Subject: [1/2] UBUNTU: make module-inclusion selection retain the left overs
Date: Fri, 16 Sep 2011 03:45:59 -0000
From: Andy Whitcroft <apw@canonical.com>

Move module inclusion to a model when the non-included modules
are retained.  This allow two things:

1) processing can now be applied iterativly to carve out any number of
   sub-packages, and
2) we can package the 'remaining' modules.
