Your English is excellent. :)

Please create an account on on alioth and Christophe will add you to
our team. Then you will be able to commit your changes to our svn
repository.
We'll then test it and upload.

The other option is that you send us a patch, that we just apply and
upload -- but the first option is preferred, as you'll probably find
some other things that you coud easily fix.

Thanks a lot,
Ondrej
