Not sure about this link here. I don't trust it.
Also if this is a tool there are already several included in BT. So not sure what this will bring to the table.
Try wepbuster, aircrack-ng, gerix-wifi etc.
OP really if you want the dev's to add a tool to the repo you should probably do better than the above post. I mean try explaining the benefits to the pentesting community for having this tool.
