RePresent is a project mainly written in Emacs Lisp, it's free.
Emacs major mode to create presentations
A simple Emacs major mode that can be used to make presentations.
The idea is to have different "kinds of slides" (like source code listings, regular bullet points etc.).
To try it out, simple load the rePresent-mode.el
file and then use
the rePresent/load-file
command to load the sample-presentation.el
file. It will create two buffers (each of which is a slide). You can
use the PgDn, PgUp keys to incrementally display the bullets.
Features planned.
