These are the files I use to configure my shell just the way I like it.
Original credit/inspiration goes to Erik Michaels-Ober. Without him, I wouldn't be where I am today.
gem install thor
git clone git://github.com/ahegyi/dotfiles
cd dotfiles
thor dotfiles:install
Before and after installing, try running thoughtbot's laptop script to set up your comp. Before to get the basics, after to get the stuff in laptop.local.
**Don't forget to set your git username and e-mail in gitconfig!
These files are an amalgamation of wisdom collected over the years, the sources of which are too numerous to list. The idea to put them in a repository with an install script was taken from Ryan Bates.
