It is common to use a computer tool (ex: PowerPoint [1]) in order to prepare a presentation.
The material generated by the tool is a sequence of slides where each slide consits of:
one title
many topics, organized in a hierachical way.
In this paper we present a "lecture generator" tool that transforms a single text into HTML pages (slides) to be used in a lecture. See [2] for testing.
Our approach is simpler than "PowerPoint":
The input text has a very simple notation that can be created in any text editor.
The output,the HTML pages, are "lighter" (or small) documents that can be seen in any browser.
