title: How to svn:ignore a file that is under source control?
body: <p>The <em>svn:ignore</em> property ignores files that aren't under source control, so they don't come up in <code>svn status</code> with a <code>?</code> (they don't come up at all, and are ignored also if you do an <code>add</code>)  </p>
  
  <p>But what if I want to ignore a file that is under source control? <em>svn:ignore</em> won't ignore it.<br>
  For example, what I want to do is set a configuration file, add it to svn, so it's there when the system has to be deployed on a test or live server (it's a web app) but for local environment development, I need to modify the config file to set it up with my local settings.  </p>
  
  <p>But I don't want this updates to be commited, so, how can I do?  </p>
  
  <p><code>svn delete</code> will just remove them from the repository and when doing a <code>svn update</code> on the test server, it will delete the config file, that's not what I want.</p>
