6: * These are the internal rules that "make" trucks around with it at
7: * all times. One could completely delete this entire list and just
8: * conventionally define a global "include" makefile which had these
9: * rules in it. That would make the rules dynamically changeable
10: * without recompiling make. This file may be modified to local
11: * needs. There are currently two versions of this file with the
12: * source; namely, rules.c (which is the version running in Columbus)
13: * and pwbrules.c which is my attempt at satisfying the requirements
14: * of PWB systems.
15: * The makefile for make (make.mk) is parameterized for a different
16: * rules file. The macro $(RULES) defined in "make.mk" can be set
17: * to another file and when "make" is "made" the procedure will
18: * use the new file. The recommended way to do this is on the
19: * command line as follows:
20: * "make -f make.mk RULES=pwbrules"
