title: Is there a way to change a SVN users username through the entire repository history?
body: <p>When my team first started out with SVN we all just used our first names when committing to the repository, however, now that our team has grown, we are running into issues because we just hired a second <code>Mike</code>.</p>
  
  <p>What we would like to do is change everybody's usernames to be the same as the username on their computer (first name initial + last name).  The issue that I'm seeing is that the SVN history will still show the old usernames on commits.</p>
  
  <p>Is there a tool out there for changing usernames throughout the entire history of a repository?</p>
  
  <p>For example, I would like every commit that is currently attributed to Mike to change to msmith, all the way back to revision 1.</p>
  
  <p>My first thought is that I'll have to do some parsing and processing on a dump file, but a tool would be nice.</p>
