To install:

git clone ssh://git@github.com/eppsilon/dotfiles .dotfiles
cd .dotfiles
git submodule update --init --recursive
./install.sh

For sensitive or environment-specific stuff, add a .user file to override the main one. (Ex: .gitconfig.user.)

This repo depends on Prezto for an excellent set of ZSH customizations. It also takes inspiration from YADR, a much more extensive collection of dotfiles.
