-# Run this script to regenerate descriptor.pb.{h,cc} after the protocol
-# 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.
