+# * If it's expected that two or more targets should be made in sequence
+#   then the target names will differ in numeric components, such that
+#   lexical ordering of the target names matches the expected order
+#   in which the targets should be made.
+#
+# Targets may echo ${PARALLEL_TARG} to print a modified version
+# of their own name, in which alphabetic components like ".a" or ".b"
+# are converted to ".*".  Two targets that are expected to
+# be made in parallel will thus print the same strings, so that the
