# $Header: //depot/main/tools/include/commonrules#21 $
#
# 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.
#
#
