def copymode(src, dst, follow_symlinks=True, **kwargs):
    """
    Copy the permission bits from src to dst. The file contents, owner, and group are unaffected. Due to the
    limitations of Windows, this function only sets/unsets the dst's FILE_ATTRIBUTE_READ_ONLY flag based on what src's
    attribute is set to.

    If follow_symlinks is 'False', and both src and dst are symbolic links, copymode() will attempt to modify the mode
    of dst itself (rather than the file it points to).

    This function supports src and dst being either a local or UNC path. A relative path will be resolved based on the
    current working directory.

    :param src: The src file or directory to copy the read only flag from.
    :param dst: The dst file or directory to copy the read only flag to.
    :param follow_symlinks: Whether to copy the read only flag on the symlink or the target of the symlink.
    :param kwargs: Common arguments used to build the SMB Session for any UNC paths.
