title: Interpreting eclipse .classpath file. What does 'kind="con"' and 'exported="true"' mean?
body: <p>This is the eclipse <code>.classpath</code> file of the eclipse plugin program that I downloaded. </p>
  
  <p>I think that <code>kind="src"</code> and <code>kind="output"</code> is pretty straight forward, as they means the where the source java files and compiled class files are located. </p>
  
  <p>The <code>kind="lib"</code> seems to indicate the jar files the plugin is referencing, but I have something that I'm not sure about. </p>
  
  <ul>
  <li>What does the <code>kind="con"</code> mean? </li>
  <li>What is it for the <code>exported="true"</code>? I think in order to use this plugin, all the jar files that the plugin refers to should be exported, but only some of them are exported.</li>
  </ul>
