title: P4Merge-Equivalent for git
body: <p>I am used to work with Perforce and find that their graphical tool <a href="http://www.perforce.com/product/components/perforce_visual_merge_and_diff_tools" rel="nofollow">P4Merge</a> is very handy, esp. for side-by-side comparison. Is there a similar (graphical) tool for <em>git</em>? A Mac solution would be ideal.</p>
  
  <p>I know I can manually set up my <code>git diff</code> to launch P4Merge. However, I am looking for something more git specific.</p>
  
  <p>Thanks.</p>
  
  <p>PS: <a href="http://mac.github.com/" rel="nofollow">GitHub for Mac</a> is really good but the file comparison is done not side-by-side.</p>
