I have the common situation, that I want to build my package "foo"
against a library "bar" which has not yet hit the archive, but I
have the .deb for the new library available.
To achieve this, I could create a local mirror containing the
bar .deb and add this directory for building foo through the
--other-mirror option. However this is somehwat complicated.
I would like to have a simpler way of doing this, something like:
    pbuilder build --with-additional-packages="libbar-dev_0.1_i386.deb"


Thanks,

Ben
