title: How to switch between multiple vim configurations with a command or local vimrc files?
body: <p>I work in several groups, each of which has its own tab/indentation/spacing standards in C.</p>
  
  <p>Is there a way to have separate selectable VIM configurations for each so, when I edit a file, either:</p>
  
  <ul>
  <li>I do something like <code>set group=1</code> to select a configuration</li>
  <li>a local .vimrc that lives in the working directory is used to set the configuration automatically</li>
  </ul>
