+Historically this program generates postrm and prerm commands that run the
+init scripts by hand. In V4 mode, it uses the invoke-rc.d program instead.
+See L<debhelper(1)> for details about V4 mode. If you decide to use this, you
+should make your package depend on sysvinit (>= 2.80-1) (this dependency is
+added to ${misc:Depends} by this program in V4 mode).
