title: Check that an svn repository url does not exist
body: <p>I am writing a script which will add a new project in the repository, based on the name supplied by the user. Part of this involves checking that an url with the same name does not already exist on the repository.</p>
  
  <p>In the repository, all the projects of our team are stored in</p>
  
  <p><strong><a href="https://developernetwork.repo.net/svn/Projects/" rel="noreferrer">https://developernetwork.repo.net/svn/Projects/</a></strong></p>
  
  <p>Let's say that the user wants to call the project "Calculator" and runs the script. In this case, we need to ensure that the following does not already exist in the repository</p>
  
  <p><strong><a href="https://developernetwork.repo.net/svn/Projects/Calculator/" rel="noreferrer">https://developernetwork.repo.net/svn/Projects/Calculator/</a></strong></p>
  
  <p>Is there an svn command which I can use to accomplish that? Unfortunately I cannot see an appropriate command I can use in the svn documentation (<a href="http://svnbook.red-bean.com/en/1.0/svn-book.html" rel="noreferrer">http://svnbook.red-bean.com/en/1.0/svn-book.html</a>) at all.</p>
