Libreoffice4 in wheezy? Several questions

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hello all,

I wanted to install LO4 in wheezy. I wondered, why it is in wheezy-backports 
but not in testing. Maybe the packages in wheezy-backports are too young for 
testing? 

However, I managed it by using aptitude and made sure, all dependencies are 
correct.

But I guess, there is an easier way, to update my ONLY my installed packages 
out of wheezy. In the wiki I read, you can use apt-get -t wheezy-backports 
install $package, which worked well.

And of course, i can edit the apt pinning system to give wheezy-backports a 
higher ranking. But wouldn't this affect other packages, too?

I suppose, there might be a way just to update certain packages from wheezy-
backports using the pinning system, but I fear, I can use this only for meta-
packages or directly named packages. Please correct me, if I am wrong.

And last question: If Libreoffice4 will be put into testing repo, will those 
packages then be newer than those in wheezy-backports or is this a matter of 
chance?

Thanks for your answers! This will help me to help my friends.

Best regards

Hans
