title: How to set Cscope->database-> Set init directory
body: <p>I am using xcode with emacs. But everytime I start emacs, I need to
  go to menu 'CScope' -> Cscope->database -> set init Directory
  and it pick the root directory of my source.  </p>
  
  <p>And then I click 'CScope' -> Cscope->database -> set init Directory->create list and index'</p>
  
  <p>Is there anyway I can configure that in .emacs so that I don't need to do that every time i start emacs?</p>
  
  <p>Thank you.</p>
