Patch idea from Debian, but modified considerably in implementation:

[sgt/puzzles] / Recipe

# -*- makefile -*-
# 
# This file describes which puzzle binaries are made up from which
# object and resource files. It is processed into the various
# Makefiles by means of a Perl script. Makefile changes should
# really be made by editing this file and/or the Perl script, not
# by editing the actual Makefiles.
