title: How do I list all versions of a gem available at a remote site?
body: <p>I'm trying to find out all the remotely available versions of a specified gem.</p>
  
  <p>I tried using:</p>
  
  <pre><code>gem list rhc --remote
  </code></pre>
  
  <p>But it shows:</p>
  
  <pre><code>*** REMOTE GEMS ***
  rhc (0.84.15)
  rhcp (0.2.18)
  rhcp_shell (0.2.12)
  </code></pre>
  
  <p>Any ideas?</p>
