Both Thoughtbot dotfile and its' dependent RCM
Clone onto your laptop in a golang-like src hierarchy
mkdir ~/src
mkdir ~/src/glennr
cd src/glennr/
git clone git://github.com/glennr/dotfiles.git
To make sure rcm picks up these local customizations, you need to create a symlink from ~/dotfiles-local to this repo dir i.e.
ln -s ~/src/thoughtbot/dotfiles dotfiles
And rerun rcup
env RCRC=$HOME/dotfiles/rcrc rcup
