# Proto Build Script for envoy_data_plane
#
# This script builds protocol buffer files from the envoy_data_plane repository.
#
# Tested and working with:
#   envoy_data_plane commit: 86181df8ddb05f1d07994e58374fb93139d2bb70
#
# Dependencies are managed in pyproject.toml [dependency-groups.proto]:
#
# Environment variables:
#   USE_HTTPS: Set to "true" to use HTTPS instead of SSH for git clone (default: false)
#              Useful for CI/CD environments like GitHub Actions
