sent - 1-3 main

sent does not need LaTeX, libreoffice or any other fancy file format,
it uses plaintext files to describe the slides and can include images
via farbfeld. Every paragraph represents a slide in the
presentation.
.
The presentation is displayed in a simple X11 window. The content of
each slide is automatically scaled to fit the window and centered so
you also don't have to worry about alignment. Instead you can really
concentrate on the content.
