title: openSUSE:Build Service - Way to find all link packages
body: <p>I configured OpenBuildService with version 2.5.
  And I have project called <code>TestProject</code> with 100 packages.
  <strong>The question is:</strong> How can I list up all <code>link</code> packages?
  I know the API to check whether the package is linked or not, </p>
  
  <pre><code>http://myserver:81/source/TestProject/samplepackage?rev=latest
  </code></pre>
  
  <p>I can't find the API to list up whole linked package list.</p>
