title: Anyone know of a good free patch creator?
body: <p>Does anyone know of a good patching program that is free? You know, one that can take a directory with your old program in it and compare it to a directory with your new version, and spit out a patch that is only the difference between the two?</p>
  
  <p>Also, I am looking for something that can patch the entire directory, not just one exe.</p>
  
  <p>EDIT:
  Thanks for the answers, but I am looking for an end user patch for product updates. Nothing to do with the source.</p>
