  * Utility used to create a manifest class path.
 25   
  * It takes, as input, a reference to a path.  It converts this
 26   
  * into a space-separated list of file names.  The default
 27   
  * behavior is to simply strip off the directory portion of
 28   
  * each file entirely.

 30   
  * <p>
 31   
  * The final result is assigned to the property.
