This is just my personal VIM and zsh configuration.
I'm used to have my dotfiles in my DropBox since I use more than one Mac for deveoplment.
For proper symlinking and faster setup I use the little bash script you can find in:
Please backup your own files, if you want to use it too. (NOTE: This will override all your dotfiles like .vimrc, gvimrc, zshrc, hgrc and so on)
I use Vundle for managing my plugins, so if you want to update the bundles use
:BundleInstall
