title: "Overwrite merge" using svn - is it even possible?
body: <p>Using Subversion I have two different trunks that contains essentially the same content, but one is less frequently updated than the other. For simplicities sake, let's call them "old trunk" and "new trunk".  </p>
  
  <p>On a regular basis I want to replace <em>everything</em> that exists in "old trunk" with that in "new trunk". Essentially, what I want is to "copy" everything and replace what exists.</p>
  
  <p>If I try to merge, I end up with some of the files that were deleted in "new trunk" as a pragmatic merge between the two trunks. This is not what I want.</p>
  
  <p>Previously I've used to manually copy and replace each subfolder, starting by deleting any unwanted files in the old version. This is a painstaking process and should be replaced by a "overwrite merge" as it is called in Clearcase.</p>
  
  <p>Is there a way to accomplish this without manually going through each and every folder?</p>
  
  <p>Edit: This is not an ideal setup, but due to circumstances out of my control it is as it is. I'd still like to know the answer to my core question: is it possible to create an overwrite merge?</p>
