##  Example usage:
##
#   define func
#	auto_ok:
#		$(call startrule,auto) \
#		true && \
#		true && \
#		true    \
#		$(call endrule,auto)

#	auto_fail:

#		find /usr >/dev/null 2>&1 && \
#		false && \
#		true    \
#		$(call endrule,auto)
#   endef
#   $(eval $(func))

# $(1) is the name of the FLM function
# $(2) indicates whether the failure of this rule should be ignored (but still logged)
#      FORCESUCCESS indicates "on"
