The rationale for using helper scripts in <filename>debian/rules</filename> is
that they let maintainers use and share common logic among many packages. Take
for instance the question of installing menu entries: you need to put the file
-into <filename>/usr/lib/menu</filename> (or <filename>/usr/lib/menu</filename>
+into <filename>/usr/share/menu</filename> (or <filename>/usr/lib/menu</filename>
for executable binary menufiles, if this is needed), and add commands to the
maintainer scripts to register and unregister the menu entries. Since this is
a very common thing for packages to do, why should each maintainer rewrite all
