Bonjour Gilles!

I just realised yesterday that I wasn't subscribed to the list, and I missed
your message. Oops!

Anyway...

Wonderful. I haven't maintained a package in KDE before, so kick me if I'm
 not doing something properly. :-) I'm pretty excited to get involved with
 KDE, especially digiKam-related stuff, which is absolutely wonderful...

Sure, this sounds relatively simple. I'll get on this first.

Can you send imagerotate.cpp to me? I can get started from that...

Sure, if you could send me those too that would be great.

Again, sorry for the response delay. I missed your message. But don't worry
 -- I'm getting on top of things.
