# This Makefile.proto has rules to generate *.pb.go files in
# `exporters/otlp/internal/opentelemetry-proto-gen` from the .proto files in
# `exporters/otlp/internal/opentelemetry-proto` using protoc with a go plugin.
#
# The protoc binary and other tools are sourced from a docker image
# `PROTOC_IMAGE`.
#
# Prereqs: The archiving utility `pax` is installed.
