title: Perforce change list size
body: <p>Someone is submitting change lists that are using up a lot of disk space on our Perforce server. I want to find the size of recent change lists so I can track down where this is happening. Is there a way to do this?</p>
  
  <p>p4 sizes shows the size of files in the depot but doesn't show history. I suppose I can run this periodically and see what's growing, but I would like to look back in time.</p>
  
  <p>p4 describe shows what's in change lists, but doesn't show the size of the files in the change list.</p>
