I am using MacVim:
:version VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Aug 10 2013 17:49:20) MacOS X (unix) version
I've executed :version in vim (to check what patches I had installed) and noticed the following two lines part of the output:
user vimrc file: "$HOME/.vimrc" 2nd user vimrc file: "~/.vim/vimrc"
What is the 2nd user for, and how would you use it?
I've found and read this question:https://apple.stackexchange.com/q/34996/10733,
but the answer shows how to integrate the ~/.vim/vimrc into .vimrc.
I also did the following search in google which did not yield anything interesting: 2nd user in vim and ~/.vim/vimrc, and how to use ~/.vim/vimrc
