1. Introduction

The purpose of presentation software is to enable someone to impart information to an audience in an interesting and effective way.

This is usually done in the form of a visual presentation that the audience views along with a running commentary from the presenter.

To this end, a good presentation package has the capability to handle advanced features including sound, images, animation, slide transitions, hyperlinks, hotspots and navigation buttons as well as plain text of course.

Each of these features are intended to add something to the quality of the presentation.
