Inside-out packaging

[Sam Vilain]

So far the emphasis seems to have been on keeping a branch of the main
project, and a branch for the debian packaging information.

However, for some packages, it might be better to have a module arranged
like this:

   debian/
   upstream/

Where upstream is a submodule that points to an upstream repo.  This
also keeps the debian changelog nicely away from the upstream one.

Anyone experimented with this?

Sam.
