title: Add files to an xcode project from the script
body: <p>I want to add libraries and some testcase script files to my xcode project. I've gone through some links which shows a way of doing it from the shell script. </p>
  
  <p>But the problem is "I don't want to use xcode GUI even for adding the script to the project". I'm building the app from commandline tool xcodebuild.</p>
  
  <p>Thanks.</p>
