++
++      * Also run lintian on the .dsc file to check the source itself.
++
++      * Fix the direct usage of ar | tar etc to get the copyright file
++      and use dpkg-deb, which is made for this and makes us able to
++      process data.tar.bz2 (or whatever format it will be in the
++      future).

 +2007-12-21  Joerg Jaspert  <joerg@debian.org>
 +
 +      * Remove the (now useless) check for a pre-depends on dpkg for
 +        binaries that contain bzip2 compressed data tarballs.
