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