This is a Vim plugin that shows a proxy icon on the title bar for the file you're editing when running on Terminal.app on OS X El Capitan.
The best way is to use pathogen.vim to handle your Vim plugins.
Once you have pathogen.vim installed, you may clone this repository into
~/.vim/bundle
:
$ cd ~/.vim/bundle
$ git clone https://github.com/mernen/vim-terminaldocument.git
The simplest way without depending on other plugins is to copy
terminaldocument.vim (just this file) into
the ~/.vim/plugin
directory.
