title: How to change the $HOME directory in Git
body: <p>I would like to know, since I've been looking quite some time on how to do this, atleast in this community.  would like to know how to change the $HOME directory in a Mac OS X Lion, in Git.</p>
  
  <p>In other words, how do I make it so that my global user settings are saved in a folder like git and not right inside the main user folder? Or is it already like that? I basically want to keep a centralized place for all my files and stuff that I use in Git (for example, a <em>.gitmessage.txt</em> file, if I'm not mistaken, this shouldn't be hidden since it's a TXT file).</p>
  
  <p>If you need more info don't hesitate to ask.</p>
