vimrc-fu to bootstrap vundle This code will bootstrap vundle and run BundleInstall when vundle is missing. It is non-interactive thanks to a healthy sprinkling of :silent, and assumes that Git is installed.

	filetype off
	set rtp+=~/.vim/bundle/vundle/
	let s:bootstrap = 0
	try
	call vundle#rc()
	catch /E117:/
	let s:bootstrap = 1
	silent !mkdir -p ~/.vim/bundle
	silent !git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle
	redraw!
