[buug] dd to clone

[John de la Garza]

This kind of gets back to me wanting to use dd.  From what I see this  
is a gui to dd (and some other things like netcat).  I'm kind of in  
need of a command line tool.  I only have a shell interface to work  
with.

Although, if I play with this I may get some ideas from looking at  
what it does to image a drive.
