title: SVN Prevent Files on Branch from Changes
body: <p>I'm trying to develop a branching structure in a project where we have release branches for each environment we release to (QA, Staging, Production). I have created these 3 branches with their environment-specific files/code. My plan is to merge in changes from the development trunk to these release branches, but I don't want to overwrite the environment-specific files/code. Can I simply 'lock' these files to prevent them from being updated when I do a merge into the release branch?</p>
  
  <p>Possibly there's a better scenario for our release workflow out there... please let me know if I'm on the wrong track.</p>
  
  <p>Thanks!</p>
