\section{Structuring a Presentation: The Local Structure}
-\LaTeX\ provides different commands for structuring text ``locally,''
-for example, via the |itemize| environment. These environments
-are also available in the \beamer\ class, although their appearance has
-been slightly changed. Furthermore, the \beamer\ class also defines
-some new commands and environments, see below, that may help you to
-structure your text.

-There are three predefined environments for creating lists, namely
-|enumerate|, |itemize|, and |description|. The first
-two can be nested to depth three, but nesting them to this depth

-The |\item| command is overlay-specification-aware. If an overlay
-specification is provided, the item will only be shown on the
-specified slides, see the following example. If the |\item|

The following \meta{options} can be given:
\begin{itemize}
- \item \declare{|wd=|\marg{width}} sets the width of the box. This
- command has two effects: First, \TeX's |\hsize| is set to
- \meta{width}. Second, after the box has been typeset, its width is
- set to \meta{width} (no matter what it actually turned out to
- be). Since setting the |\hsize| does not automatically change some
- of \LaTeX's linewidth dimensions, you should consider using a
- minipage inside this environment if you fool around with the
- width.
-
- If the width is larger than the normal text width, as specified by
- the value of |\textwidth|, the width of the resulting box is reset
- to the width |\textwidth|, but intelligent negative skips are
- inserted at the left and right end of the box. The net effect of
- this is that you can use a width larger than the text width for a
- box and can insert the resulting box directly into normal text
- without getting annoying warnings and having the box positioned
- sensibly.
- \item \declare{|dp=|\marg{depth}} sets the depth of the box,
- overriding the real depth of the box. The box is first typeset
- normally, then the depth is changed afterwards. This option is
- useful for creating boxes that have guaranteed size.
-
- If the option is not given, the box has its ``natural'' depth,
- which results from the typesetting. For example, a box containing
- only the letter ``a'' will have a different depth from a box
- containing only the letter ``g.''
- \item \declare{|ht=|\meta{height}} sets the height of the box,
- overriding the real height. Note that the ``height'' does not
- include the depth (see, for example, the \TeX-book for
- details). If you want a one-line box that always has the same
- size, setting the height to 2.25ex and the depth to 1ex is usually
- a good option.
- \item \declare{|left|} causes the text inside the box to be typeset
- left-aligned and with a (radically) ragged right border. This is
- the default. To get a better ragged right border, use the
- |rightskip| option.
- \item \declare{|right|} causes the text to be right-aligned with a
- (radically) ragged left border.
- \item \declare{|center|} centers the text inside the box.
- \item \declare{|leftskip=|\meta{left skip}} installs the \meta{left
- skip} inside the box as the left skip. \TeX's left skip is a
- glue that is inserted at the left end of every line. See the
- \TeX-book for details.
- \item \declare{|rightskip=|\meta{right skip}} install the
- \meta{right skip}. To get a good ragged right border, try, say,
- |\rightskip=0pt plus 4em|.
- \item \declare{|sep=|\meta{dimension}} sets the size of extra
- space around the text. This space is added ``inside the box,''
- which means that if you specify a |sep| of 1cm and insert the box
- normally into the vertical list, then the left border of the box
- will be aligned with the left border of the slide text, while the
- left border of the text inside the box will be 1cm to the right of
- this left border. Likewise, the text inside the box will stop 1cm
- before the right border of the normal text.
- \item \declare{|colsep=|\meta{dimension}} sets the extra ``color
- separation space'' around the text. This space behaves the
- same way as the space added by |sep|, only this space is only
- inserted if the box has a colored background, that is, if the
- background of the \meta{beamer color} is not empty. This command
- can be used together with |sep|, the effects accumulate.
- \item \declare{|colsep*=|\meta{dimension}} sets an extra color
- separation space around the text that is \emph{horizontally
- outside the box}. This means that if the box has a background,
- this background will protrude by \meta{dimension} to the left and
- right of the text, but this protruding background will not be
- taken intro consideration by \TeX\ for typesetting purposes.
-
- A typical example usage of this option arises when you insert a
- box with a coloured background in the middle of normal text. In
- this case, if the background color is set, you would like a
- background to be drawn behind the text \emph{and} you would like a
- certain extra space around this text (the background should not
- stop immediately at the borders of the text, this looks silly)
- \emph{and} you would like the normal text always to be at the same
- horizontal position, independently of whether a background is
- present or not. In this case, using |colsep*=4pt| is a good
- option.
- \item \declare{|shadow|}\opt{|=|\meta{true or false}} draws a shadow
- behind the box. Currently, this option only has an effect if
- used together with the |rounded| option, but that may change.
- \item \declare{|rounded|}\opt{|=|\meta{true or false}} causes the
- borders of the box to be rounded off if there is a background
- installed. This command internally calls |beamerboxesrounded|.
- \item \declare{|ignorebg|} causes the background color of the
- \meta{beamer color} to be ignored, that is, to be treated as if it
- were set to ``transparent'' or ``empty.''
- \item \declare{vmode} causes \TeX\ to be in vertical mode when the
- box starts. Normally, \TeX\ will be in horizontal mode at the
- start of the box (a |\leavevmode| is inserted automatically at the
- beginning of the box unless this option is given). Only
- \TeX perts need this option, so, if you use it, you will
- probably know what you are doing anyway.

In certain situation you may instead wish a certain text or graphic to appear at a page position that is specified \emph{absolutely}. This means that the position is specified relative to the upper left corner of the slide.
+The package |textpos| provides several commands for positioning text absolutely and it works together with \beamer. When using this package, you will typically have to specify the options |overlay| and perhaps |absolute|. For details on how to use the package, please see its documentation.
\subsection{Verbatim and Fragile Text}
-If you wish to use a |{verbatim}| environment in a frame, you have to
-add the option |[fragile]| to the |{frame}| environment. In this case,
-you really have to use the |{frame}| environment (not the |\frame|
-command) and the |\end{frame}| must be alone on a single line. Using
-this option will cause the frame contents to be written to an external
-file and the read back. See the description of the |{frame}|
-environment for more details.
-
-You must also use the |[fragile]| option for frames that include any
-``fragile'' text, which is any text that is not ``interpreted the way
-text is usually interpreted by \TeX.'' For example, if you use a
-package that (locally) redefined the meaning of, say, the character
-|&|, you must use this option.
-
-Inside |{verbatim}| environments you obviously cannot use commands
-like |\alert<2>| to highlight part of code since the text is written
-in, well, verbatim. There are several good packages like |alltt| or
-|listings| that allow you to circumvent this problem. For simple
-cases, the following environment can be used, which is defined by
-\beamer:
