=head1 NAME

dpt-repack -- repackaging helper
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<dpt repack> --upstream-version I<version> I<downloaded file>"
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<dpt repack> helps creating repackaged tarballs, suitable for feeding
|
|
L<dpkg-source(1)>.
|
|
|
|
Work is commenced in three stages:
|
|
|
|
=over
|
|
|
|
=item
|
|
|
|
B<dpt repack> unpacks the provided upstream tarball.
|
|
|
|
=item
|
|
|
|
F<debian/repack.local> is sourced to remove unsuitable content.
|
|
|
|
=item
|
|
|
|
B<dpt repack> packs the sources again, under a suitable file name in the
|
|
form C<package_ver.orig.tar.gz> (suffix depending on initial compression).
|
|
|
|
=back
|
|
|
|
B<dpt repack> invokes F<debian/repack.local> in an environment where B<rm> and
|
|
B<mv> are replaced with functions that reflect the operations in the
|
|
F<MANIFEST> file, if present.
