A man's home (directory) is his castle, so don't leave home with out it. Homesick is sorta like rip, but for dotfiles. It uses git to clone a repository containing dotfiles, and saves them in ~/.homesick. It then allows you to symlink all the dotfiles into place with a single command.
Gemfile gem 'homesick', '~> 0.8.1'
install gem install homesick -v 0.8.1
