  11 # Notes:
  12 #       - After including $(ROOT)/usr/include/make/commondefs, a makefile may
  13 #         say ``include $(COMMONRULES)'' to get this file.
  14 #       - It is up to the including makefile to define a default rule before
  15 #         including $(COMMONRULES).
  16 #       - The parent makefile must define TARGETS in order for clobber to work.
  17 #       - If the parent makefile must overload the common targets with special
  18 #         rules (e.g. to perform recursive or subdirectory makes), then set
  19 #         COMMONPREF to some unique prefix before including $(COMMONRULES),
  20 #         and make sure that each common target depends on its prefixed name.
  21 #         For example, a makefile which passes common targets and install on
  22 #         to makes in subdirectories listed in DIRS might say
  23 #
  24 #               COMMONPREF=xxx
  25 #               include $(COMMONRULES)
  26 #
  27 #               $(COMMONTARGS) install: $(COMMONPREF)$$@
  28 #                       @for d in $(DIRS); do \
  29 #                               $(ECHO) "\tcd $$d; $(MAKE) $@"; \
  30 #                               cd $$d; $(MAKE) $@; cd ..; \
  31 #                       done
  32 #
  33 #         Thus, all of the common rules plus install are passed to sub-makes
  34 #         *and* executed in the current makefile (as xxxclean, xxxclobber,
  35 #         xxxinstall, etc).  SUBDIRS_MAKERULE in commondefs is a convenience
  36 #         macro that expands to the above loop.
