# 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.
