title: .classpath contents update in eclipse
body: <p>I downloaded an eclipse project that has a .classpath which has class entries that need to be updated. </p>
  
  <p>What does this do exactly? 
  Can I change the content of the .classpath in eclipse? </p>
  
  <p>I opened <code>User Libraries</code> in eclipse expecting it to have the same content as .classpath, but there is nothing in it.</p>
