title: Recursive svn upgrade in local filesystem (Win32)
body: <p>There is a need to recursively run svn upgrade in certain directory in filesystem, ignoring non-svn subdirectories:</p>
  
  <pre><code>C:\a&gt;svn upgrade
  C:\a\b&gt;svn upgrade
  &lt;skip non-svn dir&gt;
  C:\a\b\c&gt;svn upgrade
  ...
  </code></pre>
  
  <p>This means we need to run svn upgrade command in every folder that has <code>.svn</code> inside it. How this can be done in win32? Found <code>for d in find . -name .svn -type d; do svn upgrade $d/..; done</code> routine for posix OS.</p>
