title: VIM: Overwriting system vimrc
body: <p>I work on multiple MAC OS X systems, which do not save changes after log out. As you know VIM is on every new mac, just type in vim in the terminal. I always bring my vimrc file with me, and the problem is that every single time I start vim i have to load it with <code>:so</code> command.</p>
  
  <p>I want to use the fact that vim is available on every unix, but I also want to take advantage of the nifty integration with the terminal for doing quick tests, I just switch back to the terminal, but for that I need to close vim. When I reopen it, I again have to load the vimrc. And I am a newb, I don't even have plugins yet...</p>
  
  <p>I want to keep the integration with the terminal and only develop a super quick way of introducing my changes to vim. Think of the conditions as if though you are sitting on newly installed operating system.</p>
  
  <p>Thanks !</p>
