>Is anyone implemented the above tool? ...

It has been extensively discussed in the past months.
You'll find abundant usage comment in the ADSM-L archives...

        The archives are also searchable from the web:
          www.adsm.org  is the most commonly used
          www.marist.edu/htbin/wlvindex?adsm-l  yields a primitive file list
                You can also email the list administrator from this page.
                (Be aware that its web server is always slow.)
