    """ Function that can be used as shutil.copytree() ignore parameter that
    determines which files *not* to ignore, the inverse of "normal" usage.

    This is a factory function that creates a function which can be used as a
    callable for copytree()'s ignore argument, *not* ignoring files that match
    any of the glob-style patterns provided.

    ‛patterns’ are a sequence of pattern strings used to identify the files to
    include when copying the directory tree.

    Example usage:

        copytree(src_directory, dst_directory,
                 ignore=include_patterns('*.sldasm', '*.sldprt'))
