I am working on a couple Rails apps on my local machine - but would love to be able to upload them to my web server for the client to see and work on them as we near completion.

Is there a good tutorial for publishing Rails apps on a webserver? I have my own server, so I can install anything neccessary. I just don't know quite how to upload/move the application.

There are a lot of files there - do they all need to be moved? Is there some kind of export with just the code neccessary to run on a production server?
