+%
+%\clearpage\section{General information} This manual provides
+%information about working with the \pf{HA-prosper} package. This
+%package is a patch for the \pf{prosper} class. Be sure to also study
+%the documentation of the \pf{prosper} class and the \pf{hyperref}
+%package. You can find this documentation for instance at the CTAN
+%site for prosper \cite{prosperCTAN}, at the \pf{prosper} website
+%\cite{prosper} or in your local \LaTeX\ distribution (for the MiKTeX
+%distribution \cite{MiKTeX}, the documentation can be found in the
+%|doc| directory in the MiKTeX root). Information about \pf{prosper}
+%can also be found at the WikiProsper site \cite{WikiProsper}.
+%
+%If you want to start working with \pf{HA-prosper} immediately, have
+%a look at the examples (see section~\ref{sec:examples}). If you are
+%interested in how \pf{HA-prosper} actually works, have a look at the
+%first lines of the source code available in the |Source| directory
+%of the package or the |source| tree of your \LaTeX\ distribution
+%which explains how to generate the source code documentation.
+%
+%Note that from version 4.1, \pf{HA-prosper} uses the \pf{xkeyval}
+%package, which is available from CTAN \cite{xkeyvalCTAN} and is
+%included in the MiKTeX distribution. Do not forget to install this
+%package. See also section~\ref{sec:req}.
+%
+%Do not forget to check the \pf{HA-prosper} website
+%\cite{HA-prosper} from time to time to see if there are updates
+%for this package or new styles available. If, \emph{after reading
+%this manual}, you have questions or comments about
+%\pf{HA-prosper}, see section~\ref{sec:questions}.
+%
+%\subsection{The \pf{powerdot} class}\label{sec:newclass}
+%This is the last release of the \pf{HA-prosper} package. We
+%(Christopher Ellison and I) have created a new class called
+%\pf{powerdot} \cite{powerdot} which has significant improvements
+%over \pf{prosper} and \pf{HA-prosper} while keeping changes to
+%presentation sources to a minimum. Over time, the support for
+%\pf{HA-prosper} via the mailinglist will be minimized and users are
+%advised to use \pf{powerdot} for new presentations.
+%
+%Further, information in this documentation was up to date in 2004,
+%but might be outdated by now. The reason of not updating this is
+%that since then all efforts have concentrated on the \pf{powerdot}
+%class.
+%
+%\subsection{Compatibility}
+%This section discusses compatibility issues between \pf{HA-prosper}
+%and some other packages. The \pf{HA-prosper} package has been
+%created and tested in an environment of MiKTeX 2.3 \cite{MiKTeX} and
+%GhostScript 8.00 \cite{GhostScript} and newer versions of that
+%software.
+%
+%\subsubsection{prosper}
+%Since \pf{HA-prosper} is a patch for \pf{prosper}, it is important
+%that you have the right version of \pf{prosper} which is 1.5
+%(|prosper.cls| version 1.24)\footnote{This package is also
+%compatible to the CVS version 1.25 of \pf{prosper}, but that
+%version is still in beta stage and it is advisory not to use it.
+%If you still want to use version 1.25 because of v\TeX\ support,
+%delete or comment line 88 of |prosper.cls| then, namely were the
+%\pf{pstcol} package is loaded, since that causes colors not to be
+%defined properly.}. This is the CTAN version \cite{prosperCTAN}.
+%
+%\subsubsection{ppr-prv}
+%A very nice package in combination with \pf{HA-prosper} is the
+%`Prosper Preview' class, \pf{ppr-prv} \cite{ppr-prv}, created by
+%Mathieu Goutelle \cite{Mathieu}. The aim of this class is to produce
+%a printable version of the slides written with \pf{prosper} or
+%\pf{HA-prosper} with two slides (or more at will) per page and a
+%table of contents on the first page in case you are using
+%\pf{HA-prosper}. Table~\ref{tab:pprpprvcompat} shows which versions
+%of \pf{ppr-prv} and \pf{HA-prosper} are compatible. Each row of the
+%table lists the compatible versions.
+%\begin{table}[ht]
+%\centering\caption{Compatible versions of \pf{HA-prosper} and
+%\pf{ppr-prv}.}\label{tab:pprpprvcompat}
+%\begin{tabular}{f}
+%\pf{HA-prosper}&\pf{ppr-prv}&\pf{HA-prosper}&\pf{ppr-prv}\\\hline\hline
+%3.7x&0.09&3.8&0.10\\\hline
+%3.9&0.11&4.0&0.12\\\hline
+%4.11&0.13&4.2&0.13\\\hline\hline
+%\end{tabular}
+%\end{table}
+%
+%\subsubsection{semcolor/pstcol/pstricks/color/xcolor}
+%Recently, the incompatibilities of these packages have been solved
+%and through a modification of \pf{semcolor}, the improved
+%compatibility is also available to \pf{HA-prosper} users. Check the
+%documentation of these packages to see whether or not your \LaTeX\
+%distribution already includes the compatible versions. If so, then
+%you can use both \pf{pstricks} color commands in your presentation
+%or style as well as \pf{xcolor} commands.
+%
+%\subsubsection{babel}
+%\pf{HA-prosper} redefines the |itemize| and the |enumerate|
+%environments at the beginning of the document. This solves a bug
+%that would otherwise occur when using the \pf{babel} package with
+%the |french| option. The \pf{prosper} macro
+%|\NoFrenchBabelItemize| is obsolete in \pf{HA-prosper} and has
+%no function anymore. The order of loading the packages is
+%important since \pf{HA-prosper} attempts to redefine some
+%\pf{babel} macros. In case you want to use \pf{babel}, load
+%\pf{babel} first and afterwards \pf{HA-prosper}.
+%
+%\subsubsection{Miscellaneous}
+%Older versions of GhostScript might produce ugly display text and
+%logo's. However, prints are fine in general. Furthermore, it has
+%been shown that Acrobat Reader 4 \cite{AcroRead} generally does not
+%display pictures properly.
+%
+%Since the |overlays| macro is not recognized by Scientific
+%WorkPlace \cite{SWP}, this program is not supported. The advice is
+%to use an editor for creating the slides, for example WinEdt
+%\cite{WinEdt} or TexNicCenter \cite{TexNicCenter} (free).
+%
+%\subsection{Installation}\label{sec:inst}
+%This package is included in the MiKTeX distribution \cite{MiKTeX}
+%and in TeXLive \cite{TeXLive} and can be installed for you by
+%these programs. However, if you downloaded this package from the
+%\pf{HA-prosper} website \cite{HA-prosper} or from the
+%\pf{HA-prosper} CTAN directory \cite{HA-prosperCTAN}), then here
+%are some hints for installing the package into your \LaTeX\
+%distribution.
+%
+%The package includes pre-generated run and doc files, but you can
+%reproduce them from the source if necessary. See the first lines
+%of |HA-prosper.dtx| for information how to do this. The files
+%in |Doc| should go into the |doc| tree of your distribution,
+%the files in |Run| into the |tex| run tree and the files in
+%|Source| into the |source| tree. See the documentation of
+%your \LaTeX\ distribution for information on installing
+%\pf{HA-prosper} into your \LaTeX\ distribution or the TeX
+%Frequently Asked Questions \cite{TeXFAQInst}.
+%
+%If you choose not to install the package into your \LaTeX\
+%distribution, you can copy the necessary files (that is, the run
+%files of \pf{HA-prosper} in the |Run| directory and the
+%necessary files of the particular style, which can all be found in
+%the relevant subdirectory of the |Run| directory) into your
+%working directory.
+%
+%\subsection{Document set up}\label{sec:setup}
+%The structure of a presentation created with \pf{HA-prosper} is
+%comparable to that of a \pf{prosper} presentation. See the
+%\pf{prosper} documentation for an overview.
+%
+%Do not forget to include
+%\begin{verbatim}
+%\usepackage[style,options]{HA-prosper}
+%\end{verbatim}
+%directly after the \pf{prosper} document class command to be able
+%to use the new definitions provided in |HA-prosper.sty|. Here
+%|style| is the style you want to use, for instance |HA|, and
+%|options| are any package options which will be described in
+%section~\ref{sec:new}. A summary of these options can be found in
+%section~\ref{sec:packageoptions}.
+%
+%\DescribeMacro{\HAPsetup}
+%You can set up certain features like footers and types of stepping
+%environments globally (holding for the entire presentation, unless
+%specified otherwise locally) using |\HAPsetup|, for instance
+%\begin{verbatim}
+%\HAPsetup{rf={My presentation},trans=Dissolve}
+%\end{verbatim}
+%This command can set up the features that you will be discussed in
+%section~\ref{sec:new}. You can find a summary in
+%section~\ref{sec:globals}.
+%
+%\subsection{Summary of package options}\label{sec:packageoptions}
+%Table~\ref{tab:packageoptions} contains a summary of all package
+%options of \pf{HA-prosper}. The numbers in between brackets are
+%the sections where you can find more information about a specific
+%option. See section~\ref{sec:setup} how to use these options.
+%\begin{table}[ht]
+%\caption{\pf{HA-prosper} package
+%options.}\label{tab:packageoptions}\makebox[\textwidth][r]{
+%\begin{tabular}{d}
+%\hline\hline
+%|sounds|& Turns on the |sound| key for slide environments (\ref{sec:slide}).\\\hline
+%|toc|& Creates a table of contents on slides (\ref{sec:toc}).\\\hline
+%|highlight|& Highlights the current slide in the table of contents (\ref{sec:tochl}).\\\hline
+%|hlsections|& Highlights the current section on every slide within the section (\ref{sec:tochl}).\\\hline

+%|blackslide|& Includes a black slide at the start of the presentation (\ref{sec:blslide}).\\\hline
+%\hline
+%\end{tabular}}
+%\end{table}
+%
+%\subsection{Summary of global options}\label{sec:globals}
+%Table~\ref{tab:hapsetupfeats} lists all the features of
+%\pf{HA-prosper} that can be set using |\HAPsetup|. The numbers
+%in between brackets are the sections where you can find more
+%information about a specific feature. See section~\ref{sec:setup}
+%how to use these global options.\par
+%\begin{table}[ht]\caption{Global
+%\pf{HA-prosper} options for \ci{HAPsetup}.}\label{tab:hapsetupfeats}
+%\makebox[\textwidth][r]{
+%\begin{tabular}{e}\hline\hline
+%|lf|&Left footer (\ref{sec:footers}).&|sound|&Transition sound (\ref{sec:slide}).\\\hline
+%|rf|&Right footer (\ref{sec:footers}).&|template|&Template for parts (\ref{sec:part}).\\\hline
+%|sn|&Slide number layout (\ref{sec:footers}).&|stype|&Stepping environment type (\ref{sec:iestep}).\\\hline

+%|trans|&Transition effect (\ref{sec:slide}).&|counters|&Protect custom counters (\ref{sec:numbering}).\\\hline\hline
+%\end{tabular}}
+%\end{table}
+%The features listed in table~\ref{tab:hapsetupfeats} all have a
+%default value, which are discussed in the relevant sections. These
+%values are defined in the file |HA-prosper.cfg|. This file can
+%be modified. Modifications will have an effect on all
+%presentations created using \pf{HA-prosper}\footnote{Note that the
+%defaults saved in the |HA-prosper.cfg| file at the moment of
+%installation are also saved in |HA-prosper.sty|. In case you
+%accidentally delete a line in the |HA-prosper.cfg| file, the
+%predefined defaults in |HA-prosper.sty| will be used.}.
+%
+%\subsection{Compilation}\label{sec:compile}
+%If you use the |pdf| option in the |\documentclass|, compile with
+%LaTeX2DVI - DVI2PS - PS2PDF to create slides with animations
+%(incrementally displayed items created by the |itemstep|
+%environment) that can be projected using for instance Acrobat Reader
+%\cite{AcroRead}. Notice that \pf{HA-prosper} is build to work with
+%papertype |letter| in the DVI2PS step (which is the default in the
+%MiKTeX distribution and which can be achieved by adding |-t letter|
+%to the command line of |dvips|), but the |Fyma| style supports |A4|
+%paper as well. See section~\ref{sec:supportt}.
+%
+%If you want to print the slides, use the |ps2pdf| option and
+%compile them with LaTeX2DVI - DVI2PS - PS2PDF and you can print
+%the slides without animations.
+%
+%You can also use the Acrobat Distiller (included in Acrobat
+%\cite{Acrobat}) to create the PDF from the PS file. This creates
+%very efficient PDF files. Also see section~\ref{sec:result}. Do
+%not forget to specify the \pf{prosper} class option `distiller' in
+%this case to avoid errors when distilling the PS document. For
+%instance
+%\begin{verbatim}
+%\documentclass[pdf,distiller]{prosper}
+%\end{verbatim}
+%
+%If you prefer to use GhostView \cite{GhostView} for printing
+%purposes, you can of course suffice with LaTeX2DVI - DVI2PS and
+%print the slides form GhostView\footnote{You might have to shrink
+%pages to fit the paper when printing the slides.}.
+%
+%A nice option for the `documentclass' is `draft'. This is provided
+%by \pf{prosper} and speeds up the process of compiling and
+%viewing the presentation by leaving out images. Deleting the
+%option produces a presentation that includes all images again. See
+%the \pf{prosper} class documentation for more details.
+%
+%\subsection{Upgrade information}
+%This section contains information how to change your presentation
+%in case you worked with an earlier version of \pf{HA-prosper}
+%before and want to upgrade it. The list below contains the hints
+%for upgrading with a single version step at a time. If you for
+%instance want to upgrade from version 3.5 to the latest version,
+%read all the entries in the list starting from the entry right the
+%entry of version 3.5. If a particular version is not mentioned,
+%this means that no changes need to be made to adapt the
+%presentation to that version when starting at the last version
+%before.
+%
+%\begin{itemize}
+%\item[\fbox{3.0}] From \pf{HA-prosper} version 3.0, the
+%package is based on the CTAN version of \pf{prosper}. This means
+%that a separate version of \pf{prosper} is not distributed with
+%this package anymore. If you used \pf{HA-prosper} before, replace
+%the old style-file with the new one to upgrade to the latest
+%version of \pf{HA-prosper} and do not forget to rename or delete
+%prosper.cls in the working directory. \item[\fbox{3.5}] From
+%version 3.5 of \pf{HA-prosper} the style definitions (template)
+%will be loaded by \pf{HA-prosper}, not by \pf{prosper} anymore.
+%This is done to avoid conflict when trying to use \pf{HA-prosper}
+%templates with \pf{prosper}. Delete the style from the
+%|\documentclass| command and put it in the |\usepackage|
+%command of \pf{HA-prosper} when updating \pf{HA-prosper}. See also
+%section~\ref{sec:inst}.
+%\item[\fbox{3.6x}]\begin{itemize} \item When upgrading to
+%\pf{HA-prosper} version 3.6, you might need to delete the
+%|.toc| file of an existing presentation first since table
+%of contents commands have changed and the new \pf{HA-prosper}
+%is not able to understand the old commands. \item The
+%|\email| and |\institution| commands have changed.
+%In earlier version, defining them in the preamble of your
+%presentation would make them appear on the title slide. Now, you
+%have to put them inside the |\author| command. See
+%section~\ref{sec:eia} for an example.
+%\end{itemize}
+%\item[\fbox{3.7x}]\begin{itemize} \item Download the full package
+%to use the latest versions of the styles that are compatible to
+%this version of \pf{HA-prosper}. \item Rename
+%|\section| and |\sectionandpart| to
+%|\tsection| and |\tsectionandpart| respectively.
+%\end{itemize}
+%\item[\fbox{3.8}]\begin{itemize} \item Download the full package
+%to use the latest versions of the styles that are compatible to
+%this version of \pf{HA-prosper}. \item Rename
+%|\figureitem| to |\hiddenitem|. See
+%section~\ref{sec:xitemwait}.\item Change slides that use the
+%|dualslide| environment to for instance a normal
+%|slide| and use the |\dualslide| macro to create a
+%dualslide on that slide. See
+%section~\ref{sec:dualslide}.\end{itemize}
+%\item[\fbox{3.9}]
+%\begin{itemize} \item |\figureitem| and
+%|\putfigureitem| are no longer supported;
+%|\putfigure| should be replaced by the more general
+%|\topbl|, see section~\ref{sec:xitemwait}. \item The
+%dualslide dimensions have changed a bit, see
+%section~\ref{sec:dualslide}.\item More optional arguments for the

+%
+%\clearpage\section{New or changed environments and
+%commands}\label{sec:new} This section describes the new commands
+%provided by \pf{HA-prosper} and the originally \pf{prosper} commands
+%that have been extended. The section assumes knowledge of the
+%\pf{prosper} documentation.
+%
+%\subsection{The slide environment}\label{sec:slide}
+%\DescribeEnv{slide}
+%A slide is created using the |slide| environment. For instance
+%\begin{verbatim}
+%\begin{slide}[trans=Replace]{Sample slide}
+%...
+%\end{slide}
+%\end{verbatim}
+%The new |slide| environment has four options. They are
+%listed in table~\ref{tab:slide}.
+%\begin{table}[ht]
+%\caption{Slide environment options.}\label{tab:slide}
+%\makebox[\textwidth][r]{
+%\begin{tabular}{d}\hline\hline
+%|toc|&When specified, it will be used for the table of contents. When not\\
+%&specified, the slide title will be used to create a toc entry (see section~\ref{sec:toc}).\\\hline
+%|bm|&When specified, it will be used to create a bookmark. If not, the slide\\
+%&title will be used as a bookmark.\\\hline
+%|trans|&Slide transition effect (see the \pf{prosper} documentation) Default: |Replace|.\\\hline
+%|sound|&Specify a sound file to be played when the slide is displayed.\\\hline
+%\hline
+%\end{tabular}}
+%\end{table}
+%Some remarks need to be made. First of all, when you supply an
+%empty string as bookmark (so |bm=|), the bookmark will not be
+%created. A similar thing holds for empty toc strings (|toc=|).
+%See section~\ref{sec:toc}. The bookmark option is supplied to
+%provide low level text for creating a bookmark in case you want
+%the slide title to contain \LaTeX\ commands which might not be
+%convertable to bookmarks\footnote{Note that the bookmarking
+%procedure uses \ci{pdfstringdef} of \pf{hyperref} which is able
+%to process things like \ci{"i}.}. For instance:
+%\begin{verbatim}
+%\begin{slide}[bm=Important!]{\red Important!}
+%\end{verbatim}
+%
+%\DescribeSwitch{sounds}
+%Second, adding transition sounds to a presentation is possible,
+%but it is important to know that the sounds will not be embedded
+%in the presentation and hence need to be supplied separately.
+%Further, the presentation becomes system dependent by using
+%sounds. It depends on the target machine if the specific sound
+%file can be played or not. To switch on the use of sounds in your
+%presentation, use the package option |sounds|, see
+%section~\ref{sec:packageoptions}.
+%
+%The options |trans| and |sound| can be set globally by |\HAPsetup|
+%(see section~\ref{sec:globals})\footnote{Notice that backward
+%compatibility for \ci{DefaultTransition} is provided.}. The |sound|
+%slide option adds the transition sound to all slides within
+%|\overlays|. For more flexibility, the sound option also has a user
+%interface to set sounds on pages directly. The sound file
+%\DescribeMacro{\SlideSound}
+%|sound.wav| is added using |\SlideSound| as follows.
+%\begin{verbatim}
+%\SlideSound{sound.wav}
+%\end{verbatim}
+%This code adds a transition sound to the first overlay only:
+%\begin{verbatim}
+%\onSlide*{1}{\SlideSound{sound.wav}}
+%\end{verbatim}
+%(see also section~\ref{sec:onslide} for the use of |\onSlide|).
+%
+%\subsection{Structuring the presentation}\label{sec:toc}
+%\subsubsection{Building a table of contents}
+%\DescribeSwitch{toc}
+%You can include a table of contents on each slide. This can be
+%used for navigational purposes during the presentation. When
+%printing the slides, you might decide to leave out the table of
+%contents. You can request a table of contents by specifying the
+%option |toc| in the |\usepackage| command for the style
+%file, like
+%\begin{verbatim}
+%\usepackage[toc,HA]{HA-prosper}
+%\end{verbatim}
+%(see also the examples in this distribution). \pf{HA-prosper} will
+%use slide titles by default to produce the table of contents, but
+%this behavior can be changed (see section~\ref{sec:slide}).
+%
+%Some remarks. First of all, the table of contents will of course
+%only be put on the slides when it has been implemented in the style
+%that you are using. See section~\ref{sec:supportt}. Second,
+%\pf{HA-prosper} offers possibilities for style developers to split
+%the table of contents into two parts the first of which will contain
+%the sections and the second will contain the content of the current
+%section.
+%
+%Third, if you specify an empty string as toc entry (so |toc=|),
+%the toc entry will be deleted from the table of contents. This
+%allows for building an overview of your presentation. Hence the
+%table of contents can both be used for navigational purposes (like
+%the bookmarks) and to provide an overview of the presentation.
+%
+%Finally, as with a usual table of contents in \LaTeX, you need to
+%run your presentation at least twice after altering slides or toc
+%entries. On the first pass, the table of contents will be updated
+%and on the second run, the new table of contents will be included
+%in the presentation.
+%
+%\subsubsection{Highlighting table of contents entries}\label{sec:tochl}
+%\DescribeSwitch{highlight}
+%If you want to highlight the current slide or the slide created by
+%a |\part| or |\tsectionandpart| command (see section~\ref{sec:pas})
+%in the table of contents, specify the
+%|highlight| option, like
+%\begin{verbatim}
+%\usepackage[toc,highlight,HA]{HA-prosper}.
+%\end{verbatim}
+%Of course, the |highlight| option only takes effect when
+%also the |toc| option has been specified (and of
+%course the style you are using should support highlighting and the
+%table of contents). This |highlight| option can be nice
+%for both yourself and the audience since everyone can clearly see
+%on which slide or in which section of the presentation you are.
+%
+%\DescribeSwitch{hlsections}
+%An extra option is the |hlsections| option. This will make the
+%current section highlighted on every slide within the current
+%section. This can be especially useful when sections and section
+%content are split in the style that you use, which would otherwise
+%result in unclarities about the current section\footnote{Splitting
+%of the table of contents is often implemented on portrait
+%templates.}. When the table of contents is not split up, this option
+%might be left out since in this case, the hierarchical structure of
+%the table of contents clearly identifies the current section.
+%
+%\subsection{Parts and sections}\label{sec:pas}
+%\subsubsection{tsection}\label{sec:section}
+%\DescribeMacro{\tsection}
+%By using the |\tsection|
+%command, it is possible to divide the table of contents in several
+%sections. The content of a section will be hidden until you access
+%a slide inside this section. The section heading in the table of
+%contents itself refers to the first slide after the section
+%command. The section command should be used between slides. The
+%following shows an example.
+%\begin{verbatim}
+%\begin{slide}{First slide}
+%Some text
+%\end{slide}
+%
+%\tsection[Bookmark for section 1]{Section 1}
+%
+%\begin{slide}{Second slide}
+%Some text
+%\end{slide}
+%\end{verbatim}
+%The optional argument of the |\tsection| macro can be used
+%to specify the string to be used for the bookmark. Notice that all
+%slides that are met before issuing the first |\tsection|
+%command will always be displayed in the table of contents.
+%Exceptions hold for two cases. The first is when issuing an empty
+%string as toc entry in the |slide| environment (see
+%section~\ref{sec:slide}). The second is when the style that you
+%are using implements a split table of contents. In this case, the
+%content of every new section will replace the content of the old
+%section when going from the old section to the new section. The
+%entries before the first section will then be replaced by the
+%entries of the first section when advancing to that section.
+%
+%\DescribeMacro{\tsection*}
+%Furthermore, |\tsection*| is available. It has the exact same
+%possibilities as |\tsection|, but this command hides the section
+%created by |\tsection*| completely until you enter it (for instance
+%with a hyperlink to a slide, by using bookmarks or by browsing the
+%slides). This can be useful if you want to include slides in your
+%presentation, that you don't want to show in the table of contents,
+%but which you could include into the presentation if you see that
+%you have some time left. But there are of course other applications
+%thinkable.
+%
+%\subsubsection{part}\label{sec:part}
+%\DescribeMacro{\part}
+%The |\part| command lets you identify separate parts in your
+%presentation. The command |\part{Part I}| produces a normal slide
+%with horizontally centered the words `Part I'. The argument will
+%also be used to create a bookmark and a toc entry (if a table of
+%contents is requested). The |\part| takes the same options as the
+%|slide| environments (see section~\ref{sec:slide}), but it should be
+%noted that in case you specify an empty string for the |bm| option,
+%the part title will be used to create the bookmark.
+%
+%An additional option for the |\part| command is the
+%|template| option. This allows to select a different
+%template (supplied by the style that you use) for the slide
+%created by the |\part| command. For instance, the HA-style
+%supplies the template `wideslide'. You can use that template for
+%the part to delete the table of contents from that particular
+%slide. Example:
+%\begin{verbatim}
+%\part[template=wideslide,toc=Part number one,bm=The first part]{Part I}
+%\end{verbatim}
+%
+%Note that the option |template| can be set globally for the entire
+%presentation (see section~\ref{sec:globals}). The default value of
+%|template| is |slide|.
+%
+%\subsubsection{tsectionandpart}\label{sec:secandpart}
+%\DescribeMacro{\tsectionandpart}
+%The
+%|\tsectionandpart| command is a combination of the
+%|\tsection| command (see section~\ref{sec:section}) and the
+%|\part| command (see section~\ref{sec:part}). This command
+%is supplied since issuing the two previous commands after each
+%other cannot replicate the output of |\tsectionandpart|.
+%The command has the same optional arguments as the |\part|
+%command and besides creating a slide, it also creates a section in
+%the table of contents. The section heading in the table of
+%contents will now refer to the slide created by the |\part|
+%command.
+%
+%\DescribeMacro{\tsectionandpart*}
+%Notice that |\tsectionandpart*| produces similar output as
+%|\tsection*|. Namely, it hides the section in the table of
+%contents completely until it is accessed by going to any slide
+%within this section. See also section~\ref{sec:section}. As
+%|\tsectionandpart|, it also creates a |\part| slide.
+%
+%\subsection{Dualslide}\label{sec:dualslide}
+%\DescribeMacro{\dualslide}
+%The |\dualslide| macro allows to split content into two
+%columns. Usage:
+%\begin{samepage}
+%\begin{verbatim}
+%\dualslide[opt1][opt2][opt3]{options}{left}{right}
+%\end{verbatim}
+%The parameters are explained in
+%table~\ref{tab:dspars}.\end{samepage}\par

+%Important to notice is that the |\dualslide| macro uses the
+%current cursor position as the reference point to position the
+%first line of text of the left column (see also
+%figure~\ref{fig:dsldim}). This means that optional frames can
+%extend to the text on the previous line. Use for instance
+%|topsep=0.3cm| in that case to add extra space between the
+%two lines of text. The default value of |topsep| is based
+%on the situation that there is no text on top of the two columns.
+%In that case, it is best to locate the first line of text of the
+%left column at the same spot as text that is not created by
+%|\dualslide| on other slides. The setting
+%|topsep=0cm| does exactly this. However, with a combination
+%of |topsep| and |indent| you can change this
+%behavior and position the first line of text of the left column
+%anywhere you want.
+%
+%The dualslide macro computes the height of the construction to
+%position text below the construction correctly. The computation is
+%done by taking the maximum height of |lfrheight|,
+%|rfrheight|, |lineheight| (if requested) and the
+%left and right column content. Hence when frames nor a line is
+%requested, |bottomsep| is the vertical space between the
+%lowest line of text in the columns and the text below the columns
+%(additional to |\baselineskip|).
+%
+%Furthermore, if none of the optional arguments has been specified,
+%|dualslide| will use the \pf{PSTricks} defaults for
+%creating frames and the line. Two exceptions:
+%|linewidth=.25pt| and |linecolor=HAP@framecolor| by
+%default, but these can of course again be changed using the
+%optional arguments. When only |opt1| has been specified,
+%this is used globally for both frames and the line. When both
+%|opt1| and |opt2| have been specified, |opt1|
+%will be used for both frames and |opt2| will be used for
+%the line. In case you want to change the properties of the right
+%frame only, call for instance
+%\begin{verbatim}
+%\dualslide[ ][ ][linecolor=red]{rfrheight=6cm}{left content}{right content}
+%\end{verbatim}
+%
+%More examples can be found in the example files of \pf{HA-prosper},
+%see section~\ref{sec:examples}. Also have a look at
+%section~\ref{sec:animating} for information about animating content.
+%The commands described there can also be used to animated content in
+%the two columns.
+%
+%\subsection{Animating content}\label{sec:animating}
+%\subsubsection{itemstep and enumstep}\label{sec:iestep}
+%\DescribeEnv{itemstep}
+%\DescribeEnv{enumstep}
+%The |itemstep| and |enumstep| environments are based
+%on the |itemize| and |enumerate| environments
+%respectively, but with these environments, items will be displayed
+%incrementally. Available options can be found in
+%table~\ref{tab:iestepopts}.
+%\begin{table}[ht]
+%\caption{Itemstep and enumstep
+%options.}\label{tab:iestepopts}
+%\makebox[\textwidth][r]{
+%\begin{tabular}{d}
+%\hline\hline
+%|sstart|& Starts the stepping environment on overlay |sstart|. Default: 1.\\\hline
+%|iacolor|& Inactive color, used for inactive items. Default: lightgray.\\\hline
+%|stype|& Type of stepping environment. Default: 0. Possible:\\
+%&0 -- items appear one by one, but remain active;\\
+%&1 -- items appear one by one, but turn inactive when moving to the next item;\\
+%&2 -- all items are displayed and only one is active at a time.\\
+%\hline\hline
+%\end{tabular}}
+%\end{table}
+%These environments can be nested into each other and lower level
+%environments inherit options from higher level environments. The
+%|sstart| option has effect only in the highest level stepping
+%environment (which can be embedded in an |itemize| or |enumerate|
+%environment). The items of an |itemize| environment, which is nested
+%in a stepping environment, will inherit the state (active or not)
+%from the item in the stepping environment to which the
+%(sub)environment(s) belong to. If |itemize| or |enumerate| is used
+%at the top level, all items are active on all overlays. Find an
+%example below (for the meaning of |\xitem|, refer to
+%section~\ref{sec:xitem}).
+%\begin{verbatim}
+%\overlays{6}{
+%\begin{slide}{xitem example}
+%Some text.
+%  \begin{itemstep}[sstart=2,stype=0,iacolor=gray]

+%      \xitem item 1.1
+%      \xitem item 1.2
+%    \end{enumstep}
+%    \xitem item 2
+%    \xitem item 3
+%  \end{itemstep}
+%\end{slide}
+%}
+%\end{verbatim}
+%See section~\ref{sec:examples} for more examples and section
+%\ref{sec:xitemwait} for a tool for these environments. The
+%options for the stepping environments can also be set globally
+%using the |\HAPsetup| macro (see section~\ref{sec:globals}).
+%
+%Note that the use of type 1 or 2 stepping environments requires
+%the definition of the color |HAP@textc| by the template
+%that you use. See section~\ref{sec:styledev}.
+%
+%\subsubsection{xitem}\label{sec:xitem}
+%\DescribeMacro{\xitem}
+%\pf{HA-prosper} defines a new command, |\xitem|, to be used within
+%|itemize|, |enumerate|, |itemstep| and |enumstep| environments.
+%Within |itemstep| and |enumstep| environments it will take care of
+%the animation effect discussed in section~\ref{sec:iestep}. Within
+%|itemize| and |enumerate| environments it will just display the
+%content. Defining this command is necessary since redefining |\item|
+%would damage macros and environments using |\item| (for instance
+%|center|, |flushright|, |flushleft|).
+%
+%The |\xitem| macro also has a version in which it takes an optional
+%value $n$ by doing |\xitem<n>|. This value is the extra number of
+%overlays that the item should remain active in a stepping
+%environment and is ignored in an |itemize| or |enumerate|
+%environment. This optional argument can be useful when you want to
+%add content to the current item on a later overlay. Notice that this
+%can make several items active at a particular overlay. To avoid
+%this, add |\xitemwait| before the next item. See the example below
+%and section~\ref{sec:xitemwait}.
+%\begin{verbatim}
+%\overlays{3}{
+%\begin{slide}{xitem example}
+%\begin{itemstep}[stype=1]
+%  \xitem<1> Yes?
+%  \onSlide{2-}{No!}
+%  \xitemwait
+%  \xitem Because...
+%\end{itemstep}
+%\end{slide}
+%}
+%\end{verbatim}
+%
+%Note that a possibly unfamiliar syntax has been chosen for
+%|\xitem<n>|. This done to easily support the other optional argument
+%that comes with |\xitem| since it is an extension of the standard
+%|\item|. The optional argument allows you to overwrite the item
+%label, for instance |\xitem[a]| or |\xitem<1>[b]|. See your favorite
+%\LaTeX\ manual for more information about the latter.
+%
+%\subsubsection{xitemwait}\label{sec:xitemwait}
+%\DescribeMacro{\xitemwait}
+%The command |\xitemwait| tells \pf{HA-prosper} to wait for one
+%overlay before passing on to the next item in a stepping
+%environment. The optional argument $n$ tells \pf{HA-prosper} to wait
+%$n$ overlays before passing on to the next item. Example:
+%\begin{verbatim}
+%\overlays{5}{
+%\begin{slide}{xitemwait example}
+%  \begin{itemstep}
+%    \xitem 1
+%    \xitem 2
+%    \xitemwait[2]
+%    \xitem 3
+%  \end{itemstep}
+%\end{slide}
+%}
+%\end{verbatim}
+%This might come in handy to animate custom content using |\onSlide|
+%(see section~\ref{sec:onslide}) in dualslides
+%(section~\ref{sec:dualslide}) in combination with stepping
+%environments (section~\ref{sec:iestep}). Outside stepping
+%environments, the macro has no effect.
+%
+%\subsubsection{onSlide and OnSlide}\label{sec:onslide}
+%\DescribeMacro{\onSlide}
+%The macro
+%|\onSlide{overlays}{material}| displays |material| on the
+%overlays listed in |overlays|. This can be a comma delimited
+%list and the syntax explained in table~\ref{tab:osnot} can be
+%used ($x$ and $y$ are positive integers with $y\geq x$).

+%When used inside an |itemstep| or |enumstep| environment, there is
+%extra syntax available. This syntax follows the same rules as
+%explained in table~\ref{tab:osnot}, but now $x$ and $y$ can start
+%with a |+| sign. This sign can be used to animate content relative
+%to the preceding |\xitem| in an |itemstep| or |enumstep|
+%environment. Suppose that for instance the preceding |\xitem| of
+%|\onSlide{+1-+2}{...}| will be displayed on overlay 6. Then the
+%material of |\onSlide| will be displayed from overlay 7 to 8. Since
+%this construct is relative, it is very easy to add to or delete
+%items from the list without having to adapt all of the |\onSlide|
+%commands that you used. See another example below.
+%\begin{verbatim}
+%\overlays{4}{
+%\begin{slide}{onSlide example}
+%\begin{itemstep}
+%  \xitem item 1
+%  \xitem item 2
+%  \begin{itemize}
+%    \xitem item 3 \onSlide{+1-}{and item 4}
+%  \end{itemize}
+%  \xitemwait
+%  \xitem item 5
+%\end{itemstep}
+%\end{slide}
+%}
+%\end{verbatim}
+%
+%The |\onSlide| macro collects and generalizes all the
+%functionality of the \pf{prosper} macros |\onlySlide|,
+%|\untilSlide| and |\fromSlide|. This macro advances the
+%cursor position even if the material is not displayed. The stared
+%version |\onSlide*| does not advance the cursor position in
+%case the material is not displayed and collects the functionality
+%of the \pf{prosper} macros |\onlySlide*|, |\untilSlide*| and
+%|\fromSlide*|. Note that these macros can be nested into each
+%other, which allows for the creation of more parsimonious
+%structures (which will also become more complex). For instance,
+%\begin{verbatim}
+%\onSlide{-3,5-6,8,10-}{One}\onSlide{-2,6,8,10-}{Two}\onSlide{2,8,10-}{Three}
+%\end{verbatim}
+%and
+%\begin{verbatim}
+%\onSlide{-3,5-6,8,10-}{One\onSlide{-2,6-}{Two\onSlide{2,8-}{Three}}}
+%\end{verbatim}
+%produce the same output. The following example demonstrates the
+%difference between |\onSlide| and |\onSlide*|:
+%\begin{verbatim}
+%\onSlide{1}{One}\onSlide{2}{Two}\onSlide{3-}{Three}\par
+%\onSlide*{1}{One}\onSlide*{2}{Two}\onSlide*{3-}{Three}
+%\end{verbatim}
+%
+%\DescribeMacro{\OnSlide}
+%The macro |\OnSlide{overlays}| also accepts the same syntax as the
+%|\onSlide| macro and can be used to display or not all of the
+%following material on a slide after the |\OnSlide| macro. This macro
+%collects the functionality of the \pf{prosper} macros |\OnlySlide|,
+%|\UntilSlide| and |\FromSlide|.
+%Example:
+%\begin{verbatim}
+%\OnSlide{3-} All of this material will be displayed as from overlay 3.
+%\end{verbatim}
+%
+%\subsection{Numbering on overlays}\label{sec:numbering}
+%Mathieu Goutelle \cite{Mathieu} contributed a patch for the
+%|\overlays| macro which makes it possible to number equations,
+%tables and figures on overlays. This patch has been extended such
+%that you can also protect custom counters on overlays. For general
+%information about numbering, see your favorite \LaTeX\ book for
+%more information.
+%
+%The |counters| option for |\HAPsetup| (section~\ref{sec:globals})
+%can be used to list the counters that should be protected. For instance,
+%\begin{verbatim}
+%\newtheorem{mytheorem}{Theorem}
+%\newtheorem{myproof}{Proof}
+%\HAPsetup{counters={mytheorem,myproof}}
+%\end{verbatim}
+%in your preamble, will let you safely do
+%\begin{verbatim}
+%\overlays{3}{
+%\begin{slide}{Proof}
+%  \begin{myproof}
+%    Suppose that:
+%    \begin{equation}
+%      x^2+y^2=z^2
+%    \end{equation}
+%    then\dots
+%  \end{myproof}
+%\end{slide}
+%}
+%\end{verbatim}
+%The counters |figure|, |equation| and |table| are protected
+%on overlays by default. The |counters| option for |\HAPsetup|
+%lists the additional counters that should be protected. Notice that
+%the counter that you want to protect needs to exist when issuing
+%|\HAPsetup| to set the protected counters.
+%
+%\subsection{Portrait slides}\label{sec:portrait}
+%\DescribeSwitch{portrait}
+%If a template supports portrait slides, you can access these by
+%specifying the |portrait| option in the |\usepackage| command
+%like
+%\begin{verbatim}
+%\usepackage[toc,portrait,HA]{HA-prosper}.
+%\end{verbatim}
+%When requesting portrait slides, a template will give an error if
+%it does not support portrait slides. See
+%section~\ref{sec:supportt} for the templates that support portrait
+%slides. When using portrait slides, the |hlsections| option might
+%be useful for you, see section~\ref{sec:tochl}.
+%
+%\subsection{Notes}\label{sec:notes}
+%\DescribeEnv{notes}
+%The \pf{HA-prosper} package provides a way to make notes in
+%your presentation. To include notes in the presentation that go
+%with a slide, start a |notes| environment after this slide.
+%For instance
+%\begin{verbatim}
+%\begin{slide}{First slide}
+%...
+%\end{slide}
+%
+%\begin{notes}{Notes for the first slide}
+%These are the notes for the first slide.
+%\end{notes}
+%\end{verbatim}
+%
+%\DescribeSwitch{slidesonly}
+%\DescribeSwitch{notesonly}
+%\DescribeSwitch{notes}
+%An additional option in the |\usepackage| command provides a
+%way to control the printing of notes and slides. Include at most
+%one of the following options.
+%\begin{itemize}
+%\item |slidesonly|: produces the slides only. This is the
+%default option. Use this to create the presentation that you want
+%to project. \item |notesonly|: produces the notes only.
+%\item |notes|: includes the notes in the presentation.
+%\end{itemize}
+%For instance
+%\begin{verbatim}
+%\usepackage[toc,notesonly,HA]{HA-prosper}
+%\end{verbatim}
+%
+%\textbf{Note}: If you want the notes only, first run the
+%presentation at least once with the option `notes' to create
+%correct labels for the notes page numbers. Once that is done, run
+%the presentation with the `notesonly' option to create the
+%notes\footnote{In case you use landscape slides, do not forget to
+%put Auto-Rotation of pages to `Individually' if you are using the
+%Acrobat Distiller to create the PDF. `Collectively by File' will
+%rotate will rotate notes to landscape just like the slides.}.
+%
+%\subsection{Bibliography}\label{sec:bib}
+%\DescribeEnv{thebibliography}
+%\pf{HA-prosper} redefines the standard \pf{article}
+%|thebibliography| environment to suppress the creation of a section
+%heading and running headers. All other properties are maintained.
+%Now you can do either of the next two (depending whether you are
+%using BiB\TeX\ or not):
+%\begin{center}
+%\begin{tabular}{p{7cm}p{5cm}}
+%\begin{verbatim}
+%\begin{slide}{slide 1}
+%\cite{someone}
+%\end{slide}
+%\begin{slide}{References}
+%\begin{thebibliography}{1}
+%\bibitem{someone} Article of someone.
+%\end{thebibliography}
+%\end{slide}
+%\end{verbatim}&
+%\begin{verbatim}
+%\begin{slide}{slide 1}
+%\cite{someone}
+%\end{slide}
+%\begin{slide}{References}
+%\bibliography{YourBib}
+%\end{slide}
+%\end{verbatim}
+%\end{tabular}
+%\end{center}
+%In case you have a big reference list that you want to spread over
+%multiple slides, have a look at the packages \pf{natbib} and
+%\pf{bibentry} \cite{natbibCTAN}. Using both packages allows you to
+%do:
+%\begin{verbatim}
+%\begin{slide}{References (1)}
+%\nobibliography{YourBib}
+%\bibentry{someone1}
+%\bibentry{someone2}
+%\end{slide}
+%\begin{slide}{References (2)}
+%\bibentry{someone3}
+%\end{slide}
+%\end{verbatim}
+%Have a look at your favorite \LaTeX\ documentation for more
+%information about citations and bibliographies.
+%
+%\subsection{Bookmarks}\label{sec:bookmarks}
+%\pf{HA-prosper} nests bookmarks within sections created by
+%|\tsection| and |\tsection*| (see section~\ref{sec:section}) and
+%|\tsectionandpart| and |\tsectionandpart*| (see
+%section~\ref{sec:secandpart}). On the first pass of a document,
+%bookmarks will be written to disk and will be read on the second
+%pass to create the bookmarks. This is necessary to identify the
+%number of slide bookmarks that should be nested within section
+%bookmarks.
+%
+%Notice that the bookmark of a |\tsection| (or
+%|\tsection*|) points to the first slide within the section,
+%just as the toc link generated by this section. Furthermore, as
+%|\part| does not create a toc section, it does not create a
+%bookmarks section. This allows for creating both a flat table of
+%contents as well as a flat bookmarks list.
+%
+%The nesting of bookmarks in sections is fully compatible to the
+%nesting of bookmarks of overlays subordinate to the bookmarks of
+%the first overlay of a slide. Bookmarks created by section
+%commands are open and the bookmarks of slides are closed by
+%default. You can change the latter by issuing the \pf{prosper}
+%command |\collapsedBookmarksfalse| in the preamble of your
+%presentation.
+%
+%\subsection{Black slide}\label{sec:blslide}
+%\DescribeSwitch{blackslide}
+%The package option |blackslide| creates a completely black
+%slide as the first slide of the presentation. The PDF-file will
+%start at page 2 when opened, the first real slide, so the black
+%slide will not be revealed. The slide has an embedded target
+%called `blackslide'. In the top left corner of the black slide, a
+%black button is positioned which performs the Acrobat menu option
+%`GoBack' when clicking it. This allows to temporarily stop the
+%presentation (for instance, to write something at the blackboard)
+%by clicking a hyperlink that points to the target `blackslide'.
+%When the writing it done, click in the top left corner of the
+%black slide to continue the presentation.
+%
+%\subsection{Footers}\label{sec:footers} The
+%footers can be defined by the |\HAPsetup| command (see
+%section~\ref{sec:globals})\footnote{Notice that backward
+%compatibility is provided for \ci{LeftFoot} and
+%\ci{RightFoot}.}, for instance
+%\begin{verbatim}
+%\HAPsetup{lf={Left footer},rf={Right footer}}
+%\end{verbatim}
+%The default values of |lf| and |rf| are empty strings. The
+%slide number layout can be specified by the |sn| option. The
+%default value of |sn| is\footnote{\ci{thepage}
+%contains the number of the current slide, \ci{totalpages} inserts
+%the total number of slides in the presentation and
+%\ci{ifallPages} is a conditional from \pf{prosper} which is false
+%if the \pf{prosper} class option |nototal| is specified by the
+%user.}
+%\begin{verbatim}
+%{-~p.~\thepage\ifallPages/\totalpages\fi}
+%\end{verbatim}
+% which resembles the standard \pf{prosper} layout.
+%\pf{HA-prosper} adds a space in between the text specified by
+%|rf| and the text specified by |sn| to create the entire
+%right footer. Another example of the slide number layout could be
+%\begin{verbatim}
+%\HAPsetup{sn={slide~\#\thepage}}.
+%\end{verbatim}
+%
+%\subsection{e-mail, institution and the
+%and-command}\label{sec:eia}
+%\DescribeMacro{\author}
+%\DescribeMacro{\email}
+%\DescribeMacro{\institution}
+%\pf{HA-prosper} changes the behavior
+%of the \pf{prosper} commands |\email| and |\institution|.
+%The package does not anymore put them directly onto the title
+%page. Instead, you can use them inside the |\author| command to
+%use the fonts that the template specifies for the e-mail address
+%and the institution. This is done to offer support for the
+%|\and| command\footnote{This was not possible in the
+%construction used by \pf{prosper}.}. Example:
+%\begin{verbatim}
+%\author{%
+%  Me\\
+%  \institution{My institution}\\
+%  \email{My e-mail address}
+%  \and
+%  You\\
+%  \institution{Your institution}\\
+%  \email{Your e-mail address}
+%}
+%\end{verbatim}
+%
+%\clearpage\section{Style specific features} This section documents
+%several style specific features. Check table~\ref{tab:supportt} in
+%section~\ref{sec:supportt} to find which features are supported by
+%each template.
+%
+%\subsection{maketitle}\label{sec:mct}
+%\DescribeMacro{\maketitle}
+%This adapted command
+%replaces the usual |\maketitle| and takes care of defining
+%a title slide with a different layout as the first slide, include
+%the title on that slide and create the rest of the slides as
+%normal slides (unless specified differently by using for instance
+%another slide environment, see section~\ref{sec:wpe}).
+%
+%This command has the same options as the |slide| environment (see
+%section~\ref{sec:slide}. By default, the title slide will appear in
+%neither the bookmarks list nor the table of contents. You can change
+%this by specifying respectively the |bm| option and/or the |toc|
+%option (see section~\ref{sec:slide}).
+%
+%If the |\maketitle| feature is not supported by a style,
+%then the |\maketitle| uses a normal slide to display the
+%title on.
+%
+%\subsection{Wideslide and partslide}\label{sec:wpe}
+%\DescribeEnv{wideslide}
+%A |wideslide| produces a slide with an extended text area in case
+%you need to display very wide formulas or figures. In a lot of
+%templates, this means that the table of contents will not be
+%displayed on a wideslide.
+%
+%As a remark: the optional arguments possible for the
+%|\maketitle| (see section~\ref{sec:mct}) are also available
+%for the modified slide environments. So
+%\begin{verbatim}
+%\begin{wideslide}[toc=Toc slide title,trans=Replace]{Slide title}
+%...
+%\end{wideslide}
+%\end{verbatim}
+%creates a |wideslide| which does not have transition
+%effects itself and uses `Toc slide title' as the entry for the
+%(optional) table of contents. See section~\ref{sec:toc} for more
+%information about the optional table of contents.
+%
+%\DescribeEnv{partslide}
+%The |partslide| environment is available in some styles. This
+%environment uses a template which has been designed especially for
+%use with the |\part| (see section~\ref{sec:part}) and the
+%|\sectionandpart| commands (see section~\ref{sec:secandpart}).
+%
+%See section~\ref{sec:supportt} to find which styles support
+%|wideslide| or |partslide| environments.
+%
+%\subsection{Hidden navigation}\label{sec:navs} If you use Acrobat (Reader)
+%to project the slides, it is possible to embed hidden navigational
+%components. The navigational components are accessed by clicking
+%the logo on a slide (unless stated otherwise in style specific
+%documentation). These components are always hidden and hence
+%removing their definitions when you want to print the slides is
+%not necessary. Using |\HAPsetup| (see
+%section~\ref{sec:globals}), you can set the following
+%options\footnote{Notice that backward compatibility for
+%\ci{TitleSlideNav} and \ci{NormalSlideNav} is provided.}:
+%\begin{itemize}
+%\item |tsnav|\\
+%Navigation possibilities of the logo on the title slide.\\
+%For instance: |tsnav=FullScreen|: when starting the
+%presentation, you can make the presentation full screen by
+%clicking the logo.
+%
+%\item |nsnav|\\
+%Navigation possibilities on all other slides.\\
+%For instance: |nsnav=ShowBookmarks| or |nsnav=GoToPage|: the
+%former will provide a list of slide titles when viewing the
+%presentation in full screen mode. In this case, proper slide
+%titles might help you navigate your presentation. The latter will
+%show a menu where you can type the slide number of the slide that
+%you want to display.
+%\end{itemize}
+%
+%For more possibilities, see the documentation of the
+%\pf{hyperref} package.
+%

+%\pf{prosper} documentation. Table~\ref{tab:devfeats1} lists
+%additional features of \pf{HA-prosper} available to control the
+%layout, fonts and colors of your style. The controls in
+%table~\ref{tab:devfeats2} are \pf{HA-prosper} internals and should
+%only be used in style files. In between brackets you can find links
+%to sections explaining the related user interface commands. Do not
+%forget to take a look at existing styles since these are the ideal
+%starting point to create a new style.
+%Note that if you use |\HAP@NSNav| or |\HAP@TSNav| in a style, make

+%\subsection{Table of contents typesetting}
+%\pf{HA-prosper} uses the macros |\HAP@tocentry| and
+%|\HAP@hltocentry| to typeset table of contents entries. The latter
+%macro will be used in case the entry needs to be highlighted. By
+%default, \pf{HA-prosper} puts the toc entry at hand in a |\parbox|
+%to allow for multi-line toc entries. For |\HAP@hltoctext|, the
+%latter is inserted in a |\psframebox|. You can redefine the former
+%macros to typeset the table of contents for your style in a
+%different way. Use |\HAP@toctext| in your definitions. This will at
+%run time contain the entry at hand in the markup specified by either
+%|\HAP@tline|, |\HAP@tlineonly|, |\HAP@tsection| or
+%|\HAP@tsectiononly| depending on the type of table of contents and
+%the type of the entry. See for instance the |Fyma| style for an
+%alternative table of contents markup. See further
+%table~\ref{tab:tocmarkup} for other macros related to typesetting
+%the table of contents and section~\ref{sec:toc} for more information

+%Note that the macros |\HAP@hcolor|, |\HAP@htcolor|, |\HAP@twidth|
+%and |\HAP@tborder| are only used in the default definitions of
+%|\HAP@tocentry| and |\HAP@hltocentry|. If you decide to redefine the
+%latter two macros, defining and using the former four might not be
+%necessary. The default toc typesetting uses these macros to provide
+%an easy way for style designers to tweak the default markup of the
+%table of contents.
+%
+%\subsection{Reserved commands}
+%\pf{HA-prosper} knows a couple of reserved commands. If these
+%commands are defined by a style, they will be used by
+%\pf{HA-prosper} to create new slide environments. See
+%table~\ref{tab:reserved}.
+%
+%\begin{table}[ht]
+%\caption{Reserved commands in \pf{HA-prosper}.} \label{tab:reserved}
+%\makebox[\textwidth][r]{
+%\begin{tabular}{d}\hline\hline
+%\ci{HAPR@normalSlide}&Should contain the layout
+%of a standard slide.\\\hline
+%\ci{HAPR@wideSlide}&Should contain the layout of a
+%wide slide; used for |wideslide| environment (\ref{sec:wpe}).\\\hline
+%\ci{HAPR@partSlide}&Should contain the layout of a
+%part slide; used for |partslide| environment (\ref{sec:wpe}).\\\hline
+%\ci{HAPR@titleSlide}&Should contain the layout of a
+%title slide; used to create title slide,\\
+%&which will be embedded in the \ci{maketitle} command (\ref{sec:mct}).\\\hline
+%\hline
+%\end{tabular}}
+%\end{table}
+%
+%Note that |\HAPR@normalSlide| is used to switch back to after
+%creating a special slide environment like |wideslide|. If this
+%command has not been defined in your style, then \pf{HA-prosper}
+%will not be able to define the environments mentioned in
+%section~\ref{sec:wpe} for you. As a last note: don't forget the
+%power of the \pf{PSTricks} package for designing styles.
+%
+%\clearpage\section{Miscellaneous issues}
+%
+%\subsection{Examples}\label{sec:examples}
+%Examples that use the \pf{HA-prosper} package are contained in the
+%|HAPIntroduction.tex|, |HAPBigtest.tex| and |HAPDualslide.tex|
+%files in this distribution. The examples assume that you have the
+%|HA| style. More examples can be found at the \pf{HA-prosper} website
+%\cite{HA-prosper}.
+%
+%Do not forget to take a look at the documentation of the
+%\pf{prosper} class, the \pf{hyperref} package and the
+%\pf{PSTricks} package to fully understand the possibilities of
+%slides created by \pf{HA-prosper}.
+%
+%\subsection{Required packages}\label{sec:req}
+%The most important requirements of the \pf{prosper} class are:
+%\begin{multicols}{2}
+%\begin{itemize}\setlength{\itemsep}{0pt}
+%\item \pf{seminar},
+%\item \pf{hyperref},
+%\item \pf{pstricks},
+%\item \pf{graphicx}.
+%\end{itemize}
+%\end{multicols}
+%The most important requirements of the \pf{HA-prosper} package
+%are:
+%\begin{multicols}{2}\raggedright
+%\begin{itemize}\setlength{\itemsep}{0pt}
+%\item \pf{prosper} (|prosper.cls| version 1.24),
+%\item \pf{xkeyval} \cite{xkeyvalCTAN},
+%\item \pf{xcomment},
+%\item \pf{verbatim}.
+%\end{itemize}
+%\end{multicols}
+%
+%\subsection{Resulting PDF}\label{sec:result}
+%The PDF produced by PS2PDF (GhostScript) is usually very big.
+%Unfortunately, it includes a copy of the logos on the slides every
+%time they appear. In case this logo is a rendered picture, the PDF
+%will become very big. There is not much you can do about that.
+%However, you can compress a generic presentation PDF file very
+%much (often even to 10\% of the original size) using for instance
+%WinZip. And you could of course delete the logo or replace it by a
+%non-rendered picture, for instance created by \pf{PSTricks}, see
+%the \pf{PSTricks} website \cite{PSTricks}. Compare for example
+%the |HA| style and the |Lakar| style.
+%
+%Another possibility is to use `Reduce file size' in the file menu
+%of Acrobat (available from version 6). You can also use the PDF
+%Optimizer in this version of Acrobat (Tools - PDF Optimizer).
+%Using this option, you can compress the pictures inside the
+%presentation and make the presentation considerably smaller. Hint:
+%do not use JPEG or JPEG2000 for the compression of images. Even at
+%the highest level of quality, this produces poor results for
+%projecting purposes. Instead, use the ZIP compression. Also, do
+%not downsize the resolution lower than 300 pixels per inch (for
+%retaining printing quality).
+%
+%However, to get the most efficient PDF document, use the Acrobat
+%Distiller to convert the PS file into a PDF file. Do not forget to
+%include the `distiller' option in the document class in this case
+%(see section~\ref{sec:compile}).
+%

+%A lot of thanks go Mathieu Goutelle \cite{Mathieu}, Herbert Vo\ss\
+%\cite{Herbert}, Murali Krishna Ganapathy \cite{Murali} and Laurent
+%Jacques for great help, code contributions and/or ideas for improvements.
+%\end{itemize}
+%
+%\subsection{Questions}\label{sec:questions}
+%If you have questions, please first consult the documentation of
+%the package that could possibly answer your question. Probably,
+%you can find the answer in the documentation of either the
+%\pf{HA-prosper} package, \pf{prosper} class, the \pf{hyperref}
+%package or the \pf{PSTricks} package. Also have a look at
+%WikiProsper \cite{WikiProsper} for a \pf{prosper} FAQ,
+%\pf{prosper} open questions, known \pf{prosper} bugs,
+%etcetera.
+%
+%If you cannot solve the problem yourself, or if you have comments or
+%requests for additional features, you may try to post a message to
+%the \pf{HA-prosper} mailinglist \cite{HAprospermaillist}. Do not
+%forget to include a \emph{minimal} example when you want help with
+%an error message.
+%
+%The use of the mailinglist will be supported as long as possible,
+%but as stated in section~\ref{sec:newclass} most effort will be done
+%to help \pf{powerdot} users and the \pf{HA-prosper} mailinglist may
+%disappear over time.

+%\subsection{Version history}
+%This section lists the main changes in this package as from
+%version 3.5. Note that each version change also contains solutions
+%to known (minor) bugs and improvements in programming and user
+%interface.
+%
+%\begin{itemize}
+%\item[\fbox{3.5}] Solved a bug with toc entries in combination with
+%highlighting. This bug was mainly caused
+%by the \pf{keyval} package not undefining variables when they are
+%not used. Thanks to Mathieu Goutelle for the help; added support
+%for the |\part| command. Made \pf{HA-prosper} load slide
+%style definitions itself at the final stage; changed style names
+%to |HAP[name].sty| to identify \pf{HA-prosper} style
+%definitions from \pf{prosper} style definitions; made
+%\pf{HA-prosper} undefine |\slidetitle| before loading the
+%style definitions;
+%
+%\item[\fbox{3.6}] Improved writing of toc entries; solved an
+%inconsistency in writing definitions between |seminar| and
+%|latex.ltx|; introduced |\section| and
+%|\sectionandpart|; completely changed |notes| environment,
+%not using |seminar| note constructions anymore; added support
+%for |\and| in |\author|; added |\fontToc|;
+%\begin{itemize}
+%\item[\fbox{3.61}] Removed redundant grouping;
+%\item[\fbox{3.62}] Adapted writing definitions a bit to be more consistent with
+%|seminar|;
+%\end{itemize}
+%
+%\item[\fbox{3.7}] Prepared \pf{HA-prosper} for compatibility to the
+%|prosper preview| class \cite{ppr-prv}; integrated specific
+%style features into \pf{HA-prosper}; recoded |\figureitem|
+%command; renamed |\section| to |\tsection|,
+%|\sectionandpart| to |\tsectionandpart| to provide
+%compatibility to for instance |\bibliography|; restructured
+%\pf{HA-prosper} internals;
+%\begin{itemize}
+%\item[\fbox{3.71}] Solved a small bug writing final toc entry AtEndDocument;
+%added |TCS| style by Chris Ellison.
+%\end{itemize}
+%
+%\item[\fbox{3.8}] Added |\tsection*|, |\tsectionandpart*| and
+%nesting of bookmarks; created |\dualslide|; added
+%|\hiddenitem|, |\putfigure|, |\figureitem| and
+%|\putfigureitem|. Revised the documentation; revised the
+%examples; added the |\dualslide| example; revised the styles.
+%
+%\item[\fbox{3.9}] Deleted |\putfigureitem| and |\figureitem|
+%and replaced |\putfigure| by the more general |\topbl|;
+%improved positioning of bottom text when using |\dualslide|;
+%added |indent| option for |\dualslide|; added support for a
+%split toc; added package option |hlsections|; added package
+%option |blackslide|; solved a bug occurring when
+%|\tsectionandpart| was used to create the last slide; added
+%|enumstep|; made it possible to nest |itemstep| and
+%|enumstep| environments; added |\HAPsetup|, yet only used
+%for stepping environments.
+%
+%\item[\fbox{4.0}] Changed to |.dtx| format and wrote code
+%documentation. Added slide options |bm| and |sound|. Added
+%default behavior of stepping environments with the |ps2pdf|
+%\pf{prosper} option to be type 1, namely all active. Changed
+%bookmarking process to a system that allows for deletion of
+%bookmarks. Added global control of features through
+%|HA-prosper.cfg|. Added |Aggie| style by Jack Stalnaker.
+%Made some code more efficient. Added entrance point for
+%\pf{ppr-prv} to make redefining macros easier for that class.
+%Solved a bug in combination with loading \pf{babel}. Added
+%|\onSlide| and |\OnSlide|.
+%
+%\item[\fbox{4.1}] Moved documentation to |.dtx| file. Added
+%package option |counters|. Restored original |\item| and
+%created |\xitem|. Changed |\hiddenitem| to |\xitemwait|
+%which is a bit more general. Removed a bug in |\onSlide|.
+%Rewrote a lot of code. Made \pf{HA-prosper} use \pf{xkeyval}.
+%Changed |emptyslide| into more |partslide|. Added |Fyma| style
+%by Laurent Jacques.
+%
+%\begin{itemize}
+%\item[\fbox{4.11}] Corrected small bug in \pf{ppr-prv} compatibility

+%\end{itemize}
+%
+%\item[\fbox{4.2}] Improved table of contents typesetting. Added
+%|\xitem<n>|. Added |thebibliography| environment. Improved
+%positioning of the slide title in the styles. Added handle for state
+%of list items. Updated styles. Added |TCSgrad| and |TCSTealBlue|
+%styles by Chris Ellison. Added extra syntax for |\onSlide| and
+%|\OnSlide| to make displaying material relative to the preceding
+%|\xitem|.
+%
+%\begin{itemize}
+%\item[\fbox{4.21}] Added |Capsules| and |Ciment| styles by Mathieu
+%Goutelle. Updated for \pf{xkeyval} version 1.4.

+% \DescribeEnv{NewSlideStyle}
+% This environment needs to be redefined to be able to remember
+% the anchor and the position of the main text box on slides.
+% The original comes from \pf{prosper}.
+%    \begin{macrocode}

+  \gdef\HAP@current@pos{#3}%
+}
+%    \end{macrocode}
+% \DescribeMacro{\protected@write}
+% |Seminar| uses a somewhat different writing macro than |latex.ltx|. The
+% |seminar| definition gets inserted at every |\begin{slide}| and is local.
+% To assure
+% that this writing definition is also used in between slides (e.g.
+% for |\tsection|) we need to redefine it once. The main difference
+% is in the use of |\immediate| by |seminar| while this is not used
+% by |latex.ltx|. This difference would, without this definition, create mixing errors.
+%    \begin{macrocode}
+\def\protected@write#1#2#3{%

+  \if@nobreak\ifvmode\nobreak\fi\fi
+}
+%    \end{macrocode}
+% \subsubsection{Support for notes}
+% Notes are created on slides, but with an adapted template. We start
+% with defining some counters. The first is used to count the number
+% of notes with a particular slide.
+%    \begin{macrocode}
+\newcounter{HAP@notes@slide}
+%    \end{macrocode}
+% This counter is used to count the total number of notes.
+%    \begin{macrocode}
+\newcounter{HAP@notes@true}
+%    \end{macrocode}
+% And this is a temp counter to remember the slide that the notes
+% belong to.
+%    \begin{macrocode}
+\newcounter{HAP@notes@temp}
+%    \end{macrocode}
+% The template to be used by notes.
+%    \begin{macrocode}
+\def\HAP@notes@frame#1{#1}
+\ifHAP@portrait
+  \def\HAP@notes@template{\NewSlideStyle[8.8cm]{tl}{-0.6,4}{HAP@notes@frame}}
+\else
+  \def\HAP@notes@template{\NewSlideStyle[8.8cm]{tl}{1.2,4}{HAP@notes@frame}}
+\fi
+%    \end{macrocode}
+% Start writing a file to store notes page numbers.
+%    \begin{macrocode}
+\ifHAP@notes
+  \newwrite\HAP@notesout\openout\HAP@notesout\jobname.not\relax
+\fi
+%    \end{macrocode}
+% When notes only, use saved page numbers.
+%    \begin{macrocode}
+\ifHAP@notesonly
+  \begingroup\InputIfFileExists{\jobname.not}{}{}\endgroup
+  \xcomment{notes}
+\fi
+%    \end{macrocode}
+% \begin{environment}{notes}
+% This macro defines the notes environment.
+%    \begin{macrocode}
+\def\notes#1{%
+  \ifHAP@slidesonly\comment\else
+%    \end{macrocode}
+% Count the number of notes with a particular slide. If we are still
+% on the same slide, but have a new notes slide, add one to the counter
+% for notes slides, otherwise reset that counter.
+%    \begin{macrocode}
+    \ifnum\value{slide}=\value{HAP@notes@temp}
+      \stepcounter{HAP@notes@slide}%
+    \else
+      \setcounter{HAP@notes@slide}{1}%
+    \fi
+%    \end{macrocode}
+% Set the temp counter to the current slide to remember to which slide
+% the notes belong.
+%    \begin{macrocode}
+    \setcounter{HAP@notes@temp}{\value{slide}}%
+    \stepcounter{HAP@notes@true}%
+%    \end{macrocode}
+% If not notes only, then the notes page numbers get written to disk
+% by using labels. This makes sure that, when using the option |notesonly|
+% at the first pass of the presentation, there are no errors, only warnings.
+%    \begin{macrocode}
+    \ifHAP@notesonly\else
+      \protected@write\HAP@notesout{}{\string\newlabel{notes@\number\c@HAP@notes@true}%
+      {{}{\number\c@HAP@notes@temp-\number\c@HAP@notes@slide}{\relax }{}{}}}%
+    \fi
+%    \end{macrocode}
+% Save anchor and position of the text box of the previous slide.
+%    \begin{macrocode}
+    \xdef\HAP@temp@anchor{\HAP@current@anchor}%
+    \xdef\HAP@temp@pos{\HAP@current@pos}%
+%    \end{macrocode}
+% Start notes on a portrait slide environment.
+%    \begin{macrocode}
+    \HAP@notes@template\HAP@portraittrue
+    \begin{slide}[toc=,bm=,trans=Replace]{HAP@notitle}\black
+    \rput[tl](0,1.5){\fontTitle{\black#1}}%
+%    \end{macrocode}
+% Position the notes number using |PSTricks|.
+%    \begin{macrocode}
+    \ifHAP@notesonly
+      \rput[tc](4.4,-10.5){\realpageref{notes@\number\c@HAP@notes@true}}%
+    \else
+      \rput[tc](4.4,-10.5){\number\c@HAP@notes@temp-\number\c@HAP@notes@slide}%
+    \fi
+  \fi
+}
+%    \end{macrocode}
+% Closing the notes environment and restoring the text box position
+% and anchor to its original values to be used by the next slide (or note).
+%    \begin{macrocode}

+% macros of \pf{prosper}: |\fromSlide|, |\FromSlide|, |\untilSlide|,
+% |\UntilSlide|, |\onlySlide| and |\OnlySlide|. The macros are more
+% or less based on these \pf{prosper} macros, but are more general
+% and replace all those macros. We start with some counters
+% and an if necessary to determine whether material should be
+% displayed on the current overlay or not.
+%    \begin{macrocode}

+%    \end{macrocode}
+% \begin{macro}{\onSlide}
+% \HAPcmd{\ci{onSlide}\marg{overlays}\marg{mat}}
+% This macro allows for
+% comma seperated inputs like |\onSlide{-2,4,6-8,10-}|. |\onSlide|
+% has a starred version which doesn't move the cursor in case the
+% material is not displayed on the slide.
+%    \begin{macrocode}
+\def\onSlide{\@ifstar{\HAP@onSlide{1}}{\HAP@onSlide{0}}}
+\long\def\HAP@onSlide#1#2{%
+%    \end{macrocode}
+% Split the comma seperated list into parts to be read by |\HAP@read|.
+% The macro will set |\ifHAP@displayMat| which tells us to display
+% the material on the current slide or not.
+%    \begin{macrocode}

+  \let\HAP@next\@gobble

+% We should display it.

+% Reset |\ifHAP@displayMat| for future use.
+%    \begin{macrocode}

+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\OnSlide}
+% \HAPcmd{\ci{OnSlide}\marg{overlays}}
+% This macro also allows for comma seperated lists, but takes only
+% one argument and masks or not all the following material.
+%    \begin{macrocode}
+\def\OnSlide#1{%

+% We should display the following material; don't hide it.
+%    \begin{macrocode}

+%    \end{macrocode}
+% Reset |\ifHAP@displayMat|.
+%    \begin{macrocode}

+% \begin{macro}{\HAP@read}
+% This macro reads the argument between two commas supplied by |\HAP@split|.
+% We distinct 4 cases: $x$, -$x$, $x$- and $x$-$y$ where $x$ and $y$ are positive
+% integers with $y\geq x$. We will not check the argument for specification;
+% the responsibility is with the user. The macro first sets a range from
+% the inputs, then runs over this range to check wether the current
+% overlay is inside the range and hence material should be displayed.
