%
% \section{Introduction}
%
% The \LaTeX\ package \textsf{beamertheme-tuni} provides a no-frills
% \textsf{beamer} theme that follows the
% \href{https://www.tuni.fi/en}{Tampere Universities} (TUNI) graphical
% guidelines. The aim is to provide maximum space for content.
%
% \begin{itemize}
%   \item supports all aspect ratios
%   \item bilingual (finnish, english)
% \end{itemize}
%
% \section{Usage}
%
% \subsection{Installation}
% \label{sec:installation}
%
% Obtain the latest version of the \textsf{beamertheme-tuni} package from
% \begin{quote}
%   \url{https://github.com/tvalimaki/beamertheme-tuni}
% \end{quote}
% The recommended installation method is using the provided |Makefile|
% described in the next section.
%
% \subsubsection{Using the provided \texttt{Makefile}}
%
% To extract the package, build this documentation, and an example
% presentation, run |make all|. To install the files on the |texmf| tree in
% |TEXMFHOME|, run |make install|. To undo, run |make uninstall|.
%
% \subsubsection{Manually}
%
% If for some reason the provided |Makefile| does not work for you, it is
% possible to install the files manually. First, extract the package
% definition by running
% \begin{quote}
%   |etex beamerthemetuni.dtx|
% \end{quote}
% This creates the files |beamerthemetuni.sty| and |beamercolorthemetuni.sty|.
%
% \changes{v1.1}{2019/07/29}{Specify PDF compatibility level 1.5 in install
%   intructions}
%
% Next generate |pdf| versions of the graphics by running
% \begin{quote}
%   |find . -name '*.eps' -exec \| \\
%   |    epstopdf --gsopt=-dCompatibilityLevel=1.5 {} \;|
% \end{quote}
%
% In order for \TeX\ to find the package, it needs to be on the |texmf| tree.
% By default, \TeX\ looks for files in three different locations:
% \begin{itemize}
%   \item The root |texmf| tree, which is usually located at
%     |/usr/share/texmf/|, |/usr/local/texlive/texmf/|, |c:\texmf\|, or
%     |c:\texlive\texmf\|.
%   \item The local |texmf| tree, which is usually located at
%     |/usr/local/share/texmf/|, |/usr/local/texlive/texmf-local/|,
%     |c:\localtexmf\|, or |c:\texlive\texmf-local\|.
%   \item Your personal |texmf| tree, which is usually located in your home
%     directory at |~/texmf/| or |~/Library/texmf/|.
% \end{itemize}
%
% You should install the package in your personal tree, or if you prefer, to
% the local tree. Installation in the root tree can cause problems, since an
% update of the whole \TeX\ installation will replace this entire tree.
%
% Inside whatever |texmf| directory you have chosen, create the
% sub-sub-sub-directory
% \begin{quote}
%   |texmf/tex/latex/beamertheme-tuni|
% \end{quote}
% and place all |.sty| and both |.pdf| and |.eps| versions of the graphics
% in this directory.
%
% Finally, you need to rebuild \TeX{}’s filename database. This is done by
% running the command |texhash| or |mktexlsr|.
%
% To produce this documentation you can run
% \begin{quote}
%   |pdflatex --shell-escape beamerthemetuni.dtx|\\
%   |makeindex -s gglo.ist -o beamerthemetuni.gls beamerthemetuni.glo|\\
%   |makeindex -s gind.ist -o beamerthemetuni.ind beamerthemetuni.idx|\\
%   |pdflatex beamerthemetuni.dtx|\\
%   |pdflatex beamerthemetuni.dtx|
% \end{quote}
% and optionally place the created documentation in
% \begin{quote}
%   |texmf/doc/latex/beamertheme-tuni|
% \end{quote}
% for later reference.
%
% To produce an example presentation run
% \begin{quote}
%   |pdflatex beamerthemetuni-example.tex|\\
%   |biber beamerthemetuni-example|\\
%   |pdflatex beamerthemetuni-example.tex|\\
%   |pdflatex beamerthemetuni-example.tex|
% \end{quote}
%
% For a more detailed explanation of the standard installation process of
% packages, you might wish to consult
% \url{http://www.ctan.org/installationadvice/}.
%
% \subsection{Package options}
%
% \DescribeMacro{finnish} The package option |finnish| loads language support
% for finnish and typesets the titlepage of the presentation with the finnish
% logo. If not provided, the default language for the document and logo is
% english.
%
% \DescribeMacro{sectionpages} The package option |sectionpages| starts each
% section with a table of contents highlighting the current location in the
% presentation. The sectionpage is set on a purple background.
%
% \DescribeMacro{purple} The frame option |purple| sets the slide background
% to purple, foreground to white, and structure to blue. The selection can be
% made per slide using
% \begin{verbatim}
%\begin{frame}[purple]{Frame title}
%    Frame content.
%\end{frame}
% \end{verbatim}
%
% A custom text can be added to the frame footer by setting the
% \textsf{beamer} template |frame footer|.
% \begin{verbatim}
%\setbeamertemplate{frame footer}{My custom footer}
% \end{verbatim}
%
% \subsection{Minimal working example}
%
% The code to produce a presentation consisting of a titlepage and three
% frames.
% \VerbatimInput[frame=single]{mwe.tex}
% results in the presentation
% \vskip\medskipamount

% derived files, see Section~\ref{sec:installation}.

\section{Introduction}
\subsection{Main features}
\begin{frame}[containsverbatim]{Main features}
  \alert{A no-frills Beamer theme} that follows the
  \emph{Tampere Universities} (TUNI) graphical guidelines. The aim is to
  provide maximum space for content.

  \begin{itemize}
    \item supports all aspect ratios
    \item bilingual (finnish, english)
    \begin{itemize}
      \item load the theme using \verb|\usetheme[finnish]{tuni}| to get
        finnish language support and logo
    \end{itemize}
  \end{itemize}
  \bigskip
  Get the source of the newest version from
  \begin{center}\url{https://github.com/tvalimaki/beamertheme-tuni}\end{center}
\end{frame}

\note{%
  This is how a note page looks like if you use the beameroptions
  ``show notes'' or ``show notes on second screen''
}

\begin{frame}[containsverbatim,purple]{Colors}
  \framesubtitle{2/2}
  The theme offers an optional dark slide background\footnote{Nothing like a
  little change to spruce things up.}.
  The selection can be made per slide using:

  \begin{lstlisting}
  \begin{frame}[purple]{Frame title}
      Frame content.
  \end{frame}
  \end{lstlisting}
\end{frame}

\subsection{Font}
\begin{frame}{Typeface}
  The theme uses Open Sans\footnote{A humanist sans-serif typeface designed by
  Steve Matteson and commissioned by Google.} as the default font.
  The available font weights are:

  \begin{description}
    \item[light] {\fontseries{l}\selectfont Lorem ipsum dolor sit amet}
    \item[medium] {\fontseries{m}\selectfont Lorem ipsum dolor sit amet}
    \item[semibold] {\fontseries{sb}\selectfont Lorem ipsum dolor sit amet}
    \item[bold] {\fontseries{b}\selectfont Lorem ipsum dolor sit amet}
    \item[extrabold] {\fontseries{eb}\selectfont Lorem ipsum dolor sit amet}
  \end{description}

  The typewriter/monospaced font is Bera Mono\footnote{A version of Bitstream
  Vera Mono slightly enhanced for use with \TeX{}}.

  \begin{description}
    \item[medium] \texttt{Lorem ipsum dolor sit amet}
    \item[bold] \textbf{\texttt{Lorem ipsum dolor sit amet}}
  \end{description}
\end{frame}

  \begin{theorem}
      There is no largest prime number.
  \end{theorem}
  \begin{proof}
  \begin{enumerate}
    \item<1-| alert@1> Suppose $p$ were the largest prime number.
    \item<2-> Let $q$ be the product of the first $p$ numbers.
    \item<3-> Then $q+1$ is not divisible by any of them.
    \item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime
      number not in the first $p$ numbers.\qedhere
