00011 class ClustalwCommandline(AbstractCommandline):
    """Command line wrapper for clustalw (version one or two).

    http://www.clustal.org/

    Example:

    >>> from Bio.Align.Applications import ClustalwCommandline
    >>> in_file = "unaligned.fasta"
    >>> clustalw_cline = ClustalwCommandline("clustalw2", infile=in_file)
    >>> print clustalw_cline
    clustalw2 -infile=unaligned.fasta

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