title: How to auto versioning in Git with XCode 4?
body: <p>I am a SCM newbie, but I just need some basic things for version control.</p>
  
  <p>I am using Git in XCode 4.</p>
  
  <p>the questions are :</p>
  
  <p>How can I automatically give my project a versioning number (such as 1.1.2) when I commit it to the local Git repositories?</p>
  
  <p>Is Git's versioning number meant to be associated with my app releasing number? I mean for example, if my working copy's version is 1.2.3 in Git, then will the version in my info.plist be changed to 1.2.3 as well?</p>
  
  <p>Thanks</p>
