    @todo
    Problem: $ChildCount can be zero!
    This happens if you have a container that does not
    unpack to a directory.  For example:
    file.gz extracts to archive.txt that contains a license.
    Same problem seen with .pdf and .Z files.
    Solution: if $ChildCount == 0, then just view the license!
    $ChildCount can also be zero if the directory is empty.
