Helper script for backport?

[Carsten Aulbert <carsten.aulbert@aei.mpg.de>]

Hi all,

I'm about to need to backport a couple of packages from squeeze for our
collaboration (if it helps I can  make them available here as well),
e.g. r-cran-xtable is requested currently.

I can easily build it nicely via pbuilder/cowdancer however I need to
add ~lenny1 or something like this to the version numbers and also
adding something to the changelog (I think). Has anyone a set of helper
scripts doing this automatically (much like the early parts of Ubuntu's
prevu?)

Cheers

Carsten
