title: Diff tool that allows saving the compare markup
body: <p>Is there a diff tool that allows saving of the compare markup?</p>
  
  <p>To clarify, I would like to save the actual comparison of the two files that shows the differences to send to someone for review.</p>

  <p><strong>EDIT</strong></p>
  
  <p>Lots of good answers here. In my case I already had a copy of <a href="http://scootersoftware.com" rel="nofollow noreferrer">Beyond Compare</a> but didn't see the option. Thanks to John Saunders for pointing out the feature. It's "Session...Text Compare Report..." BTW.</p>
  
  <p>My question was not specifically about Beyond Compare, so I am going to accept the answer that currently has the most up votes.</p>
