+These files are available from \weblink{www.ctan.org}{www.ctan.org}. You might already have (some of) them.
+\vskip3mm
+You need the program {\cf pdftex}, which probably is included in your \TeX-distribution.
+\vskip3mm
+You also need a pdf-viewer with fullscreen display capabilities, e.g. {\cf xpdf}.
+\vskip5pt
+\att{Some pdf-viewers do not handle links in a document properly.}

+\NewSlide
+\SlideTitle{\hfil Basic Examples}
+You can type text as usual, inline equations $a^2+b^2=c^2$, displayed equations
+$$
+\exp(z)=\sum_{n=0}^\infty {z^n\over n!}=\lim_{n\to\infty}\Big(1+{z\over n}\Big)^n

+}}\vskip5pt
+So you probably can use \TeX\ in the ordinary fashion; just run {\cf pdftex} on your source instead of {\cf tex}.
+\NewSlide
+You can include images easily:\vskip20pt plus 3pt minus 10pt

+\NewSlide

+\SlideTitle{\hfil Ordinary stuff}
+You type text, equations, and so on as usual in \TeX. Keep in mind, though, that the effective paper size is 
+rather small (12cm wide, 9cm high in standard configuration).
+\vskip20pt plus 5pt minus 10pt
+The paper size is small, because you rely on the fullscreen mode of your pdf-viewer to blow the slide up to full 
+screen size, thus also automatically enlarging the fonts.
+\vskip20pt plus 5pt minus 10pt
+Your macros should work (unless there is a collision of names), because what you are doing is creating an ordinary
+pdf-file with {\cf pdftex}, for viewing it with a pdf-viewer.
+\NewSlide
+%%%
+%%%
+%%%
+\SlideTitle{\hfil Fonts}
+{\cf present.tex} defines the following fonts:\vskip5pt
+{\openup2pt
+\halign{#\hfil\kern10pt&#\hfil\kern10pt&#\hfil\cr
+Font Command & Purpose & Default Value\cr
+{\cf\char'134 titlefont} & presentation title & {\cf cmssbx10 at 20pt}\cr
+{\cf\char'134 slidetitlefont} & title of a slide & {\cf cmssbx10}\cr
+{\cf\char'134 normalfont} & ordinary text & {\cf cmss12}\cr
+{\cf\char'134 linkbarfont} & text in {\cf\char'134 LinkBar} & {\cf cmss8}\cr
+{\cf\char'134 it} & italic text & {\cf cmti12}\cr
+}}
+\vskip10pt
+Of course you can define further font commands or redefine the existing ones.
+The default fonts are used in this presentation, so you see what they look like.
+\NewSlide
+%%%
+%%%
+%%%
+\SlideTitle{\hfil Colours}
+Colour effects are handled by the {\cf color.sty}-package included via {\cf color.tex}.
+
+The following colours are
+defined in {\cf present.tex}:
+\vskip5pt
+{\cf background}, for the slide background 
+\vskip5pt
+{\cf text}, for the text, and
+\vskip5pt
+{\cf attention}, an \att{attention} colour.
+\vskip5pt
+Colour names can be defined and redefined by
+\vskip5pt
+{\cf\char'134 definecolor\char'173}{\it NAME\/}{\cf\char'175\char'173 rgb\char'175\char'173}{\it R,G,B\/}%
+{\cf\char'175}
+\vskip5pt
+where {\it NAME} is a colour name to be defined, like {\cf background} or {\cf mycolour}, and {\it R}, 
+{\it G}, and {\it B} are
+the red, green, and blue values describing the colour; $0\leq\hbox{ {\it R}, {\it G}, {\it B} }\leq 1$.
+\NewSlide
+%%%
+%%%
+%%%
+Once defined, the colours are employed as follows:
+\vskip3pt
+{\cf\char'134 pagecolor\char'173 background\char'175} sets the colour of the slide background to {\cf background}.
+\vskip3pt
+{\cf\char'134 color\char'173 text\char'175} sets the colour of subsequent text to {\cf text}.
+\vskip3pt
+{\cf\char'134 textcolor\char'173 text\char'175\char'173}{\it Stuff\/}{\cf\char'175} prints {\it Stuff} 
+in colour {\cf text}.
+\vskip5pt
+The colour {\cf attention} is mainly used in the macro {\cf\char'134 att}, which prints 
+\att{Stuff} in attention colour by saying
+{\cf\char'134 att\char'173}{\it Stuff\/}{\cf \char'175}.
+\NewSlide
+%%%
+%%%
+%%%
+\SlideTitle{\hfil Paper Size}
+The paper size is determined by the parameters {\cf\char'134 pdfpagewidth} and
+{\cf\char'134 pdfpageheight}. 
+\vskip10pt
+If you say {\cf\char'134 StandardAspect}, you get a page 120mm wide and 90mm high.
+\vskip10pt
+If you say {\cf\char'134 WideAspect}, you get a page 144mm wide and 90mm high.
+\NewSlide
+%%%
+%%%
+%%%
+\SlideTitle{\hfil Images}
+Images can be included with
+\vskip5pt
+{\cf\char'134 image[}{\it dimensions}{\cf]\char'173}{\it filename}{\cf\char'175}
+\vskip5pt
+where {\it dimensions} are {\cf height}, {\cf depth}, and {\cf width}, familiar from \TeX.
+\vskip5pt
+\hbox{%
+\image[width3mm]{Stern.png}
+\image[width6mm]{Stern.png}
+\image[width9mm]{Stern.png}
+\image[height9mm]{Stern.png}
+\image[height3mm depth6mm]{Stern.png}
+\image[height9mm width4mm]{Stern.png}
+\image[width5mm]{Sagnac.pdf}\image[width10mm height4mm]{Sagnac.pdf}
+\image[width15mm depth 5mm]{Sagnac.pdf}
+}
+\vskip5pt
+If only {\cf width} is given, the image is scaled with the aspect ratio preserved.\target{Images}
+
+Image files need to be in a format that can be handled by the pdf-viewer and by {\cf pdftex}.
+E.g. pdf, png, jpg should work.
+\NewSlide
+%%%
+%%%
+%%%
+\pagecolor{background}
+\SlideTitle{\hfil Slide Structure}
+Each slide has a headline, a body, and a footline.
+\vskip5pt
+The headline holds the slide title, which is set by 
+\vskip5pt
+{\cf\char'134 SlideTitle\char'173}{\it TITLE\/}{\cf\char'175}
+\vskip5pt
+The footline is defined by 
+{\cf\char'134 SlideFoot}, of which several versions are contained in {\cf present.tex}. Uncomment the one you want,
+or define further ones.
+\vskip5pt
+The version used here shows the number of the current slide and the total number of slides in the centre (the latter is
+provided by the {\cf\char'134 LP} macro), and the {\cf\char'134 PageBar} on the right.
+
+The {\cf\char'134 PageBar}-symbols \PageBar move to the previous or following page, or move back and forth in the 
+page history.

+{The page history is relevant if cross-references are used in the presentation. These will be discussed subsequently.}

+\SlideTitle{\hfil Links}
+{\cf\char'134 target\char'173}{\it NAME\/}{\cf\char'175} creates a target named {\it NAME} for a link at the position in 
+the presentation where it is used.
+\vskip5pt
+{\cf\char'134 link\char'173}{\it NAME\/}{\cf\char'175\char'173}{\it Stuff\/}{\cf\char'175}
+makes {\it Stuff} a link to the target named {\it NAME}.
+\vskip5pt
+{\cf\char'134 weblink\char'173}{\it URI\/}{\cf\char'175\char'173}{\it Stuff\/}{\cf\char'175}

+makes {\it Stuff} a link to destination {\it filedest} in {\it file}.
+
+{\it filedest} for example can be {\cf [}{\it page} {\cf/Fit]}, with {\it page} the page number (starting at 0).
+\vskip10pt

+\SlideTitle{\hfil Concluding Remarks}
+PDF provides the possibility to include movies, and to launch applications (which could be a movie player) via clickable
+elements. The usability for a presentation depends on how to manage the player together with a full-screen display of the
+slides. Movie support is not officially included in {\cf present.tex}.
+\vskip5pt
+If you prepare a pdf-image for a presentation which is to be shown on some different computer, it would be best to
+embed fonts used in the image into the image file. For example, if you have a file {\cf image.eps}, you need to
+convert it to pdf, in order to use it with {\cf pdftex}. You can embed the fonts by
+\vskip5pt
+{\cf  ps2pdf -dEPSCrop=true -dPDFA image.eps} 
+\vskip5pt
+A look at {\cf present.tex} is recommended.
