This is the Vim configuration that I like to use. Do with it what you will.

To install on Ubuntu, move the .vimrc file to ~/ (your home directory) (back up yours if necessary!) and move the CaseyCustom.vim file to the ~/.vim/colors/ directory.

Note that you may need to create the ~/.vim/colors/ directory if it doesn't exist; just use: mkdir -p ~/.vim/colors/
