# Note [Blessed make target file]
#
# make cannot express nicely a single build rule
# with multiple targets:
#
# > all: a b
# > a b:
# > touch a b
#
# This code will run 'touch' rule twice when parallel
# make is used:
# > $ make -j
# > touch a b
# > touch a b
#
# But there is a workaround for it:
# We pick a single file of a group and depend on it
# as an ultimate target. We also need to make sure
# that file has latest timestamp in the group:
#
# > all: a b
# > b:
# > a: b
# > touch a b
# > touch $@
