Upstream tarball repackaged
===============================================================================
As the upstream tarball has been updated since it contained a debian directory,
here are the following commands to get the new debian tarball ds.orig.tar.gz:

- From the build directory: run ./debian/rules get-orig-source

- Otherwise:

    $ wget http://search.cpan.org/CPAN/authors/id/F/FR/FRAJULAC/Net-IPv4Addr-0.10.tar.gz
    $ tar -xzvf Net-IPv4Addr-0.10.tar.gz
    $ cd Net-IPv4Addr-0.10
    $ rm -rv debian
    $ cp MANIFEST MANIFEST.old
    $ sed '/^debian/d' MANIFEST.old > MANIFEST
    $ rm MANIFEST.old
    $ cd ..
    $ mv Net-IPv4Addr-0.10 libnetwork-ipv4addr-perl-0.10.orig
    $ tar cfC repacked.tar . libnetwork-ipv4addr-perl-0.10.orig
    $ gzip -9 < repacked.tar > libnetwork-ipv4addr-perl_0.10.ds.orig.tar.gz
    $ rm repacked.tar
    $ rm Net-IPv4Addr-0.10.tar.gz

Quilt
===============================================================================
This package uses quilt to manage all modifications to the repackaged tarball.
So, you may have a look at the /usr/share/doc/quilt/README.source file to get 
further information on how to use it.
