includeproblem| macro can be used to include a
+% problem 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 problem in the include file). The keys \DescribeMacro{title}|title|,
+% \DescribeMacro{min}|min|, and \DescribeMacro{pts}|pts| specify the problem title, the
+% estimated minutes for solving the problem and the points to be gained, and their values
+% (if given) overwrite the ones specified in the |problem| environment in the included
+% file.
+%
+% Sometimes we want to collect all the included problems into a separate file that can be
+% typeset independently. The main application is to have course notes into which the
+% problems are included (usually in boxed form to distinguish them from the rest of the
+% text and without solutions) and to have the problems with solutions in a separate file
+% (to encourage students to try and solve the problems before looking up solutions). In
+% this situation set the \DescribeMacro{extract}|extract| option on the notes file
+% \meta{notes}|.tex|, which causes a file \meta{notes}|-solutions.tex| to be generated
+% that has the |\includeproblem| statements with the respective numbers from the main
+% document. This can then be imported into a document with the respective front and
+% backmatter. In particular the frontmatter of the importing will ususlly specify the
+% \DescribeMacro{solutions}|solutions| option to generate solutions.
+%
+% \subsection{Reporting Metadata}\label{sec:user:reporting}
+%
+% The sum of the points and estimated minutes (that we specified in the |pts| and |min|
+% keys to the |problem| environment or the |\includeproblem| macro) to the log file and
+% the screen after each run. This is useful in preparing exams, where we want to make sure
+% that the students can indeed solve the problems in an alotted time period.
+%
+% The |\min| and |\pts| macros allow to specify (i.e. to print to the margin) the
+% distribution of time and reward to parts of a problem, if the |pts| and |pts| package
+% options are set. This allows to give students hints about the estimated time and the
+% points to be awarded.

+%
+% \section{The Implementation}\label{sec:implementation}
+%
+% \subsection{Package Options}\label{sec:impl:options}
+%
+% The first step is to declare (a few) package options that handle whether certain
+% information is printed or not. They all come with their own conditionals that are set by
+% the options.
+%
+% \begin{macrocode}
+%<*package>
+\newif\ifexnotes\exnotesfalse\DeclareOption{notes}{\exnotestrue}
+\newif\ifhints\hintsfalse\DeclareOption{hints}{\hintstrue}
+\newif\ifsolutions\solutionsfalse\DeclareOption{solutions}{\solutionstrue}
+\newif\ifpts\ptsfalse\DeclareOption{pts}{\ptstrue}
+\newif\ifmin\minfalse\DeclareOption{min}{\mintrue}
+\newif\ifboxed\boxedfalse\DeclareOption{boxed}{\boxedtrue}
+\newif\ifextract\extractfalse\DeclareOption{extract}{\extracttrue}
+\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{xcomment}
+\RequirePackage{sref}
+%</package>
+% \end{macrocode}
+%
+% Here comes the equivalent header information for {\LaTeXML}, we also initialize the
+% package inclusions. Since {\LaTeXML} currently does not process package options, we have
+% nothing to do.
+% \begin{macrocode}
+%<*ltxml>
+# -*- CPERL -*-
+package LaTeXML::Package::Pool;
+use strict;
+use LaTeXML::Package;
+RequirePackage('sref');
+%</ltxml>
+% \end{macrocode}
+%
+% Then we register the namespace of the requirements ontology
+% \begin{macrocode}
+%<*ltxml>
+RegisterNamespace('prob'=>"http://omdoc.org/ontology/problems#");
+RegisterDocumentNamespace('prob'=>"http://omdoc.org/ontology/problems#");
+%</ltxml>
+% \end{macrocode}
+%
+% \subsection{Problems and Solutions}\label{sec:impl:probsols}
+%
+% We now prepare the KeyVal support for problems. The key macros just set appropriate
+% internal macros.
+%
+% \begin{macrocode}
+%<*package>
+\srefaddidkey[prefix=prob.]{problem}
+\omdaddkey{problem}{pts}
+\omdaddkey{problem}{min}
+\omdaddkey{problem}{title}
+\omdaddkey{problem}{refnum}
+% \end{macrocode}
+%
+% Then we set up a box and a counter for problems
+%
+% \begin{macrocode}
+\newsavebox{\probbox}
+\newcounter{problem}[section]
+% \end{macrocode}
+%
+% \begin{macro}{\prob@number}
+% We consolidate the problem number into a reusable internal macro
+% \begin{macrocode}
+\def\prob@number{\ifx\inclprob@refnum\@empty
+\ifx\problem@refnum\@empty\thesection.\theproblem\else\problem@refnum\fi
+\inclprob@refnum\fi}
+% \end{macrocode}
+% \end{macro}
+%
+% We consolidate the problem header line into a separate internal macro that can be reused
+% in various settings.
+%
+% \begin{macro}{\prob@heading}
+% We consolidate the problem header line into a separate internal macro that can be
+% reused in various settings.
+% \begin{macrocode}
+\def\prob@heading{Problem \prob@number%
+\ifx\sref@id\@empty\else{\sref@label@id{Problem \thesection.\theproblem}}\fi%
+\ifx\inclprob@title\@empty% if there is no outside title
+\ifx\problem@title\@empty{:\quad}\else{\quad(\problem@title)\hfill\\}\fi
+\else\quad(\inclprob@title)\hfill\\\fi}% else show the outside title
+% \end{macrocode}
+% \end{macro}
+%
+% With this in place, we can now define the |problem| environment. It comes in two shapes,
+% depending on whether we are in boxed mode or not. In both cases we increment the problem
+% number and output the points and minutes (depending) on whehter the respective options
+% are set.
+% \begin{environment}{problem}
+% \begin{macrocode}
+\ifboxed
+\newenvironment{problem}[1][]{\omdsetkeys{problem}{#1}\sref@target%
+\stepcounter{problem}\show@pts\show@min\record@problem%
+\begin{lrbox}{\probbox}\begin{minipage}{.9\textwidth}}
+{\end{minipage}\end{lrbox}
+\setbox0=\hbox{\begin{minipage}{.9\textwidth}%
+\noindent\textbf\prob@heading\rm%
+\end{minipage}}
+\smallskip\noindent\fbox{\vbox{\box0\vspace*{.2em}\usebox\probbox}}\smallskip}
+\else
+\newenvironment{problem}[1][]{\omdsetkeys{problem}{#1}\sref@target%

+\par\noindent\textbf\prob@heading\rm}
+{\smallskip}
+\fi%boxed
+%</package>
+% \end{macrocode}
+% \end{environment}
+%
+% Note that we allow hints and solutions in the body of a |problem| environment so we have
+% to allow the |omdoc:CMP| and |omdoc:p| elements to autoclose.
+%
+% \begin{macrocode}

+% \subsection{Including Problems}\label{sec:impl:includeproblem}
+%
+% The first action is to make a \meta{jobname}|-problems.tex| file, if the |extract|
+% option is set.
+%

+%
+% \begin{macro}{\includeproblem}
+% The |\includeproblem| command is essentially a glorified |\input| statement, it sets
+% some internal macros first that overwrite the local points. After that (so that the
+% included problem had time to step the problem number) it writes the |\includeproblem|
+% statement to the problems file, if the |extract| option is set. Here we add a key
+% |refnum=\prob@num| to the inlcudeproblem, so that we can remember the number from the
+% main document.\ednote{do something about the overwriting of problem metadata in the
+% {\LaTeXML} binding.}

+% then we show them in the margin.
