Don't forget to install all the vim bundle submodules:

  git submodule update --init

Then link up as many files as you want to use...

  cd ~
  ln -sf config_files/vimrc ~/.vimrc
  ln -sf config_files/vim ~/.vim
  ln -sf config_files/irssi ~/.irssi
  ln -sf config_files/gvimrc ~/.gvimrc
  ln -sf config_files/ackrc ~/.ackrc
