I use thoughtbot/dotfiles as the
foundation of my personal configuration. These files are the .local
modifications that build on top of the foundation.
git clone git@github.com:dcalhoun/dotfiles.git ~/.dotfiles
~/.dotfiles/install.sh
Most of my configuration is small changes on top of thoughtbot's dotfiles. They have a great series of blog posts about dotfile configuration at their blog.
