title: How to find new undelivered files for a given UCM "stream"
body: <p>We use UCM for development. We create streams under streams, like this </p>

  <p>Question is how to find new files in a given stream. </p>
  
  <p>In the example "<code>feat1</code>"  would have new files relative to its parent <code>lis1</code> (lis=local integration stream). The new files could be from "<code>feat1</code>" or its child streams like "<code>developer1</code>". How could I identify new files in <code>lis1</code>?</p>
  
  <p>One option is to create dynamic views on a stream (say feat1) and its parent stream(lis1) and take diff and figure out files new in the child stream.  </p>
  
  <p>Another option is to use <code>cleartool deliver -preview</code> and get list of versions and then somehow (I do not know it yet) figure out the list of files.<br>
  The problem is the child stream is not necessarily rebased to its parent, and we enforce a "rebase to latest baseline before delivery" rule.</p>
  
  <p>I hope there is a better and correct way :)</p>
