    Parameters
    ----------

    instr : basestring
        The string to be indented.
    nspaces : int (default: 4)
        The number of spaces to be indented.
    ntabs : int (default: 0)

        Whether to scrub existing indentation.  If True, all lines will be
        aligned to the same indentation.  If False, existing indentation will
        be strictly increased.
