%\begin{abstract}\noindent
%\pf{powerdot} is a presentation class for \LaTeX\ that allows for
%the quick and easy development of professional presentations. It
%comes with many tools that enhance presentations and aid the
%presenter. Examples are automatic overlays, personal notes and a
%handout mode. To view a presentation, DVI, PS or PDF output can be
%used. A powerful template system is available to easily develop new
%styles. A \LyX\ layout file is provided.

%\section{Introduction}\label{sec:intro}
%This class gives you the possibility to easily create professionally
%looking slides. The class is designed to make the development of
%presentations as simple as possible so that you can concentrate on
%the actual content instead of keeping yourself busy with technical
%details. Of course, some knowledge of \LaTeX\ is still required
%though.
%
%This class builds on and extends the \pf{prosper} class
%\cite{prosper} and the \pf{HA-prosper} package \cite{HA-prosper}.
%The \pf{HA-prosper} package was initially intended to extend
%\pf{prosper} and correct some bugs and problems of that class. As
%developments on that package progressed, it was found that
%unfortunately, not all of the problems could be overcome with the
%package. That discovery was the start of a new project set up to
%make a new class to replace the \pf{prosper} plus \pf{HA-prosper}
%combination. You're currently reading the result of that project.
%
%The remainder of this section will be devoted to giving a feel of
%what the \pf{powerdot} presentation source looks like and giving an
%overview of this documentation.
%
%The document structure of a presentation is always the same. You can
%find it in the example below.
%
%\begin{example}
% \documentclass[<class options>]{powerdot}
% \pdsetup{<presentation options>}
% \begin{document}
%   \begin{slide}{a slide}
%     Contents of the slide.
%   \end{slide}
%   \section{first section}
%   \begin{slide}[<slide options>]{another slide}
%     Contents of the slide.
%   \end{slide}
%   \begin{note}{personal note}
%     The note.
%   \end{note}
% \end{document}
%\end{example}
%
%There are several elements that define the document structure. First
%of all, the class accepts some class options that control the output
%of the class, for instance, paper type and style. These class
%options will be discussed in section~\ref{sec:classopts}. Then there
%are presentation specific options which control some of the elements
%of the presentation globally, for instance, the footers. These will
%be discussed in section~\ref{sec:pdsetup}.
%
%Once the setup has been decided on, you can use the slide
%environment to produce slides (see section~\ref{sec:slides}) and the
%note environment to produce notes that go with the slides (see
%section~\ref{sec:notes}). You can use overlays to display material
%in steps. This is described in section~\ref{sec:overlays}. The
%|\section| command provides a way to structure your presentation.
%This is discussed in section~\ref{sec:structure}.
%Section~\ref{sec:styles} will show an overview of the styles that
%come with this class and the characteristics of each style.
%Section~\ref{sec:compiling} will tell you more about how to produce
%output. This section contains important information on required
%packages.
%
%Section~\ref{sec:writestyle} is mostly interesting for people that
%want to develop their own style for this class or want to modify an
%existing style. Section~\ref{sec:lyx} explains how \LyX\
%\cite{LyXWeb} can be used to create \pf{powerdot} presentations.
%This documentation concludes with a section devoted to questions
%(section~\ref{sec:questions}), like `Where can I find examples?'. It
%also tells you where to turn to in case your questions are still not
%solved.
%
%\section{Setting up the presentation}\label{sec:setup}
%This section will describe all options that are available to control
%the output of the presentation and the looks of it.
%
%\subsection{Document class options}\label{sec:classopts} We will
%start with the class options that are typed in the |\documentclass|
%command as a comma-separated list. For each option, the preset
%value\footnote{The value that will be used when you don't use the
%option.} will be mentioned in the description. This is the value
%that will be used if you decide to not give a value to the option or
%not use the option at all.
%
%\DescribeOption{mode}
%This options controls the kind of output that we want to produce.
%The preset value is |present|.
%\begin{description}
%\item\option{mode=present}\\
%This mode is used when you want to create the actual presentation. It
%will enable overlays and transition effects. You can read more about
%overlays in section~\ref{sec:overlays}.
%\item\option{mode=print}\\
%This mode can be used when printing the slides including their visual
%markup, but without any overlay or transition effects.
%\item\option{mode=handout}\\
%This mode will produce a black and white overview of your slides that
%can be used to make personal notes on, for distribution to students,
%a personal guide during your talk, etcetera.
%\begin{description}
%\item\option{nohandoutpagebreaks}\\
%By default, the handout mode produces a document with two slides per
%page. If you want to fit more slides on a page, specify this option
%in the |\documentclass| command and \pf{powerdot} will let \LaTeX\
%decide on the places to insert a page break, namely when a page is
%full.
%\item\option{nohandoutframes}\\
%By default, the handout frames the slides. This option will remove
%the frames around slides on handouts.
%\end{description}
%\end{description}
%
%\DescribeOption{paper} This option has three possible values. The
%preset value is |screen|.
%\begin{description}
%\item\option{paper=screen}\\
%This is a special format with screen optimized ratio (4/3). The
%actual page dimensions will be 8.25 inch by 11 inch. This paper format
%is not available for print or handout mode. In these modes, \pf{powerdot}
%will switch to a4 paper and put a warning that it did this in the
%log file of your presentation.
%\item\option{paper=a4paper}\\
%A4 paper will be used for the presentation or handout.
%\item\option{paper=letterpaper}\\
%Letter size paper will be used.
%\item\option{paper=smartboard}\\
%For presentation on a smartboard (widescreen).
%\end{description}
%Some important information with respect to paper size, compiling and
%viewing presentations is available in section~\ref{sec:compiling}.
%
%\DescribeOption{orient} This controls the orientation of the
%presentation. The preset value is |landscape|.
%\begin{description}
%\item\option{orient=landscape}\\
%The presentation will be in landscape format. This value is not
%available in handout mode. In that mode, \pf{powerdot} will switch
%to portrait orientation and will warn you about this in the log
%file.
%\item\option{orient=portrait}\\ This produces slides in portrait
%format. Notice that not all styles support portrait orientation. Please
%refer to section~\ref{sec:styles} for information about which styles
%do support the portrait orientation.
%\end{description}
%
%\DescribeOption{display} This controls the production of slides and
%notes. The preset value is |slides|.
%\begin{description}
%\item\option{display=slides}\\
%This will only typeset the slides in your presentation.
%\item\option{display=slidesnotes}\\
%This will typeset both the slides and the notes in your
%presentation. See also section~\ref{sec:notes} for more information
%about notes.
%\item\option{display=notes}\\
%This will typeset the notes only.
%\end{description}
%
%Here are some more options to control the output.
%\begin{description}
%\item\DescribeOption{size}\option{size}\\
%This is the size of the normal text font in points. Possible values
%are 8pt, 9pt, 10pt, 11pt, 12pt, 14pt, 17pt and 20pt and the preset
%value is 11pt.\footnote{Note that sizes other than 10pt, 11pt and
%12pt are non-standard and it is assumed that you have the
%\pf{extsizes} bundle \cite{extsizes} installed, which provides these
%sizes.}
%\item\DescribeOption{style}\option{style}\\
%This controls the style to be loaded for the presentation. By
%default, the \pf{default} style will be loaded. For more styles, see
%section~\ref{sec:styles}.
%\item\DescribeOption{fleqn}\option{fleqn}\\
%This option makes equations flushed left. It does the same as the
%equally named option for the article class.
%\item\DescribeOption{leqno}\option{leqno}\\
%Put equation numbers at the left. Also the same as in the article
%class.
%\item\DescribeOption{nopsheader}\option{nopsheader}\\
%By default, \pf{powerdot} will write a postscript command to the ps
%file to make sure that post processors like ps2pdf know which paper
%to use without the need to specify it on the command line. See also
%section~\ref{sec:compiling}. If you experience problems with post
%processing or printing or you want to specify the paper size in the
%post processing steps yourself, use this option.
%\item\DescribeOption{hlentries}\option{hlentries}\\
%This highlights table of contents entries when the entry matches
%with the current slide and its preset value is |true|. See also
%section~\ref{sec:structure}. If you don't want highlighting of table
%of contents entries (for instance in print mode), use
%|hlentries=false|.
%\item\DescribeOption{hlsections}\option{hlsections}\\
%This highlights table of contents sections when the section matches
%with the current section in the presentation and is preset to |false|.
%See also section~\ref{sec:structure}. Specifying this
%option turns highlighting of sections on. This could be useful when
%you are using a style that implements a split table of contents.
%\item\DescribeOption{pauseslide}\option{pauseslide}\\
%This option inserts a black slide in the presentation on page 1 and
%will automatically advance to page 2 when opening the presentation
%in a PDF viewer like Acrobat (Reader). The option also inserts a
%link behind every slide or section title that brings you to the
%black slide when clicked. When you click anywhere in the black
%slide, you will go back to the originating slide. This option can be
%used to temporarily pause a presentation, for instance, to do a
%proof on the black board. Optionally, a color can be supplied, for instance,
%|pauseslide=white| to have a pause on a white screen.
%\item\DescribeOptions{clock}\option{clock}\\
%This displays a small digital clock on slides which you can use to
%check the time left for your presentation.
%\end{description}
%
%Here is an example of a |\documentclass| command.
%\begin{example}
% \documentclass[
%   size=12pt,
%   paper=screen,
%   mode=present,
%   display=slidesnotes,
%   style=tycja,
%   nohandoutpagebreaks,
%   pauseslide,
%   fleqn
% ]{powerdot}
%\end{example}
%This example sets up a presentation in \pf{tycja} style, with a black
%slide, normal size 12 points and flushed left equations.
%\begin{example}
% \documentclass[
%   size=12pt,
%   paper=letterpaper,
%   mode=handout,
%   display=slidesnotes,
%   style=tycja,
%   nohandoutpagebreaks,
%   pauseslide,
%   fleqn
% ]{powerdot}
%\end{example}
%Changing the |paper| and |mode| options, now produces a handout with
%possibly more than two slides per page due to the |nohandoutpagebreaks|
%option.
%
%\subsection{Setup options}\label{sec:pdsetup}
%\DescribeMacro{\pdsetup}
%There are several extra options that can help customizing your
%presentation. These options are not available via the
%|\documentclass| command. This has a technical reason.\footnote{The
%interested reader is referred to the section about the \pf{xkvltxp}
%package in the \pf{xkeyval} package documentation \cite{xkeyval}.}
%We distinguish two types of options. Options that can only be set
%globally (acting for the entire presentation) using the |\pdsetup|
%command and options that can be accessed both globally (via
%|\pdsetup|) and locally (via slide environments, see section~\ref{sec:slides}).
%
%\subsubsection{Global options}\label{sec:gopts}
%This section describes options that can only be used globally in the
%preamble of your presentation via the |\pdsetup| command.
%\begin{description}
%\item\DescribeOption{palette}\option{palette}\\
%This specifies the palette to be used. A palette is a set of colors
%defined by a style. To find out which palettes are defined by each
%style, see section~\ref{sec:styles}.
%\item\DescribeOption{theslide}\option{theslide}\\
%This option controls how the slide number appears on the slide. This
%is preset to the value |\arabic{slide}~/~\pageref*{lastslide}|,
%which could appear like |5/22|. Notice that the |\arabic{slide}|
%typesets the number of the current slide and that
%|\pageref*{lastslide}| typesets the number of the last
%slide.\footnote{We use the starred version of \cs{pageref} which is
%defined by \pf{hyperref} and does not create a link to the page that
%it is referring to.}
%\item\DescribeOption{thenote}\option{thenote}\\
%This is similar to the |theslide| option, but typesets the slide
%numbers of notes. The preset value is
%|note~\arabic{note}~of~slide~\arabic{slide}| and |\arabic{note}|
%here typesets the number of the current note that goes with the
%current slide. This could appear like |note 2 of slide 7|.
%\item\DescribeOption{counters}\option{counters}\\
%The |counters| option lists counters that you might want to protect
%on overlays. As material on overlays (see
%section~\ref{sec:overlays}) is processed multiple times, also
%\LaTeX\ counters, like the |equation| counter, might be increased
%too often. To avoid that your equations get different numbers on
%every overlay, use this option. The |equation|, |table|, |figure|,
%|footnote| and |mpfootnote| counters are already protected for you.
%If you use extra counters, for instance for theorems, list them in
%this option. Example:
%\begin{example}
% counters={theorem,lemma}
%\end{example}
%\item\DescribeOption{list}\option{list}\\
%This option takes a list of options that will be passed on to the
%\pf{enumitem} package that controls the layout of lists created by
%the |enumerate| and |itemize| environments. Example:
%\begin{example}
% list={labelsep=1em,leftmargin=*,itemsep=0pt,topsep=5pt,parsep=0pt}
%\end{example}
%See for more information on controlling the layout of lists the
%\pf{enumitem} package \cite{enumitem}.
%\item\DescribeOptions{enumerate,itemize}\option{enumerate,itemize}\\
%As the |list| option, but only control |enumerate| and |itemize|
%environments respectively.
%\item\DescribeOption{clockformat}\option{clockformat}\\
%This option specifies the format of the clock. The format is set using
%Acrobat's |util.printd| function.\footnote{For a complete listing of
%allowable formats, consult the \textit{Acrobat JavaScript Scripting
%Reference}\cite{javascript}.} The default value is |HH:MM:ss|, which
%shows a 00-23 hour, 00-59 minute, 00-59 second clock. Example:
%\begin{example}
% clockformat=h:MM tt
%\end{example}
%The above setting will display a 1-12 hour, 00-59 minute, am/pm clock.
%That is, the clock might show |5:53 pm|.
%\item\DescribeOption{clockrefresh}\option{clockrefresh}\\
%This option should be a number which specifies how often
%the clock is refreshed in milliseconds. The default behavior is to refresh
%the clock every second. Thus, the default value is 1000. Notice, if the
%|clockformat| is such that seconds are not shown, then it makes no sense
%to update that clock every second.  A corresponding example:
%\begin{example}
% clockrefresh=60000
%\end{example}
%The interpretation of this is that the clock will be updated every minute.

%\subsubsection{Global and local options}\label{sec:glopts}
%This section describes options that can be used both globally via
%|\pdsetup| and locally via slide environments (see section~\ref{sec:slides}).
%\begin{description}
%\item\DescribeOptions{lf,cf,rf}\option{lf,cf,rf}\\
%This determines the content of the left, center and right footers.
%These are preset to empty.
%\item\DescribeOption{trans}\option{trans}\\
%This option sets the default transition effect to be used in the
%presentation. These transition effects only work after compiling the
%presentation to PDF format. See also section~\ref{sec:compiling}.
%The following transition effects are supported: |Split|, |Blinds|,
%|Box|, |Wipe|, |Dissolve|, |Glitter| and |Replace|. When you are using
%a viewer that understands PDF 1.5, you can also use |Fly|, |Push|,
%|Cover|, |Uncover| or |Fade|. It is important to notice that most
%viewers are case sensitive, so, for instance, |box| will not work.
%
%The preset effect is |Replace| which just replaces one slide with
%another when browsing the slides. Note that some PDF viewers (like
%Acrobat Reader 5 and higher) only produce the transition effect in
%full screen mode. If you want to use a custom transition effect that
%is not listed in the list above (for instance, a wipe effect with a
%custom wipe direction), then that is possible. However,
%\pf{powerdot} will put a warning in your log file that the effect
%that you have chosen, might not work in the PDF viewer. Here is an
%example that does work.
%\begin{example}
% trans=Wipe /Di 0
%\end{example}
%In Acrobat (Reader), this wipes from left to right instead of the
%default top to bottom. For more information, see a PDF Reference
%Manual.
%\item\DescribeOption{method}\option{method}\\
%This option can be used when a slide contains special material that
%does not get treated in the `usual' way by \LaTeX. Verbatim material
%is an example of this. Possible values are |normal| (the preset value),
%|direct| and |file|. We will come back to this option in detail in
%section~\ref{sec:verbatim}.
%\item\DescribeOptions{logohook,logopos,logocmd}\option{logohook,logopos,logocmd}\\
%If |logopos| is specified, a logo defined by the value of the
%|logocmd| option will be put on slides. The position can be
%specified relative to the width and height of the slide. |{0,0}| is
%the lower left corner of the paper and |{\slidewidth,\slideheight}|
%is the upper right corner. For positioning the logo, the |\rput|
%command of \pf{pstricks} \cite{PSTricksWeb,PSTricks} is used. This
%command also allows to specify the point of the logo that should be
%positioned there. This point can be entered via the |logohook|
%option and can take the values |tl|, |t|, |tr|, |r|, |Br|, |br|,
%|b|, |bl|, |Bl|, |l|, |B| and |c|. For more information about
%|\rput|, consult the \pf{pstricks} documentation. Here is an example
%that integrates the flower of the \pf{default} style into the
%\pf{husky} style.
%\begin{example}
% \documentclass[style=husky]{powerdot}
% \pdsetup{
%   logohook=t,
%   logopos={.088\slidewidth,.99\slideheight},
%   logocmd={\includegraphics[height=.08\slideheight]{powerdot-default.ps}}
% }
% \begin{document}
% ...
% \end{document}
%\end{example}
%The preset value for |logohook| is |tl|.
%\end{description}
%
%A special feature of \pf{powerdot}, which can be used to make
%presentations come alive, is the use of random dots. These dots will
%be placed anywhere on your slides and use the colors defined by the
%palette that you use. Overlays will carry the same dots. This
%feature uses |random.tex| \cite{random}. Several options are
%available to control the appearance of the random dots.
%\begin{description}
%\item\DescribeOption{randomdots}\option{randomdots}\\
%By default, random dots are turned off. If this option is set to
%|true|, random dots will be generated. |false| will turn off the
%feature. When no value is submitted to the option, |true| will be
%used.
%\item\DescribeOptions{dmindots,dmaxdots}\option{dmindots,dmaxdots}\\
%The number of dots per slide is also random. These options set the
%minimum and maximum dots per slide. Preset values are |5| and |40|,
%respectively.
%\item\DescribeOptions{dminsize,dmaxsize}\option{dminsize,dmaxsize}\\
%The minimum and maximum radius of the dots. Preset values are |5pt|
%and |40pt|, respectively.
%\item\DescribeOptions{dminwidth,dmaxwidth,dminheight,dmaxheight}
%\option{dminwidth,dmaxwidth,dminheight,dmaxheight}\\
%These options determine the area on the slide that can be used for
%the random dots. These values are preset such that dots go anywhere
%on the slide, but you might want to adjust these such that, for
%instance, dots can only appear in the text area. The preset values
%are |0pt|, |\slidewidth|, |0pt|, |\slideheight|.
%
%Here is an example that allows dots in a smaller rectangle on the
%slide.
%\begin{example}
% \pdsetup{
%   dminwidth=.1\slidewidth,dmaxwidth=.9\slidewidth,
%   dminheight=.2\slideheight,dmaxheight=.8\slideheight
% }
%\end{example}
%\item\DescribeOption{dbright}\option{dbright}\\
%This option can be used to adjust the brightness of the dots. The
%number should be an integer between -100 and 100. If the number is
%negative, the color will be adjusted towards black, with -100 giving
%black. If the number is positive, the color will be adjusted towards
%white, with 100 giving white. With a light background, you may want
%to choose |bright| to be positive. With a dark background, you may
%want to set it negative. The preset value is |60|, meaning a mixture
%of 40\% of the original color and 60\% white.
%\item\DescribeOption{dprop}\option{dprop}\\
%This option is used for passing extra parameters to the |\psdot|
%command, which creates the random dots. You could, for instance,
%change the style of the dots or the line width. See for more
%information about |\psdot| the \pf{pstricks} documentation
%\cite{PSTricksWeb,PSTricks}. \pf{powerdot} defines two extra dot
%styles that can be used for the random dots. These styles are
%|ocircle| (open circle) and |osquare| (open square).
%\end{description}
%
%Here are two examples for the use of random dots.
%\begin{example}
% \pdsetup{
%   randomdots,dminwidth=.2\slidewidth
% }
%\end{example}
%This turns on random dots and doesn't use the left 20\% of the slide
%for placing random dots.
%\begin{example}
% \pdsetup{
%   randomdots,dprop={dotstyle=ocircle,linewidth=.5pt},
%   dminsize=500pt,dmaxsize=600pt,dmindots=2,dmaxdots=5
% }
%\end{example}
%This example puts at most 5 big circles on slides. These circles do
%not fit on the slides and you will only see parts of them in the
%shape of curves.
%
%\subsubsection{\cs{pdsetup} example}
%Here is an example of a |\pdsetup| command that one could use to set up
%the presentation.
%\begin{example}
% \pdsetup{
%   lf=My first presentation,
%   rf=For some conference,
%   trans=Wipe,
%   theslide=\arabic{slide},
%   randomdots,dmaxdots=80
% }
%\end{example}
%This sets the left and right footers and will initialize the
%transition effect to |Wipe|. Further, slide numbers will not include
%the number of the last slide, but only the number of the current
%slide. Finally, slides will be covered with at most 80 random dots.
%
%A small note is necessary with respect to the appearance of footers.
%The slide number (controlled by the |theslide| option) will be added
%to a footer. Most styles add it too the right footer. If both the
%footer and the slide number are non empty, |~--~| will be inserted
%in between them to separate them. Styles might modify this default
%behavior however.
%
%\section{Making slides}\label{sec:slides}
%\subsection{The title slide}\label{sec:titleslide}
%\DescribeMacro{\title}
%\DescribeMacro{\author}
%\DescribeMacro{\and}
%\DescribeMacro{\date}
%\DescribeMacro{\maketitle}
%The title slide is created by the |\maketitle| command.
%\begin{command}
% `\cs{maketitle}\oarg{options}'
%\end{command}
%Its use is the same as in the standard \LaTeX\ document classes. The
%optional argument \meta{options} can contain any option from
%section~\ref{sec:glopts}. Specifying such an option in the
%|\maketitle| command will only have an effect on the title slide and
%not on other slides. See an example below.
%\begin{example}
% \documentclass{powerdot}
%   \title{Title}
%   \author{You \and me}
%   \date{August 21, 2005}
% \begin{document}
%    \maketitle
%    ...
% \end{document}
%\end{example}
%The |author|, |title| and |date| declarations provide the text to be
%used when making a title page. The design of the title page is
%specific to the style in use. Notice the use of |\and| for
%separating multiple authors. See a \LaTeX\ manual \cite{companion}
%for more information on commands such as |\title| and |\author|.
%
%\subsection{Other slides}\label{sec:otherslides}
%\DescribeEnv{slide} The centerpiece of every presentation is the
%slide. In \pf{powerdot}, the content of each slide is placed in a
%|slide| environment.
%\begin{command}
% `\cs{begin}\texttt{\{slide\}}\oarg{options}\marg{slide title}'
% `\meta{body}'
% `\cs{end}\texttt{\{slide\}}'
%\end{command}
%
%In section~\ref{sec:overlays} we'll see how to give some life to the
%slides, but for now, let's look at a simple example.
%\begin{example}
% \begin{slide}{First slide}
%   Hello World.
% \end{slide}
%\end{example}
%The slide environment has one required argument, namely the slide
%title. When a slide is created, the slide title is used to create an
%entry in the table of contents and in the list of bookmarks. The
%table of contents is a listing of the slides and section titles in
%the presentation that appears on each slide.
%
%The table of contents is clickable (when the presentation is
%compiled into PDF) and serves as a nice way to jump from location to
%location within the presentation. The bookmark list is only present
%when compilation is taken all the way to the PDF file format. It
%also serves as a table of contents, but this list does not appear on
%\textit{any} of the slides, but in a separate window in a PDF
%viewer. In the example above, the entries in both table contents and
%the list of bookmarks would be titled |First slide|.
%
%The \meta{options} for the |slide| environment can contain any
%option listed in section~\ref{sec:glopts}. Additionally, the
%following options can be used.
%\begin{description}
%\item\DescribeOption{toc}\option{toc}\\
%When specified, the value is used for the entry in the table of
%contents; otherwise, the slide title is used. If |toc=| is
%specified, then no entry is created.
%\item\DescribeOption{bm}\option{bm}\\
%When specified, the value is used for the bookmark entry; otherwise,
%the slide title is used. If |bm=| is specified, then no entry is
%created.
%\end{description}
%
%These optional arguments are especially useful when the title of a
%slide is extremely long or when the title contains \LaTeX\ commands
%that do not render correctly in the bookmarks.\footnote{The
%bookmarking procedure uses \cs{pdfstringdef} from the \pf{hyperref}
%package, and it can process accented characters such as \cs{"i}.}
%When specifying entries, be sure to hide special characters `|,|'
%and `|=|' between curly brackets `|{|' and `|}|'. Let's look at an
%example that uses these optional arguments.
%\begin{example}
% \begin{slide}[toc=,bm={LaTeX, i*i=-1}]{\color{red}\LaTeX, $i^2=-1$}
%   My slide contents.
% \end{slide}
%\end{example}
%
%In this example, the slide title will appear as {\color{red}\LaTeX,
%$i^2=-1$}. This text will not render correctly in a bookmark entry.
%An attempt is made to correct this, but often, the correction does
%not produce an equivalent text. This particular title would be
%rendered in the bookmark list as |redLaTeX, i2=-1|. On the other
%hand, the manually specified bookmark entry is rendered as:
%|LaTeX, i*i=-1|. Notice, no entry is created in the table of contents,
%because of the use of |toc=|.
%
%In addition to the |slide| environment, each individual style can
%define its own environments. Many styles have a |wideslide|
%environment. The idea is that one might have information that does
%not fit nicely on a slide with a table of contents listed, as this
%consumes some space. In such cases, it is preferable to use a slide
%that does not list the table of contents. The |wideslide|
%environment provides this functionality and has more space for the
%actual slide content. See section~\ref{sec:styles} for information
%on the various environments provided by the styles.
%
%\section{Overlays}\label{sec:overlays}
%It is often the case that you don't want all the information on the
%slide to appear at once. Rather, the information should appear one
%item at a time. In \pf{powerdot}, this is achieved with overlays.
%Each slide can be comprised of many overlays, and the overlays are
%displayed one at a time.
%
%\subsection{The \cs{pause} command}\label{sec:pause}
%\DescribeMacro{\pause} The easiest way to display information
%sequentially is to use the |\pause| command.
%\begin{command}
% `\cs{pause}\oarg{number}'
%\end{command}
%Below is a simple example:
%\begin{example}
% \begin{slide}{Simple overlay}
%   power\pause dot
% \end{slide}
%\end{example}
%The slide's information is displayed and continues until the
%|\pause| command is encountered. No further output within the same
%slide is displayed until the click of the mouse or the touch of the
%keyboard. Then, the content will continue to display until all the
%information is displayed or until another |\pause| command is
%encountered. In this example, |power| is displayed on the first
%overlay, and |powerdot| is the displayed on the second overlay.  The
%|\pause| command is often used within the |itemize| and |enumerate|
%environments. For example,
%\begin{example}
% \begin{slide}{Multiple pauses}
%   power\pause dot \pause
%   \begin{itemize}
%     \item Let me pause\ldots \pause
%     \item \ldots while I talk \pause and chew bubble gum. \pause
%     \item Perhaps you'll be persuaded.
%     \item Perhaps not.
%   \end{itemize}
% \end{slide}
%\end{example}
%Since |\pause| was used before the |itemize| environment, no item
%will appear until the third overlay. Then, each item will be
%displayed one at a time, each on their own overlay. More information
%on using lists will follow in the next section.
%
%The optional argument of the |\pause| command specifies the number
%of overlays to pause. An example usage is:
%\begin{example}
% \begin{slide}{Pause longer}
%   \begin{itemize}
%     \item A \pause
%     \item B \pause[2]
%     \item C
%   \end{itemize}
% \end{slide}
%\end{example}
%In the example above, item |C| will appear on the fourth overlay.
%The usefulness of this option will become more apparent in the next
%section; so we will revisit a similar example at that time.
%
%\subsection{List environments}\label{sec:lists}
%The list environments, |itemize| and |enumerate|, have special
%treatments in \pf{powerdot}. They have an optional argument that
%will be taken care off by the \pf{enumitem} package (see
%\cite{enumitem}). \pf{powerdot} supplies an extra key for this
%optional argument. In the examples that follow, features will be
%described using the |itemize| environment but they also apply to the
%|enumerate| environment.
%
%Here is the typical usage of the |itemize| environment:
%\begin{example}
% \begin{slide}{Basic itemize}
%   \begin{itemize}
%     \item A \pause
%     \item B \pause
%     \item C
%   \end{itemize}
% \end{slide}
%\end{example}
%The display is simple, each item appears one at a time with each
%overlay.
%
%\DescribeOption{type}
%Suppose we wanted every item to show, but we only wanted one item to
%appear `active' at once. This can be accomplished via the |type|
%option for the |itemize| environment. The preset value is |0|.
%\begin{example}
% \begin{slide}{Type 1 itemize}
%   \begin{itemize}[type=1]
%     \item A \pause
%     \item B \pause
%     \item C
%   \end{itemize}
% \end{slide}
%\end{example}
%Now, every item will be displayed in the \emph{inactive
%color}\index{inactive color|usage} (which is defined by the style
%that you use), and the item's font color will become the active one
%on the overlay that it would normally appear on. The default
%behavior is given by |type=0|. It is still possible
%to pass optional arguments to \pf{enumitem} via the second optional argument:
%\begin{example}
% \begin{slide}{Type 1 itemize}
%   \begin{enumerate}[type=1][label=\roman*a)]
%     \item A \pause
%     \item B \pause
%     \item C
%   \end{enumerate}
% \end{slide}
%\end{example}
%Take care, that this must always be the second optional argument! It is
%possible to leave the first one empty, which is valid only for \pf{powerdot}.
%
%Lists can also be nested to create complicated structures. When a
%list is nested, it inherits the setting of the |type| option from
%the `parent' list, but that can be overruled by specifying the
%|type| option in the optional argument of the nested list. We
%present here one example, but many more can be created by nesting
%lists of different types in different ways.
%\begin{example}
% \begin{slide}{Nested lists}
%   \begin{itemize}
%     \item A\pause
%     \begin{itemize}[type=1]
%       \item B\pause
%     \end{itemize}
%     \item C
%   \end{itemize}
% \end{slide}
%\end{example}
%This displays |A| and |B| on the first overlay, but |B| is inactive.
%On overlay 2, |B| will become active and on overlay 3, |C| will
%become visible.
%
%\subsection{The \cs{item} command}
%\DescribeMacro{\item}
%The |\item| command has an extra \emph{optional} argument in
%\pf{powerdot} which allows for creating overlays in a more flexible
%way then |\pause| provides.
%\begin{command}
% `\cs{item}\oarg{label}\larg{overlays}'
%\end{command}
%This optional argument should contain an overlay specification
%stating on which overlays you want the item to appear. This
%specification is a comma separated list where each item can used the
%notation as in table \ref{tab:item}.
%\begin{table}[htb]\centering
%\begin{tabular}{d}
%Syntax&Meaning\\\hline
%\texttt{x}&Only overlay \texttt{x}\\
%\texttt{-x}&All overlays up to and including \texttt{x}\\
%\texttt{x-}&All overlays from \texttt{x}, including \texttt{x}\\
%\texttt{x-y}&All overlays from \texttt{x} to \texttt{y},
%including \texttt{x} and \texttt{y}\\
%\end{tabular}
%\caption{\cs{item} and \cs{onslide} notation}\label{tab:item}
%\end{table}
%The \meta{label} argument is the standard optional argument for
%|\item| in \LaTeX. A \LaTeX\ manual \cite{companion} can tell you
%more about this argument.
%
%Here is an example.
%\begin{example}
% \begin{slide}{Active itemize}
%   \begin{itemize}[type=1]
%    \item<1> A
%    \item<2> B
%    \item<3> C
%   \end{itemize}
% \end{slide}
%\end{example}
%Here we have said that |A| should only be active on overlay 1, |B|
%should only be active on overlay 2, and |C| should only be active on
%overlay 3. Again, when the item is not active, it appears in the
%inactive color because of |type=1|.
%
%If |type=0| is specified and if each item is given an overlay
%option, then each item will appear only when it is active. When the
%item is not active, then it will not show on the slide at all. More
%examples demonstrating the syntax for \meta{overlays} will be
%discussed in the next section.
%
%\subsection{The \cs{onslide} command}\label{sec:onslide}
%\DescribeMacro{\onslide} Overlays can also be achieved using the
%|\onslide| command.
%\begin{command}
% `\cs{onslide}\marg{overlays}\marg{text}'
%\end{command}
%This command takes an \meta{overlays} specification as first
%argument and the \meta{text} to apply it to as second argument. The
%\meta{overlays} on which the text will appear are specified as a
%comma separated list with syntax as in table \ref{tab:item}. We
%start off with a simple example.
%\begin{example}
% \begin{slide}{Simple onslide}
%   \onslide{1,2}{power}\onslide{2}{dot}
% \end{slide}
%\end{example}
%We have instructed |power| to appear on overlays one and two, and
%|dot| to appear only on overlay two. As you might guess, this
%example has the same output as our first |\pause| example. Yet, it
%is clearly the case that our syntax is more complicated. However,
%this slight ``complication'' also allows for much more flexibility.
%
%\DescribeMacro{\onslide+}Consider the above example with the
%following modifications:
%\begin{example}
% \begin{slide}{Simple onslide+}
%  \texttt{onslide }: \onslide{1}{power}\onslide{2}{dot}\\
%  \texttt{onslide+}: \onslide+{1}{power}\onslide+{2}{dot}
% \end{slide}
%\end{example}
%The |\onslide+| command displays its content in a different manner
%altogether. Now, |dot| appears on every overlay, but it is in
%inactive color\index{inactive color|usage} and matches the normal
%font color \textit{only} on overlay two. This is comparable to the
%|type=1| behavior for lists (see section~\ref{sec:lists}).
%
%When executing this example, we will also notice that the |\onslide|
%command does hide material, but still reserves the right amount of
%space for it: on overlay 2, the |dot|s appear right above each
%other. The next command does not reserve space.
%
%\DescribeMacro{\onslide*} Instead of hiding and reserving space
%(|\onslide|) or putting \meta{text} in the inactive color
%(|\onslide+|) when the overlay doesn't match \meta{overlays}, this
%command just eats the material altogether. To understand the
%differences, consider the following example:
%\begin{example}
% \begin{slide}{Simple onslide*}
%  \texttt{onslide }: \onslide{1}{power}\onslide{2}{dot}\\
%  \texttt{onslide+}: \onslide+{1}{power}\onslide+{2}{dot}\\
%  \texttt{onslide*}: \onslide*{1}{power}\onslide*{2}{dot}
% \end{slide}
%\end{example}
%The output of the first two lines, we are already familiar with. The
%third line displays |power| on overlay 1 and |dot| on overlay 2, but
%no space for |power| is reserved on overlay 2. Hence |dot| will
%start on the cursor position that |power| started on overlay 1 and
%it is not aligned below the other two |dots|.
%
%We finish with an example of the syntax that is possible with
%|\item| and |\onslide|. Remember that these commands take a comma
%separated list for the \meta{overlays} specification and that each
%element can used the syntax as explained in table \ref{tab:item}.
%The various variations are demonstrated in the example below.
%\begin{example}
% \begin{slide}{Lists}
%   \onslide{10}{on overlay 10 only}\par
%   \onslide{-5}{on every overlay before and including overlay 5}\par
%   \onslide{5-}{on every overlay after  and including overlay 5}\par
%   \onslide{2-5}{on overlays 2 through 5, inclusive}\par
%   \onslide{-3,5-7,9-}{on every overlay except overlays 4 and 8}
% \end{slide}
%\end{example}
%
%\subsection{Relative overlays}
%Sometimes it is a pain to keep track of when an item should appear
%or become active. You might, for example, just care that some text
%appears on the overlay \textit{after} some other item. This
%functionality is provided through the use of relative overlays which
%should not be used outside list environments that use |\item|. Let's
%consider a simple, illuminating example.
%\begin{example}
% \begin{slide}{Relative overlays}
%   \begin{itemize}
%     \item A \pause
%     \item B \onslide{+1}{(visible 1 overlay after B)}\pause
%     \item C \onslide{+2-}{(appears 2 overlays after C, visible until the end)}
%     \pause
%     \item D \onslide{+1-6}{(appears 1 overlay after D, visible until overlay 6)}
%     \pause
%     \item E \pause
%     \item F \pause
%     \item G \onslide{+1-+3}{(appears 1 overlay after G for 3 overlays)}\pause
%     \item H \pause
%     \item I \pause
%     \item J \pause
%     \item K
%   \End{itemize}
% \end{slide}
%\end{example}
%As you can see, we still use |\onslide|. The only change is with the
%syntax of the list of overlays. Now, we can specify a `|+|' symbol
%in the list. In its simplest usage, |\onslide{+1}| will make text
%display one overlay after the overlay it would \textit{normally}
%appear on. You can still use the syntax in table \ref{tab:item}.
%These are demonstrated in the above example. Notice,
%|\onslide{+1-6}| means that the text will appear one overlay after

%\section{Presentation structure}\label{sec:structure}
%\subsection{Making sections}\label{sec:section}
%\DescribeMacro{\section}
%This section describes the |\section| command which provides a way
%to structure a presentation.
%\begin{command}
% `\cs{section}\oarg{options}\marg{section title}'
%\end{command}
%This command will produce a slide with \meta{section title} on it
%and will also use this text to create sections in the table of
%contents and in the bookmarks list. There are several \meta{options}
%to control its output.
%
%\DescribeOption{tocsection} This option controls the creation of a
%section in the table of contents. The preset value is |true|.
%\begin{description}
%\item\option{tocsection=true}\\
%This does create a section in the table of contents. This means that
%all following slides, until the next section, will be nested under
%this section.
%\item\option{tocsection=false}\\
%This does not create a section in the table of contents and hence
%the section will be listed as an ordinary slide.
%\item\option{tocsection=hidden}\\
%This does create a section in the table of contents, but this is
%only visible when you view a slide that is part of this section.
%This could be used to append a section to the presentation which you
%can discuss if there is some extra time.
%\end{description}
%
%\DescribeOption{slide} This option controls whether the |\section|
%command creates a slide. The preset value is |true|.
%\begin{description}
%\item\option{slide=true}\\
%A slide is created.
%\item\option{slide=false}\\
%No slide will be created. If also |tocsection| is |false|, the
%|\section| command doesn't do anything. If it does create a table of
%contents section (|tocsection=| |true| or |hidden|), its link will
%point to the first slide in the section as the section itself
%doesn't have a slide.
%\end{description}
%
%\DescribeOption{template} This option can be used to make the
%section slide with another template. By default, a normal |slide|
%environment is used to create the section slide, but if a style
%offers other templates that could be used for this purpose (for
%instance, the |wideslide| environment), then you can use this option
%to select that template. See section~\ref{sec:styles} for an
%overview of the available templates with every style.
%
%Finally, all options available to normal slides are available to
%slides created by |\section| as well (see section~\ref{sec:slides}).
%However, when the section does make a |tocsection|, |toc=| or |bm=|
%won't remove the table of contents entry or the bookmark
%respectively.
%
%\subsection{Making an overview}\label{sec:tableofcontents}
%\DescribeMacro{\tableofcontents}
%This command creates an overview of your presentation and can only
%be used on a slide.
%\begin{command}
% `\cs{tableofcontents}\oarg{options}'
%\end{command}
%There are several \meta{options} to control the output of this
%command.
%
%\DescribeOption{type}
%This option controls whether certain material (depending on the
%input in the |content| option below) will be hidden or displayed in
%the inactive color\index{inactive color|usage}. The preset value is
%|0|. Compare with the |type| option for list environments
%(section~\ref{sec:lists}).
%
%\begin{description}
%\item\option{type=0}\\
%When material is not of the requested type as specified in the
%|content| option, it will be hidden.
%\item\option{type=1}\\
%As |type=0|, but instead of hiding material, it will be typeset in
%the inactive color.
%\end{description}
%
%\DescribeOption{content}
%The |content| option controls which elements will be included in the
%overview. The preset value is |all|. The description below assumes
%that |type=0| was chosen, but the alternative text for |type=1| can
%easily be deduced.
%
%\begin{description}
%\item\option{content=all}\\
%This will display a full overview of your presentation including all
%sections and slides, except the slides in hidden sections (see
%section~\ref{sec:section}).
%\item\option{content=sections}\\
%This displays only the sections in the presentation.
%\item\option{content=currentsection}\\
%This displays the current section only.
%\item\option{content=future}\\
%This displays all content starting from the current slide.
%\item\option{content=futuresections}\\
%This displays all sections, starting from the current section.
%\end{description}
%
%We finish this section with a small example that will demonstrate
%how you can make a presentation that contains an overall overview of
%sections in the presentation, giving a general idea of the content,
%and per section a detailed overview of the slides in that section.
%\begin{example}
% \begin{slide}[toc=,bm=]{Overview}
%   \tableofcontents[content=sections]
% \end{slide}
% \section{First section}
% \begin{slide}[toc=,bm=]{Overview of the first section}
%   \tableofcontents[content=currentsection,type=1]
% \end{slide}
% \begin{slide}{Some slide}
% \end{slide}
% \section{Second section}
% ...
%\end{example}
%
%\section{Miscellaneous}
%\subsection{Notes}\label{sec:notes}
%\DescribeEnv{note}
%The |note| environment can be used to make personal notes that
%accompany a slide. You can control displaying notes using the
%|display| option (see section~\ref{sec:classopts}). Here is an
%example.
%\begin{example}
% \begin{slide}{Chewing gum}
% ...
% \end{slide}
% \begin{note}{Reminder for chewing gum}
%   Don't forget to mention that chewing gum is sticky.
% \end{note}
%\end{example}
%
%\subsection{Empty slides}\label{sec:emptyslides}
%\DescribeEnv{emptyslide}
%The |emptyslide| environment creates a totally empty slide. The text
%box on the slide can be used for special things like displaying
%photos. This allows for creating a dia show. Example:
%\begin{example}
% \begin{emptyslide}{}
%   \centering
%   \vspace{\stretch{1}}
%   \includegraphics[height=0.8\slideheight]{me_chewing_gum.eps}
%   \vspace{\stretch{1}}
% \end{emptyslide}
%\end{example}
%The |\includegraphics| command is defined by the \pf{graphicx}
%package \cite{graphics}. The |\stretch| command is used to
%vertically center the picture. Both commands are described in your
%favorite \LaTeX\ manual, for instance \cite{companion}. Note that
%you can use the lengths |\slideheight| and |\slidewidth| to scale
%pictures to fit nicely on the slide.
%
%\subsection{Bibliography slide}\label{sec:bib}
%\DescribeEnv{thebibliography}
%\pf{powerdot} redefines the standard \pf{article}
%|thebibliography| environment to suppress the creation of a section
%heading and running headers. All other properties are maintained.
%You can do either of the next two (depending whether you are
%using BiB\TeX\ or not):\\
%\begin{minipage}[t]{.49\linewidth}
%\begin{example}
% \begin{slide}{Slide}
%   \cite{someone}
%  \end{slide}
% \begin{slide}{References}
%   \begin{thebibliography}{1}
%   \bibitem{someone} Article of someone.
%   \end{thebibliography}
% \end{slide}
%\end{example}
%\end{minipage}\hfill
%\begin{minipage}[t]{.49\linewidth}
%\begin{example}
% \begin{slide}{Slide}
%   \cite{someone}
% \end{slide}
% \begin{slide}{References}
%   \bibliographystyle{plain}
%   \bibliography{YourBib}
% \end{slide}
%\end{example}
%\end{minipage}
%
%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{natbib}. Using both packages allows you to do:
%\begin{example}
% \begin{slide}{References (1)}
%   \bibliographystyle{plain}
%   \nobibliography{YourBib}
%   \bibentry{someone1}
%   \bibentry{someone2}
% \end{slide}
% \begin{slide}{References (2)}
%   \bibentry{someone3}
% \end{slide}
%\end{example}
%Have a look at your favorite \LaTeX\ manual for more information
%about citations and bibliographies.
%
%\subsection{Verbatim on slides}\label{sec:verbatim}\DescribeOption{verbatim}
%\pf{powerdot} has three different methods of processing slides, from
%which two have mainly been developed to make the inclusion of
%verbatim content\footnote{And other content that needs catcode
%changes when processing.} on slides easier. These methods can be
%accessed by the |method| key which is available in slide
%environments and the |\pdsetup| command (see
%section~\ref{sec:glopts}).
%\begin{description}
%\item\option{method=normal}\\
%This is the preset method for processing slides. It is fast and
%allows for overlays, but it does not allow for
%verbatim.\footnote{Except when it has been saved in a box outside
%the slide.}
%\item\option{method=direct}\\
%This method is also fast, but does not allow for overlays. Overlays
%will silently be disabled. However, it does allow for verbatim
%content on slides.
%\item\option{method=file}\\
%This method uses a temporary file to export the slide body to and
%read it back in. This method does allow for verbatim content and
%overlays, but could be slow when many slides use this method because
%the filesystem is used.
%\end{description}
%
%Below is an example demonstrating the use of all three different
%methods of slide processing.
%\begin{example}
% \documentclass{powerdot}
% \usepackage{listings}
% \lstnewenvironment{code}{%
%   \lstset{frame=single,escapeinside=`',
%   backgroundcolor=\color{yellow!20},
%   basicstyle=\footnotesize\ttfamily}
% }{}
% \begin{document}
% \begin{slide}{Slide 1}
% Normal \pause content.
% \end{slide}
% \begin{slide}[method=direct]{Slide 2}
% Steps 1 and 2:
% \begin{code}
% compute a;`\pause'
% compute b;
% \end{code}
% \end{slide}
% \begin{slide}[method=file]{Slide 3}
% Steps 1 and 2:
% \begin{code}
% compute a;`\pause'
% compute b;
% \end{code}
% \end{slide}
% \end{document}
%\end{example}
%The first slide shows the default behavior for normal content. It
%produces two overlays. The second slide does not produce overlays,
%despite the use of the |\pause| command. This command has been
%disabled by choosing the |direct| method to process the verbatim
%content. The third slide has the same body as the second slide, but
%now does create two overlays, because the method using a temporary
%file has been chosen. Notice that we used |\pause| inside the listing,
%but that it can also be used outside the listing.
%
%\subsection{The \cs{twocolumn} command}\label{sec:twocolumn}
%\DescribeMacro{\twocolumn}
%The |\twocolumn| macro allows to split content into two columns.
%\begin{command}
% `\cs{twocolumn}\oarg{options}\marg{left}\marg{right}'
%\end{command}
%This typesets \meta{left} and \meta{right} in two columns. The
%dimensions of those columns can be controlled by \meta{options}.
%Below are the available options.
%\begin{description}
%\item\DescribeOption{lineheight}\option{lineheight}\\
%If |lineheight| is specified, a line of the specified height will be
%created using |\psline| in between the two columns. Example:
%|lineheight=6cm|.
%\item\DescribeOption{lineprop}\option{lineprop}\\
%Any \pf{pstricks} declaration to specify the line properties. Example:
%\begin{example}
% lineprop={linestyle=dotted,linewidth=3pt}
%\end{example}
%\item\DescribeOptions{lfrheight,lfrprop}\option{lfrheight,lfrprop}\\
%The first creates a frame of the specified height around the left
%column. The second is as |lineprop|, but for the left frame.
%\item\DescribeOptions{rfrheight,rfrprop}\option{rfrheight,rfrprop}\\
%As |lfrheight| and |lfrprop|, but for the right frame.
%\item\DescribeOptions{lcolwidth,rcolwidth}\option{lcolwidth,rcolwidth}\\
%Width of the left and right columns. Both are preset to: |0.47\linewidth|.
%\item\DescribeOption{frsep}\option{frsep}\\
%Space between text and the frames. Preset: |1.5mm|.
%\item\DescribeOption{colsep}\option{colsep}\\
%Space between the two columns. Preset: |0.06\linewidth|.
%\item\DescribeOption{topsep}\option{topsep}\\
%The extra space (additional to |\baselineskip|) between text above
%the columns and the text within the columns. Preset: |0cm|.
%\item\DescribeOption{bottomsep}\option{bottomsep}\\
%Idem for the bottom of the columns. Preset: |0cm|.
%\item\DescribeOption{indent}\option{indent}\\
%Horizontal indent left to the left column. Preset: |0cm|.

%\caption{Two-column dimensions.}\label{fig:twocolumndim}
%\end{figure}
%Important to notice is that the |\twocolumn| 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:twocolumndim}). 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 preset 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
%|\twocolumn| 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 |\twocolumn| 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 specified) 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|). Here is
%an example.
%\begin{example}
% \begin{slide}{Two columns}
%   Here are two columns.
%   \twocolumn[
%     lfrprop={linestyle=dotted,linewidth=3pt},
%     lfrheight=4cm,rfrheight=5cm,lineheight=3cm,topsep=0.3cm
%   ]{left}{right}
%   Those were two columns.
% \end{slide}
%\end{example}
%Note that the use of the \pf{xkeyval} commands |\savevalue| and
%|\usevalue| \index{savevalue=\verb!*+\savevalue+|usage}
%\index{usevalue=\verb!*+\usevalue+|usage} could be handy here, for
%instance for copying the properties of the left frame to the right
%frame. This avoids typing them twice and avoids making errors
%resulting in different frames. See an example below.
%\begin{example}
% \twocolumn[
%   \savevalue{lfrheight}=3cm,
%   \savevalue{lfrprop}={
%     linestyle=dotted,framearc=.2,linewidth=3pt},
%   rfrheight=\usevalue{lfrheight},
%   rfrprop=\usevalue{lfrprop}
% ]{left}{right}
%\end{example}
%See the \pf{xkeyval} documentation \cite{xkeyval} for more
%information about |\savevalue| and |\usevalue|.
%
%\section{Available styles}\label{sec:styles}
%\pf{powerdot} comes with a number of styles which are listed in the
%overview below. The characteristics of each style are described
%shortly and a sample of a title slide and a normal slide is provided
%for each style. Styles support the |wideslide| environment, have a
%table of contents on the left part of the paper in landscape
%orientation and on the bottom part in portrait orientation and
%support portrait orientation unless states otherwise.
%\begin{description}
%\item\pf{default}\\
%This style provides six different palettes. A flower in the top left
%corner decorates the slides for all palettes. The default palette is
%\texttt{blue} which has as main colors light blue and white. You can
%see an example of that palette below. Other available palettes are
%\texttt{red}, \texttt{green}, \texttt{yellow}, \texttt{brown} and
%\texttt{purple}.\\
%\styleexample{default}
%\item\pf{simple}\\
%This is a simple style in black and white. This style could be
%useful if you want to print your slides.\\
%\styleexample{simple}
%\item\pf{tycja}\\
%This style is set in shades of yellow and dark blue. The table of
%contents on slides is on the right side of the paper in landscape
%orientation and on the bottom part in portrait.\\
%\styleexample{tycja}
%\item\pf{ikeda}\\
%This style uses dark shades of red and blue and a light text color.
%It has nice patterns on the slide for decoration.\\
%\styleexample{ikeda}
%\item\pf{fyma}\\
%This style was originally created by Laurent Jacques for
%\pf{prosper}. Based on that style, he created a version for
%\pf{HA-prosper} with extended features. With his kind permission,
%this style has been converted by Shun'ichi J. Amano for
%\pf{powerdot}. The style has an elegant design with a light blue and
%white gradient background in the default \texttt{blue} palette.
%Other available palettes are \texttt{green}, \texttt{gray},
%\texttt{brown} and \texttt{orange}. It has special templates for
%sections on slides and sections on wide slides. Below is a sample of
%the blue palette.\\
%\styleexample{fyma}
%\item\pf{ciment}\\
%This style was originally created by Mathieu Goutelle for
%\pf{prosper} and \pf{HA-prosper}. With his kind permission, this style
%has been converted for \pf{powerdot}. The style has a background
%that is hatched with light gray horizontal lines. Titles and table
%of contents highlighting are done with dark red.\\
%\styleexample{ciment}
%\item\pf{elcolors}\\
%This is a style using light shades of the elementary colors red,
%blue and yellow.\\
%\styleexample{elcolors}
%\item\pf{aggie}\\
%This style was created by Jack Stalnaker for \pf{HA-prosper} and he
%has converted this style for \pf{powerdot}. The style uses dark red
%and light brown colors.\\
%\styleexample{aggie}
%\item\pf{husky}\\
%This style is created by Jack Stalnaker and has a background of
%light gray sun beams combined with dark red highlights.\\
%\styleexample{husky}
%\item\pf{sailor}\\
%This style is contributed by Mael Hill\'ereau and supplies five
%different palettes: \texttt{Sea} (the default), \texttt{River},
%\texttt{Wine}, \texttt{Chocolate} and \texttt{Cocktail}. Below is a
%sample of the palette \texttt{Sea}.\\
%\styleexample{sailor}
%\item\pf{upen}\\
%This style has a nice dark blue background and text in yellow. It is
%contributed by Piskala Upendran.\\
%\styleexample{upen}
%\item\pf{bframe}\\
%The \pf{bframe} style has blue frames on the slide in which text is
%positioned. The style is contributed by Piskala Upendran.\\
%\styleexample{bframe}
%\item\pf{horatio}\\
%The \pf{horatio} style has been contributed by Michael Lundholm and
%is a more conservative blue style.\\
%\styleexample{horatio}
%\item\pf{paintings}\\
%This is a simple style without a table of contents on slides. It has
%been contributed by Thomas Koepsell and provides 10 different
%palettes. The colors used in the palettes are drawn from famous
%paintings.\footnote{The style defines a color \texttt{pdcolor7}
%which is not used in the style but comes from the same painting and
%complements the other colors. It can be used, for example, to
%highlight text against the main background color.} If you are
%interested, open the style file to read which paintings have been
%used. The available palettes are: \texttt{Syndics} (the default),
%\texttt{Skater}, \texttt{GoldenGate}, \texttt{Lamentation},
%\texttt{HolyWood}, \texttt{Europa}, \texttt{Moitessier},
%\texttt{MayThird}, \texttt{PearlEarring} and \texttt{Charon} (all
%case sensitive). Below is a sample of the \texttt{Syndics}
%palette.\\
%\styleexample{paintings}
%\item\pf{klope}\\
%The \pf{klope} style implements a horizontal table of contents that
%only lists the sections. The style is available in the following
%palettes: \texttt{Spring}, \texttt{PastelFlower}, \texttt{BlueWater}
%and \texttt{BlackWhite}. The \texttt{Spring} palette is the default
%and you can see a sample of that below.\\
%\styleexample{klope}
%\item\pf{jefka}\\
%The \pf{jefka} style comes with four palettes: \texttt{brown} (the
%default), \texttt{seagreen}, \texttt{blue} and \texttt{white}. Below
%you see a sample of the \texttt{brown} palette.\\
%\styleexample{jefka}
%\item\pf{pazik}\\
%This style is available in two palettes: \texttt{red} and
%\texttt{brown}. Below is a sample of the default \texttt{red}
%palette.\\

%\section{Compiling your presentation}\label{sec:compiling}
%\subsection{Dependencies}\label{sec:dependencies}
%In table \ref{tab:dependencies} is a list of packages that
%\pf{powerdot} uses to perform specific tasks. Dependencies of
%packages in this table are not listed. In the table, `required'
%means that you should have a version \emph{at least} as new as
%listed and `tested' means that \pf{powerdot} was tested with this
%version, but that it could equally well work with an older or newer
%version than the one listed in the table. So, when trying to solve
%an error, first concentrate on solving version issues for the
%`required' packages. To find out which version of a package you are
%currently using, put |\listfiles| on the first line of your
%document, run it with \LaTeX, open the |.log| file and read the file
%list (see a \LaTeX\ manual for more information). If you need to
%update a package, you can get it from CTAN \cite{CTAN}.

%the presentation incorrectly. If your DVI viewer does support
%this, make sure that your DVI display settings match that of the
%presentation. In case you are using the |screen| paper, you should
%set the DVI display setting to using the letter paper format. If
%your DVI viewer allows for custom paper formats, use 8.25 inch by 11
%inch.
%
%Note that certain things that are produced with PostScript or PDF
%techniques will not work in a DVI viewer. Examples are hiding of
%material via postscript layers (as is done, for instance, by
%|\pause|, see section~\ref{sec:overlays}) and hyperlinks, for
%instance in the table of contents.
%
%If you want to produce a postscript document, run dvips over the DVI
%\emph{without any particular command line options related to
%orientation or paper size}. \pf{powerdot} will write information to
%the DVI file that helps dvips and ps2pdf (ghostscript) to create a
%proper document. If you have some reason that this does not work for
%you and you want to specify the paper and orientation yourself, you
%should use the |nopsheader| option that is described in
%section~\ref{sec:setup}. The PostScript document could, for
%instance, be used to put multiple slides on a page using the |psnup|
%utility.
%
%To create a PDF document for your presentation, run ps2pdf over the
%PS file created with dvips. Also here, you can \emph{leave out any
%command line arguments related to paper size or orientation}. If
%this is problematic for you somehow, use the |nopsheader| option as
%before and specify the paper and orientation at each intermediate
%step yourself.
%
%\section{Creating your own style}\label{sec:writestyle}
%\subsection{General information}
%Writing or customizing \pf{powerdot} styles is simple. If you want
%to modify a style or build a new one, locate the style that you want
%to use as basis in your \TeX\ tree (styles are named as
%|powerdot-<style_name>.sty|), copy that and rename it as to avoid
%license\footnote{The \LaTeX\ Public Project License requires
%renaming files when modifying them, see
%\url{http://www.latex-project.org/lppl}.} or naming conflicts. You
%might want to install the new style in your local \TeX\ tree to be
%able to access it from any place on your hard drive. See your
%\LaTeX\ distribution for more information.
%
%Once that has been taken care of, we can start creating the style.
%We strongly recommend to study a style file (for example,
%|powerdot-default.sty|) while reading the remainder of this section
%as it provides good examples for the content of this section.
%
%A style has several components. We describe these components below.
%\begin{description}
%\item\textbf{Identification and packages}\\
%This identifies the package in the log of a presentation and loads
%all required packages. The \pf{default} style contains something like:
%\begin{example}
% \NeedsTeXFormat{LaTeX2e}[1995/12/01]
% \ProvidesPackage{powerdot-default}[2005/10/09 v1.2 default style (HA)]
% \RequirePackage{pifont}
%\end{example}
%See for more information about these commands a \LaTeX\ manual, for
%instance \cite{companion}.
%\item\textbf{Palette or color definitions}\\
%This section contains the definitions of palettes or colors that you
%want to use in the style. \pf{powerdot} uses \pf{xcolor} (via
%\pf{pstricks}). Hence, for more information about colors, see the
%\pf{xcolor} documentation. We will discuss palettes in more detail
%in section~\ref{sec:defpals}.
%\item\textbf{Template definitions}\\
%We will come back to this in sections~\ref{sec:deftemps}
%to~\ref{sec:defbg}.
%\item\textbf{Custom declarations}\\
%These can include anything that you want to be part of the style.
%The \pf{default} style, for instance, includes definitions for the labels
%in list environments like |itemize| and some initializations for
%lists in general (done with |\pdsetup|, see
%section~\ref{sec:pdsetup}). This part could also include some
%customizations as described in section~\ref{sec:specialtemps}.
%\item\textbf{Font initializations}\\
%This initializes font definitions (which can be done by
%loading a package like \pf{helvet}).
%\end{description}
%
%\subsection{Defining palettes}\label{sec:defpals}
%We will be defining templates formally in
%section~\ref{sec:deftemps}. For now, it's enough to have the general
%idea that a template controls the design of a slide. Palettes are
%sets of colors that color a template or design. A palette does not
%change the overall design of a template.
%
%\DescribeMacro{\pddefinepalettes}
%The following command can be used to define palettes for your style.
%\begin{command}
% `\cs{pddefinepalettes}\marg{name1}\marg{cmds1}\dots'
%\end{command}
%This macro takes \emph{any} even number of mandatory arguments with
%a minimum of two. For every \meta{name}, a set of \meta{commands}
%can be given which define the palette with name \meta{name}. These
%commands can define colors with names |pdcolor1|, |pdcolor2|,
%etcetera. These colors can be used when designing the template (see
%section~\ref{sec:deftemps}). |pdcolor1| will always be used as text
%color.
%
%The user can access these palettes via the |palette| key for the
%|\pdsetup| command (see section~\ref{sec:pdsetup}). If the user does
%not specify a palette, the first palette defined when compiling the
%presentation, will be used. Here is an example for defining 2
%palettes.
%\begin{example}
% \pddefinepalettes{reds}{
%   \definecolor{pdcolor1}{rgb}{1,0,0}
%   \definecolor{pdcolor2}{rgb}{1,.1,0}
%   \definecolor{pdcolor3}{rgb}{1,.2,0}
% }{greens}{
%   \definecolor{pdcolor1}{rgb}{0,1,0}
%   \definecolor{pdcolor2}{rgb}{.1,1,0}
%   \definecolor{pdcolor3}{rgb}{.2,1,0}
% }
%\end{example}
%In this example, the |reds| palette is the default one. For more
%information about |\definecolor|, see the documentation of the
%\pf{xcolor} package \cite{xcolor}.
%
%Notice that it is not necessary to use the names |pdcolor2|,
%|pdcolor3| etcetera as color names. But if these colors are defined,
%\pf{powerdot} will use them, for instance, in the random dots
%feature (see section~\ref{sec:glopts}). The flexibility adds extra
%possibilities in setting up templates and palettes. See for an
%example of its use, the \pf{klope} style.
%
%\subsection{Defining templates}\label{sec:deftemps}
%We start off with a definition of what a template is. A template is
%a collection of settings for slide components together with custom
%definitions, which controls the visual appearance of a slide. A
%style can contain multiple templates.
%
%\begin{command}
% `\cs{pddefinetemplate}\oarg{basis}\marg{name}\marg{options}\marg{commands}'
%\end{command}
%\DescribeMacro{\pddefinetemplate}
%This defines the environment \meta{name} to produce a slide with
%characteristics determined by \meta{basis}, \meta{options} and
%\meta{commands}. We will discuss these elements in more detail
%in the coming sections.
%
%If you want to create several templates that differ only slightly
%from each other, define a \meta{basis} template, and then use it to
%define other templates. All \meta{options} and \meta{commands} for
%the new template \meta{name} will be appended to the existing list
%of \meta{options} and \meta{commands} from the \meta{basis}
%template.
%
%Make sure you choose a \emph{proper} name for the template, and
%avoid redefining existing templates or environments. \pf{powerdot}
%defines |pauseslide|, |note| and |emptyslide| internally, so you
%shouldn't use these names unless you know what you're doing.
%Furthermore, each style needs to define at least the templates
%|slide| and |titleslide|. The |titleslide| environment will be used
%to create the title slide and |slide| will (by default) also be used
%to create section slides. Titles and sections are a bit special in
%the way they use the \meta{options} and will be discussed in more
%detail in section~\ref{sec:specialtemps}.
%
%\subsection{Controlling setup}
%\DescribeOption{ifsetup}
%The \meta{options} (keys) are described in the following sections.
%You can control how these options apply to the various setups by
%using the |ifsetup| key. Any key appearing before the first
%|ifsetup| declaration in \meta{options} will apply to every possible
%setup. Once the |ifsetup| key is used, then all subsequent key
%declarations will apply \textit{only} to the setups declared in the
%|ifsetup| key. The |ifsetup| key can be used multiple times.
%
%By possible setups, we mean the allowed values of the |mode|,
%|paper|, |orient|, and |display| keys that are described in
%section~\ref{sec:classopts}. If a value (or values!) for any of
%these four keys is not specified in a |ifsetup| declaration, then
%all subsequent key declarations will apply to any layout of that
%type. Consider the following as an example.
%\begin{example}[numbers=left,numberstyle=\tiny\ttfamily,%
%  escapeinside=`',numbersep=1em,xleftmargin=1em]
% ...
% textpos={.2\slidewidth,.3\slideheight},%
% ifsetup={portrait,screen},%
% textpos={.3\slidewidth,.2\slideheight}%
% ...
% ifsetup=landscape,%
% ...
% ifsetup,
% ...
%\end{example}
%Assuming there was no |ifsetup| declaration before the first
%|textpos| declaration, this first |textpos| will apply to every
%possible setup. However, for the screen format in portrait
%orientation, the next |textpos| declaration will be used. In fact,
%all declarations that appear until we switch to the next |ifsetup|
%(which specifies all paper sorts and only landscape orientation)
%will be used in the portrait screen layout. All keys after the next
%|ifsetup| declaration will be used in landscape orientation,
%\emph{with any paper, mode and display}. If, after declaring some
%specializations, you want to switch back to settings that apply to
%all possible setups, set |ifsetup| to empty as is done in the
%example. All subsequent declarations will then again be applied
%under any setup.
%
%The following command is a stand-alone implementation of the
%mechanism described above. It allows you to control the setup
%outside the \meta{options} argument of the |\pddefinetemplate|
%command.
%\begin{command}
% `\cs{pdifsetup}\marg{desired}\marg{true}\marg{false}'
%\end{command}
%\DescribeMacro{\pdifsetup}
%This macro executes \meta{true} when the setup that the user chose
%matches with the \meta{desired} setup, \meta{false} in all other cases.
%For instance, if the user has chosen landscape, then
%\begin{example}
% \pdifsetup{landscape}{yes}{no}
%\end{example}
%will typeset |yes|. If the user would have chosen portrait instead,
%then |no| would have been typeset.
%
%This macro can be used to check setup requests from the user and,
%for instance, generate an error if a certain setup is not supported
%by your style. \pf{powerdot} provides one predefined error message
%which can be used in one of the first lines of your style.
%\begin{command}
% `\cs{pd@noportrait}'
%\end{command}
%\DescribeMacro{\pd@noportrait}
%This macro generates an error when the user requests portrait
%orientation. Notice that the handout mode only works in portrait
%orientation. This macro takes that into account and doesn't generate
%an error in the case that the user requested a handout.
%
%\subsection{Main components}\label{sec:maincomps}
%The \meta{options} control several key components of a slide. Every
%component has several properties. A key that can be used in the
%\meta{options} argument is the name of the component postfixed by
%its property that you want to control.
%
%The components |title|, |text|, |toc|, |stoc| and |ntoc| have
%properties |hook|, |pos|, |width| and |font|. Additionally, the
%|text| component has a |height| property. The components |lf|, |cf| and
%|rf| have properties |hook|, |pos|, |temp| and |font|. Hence,
%examples of valid keys are |titlefont|, |tocpos| and |lftemp|. All
%components and properties will be discussed below.
%
%Here is an overview of the components that can be controlled from
%the \meta{options} argument in |\pddefinetemplate|.
%\begin{description}
%\item\DescribeOption{title-}\option{title-}\\
%The slide title.
%\item\DescribeOption{text-}\option{text-}\\
%The main text box on the slide.
%\item\DescribeOption{toc-}\option{toc-}\\
%The (full) table of contents on a slide containing sections and
%slides.
%\item\DescribeOption{stoc-}\option{stoc-}\\
%This is a table of contents containing only the sections. See also
%|ntoc| below.
%\item\DescribeOption{ntoc-}\option{ntoc-}\\
%This is a table of contents containing only the entries for the
%active section. Together with |stoc|, this can be used to create a
%split table of contents. In a particular template, one would usually
%have a |toc|, a combination of |stoc| and |ntoc| or no table of
%contents at all.
%\item\DescribeOptions{lf-,cf-,rf-}\option{lf-,cf-,rf-}\\
%The left, center and right footers.
%\end{description}
%
%Notice that all positioning of components described above will be
%done with |\rput| from \pf{pstricks} \cite{PSTricksWeb,PSTricks}
%internally. See the \pf{pstricks} documentation for more information
%about this command. It should also be noted that all components
%(except |lf|, |cf| and |rf|) put their content in a |minipage|
%environment.
%
%Now we list all properties of the components listed above and
%describe what they mean. Remember that keys are formed by combining
%a component name and a property.
%
%\begin{description}
%\item\DescribeOption{-hook}\option{-hook}\\
%This option defines the |\rput| hook that will be used when
%positioning the item. This can be |tl|, |t|, |tr|, |r|, |Br|, |br|,
%|b|, |bl|, |Bl|, |l|, |B| and |c|. See the \pf{pstricks}
%documentation for more information.
%\item\DescribeOption{-pos}\option{-pos}\\
%This defines the position of the |hook| on the paper. The lower left
%corner of the paper is given by the point |{0,0}| and the upper right
%corner by the point |{\slidewidth,\slideheight}|. So if you want to
%position the main text box at 20\% from the left edge and 30\% from
%the top edge of the paper, you have to do the following.
%\begin{example}
% textpos={.2\slidewidth,.7\slideheight}
%\end{example}
%If the position of any component has not been specified, this
%component will not be placed on the slide. This gives an opportunity
%to design slides without footers or table of contents, for instance.
%\item\DescribeOption{-width}\option{-width}\\
%The width of the component. All component positioned by
%\pf{powerdot} will be put in a surrounding |minipage| environment.
%The |width| property determines the width of the |minipage|. Example:
%\begin{example}
% textwidth=.7\slidewidth
%\end{example}
%This property does not exist for the |lf|, |cf| and |rf| components.
%\item\DescribeOption{-height}\option{-height}\\
%This option is only available for the |text| component. In other
%words, for this property, there is only one key, namely
%|textheight|. This can be used to specify the height of the
%|minipage| used for the main text. This does not imply that users
%are restricted to this length or that \pf{powerdot} does automatic
%slide breaking. This height is only used for vertical alignments of
%material, for instance by footnotes. The preset value is
%|\slideheight|.
%\item\DescribeOption{-font}\option{-font}\\
%This will be inserted just before the text that is about to be
%typeset. This can be used to declare deviations from the main text
%font and color. It can be a font declaration, like
%|\large\bfseries|, but can also contain other things like
%|\color{red}| or |\raggedright|.
%\item\DescribeOption{-temp}\option{-temp}\\
%This property is only available for the footers (|lf|, |cf| and |rf|) and
%can be used to change the template of the footers. This means that
%you can, for instance, add content to the footer, besides the
%content specified by the user. The default declaration by
%\pf{powerdot} is the following.
%\begin{example}
% rftemp=\pd@@rf\ifx\pd@@rf\@empty
%   \else\ifx\theslide\@empty\else\ -- \fi\fi\theslide
%\end{example}
%Here |\pd@@rf| will contain the content of the right footer defined
%by the user via the |\pdsetup| command. Similarly, |\pd@@lf|
%contains the content of the left footer. The above declaration
%checks whether the footer and |\theslide| are both non-empty and if
%so, it inserts | -- | to separate both.
%\item\DescribeOption{-orient}\option{-orient}\\
%This property is only available for the |toc|, |stoc| and |ntoc|
%components. This property can be |h| or |v| and determines the
%orientation of the table of contents. The preset is |v|. See
%also section~\ref{sec:slidetoc} for more information about the
%construction of the table of contents.
%\end{description}
%
%\subsection{Slide toc}\label{sec:slidetoc}
%The small table of contents that is placed on slides can be
%controlled by four macros and several options.
%
%\DescribeMacro{\pd@tocslide}
%\DescribeMacro{\pd@tocsection}
%These macros take one argument. When building the table of contents,
%\pf{powerdot} first passes the content through |\pd@tocslide| or
%|\pd@tocsection|, depending on the type of entry that it is building
%at that moment. You could, for instance, do
%\begin{example}
% \def\pd@tocslide#1{$\bullet$\ #1}
% \def\pd@tocsection#1{#1}
%\end{example}
%which will prefix all normal entries (not the sections) with a
%bullet. By default, these two macros are defined to just pass on
%their argument.
%
%\DescribeMacro{\pd@tocdisplay}
%\DescribeMacro{\pd@tochighlight}
%These two macros also take one argument. After processing an entry
%with the command |\pd@tocslide| or |\pd@tocsection|, \pf{powerdot}
%continues building the entry by passing it through |\pd@tocdisplay|,
%when the entry needs to be displayed only, or |\pd@tochighlight|,
%when the entry needs to be highlighted. These macros are a little
%more involved and take care of putting the content in the proper
%font and color in a |minipage|. Further, |\pd@tochighlight| also
%puts a box around the item.
%
%Notice, that by default, both the separate table of contents entries
%as well as the table of contents as a whole are typeset in
%|minipage| environments by these macros, in case the table of
%contents is vertical. The |-width| properties then determines the
%width of the table of contents and, together with |tocsecindent| and
%|tocslideindent| (see below) the width of the individual entries. If
%it is horizontal, only the separate entries will be in |minipage|s
%and the table of contents itself not and the |-width| properties
%determine only the width of the individual entries (together with
%|tocsecindent| and |tocslideindent|).
%
%Several aspects of the process of generating the table of contents
%can be controlled via the keys that are available in the
%|\pddefinetemplate| command that will be described below. If these
%keys do not provide enough handles to do what you want, you might
%need to have a look at the two macros in the source and decide to
%rewrite them in your style as to fit your needs. An example can be
%found in the \pf{fyma} style.
%
%\begin{description}
%\item\DescribeOption{tocfrsep}\option{tocfrsep}\\
%This length is the distance between the box around the content
%created by the |minipage| and the highlight frame box created by
%|\pd@tochighlight|. Preset: |0.5mm|.
%\item\DescribeOption{tocsecsep}\option{tocsecsep}\\
%The distance inserted before a section (unless it is the
%first element in the table of contents). Preset: |2ex|.
%Notice that if the orientation of the table of contents is set to
%vertical, this length creates a vertical skip, otherwise, it creates
%a horizontal skip.
%\item\DescribeOption{tocslidesep}\option{tocslidesep}\\
%The distance inserted before other entries (unless it is the
%first element in the table of contents). Preset: |0ex|. Like
%|tocsecsep|, the effect of this length depends on the orientation of
%the table of contents.
%\item\DescribeOption{tocsecindent}\option{tocsecindent}\\
%The horizontal space left to a section entry. Preset: |0pt|.
%\item\DescribeOption{tocslideindent}\option{tocslideindent}\\
%The horizontal space left to a slide entry. The horizontal skip will
%not be inserted left to slide entries that appear before the first
%section. Preset: |0pt|.
%\item\DescribeOption{tocsecm}\option{tocsecm}\\
%This is inserted just before typesetting a section. This can be used
%to mark a section, for instance with a line as in the \pf{default}
%style. Preset: empty.
%\item\DescribeOption{toctcolor}\option{toctcolor}\\
%This is the text color used for non-highlighted elements in the
%table of contents. Preset: |black|.
%\item\DescribeOption{tochltcolor}\option{tochltcolor}\\
%This is the text color used for highlighted elements in the table of
%contents. Preset: |white|.
%\item\DescribeOption{tochlcolor}\option{tochlcolor}\\
%This is the color used for the frame behind highlighted elements.
%Preset: |black|.
%\end{description}
%
%\subsection{Miscellaneous options}\label{sec:miscoptions}
%There are some options that fall outside of the scope of the previous
%sections. These will be discussed here.
%
%\begin{description}
%\item\DescribeOption{iacolor}\option{iacolor}\\
%The |iacolor| option can be used to specify the color that is used
%for inactive things, produced for instance by |\onslide|, |\pause|
%(see section~\ref{sec:overlays}) and |\tableofcontents| (see
%section~\ref{sec:tableofcontents}). As \pf{xcolor} is used by
%\pf{powerdot}, one can use special notation here, like
%\begin{example}
% iacolor=black!20
%\end{example}
%The preset value for this key is |lightgray|.
%\end{description}
%
%The following options control the digital clock (see
%section~\ref{sec:classopts}). The clock is a form text field with
%dynamic content, driven by a javascript via \pf{hyperref} text
%fields. Some options for the clock work similarly as for, for
%instance, the title component, but there are also special options.
%\begin{description}
%\item\DescribeOptions{clockhook,clockpos}\option{clockhook,clockpos}\\
%These work in the same way as the |-hook| and |-pos| properties
%discussed in section~\ref{sec:maincomps}. The preset value of
%|clockhook| is |tr|.
%\item\DescribeOptions{clockwidth,clockheight}\option{clockwidth,clockheight}\\
%These control the width and height of the text field containing the
%clock. Preset values come from \pf{hyperref} and are |3cm| and
%|\baselineskip|, respectively.
%\item\DescribeOption{clockcharsize}\option{clockcharsize}\\
%The size of characters of the clock. Preset: |14pt|.
%\item\DescribeOption{clockalign}\option{clockalign}\\
%The alignment of the clock in the text field. |0| is left-aligned,
%|1| is centered and |2| is right aligned. Preset is |2|.
%\item\DescribeOption{clockcolor}\option{clockcolor}\\
%This determines the text color of the clock. The value should be a
%named color. The preset value is |black|.
%\end{description}
%
%\subsection{Template presets}
%Below, we have copied the preset setting for the keys described
%above. These will be used if you didn't supply other input for these
%keys in a particular template. If the preset value meets your
%needs, you don't have to specify it again in your style.
%\begin{example}
% titlehook=Bl,titlepos=,titlewidth=\slidewidth,
% titlefont=\raggedright,texthook=tl,textpos=,
% textwidth=\slidewidth,textfont=\raggedright,
% textheight=\slideheight,
% tochook=tl,tocpos=,tocwidth=.2\slidewidth,
% tocfont=\tiny\raggedright,
% stochook=tl,stocpos=,stocwidth=.2\slidewidth,
% stocfont=\tiny\raggedright,
% ntochook=tl,ntocpos=,ntocwidth=.2\slidewidth,
% ntocfont=\tiny\raggedright,
% tocorient=v,stocorient=v,ntocorient=v,
% tocfrsep=.5mm,tocsecsep=2ex,tocslidesep=0ex,
% tocsecm=,toctcolor=black,tochlcolor=black,tochltcolor=white,
% tocsecindent=0pt,tocslideindent=0pt,
% lfhook=Bl,lfpos=,lffont=\scriptsize,lftemp=\pd@@lf,
% cfhook=B,cfpos=,cffont=\scriptsize,cftemp=\pd@@cf,
% rfhook=Br,rfpos=,rffont=\scriptsize,rftemp=\pd@@rf\ifx\pd@@rf
%   \@empty\else\ifx\theslide\@empty\else\ -- \fi\fi\theslide,
% iacolor=lightgray,
% clockhook=tr,clockpos=,clockwidth=3cm,clockheight=\baselineskip,
% clockcharsize=14pt,clockalign=2,clockcolor=black
%\end{example}
%
%\subsection{The background}\label{sec:defbg}
%This leaves only one argument of the |\pddefinetemplate| macro
%undiscussed. This is the \meta{commands} argument. This argument can
%contain any code that you want to execute \textit{after} setting the
%options and \textit{before} building the slide components like the
%slide title, main text, and footers. This argument is designed to
%contain declarations that will build the background of a template
%using, for instance, \pf{pstricks}, but it can also hold other
%commands you might need for building your template.
%
%Important to notice is that these commands may not create \TeX\
%material as that might destroy the construction of the slide. So, if
%you want to place the word `Hello' in the bottom left corner of the
%slide, don't type `Hello', but make its width, height and depth
%equal to zero, for instance by using \pf{pstricks}' |\rput|.
%\begin{example}
% \rput[bl](0,0){Hello}
%\end{example}
%
%\subsection{Title slide, titles and sections}\label{sec:specialtemps}
%As mentioned before, the style that you write needs to define at
%least the templates |slide| and |titleslide|. The latter treats some
%of the keys in a special way. Besides, a section slide is also done
%in a special way.
%
%The title slide (made with |\maketitle|) puts the title with
%author(s) and date in the main text box. This means that you have to
%supply a position for the main text box (|textpos|). It will use the
%main text font for the text (together with declarations in the
%|textfont| key) for the author(s) and the date. But it will use the
%declarations in |titlefont| for the title of the presentation. This
%is done so that title and author(s) form a coherent block and to
%make sure that long titles can push down the author(s) instead of
%overwriting it.
%
%\DescribeMacro{\pd@slidetitle}
%The |\pd@slidetitle| macro is used to typeset the slide title on
%slides. This macro is comparable to for instance |\pd@tocslide|. The
%macro takes one argument which is the slide title in the right font
%and formatting. By default, this macro just passes on the content
%for typesetting, but you could redefine this macro so do something
%with its input prior to typesetting it. An example is in the
%\pf{fyma} style which underlines the title after putting it in a
%|minipage| to support multi line titles.
%
%\DescribeMacros{\pd@title,\pd@sectiontitle}
%These macros are similar to |\pd@slidetitle| and typeset the title
%on the title slide and the title on section slides respectively. By
%default, these also pass there argument (which is the presentation
%title or section title), but these can be redefined to do something
%with the input prior to typesetting it, just as |\pd@slidetitle|.
%
%\DescribeOptions{sectemp,widesectemp}
%The |\section| command uses (by default) the |slide| environment and
%puts the section title in the title box with font |titlefont|. If
%you want to change the default use of the |slide| environment for
%sections to, for instance, the |sectionslide| environment or any
%other especially designed section template, change the section
%template preset in your style, using
%\begin{example}
% \setkeys[pd]{section}{sectemp=sectionslide}
%\end{example}
%This means that if the user asks for |template=slide| in the
%|\section| command, the |sectionslide| environment will be used
%silently. To avoid surprises, |sectionslide| should preferably be
%based on the |slide| environment.
%
%A similar option is available in case the user asks for
%|template=wideslide|. One could for instance do the following.
%\begin{example}
% \setkeys[pd]{section}{widesectemp=sectionwideslide}
%\end{example}
%Whenever the user requests a |wideslide| to be used for a
%|\section|, instead, the |sectionwideslide| environment will be
%used. Other input to the |template| key by the user does not get a
%special treatment.
%
%Notice that these keys are available in the |section| family of keys
%and that you cannot use them in the |\pddefinetemplate| command.
%
%\subsection{Testing the style}\label{sec:styletest}
%\pf{powerdot} has a test file that should test most of the style.
%This test file can be produced by running \LaTeX\ over
%|powerdot.dtx|. This generates |powerdot-styletest.tex| which will
%help you with the testing job. Feel free to contact us when you
%would like to contribute your style to \pf{powerdot}. See also
%section~\ref{sec:questions}.
%
%\section{Using \LyX\ for presentations}\label{sec:lyx}
%\LyX\ \cite{LyXWeb} is a WYSIWYM (What You See Is What You Mean)
%document processor based on \LaTeX. It supports standard \LaTeX\
%classes but needs special files, called layout files, in order to
%support non-standard classes such as \pf{powerdot}.
%
%To start using \LyX\ for \pf{powerdot} presentations, copy the
%layout file |powerdot.layout| to the \LyX\ layout directory. You can
%find this file in the doc tree of your \LaTeX\ installation:
%\url{texmf/doc/latex/powerdot}. If you can't find it there, download
%it from \url{CTAN:/macros/latex/contrib/powerdot}. Once that is
%done, reconfigure \LyX\ (\texttt{Edit\LyXarrow Reconfigure} and
%restart \LyX\ afterwards). Now you can use the \pf{powerdot}
%document class as any other supported class. Go to
%\texttt{Layout\LyXarrow Document} and select \texttt{powerdot
%presentation} as document class. For more information, see the \LyX\
%documentation, which is accessible from the |Help| menu.
%
%\subsection{How to use the layout}
%The \pf{powerdot} \LyX\ layout provides some environments\footnote{Don't
%confuse these with \LaTeX\ environments.} which can be used in \LyX.
%Some of these environments (for instance |Title| or |Itemize|) are
%natural to use since they exist also in the standard document
%classes such as \pf{article}. For more information on these standard
%environments, see the \LyX\ documentation.
%
%This section will explain how to use the \pf{powerdot} specific
%environments |Slide|, |WideSlide|, |EmptySlide| and |Note|. These
%environments correspond to the \pf{powerdot} environments |slide|,
%|emptyslide|, |wideslide| and |note|.
%
%We start with a simple example. The following \LaTeX\ code
%\begin{example}
% \begin{slide}{Slide title}
%   Slide content.
% \end{slide}
%\end{example}
%can be obtained using the following \LyX\ environments. The right
%column represents the text typed into the \LyX\ window and the left
%column represents the environment applied to this text).
%\begin{example}
% Slide         Slide title
% Standard      Slide content.
% EndSlide
%\end{example}
%Some remarks concerning this example.
%\begin{itemize}[leftmargin=0pt,itemsep=0pt,parsep=0pt]
%\item You can use the environment menu (under the menu bar, top-left
%corner) to change the environment applied to text.
%\item The slide title should be typed on the line of the |Slide|
%environment.
%\item |EndSlide| finishes the slide and its line is left blank.
%\end{itemize}
%
%In the \LyX\ window, the |Slide| environment (that is, the slide
%title) is displayed in magenta, the |WideSlide| style in green, the
%|EmptySlide| style in cyan and the |Note| style in red and hence
%these are easily identifiable.
%
%Here is another example.
%\begin{example}
% \begin{slide}{First slide title}
%   The first slide.
% \end{slide}
% \begin{note}{First note title}
%   The first note, concerning slide 1.
% \end{note}
% \begin{slide}{Second slide title}
%   The second slide.
% \end{slide}
%\end{example}
%This can be done in \LyX\ in the following way.
%\begin{example}
% Slide         First slide title
% Standard      The first slide.
% Note          First note title
% Standard      The first note, concerning slide 1.
% Slide         Second slide title
% Standard      The second slide.
% EndSlide
%\end{example}
%This example demonstrates that it is often sufficient to insert the
%|EndSlide| style after the last slide or note only. Only when you
%want certain material not to be part of a slide, you need to finish
%the preceding slide manually using the |EndSlide| style. Example:
%\begin{example}
% Slide         First slide title
% Standard      The first slide.
% EndSlide
% [ERT box with some material]
% Slide         Second slide title
% ...
%\end{example}
%
%Options can be passed to slide environments by using
%\texttt{Insert\LyXarrow Short title} in front of the slide title.
%The following example uses the |direct| method (see
%section~\ref{sec:verbatim}) in the short title argument (delimited by
%square brackets) to allow for a |lstlisting| environment (defined by
%the \pf{listings} package) within the slide content.
%\begin{example}
% Slide         [method=direct]Example of LaTeX source code
% Standard      Here's the \HelloWorld command:
% [ERT box:
%   \lstset{language=[LaTeX]TeX}
%   \begin{lstlisting}
%   \newcommand{\HelloWorld}{Hello World!}
%   \end{lstlisting}
% ]
% EndSlide
%\end{example}
%Note that you are not obliged to use a |verbatim| environment to
%type the |\HelloWord| text into the \LyX\ window because \LyX\
%directly supports standard verbatim.\footnote{\LyX\ translates
%special characters into their corresponding \LaTeX\ command. For
%instance, the backslash character is translated into
%\cs{textbackslash{}}. Resulting, the font is not the same as in true
%verbatim and you might want to change that via the
%\texttt{Layout\LyXarrow Character} dialog.} Consequently, the use of
%the slide processing methods |direct| and |file| is not necessary
%when you need standard verbatim, but it is necessary when doing more
%advanced things, like in the example above.
%
%\subsection{Support of syntax}
%This section lists options, commands and environments that are
%supported through the \LyX\ interface directly, without using an ERT
%box (\TeX-mode).
%
%All class options (see section~\ref{sec:classopts}) are supported
%via the \texttt{Layout\LyXarrow Document} dialog (|Layout| pane).
%Options for the |\pdsetup| command (see section~\ref{sec:setup})
%should be specified in the |Preamble| pane of the
%\texttt{Layout\LyXarrow Document} dialog.
%
%Table \ref{tab:lyxcommands} lists the \pf{powerdot} commands that
%are supported in \LyX.

%\subsection{Compiling with \LyX}
%First of all, make sure that you have also read
%section~\ref{sec:compiling}. Then, in order to get a proper
%PostScript or PDF file, you have to set your \LyX\ document
%properties depending on which paper and orientation you want. When
%your \LyX\ document is open, go to the \texttt{Layout\LyXarrow
%Document} dialog. In the \texttt{Layout} pane, put the |nopsheader|,
%|orient| and |paper| keys as class options (see
%section~\ref{sec:classopts} for a description). Then, go to the
%|Paper| pane and select corresponding paper size and orientation
%(you may choose |letter| paper in the case you set |paper=screen| in
%the class options). Finally, go to the |View| (or
%\texttt{File\LyXarrow Export}) menu and select your output
%(PostScript or PDF).
%
%\subsection{Extending the layout}
%If you have created a custom style (see section~\ref{sec:writestyle})
%which defines custom templates, you may want to extend the layout
%file\footnote{The LPPL dictates to rename a file if you modify it as
%to avoid confusion.} so that these templates are also supported in
%\LyX. The explanation below assumes that you have defined a template
%called |sunnyslide|.
%
%To support this new template in \LyX, you have to use the following
%command.
%\begin{command}
% `\cs{pddefinelyxtemplate}\meta{cs}\marg{template}'
%\end{command}
%\DescribeMacro{\pddefinelyxtemplate}
%This will define the control sequence \meta{cs} such that it will
%create a slide with template \meta{template} (which has been defined
%using |\pddefinetemplate|. This new control sequence can be used in
%the layout file as follows.
%\begin{example}
% # SunnySlide environment definition
% Style SunnySlide
%   CopyStyle     Slide
%   LatexName     lyxend\lyxsunnyslide
%   Font
%     Color       Yellow
%   EndFont
%   Preamble
%     \pddefinelyxtemplate\lyxsunnyslide{sunnyslide}
%   EndPreamble
% End
%\end{example}
%Note that you must begin the |LatexName| field with |lyxend|. The
%definition of the \LyX\ template has been inserted in between
%|Preamble| and |EndPreamble| which assures that the new \LyX\
%environment will work in every presentation. After modifying the
%layout file, don't forget to restart \LyX. See for more information
%about creating \LyX\ environments, the documentation of \LyX\ in the
%|Help| menu.

%\section{Questions}\label{sec:questions}
%\subsection{Frequently Asked Questions}\label{sec:FAQ}
%This section is devoted to Frequently Asked Questions. Please read
%it carefully; your problem might be solved by this section.
%\begin{itemize}[leftmargin=0pt]
%\question
%Does \pf{powerdot} have example files? Where can I find them?
%\answer
%\pf{powerdot} comes with several examples that should be in the doc
%tree of your \LaTeX\ installation. More precisely:
%\url{texmf/doc/latex/powerdot}. If you can't find them there,
%download them from \url{CTAN:/macros/latex/contrib/powerdot}
%\cite{CTAN}.
%\question I'm getting errors or unexpected output when compiling
%the simplest example!
%\answer Did you read section~\ref{sec:compiling}?
%\question I made a typo in the slide code, ran the file, got an
%error, corrected the typo and reran, but now get an error that
%doesn't go away.
%\answer Remove the |.bm| and |.toc| files and try again.
%\question |\pause| does not work in the |align|\footnote{There are
%several environments doing similar things as \texttt{align}. Another
%example is the \texttt{split} environment, but more (often from the
%\pf{amsmath} package) can cause similar trouble for \cs{pause}.}
%environment.
%\answer |align| does several tricky things, which make it impossible
%to use |\pause|. Use |\onslide| instead. See
%section~\ref{sec:onslide}.
%\question My \pf{pstricks} nodes appear on all overlays. Also: color
%doesn't seem to work with |\onslide|.
%\answer Some PostScript tricks like nodes and color do not work with
%|\onslide|. Use |\onslide*| instead. See an example below.
%\begin{example}
% \documentclass{powerdot}
% \usepackage{pst-node}
% \begin{document}
% \begin{slide}{Color}
% \onslide*{2}{\cnode(0,-5pt){2pt}{A}}
% This is {\onslide*{2-}{\color{red}} red} text.
% \onslide*{2}{\cnode(0,-5pt){2pt}{B}}
% \onslide{2}{\ncline{A}{B}}
% \end{slide}
% \end{document}
%\end{example}
%\question Do I need to edit style files to change a style a bit?
%\answer No, you do not need to edit any style file. You can change
%any part of a certain style using the |\pddefinetemplate| and
%|\pddefinepalettes| commands. Here is an example that removes the
%left and right footers from the \pf{default} style, places the slide
%number in the center footer and adds another palette.
%\begin{example}
% \documentclass{powerdot}
% \pddefinetemplate[slide]{slide}{
%   lfpos=,rfpos=,cftemp=\theslide
% }{}
% \pddefinepalettes{mypalette}{
%   \definecolor{pdcolor1}{rgb}{.27,.31,.44}
%   \definecolor{pdcolor2}{rgb}{.85,.85,.92}
%   \definecolor{pdcolor3}{rgb}{.8,.75,.98}
% }
% \pdsetup{palette=mypalette}
% \begin{document}
% \begin{slide}{Title}
% \end{slide}
% \end{document}
%\end{example}
%See section~\ref{sec:writestyle} for more information about these
%two commands.
%\question Can I contribute to this project?
%\answer
%Certainly. If you find bugs\footnote{Make sure that you confirm that
%the bug is really caused by \pf{powerdot} and not by another package
%that you use.} or typos, please send a message to the mailinglist
%(see section~\ref{sec:mailinglist}). If you have developed your own
%style that is distinct from existing styles and would like to see it

%\section{Implementation}\label{sec:imple}
%\subsection{General construction}
%This section explains the general idea of the class, how paper
%dimensions are chosen and how slides are created. We start with the
%paper.
%
%This class uses the same idea as \pf{prosper} and \pf{HA-prosper},
%namely that we create a background with \pf{pstricks} and position
%text on it using |\rput| and some |minipage| environments. This is
%easier than writing a dedicated output routine that can handle all
%the material, but doesn't break pages when we don't want that. So,
%when starting to write the class, we first investigated how to deal
%with landscape slides and paper dimensions.
%
%The job of making landscape slides can be done using \pf{geometry}.
%The paper dimension was more of a problem. As \LaTeX\ doesn't have
%the huge fonts that we need for presentations, we need to scale the
%usual fonts somehow. This could be done by using unusual paper
%dimensions (as \pf{beamer} does) and hence relying on ps2pdf to cut
%off all the redundant material. But this doesn't produce a usable
%DVI or PS file. Instead, it was chosen to use DVI magnification. The
%entire slide is magnified by a factor of 2 and only the top left
%quarter of the paper is used (but you will never notice that due to
%the magnification). As we already decided to place all material in
%|minipage|s using |\rput|, we didn't need the page anymore and it
%was easiest to use \pf{geometry} to just remove the page margins
%altogether so that the bottom left corner would be |(0,0)| and the
%top right corner |(\slidewidth,\slideheight)|.
%
%One extra remark on the paper type is necessary. We found that most
%common configurations of dvips use the |A4size| code when A4
%dimensions are found. This code doesn't write an explicit PostScript
%paper command in the PS document and hence programs using this PS
%(like ps2pdf) don't know what paper to use and revert to the
%default, which is letter paper in most cases. This, of course, is
%something that we don't want and hence, \pf{powerdot} will write
%these commands to the PS itself as to guarantee proper post
%processing of the PS.
%
%Now that we made the decisions on how to create proper DVI, PS and
%PDF output, the next task was to create an easy interface to
%overlays. To avoid counting the overlays as is necessary with
%\pf{prosper}, we implemented a system that first collects the entire
%body of an environment in a macro which can be reused multiple
%times. During execution of the body, the overlay commands like
%|\onslide| will keep a record of the biggest number that they find
%and that is the number of overlays to produce. Getting the body of
%the environment is done by collecting all material up to the next
%|\end| occurrence. If that control sequence has the proper argument
%(namely the slide that we started with), then we stop scanning and
%start processing the slide. With normal use, you will not notice
%this, but when doing special tricks like hiding |\end{slide}| in a
%macro, the process will fail as it relies on finding |\end{slide}|
%in the input stream without doing expansions. Often a work around
%can be found though. Have a look for instance at how |\section|
%creates a slide.
%
%The next task was to provide a simple way to create templates. As
%the class is based on the idea of having a background with some
%material spread out over it, the template system follows this idea.
%One argument can be used to create the background, the other
%argument controls, via keys and options, several properties of the
%material that should be placed. By adding an |ifsetup| key, full
%control could be gained over the design of the template in every
%possible setup chosen by the user.
%
%The final task for the class was to fill in all the `details'. All
%the mechanisms were present, but sometimes they should not be
%active. For instance, overlays should not be created in handout
%mode. Other things to add to the class were counter protection on
%overlays, handles to the layout of the slide number, footnotes, a
%bibliography environment, empty slides, etcetera.
%
%We hope that this section has made clear a little bit what you will
%be seeing when reading the next section with coding and why we chose
%to do it this way.

% |\next| occurs in the \pf{verbatim} macros. We define it to close

% do this as this content (probably |\lyxslide|) has been sanitized
% while reading in verbatim mode. We could also use |\scantokens|
% if we keep in mind that that, just as |\input|, introduces line
% feeds and end-of-file characters in the input stream which the
% \pf{verbatim} macros can't handle. Morten H\o gholm proposed the

    The two of you may find it amusing to listen
    to such totally meaningless cacophony, but I assure you it is not at
    all pleasant for a sensitive composer to be subjected to such
    excruciating, empty dissonances and meaningless rhythms.  Achilles,
    I thought you had a good feeling for music. Could it be that your
    previous pieces had merit merely by coincidence?
