Dear Maintainer,

your machine-readable debian/copyright file contains a files paragraph 
with a missing License:-field:

  Files: debian/*
  Copyright: 2003, Mark Purcell <msp at debian.org>
             2012, Michael van der Kolff <mvanderkolff at gmail.com>

Could you please add a correspondig license entry for your files?

Thanks!
   Thorsten
