+# itself, they cannot be generated automatically by a make rule.  "make check"
+# will fail if these files do not match what the protocol compiler would
+# generate.

+# HINT:  Flags passed to generate_descriptor_proto.sh will be passed directly
+#   to make when building protoc.  This is particularly useful for passing
+#   -j4 to run 4 jobs simultaneously.
