"""
Dataset management tool for operations NOT requiring Isaac Sim (SimulationApp).

This script handles dataset operations that do not require the Isaac Sim application:
- inspect: Inspect dataset metadata
- read: Read dataset states
- augment: Add end-effector pose to dataset
- merge: Merge multiple datasets

For operations requiring Isaac Sim (record, replay), use dataset_sim.py instead."""
