    Examples
    --------
    To align a FASTA file (unaligned.fasta) with the output files names
    aligned.* including a FASTA output file (aligned.fa), use:

    >>> from Bio.Align.Applications import DialignCommandline
    >>> dialign_cline = DialignCommandline(input="unaligned.fasta",
    ...                                    fn="aligned", fa=True)
    >>> print(dialign_cline)
    dialign2-2 -fa -fn aligned unaligned.fasta

    You would typically run the command line with dialign_cline() or via
    the Python subprocess module, as described in the Biopython tutorial.
