title: Clearcase mkelem without checkout
body: <p>I have a question regarding ClearCase. From the documentation of the <code>mkelem</code> command I read:</p>
  
  <blockquote>
    <p>The mkelem command creates one or more new elements. <strong>By default, a new element can be created in a directory only if that directory element is checked out.</strong> mkelem appends an appropriate line to the directory's checkout comment.</p>
  </blockquote>
  
  <p>Why is this the case? And, as it says by default, how do I change this default option? I couldn't find anything about this in the doc.</p>
