def append(path, *args, **kwargs):
    '''
    .. versionadded:: 0.9.5

    Append text to the end of a file

    path
        path to file

    `*args`
        strings to append to file

    CLI Example:

    .. code-block:: bash

        salt '*' file.append /etc/motd \\
                "With all thine offerings thou shalt offer salt." \\
                "Salt is what makes things taste bad when it isn't in them."

    .. admonition:: Attention

        If you need to pass a string to append and that string contains
        an equal sign, you **must** include the argument name, args.
        For example:

        .. code-block:: bash

            salt '*' file.append /etc/motd args='cheese=spam'

            salt '*' file.append /etc/motd args="['cheese=spam','spam=cheese']"
