title: need equivalent python command for p4 describe
body: <p>I need equivalent for <code>p4 describe #cl</code>, in p4 python.</p>
  
  <p>However, running the same command <code>p4.run_describe("#cl")</code> using p4python. I get dict:</p>
  
  <pre><code>[{'client': 'NonDev1408-Dev', 'digest': ['E41FFB100C73F7B443EE8DE7A0DD966C'], 'desc': 'Merging //ATTE/1507_SWP122 to OCX Main (//ATTE/1408-Dev)\n', 'type': ['text'], 'fileSize': ['33067'], 'status': 'submitted', 'rev': ['49'], 'depotFile': ['//ATTE/1408-Dev/cust/oms/bb/cord9src/src/main/java/amdocs/oms/cust/osact/foundation/NegotiateServiceConnection.java'], 'action': ['integrate'], 'user': 'mohitc', 'change': '243446', 'time': '1432731112', 'path': '//ATTE/1408-Dev/cust/oms/bb/cord9src/src/main/java/amdocs/oms/cust/osact/foundation/*', 'changeType': 'public'}]
  </code></pre>
  
  <p>Instead I want output like given by <code>p4 describe 243446</code> that is, I want diff changes between the affected files:</p>
  
  <pre><code>Change 243446 by mohitc@NonDev1408-Dev on 2015/05/27 15:51:52
  
          Merging //ATTE/1507_SWP122 to OCX Main (//ATTE/1408-Dev)
  
  Affected files ...
  
  ... //ATTE/1408-Dev/cust/oms/bb/cord9src/src/main/java/amdocs/oms/cust/osact/foundation/NegotiateServiceConnection.java#49 integrate
  
  Differences ...
  
  ==== //ATTE/1408-Dev/cust/oms/bb/cord9src/src/main/java/amdocs/oms/cust/osact/foundation/NegotiateServiceConnection.java#49 (text) ====
  </code></pre>
  
  <p>Is there any other way to produce the same output using p4python?</p>
