Bruce, the Presentation Tool is for people who are tired of fighting with presentation tools. Presentations are composed (edited) in plain text files. In its basic form it allows text, code, image, interative Python sessions and video.

It uses pyglet to displays via OpenGL and handle multi-head (the most common presentation setup) so you can have the presentation displayed on a projector while your laptop displays the original presentation source shown alongside (showing notes and animation or presentation cues).

.. load-style:: big-centered

Text displayed centered on the default white background.


A new page, separated from the previous using the four

Ut enim ad minim veniam.

A Page Title

Pages may optionally have titles which are displayed
centered at the top by default.
