title: How to remove old SVN revisions
body: <p>Our SVN repository is approaching 0.5 GB. We have nowhere near that amount of code in our production system.</p>
  
  <p>Is it possible to remove old revisions. I tried <code>svn dump</code> with a beginning revision number, but to no avail. I couldn't import that into a clean SVN repository.</p>
  
  <p>We don't need the history over a year old.</p>
  
  <p>Any ideas?</p>
