Thank you for the note, sorry for the late response.
Actually the code was first written in 2002 and I modified in 2004. I can't remember touching this code after that. When I wrote the code there weren't many tools for this purpose and I wrote it for personal use.
This tool may have little value now as there are many tools available. But that was not the case when it was written. 🙂
