From f85d28014134076217904885ea339e2f4c438df1 Mon Sep 17 00:00:00 2001
From: Dave Reisner <dreisner@archlinux.org>
Date: Sun, 18 Nov 2012 21:32:46 -0500
Subject: obsolete old-style install hook API

This removes any meaning from the definitions of MODULES, BINARIES,
FILES, and SCRIPT within install hooks. It also removed the deprecated
checked_modules() function, which is replaced by add_checked_modules().

Signed-off-by: Dave Reisner <dreisner@archlinux.org>
