Last time I created a presentation in Org Mode was in 2010 here.
Creating presentation in Emacs Org Mode and publishing it as Latex, PDF and HTML, is so awesome.
Here are the links to get you started:
And follow these simple steps ( I am using Ubuntu right now but the steps should be easy on Fedora too.):
Create a slides.org file as in the tutorial above:
Install Beamer class for Latex.
$ sudo aptitude install aptitude latex-beamer
And export it to PDF using «Ctrl+c Ctrl+e p» in Emacs.
Your presentation is in slides.pdf in the same folder as slides.org.
