   #
   #   This file contains code to recursively process
   #   a Directory.  This is a bit more powerful
   #   than File::Find in that we pass the full
   #   stat info to the processing function.
   #     For each file in the specified directory subtree, 
   #   The user's Code reference is invoked for all files, regular and otherwise
   #   except:
   #      ., ..
   #
   #  Parameters:
   #     code_ref    - Code reference, invoked for each file in the tree.
   #                   as follows:  CodeRef(directory, name, statinfo)
   #                   directory the path to the directory holding the file.
   #                   name      the name of the file within Directory.
   #                   statinfo  a reference to the stat of the file.
   #     start_dir   - The starting point of the directory walk.
   #
   # NOTE:
   #   Yes, we could have just used File::Find, but since we have to get the
   #   stat anyway, this is actually simpler, as File::Find would have gotten
   #   the stat to figure out the file type and then we would have gotten it
   #   again.
