Feed it a prezi zip and it'll give you an executable to run a webserver to serving your prezi presentation.
To convert:
./prezi-linux prezi.zip my_prezi
To run:
./my_prezi
To convert you need unzip which is the only thing that doesn't come with most modern distros that I'm aware of. To run the presentation you need ruby & rackup installed.
Could possibly do with checks in bootstrap for required deps (ruby / rackup)
