+     "The package creates slides for on-screen presentations based on PDF
+features without manipulating TeX's typesetting process.  The presentation
+flow relies on PDF's abilities to display content step by step.  Features
+include:
+
+@itemize
+@item Free positioning of anything anywhere in painted areas on the slide, as
+well as in the main text block;
+@item Numerous attributes to control the layout and the presentation flow,
+from TeX's primitive dimensions to the visibility of steps;
+@item Feature inheritance from global to local settings, with intermediate
+types; Basic drawing facilities to produce symbols, e.g., for list items or
+buttons;
+@item Colours, transparency, shades, and pictures;
+@item Navigation with links, pop-up menus, and customizable bookmarks;
+@item Easy switch between presentation and handout; and PDF transitions.
+@end itemize
+
+Besides the traditional documentation, the distribution includes visual
+documentation and six demo presentations ranging from geometric abstraction to
+classic style to silly video game.")
