[Bug-wget] Please help: resume mirroring without clobbering

[Sascha Mantscheff]

This list is called bug-list, but since I did not find any support list, 
maybe someone could help me here:

I have mirrored a site with "wget -w 1 -nc -r <site>". The process was 
interrupted. Now I'd like to resume it without downloading the whole 
site again. When I start the process on the site's root page, mirroring 
stops after the first page, though, since all the links from this 1st 
page are already retrieved and on the local drive.
Is there an option so that wget reads the already retrieved files again 
and checks for links in them which still would have to be mirrored?

Thanks for you help.
