Err, that's an _interesting_ way of replacing the '-r' option ;-)

I see 2 problems: 
- the setup is more complex than just specifying the root dir
- the user is required to know the name of the lens to apply to control file

Anyway, feel free to add these steps in the comment of Debctrl lens.

Which is more simple but still require the user to match the file name and the 
lens name.

All the best
