title: moving eclipse (not the workspace) to a different directory
body: <p>I recently installed Mars Eclipse.  I took the default install directory, c:\users\myname\eclipse\java-mars.  Everything is installed and some projects checked out and working.</p>
  
  <p>But I now wish I had installed it in c:\eclipse\java-mars.  I am wondering how to change it?  Please note I did searches but they all are how to move your workspace, not how to change the installation directory.  My workspace can stay where it is.  I suppose I could uninstall and delete everything, and reinstall into a new directory, but that is a lot of hassle.</p>
