title: Change .emacs directory in Ubuntu
body: <p>Currently my .emacs file is found in /home 
  So is my .emacs.d folder and I suppose some other files like diary, notes etc will be created in this folder. </p>
  
  <p>I find this really messy and I want all my emacs related files(including the .emacs) and folders in a single folder, say /home/EmacsHome</p>
  
  <p>How do I do that in Ubuntu 12.04? In windows I did this by setting an environment variable HOME to the path of EmacsHome. But, in Ubuntu, the HOME variable will be used for several other programs as well, so I dont want to change that. </p>
