Plugs quilt into F<debian/rules> and F<debian/control>. Depends on
F<debian/rules> being in DH7 three-liner format. Also adds debian/README.source
documenting quilt usage.

This package uses quilt for managing all modifications to the upstream
source. Changes are stored in the source package as diffs in
debian/patches and applied during the build.

See /usr/share/doc/quilt/README.source for a detailed explaination.

=item drop_quilt( $control )

removes quilt from F<debian/rules>. Expects that
L<|add_quilt> was used to add quilt to F<debian/rules>.

If F<debian/README.source> exists, references to quilt are removed from it (and
the file removed if empty after that).

Both dh7-style (C<dh --with=quilt>) and old-fashioned (C<$(QUILT_STAMPFN)>
target dependency) are supported.
