PresTiMeL is a tool to create a presentation out of a XML-file. For each slide, PresTiMeL will create one (or a set of) HTML-file(s), which can be shown in a Web browser of your choice. Cascading Stylesheets (CSS) are used, to define how big a text-item has to be, which font and color it should have, etc. So you will need a Web browser, which supports CSS, like Netscape 4.* or Internet Explorer 4.*.
Optional, it's possible to create a LaTeX-file, which can be used to create and print some handouts of the presentation.
