+# compiler changes. Since these files are compiled into the protocol compiler
+# 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.
