Using bzr for packaging - RFC: bzr unpack

[Daniel Holbach]

Hello everybody,

after a good discussion with Alexander Sack and Michael Vogt, I hacked a
bit on a tool called bzr unpack. It's going to help with debian/
packging in bzr. What it does is in a debian/ packaging branch:

      * get the tarball
      * unpack the complete source tree in /tmp/something
      * open a subshell
      * lets you make changes to it
      * once you leave the subshell, it will apply the changes to your
        debian/ packaging

"Demo":

bzr branch: http://daniel.holba.ch/bzr-unpack/
Package: http://daniel.holba.ch/bzr-unpack_0.1.0_all.deb


Please play with it and let me know what you think about it, it's not on
Launchpad yet, as I don't know if the name is going to stay like that
and if it shouldn't go into bzrtools or something else.

I really hope this is going to change how we integrated bzr into our
packaging workflow and will make it easier for new contributors.

Have a nice day,
 Daniel
