3# Run this script to regenerate descriptor.pb.{h,cc} after the protocol
4# compiler changes.  Since these files are compiled into the protocol compiler
5# itself, they cannot be generated automatically by a make rule.  "make check"
6# will fail if these files do not match what the protocol compiler would
7# generate.
8#
9# HINT:  Flags passed to generate_descriptor_proto.sh will be passed directly
10#   to make when building protoc.  This is particularly useful for passing
11#   -j4 to run 4 jobs simultaneously.
