title: Install multiple version of Vim, and make each use different .vimrc file, respectively
body: <p>Make it on Linux. The reason to use more than one version of Vim, is because one version would be heavily hacked, for Lisp jobs.  I want separate it and make it use it's own .vimrc file as well.</p>
  
  <pre><code>/usr/bin/vim   use -&gt; ~/.vimrc
  /my/vim        use -&gt; ..../another_vimrc
  </code></pre>
