+If a file named debian/package.config.debhelper exists, the contents
+of that file are merged into the config script as follows: If the script
+exists, then anywhere in it that "#DEBHELPER#" appears, the text of the
+.debhelper file is inserted. If the script does not exist, then a script
+is generated from the .debhelper file. The .debhelper files may be created
+by other debhelper programs, and are shell script fragments.
