#!/usr/bin/env bash
# Generate Python protobuf bindings using a specific protoc version.

# Usage:
#   wandb/proto/generate-proto.sh <protoc_version> <output_dir>
#
# Example:
#   wandb/proto/generate-proto.sh 27.0 wandb/proto/v5
#
# Protoc binaries are cached in .protoc/<version>/ at the repo root.
