Sorry Keith and all others for the noise, I'll try to not read my mails
when I am tired next time.
The release notes have a pseudo-packages. You can browse some of its
issues on our bug tracking system, or contact directly its maintainer
for your very good question. Lastly, it seems that its sources are
availables on cvs.debian.org, so you can monitor the changes there as
well (if it is the correct repository).
Have a nice day, and thank you very much for your help,
Tsurumi, Kanagawa, Japan
