# ARCHIVE 
# The following commands are used for generating pipeline spec ts objects via protobuf.js:
# https://github.com/protobufjs/protobuf.js
# Because protobuf.js doesn't support processing for Protobuf.Value yet, we temporarily switched over to use ts-proto:
# https://github.com/stephenh/ts-proto
# Before confirming the ts-proto is useful for KFP use case, I keep the commands below in case we need to switch back to protobuf.js.
