+# This Makefile is designed to work around namespace conflicts that occur when
+# multiple repositories depend on .proto files with generic filenames. Due to
+# the way protobuf registers files (e.g., foo.proto or pb/foo.proto), naming
+# collisions can occur when the same filename is used across different
+# packages.
+#
+# The only way to generate a *.pb.go file that includes the full package path
+# (e.g., github.com/org/repo/pb/foo.proto) is to place the .proto file in a
+# directory structure that mirrors its package path.
