" Pathogen.vim is a plugin by tpope available here: https://github.com/tpope/vim-pathogen
"    It allows for vim plugins be easily installed in their own private
"    directories.
"
"    To install pathogen, (Assuming vim is installed), create an autoload and
"    bundle directory: 
"      	mkdir -p ~/.vim/autoload ~/.vim/bundle
"    Then curl the file into autoload
"
"    		curl -so ~/.vim/autoload/pathogen.vim \
"        https://raw.github.com/tpope/vim-pathogen/HEAD/autoload/pathogen.vim
"    Finally, the following line in .vimrc enables pathogen
call pathogen#infect()
" Now, to install a vim plugin, copy the repository to ~/.vim/bundle/<plugin>
