[Foo2zjs-maintainer] Architecture-independent files: CRDs and PPDs

[Luca Capello]

Hi Michael!

I am sorry for the very long delay in my reply: while I was quite busy
when I received your mail, for some unknown reason I missed it and I
have recently found it in my INBOX...

My new plan is to upload 20090908dfsg-2 soon, closing three bugs:

1) <http://bugs.debian.org/517957>, firmware in /lib/firmware/hp

2) <http://bugs.debian.org/550268>, Luca Bedogni no more in Uploaders:

3) <http://bugs.debian.org/558978>, fix the udev rules file

Then, once this version will have reached testing, I will upload a new
upstream version, introducing the two new binary packages and
synchronising the Debian package with Ubuntu.

Thx, bye,
Gismo / Luca
