title: What are the reference infos when using Eclipse Batch Compiler
body: <p>When reading through the <a href="https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftask-using_batch_compiler.htm" rel="nofollow noreferrer">Eclipse Batch Compiler Documentation</a> for Java, I came accross the flag <code>-referenceInfo</code> whichs description is as follows:</p>
  
  <blockquote>
    <p>Compute reference info. This is useful only if connected to the
    builder. The reference infos are useless otherwise.</p>
  </blockquote>
  
  <p>What are does reference infos? Are those infos about object references? Is there any documentation available?</p>
