title: Revert back to older version in TortoiseSVN and Commit
body: <p>I use TortoiseSVN tool for the version management of my project. Till now, I have committed for 17 times. Now, I want to go back to 10th revision and start to make changes to the project and commit. </p>
  
  <p>I have tried to do so by getting the 10th revision of the project and make changes. And then, I tried to commit. This says, "You are not having the latest version to commit" and it asks me to update the project to the head revision.</p>
  
  <p>Is that possible to remove the last 7 commits and make the 10th revision as the head revision? 
  Or
  Is that possible to get the 10th revision and make changes and then commit to SVN?</p>
