title: Easy way to get SVN repository URL for ant build
body: <p>I'm in the sad process of migrating a Mercurial repository to Subversion. Our ant build grabbed the version of the working copy and stuck it in the build product using <code>hg id -i</code>, for purposes of traceability. This global ID is all you need to know to track down the version that was built.</p>
  
  <p>Of course, it's not that easy with SVN. I know how to get the version of the working copy (or, <em>ahem</em>, range of versions in the WC) using <code>svnversion</code>, but that alone doesn't tell you the full story: you need to know which branch or tag you're on.</p>
  
  <p>Is there an easy way to grab the repository URL corresponding to a WC path? What I want is the 'URL' line that's returned from <code>svn info</code>, but I really don't want to parse multi-line output to get it. There <em>has</em> to be an easy way to get just that information back.</p>
  
  <p>Doesn't there?</p>
  
  <p>I miss my DVCS. :(</p>
