+######################################################################
+### barrier is a helper target that can be used to separate targets
+### that should be built in a new make process from being built in
+### the current one.  The targets that must be built after the "barrier"
+### target invokes a new make should be listed in _BARRIER_POST_TARGETS,
+### and should be of the form:
+###
+###	.if !exists(${_BARRIER_COOKIE})
+###	foo: barrier
+###	.else
+###	foo: foo's real source dependencies
+###	.endif
+###
+### Note that none of foo's real source dependencies should include
+### targets that occur before the barrier.
+###
