5" Install in ~/.vim/autoload (or ~\vimfiles\autoload).
6"
7" For management of individually installed plugins in ~/.vim/bundle (or
8" ~\vimfiles\bundle), adding `execute pathogen#infect()` to the top of your
9" .vimrc is the only other setup necessary.

23" on versions of Vim without native package support.
