-# This Makefile.protos has rules to generate go code for otlp
-# exporter. It does it by copying the proto files from
-# `exporters/otlp/internal/opentelemetry-proto` (which is a
-# submodule that needs to be checked out) into `gen/proto`, changing
-# the go_package option to a valid string, generating the go files and
-# finally copying the files into the module. The files are not
-# generated in place, because protoc generates a too-deep directory
-# structure.
-#
-# Currently, all the generated code is in
-# `exporters/otlp/internal/opentelemetry-proto-gen`.
-#
-# Prereqs: wget (for downloading the zip file with protoc binary),
-# unzip (for unpacking the archive), rsync (for copying back the
-# generated files).
