This is the Emacs setup I use everywhere. The structure of the configuration is heavily influened by magnars. I highly recommend checking out his configuration and the Emacs Rocks screencast if you are interested in learning more about tailoring Emacs to your needs.
If you want to use this configuration yourself, simply clone this repository into your home directory.
cd ~
git clone git://github.com/rcdickerson/.emacs.d.git
The first time you open Emacs, some packages will be automatically installed from MELPA to your ~/.emacs.d/elpa directory.
